Cyberespionage campaigns are becoming increasingly complex due to the close collaboration between distinct APT groups. Learn how China-aligned Earth Estries provides initial access to compromised assets for Earth Naga (Flax Typhoon) to continue exploitation: www.trendmicro.com/en_us/resear....

One of the botnets that is using a modular approach that will likely be able to circumvent network-based access controls against residential proxies is known as BadBox 2.0. The FBI issued an advisory yesterday: www.ic3.gov/PSA/2025/PSA...

This modular model is already employed by residential proxy providers in the Far East who obtain millions of residential proxies by exploiting vulnerabilities in the supply chain of inexpensive IoT devices and by shipping pre-infected Android Open Source Project-supported devices (AOSP).

We anticipate that residential proxy providers will seek to bypass connection and session-based access controls, by uploading separate software modules to residential endpoints. These modules can independently carry out specific tasks like advertisement fraud without relying on proxied connections.

Residential proxies are a key enabler of cybercrime today. This creates a growing need for connection and session-based access control. We used Ja4T fingerprinting that successfully tagged incoming connections from residential proxies to 1,500 IDS systems. www.trendmicro.com/vinfo/us/sec...

One of my favorite pieces of evidence we were able to obtain was 7 videos with English text, which painstakingly explain how to set up a Beavertail C&C. The screen recording, lasting more than 1 hour, was created by someone logged in with a BlockNovas account from an IP address probably in Russia.

DPRK cybercrime uses Russian infrastructure in Khasan and Khabarovsk, masked by VPNs, proxies, and RDPs. One fictitious DPRK company to lure IT professionals with interviews was BlockNovas. FBI seized BlockNovas' site and a related C&C on April 23, 2025. Read more: www.trendmicro.com/en_us/resear...

Roman Dobrokhotov and Christo Grozev have extensively reported on FSB and GRU. Read this to learn about their ordeal when a team, led by Marsalek, was hunting them down. The story has fun elements and close calls. It highlights the dangers journalists face as they inform us: theins.ru/en/inv/279034

Earth Koshchei (APT29): A cyberespionage group targeting critical sectors with stealthy techniques. Here’s what you need to know: www.trendmicro.com/en_us/resear... #Cybersecurity #ThreatIntel with @feikeh.bsky.social

Since Aug 2024 Earth Koshchei (APT29, Midnight Blizzard) used 193 RDP relays and 34 rogue backends against military, MFAs and others. The campaign peak was likely preceded by barely audible campaigns that ended with a bang in Oct 2024. Details and indicators here: www.trendmicro.com/en_us/resear...

Nsocks provides an alternative explanation: "Competitors have hired an organization that has blocked our back-connect servers and continues DDOS attacks." Nsocks now also mandates authentication for their SOCKS5 entrance nodes (which was not the case previously - security by obscurity)

One week ago Lumen/Shadowserver sinkholed Water Barghest C&Cs. Nsocks (alleged seller of Ngioweb bots) apparently suffers from this: US proxies down to 4494 (was 14037), EU proxies down to 2038 (was 9092). I expected a faster recovery. Still expect Water Barghest will make their botnet more robust.

Water Barghest automated each step between finding vulnerable IoT devices to offering them for rent on a commercial residential proxy provider. Water Barghest's infrastructure was used to exploit Cisco IOS XE devices with a 0-day in October 2023. Read more here: www.trendmicro.com/en_us/resear...
