At least 1,200 Redis database servers worldwide have been corralled into a botnet using an “elusive and severe threat” dubbed HeadCrab since early September 2021.
“This advanced threat actor utilizes a state-of-the-art, custom-made malware that is undetectable by agentless and traditional anti-virus solutions to compromise a large number of Redis servers,” Aqua security researcher Asaf Eitani said in a Wednesday report.
A significant concentration of infections has been recorded in China, Malaysia, India, Germany, the U.K., and the U.S. to date. The origins of the threat actor are presently unknown.
