What caused the global 'WannaCry' ransomware attack?

Cyberattack effect: Over 2 lakh ATMs in India to be closed for software update

Called WannaCry or WannaCrypt, the ransomware program is spread by taking advantage of a Windows vulnerability that Microsoft released a security patch for in March.

Bkav recommends that all computer users immediately install updates and security patches and hotfixes via Windows Update.

"Everything seems to be normal, so far". But reports soon came in from all over the world.

"While it would be satisfying to hold accountable those responsible for this hack - something that we are working on quite seriously - the worm is in the wild, so to speak, at this point, and patching is the most important message as a result", said Bossert.

The China Daily said Wednesday that the U.S.'s National Security Agency should take some of the blame for last week's WannaCry ransomware attack, which targeted vulnerabilities in Microsoft systems and affected 30,000 Chinese organizations alone.

Security solutions providers have also accelerated efforts to develop tools to tide over the crisis.

At least one Australian business has been affected by the global "WannaCry" ransomware attack, the nation's Cyber Security Minister confirmed. They allege that last week's WannaCry attack exploited a flaw that the United States government knew about and chose not to disclose, an identical situation to the Heartbleed virus that the National Security Administration knew about for around two years before researchers discovered it and announced it to the public.

Called WannaCry or WannaCrypt, the virus has already hit 48 NHS hospitals across Britain.

The Iranians know that if they have to return to a time of sanctions , it will be detrimental to their economy. Rouhani won a commanding victory, taking more than 50 percent of the vote in the June 14 election.

"WannaCry" is infecting computers running the older versions of Microsoft Windows operating systems, locking access to files on the computer.

Malware requests payment in Bitcoins because they are safe, and can not be tracked by cyber security researchers or law enforcement agencies.

So keep your softwares updated as the the victim of ransomware are being demanded of bitcoins worth $300 and if you miss the deadlines the amount is doubled although security firms are against paying this amount and advised users not to pay.

Stock exchanges - the BSE and the NSE - have advised trading members to undertake "appropriate actions" tackle any threat from the ransomware WannaCry, which has hit computers and networks across the world.

CERT-In further said that it sent out advisory to the Reserve Bank of India on the matter, on Saturday itself.

Neither corporate nor banks have encountered any such disruptions.

The VNCERT said the ransomware is extremely unsafe as it is capable of stealing information and decrypting the entire system that has been infected.
