After the infection is achieved, the fake secure32 DLL file is used to download the mining software on to the victim's system.
You can always remove the rights at any point of. If you share a OneDrive file with someone, then obviously those people have access. So, nothing to worry about confidentiality and security. It is like your local drive, my documents or desktop. For persistence, the threat actors have set the OneDrive.exe process to run on every reboot. By default, only YOU can see OneDrive files. It is placed inside %LocalAppData%\Microsoft\OneDrive\ so that it loads up alongside OneDrive's own processes. Bitdefender observed the campaign between May and July 2022 and in this span, over 700 instances of the cryptojacking were detected where similar exploits were made.Īccording to the report, the attackers are relying on a maliciously written secure32.dll file to infect the systems of potential victims. The campaign has been using the dynamic link library (DLL) hijacking or side-loading vulnerability exploit in OneDrive to carry out the operations. In the latest such development, anti-virus maker Bitdefender has discovered that Microsoft's OneDrive was being used a group of threat actors for cryptojacking purposes. And the nefarious ones out there tend to employ crypto-jacking, where they secretly use a victim's computer or any other device to mine cryptocoins. Some of the others however devised other ways to get around the cost of buying expensive mining equipment.
As such, many were busy getting rid of their expensive GPU rigs right before it happened. The recent Ethereum merge has brought generally bad news for most miners.
