Wanna Cry ransomware worm hits over 200,000 computers all over the world

The weekend has been quite chaotic as far as cyber security is concerned after a ransomware worm called Wanna Cry hijacked over 200,000 computers across 150 countries.

Wanna Cry cyber attack spreads through phishing emails and on systems that are unpatched and outdated.

Officials all over the world had been trying to nab the culprits behind the Wanna Cry ransomware worm but in vain. The ransomware worm has affected operations across hospitals, schools, shops, rail and bus networks, car factories among several others by attacking computers with Microsoft Windows operating systems.

Major organizations like the UK’s National Health Service (NHS), Telefonica, Deutsche Bahn and FedEx were among those that were severely hit by the latest ransomware worm.

Wanna Cry ransomware worm has slowed down as per cyber security experts ever since it was launched on Friday, 12 May. However, officials fear that as Monday marks the restart of work at several offices, the Wanna Cry ransomware worm is likely to be activated and create massive trouble in organizations when employees return from the weekend to switch on their office computers.

Besides, new versions of Wanna Cry ransomware worm are expected even as the damage caused since the Friday’s cyber attack is yet to be assessed.

A major danger was averted after a 22-year-old cybersecurity researcher going by the identity MalwareTech activated a kill switch, which put an end to several new infections while giving time to patch computers. The kill switch came through after MalwareTech accidentally found a domain name in the Wanna Cry ransomware worm code which was not registered before.

However, the creators of the Wanna Cry ransomware worm are likely to change the code and find a way to re-enter computers. The ransomware worm is believed to have been developed using a leaked hacking tool built by the US National Security Agency dubbed as EternalBlue exploit.
