Well-known cybersecurity experts claim that data can be wiped using many well-known antivirus programs such as Microsoft, Sentinel One, Trend Micro, Avast, AVG, etc. In a proof-of-concept document titled "Aikido," Safe Breach contributor Or Yair explained how the exploit exploits his Time of Check to Time of Use vulnerability.
The Japanese martial art known as Aikido is characterized by an emphasis on the movement of the opponent and the use of force towards the practitioner.
What is the process?
According to Yair, the flaw can be exploited to enable a variety of "wiper" cyberattacks commonly used in offensive military scenarios. A wiper is a type of virus used in cybersecurity that aims to erase data and applications from an infected computer's hard drive. The attack allows users to "delete files without permission" by redirecting "super-powerful" endpoint detection software.
The entire described procedure involved creating a malicious file in C:tempWindowsSystem32driversndis.sys.
Then the command "AV/EDR Defer Deletion until Next Reboot" is sent with the handle retained. The next step is to "create a shortcut in C:temp > C:" and "delete the C:temp directory" and restart the computer. According to Yair, only a small fraction (perhaps 50%) of the most prominent antivirus companies were affected. His PowerPoint deck, produced by his researchers, lists some of the vulnerable antivirus programs as Microsoft's defenses. According to Yair, only a small fraction (perhaps 50%) of the most prominent antivirus companies were affected. Defender for Endpoint, Sentinel One EDR, Trend Micro Apex One, Avast Antivirus, and AVG Antivirus.
Luckily, products like Palo Alto Networks, XDR, CrowdStrike, McAfee, and Bitdefender were unscathed.
