OJS_Valid Leak Exposed 4 Logins – Check Your Email Now

On 23-Apr-2026, a stealer log named OJS_Valid was uploaded to a Telegram channel by an anonymous user. It is one of the smallest logs HEROIC has tracked, just 4 records, but each entry includes a full email address, a plaintext password, and the URL of the site that password unlocks.

Don't Let the Small Number Fool You

Four records is a small file by stealer log standards, but that does not make it any less real for the people in it. If one of those four accounts is yours, the exposure is just as complete as it would be in a much larger breach. The passwords in this log are stored in plaintext, so whoever has the file can use them to log in right away, without needing to crack or guess anything.

What Was Exposed in the OJS_Valid Log

• Email addresses
• Plaintext passwords
• URLs of the websites and services those passwords unlock

Each of the 4 entries connects a working password to the exact site it opens, giving anyone who has the file a direct route into that account.

Why It's Worth Checking, Even for Just 4 Accounts

Small stealer logs like this one still get copied, traded, and tested by automated tools, which creates real consequences:

• Credential stuffing: attackers try the leaked email and password on other sites, betting on reused logins.
• Account takeover: since the exact login URL is included, someone can go straight to the account and sign in.
• Identity theft: access to an email inbox can lead to password resets across other services.
• Financial fraud: if the linked site touches payment or banking information, a stolen login can lead to direct financial loss.

How a Log Like OJS_Valid Gets Created

Stealer malware typically spreads through cracked software, pirated games, or fake downloads. Once it lands on a device, it quietly scans the browser for saved logins, capturing usernames, passwords, and the exact web addresses they were entered on. That data is sent back to whoever controls the malware, packaged into a file, and shared or sold, in this case through a small Telegram upload covering just 4 accounts.
