The UK blogger who discovered a ‘kill switch’ that has slowed the spread of a virus wreaking havoc across the globe has revealed that the world is facing a fresh cyber attack from malicious hackers who are trying to sabotage the fix.
The 22-year-old ‘accidental hero’ – who lives at home in the south of England with his mother and father – spotted a loophole in the code that meant he could block the virus.
He says he inadvertently halted the ransomware just hours after hearing news of a cyber attack on the NHS while out for lunch with a friend while on a week off from his job at an information security company.
But speaking exclusively to MailOnline, the anonymous computer security expert revealed that cyber attackers are working to bring down the ’emergency stop’ which is halting the virus from spreading in a bid to infect millions more across the globe.
He said: ‘We’ve actually been getting attacks today – we don’t think it’s the actual group who were spreading the malware but another group is trying to attack us so the infections resume.

The softly-spoken cyber expert, who goes by the username MalwareTechBlog online, continued: ‘Obviously they haven’t actually been successful, but had they been that would actually be quite a serious thing and it wouldn’t really be something to laugh about.’
The security worker spent £8 registering the domain name the virus tries to connect with when it infects a new computer and pointed it at a ‘sinkhole server’ in Los Angeles.
It caused the malicious software to enact an ’emergency stop’, immediately halting its spread – but at first the cyber expert feared he had actually made the virus epidemic worse.
Speaking of the moment he stopped the virus, the anti-malware expert told MailOnline: ‘It should have been really nice but someone had made a mistake and told me that our registering of the domain actually caused the infection.
‘When I found out that it was actually the opposite it was more a relief.
‘Rather than a feeling of ‘yes, we’ve done this’ – it was like ‘oh god, I haven’t f***** up the world, so that’s really great’.’
