We analyzed 400 DDoS-Stresstests from 2022 and gathered very interesting insights into the current state of protection/mitigation-solutions, what works (well), what doesnt, and especially: WHY.

For 19 years, GPS satellites have secretly broadcast a “numbers station” in their public signals. We decoded 12M messages: a 2011 flash where 31 of 32 satellites flipped in hours, “ghost” substrings repeating years apart, and a “TEXT” prefix spreading now. https://t.co/xz3svmqiDa

The OG of cyber investigations, @briankrebs, just published a follow-up to our investigation into the Stark Industries hosting network. His piece adds new detail, including MIRhosting’s first official response.
In his May 2024 deep-dive, Krebs first put Stark Industries on the map. We built on his work, and two years later, with last week’s arrests by Dutch authorities, the Stark saga is moving into new territory: what happens to the many companies across Europe that hosted the thinly disguised, rebranded Stark?
Our original investigation (in English):

Dutch authorities have arrested two men and seized over 800 servers in a major crackdown on infrastructure used to support Russian-linked cyberattacks, influence operations, and disinformation in Europe. The operation targeted the persons behind MIRhosting and WorkTitans BV / the[.]hosting, who took over hosting assets from the EU-sanctioned Stark Industries Solutions network after earlier sanctions on its previous operators (PQHosting / Neculiti brothers). Read the full story behind the takedown in this article by @moltke :

In our "A Silent Shift: The Return of Server-Based Botnets" - report we examine the resurgence of server-based attacker botnets, explain what they are, and discuss why they can pose a threat to established defense mechanisms.
