NEW YORK (AP) — Dozens of countries were hit with a huge cyberextortion attack Friday that locked up computers and held users’ files for ransom at a multitude of hospitals, companies and government agencies.
It was believed to the biggest attack of its kind ever recorded.
The malicious software behind the onslaught appeared to exploit a vulnerability in Microsoft Windows that was supposedly identified by the National Security Agency for its own intelligence-gathering purposes and was later leaked to the internet.
