🚨 Top Headlines

Firing of 130 CISA staff worries cybersecurity industry

Summary: The firing of upwards of 130 cybersecurity professionals at the US Cybersecurity and Infrastructure Security Agency (CISA) is a disaster for the US, but also for many of its allies that count on close collaboration, a security expert said Thursday.

David Shipley, CEO of Beauceron Security, said he “struggles to think of another government agency that has built so much credibility and goodwill and respect across the private sector as what CISA has done. [The dismissals] are wholly undeserved, foolhardy and it’s like you can see the iceberg and you decide to speed the Titanic up. That seems like a bad thing to me.”

New Mac Infostealer Warning—Do Not Visit These Sites

Summary: There’s a very reasonable argument to suggest that Microsoft devices are more at risk than Apple ones, thanks to the number of Windows users and the accompanying effort that cybercriminals put into attempts to compromise them. That doesn’t mean that Windows is an inherently insecure operating system, however, and Windows 10 users are urged to upgrade, for free, to Windows 11 before security support for the former stops being provided.\
