Critical takeover vulnerabilities in 92,000 D-Link devices under active exploitation

Hackers are actively exploiting a pair of recently discovered vulnerabilities to remotely commandeer network-attached storage devices manufactured by D-Link, researchers said Monday.

Roughly 92,000 devices are vulnerable to the remote takeover exploits, which can be remotely transmitted by sending malicious commands through simple HTTP traffic. The vulnerability came to light two weeks ago. The researcher said they were making the threat public because D-Link said it had no plans to patch the vulnerabilities, which are present only in end-of-life devices, meaning they are no longer supported by the manufacturer.

On Monday, researchers said their sensors began detecting active attempts to exploit the vulnerabilities starting over the weekend. Greynoise, one of the organizations reporting the in-the-wild exploitation, said in an email that the activity began around 02:17 UTC on Sunday. The attacks attempted to download and install one of several pieces of malware on vulnerable devices depending on their specific hardware profile. One such piece of malware is flagged under various names by 40 endpoint protection services. Security organization Shadowserver has also reported seeing scanning or exploits from multiple IP addresses but didn’t provide additional details.
