Iranian hackers working to penetrate systems, businesses and governments around the world have caused hundreds of millions of dollars in damages, a report said on Wednesday.
Researchers for tech giant Microsoft said the attackers stole secrets and wiped data from computer networks after targeting thousands of people at some 200 companies over the past two years, according to The Wall Street Journal. Microsoft did not immediately respond to a query on the report.
The Journal said Microsoft traced the attacks to Holmium, a group linked to Iran, and that some of the hacking was done for Holmium by another Iranian group known as APT33.
John Lambert, the head of Microsoft’s Threat Intelligence Center, told the newspaper that the attacks were “massively destabilising events”.
The report said the hackers notably targeted oil-and-gas companies, heavy-machinery manufacturers and international conglomerates in Saudi Arabia, Germany, Britain, India and the United States.
In 2017, the security firm FireEye blamed APT33 for destructive malware that targeted organisations in West Asia and elsewhere.
The news comes with Iran, according to security experts, seeking to step up its cybercapabilities amid increasing efforts by the United States to isolate the Islamic regime.
