#173 - Intel Chat: ClickFix, Raspberry Robin, Gelsemium, Fancy Bear & Salt Typhoon
Update: 2024-11-28
Description
In this episode of The Cybersecurity Defenders Podcast, we discuss some cutting-edge intel coming out of LimaCharlie's community Slack channel.
- In recent months, cybersecurity researchers have observed a surge in the use of a social engineering technique known as "ClickFix." This method involves threat actors presenting users with deceptive error messages that prompt them to manually execute malicious commands, often by copying and pasting scripts into their systems.
- Raspberry Robin, also known as Roshtyak, is a highly obfuscated malware first discovered in 2021, notable for its complex binary structure and advanced evasion techniques. It primarily spreads via infected USB devices and employs multi-layered execution to obscure its true purpose.
- A China-linked Advanced Persistent Threat (APT) group, Gelsemium, has been observed targeting Linux systems for the first time, deploying previously undocumented malware in an espionage campaign. Historically known for targeting Windows platforms, this new activity signifies a shift towards Linux, possibly driven by the increasing security of Windows systems.
- Russia’s APT28 hacking group, also known as Fancy Bear or Unit 26165, has developed a novel technique dubbed the “nearest neighbor attack” to exploit Wi-Fi networks remotely.
- Hackers linked to the Chinese government, known as Salt Typhoon, have deeply infiltrated U.S. telecommunications infrastructure, gaining the ability to intercept unencrypted phone calls and text messages. The group exploited vulnerabilities in the wiretap systems used by U.S. authorities for lawful interception, marking what Senator Mark Warner has called "the worst telecom hack in our nation's history."
