Good morning, everyone!

This week’s critical vulnerabilities:
  • Apple has released fixes for vulnerabilities under active exploit. Update now to iPadOS and iOS 16.6.1, watchOS 9.6.2 and macOS, Ventura 13.5.2 (requires agreement to a new license so it won't update automatically, and you'll need to turn off Bluetooth everywhere again after the update)
  • Schweitzer Engineering Labs (SEL) has released patches for critical flaws in its SEL-5030 acSELeratorQuickSet and SEL-5037 GridConfigurator applications
  • Attackers are exploiting vulnerabilities in the MinIO distributed object storage framework, (patches were released in May)

Patch All the Things!

Windows 7: Achilles Heel

Short version: Any PC running Windows 7 should not be exposed to the Internet. Period. Get rid of it or put it behind a secure network segmentation.

Long version: Attackers accessed UK military data through high-security fencing firm's Windows 7 rig

The risk of running obsolete code and hardware was highlighted after attackers exfiltrated data from a UK supplier of high-security fencing for military bases. The initial entry point? A Windows 7 PC ... used to run software for one of the company's manufacturing machines.

Addendum: Anything that is no longer supported by the manufacturer should be replaced (or at least blocked from Internet access) -- operating systems, firmware, applications, devices, anything. If this truly isn't possible, the security implications should be carefully considered. Without manufacturer support, you cannot get security updates. Exposing an unsupported device or application to the Internet is just asking to be compromised.

Have a great week!
