Russian Ransomware Gangs Weaponize Open-Source AdaptixC2 for Advanced Attacks

Russian Ransomware Gangs Weaponize Open-Source AdaptixC2 for Advanced Attacks

Oct 30, 2025 Malware / Cybercrime
The open-source command-and-control (C2) framework known as AdaptixC2 is being used by a growing number of threat actors, some of whom are related to Russian ransomware gangs. AdaptixC2 is an emerging extensible post-exploitation and adversarial emulation framework designed for penetration testing. While the server component is written in Golang, the GUI Client is written in C++ QT for cross-platform compatibility. It comes with a wide range of features, including fully encrypted communications, command execution, credential and screenshot managers, and a remote terminal, among others. An early iteration was publicly released by a GitHub user named " RalfHacker " ( @HackerRalf on X) in August 2024, who describes themselves as a penetration tester, red team operator, and "MalDev" (short for malware developer). In recent months, AdaptixC2 has been adopted by various hacking groups, including threat actors tied to the Fog and Akira ransomware operations, as ...

ThreatsDay Bulletin: DNS Poisoning Flaw, Supply-Chain Heist, Rust Malware Trick and New RATs Rising

Oct 30, 2025 Cybersecurity / Hacking News
The comfort zone in cybersecurity is gone. Attackers are scaling down, focusing tighter, and squeezing more value from fewer, high-impact targets. At the same time, defenders face growing blind spots — from spoofed messages to large-scale social engineering. This week's findings show how that shrinking margin of safety is redrawing the threat landscape. Here's what's making headlines. Hijack Loader expands its reach in Latin America LATAM Targeted by PureHVNC Phishing emails containing SVG file attachments targeting Colombian, Spanish-speaking individuals with themes relating to the Attorney General's office of Colombia have been used to deliver PureHVNC RAT . "The emails entice the user to download an 'official document' from the judicial information system, which starts the infection chain of executing a Hijack Loader executable that leads to the PureHVNC Remote Access Trojan (RAT)," IBM X-Force said .

Russian Hackers Target Ukrainian Organizations Using Stealthy Living-Off-the-Land Tactics

Oct 29, 2025 Vulnerability / Cyber Espionage
Organizations in Ukraine have been targeted by threat actors of Russian origin with an aim to siphon sensitive data and maintain persistent access to compromised networks. The activity, according to a new report from the Symantec and Carbon Black Threat Hunter Team, targeted a large business services organization for two months and a local government entity in the country for a week. The attacks mainly leveraged living-off-the-land (LotL) tactics and dual-use tools, coupled with minimal malware, to reduce digital footprints and stay undetected for extended periods of time. "The attackers gained access to the business services organization by deploying web shells on public-facing servers, most likely by exploiting one or more unpatched vulnerabilities," the Broadcom-owned cybersecurity teams said in a report shared with The Hacker News. One of the web shells used in the attack was Localolive, which was previously flagged by Microsoft as put to use by a sub-group of the ...

10 npm Packages Caught Stealing Developer Credentials on Windows, macOS, and Linux

Oct 29, 2025 Malware / Threat Intelligence
Cybersecurity researchers have discovered a set of 10 malicious npm packages that are designed to deliver an information stealer targeting Windows, Linux, and macOS systems. "The malware uses four layers of obfuscation to hide its payload, displays a fake CAPTCHA to appear legitimate, fingerprints victims by IP address, and downloads a 24MB PyInstaller-packaged information stealer that harvests credentials from system keyrings, browsers, and authentication services across Windows, Linux, and macOS," Socket security researcher Kush Pandya said . The npm packages were uploaded to the registry on July 4, 2025, and accumulated over 9,900 downloads collectively - deezcord.js dezcord.js dizcordjs etherdjs ethesjs ethetsjs nodemonjs react-router-dom.js typescriptjs zustand.js The multi-stage credential theft operation manifested in the form of various typosquatted packages impersonating popular npm libraries such as TypeScript, discord.js, ethers.js, nodemon, react...

New Android Trojan 'Herodotus' Outsmarts Anti-Fraud Systems by Typing Like a Human

New Android Trojan 'Herodotus' Outsmarts Anti-Fraud Systems by Typing Like a Human

Oct 28, 2025 Malware / Mobile Security
Cybersecurity researchers have disclosed details of a new Android banking trojan called Herodotus that has been observed in active campaigns targeting Italy and Brazil to conduct device takeover ( DTO ) attacks. "Herodotus is designed to perform device takeover while making first attempts to mimic human behaviour and bypass behaviour biometrics detection," ThreatFabric said in a report shared with The Hacker News. The Dutch security company said the Trojan was first advertised in underground forums on September 7, 2025, as part of the malware-as-a-service (MaaS) model, touting its ability to run on devices running Android version 9 to 16. It's assessed that while the malware is not a direct evolution of another banking malware known as Brokewell , it certainly appears to have taken certain parts of it to put together the new strain. This includes similarities in the obfuscation technique used, as well as direct mentions of Brokewell in Herodotus (e.g., "BRKWL_...

Researchers Expose GhostCall and GhostHire: BlueNoroff's New Malware Chains

Oct 28, 2025 Malware / Data Breach
Threat actors tied to North Korea have been observed targeting the Web3 and blockchain sectors as part of twin campaigns tracked as GhostCall and GhostHire . According to Kaspersky, the campaigns are part of a broader operation called SnatchCrypto that has been underway since at least 2017. The activity is attributed to a Lazarus Group sub-cluster called BlueNoroff , which is also known as APT38, CageyChameleon, CryptoCore, Genie Spider, Nickel Gladstone, Sapphire Sleet (formerly Copernicium), and Stardust Chollima. Victims of the GhostCall campaign span several infected macOS hosts located in Japan, Italy, France, Singapore, Turkey, Spain, Sweden, India, and Hong Kong, whereas Japan and Australia have been identified as the major hunting grounds for the GhostHire campaign. "GhostCall heavily targets the macOS devices of executives at tech companies and in the venture capital sector by directly approaching targets via platforms like Telegram, and inviting potential victims t...
Why Early Threat Detection Is a Must for Long-Term Business Growth

Why Early Threat Detection Is a Must for Long-Term Business Growth

Oct 28, 2025 Threat Intelligence / SOC Operations
In cybersecurity, speed isn't just a win — it's a multiplier. The faster you learn about emerging threats, the faster you adapt your defenses, the less damage you suffer, and the more confidently your business keeps scaling. Early threat detection isn't about preventing a breach someday: it's about protecting the revenue you're supposed to earn every day. Companies that treat cybersecurity as a reactive cost center usually find themselves patching holes, paying ransoms, and dealing with downtime. Companies that invest in proactive visibility, threat intelligence, and early detection mechanisms stay in the game longer. With trust, uptime, and innovation intact. Let's break down why this strategy directly connects to long-term business success: 1. Early detection drastically lowers the cost of incidents A breach caught at initial access might cost just internal response hours. Caught at data exfiltration — multiply the cost by 10, and a breach caught after regulatory violations kick...

SideWinder Adopts New ClickOnce-Based Attack Chain Targeting South Asian Diplomats

Oct 28, 2025 Cyber Espionage / Malware
A European embassy located in the Indian capital of New Delhi, as well as multiple organizations in Sri Lanka, Pakistan, and Bangladesh, have emerged as the target of a new campaign orchestrated by a threat actor known as SideWinder in September 2025. The activity "reveals a notable evolution in SideWinder's TTPs, particularly the adoption of a novel PDF and ClickOnce -based infection chain, in addition to their previously documented Microsoft Word exploit vectors," Trellix researchers Ernesto Fernández Provecho and Pham Duy Phuc said in a report published last week. The attacks, which involved sending spear-phishing emails in four waves from March through September 2025, are designed to drop malware families such as ModuleInstaller and StealerBot to gather sensitive information from compromised hosts. While ModuleInstaller serves as a downloader for next-stage payloads, including StealerBot, the latter is a .NET implant that can launch a reverse shell, deliver addi...
New ChatGPT Atlas Browser Exploit Lets Attackers Plant Persistent Hidden Commands

New ChatGPT Atlas Browser Exploit Lets Attackers Plant Persistent Hidden Commands

Oct 27, 2025 Artificial Intelligence / Vulnerability
Cybersecurity researchers have discovered a new vulnerability in OpenAI's ChatGPT Atlas web browser that could allow malicious actors to inject nefarious instructions into the artificial intelligence (AI)-powered assistant's memory and run arbitrary code. "This exploit can allow attackers to infect systems with malicious code, grant themselves access privileges, or deploy malware," LayerX Security Co-Founder and CEO, Or Eshed, said in a report shared with The Hacker News. The attack, at its core, leverages a cross-site request forgery ( CSRF ) flaw that could be exploited to inject malicious instructions into ChatGPT's persistent memory. The corrupted memory can then persist across devices and sessions, permitting an attacker to conduct various actions, including seizing control of a user's account, browser, or connected systems, when a logged-in user attempts to use ChatGPT for legitimate purposes. Memory, first introduced by OpenAI in February 2024, is...
