Following the recent press coverage of ‘Gameover Zeus’, the virus that the American Justice Department dubbed “One of the most sophisticated cyber threats ever”, there’s never been a better time to recap on how to keep your details safe online.
What is the Gameover Zeus Virus?
Last week, authorities around the world discovered a massive computer virus that had diverted millions of dollars away from company and personal bank accounts. Its name was ‘Gameover Zeus’ and it had been lurking in the online ether since 2011. The virus was able to infect computers when the computer’s user clicked on a link from an infected email.
Over the weekend, international crime fighting organisations joined with legal experts in Operation Tovar to address the threat. Together they have succeeded in temporarily shutting down the machines that were used to control the infected computers, so that they can’t be used to infect new computers. By now, anyone with Gameover Zeus already on their computers should have been contacted by their Internet service providers, with advice on what to do next.
The game may be over for Gameover Zeus, but this incident has highlighted how important it is to protect your computer and personal data – it’s estimated that this virus cost the world billions of pounds.
