Breach Summary

In May 2025, a coalition of law-enforcement agencies (via Europols Operation Endgame) disrupted infrastructure behind Bumblebee, Latrodectus, Qakbot, DanaBot, Trickbot, and WarmCookie.

About Operation Endgame 2.0

Operation Endgame 2.0 is a 2025 international law-enforcement action against malware/botnet infrastructure; this record is the corpus of victim credentials recovered during that operation, not a breach of a single organization.

Why They Hold Your Data

Seized victim datasets from malware takedowns contain compromised identity, device, credential, and infection-linked records gathered during law-enforcement disruption operations.

Data Points Exposed

2 verified field types
Email Address
Password High

Breach Impact

Because these are credentials captured by malware on infected devices, many were valid at time of theft; presence typically indicates a device was infected rather than a single site being breached.

Exploitation & Downstream Threats

• Credential stuffing against reused passwords across other platforms | • Targeted phishing campaigns using exposed email addresses

Principal Risk Advisory

What this means for a principal

A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.

What You Should Do

  1. Reset any reused passwords and enable MFA on email first, then financial accounts.
  2. Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.

How ObscureIQ Can Help

  1. Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
  2. Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
  3. ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
