New cyber chaos appears to have been avoided: Europol

It encrypted users’ computer files and displayed a message demanding anywhere from $300 to $600 to release them; failure to pay would leave the data mangled and likely beyond fix. The infection encrypts the records and blocks use of computer files.

MalwareTech, who works for cybersecurity firm Kryptos Logic, is part of a large global cybersecurity community who are constantly watching for attacks and working together to stop or prevent them, often sharing information via Twitter.

The result paralyzed the computers of massive organizations across the globe and demanded an unlocking ransom of $300 in bitcoins. “This is just another example of the extraordinary lengths all of you go to every day to keep our country healthy”, he told the crowd at the Royal College of Nursing. Instead of having to develop their own arsenals of cyberweapons, they simply had to repurpose work done by the highly skilled cyber experts at the NSA, said Phillip Hallam-Baker, principal scientist at the cybersecurity firm Comodo. The tool was one of many linked to the NSA that were leaked online past year, then finally decrypted in April for use by anyone with the requisite coding skills. The NSA does not publicly discuss its activities. Oorth said that it was likely that many IT departments updated their systems over the weekend, patching the flaw which allowed this ransomware to spread.

According to the company, “customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March”. The British Home Secretary said most of the NHS systems were back to normal by midday Saturday.

The cross-border police agency Europol said the situation was now stable, defusing concerns that attacks that struck computers in British hospital wards, European vehicle factories and Russian banks would spread further at the start of the working week.

In Russia, government agencies insisted that all attacks had been resolved.

Europol said on Monday it was continuing to hunt for the culprits behind the unprecedented attack.

While there appears to have been some success in halting the impact of WannaCry, the vulnerability remains, and if those new variations get traction, we’ll see additional waves of computer attacks. Some patients have had their appointments cancelled or have been unable to schedule a new appointment.

Monday was the first big test for Asia, where offices had already mostly been closed for the weekend before the attack first arrived.

Hunt told broadcaster Sky News, the United Kingdom had “never seen a ransomware attack on this scale”.

Chinese media said the attack affected 29,372 organizations as well as hundreds of thousands of electronic devices. Hospitals, train stations, mail delivery and other government services were also reportedly affected.

The Japan Computer Emergency Response Team Coordination Center, a nonprofit group, said 2,000 computers at 600 locations in Japan were affected. Hitachi said it believed the difficulties are linked to the global cyberattack but they haven’t so far harmed its business operations. In Indonesia, the ransomware locked patient files on computers in two hospitals in the capital, Jakarta, causing delays. The criminals behind the attack have not yet been identified.

Tom Bossert is a homeland security adviser to U.S. President Donald Trump.

Wainwright described the cyberattack as an “escalating threat”.
