Cyber security experts are expecting another wave of computer-system attacks that encrypt files and demand ransom to unlock them on Monday, as companies and government agencies are seeking to restore normal operations and figure out the roots of the attack.
The massive “ransomware” attacks unleashed Friday were slowed down, computer experts said, over the weekend after a 22-year-old British 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.
The problem is that it can take organizations, especially large ones, a long time to install these patches. “I think there’s going to be a lot of infections Monday morning,” said Ofer Israeli, chief executive of Tel Aviv-based cyber security firm Illusive Networks. “Time will tell how quickly people are going to patch their systems.”
