Earlier this month, security researchers discovered a new peer-to-peer malware with self-spreading capabilities that targets Redis instances running on Internet-exposed Windows and Linux systems.

The Unit 42 researchers who spotted the Rust-based worm on July 11 also found that it hacks into Redis servers that have been left vulnerable to the maximum severity CVE-2022-0543 Lua sandbox escape vulnerability.

"This is due to the volume of potential targets - over 307,000 Redis instances communicating publicly over the last two weeks - and since the worm was able to compromise multiple of our Redis honeypots across disparate regions. However, we don't have an estimate yet of how many nodes exist or how fast the malicious network associated with P2PInfect is growing."

After it connects to the P2P network of other infected devices used for auto-propagation, the worm downloads additional malicious binaries, including scanning tools to find other exposed Redis servers.

Redis servers have been targeted by many threat actors over the years, most of them being added to DDoS and cryptojacking botnets.

Based on the large number of instances exposed online, many Redis server admins may not be aware that Redis lacks a secure-by-default configuration.
