Iranian hackers attacked hundreds of global firms over the last two years. Those targeted included Microsoft. The Wall Street Journal reported that Microsoft traced the attack against it to a group called Holmium. It had been tracking the group for 4 years. At the time of this writing, it had not been reported that Apple was a target.
The campaign, the scope of which hadn’t previously been reported, stole corporate secrets and wiped data from computers. It caused damages estimated at hundreds of millions of dollars in lost productivity and affected oil-and-gas companies, heavy-machinery manufacturers and international conglomerates in more than a half-dozen countries including Saudi Arabia, Germany, the U.K., India and the U.S., according to researchers at Microsoft, which deployed incident-response teams to some of the affected companies.
