The EpilepsyLogsOwner Breach Gave Hackers Everything They Need to Drain Your Accounts

In July 2025, HEROIC analysts identified a stealer log file uploaded to Telegram by a threat actor using the handle EpilepsyLogsOwner. The specific file, labeled 364count, contained 17,815 records harvested from infected devices. Exposed data includes email adresses, plaintext passwords, and the URLs of every website and API host those compromised machines were communicating with. That combination puts attackers in a precise position to target each victim's most sensitive accounts.

Why This Is Dangerous

Most credential dumps leave attackers guessing which services a victim actually uses. This stealer log does not. The URLs captured alongside each password tell a criminal exactly which banking sites, email platforms, cloud services, and workplace tools the victim was authenticated to at the moment of infection. That specificity converts a generic credential list into a personalized roadmap for account takeover, with no guesswork required and no wasted attempts on services the victim does not use.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (website endpoints and API hosts)

Why This Matters

With plaintext passwords and matching service URLs in hand, attackers can move immediately. Credential stuffing tools test each stolen login against the specific platforms named in the log, achieving far higher success rates than conventional brute force attacks. For victims who reuse passwords, a single record can unlock email, banking, cloud storage, and social media simultaneously. The downstream risks include account takeover, fraudlent transactions, identity theft, and in workplace contexts, corporate network compromise that extends well beyond the original victim.

How Stealer Logs Work

A stealer log is generated by infostealer malware, a category of malicious software designed specifically to silently harvest credentials from infected devices. It typically reaches a victim through a phishing email, a fake software download, or a malicious browser extention. Once running, it sweeps through saved browser passwords, active session cookies, autofill entries, and network connection records. Everything is packaged into a structured file and transmitted back to the attacker, who then distributes it through Telegram channels or underground markets. The EpilepsyLogsOwner collection is part of a 364-count series, meaning this single handle was responsible for hundreds of similar dumps circulatng across criminal networks.
