WannaCry Ransomware: Microsoft Calls Out NSA For 'Stockpiling' Vulnerabilities

WannaCry Ransomware: Microsoft Calls Out NSA For 'Stockpiling' Vulnerabilities

And WannaCry threatens to create even more havoc on Monday when people return to work.

Tehan declined to provide details on the three affected companies, but said the first Australian company reported as hit was not "a government organisation or a hospital or anything like that". And it's expected to cause more problems on Monday.

The warning echoed that from Europe's policing agency earlier Sunday.

The ransomware, which has spread globally, has been infecting computers by exploiting a Windows vulnerability involving the Server Message Block protocol, a file-sharing feature. When you click on anything, a pop-up window opens where the attacker asks for more ransom to decrypt files.

If you are attacked, the best defense against ransomware is to have secure backups of all critical systems so that if you are attacked, you can restore your systems quickly without having to pay the ransom. Many of these attacks occurred in Europe and Russian Federation.

Shadow Brokers's identity still remains a mystery, albeit security experts think the group could be tied to the Russian government. However, it is extremely ironic that just eight weeks ago, Microsoft released a patch for the "WannaCry" vulnerability. Patched computers carry a much lower risk of being infected by malware or ransomware than those without an update.

Trump delays decision on Paris climate agreement, spokesman says
Espinosa refused to comment on the impact of a possible USA withdrawal from the talks or even the entire climate change accord. That interpretation is contested by many legal experts, however, as well as participants in past global climate negotiations.

Two researchers in their 20's had halted the ransomeware attack on Saturday after discovering and activating the software's "kill switch".

"There are plenty of reasons people wait to patch, and none of them are good", Ziv Mador, a security researcher at Trustwave's Israeli SpiderLabs and a former Microsoft researcher, told Reuters.

"To be clear, Microsoft would prefer that companies upgrade and realise the full benefits of the latest version rather than choose custom support".

"The way these attacks work means that compromises of machines and networks that have already occurred may not yet have been detected, and that existing infections from the malware can spread within networks", Britain's National Cyber Security Center said in a statement on Sunday. The tool is called WCRYSLAP and can be found here. Immediately shut down the network to prevent continued encryption.

The ransomware took advantage of a flaw in Microsoft's Windows operating system.

Urging businesses and computer users to keep their systems current and updated, Smith says the WannaCry attack shows the importance of collective action to fight cyber crime. Turn on auto-updaters where available (Microsoft offers that option). Microsoft released Windows 8 in 2012 and Windows 10 in 2015. Many of those were unpatched, and an easy mark for WannaCry.
