The massive “ransomware” attacks unleashed Friday, May 12th, were slowed down, computer experts said, over the weekend after a researcher found a kill switch hidden in the computer worm. But that researcher and other experts say they expect that hackers will release—or have already unleashed—an updated version of that worm without a kill switch.
The attacks, which made over 200,000 victims in at least 150 countries, affect only computers running Microsoft Corp.’s Windows that haven’t installed the security patch that the company released in March, or the emergency patch it released for older Windows systems over the weekend.
Steve Ranger, security expert for ZDNet, warns that the second wave of the WannaCrypt (popularly called"WannaCry) ransomware attack could arrive this week, and that you should prepare now to protect your business.
He says that this this particular attack is without parallel, largely because the ransomware was combined with a worm-like functionality that allowed the infection to spread rapidly from PC to PC.
Many Windows XP systems were unprotected and Microsoft is now taking what it describes as a “highly unusual” step to provide public patches for Windows operating systems that are in custom support only. This includes specific fixes for Windows XP, Windows 8, and Windows Server 2003.
