A new Go-based malware threat that researchers call Redigo has been targeting Redis servers vulnerable to CVE-2022-0543 to plant a stealthy backdoor and allow command execution.
Today, AquaSec reports that its Redis honeypots vulnerable to CVE-2022-0543 caught a new piece of malware that is not detected as a threat by antivirus engines on Virus Total.
AquaSec says that Redigo attacks start with scans on port 6379 to locate Redis servers exposed on the open web.
The attackers simulate normal Redis communication over port 6379 to evade detection by network analysis tools while attempting to hide traffing from Redigo's command and control server.
AquaSec says it's likely that the ultimate goal of Redigo is to add the vulnerable server as a bot in a network for distributed denial-of-service attacks or to run cryptocurrency miners on the compromised systems.
Since Redis is a database, accessing the data to steal it would also be a plausible scenario in Redigo attacks.
