22 million WannaCry ransomware attack attempts blocked by Symantec

22 million WannaCry ransomware attack attempts blocked by Symantec”

The software is WannaCry ransomware which took over the machines of more than 150 countries including India.

You've heard the phrase "the road to Hell is paved with good intentions", right?

The new hacking tool also exploits weaknesses in older versions of Microsoft Windows software and was stolen from the US National Security Agency, like the stolen tool that formed the basis of last week's WannaCry attack. More than 300,000 machines in 150 countries have been hit so far, USA homeland security advisor Tom Bossert said in a press briefing on Monday. The attack since has been believed to be halted, by an anonymous specialist known only as MalwareTech. Typically the price increases over time until the end of a countdown, when the files are destroyed. If your computer is infected by WannaCry, experts agree the best solution is to wipe it clean and restore it from a recent backup.

The Ransomware WannaCry virus, that caused havoc globally, has also wormed its way into India.

Security firms have suggested that users immediately disconnect the infected device from the local network to contain the spread of infection.

How many XP-powered PCs does that translate to? Opposed to the regular ransomware that encrypts just the local machine it lands on, this type spreads throughout the organization's network from within, without having users open an email or malicious attachment. But, Conficker does no immediate damage and hides so that it can use infected computers as part of a "botnet" to send out spam and fake antivirus software.

You're out of luck. But they appear to be less damaging than WannaCry. But Darien Huss, a ProofPoint researcher in IN, confirmed that what MalwareTech had actually triggered was a "kill switch" that instructed WannaCry to stop spreading.

For a variety of reasons, that fix never made it onto the affected computers. Even after payment, the ransomware doesn't automatically release your computer and decrypt your files, according to security researchers.

Great, so I have to pay these monsters to get my computer back?

The hackers behind WannaCry only accept ransom paid via BitCoin, a digital currency that ensures that the transaction can not be traced. It's a process that's entirely manual and contains a serious flaw: The hackers have no way to prove who paid off the ransom. And after a few days, the files are permanently locked. It's a little counterintuitive, but experts say it's much more secure than the alternative, which is reusing the same password across multiple websites.

Does WannaCry affect my Mac, iPhone or Android?

Even though it no longer supports XP, Microsoft took the unusual step of issuing an emergency patch for Windows XP, Windows 8, and Windows Server 2003 on Friday night.

At first blush, the news would seem like a major problem for Microsoft - more evidence of vulnerabilities in Windows.

Instead, organisations such as the NSA should disclose computer vulnerabilities to their manufacturers, Microsoft argues.

When it hits businesses and hospitals, there is extra pressure to get rid of the ransomware quickly.

India's cyber security agency today asked individuals and organisations to shield themselves from a digital worm that has threatened computer users worldwide with data loss, prompting the RBI to relay the message to banks.

Wall Street Journalist Katy Barnato on Twitter shared a graphic that explains how the ransomware works. When his website started getting hits from the malicious software, MalwareTech told ABC News he anxious he'd triggered the program to do something very bad.
