Shamoon

Shamoon is a type of malware, specifically a wiper, known for its destructive capabilities. This malicious software was notably involved in the attack on Saudi Aramco, where it crashed over 30,000 workstations, demonstrating its potential to disrupt operations significantly. The threat actors BlackJack and Twelve have both been found to use variants of Shamoon in their attacks. A particular variant of Shamoon, written in Go, was identified in the attacks by these groups, marking a shift from the original version written in C# that became available due to a leak. The connection between these groups is further strengthened by the identical directories in which they place the Shamoon wiper or its components during their attacks. Furthermore, an instance was recorded where a victim in Saudi Arabia was attacked by another threat group, Elfin, and infected with the Stonedrill malware, shortly after falling victim to a Shamoon attack. This suggests a possible coordination or at least a shared target list among different cybercriminal groups. The widespread use of Shamoon has had significant implications on perceptions of cybersecurity, particularly in the Middle East. Following high-profile cyberattacks such as the Stuxnet attack and the Shamoon wiper attacks, nations in the region began establishing cybersecurity and data-protection frameworks in 2014. Despite the lack of sophistication in the Shamoon wiper virus, its effectiveness in causing disruption underscores the importance of robust cybersecurity measures. It's worth noting that this malware, along with others like AcidRain, doesn't need to be sophisticated to be effective, indicating a shift in the landscape of cyber threats.
