BendyBear: difficult to detect and downloader of malicious payloads. [Research Saturday]

Guest Jen Miller-Osborn from Palo Alto Networks' Unit 42 joins us to discuss their research into BendyBear. Highly malleable, highly sophisticated and over 10,000 bytes of machine code. The code behavior and features strongly correlate with that of the WaterBear malware family, which has been active since as early as 2009. The malware is associated with the cyber espionage group BlackTech, which many in the broader threat research community have assessed to have ties to the Chinese government, and is believed to be responsible for recent attacks against several East Asian government organizations. Due to the similarities with WaterBear, and the polymorphic nature of the code, Unit 42 named this novel Chinese shellcode “BendyBear.” It stands in a class of its own in terms of being one of the most sophisticated, well-engineered and difficult-to-detect samples of shellcode employed by an Advanced Persistent Threat (APT).
