Detect string obfuscation from Pikabot
A cybersecurity research team has developed an IDA plugin that can automatically decrypt the string obfuscation of the Pikabot malware loader. The code obfuscation techniques used by the malware to encrypt binary strings, including command and control (C2) server addresses, have previously made Pikabot discovery and technical analysis difficult. Pikabot rose to prominence after the defeat of Qakbot in August 2023 and emerged as a significant threat. Its encryption method involved advanced string encryption techniques that used a combination of AES-CBC and RC4 algorithms, making decryption a complex task for the security experts. Security analysts at Zscaler have now published a...
