Filter Out the Noise
Since I started this curated newsletter in June 2017, I’ve clipped ~14,000 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.

4. Google Play has been spreading advanced Android malware for years (Ars Technica, Apr 29 2020)
Attackers behind the campaign used several effective techniques to repeatedly bypass the vetting process Google uses in an attempt to keep malicious apps out of Play. One method was to initially submit a benign version of an app and add the backdoor only after the app was accepted.

The Domain Name System, or DNS, is one of the most foundational services of the Internet, turning human-friendly domain names into IP addresses. Often handled by specialized network engineers within an organization, DNS can feel like a black box to people who don’t deal with it often.
