A Department of Defense bulletin on a ‘leaking’ sinkhole has baffled cybersecurity experts

Posted on by

In mid-April, an obscure agency housed under the Department of Defense issued a bulletin that a little-known, Chinese-linked hacking group is likely responsible for some suspicious activity aimed at defense contractors in the U.S. But how the Defense Counterintelligence and Security Agency (DCSA) came to that conclusion is complicated. The alert, sent to 38 contractors, says DCSA detected the group was making “inbound and outbound connections” with contractors’ facilities as of Feb. 1.

Bank of America, JPMorgan Chase, and SunTrust are among the banks whose IP addresses are being spoofed to seem like they are conducting broad scans of the internet, GreyNoise said. That large-scale scanning is duping people into thinking that the IP addresses are malicious, GreyNoise founder Andrew Morris told CyberScoop. “There are a lot of people around the internet who are definitely convinced that these are bad IPs,” he said. Threat intelligence teams in the U.S. financial sector are looking into the issue, sources told CyberScoop. Morris said the volume of traffic is too low to be a distributed denial-of-service attack. Instead, he suggested, a bad […]
