The SolarWinds hack has hit the US Department of Justice, according to a report Wednesday from The Wall Street Journal, making the agency the latest to suffer an intrusion in a far-reaching set of breaches. Hackers were reportedly able to access department emails, and about 3% of email accounts were affected, but classified systems were not accessed.

The hacking effort, which US intelligence agencies said Tuesday likely originated in Russia, has hit both federal agencies and private businesses, all of which were customers of IT software provider SolarWinds. Russia has denied involvement in the hack. The Justice Department didn’t immediately respond to a request for comment.
