FrostyGoop’s Zoom-In: A Closer Look into the Malware Artifacts, Behaviors and Network Communications

Unit 42 dissects FrostyGoop OT malware, which sent Modbus TCP commands to disrupt heating for 600+ apartment buildings in Ukraine.

Palo Alto Unit 42 analyzed new FrostyGoop/BUSTLEBERM samples, the ninth known ICS-centric malware, first used against a Ukrainian municipal energy company by sending Modbus TCP commands to ENCO control devices. The attack caused a two-day heating outage affecting over 600 apartment buildings during sub-zero temperatures. The Go-compiled malware accepts Modbus register operations and timing parameters via command-line arguments or a JSON configuration file, uses an obscure open-source Modbus library, and checks the Windows BeingDebugged flag to evade debuggers. Unit 42 telemetry recorded over 1 million Modbus TCP devices exposed to the internet between September and October 2024.

Company Offering ‘100% Human-Written, Never AI’ Medical Research Is Entirely AI

404 Media found Research Gold, advertised as '100% human-written' medical research, is run entirely by AI with fake PhD staff.

Research Gold advertises PRISMA-compliant systematic reviews and meta-analyses drafted by PhD methodologists, but its listed experts are AI-generated personas that do not exist. Real methodologists, including evidence synthesis scientist Jenny Berrio, were listed without permission using photos copied from LinkedIn. Customer calls and quotes were handled by AI agents that insisted they were human, quoting $1,900 for a systematic review.
