'WannaCry' cyber attack: How to protect your computer

"Until hundreds of thousands of unpatched Windows systems have been updated, a WannaCry 2.0 campaign could effectively pick up where Friday's attack left off", he wrote. It encrypts all the data it can find then demands a ransom for the encryption key.

Those who use Apple's Mac computers are not at risk of the recent ransomware attack.

Marcus Hutchins, a 22-year-old employee of MalwareTech, has managed to halt the spread of the malware after registering a domain name to track the virus' spread.

A worldwide WannaCry (also known as WannaCrypt) ransomware attack that wreaked havoc in United Kingdom hospitals and Russian telecom networks, could resurface today as workers return to the office, experts have warned.

Higher US crude output should pressure oil prices
Russian Federation and 10 other non-OPEC producers agreed to cut half as much. Aramco had previously maintained supplies to important Asian customers.

As the first wave of WannaCry attacks struck computers across the world, Microsoft not only advised Windows users to patch their systems, but also upgrade their anti-virus software which acts as the first line of defence in detecting malware. Other countries and companies affected in a major way include FedEx, Russia's interior ministry, Japanese companies Hitachi and Nissan and Renault, the French automobile manufacture. Unfortunately, the only source for identifying the attack seems to be a single source - so, in other words, beware what you hear about it. Making the payment, they say, just proves the malware to be effective. Most companies needing to restore their operations right away would have turned to back-ups, if available, by now.

"It's very important everyone understands that all they (the hackers) need to do is change some code and start again".

Homeland security says that despite the range of the hack, only about $70 000 worth of bitcoin was paid to hackers. Microsoft also recommends running its free anti-virus software for Windows.

Even before the WannaCrypt disaster, Smith said he and his colleagues had already seen vulnerabilities stored by the Central Intelligence Agency show up on WikiLeaks. So when the vulnerabilities fall into the wrong hands, its akin to the "U.S. military having some of its Tomahawk missiles stolen", without offering the proper defense to protect consumers against the government's own weapons. For instance, require strong passwords that must be changed periodically and constantly remind employees to assist the IT department to apply software patches on all employee workstations by shutting down nightly.
