RiskIQ this morning warned of information-stealing ad-clicking malware that's being offered via warning pop-ups on Samsung Android devices.

Deep Instinct describes Mylobot, a new and sophisticated botnet currently active in the wild. It's not clear what Mylobot's controllers are after, and it's also unclear how it's delivered, but it's not an amateur performance. Among its features are methods of evading sandboxes and debuggers, and of reflective execution of EXE files directly from memory. It's also patient, remaining quiescent for two weeks after installation before it makes its calls to the command-and-control servers. It also removes competing malware from the systems it infects. Researchers say it bears some similarity to Locky ransomware. Mylobot can establish complete control over victim devices, delivering whatever payloads its unknown masters may wish to install.
