Penetration Testing
Penetration Testing is a method that many companies follow in order to minimize their security breaches. This is a controlled way of hiring a professional who will try to hack your system and show you the loopholes that you should fix.
Before doing a penetration test, it is mandatory to have an agreement that will explicitly mention the following parameters −
>what will be the time of penetration test,
>where will be the IP source of the attack, and
>what will be the penetration fields of the system.
Penetration testing is conducted by professional ethical hackers who mainly use commercial, open-source tools, automate tools and manual checks. There are no restrictions; the most important objective here is to uncover as many security flaws as possible.

The Security Mirage
The feeling of security and the reality of security don’t always match, says computer-security expert Bruce Schneier. In his talk, he explains why we spend billions addressing news story risks, like the “security theater” now playing at your local airport, while neglecting more probable risks — and how we can break this pattern.

Vovalex is likely the first ransomware written in D
A new ransomware called Vovalex is being distributed through fake pirated software that impersonates popular Windows utilities, such as CCleaner.
When it comes down to it, all ransomware infections boil down to the same function – encrypt a device’s files and then drop a ransom note demanding payment in some form.
While Vovalex is no different, what stands out to Advanced Intel’s Vitali Kremez and MalwareHunterTeam, who found the ransomware, is that it may be the first ransomware written in D.

Lebanese Cedar APT group broke into telco and ISPs worldwide
Clearsky researchers linked the Lebanese Cedar APT group to a cyber espionage campaign that targeted companies around the world.
Clearsky researchers linked the Lebanese Cedar group (aka Volatile Cedar) to a cyber espionage campaign that targeted companies around the world.
The APT group has been active since 2012, experts linked the group to the Hezbollah militant group.
The activities of the group were first spotted by Check-Point and Kaspersky labs in 2015.
ClearSky experts linked the Lebanese Cedar group to intrusions at telco companies, internet service providers, hosting providers, and managed hosting and applications companies.
The attacks began in early 2020 and threat actors breached internet service providers in the US, the UK, Egypt, Israel, Lebanon, Jordan, the Palestinian Authority, Saudi Arabia, and the UAE.
“Based on a modified JSP file browser with a unique string that the adversary used to deploy ‘Explosive RAT’ into the victims’ network, we found some 250 servers that were apparently breached by Lebanese Cedar” reads the report published by the ClearSky. “We assess that there are many more companies that have been hacked and that valuable information was stolen from these companies over periods of months and years.”

TeamTNT group adds new detection evasion tool to its Linux miner
The TeamTNT cybercrime group has upgraded their Linux cryptocurrency miner by adding open-source detection evasion capabilities, AT&T Alien Labs researchers warn.
Early this year, researchers from Trend Micro discovered that the TeamTNT botnet was improved with the ability to steal Docker credentials.
The TeamTNT botnet is a crypto-mining malware operation that has been active since April 2020 and that targets Docker installs. The activity of the TeamTNT group has been detailed by security firm Trend Micro, but in August experts from Cado Security discovered that that botnet is also able to target misconfigured Kubernetes installations.
“The group is using a new detection evasion tool, copied from open source repositories,” reads the analysis published by AT&T Alien Labs.
The threat actor behind the botnet used the new tool to hide the malicious process from process information programs such as `ps` and `lsof`and evading the detection.
The libprocesshider open-source tool is available on Github since 2014 and is able to “hide a process under Linux using the ld preloader.” The “preloading” technique allows the system to load a custom shared library before other system libraries are loaded. If the custom shared library exports a function with the same signature of a library that is located in the system libraries, the custom version will override it.

Attacks have specifically targeted the healthcare sector during the COVID-19 pandemic, taking advantage of the global crisis to extort victims.”
The group has been active since 2019, the NetWalker ransomware has been offered with the Ransomware-as-a-Service (RaaS) model.
The list of victims of the group is long, it includes Pakistan’s largest private power company K-Electric, Argentina’s official immigration agency, Dirección Nacional de Migraciones, and the University of California San Francisco (UCSF), the latter paid a $1.14 million ransom to recover its files.
