Europol: Have I Been Pwned’s Post

Operation Endgame Expands: Europol Adds 131K Email Addresses in Latest Data Breach Wave

Europol has released an additional 131,000 email addresses as part of the fourth wave of Operation Endgame, a large-scale cybersecurity crackdown targeting malware and botnet infrastructure. The new dataset, published today, overlaps with existing breach records 36% of the exposed emails were already documented in the Have I Been Pwned database.

Operation Endgame, a coordinated effort involving law enforcement agencies across multiple countries, aims to disrupt cybercriminal operations by seizing infrastructure, arresting threat actors, and exposing compromised credentials. This latest update follows prior disclosures, reinforcing the campaign’s ongoing impact on cybercrime networks.

The breach data, now publicly accessible, highlights the persistent risk of credential reuse and the scale of cybercriminal targeting. Europol’s continued releases serve as a resource for security teams to identify and mitigate exposure within affected organizations.
