The P2PInfect peer-to-peer (P2) worm has been observed employing formerly undocumented original entry methods to breach susceptible Redis servers and rope them into a botnet.
“The malware compromises exposed situations of the Redis knowledge shop by exploiting the replication characteristic,” Cado Security researchers Nate Monthly bill and Matt Muir mentioned in a report shared with The Hacker News.
“A popular attack pattern towards Redis in cloud environments is to exploit this aspect utilizing a malicious occasion to allow replication. This is achieved via connecting to an exposed Redis instance and issuing the SLAVEOF command.”
The Rust-primarily based malware was 1st documented by Palo Alto Networks Device 42, contacting out the malware’s capability to exploit a critical Lua sandbox escape vulnerability (CVE-2022-0543, CVSS rating: 10.) to get hold of a foothold into Redis circumstances. The marketing campaign is thought to have commenced on or immediately after June 29, 2023.
However, the hottest discovery indicates that the menace actors powering the campaign are leveraging several exploits for preliminary accessibility.
This is not the to start with time the SLAVEOF command has been abused in the wild. Formerly, risk actors involved with malware families this kind of as H2Miner and HeadCrab have abused the attack procedure to illicitly mine cryptocurrency on compromised hosts.
In performing so, the purpose is to replicate a malicious instance and load a malicious module to activate the an infection.
A different initial access vector involves the registration of a malicious cron job on the Redis host to obtain the malware from a distant server on execution, a approach earlier observed in attacks mounted by the WatchDog cryptojacking team.
A thriving breach is adopted by the distribution of up coming-stage payloads that make it possible for the malware to change iptables firewall guidelines at will, up grade itself, and probably deploy cryptocurrency miners at a later date as soon as the botnet has grown to a certain dimension.

“The P2Pinfect malware tends to make use of a peer-to-peer botnet,” the scientists said. “Each individual contaminated server is dealt with as a node, which then connects to other infected servers. This makes it possible for the total botnet to gossip with each individual other without utilizing a centralized C2 server.”
A notable trait of the botnet is its worming actions, enabling it to expand its reach by employing a listing of passwords to brute-force SSH servers and trying to exploit the Lua sandbox escape vulnerability or use the SLAVEOF command in the scenario of Redis servers.
“P2Pinfect is well-developed and utilizes refined methods for replication and C2,” the researchers concluded. “The choice of utilizing Rust also lets for simpler portability of code across platforms (with the Windows and Linux binaries sharing a good deal of the identical code), while also making static assessment of the code noticeably more difficult.”
