Cado Security Labs Exposes P2Pinfect Botnet’s Sophisticated Attack Techniques

In the ever-evolving landscape of cyber threats, a new menace lurks in the digital shadows, targeting the very core of our interconnected world. Cado Security Labs delves into the intricate details of “P2Pinfect,” a cross-platform botnet that has recently gained notoriety for its sophisticated attack strategies and elusive nature.

Emerging in July 2023, P2Pinfect represents a new breed of botnets crafted with meticulous precision. Written in Rust, this malware acts as a botnet agent, connecting infected hosts in a peer-to-peer topology. Its initial method of attack leveraged Redis, a popular database system, exploiting vulnerabilities such as the CVE-2022-0543 and unauthorized replication attacks for initial access.

In a startling development, researchers at Cado Security Labs have uncovered a new variant of P2Pinfect that specifically targets embedded devices based on 32-bit MIPS processors. This shift in focus to MIPS devices, commonly used in routers and IoT devices, marks a significant escalation in the threat landscape. By exploiting SSH brute force attacks, P2Pinfect aims to infiltrate and compromise these devices, expanding its nefarious network.

One of the most intriguing aspects of P2Pinfect is its advanced evasion techniques. This includes Virtual Machine (VM) detection, debugger detection, and anti-forensics on Linux hosts. The malware employs a novel method of checking the ‘TracerPid’ field in the Linux ‘/proc’ file system to detect dynamic analysis tools, terminating itself if the analysis is detected.

Further analysis revealed that the MIPS variant of P2Pinfect contains an embedded 32-bit Windows DLL, a characteristic feature of the original P2Pinfect samples. This highlights the botnet’s cross-platform capabilities and the developers’ commitment to hindering analysis and detection.

The continuous development and sophistication of P2Pinfect demonstrate that it is operated by a highly skilled threat actor. The use of evasion techniques, targeting MIPS devices, and the cross-platform nature of the malware indicate a botnet poised for significant growth and potential impact.

P2Pinfect serves as a stark reminder of the dynamic and complex nature of modern cyber threats. It underscores the need for constant vigilance and advanced cybersecurity measures to combat these evolving menaces.
