  1. Cyber attackers 'always one step ahead'

    One of the issues with tackling cyber attackers such as the ransomware one is that attackers' tactics are constantly evolving, Emily Orton - from cyber security firm Darktrace - tells the BBC World Service. 

    "The critical problem is that the attackers are always one step ahead. They're always innovating, they're using new vulnerabilities, they're using new exploits to get the better of our defences, so frankly a patch which is based on what an attacker did yesterday is far too late. 

    "Your defence effectively needs to evolve as quickly as your attacker is evolving. That takes a whole new class of technology. It takes things like machine learning, it takes things like artificial intelligence that are going to effectively learn and evolve and catch up with new attacks."

  3. Cyber-attack a wake-up call - Microsoft

    Microsoft has said the ransomware cyber-attack, which has hit 200,000 computers worldwide, should be a "wake-up call" for countries. 

    The software vulnerabilities hoarded by governments had caused "widespread damage", Microsoft's chief legal officer Brad Smith said in a blog post.

    The latest virus exploits a flaw in a version of Microsoft Windows first identified by US intelligence. 

    "We have seen vulnerabilities stored by the CIA show up on WikiLeaks, and now this vulnerability stolen from the NSA has affected customers around the world," Mr Smith wrote.

    "An equivalent scenario with conventional weapons would be the US military having some of its Tomahawk missiles stolen."

  4. NHS cyber-attack

    The NHS has urged patients to use its services as it discovers the full impact of Friday's global cyber-attack.  

    NHS England said there was a "complex emerging picture", amid concerns over thousands of computers being switched back on after the weekend.  

    James Mucklow, head of digital healthcare at PA Consulting, said the NHS and other organisations should be "cautious" when returning to work today.

    However, given the complexity and size of the NHS, which employs about 1.35 million people, the attack has had a "relatively small impact", he told Wake Up to Money.

  5. Good morning

    Computer risk warningPA

    After the global cyber-attack over the weekend, more ransomware incidents could come to light today as workers return to their desks.

    The National Health Service - one of the worst-affected bodies - has warned there could be more problems when computers are switched on this morning, while Europol says the number of attacks is still rising.

    More than 200,000 computers in 150 countries have been affected, with Microsoft - whose operating systems were targeted in the attack - saying it should be a "wake-up call" for governments and companies.
