5,257 Passwords From CRYPTON_LOGS 299PCS Surface on the Dark Web

5,257 passwords just surfaced in a stealer log batch named CRYPTON_LOGS 299PCS, uploaded to Telegram on August 12, 2024. HEROIC analysts confirmed the file pairs each plaintext password with an email address and the exact URL it logs into, all harvested from infected devices. The only way to know if you're affected is to scan your email.

Why Newly Surfaced Logins Are the Most Urgent

A password that just appeared in a fresh batch is far more likely to still be active than one from an old, well known leak, since the owner hasn't had any reason yet to change it. That window, between a file surfacing and people reacting to it, is when attackers move fastest.

What Was Exposed

• Email Addresses: confirms account ownership and gives attackers a target for phishing messages.
• Plaintext Password: fully readable, usable immediately with no cracking required.
• URLs: points directly to the login page each stolen password was captured from.

What Happens in the Hours After a Leak Like This

Automated tools typically start testing fresh batches like this one within hours, checking each pair against popular sites to see what still works. A successful match can lead to account takeover, unauthorized purchases, or an attacker using the account to reach real contacts.

How a Fresh Batch Like CRYPTON_LOGS 299PCS Appears

Stealer malware sits quietly on an infected device, copying saved browser passwords and login pages as people use them, then sends that data back to the attacker's server. Numbered batches like this 299 piece set get released as new infections keep feeding the same operation.

Is Your Login One of the 5,257 in CRYPTON_LOGS 299PCS?

Scan the device you normally log in from for malware first, since the infection behind this batch could still be collecting new passwords. Once it's clean, scan your email and change any exposed passwords from that clean device. This applies to personal and work logins alike.
