Grey Noise Observes 3X Surge in Exploitation Attempts Against TVT DVRs — Likely Mirai
Summary: GreyNoise observed exploitation attempts against TVT NVMS9000 DVRs at three times typical activity, beginning March 31, 2025 and peaking on April 3 at over 2,500 unique IPs, with more than 6,600 IPs attempting exploitation in the past 30 days. GreyNoise identified sufficient overlap with Mirai to associate the activity with the botnet, and said the information disclosure flaw can be used to gain administrative control over affected systems.
Key Takeaway: The DVRs are used in security and surveillance systems, and the top target countries are the United States, United Kingdom, and Germany, with most attacking IPs originating from the Asia-Pacific region.
