13. What is Crowdstrike?published at 19:4819:48Liv McMahon
    Technology reporterCrowdstrike is a cybersecurity company founded in 2011 with the aim of safeguarding the world’s biggest companies and hardware from cyber threats and vulnerabilities.It specialises in endpoint security protection and tries to prevent malicious software or files from hitting corporate networks from devices that connect to them, such as phones and laptops.It also aims to protect the data of companies which have shifted from guarding it under their own roof, or on their own servers, to so-called cloud providers.The Texas-based firm was co-founded by entrepreneurs George Kurtz, who remains chief executive, and Dmitri Alperovitch. It listed its shares publicly on the tech heavy Nasdaq stock exchange in 2019.Since it first launched, the company has seemingly played a key role in helping firms investigate cyber-attacks.In 2016 Crowdstrike was called in by the US Democratic National Committee, the strategy arm of the Democrat Party, to investigate a breach into its computer network.IMAGE SOURCE, GETTY IMAGESImage caption, Crowdstrike chief executive George KurtzShare

16. Big firms back online while disruption continues for smaller businessespublished at 19:1019:10Joe Tidy
    Cyber correspondentThere’s an interesting and strange lesson amidst the chaos.The biggest firms with the largest number of affected computers seem to be popping back up online the fastest. This is what you’d expect, of course, but it possibly points to these larger richer companies having better resourcing of IT staff and better resilience measures in place. The fix for this is largely a manual one and that means having IT staff at affected computers.It’s the small and medium sized businesses that I think are struggling the most. They have fewer computers to fix but also fewer staff to go out and do the fixing. For the big firms that make the headlines, this is largely proving to be short and sharp. But, of course, we also don’t know what happens next with the backlogs of work, appointments, missed deadlines and general damage to organisations. The most acute example of this is in airlines which are seemingly back online and running nearly normally, but with monstrous backlogs to work through. Share
