How to Shield Your System Against WannaCry Ransomware Attack

He added that the rate of infection has slowed over the weekend. And the software is already inspiring imitators, as the Bleeping Computer site reports.

Avivah Litan, a cybersecurity analyst at Gartner, agreed that the government is "is negligent not doing a better job protecting companies", but added that it's not like "you can stop the US government from developing cybertools" that then work as intended. Still, he said, "Microsoft needs to admit that the 20th century is over, it's a much more hostile environment, and that hobbling the NSA won't make us any safer". Human error is the number one reason for the success of an email scam, so educating staff to stay on top of their email behavior is key.

Malware requests payment in Bitcoins because they are safe, and can not be tracked by cyber security researchers or law enforcement agencies. "They've been able to manage through it".

Use firewalls, and anti-virus software from reputed vendors, and ensure these are upgraded regularly. The initial attack had started after many offices had closed Friday. NIC is monitoring more than 100 websites of state departments, institutions and colleges.

A report by worldwide cybersecurity firm Symantec in April 2017 found India was among the most heavily-infected countries, with four per cent (or over 18,000) global ransomware infections in 2016. "On China's most prestigious college campuses, students reported being locked out of their final papers".

The good news is, these attacks are preventable if you keep your software up to date and your guard up. The most affected are America shipping companies and healthcare systems in the United Kingdom.

Malware-tracking maps show WannaCry has remained active in Europe over the past 24 hours.

The term ransomware refers to malicious software that infects or locks a computer, preventing access to files.

He said the attack did not have any specific targets. It's a true and damning argument on Smith's part: Whether due to internal leakers or external attackers, two of the most advanced and secretive spy agencies in the world have seen some of their most prized offensive tools snatched out of the shadows and not only made public, but weaponized against British hospitals, Chinese universities, and FedEx.

In India, smaller organisations and individuals are highly vulnerable to worms and ransomware attacks due to their use of pirated software.

The so-called WannaCry hack takes advantage of a vulnerability in Microsoft Windows, leveraging an exploit stolen from the NSA in April to lock the computer systems of companies ranging from hospitals to vehicle manufacturers in exchange for ransom. "An equivalent scenario with conventional weapons would be the US military having some of its Tomahawk missiles stolen", Smith wrote. Microsoft surely wants to continue to sell successive versions of Windows every several years and gradually forget about its earlier attempts-it's the business they're in. With that, Microsoft releases a patch for the vulnerability in March. Rather, it's a Windows vulnerability that the NSA knew about, and which was disclosed in January 2017.

"This was not a tool developed by the NSA to hold ransom data", homeland security adviser Bossert said at Monday's White House briefing.

Prahlad says that updating computers with the latest OS is not a silver bullet against malware, as ransomware variants that take advantage of zero-day vulnerabilities are always possible. Activating the domain worked as a kill switch for the malware.

The news came as health minister Jeremy Hunt confirmed that there had been no dreaded "second wave" of attacks following the initial assault last Friday.

"Unquestionably, it was criminals who unleashed this malware to make money".
