Users should also look for malicious email messages that often masquerade as emails from companies or people you regularly interact with online.
Thanks to a lucky find by a UK-based security researcher, yesterday's massive global ransomware attack is reported to be slowing down today.
Dozens of countries were hit with a huge cyberextortion attack Friday that locked up computers and held users' files for ransom at a multitude of hospitals, companies and government agencies.
The Federal government has confirmed an global cyber attack that hit at least 74 countries has reached Australia, with one local business "likely" to have been affected by malicious ransomware.
"The NHS was not particularly targeted".
"But will simply have been that the ransomware has sought out those organisations that are running susceptible devices", Mr Woodward said.
The perpetrators have yet to be identified and the National Crime Agency (NCA), which is also part of the investigation, has said that there is "no indication that United Kingdom policing or other government departments have been infected with the ransomware".
A worker at the plant told Sky News that work ground to a halt on Friday night as the ransomware countdown clock appeared on computers on the production line.
"Thus we initially unintentionally prevented the spread and and further ransoming of computers infected with this malware", he writes.
In another development, it's being reported that the second version of the ransomware, i.e., WannaCry 2.0, is spreading. Security firm Avast released a report, according to which the company had seen around 75000 cases of Ransomware around the globe by the name of WannaCry and other similar names.
Russia's Interior Ministry says it has come under cyberattack.
Code for exploiting that bug, known as "Eternal Blue", was released on the internet in March by a hacking group known as the Shadow Brokers. Kaspersky Lab said it had recorded incidents in 74 countries, mostly in Russian Federation, but noted that its visibility "may be limited and incomplete". A number of countries and origination have been affected.
Cluley said yesterday's attack also highlighted the risks that organizations take by not investing in updated IT systems and security.
Unfortunately, computers already infected with Wana Decryptor will remain infected, he said.
Microsoft said the situation was "painful" and that it was taking "all possible actions to protect our customers".
