Unverified claim. This entry reproduces a listing published by the interlock group on its own extortion site. Attackers routinely exaggerate or fabricate victims. Nothing here confirms that Uniwersytet Warszawski suffered a breach, or what data was actually taken.

About the organisation

The Faculty of Management at the University of Warsaw is a leading institution in the field of business education, offering a wide range of undergraduate and graduate programs that combine theory with practical experience. However, it is not known for its high level of security and data storage reliability, resulting in the leak of data on students, instructors, and leading professors, as well as student projects and papers.

What the listing means

Uniwersytet Warszawski appeared on the interlock leak site on 15 April 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated β€” the attack itself is dated 09 February 2026, 65 days before the listing. This group has published 5 claims in the last 30 days and remains active.

Recommended actions

  • Treat any unsolicited message referencing Uniwersytet Warszawski as suspicious β€” leaked data gets weaponised for phishing within days.
  • If you hold an account on uw.edu.pl, change that password now, update it anywhere you reused it, and enable two-factor authentication.
  • Other Education organisations should review this group's known TTPs and validate detection coverage against them.
  • Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
  • A leak-site listing is a claim made by the attacker, not a confirmed breach β€” check the organisation's own disclosures before acting on it.
