NSA Told Microsoft of Flaw Before Ransomware Attack

Hackers behind the global WannaCry ransomware attack, that has hit 150 countries since Friday, have earned about ₹55 lakh so far.

Ransomware is a type of wicked and malicious software that takes over the system of a computer.

Currently, there is no permanent fix that could end the wrath of this ransomware, but here are a few pointers that could help you in protecting your Windows PC if it has not been attacked yet. Ensuring that your Windows operating system is up to date with the most recent security and software updates, which patch any holes and vulnerabilities in the software, makes it much more hard for a hacker to infiltrate your system and networks.

Microsoft had patched the vulnerability exploited in WannaCry attacks with the March 2017 Patch Tuesday cycle, so all systems running Windows 7, Windows 8.1, and Windows 10 were already secure when the WannaCry ransomware dropped bombs on unsuspecting systems last week.

The Shadow Brokers eventually called it quits in January and disabled its online accounts, only to return in April in a surprise move that involved publishing the password for an encrypted archive containing many Linux and Windows exploits, as well as malware implants supposedly used by the Equation.

Ahead of the attack, Microsoft released a security update that fixes the exploited flaw on now supported Windows operating systems.

Ransomware actually locks down files on an infected computer and asks the computer's administrator to pay in bit coins in order to regain control of them.

What versions of Windows are affected?

No less than 80% of Indian ATMs work on Windows XP and utilises an operating system that restrains the machine's exercises to uncovered rudiments, for example, apportioning money on demand and checking the record adjust. Keep Windows Update turned on, so that you are automatically prompted to download and install these updates.

The banks predicts the attack will prompt folks to upgrade, which is a good thing for Microsoft because it will increase the number of new Office 360 Commercial subscriptions.

Most antivirus programs can scan files to see if they might contain ransomware before downloading them. The longer you wait, the more you have to pay.

The attack on Britain's NHS was potentially the most devastating as thousands of patients' appointments were cancelled, ambulances rerouted, records lost and chaos followed, despite the warnings delivered, some as recently as a year ago, on the vulnerability of outdated systems.
