About this episode
Tillmann Werner discusses unresolved cyberattacks and the evolution of technology in solving cold cases in cybersecurity.
Not all cybercrimes are resolved. Some threat groups disappear completely, and some malware is never seen again. But sometimes, a long-dormant case is cracked open and elusive answers are found. Tillmann Werner, VP of Intelligence Production at CrowdStrike, has been a member of the CrowdStrike Intelligence team since 2012 and has analyzed many of these cold cases. In this episode, he joins Adam to chat about unresolved cyberattacks, the adversaries behind them, and cases that remained inactive for years before new technology or data allowed experts to close them. While it’s frustrating to close a file without success, Tillmann says, the evolution of technology and proliferation of data often help solve old cases that have collected dust. Tune in to hear Adam and Tillmann look back at decades-old eCrime and nation-state campaigns, some of which now have answers — and others that remain a mystery.
