WASHINGTON (AP) β€” A new report says an unusual strain of ransomware is leading a new generation of malicious software that hackers use to exploit computer server vulnerabilities.

The report Monday by Cisco Systems Inc.'s Talos security research group describes how virus-like software known as "samsam" works. It worms its way through networks without requiring someone to click a link to open an infected attachment.
