Lauren Fievisohn, Ph.D, Senior Threat Researcher from Silent Push, is sharing their work on "Meet DriveSurge: A New Threat Actor Using ClickFix and Fake Update Drive-By Attacks in Thousands of Compromised Sites." Silent Push researchers have identified a newly named threat actor, DriveSurge, which has compromised thousands of legitimate websites and uses ClickFix and fake browser update lures to distribute malware at scale through a pay-per-install operation. The group leverages a traffic distribution system called zTDS to silently redirect visitors from trusted websites to malicious payloads, while employing sophisticated infrastructure, obfuscation, and fingerprinting techniques to evade detection. The report also details how DriveSurge targets both Windows and macOS users and provides defenders with eight infrastructure fingerprints to help identify and disrupt the campaign.
Today we are joined by Geoff White, host of Cyber Hack and BBC journalist, taking a deep dive into the Conti ransomware gang. Geoff explores an in-depth investigation into the notorious Conti ransomware gang, drawing from thousands of leaked internal messages to reveal how the group operated behind the scenes. The research uncovers surprising internal debates over targeting healthcare organizations, the fallout from accidentally exposing sensitive Saudi royal family data, and frantic efforts to free an arrested gang member. It also offers a rare look at Conti leader Vitaliy Kovalev through newly uncovered video footage, providing an unprecedented glimpse into one of cybercrime's most influential figures.
This week we are joined by Daniel Schwalbe, Chief Information Security Officer & Head of Investigations at DomainTools, discussing their work on "ZionSiphon OT Malware First Attempts? Psyops? Both?" Researchers at DomainTools take a closer look at ZionSiphon, a purported operational technology malware sample targeting the water sector, and find that despite its alarming appearance, it lacks many of the capabilities needed to function as a credible cyber-physical weapon. They break down the malware's architecture, its operational shortcomings, and why it may be more of a prototype or proof of concept than a deployable threat. With heightened concern surrounding attacks on critical infrastructure amid the ongoing U.S.-Iran conflict, the research offers timely insight into separating genuine OT threats from overhyped malware.
TranscriptThis week, we are joined by Tom Kellermann, TrendAI's VP of AI Security and Threat Research, discussing their work on "Inside SHADOW-WATER-063’s Banana RAT: From Build Server to Banking Fraud." Researchers from TrendAI's MDR team uncovered the full operation behind Banana RAT, a sophisticated banking trojan they track as SHADOW-WATER-063, by analyzing both attacker infrastructure and infected victim systems. The malware uses fileless PowerShell execution, layered obfuscation, and remote-control capabilities to steal credentials, manipulate banking sessions, intercept Pix QR code payments, and facilitate financial fraud targeting Brazilian banks. The campaign appears to be operated by a Brazilian Portuguese-speaking cybercriminal group with ties to the broader Tetrade banking malware ecosystem and may be evolving toward a malware-as-a-service model.
TranscriptMartin Zugec, Technical Solutions Director at Bitdefender, discussing their work on "FamousSparrow APT Targets Azerbaijani Oil and Gas Industry." Bitdefender researchers uncovered a sustained cyber espionage campaign by the China-linked FamousSparrow group targeting an Azerbaijani oil and gas company, highlighting the growing focus on critical energy infrastructure in the South Caucasus. The attackers repeatedly exploited the same vulnerable Microsoft Exchange server over multiple months, deploying evolving versions of Deed RAT and Terndoor malware through sophisticated DLL sideloading techniques designed to evade detection and maintain persistence. The operation underscores FamousSparrow's adaptability and persistence, demonstrating how advanced threat actors continually refine their tooling and return to compromised environments until vulnerabilities are fully remediated and access is cut off.
