>> A ransomware attack hitting computers across the world Tuesday taking out servers at Russia's biggest oil company, disrupting operations at Ukrainian banks and shutting down computers at multi-national shipping and advertising firms. Reuters cyber-security correspondent, Dustin Volz.>> It appears that Russia and Ukraine were hit most heavily and this is very similar to the WannaCry attack that we saw in May.
That one affected hundreds of thousands of computers in 150 countries. This one so far is much smaller in scale, but it's still yet another ransomware attack that's downing banks critical infrastructure in some places. Chernobyl in Russia, the nuclear power facility has been affected.>> The ransomware virus crippled computers running Microsoft Windows by encrypting hard drives and overwriting files.
Then demanded $300 in BitCoin payments to restore access. US Department of Homeland Security advising victims not to pay the extortion, saying that doing so does not guarantee that access will be restored. Tuesday's attack was less damaging than WannaCry since many people have since patched up there vulnerability in Microsoft.
>> But fundamentally we're still seeing a lot of companies, a lot of individual computer users in all sorts of places not using or not patching their systems. And that leaves them open to attack and this continues to be a problem not just for them and their work, but more broadly we see hospitals getting affected, banks and so forth so this is a serious problem.
>> The attacks have once again, fanned criticism of the NSA which had surveillance tools leaked online that were re-purposed by hackers to carry out both Tuesday's attack, and the WannaCry campaign last month. After hitting Russia and Ukraine, the virus infected other victims across Britain, France, Germany, Italy, Poland, and the United States, among others.
