The cryptolocker virus was the attack that turned ransomware from a nuisance into a full-blown criminal industry — and in this episode of The Backup Wrap-up, we break down exactly how that happened. W. Curtis Preston (Mr. Backup) sits down with co-host Prasanna Malaiyandi and cybersecurity expert Dr. Mike Saylor to trace the full evolution of ransomware and explain why CryptoLocker was the turning point.
If you've ever wondered how ransomware went from fake pop-up messages to billion-dollar criminal enterprises, this is the episode for you. We start with the earliest days — scareware attacks that did nothing more than frighten you into paying — and walk through the progression of encryption methods that made ransomware increasingly dangerous. Dr. Mike Saylor breaks down the difference between symmetric and asymmetric encryption in plain language, and explains why the move to public-private key pairs made it so much harder for victims to recover without paying up.
Then we get into the cryptolocker virus itself: how it spread through fake FedEx emails, why it kick-started phishing awareness training, what Operation Tovar did to shut it down, and — just as interesting — what the bad guys learned from its failures. We cover the role of the Zeus botnet, how Bitcoin became the payment method of choice, and why ransoms started out at just a few hundred bucks. We also talk about what happened next: the rise of data exfiltration, double extortion, and even triple extortion where attackers go after the victims of the victims.
Plus, we take a side trip into the LastPass breach and pour one out for the guy who lost his crypto fortune in a landfill.
Whether you're in IT, security, or just want to understand how ransomware works, this episode gives you the full picture.
