The cybersecurity company Crowdstrike's share is soaring with 14 percent in futures trading on Wall Street after a wave of IT problems that have knocked out air and rail traffic, banks, and many other users of Microsoft 365 software.
Nasdaq-listed Crowdstrike is being pointed out as responsible for the major problems created.
Software giant Microsoft is also falling in futures trading, down 2.8 percent.
Insurance companies with exposure to cybersecurity are also taking a hit as a wave of compensation claims is expected due to the problems.
The two companies state that they have identified the problem – which began after Crowdstrike made an update to its security system – but the effects are prolonged for many users.
