The YOULOGS 703pcsMIX Dump Contains Exactly 10,101 Email and Password Pairs

On October 13th, 2023, a file labeled "YOULOGS 703pcsMIX" was uploaded to a public Telegram channel by an anonymous user. Security researchers monitoring dark web and messaging platform activity flagged the file as a stealer log containing exactly 10,101 records. Each record in the dump linked an email address to a plaintext password and a URL, giving whoever downloaded the file an immediate, ready-to-use list of login credentials. The name suggests a mixed collection pulled from hundreds of compromised devices, not a single company data breach. Stealer logs aggregate stolen data from many different people, which means victims in this dump could be users of completely different services and platforms.

Why This Is Dangerous

There is no encryption to bypass and no hashing to reverse. Every password in the YOULOGS 703pcsMIX dump is in plaintext, meaning attackers can start using these credentials the moment they open the file. Automated tools can take the entire list and test each email and password combination across hundreds of websites simultaneously. If someone in this dump reuses the same password for their bank, their email, or their employer's systems, all of those accounts are now at risk. The data has been sitting on Telegram since October 2023, meaning it has had well over a year for cybercriminals to download, redistribute, and exploit it. Many of these credentials have likely already been used in atackes that victims may not have even noticed yet.

What Was Exposed in the YOULOGS 703pcsMIX Dump

• Email addresses
• Plaintext passwords (no encryption, usable as-is)
• URLs of websites and services where credentials were captured

Why This Matters

A dump of 10,101 plaintext email and password pairs is not a minor inconvenience. For each person in this list, their account security depends entirely on whether they have changed that password since the dump was made. If they have not, those credentials are still valid and still usable. Attackers use this kind of data to take over email accounts, access financial services, commit identity fraud, and in cases where corporate email addresses are involved, gain footholds inside company networks. The presence of URL data also tells attackers exactly which service each credential belongs to, removing any guesswork and making the exploit process faster and more targeted.

How Stealer Log Breaches Work

Stealer logs are created by infostealer malware, programs that get onto a victim's device through a phishing link, a malicious attachment, or a fake software installer. Once running, the malware silently harvests saved passwords from browsers, stored credentials from apps, and session cookies from active logins. It then sends all of that back to whoever deployed the malware. Attackers collect logs from many infected devices and bundle them together into files like YOULOGS 703pcsMIX. These bundles are then sold, traded, or shared freely on dark web markets and Telegram channels. Victims typically have no idear anything has happened until they notice their accounts behaving strangely.

Check If You Are Affected

HEROIC's free dark web scanner searches over 400 billion compromised records, including stealer logs like the YOULOGS 703pcsMIX dump. Enter your email address to see if your credentials have been exposed. If you appear in this or any other breach, changing your passwords immediately and enabling two-factor authentication on your accounts can stop attackers from using stolen credentials against you.
