Infected computers
Abu Dhabi - Emirates Voice

Technical staff scrambled on Sunday to patch computers and restore infected ones, amid fears that the ransomware worm that stopped car factories, hospitals, shops and schools could wreak fresh havoc on Monday when employees log back on. Experts said the spread of the virus dubbed WannaCry had slowed, but the respite might only be brief.

"Expect to hear a lot more about this tomorrow (Monday) morning when users are back in their offices, said Christian Karam, a Singapore-based security researcher.

New versions of the worm are expected, they said, and the extent of the damage from Friday's attack remains unclear.

Infected computers appear to largely be out-of-date devices that organisations deemed not worth the price of upgrading or, in some cases, machines involved in manufacturing or hospital functions that proved too difficult to patch without possibly disrupting crucial operations, security experts said.

Marin Ivezic, cybersecurity partner at PwC, said that some clients had been "working around the clock since the story broke" to restore systems and install software updates, or patches, or restore systems from backups.

Microsoft released patches last month and on Friday to fix a vulnerability that allowed the worm to spread across networks, a rare and powerful feature that caused infections to surge on Friday.

Code for exploiting that bug, which is known as "Eternal Blue," was released on the internet in March by a hacking group known as the Shadow Brokers. The group claimed it was stolen from a repository of National Security Agency hacking tools. The agency has not responded to requests for comment.

Hong Kong-based Ivezic said that the ransomware was forcing some more "mature" clients affected by the worm to abandon their usual cautious testing of patches "to do unscheduled downtime and urgent patching, which is causing some inconvenience." He declined to identify which clients had been affected.

The head of the European Union police agency said on Sunday the cyber assault hit 200,000 victims in at least 150 countries and that number will grow when people return to work on Monday.

"The global reach is unprecedented ... and those victims, many of those will be businesses, including large corporations," Europol Director Rob Wainwright told Britain's ITV. "At the moment, we are in the face of an escalating threat. The numbers are going up, I am worried about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning."
