Navalny was poisoned with exotic frog toxin, five Western nations confirm

Multiple labs have independently analyzed biological samples taken from Alexei Navalny’s body and found epibatidine, a highly toxic alkaloid sourced from a South American poisonous frog.

TrendAI formalizes threat attribution as a structured, repeatable discipline by combining standardized evidence scoring, relationship mapping, and bias testing, with a temporary stage that separates clustering from final naming. Article on how we attribute: www.trendmicro.com/vinfo/us/sec...

#BREAKING #ESETresearch identified the wiper #DynoWiper used in an attempted disruptive cyberattack against the Polish energy sector on Dec 29, 2025. At this point, no successful disruption is known, but the malware’s design clearly indicates destructive intent. 1/5

Trend Micro tracks SHADOW-VOID-042 spear-phishing (Nov 2025) using Trend Micro-themed lures and a decoy site mimicking Trend’s corporate style, targeting defence, energy, chemicals, cybersecurity and ICT sectors. www.trendmicro.com/en_us/resear...

We investigated an #APT with links to Void Rabisu (Romcom) that used Trend Micro updates as a lure in a recent campaign involving vulnerability exploitation. There were at least 4 stages before the final payload, some of them being tailored to the targeted machine www.trendmicro.com/en_us/resear...

Recently various industries, including Trend Micro, were targeted by a Trend Micro-themed campaign. Trend Vision One™ stopped it early in the kill chain. The campaign somewhat aligns with Void Rabisu (ROMCOM). For now we track this temporarily under SHADOW-VOID-042 www.trendmicro.com/en_us/resear...

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....

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...

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.

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...

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...
