WannaCry: The industry's wake-up call

Ken Allan, security expert at PA Consulting Group shares his insights on the recent WannaCry ransomware which brought global systems to a standstill.

The article notes that Friday May 12 may be seen as a turning point for global IT security – the date when the Wannacry ransomware code infected more than 200,000 computers in 150 countries in the space of a few days. 

It goes on to say that much damage was caused with train service disruption and the cancellations of hospital appointments and operations. 

Commenting on this, Ken says: “Much of the damage came not from IT systems, but because organisations were forced to revert to paper processes. 

“A lot of resilience comes from not having 100% digital infrastructure, but as organisations seek greater efficiency through automation, this will diminish.”

The article goes on to assess how organisations’ can best protect themselves against attack. It concludes that the most important lesson from WannaCry is that organisations’ and individuals need to check and test data recovery plans.
