What is WannaCry? What does WannaCry ransomware do?


“The Ransomware virus is a virus that affects computer systems and locks up the files on your computer and encrypts them in a way that you can not access them anymore”, said Harinder Singh Sekhon, in-charge, cyber cell.

Instead of developing hacking tools in secret and holding them for use against adversaries, governments and intelligence agencies should share weaknesses they find with Microsoft and other software makers so that vulnerabilities can be repaired. He added, “Ransomware is a programme that gets into your computer only by downloading and it will ask you to pay ransom in Bitcoins”.

However, if you do pay, you’re only fueling the fire. WannaCry demands users pay $300 to essentially get their computer – and data – back from being held hostage.

The vulnerability in the Microsoft Windows software – exploited by “WannaCrypt” – crippled computers across 150 countries, with hackers demanding hundreds of dollars from the users for them to regain control over their data.

What versions of Windows are affected?

The bank said the attack, which exploited “a flaw” in the Windows operating system, illustrates just how many businesses have delayed upgrading their operating systems to Windows 10. “To protect your computer from such malicious malwares, one should be aware of the security measures and install all necessary updates”, Dinesh Yadav, superintendent of police (city), said in a press note. Microsoft also took the unusual step of releasing security fixes for systems it no longer is keeping up to date, including the Windows XP, first released in 2001 and still widely used in some corners.

Nash said he’s glad he insisted his few dozen area clients upgrade their respective operating systems from Windows XP, including the last to do so about a year ago. Security Update KB401258 protects vulnerable Windows and Windows Server editions, including Windows 8, Vista, XP and Windows Server 2003 and 2008.

Still, since the attack has making headlines, the Internet is full of organizations and people providing guidance about safe use of technology. Digital Marketing consultant/ Director of Androguru, Nigel Quadros says: “The best thing to do is keep your Windows system updated and turn on the auto updates”.

The No More Ransom site offers several tips for dealing with – or potentially dealing with – ransomware. This will make it much easier to spot potentially malicious files.
