Malware Wiper

Malware wiper is a malicious software designed to delete all files on the infected system, causing significant damage and losses. This type of malware has been increasingly used in targeted attacks over the past year. Notably, the Russia-affiliated advanced persistent threat (APT) group, Sandworm, has utilized multiple strains of malware wiper to attack Ukrainian entities. These attacks have been ongoing throughout the timeline of Russia's war on Ukraine, which is nearing its one-year mark. The discovery of new malware wiper strains being used by Sandworm highlights the evolving nature of this cyber warfare. In addition to the attacks on Ukraine, another strain of malware wiper known as BiBi-Linux has been identified. This new malware is being used to destroy data in attacks specifically targeting Linux systems owned by Israeli companies. The emergence of BiBi-Linux underscores the global reach of these threats and the necessity for robust cybersecurity measures across different operating systems and geographical locations. The Russian attack on satellite communications revealed at Black Hat was a multi-pronged assault that included not only the Acid Rain malware wiper but also a server flood at Viasat, quickly overwhelming their networks. An executive from Viasat and an NSA official disclosed this information, further emphasizing the complexity and sophistication of these cyberattacks. It is clear that malware wipers have become a favored tool for cybercriminals and state-sponsored actors, necessitating increased vigilance and stronger defenses against such threats.
