In this episode, we dive deep into the underground cybercrime ecosystem powering the surge of modern infostealers—Stealc, Vidar, and LummaC2. These malware strains aren’t just code—they’re full-service products sold as Malware-as-a-Service (MaaS), giving even low-skilled attackers access to powerful data theft tools.
We break down how these stealers are delivered through clever deception tactics like ClickFix, which uses fake pop-ups on shady streaming sites to trick users into pasting malicious PowerShell commands. We also explore drive-by downloads masquerading as cracked software and how attackers abuse legitimate tools like mshta and PowerShell to silently deploy and persist infostealers on victim machines.
From obfuscation techniques that thwart static analysis to the use of browser-based panels that manage infections and exfiltrated data, we reveal how these stealers target everything from browser credentials to cryptocurrency wallets and messaging apps. We’ll also unpack the advanced persistence methods and evasion techniques being deployed—including anti-VM checks, script encoding, and dynamic WinAPI loading.
With new variants like Stealc V2 introducing MSI-based payloads, streamlined C2 communication, and multi-monitor screenshot capture, defenders face an increasingly complex landscape. We discuss how behavioral detection, threat intelligence, and advanced obfuscation detection techniques like Logistic Regression with Gradient Descent are becoming essential in combating these evolving threats.
Tune in for a frontline briefing on how infostealers operate today—and what it will take to stop them.
