US-based cybersecurity firm CrowdStrike has warned of hackers reserving domain names to run “CrowdStrike Support” scams after its customers were hit by a widespread malware attack on Thursday. CrowdStrike’s research revealed the attackers were trying to send fraudulent mails and make fake calls pretending to be CrowdStrike staff to trick people into giving up their credentials.
