Entity: Qakbot · Actor: Qakbot (malware operators) · Sources: 2 references
Attack: Malware / Infostealer
Profile: Malware / Botnet · Banking malware and botnet operations · Malware botnet infrastructure · Global
Timeline: Breach (2023-08-29) · Indexed (Aug 29, 2023) · Year (2023)
Exposure: 6.4M records · 2 fields: Email Address, Password
Status: Compilation
Executive Summary
This record represents roughly 6.4 million credential pairs that the Qakbot malware stole from victims and that law enforcement recovered during the August 2023 Operation Duck Hunt takedown. The recovered data, shared with HIBP, consists of email addresses and passwords harvested from infected machines. It is a compilation of malware-stolen victim credentials, not a breach of a single organization.
ObscureIQ assessment: Presence in this set indicates a device was infected with Qakbot and its stored/typed credentials were captured, so exposure extends to any credential entered on that device, not just one service.
Breach Impact
Because these are live credentials captured by an infostealer, many were valid at time of theft, creating direct account-takeover risk across whatever services victims used them on until reset.
About Qakbot
Qakbot (also known as Qbot) was a long-running malware and botnet operation used to steal credentials and deploy ransomware across hundreds of thousands of infected computers worldwide.
Why They Hold Your Data
Malware botnet infrastructure typically accumulates stolen credentials, infected device identifiers, system metadata, browser data, email-related information, and command-and-control telemetry needed to manage compromised machines and monetize access. Its workflows generate data through infection, credential capture, device profiling, and centralized collection from large numbers of endpoints.
Recent Developments
In August 2023, the FBI-led Operation Duck Hunt disrupted Qakbot, seized infrastructure and cryptocurrency, and recovered stolen credentials that were shared with Have I Been Pwned and a Dutch police "Check Your Hack" portal.
