Hackers Launched Global Cyberattack, Computer Infected In About 100 Countries

The Friday that passed away yesterday on 12th May 2017 was a nightmare for the security experts. A global cyber attack leveraging hacking tools widely believed by researchers to have been developed by the U.S. National Security Agency hit international shipper FedEx, disrupted Britain’s health system and infected computers in nearly 100 countries on Friday.

Hackers Launched Global Cyberattack, Computer Infected In About 100 Countries

Cyber extortionists cheated victims into opening malicious malware attachments to spam emails that appeared to contain invoices, job offers, security warnings and other legitimate files.

The ransomware encrypted data on the computers, demanding payments of $300 to $600 to restore access. Security researchers said they observed some victims paying via the digital currency bitcoin, though they did not know what percent had given in to the extortionists.

Researchers with security software maker Avast said they had observed 57,000 infections in 99 countries with Russia, Ukraine and Taiwan the top targets. The most disruptive attacks were reported in Britain, where hospitals and clinics were forced to turn away patients after losing access to computers.

International shipper FedEx Corp said some of its Windows computers were also infected. “We are implementing remediation steps as quickly as possible,” it said in a statement.

Still, only a small number of U.S.-headquartered organizations were hit because the hackers appear to have begun the campaign by targeting organizations in Europe, said Vikram Thakur, research manager with security software maker Symantec.

By the time they turned their attention to the United States, spam filters had identified the new threat and flagged the ransomware-laden emails as malicious, Thakur said.

The U.S. Department of Homeland Security said late on Friday that it was aware of reports of the ransomware, was sharing information with domestic and foreign partners and was ready to lend technical support.

Telecommunications company Telefonica was among many targets in Spain, though it said the attack was limited to some computers on an internal network and had not affected clients or services. Portugal Telecom and Telefonica Argentina both said they were also targeted.

Private security firms identified the ransomware as a new variant of “WannaCry” that had the ability to automatically spread across large networks by exploiting a known bug in Microsoft’s Windows operating system.

“Once it gets in and starts moving across the infrastructure, there is no way to stop it,” said Adam Meyers, a researcher with cyber security firm CrowdStrike.

The hackers, who have not come forward to claim responsibility or otherwise been identified, likely made it a “worm,” or self-spreading malware, by exploiting a piece of NSA code known as “Eternal Blue” that was released last month by a group known as the Shadow Brokers, researchers with several private cybersecurity firms said.

“This is one of the largest global ransomware attacks the cyber community has ever seen,” said Rich Barger, director of threat research with Splunk, one of the firms that linked WannaCry to the NSA.

Microsoft on Friday said it was pushing out automatic Windows updates to defend clients from WannaCry. It issued a patch on March 14 to protect them from Eternal Blue.

“Today our engineers added detection and protection against new malicious software known as Ransom: Win32.WannaCrypt,” Microsoft said in a statement. It said the company was working with its customers to provide additional assistance.

 

In my opinion, this global cyber attack was one of the most dangerous cyber attacks till today. Hackers are being really smart and using really great technologies these days to execute these cyber attacks you to defence against these attacks you guys have to be smart and aware of what is going on in the cyber world and that’s what we are supplying here on Legit Tech Info.
