P2PInfect Worm Utilizes New and Sophisticated Techniques
The P2PInfect worm, operating as a peer-to-peer botnet, has caught the attention of security researchers for its usage of previously unreported initial access methods to target vulnerable Redis servers.
Cado Security researchers have discovered that the malware exploits the Redis data store’s replication feature, particularly the SLAVEOF command, to compromise exposed instances of Redis.
The sophisticated worm, coded in Rust, is designed to replicate malicious instances and activate infections on compromised servers.
Multiple Exploits for Initial Access
Notably, the P2PInfect worm has demonstrated the ability to leverage multiple exploits for its initial access. While the exploitation of the SLAVEOF command is a common attack pattern against Redis in cloud environments, this campaign has added new attack vectors to its arsenal.
Another method involves registering a malicious cron job on the Redis host, which downloads the malware from a remote server upon execution. This technique has been previously observed in attacks by the WatchDog cryptojacking group.
A Self-Propagating Peer-to-Peer Botnet
The P2PInfect malware distinguishes itself with its self-propagating nature as a peer-to-peer botnet. Each infected server serves as a node that establishes connections with other infected servers, facilitating gossiping among them without relying on a centralized command-and-control (C2) server.
This decentralized approach enhances the malware’s resilience and evades traditional detection methods.
P2PInfect’s Worming Behavior
The worming behavior of P2PInfect enables it to expand its reach across networks. It employs a list of passwords to carry out brute-force attacks on SSH servers, attempting to exploit the Lua sandbox escape vulnerability or using the SLAVEOF command to compromise Redis servers.
The malware aims to grow the botnet to a specific size to carry out future attacks, including the deployment of cryptocurrency miners.
Sophisticated and Portable Rust Code
The use of Rust as the coding language provides P2PInfect with various advantages. Rust’s versatility allows the malware to be easily ported across platforms, with Windows and Linux binaries sharing significant portions of the same code.
Furthermore, the employment of Rust makes static code analysis significantly more challenging for security researchers, adding to the malware’s ability to evade detection.
Conclusion
The discovery of P2PInfect’s advanced and undocumented breach methods emphasizes the need for robust cybersecurity measures, especially for Redis servers.
Its worming behavior and evasion tactics pose a considerable threat to network security, necessitating vigilance and prompt action to protect against such sophisticated malware.
