A Chinese state-sponsored hacking group has been observed while attempting to exploit the Windows Zerologon vulnerability in attacks against Japanese companies. The attacks were discovered by Symantec researchers after the detection of suspicious DLL side-loading activity on a customer’s network. The companies hit are, in the main, large, well-known organizations, many of which have links to Japan or Japanese companies, which is one of the main factors tying the victims together. The APT10 hackers have been running this campaign for roughly an entire year.
