wannacry ransomware

Ransomware is back this week and this time the attack was nothing less than spectacular affecting over 200000 users worldwide including from US, Russia, China, India and UK. No country to blame as the attack spared no one! Ransomware is a malware that locks your computer to prevent you from accessing data until you pay a ransom, usually demanded in Bitcoin. This malware is named WannaCry and the cybercrime unit of Europol says the current attack has reached an "unprecedented level." Among thousands of organizations that were affected, the prominent names include Britain's National Health Service, the U.S.-based courier FedEx, automaker Renault in France and Spain's largest telecom operator.

Top security firm are pointing blame on North Korea's infamous Lazarus Group. Kaspersky and Symantec said that based on the software trail, it points to the  government-linked North Korean hackers, who were implicated in the 2014 attack on Sony Pictures and an $81m heist on a Bangladeshi bank in 2016.

Over the weekend a “kill switch” was discovered by accident, which doesn’t stop the malware from spreading, but at least prevents it from activating the code that encrypts and ransoms your data.

Microsoft issued quick to issue a patch for old systems and also cautioned a warning that some attacks would be normal if the devices kept using legacy outdated OS software. It blamed governments for storing data on software vulnerabilities which could then be accessed by hackers.
