New campaign targeting security researchers
Over the past several months, the Threat Analysis Group has identified an ongoing campaign targeting security researchers working on vulnerability research and development at different companies and organizations. The actors behind this campaign, which we attribute to a government-backed entity based in North Korea, have employed a number of means to target researchers which we will outline below. We hope this post will remind those in the security research community that they are targets to government-backed attackers and should remain vigilant when engaging with individuals they have not previously interacted with.
In order to build credibility and connect with security researchers, the actors established a research blog and multiple Twitter profiles to interact with potential targets. They’ve used these Twitter profiles for posting links to their blog, posting videos of their claimed exploits and for amplifying and retweeting posts from other accounts that they control.
Their blog contains write-ups and analysis of vulnerabilities that have been publicly disclosed, including “guest” posts from unwitting legitimate security researchers, likely in an attempt to build additional credibility with other security researchers.
While we are unable to verify the authenticity or the working status of all of the exploits that they have posted videos of, in at least one case, the actors have faked the success of their claimed working exploit. On Jan 14, 2021, the actors shared via Twitter a YouTube video they uploaded that proclaimed to exploit CVE-2021-1647, a recently patched Windows Defender vulnerability. In the video, they purported to show a successful working exploit that spawns a cmd.exe shell, but a careful review of the video shows the exploit is fake. Multiple comments on YouTube identified that the video was faked and that there was not a working exploit demonstrated. After these comments were made, the actors used a second Twitter account (that they control) to retweet the original post and claim that it was “not a fake video.”

VisualDoor: SonicWall SSL-VPN Exploit
TL;DR: SonicWall “Virtual Office” SSL-VPN Products ship an ancient version of Bash vulnerable to ShellShock, and are therefore vulnerable to unauthenticated remote code execution (as a “nobody” user) via the /cgi-bin/jarrewrite.sh URL.
The exploit is incredibly trivial. We simply spaff a shellshock payload containing a bash /dev/tcp backconnect at it, and we get a shell. Now, the environment on these things is incredibly limited – its stripped down Linux. But we have bash, openssl, and FTP. So you could always download your own toolkit for further exploitation.
Anyway, here is the public exploit. It is incredibly trivial and recycles the telnetlib handler for reverse shells from exploits released by Stephen Seeley. https://github.com/darrenmartyn/visualdoor.

Hacker blunder leaves stolen passwords exposed via Google search
Source: Hacker blunder leaves stolen passwords exposed via Google search
Hackers hitting thousands of organizations worldwide in a massive phishing campaign forgot to protect their loot and let Google the stolen passwords for public searches.
The phishing campaign has been running for more than half a year and uses dozens of domains that host the phishing pages. It received constant updates to make the fraudulent Microsoft Office 365 login requests look more realistic.
Creds in plain sight
Despite relying on simple techniques, the campaign has been successful in bypassing email protection filters and collected at least 1,000 login credentials for corporate Office 365 accounts.
Researchers at cybersecurity companies Check Point and Otorio analyzing this campaign discovered that the hackers exposed the stolen credentials to the public internet.
In a report published today, they explain that the attackers exfiltrated the information to domains they had registered specifically for the task. Their mistake was that they put the data in a publicly visible file that Google indexed.
As a result, Google could show results for queries of a stolen email address or password, as seen in the screenshot above:

List of DNSpooq vulnerability advisories, patches, and updates
Yesterday, seven Dnsmasq vulnerabilities were disclosed, collectively known as DNSPooq, that attackers can use to launch DNS Cache Poisoning, denial of service, and possibly remote code execution attacks, on affected devices.
Dnsmasq is a widely used open-source Domain Name System (DNS) forwarding application commonly installed on routers, operating systems, access points, and other networking equipment.
Vendors have started to release information on how customers can protect themselves from DNSPooq. To make it easier to find this information, BleepingComputer will be listing security advisories as they are released.
The related CVEs from JSOF’s DNSpooq advisory are listed below, along with their descriptions.
| Name | CVSS | Description |
|---|---|---|
| CVE-2020-25681 | 8.1 | Dnsmasq versions before 2.83are susceptible to a heap-based buffer overflow in sort_rrset() when DNSSEC is used. This can allow a remote attacker to write arbitrary data into target device’s memory that can lead to memory corruption and other unexpected behaviors on the target device. |
| CVE-2020-25682 | 8.1 | Dnsmasq versions before 2.83 are susceptible to buffer overflow in extract_name() function due to missing length check, when DNSSEC is enabled. This can allow a remote attacker to cause memory corruption on the target device. |
| CVE-2020-25683 | 5.9 | Dnsmasq versions before 2.83 are susceptible to a heap-based buffer overflow when DNSSEC is enabled. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in dnsmasq, resulting in a Denial of Service. |
| CVE-2020-25687 | 5.9 | Dnsmasq versions before 2.83are vulnerable to a heap-based buffer overflow with large memcpy in sort_rrset() when DNSSEC is enabled. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in sort_rrset() and cause a crash in dnsmasq, resulting in a Denial of Service. |
| CVE-2020-25684 | 4 | A lack of proper address/port check implemented in dnsmasq versions |
| CVE-2020-25685 | 4 | A lack of query resource name (RRNAME) checks implemented in dnsmasq’s versions before 2.83 reply_query function allows remote attackers to spoof DNS traffic that can lead to DNS cache poisoning. |
| CVE-2020-25686 | 4 | Multiple DNS query requests for the same resource name (RRNAME) by dnsmasq versions before 2.83 allows for remote attackers to spoof DNS traffic, using a birthday attack (RFC 5452), that can lead to DNS cache poisoning. |
BleepingComputer suggests checking this page throughout the coming days to see if new information is available for devices you may be using.

President Biden’s Peloton exercise equipment under scrutiny
President Joe Biden can’t bring his Peloton exercise equipment to the White House due to security reasons.
Peloton devices are connected online and are equipped with a camera and microphone that give the users an immersive experience and communications capabilities. On the other side, these features pose a potential risk to the user in case of a hack, and President Joe Biden is a privileged target.
To secure the exercise equipment, Biden’s Peloton may have to be modified, removing the microphone, camera and networking equipment.
“If you really want that Peloton to be secure, you yank out the camera, you yank out the microphone, and you yank out the networking equipment … and you basically have a boring bike,” Max Kilger, Ph.D., director of the Data Analytics Program and Associate Professor in Practice at the University of Texas at San Antonio, told Popular Mechanics. “You lose the shiny object and the attractiveness.”

Microsoft’s Pluton chip upgrades the hardware security of Windows PCs
The next Windows PC you buy could come with an advanced security co-processor that will protect your data from being stolen by hackers.
The next Windows PC you buy could come with an advanced security co-processor that will protect your data from being stolen by hackers. Building on work it started with the Xbox One, on Tuesday Microsoft announced the existence of Pluton. It’s a new project the company is working on with both AMD and Intel, as well as Qualcomm, to create x86 and ARM CPUs that integrate a dedicated security component.
At its simplest, Pluton is an evolution of the existing Trusted Platform Module (TPM) you find in many modern computers. TPMs store security-related information about your operating system and enable features like Windows Hello. However, for all the additional security they add to PCs, they still have vulnerabilities. As security researchers have shown, it’s possible for hackers to attack the bus interface that allows the TPM and CPU to communicate with one another.
That’s where Pluton comes into the picture. By integrating the TPM into the CPU, Microsoft says it’s able to close off that avenue of attack. When the first slate of Pluton-equipped CPUs and computers start making their way out to consumers, Microsoft says they’ll emulate TPM chips so that they can take advantage of existing APIs and provide Windows users with immediate usefulness. The end goal is for Pluton-equipped CPUs to protect your credentials, encryption keys and personal data. In that way, it will be similar to the T2 and Titan M security chips Apple and Google offer, but with the added advantage of being there for the entire Windows ecosystem to use.

Pwn2Own Tokyo Day one: NETGEAR Router, WD NAS Device hacked
Pwn2Own Tokyo 2020 hacking competition is started, bug bounty hunters already hacked a NETGEAR router and a Western Digital NAS devices.
The Pwn2Own Tokyo is actually coordinated by Zero Day Initiative from Toronto, Canada, and white hat hackers taking part in the competition have to demonstrate their ability to find and exploit vulnerabilities in a broad range of devices.
On the day one of the competition, bug bounty hunters have successfully hacked a vulnerability in the NETGEAR Nighthawk R7800 router. The participants were the Team Black Coffee, Team Flashback, and teams from cybersecurity firms Starlabs and Trapa Security, and the Team Flashback earned $20,000 for a remote code execution exploit that resulting from the chaining of two bugs in the WAN interface.
“The team combined an auth bypass bug and a command injection bug to gain root on the system. They win $20,000 and 2 points towards Master of Pwn.” reads the post on the official site of the Pwn2Own Tokyo 2020.
The Trapa team successfully chained a pair of bugs to gain code execution on the LAN interface of the router, the experts earned $5,000 and 1 point towards Master of Pwn.
The STARLabs team earned the same amount after using a command injection flaw to take control of the device.
The Western Digital My Cloud Pro series PR4100 NSA device was targeted by The Trapa Security team also earned $20,000 for a working exploit for the Western Digital My Cloud Pro series PR4100 NSA device.
The exploit code chained an authentication bypass bug and a command injection vulnerability to gain root on the device.

Spotting a Common Scam
Spotting a Common ScamÂ
These scams seek to collect personal information about you, often appearing to come from a real business or agency. Someone may pose as an official disaster aid worker, or send you a fraudulent COVID contact tracing email. If you receive a message with a link, you should not click it as it may download malware to your device to steal passwords and personal information. Government agencies like FEMA or the IRS will never contact you asking for a FEMA registration number, a Social Security number, or a bank account or credit card number to give you a COVID or FEMA payment—or ask you to pay anything up front to fill out an application or to access state or federal resources.
Before sharing, check that what you are reading is from a trustworthy source. Disinformation can be life threatening in a global pandemic.
No cures or vaccines have been approved for COVID-19 yet. Online offers claiming to provide a medicine or device to treat or prevent COVID should be ignored. When there is a new breakthrough in the treatment and prevention of COVID, it will be widely reported on by reputable news sources.
Fake charities often emerge following a crisis, soliciting donations, but not using them for the described purpose. Before donating, check out www.ftc.gov/charity  to research the organization and make sure it’s legitimate.
If you receive a robocall, you should hang up instead of pushing any buttons or giving away any personal information. If a call claims to be from the IRS or FEMA, but demands immediate payment through debit card or wire transfer, it is fraudulent. Federal agencies will never demand immediate payment over the phone, threaten immediate arrest, or ask you to make a payment to anyone other than the U.S. Treasury.
Warning Signs that a Loved One may be the Victim of a ScamÂ
Victims to a scam may be embarrassed or uncomfortable asking for help. It’s not always obvious when someone has been scammed, so check in with your loved ones frequently, especially if they are older, live alone, or are otherwise high risk.
Warning signs include large ATM withdrawals, charges, or checks; secretiveness and increased anxiety about finances; large quantities of goods being delivered that they do not need; an unusual number of phone calls or visits from strangers; and a sudden lack of money, unpaid bills, or a change in daily habits.
For more information, and to get help with a potential FEMA fraud, you can call the National Center for Disaster Fraud Hotline at 866-720-5721 or FEMA’s Public Inquiry Unit at 916-210-6276. For questions about pandemic scams, go to www.ftc.gov/coronavirus or www.cdc.goc/coronavirus/2019-ncov .
