Shamoon 2 Malware Background
On August 15, 2012, a Saudi Arabian energy company was infected with disk-wiping malware in a targeted attack. The malware, known as either “Shamoon” or “DistTrack,” reportedly infected nearly 30,000 machines at the company in this attack.
Shamoon is highly destructive malware that is capable of spreading to other Windows systems on the network, wiping any infected system at a specified date and time. There is no remediation for affected systems other than restoring from a full backup—the system is rendered inoperable minutes after wiping begins.
Shamoon 2 Campaigns
In November of 2016, this malware resurfaced in a new campaign, again targeting Saudi Arabia. The Shamoon samples discovered as a part of this attack demonstrated nearly identical TTPs to the samples from 2012.
Shamoon appeared again in January of 2017—this time with code modifications that showed greater sophistication and new techniques. Furthermore, researchers have identified new wiper malware (named “StoneDrill”) that is potentially related to the previous Shamoon campaigns, although no active campaign using this malware has been identified.
Shamoon 2 Malware Analysis Report
This report provides detailed analysis of a sample discovered in the first wave of attacks in November 2016, as well as signatures to aid in the detection of this threat on the network. LogRhythm Labs is continuing to monitor activity related to Shamoon and StoneDrill, and will report on the analysis of any future discoveries.
