WASHINGTON (AP) — Microsoft says it has seized 99 websites used by Iranian hackers to launch cyberattacks.

The company said Wednesday it took control of the websites after suing the hacking group and obtaining a U.S. judge’s approval.

Microsoft says the group has tried to steal sensitive information from activists, journalists and others in the Middle East.

Microsoft calls the group Phosphorus, while others call it APT35.

Wednesday’s announcement ties the hackers to the country of Iran but not specifically to its government.

Microsoft used a similar strategy in 2016 to seize fake domains created by Russia-backed hackers.
