StoneDrill

Stonedrill is a type of malware that can infiltrate computers or devices and cause harm by stealing personal information, disrupting operations, or holding data hostage for ransom. Stonedrill is a custom malware program that can open a backdoor on an infected computer and download additional files. This malware has been used by the group Elfin to attack various targets. In one incident, a victim in Saudi Arabia was targeted by Elfin and infected with Stonedrill after having previously been attacked by another group called Shamoon. The overlap between HOLMIUM's activities and techniques and those of APT33, StoneDrill, and Elfin have also been noted by other researchers and vendors. As a result of these attacks and the potential damage caused by malware like Stonedrill, it is important for individuals and organizations to take steps to protect their systems. This may include regularly updating anti-virus software, avoiding suspicious downloads and websites, and implementing strong passwords and security measures.
