Friday’s unprecedented ransomware attack may have stopped spreading to new machines — at least briefly — thanks to a “kill switch” that a security researcher has activated.

The ransomware, called Wana Decryptor or WannaCry, has been found infecting machines across the globe. It works by exploiting a Windows vulnerability that the U.S. National Security Agency may have used for spying.

The malware encrypts data on a PC and shows users a note demanding $300 in bitcoin to have their data decrypted. Images of the ransom note have been circulating on Twitter. Security experts have detected tens of thousands of attacks, apparently spreading over LANs and the internet like a computer worm.

A Microsoft manager this week offered IT administrators a way to replicate — in a fashion — the security bulletins the company discarded last month.

“If you want a report summarizing today’s #MSRC security bulletins, here’s a script that uses the MSRC Portal API,” John Lambert, general manager of the Microsoft Threat Intelligence Center, said in a Tuesday message on Twitter.

Lambert’s tweet linked to code depository GitHub, where he posted a PowerShell script that polled data using a new API (application programming interface). Microsoft made the API available in November when it first announced that it planned to axe the security bulletins it had issued since at least 1998.
