P2Pinfect Worm Now Delivering Ransomware on Redis Servers

 

Cado Security experts warned that the P2Pinfect worm is used in attacks on Redis servers to deliver ransomware and cryptocurrency mining payloads. 

Palo Alto Networks Unit 42 researchers uncovered the P2P worm P2PInfect in July 2023, which targets Redis servers running Linux and Windows operating systems. P2PInfect’s ability to target Redis servers running on both Linux and Windows operating systems makes it more expandable and dangerous than other worms.

Cado Security Labs identified a new strain of the P2Pinfect botnet in December 2023, specifically targeting routers, IoT devices, and other embedded devices. This variation was built for the Microprocessor without Interlocked Pipelined Stages (MIPS) architecture.

The new bot includes enhanced evasion methods, the ability to evade execution in a Virtual Machine (VM) or a debugger, and anti-forensics support for Linux hosts. 


The worm is written in Rust and targets Redis instances using the Lua sandbox escape vulnerability CVE-2022-0543 (CVSS score 10.0). In September 2023, Cado Security Labs detected a 600x spike in P2Pinfect traffic since August 28.

Researchers noted that the malware did
