So what do we know so far?
1. The attack started in the UK Friday afternoon affecting most recognisably the NHS
2. Since gone global - literally
3. The Telecoms Spanish giant Telefonica has been impaired which is a deeply worrying sign.
4. The malware was stolen from the National Security Agency by a group calling itself the Shadow Brokers. Hard to make this up.
5. The attackers are expected to pocket $1bn from this. I hate to admit this but crime does sometimes pay - on this occasion, very handsomely.
6. A 22 year old British researcher has temporarily halted it's spread. This is why it has not yet crossed to America.
7. Copycats are now expected. If you can make a cool $1bn from your bedroom, hardly a surprise.
8. The global security system has been caught monumentally unprepared.
9. The malware took advantage of a weakness in the Windows operating systems. Patches had been released a few months earlier but these did not cover earlier OS's.
10. Ransom attacks have been on the rise over the last 18 months and are expected to rise.
24 hours after it first emerged, it has been called the first global, coordinated ransomware attack using hacking tools developed by the NSA, crippling over a dozen hospitals across the UK, mass transit around Europe, car factories in France and the UK, universities in China, corporations in the US, banks in Russia and countless other mission-critical businesses and infrastructure.
