'Accidental hero' finds kill switch to stop spread of ransomware cyber-attack...
The “accidental hero” who halted the global spread of an unprecedented ransomware attack by registering a garbled domain name hidden in the malware has warned the attack could be rebooted.
https://www.theguardian.com/technol...tch-to-stop-spread-of-ransomware-cyber-attackThe kill switch was hardcoded into the malware in case the creator wanted to stop it spreading. This involved a very long nonsensical domain name that the malware makes a request to – just as if it was looking up any website – and if the request comes back and shows that the domain is live, the kill switch takes effect and the malware stops spreading. The domain cost $10.69 and was immediately registering thousands of connections every second.
