AusCERT Week in Review for 21st February 2020

Greetings,

On Monday 2 March the AusCERT External Security Bulletins (ESB) and AusCERT Security Bulletins (ASB) are going to be sent from bulletins@auscert.org.au.

You will still receive the bulletin service as usual but the source email address will be changed to bulletins@auscert.org.au.

This change is being executed to allow for easier filtering of one of our largest volumes of email correspondence.

However, if you are currently automating the bulletins you receive from auscert@auscert.org.au, make sure you tweak your scripts / update your mail rules to match on Monday 2 March.

Please see below for a selection of this week's interesting news articles and security advisories.

Why fixing security vulnerabilities in medical devices, IoT is so hard

When your family opened up that brand-new computer when you were a kid, you didn’t think of all of the third-party work that made typing in that first BASIC program possible. There once was a time when we didn't have to worry about which companies produced all the bits of licensed software or hardware that underpinned our computing experience. But recent malware attacks and other security events have shown just how much we need to care about the supply chain behind the technology we use every day.
The URGENT/11 vulnerability, the subject of a Cybersecurity and Infrastructure Security Agency advisory issued last July, is one of those events. It forces us to care because it affects multiple medical devices. And it serves as a demonstration of how the software component supply chain and availability of support can affect the ability of organizations to update devices to fix security bugs—especially in the embedded computing space.
