I’m thrilled to share my latest blog post! This one focuses on the bug hunting process: inspiration, approach, and execution. I also provide a retrospective on how the bug was introduced and analyze the insufficient “patch”. Check it out: https://securityintelligence.com/x-force/little-bug-that-could

Announcement is out. Good on Microsoft for finally reaching a sane conclusion.

- Recall won’t ship as a feature at launch on Copilot+ PCs any more.

- Won’t be available in Insider preview channel at launch, as it was pulled.

When it does appear in preview channels, privacy and security researchers need to keep a close eye on what Microsoft are doing with the feature.

Microsoft tried developing this feature in secret in a way which tried to avoid scrutiny. Thank you to everyone who stood up.

VS Code extensions lacking a permission model and sandboxing as well as Microsoft not verifying most supplied information, creates quite a significant supply chain attack vector.

We found a critical vulnerability in #PuTTY SSH client with NIST P-521 keys, that allows private key recovery from only 60 signatures, CVE-2024-31497! If you use #Putty or #Filezilla with ECDSA P-521, upgrade now and generate a new key! Joint work with @Skrillor!

Here's my suggestions for "lessons learned" from the xz attack:

* Upstream code should be pulled from the git, not some random tarball
* All requests to disable valgrind, memory sanitation etc. in tests should be met with extreme scepticism and caution
* We need to call out people bullying open source maintainers
* We need to find ways to support maintainers before they burn out
* We need to establish a culture of succession for open source maintainers

I accidentally found a security issue while benchmarking postgres changes.

If you run debian testing, unstable or some other more "bleeding edge" distribution, I strongly recommend upgrading ASAP.

Ivanti Connect Secure CVE-2024-22024 - Are We Now Part Of Ivanti?

As astute readers of our Twitter account (https://twitter.com/watchtowrcyber) and blog will know, we’ve recently been heavily involved in understanding the recent spatter of vulnerabilities in Ivanti products - most recently, their Connect Secure product which portrays itself as an SSLVPN device. We’re incredibly proud of
