INFOSTEALERS: THE SILENT SMASH-AND-GRAB DRIVING MODERN CYBERCRIME

Summary from the TLDR InfoSec newsletter

Modern infostealers operate through a sophisticated malware-as-a-service model, executing complete credential harvests within minutes using silent entry, stealthy data collection (including session cookies that bypass MFA), and traceless exfiltration before victims realize they've been compromised. These tools have evolved from simple keyloggers into turnkey identity harvesting systems that extract browser credentials, hardware IDs, personal documents, and cryptocurrency wallets, with stolen logs selling for as little as $10 on underground markets and Telegram channels. The harvested credentials serve as the foundation for 90% of corporate breaches, enabling initial access brokers to monetize compromised accounts through ransomware operations, financial fraud, and identity theft in an increasingly specialized cybercrime economy.
