North Korea link emerges in global cyber attacks

While some Korean companies and individuals have been reportedly affected the government has said its computers have not.

The North's KCNA news agency said Sunday's test launch verified the homing feature of the warhead that allowed it to survive "under the worst re-entry situation" and accurately detonate. New sanctions were expected to be discussed at a closed council meeting Tuesday, the diplomats said, speaking on condition of anonymity because talks have been private.



What is the 'ransomware' WannaCry worm and how does it spread?

The attack grew over the weekend after emerging on Friday afternoon (12 May) from 45,000 victim systems to an estimated 200,000, crippling large organisations from the NHS in the United Kingdom to Renault factories in France, Telefónica in Spain as well as Russia's second largest mobile operator, MegaFon.



Gov't issues warnings against WannaCry ransomware ransomware

Ransomware is not a sophisticated type of attack, but WannaCry is more complex and coordinated than most. The attack is unique, according to Europol, because it combines ransomware with a worm function, meaning once one machine is infected, the entire internal network is scanned and other vulnerable machines are infected.
