CRYPTON_LOGS 2.0 Was Collected Months Ago. The 4,767 Plaintext Passwords Just Hit Telegram.

HEROIC analysts identified the CRYPTON_LOGS 2.0 249PCS dataset when it surfaced on a public Telegram channel in April 2024. The log file contained 4,767 records harvested from compromised endpoints by infostealer malware. Each record included raw email addresses, plaintext passwords, and the URLs of targeted services. Unlike breaches that expose hashed credentials, this leak gave threat actors immediate, ready-to-use login data with zero additional processing required.

Why This Stealer Log Is Especially Dangerous

Most credential leaks require attackers to crack hashed passwords before they can be used. CRYPTON_LOGS 2.0 skipped that step entirely. Every password in this dataset was captured in plaintext by the infostealer malware before any encryption could be applied. That means the moment this file was uploaded to Telegram, every recieve-and-use cycle for credential stuffing attacks began instantly. Attackers do not need special tools or computing power to exploit this data.

What Was Exposed

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

Why This Matters

Stealer logs like CRYPTON_LOGS 2.0 are traded and redistributed rapidly across Telegram channels and underground forums. A dataset uploaded in April 2024 does not expire. Threat actors archive these logs and run credential stuffing campaigns against banking portals, email providers, corporate VPNs, and cloud platforms months or even years after the original upload. If your credentials occured in this log, they remain at risk today. Password reuse across services compounds the danger significantly, since one compromised account can unlock several others.

How Stealer Log Attacks Work

Infostealer malware is typically delivered through phishing emails, malicious downloads, or trojanized software installers. Once installed on a victim's device, the malware silently captures keystrokes, harvests saved browser credentials, and records session cookies. It then packages this data into a structured log file and exfiltrates it to a remote server controlled by the attacker. These logs are then bundled, often in collections labeled with piece counts like "249PCS," and distributed on platforms like Telegram where other threat actors pay for access or recieve them freely. The seperate stages of infection, collection, and distribution make these attacks difficult to detect until the data is already circulating.
