According to a new joint report issued by the US Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI), hackers have been penetrating the computer networks of companies that operate nuclear power stations, energy facilities, and manufacturing plants in the US since May 2017. The joint report carried an urgent amber warning, which is the second-highest rating for the sensitivity of a threat. The report was publicized by the New York Times last week.

According to the report, an "advanced persistent threat" actor was responsible for the attacks, which has included thus far:

  • Hackers writing targeted email messages containing fake resumes for control engineering jobs and then sending them to senior industrial control engineers who have access to critical industrial control systems. The resumes were Microsoft Word documents that contained malicious code. Once the recipient clicks on the document, the attackers copy the recipient's credentials and access the network.
  • Hackers compromising websites they know their victims visit (watering hole attack).
  • Hackers redirecting the victims' internet traffic through their own machines (man-in-the-middle attack).

The report does not say whether the cyber intrusions are an attempt at espionage, or part of a plan to cause physical damage. Nor is there any indication as to how many facilities were compromised. The report does state, however, that the hackers appear to be mapping out computer networks for future attacks.

In a joint statement issued by the DHS and FBI, a spokesperson for the DHS said "There is no indication of a threat to public safety, as any potential impact appears to be limited to administrative and business networks." John Keeley, a spokesperson for the Nuclear Energy Institute (which works with the 99 utilities that operate nuclear plans in the US), said nuclear facilities are required to report cyber attacks that relate to their safety, security and operations. None have reported any cyber attacks thus far.

On May 11, as the attacks were ongoing, President Trump signed an executive order to strengthen the cybersecurity of federal networks and critical infrastructure.
