The US government has issued a warning about the Russian cybercrime gang stepping up its attacks against hospitals and health clinics by flooding their networks and using, as part of its warning, a free tool that is designed to help organizations defend against KillNet distributed-denial-of-service (DDoS) bots.
Currently, tens of thousands of proxy IP addresses are listed on the KillNet open proxy IP blocklist. These IP addresses are being used by Russian hackers in their attempts to flood networks with traffic. Following the investigation that SecurityScorecard’s threat researchers conducted on Killnet and other network spamming miscreants, the security company built this list of threats.
Although DDoS attacks are relatively unsophisticated, like many other attacks, they can still take a serious toll, especially when they disrupt hospitals, according to a recent blog post by the security firm using KillNet as an example.
A website taken down by the Russian gang toward the end of January was one of 14 hospitals targeted in the United States. The University of Michigan Hospitals and Health Centers, Stanford Hospital, Duke University, and Cedars-Sinai Medical Center, among others, were some of the hospitals. There are several reasons for using DDoS attacks, one of which is to mask more intrusive activities.
