FBI Takes Down Pro-Iran Hacker Sites Linked to Stryker Cyberattack

By Kim S. Nash

 

Hello. The Justice Department seized four websites used by hackers associated with Iran's intelligence ministry, U.S. officials said late Thursday.

Two of the sites promoted the dark-web activities of the Handala Hack Team, which claimed responsibility for a cyberattack on U.S. medical-products maker Stryker. The March 11 hack led to continuing outages in the company's manufacturing, order fulfillment and delivery systems.

“We’re grateful to the government for their efforts to seize domains linked to the purported threat actors,” Stryker said in a statement on its website. The company acknowledged that some patients have had to delay surgeries because hospitals haven’t received custom implants needed for the procedures “due to shipping delays we are experiencing.”

The seized sites had also posted calls to kill Israelis, dissidents and journalists, and claimed credit for hacks in the Middle East and elsewhere since the U.S. and Israel began bombing Iran on Feb. 28. The sites were linked to each other through Iranian IP ranges and other means, the Justice Department said.

Separately, cyber company Augur Security said several Iranian hacking groups built up their digital infrastructure in the six months leading up to the U.S.-Israeli strikes, with IP addresses traced to Russia, Estonia and the U.K.
