Researchers crack open unusually advanced malware that hid for 5 years [View all]
Source: Arstechnica
Security experts have discovered a malware platform that's so advanced in its design and execution that it could probably have been developed only with the active support of a nation state.
The malware—known alternatively as "ProjectSauron" by researchers from Kaspersky Lab and "Remsec" by their counterparts from Symantec—has been active since at least 2011 and has been discovered on 30 or so targets. Its ability to operate undetected for five years is a testament to its creators, who clearly studied other state-sponsored hacking groups in an attempt to replicate their advances and avoid their mistakes. State-sponsored groups have been responsible for malware like the Stuxnet- or National Security Agency-linked Flame, Duqu, and Regin. Much of ProjectSauron resides solely in computer memory and was written in the form of Binary Large Objects, making it hard to detect using antivirus.
Part of what makes ProjectSauron's so impressive is its ability to collect data from air-gapped computers. To do this, it uses specially prepared USB storage drives that have a virtual file system that isn't viewable by the Windows operating system. To infected computers, the removable drives appear to be approved devices, but behind the scenes are several hundred megabytes reserved for storing data that is kept on the air-gapped machines. The arrangement works even against computers in which data-loss prevention software blocks the use of unknown USB drives.
Kaspersky researchers still aren't sure precisely how the USB-enabled exfiltration works. The presence of the invisible storage area doesn't in itself allow attackers to seize control of air-gapped computers. The researchers suspect the capability is used only in rare cases and requires use of a zero-day exploit that has yet to be discovered. In all, Project Sauron is made up of at least 50 modules that can be mixed and matched to suit the objectives of each individual infection.

The ability to jump the gap is crazy stuff.
