Cozy Bear never really left. Iran denies it suffered a US cyberattack. Malicious WAV files. Darknet dragnet hauls in child exploitation ring. Graboid infests Docker hosts.

Cozy Bear isn’t back--Cozy Bear never really left at all. Iran says the Americans are dreaming: there was no cyberattack in retaliation for Iran’s implausibly deniable missile strikes on Saudi oil fields last month. Malicious audio files are dropping cryptominers and reverse shells into victim systems. An international dragnet collars hundreds in a darknet child exploitation sweep.

Lee from Dragos on their contribution to the Splunk Boss of the SOC (BOTS) capture-the-flag (CTF) competition. Guest is Chris Hickman from Keyfactor on Public Key Infrastructure.
