∗∗∗ Microsoft rolls out passkey auth for personal Microsoft accounts ∗∗∗
---------------------------------------------
Microsoft announced that Windows users can now log into their Microsoft consumer accounts using a passkey, allowing users to authenticate using password-less methods such as Windows Hello, FIDO2 security keys, biometric data (facial scans or fingerprints), or device PINs. [..] Microsoft had already added passkey support to Windows for logging into websites and applications, but with the additional support for Microsoft accounts, consumers can now easily log in without entering a password.

∗∗∗ Scans Probing for LB-Link and Vinga WR-AC1200 routers CVE-2023-24796, (Thu, May 2nd) ∗∗∗
---------------------------------------------
Before diving into the vulnerability, a bit about the affected devices. LB-Link, the make of the devices affected by this vulnerability, produces various wireless equipment that is sometimes sold under different brands and labels. This will make it difficult to identify affected devices. These devices are often low-cost "no name" solutions or, in some cases, may even be embedded, which makes it even more difficult to find firmware updates. [..] And yes, the vulnerability evolves around the "user=admin" cookie and a command injection in the password parameter. This is too stupid to waste any more time on, but it is common enough to just give up and call it a day.

∗∗∗ Mal.Metrica Redirects Users to Scam Sites ∗∗∗
---------------------------------------------
One of our analysts recently identified a new Mal.Metrica redirect scam on compromised websites, but one that requires a little bit of effort on the part of the victim. It’s another lesson for web users to be careful what they click on, and to be wary of anything suspicious that pops up in their browser — even if it’s coming from a website that they would otherwise trust.

∗∗∗ Europol op shutters 12 scam call centers and cuffs 21 suspected fraudsters ∗∗∗
---------------------------------------------
A Europol-led operation dubbed “Pandora” has shut down a dozen phone scam centers, and arrested 21 suspects. [..] Beginning in December 2023, German investigators deployed more than 100 officers to trace the scam calls back to the source - call centers run by crooks - and then monitored them. That effort resulted in the interception of more than 1.3 million "nefarious conversations." Baden-Württemberg State Criminal Police officers had to set up a call center of their own so that they could contact potential victims, warning more than 80 percent of them.
