abis.pl

The investigation team has indexed a data breach connected to abis.pl, a Polish web domain, involving roughly 557,000 records. According to our investigation team, the dataset contains about 557,279 rows, including approximately 557,279 email addresses and 557,264 passwords. The estimated attack date is January 1, 2020, though this is an estimate and the exact timing of the original compromise has not been confirmed. No individual or group has claimed responsibility for the breach, and the listing was added to our database on December 1, 2024, which may reflect when the data surfaced rather than when it was taken.

Limited public reporting: As of September 25, 2026, detailed company notices or major news coverage for this listing were limited in sources reviewed. The facts below rely primarily on the indexed fields plus any secondary sources cited.

What Information Was Compromised?

Our analysis found the following data types in this breach: email addresses and passwords.

Not every individual is affected by every type of data listed here.

The presence of both email addresses and passwords in plain paired form is what makes this dataset useful to attackers. If the passwords were stored as hashes rather than readable text, that would reduce immediate risk, but our catalog does not confirm the password storage format, so affected users should assume exposure is possible.

What Are the Potential Risks for Affected Individuals?

The main risk from a breach like this is credential stuffing. Attackers take leaked email and password pairs and replay them against other websites, banking on the fact that many people reuse the same password across accounts. If you used the same password on abis.pl and on an email account, social media profile, or online banking service, those accounts could be at risk.

Leaked email addresses are also used directly for phishing. Someone who knows your email address and that you had an account on a breached service can craft convincing messages, for example claiming your account needs verification, to trick you into revealing more credentials or personal details. Because the breach dates back to 2020 by our estimate, some of the exposed passwords may have already circulated in criminal communities for years, even if you are only learning of it now.

What Should You Do If You Were Affected?

If you had an account with abis.pl, take these steps:

Change your password for the abis.pl account, if the service is still active, and for any other account where you used the same or a similar password.

Prioritize your primary email account. If someone gains control of it, they can reset passwords for nearly every other service you use. Turn on two-factor authentication there first.

Enable two-factor authentication on your other important accounts, especially banking, shopping, and social media.

Watch for phishing. Be cautious with emails that reference abis.pl or ask you to log in, reset a password, or confirm account details through a link. Go directly to the website by typing its address instead of clicking links.

Because no company response has been verified for this listing, users should not wait for an official notice before securing their accounts. Taking these precautions now is the most reliable way to limit the damage from this exposure.
