How to avoid the ransomware attack

Zimbabwe is one of the countries targeted by the massive cyber-attack called WannaCry ransomware which has hit computers in 104 countries including the Russian Federation, the UK, Ukraine and China. While a United Kingdom security researcher managed to stop the spread of the virus, hackers have issued new versions that cybersecurity organizations are trying to counter and stamp out.

Problems with cyber security in the NHS was highlighted previous year by Dame Fiona Caldicott, the national data guardian, who warned issues were given insufficient priority and that health bodies persisted in using obsolete computer systems, The Times reported.

The US security firm Symantec said the attack appeared to be indiscriminate.

The full extent of the damage from the cyberattack felt in 150 countries was unclear and could worsen if more malicious variations of the online extortion scheme appear. "Otherwise they're literally fighting the problems of the present with tools from the past".

In Zimbabwe, many Windows computers stay unpatched. In this May 12, 2017 photo, a display panel with an error can be seen at the main railway station in Chemnitz, Germany.

"Or we could potentially see copycats mimic the delivery or exploit method they used", he said. It said it believed the difficulties are linked to the global cyberattack but they haven't so far harmed its business operations.

The so-called Wanna Cry ransomware attack knocked out major private companies and government infrastructure in Europe on Friday evening.

First, the concept of ransomware: Ransomware uses a typical ransom situation, except this is like a virus* that will block your access to files until you pay the person who unleashed it on your computer.

"The problem is the larger organizations are still running on old, no longer supported operating systems", said Lawrence Abrams, a New York-based blogger who runs BleepingComputer.com.

Smith also called cyberattack protection a "shared responsibility" between companies and customers.

Telefónica: Spanish authorities confirmed the Spanish telecom company Telefónica was one of the targets, though the attack affected only some computers and did not compromise the security of clients' information. True, it can be argued that data collected from accessing enemy computers with a vulnerability could potentially keep U.S. citizens safe too. Security agencies in affected countries were racing to find out.

A number of hospitals in England and Scotland were forced to cancel procedures after dozens of NHS systems were brought down in Friday's attack.

But Prime Minister Theresa May has rejected claims the government ignored warnings the NHS was vulnerable to a possible attack.

British Home Secretary Amber Rudd said Saturday that 45 public health organizations were hit, but she stressed that no patient data had been stolen.
