Hunt.io Attributes 14,530 Dahua Device Compromises to Operation CameraSwarm

Summary
Hunt.io says Operation CameraSwarm compromised 14,530+ Dahua devices using credential attacks, two authentication-bypass flaws and P2P relays. Public sources support the underlying mechanisms but do not independently verify the campaign totals.
Key points
- Hunt.io attributes more than 14,530 device compromises between June 17 and July 22, 2026, to the campaign; the totals remain unverified independently.
- Hunt.io reports 12,324 IP addresses across 13,229 credential-attack records, 1,923 cameras reached using CVE-2021-33044 and CVE-2021-33045, and 283 reached through P2P.
- The two authentication-bypass vulnerabilities remain listed in CISA’s KEV catalog as of August 19, 2026; Dahua advises installing fixed software or newer firmware.
- A Dahua serial number could reportedly establish an Easy4IP relay path to devices behind NAT on firmware predating mid-2024; device-level authentication may still be required.
- Hunt.io says recovered operator code recorded 89.4% of live serial numbers returning an open channel without authentication; that campaign-specific figure has not been independently reproduced.
- Researchers described the operator as Russian-speaking based on language artifacts, but did not attribute the activity to a named threat actor or government.
- Defenders are advised to update firmware, disable unnecessary P2P, use strong unique credentials, remove unused accounts and segment surveillance systems.
Article Details
- Event Type
- Reported campaign compromising Dahua devices through credential attacks, authentication-bypass vulnerabilities, and P2P relay abuse.
- Impact
- Hunt.io attributes more than 14,530 device compromises to the campaign: 12,324 unique IP addresses across 13,229 credential-attack records, 1,923 cameras reached through CVE-2021-33044 and CVE-2021-33045, and 283 devices reached through the P2P path, including devices behind NAT. Hunt.io's campaign totals and related claims have not been independently confirmed. The activity could expose cameras and network video recorders to unauthorized access; recommended mitigations include applying fixed firmware, disabling unnecessary P2P access, and securing credentials and accounts.
