Filter Out the Noise
Since I started this curated security news in June 2017, I’ve clipped ~19,000 articles and narrowed them down into the best 20 per day & best 15 per week. This is my favorite way to cut through all the security marketing and hype. If you’re enjoying it, tell a friend. If you hate it, tell an enemy.

5. Recycle Your Phone, Sure, But Maybe Not Your Number (Krebs on Security, May 19 2021)
Many online services allow users to reset their passwords by clicking a link sent via SMS, and this unfortunately widespread practice has turned mobile phone numbers into de facto identity documents.

This article talks about label standard and best practices for Kubernetes security, a common area where I see organizations struggle to define the set of labels required to meet their security requirements. My advice is to always start with a hierarchical security design that can achieve your enterprise security and compliance requirements, then define your label standard in alignment with your design.

9. The state of AppSec and the journey to DevSecOps (Help Net Security, May 23 2021)
While the perceived benefits of DevSecOps to both security and DevOps are high, much progress must be made in defining a repeatable and consistent governance model for true DevSecOps to take hold, a ZeroNorth survey of 250 global security, DevOps and IT professionals reveals.

15. Double-Encrypting Ransomware (Schneier on Security, May 21 2021)
This seems to be a new tactic:

Emsisoft has identified two distinct tactics. In the first, hackers encrypt data with ransomware A and then re-encrypt that data with ransomware B. The other path involves what Emsisoft calls a “side-by-side encryption” attack, in which attacks encrypt some of an organization’s systems with ransomware A and others with ransomware B. In that case, data is only encrypted once, but a victim would need both decryption keys to unlock everything.
