9,348 Plaintext Passwords From CRYPTON_LOGS 301PCS Leaked on Telegram

In December 2024, HEROIC analysts identified a stealer log dataset uploaded to a public Telegram channel by a user operating under the name CRYPTON_LOGS 301PCS. The dataset surfaced on December 19, 2024 and contained 9,348 records pulled directly from compromised endpoint devices. Each record included email addresses, plaintext passwords, and URLs representing the services and domains the stolen credentials belonged to. The plaintext nature of the passwords made this dump immediately actionable for anyone who downloaded it.

Why This Is Dangerous

When credentials are posted in plaintext to a public Telegram channel, any threat actor with access to that channel can begin using those credentials within minutes. There is no cracking required, no decryption needed. Attackers can take a list of 9,348 email and password pairs and immediately begin testing them across banking portals, email services, corporate VPNs, and social media platforms. The URLs included in this dump make it even worse -- they tell attackers exactly which services the passwords belong to, removing even the guesswork of where to try them.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (associated services and login endpoints)

Why This Matters

Stealer log dumps like CRYPTON_LOGS 301PCS fuel some of the most damaging attacks on the internet today. When attackers have a validated list of email and password combinations, they run those credentials against hundreds of other services in what is known as credential stuffing. A single compromised password that was reused across a work email and a banking account can cascade into full account takeover, identity theft, and financial fraud. Corporate employees who used work credentials on infected personal devices are at particular risk, since one infected laptop can expose an entire organization's access layer.

How Stealer Logs Work

Infostealer malware is typically delivered through phishing emails, malicious browser extentions, or trojanized software downloads. Once installed on a victims device, the malware silently harvests saved passwords from browsers, autofill data, session cookies, and any credentials typed or stored locally. This data is then exfiltrated to a command and control server operated by the attacker. From there, the stolen credentials are often packaged into "log" files and sold on dark web markets or, increasingly, distributed through Telegram channels for free or at low cost. The 301PCS in the dataset name likely refers to a batch count or package identifier used by the seller to differentiate this dump from others in the same series.

Check If You Are Affected

If any of your email addresses or passwords appeared in the CRYPTON_LOGS 301PCS dataset, you may already be at risk. HEROIC's breach database contains more than 400 billion records sourced from thousands of leaks, dumps, and dark web incidents. You can search your email address at heroic.com to see if your credentials have been exposed in this or any other known breach. If your information appears, change the affected passwords imediately and enable two-factor authentication wherever possible.
