Hackers Compromised 14,500+ Dahua Devices Using Credential Attacks, Auth Bypasses, and P2P

Hunt.io disclosed Operation CameraSwarm, compromising 14,500+ Dahua cameras via credential attacks, auth bypass CVEs, and P2P relay techniques across Ukraine and Russia.

Hunt.io reconstructed a campaign codenamed Operation CameraSwarm that compromised over 14,530 Dahua devices between June 17 and July 22, 2026. Attack paths included credential attacks against 12,324 IPs, exploitation of CVE-2021-33044 and CVE-2021-33045 affecting 1,923 cameras, and P2P relay access to 283 devices behind NAT. The operator, assessed as Russian-speaking, left behind 2,616 files including tooling and campaign logs, with confirmed compromises concentrated in Ukraine and Russia. Dahua advises factory resets and firmware updates; both 2021 CVEs remain in CISA's KEV catalog.

ExfilSquad Targets New Victims, Shares Data via Torrents

Extortion group ExfilSquad lists 13 new US, UK and Swedish victims and now distributes stolen data via peer-to-peer torrents.

ExfilSquad, a data-theft extortion collective that emerged in mid-2026, announced 13 new victims in the US, UK and Sweden with an August 5, 2026 negotiation deadline. The group skips ransomware, instead stealing data and threatening publication on a dark web leak site. Resecurity says its TTPs center on exploiting misconfigured Microsoft Dataverse, Power Pages, case management and CRM portals. The group now distributes stolen data through per-victim torrent trackers and web seeds, making leaks hard to contain.

Inside Operation CameraSwarm: How One Actor Took Over 14,000 Dahua Cameras

One actor compromised over 14,000 Dahua cameras in Ukraine and Russia using brute-force, authentication bypass, and cloud relay serial-number abuse.

Hunt.io reconstructed Operation CameraSwarm from an exposed operator directory, revealing one actor compromised 14,000+ Dahua cameras between June 17 and July 22, 2026, mainly in Ukraine and Russia. The toolkit included a brute-force engine, a two-flaw 2021 authentication-bypass chain planting a persistent backdoor account on 1,923 cameras, and abuse of Dahua's cloud relay where 89.4% of probed serials returned open, unauthenticated channels. A SalatStealer Windows binary and Defender-disabling PowerShell script were staged on the same server but appear unrelated to the camera campaign.
