The Klerk.ru Leak: 320 Records Exposed. Yours Might Be One.

HEROIC analysts have logged a breach affecting Klerk.ru, a Russian website in the financial category, dated March 1, 2014. The incident is recorded as a database breach affecting 320 records. The site ran on vBulletin forum software at the time, and the associated password data was stored using vBulletin's password format. Beyond these details, further specifics of the exposure are not documented in our records.

Why Even a Small Leak Like This Is Dangerous

A breach of only 320 records may look minor next to million-record mega-leaks, but scale is not the same as risk. If your account was one of the 320 affected, an attacker with your login credentials from this vBulletin database can attempt to log into your other accounts, especially if you reused the same password anywhere else. Small, overlooked leaks like this one are exactly the kind that often go unnoticed by the people affected.

What Is Known About the Klerk.ru Breach

• 320 records exposed
• Source: klerk.ru, a Russian financial-sector website
• Platform: vBulletin forum software
• Breach type: database compromise

Why This Matters

Credentials tied to a financial-sector website carry added risk, since account holders on sites like this are often assumed to have some financial literacy and, potentially, connections to accounting or tax work. Attackers use small, verified data sets like this as building blocks, layering them with other breaches to construct a fuller profile of a target for phishing, credential stuffing, or identity theft.

How a vBulletin Database Breach Happens

This incident falls into the database breach category, meaning an attacker gained direct access to the site's backend rather than tricking users individually. Older vBulletin installations were frequently targeted through known software vulnerabilities or compromised administrator accounts, allowing an attacker to export the user table, including login credentials, in a single operation.
