Huntress researcher uncovers post-Black Hat & DEF CON phishing campaign using X DMs & malicious documents to deliver AMOS, NetSupport RAT, and other malware.
Scammers are creating fake crypto wallet-checking sites that promise to tell you whether a wallet is linked to suspicious activity. Instead, they try to trick you into giving them access to your crypto. What real AML checking looks like AML stands for anti-money laundering. These are rules that require banks and other regulated businesses to screen customers for ties to crime. It’s designed to prevent cybercriminals from hiding or moving illegally obtained money. In the crypto world, this…
Most wrong-number texts are harmless. Some are the first step in a carefully planned scam. By replying, you may be confirming that your number is active and that you’re willing to engage with strangers, making you a more valuable target for future fraud. Here’s why a polite response can be worth money to cybercriminals. The politeness trap Sunday night. You’re on the couch, half-watching Netflix, when your phone buzzes. “Hey! Are we still on for dinner tomorrow? Don’t forget the wine ” You…

Research by: Jaromír Hořejší (@JaromirHorejsi) Key points StopAndProtect is a newly identified operation that combines file encryption with data theft. The criminals abuse thousands of hacked WordPress websites as their infrastructure – using them to spread the malware, control infected machines, and store stolen documents, screenshots, and activity logs (records created by malware to track its actions, progress, or status during execution). Operational security (OPSEC) failures by the…
Welcome to this week’s edition of the Threat Source newsletter. “Experiment is the mother of knowledge.” ― Madeleine L'Engle, A Wrinkle in Time“Don't slide down the rabbit hole.

Researchers at Group-IB have discovered a new NFC relay malware family, purpose-built to capture live card data via NFC and forward it in real time to attackers. They dubbed it “WindRelay.” NFC (Near Field Communication) is wireless technology that allows devices such as smartphones, payment cards, and payment terminals to communicate when they’re very close together. So, instead of stealing your physical bank card, the attackers capture NFC activity on an infected mobile phone and relay it in…
Cisco Talos recently identified an undocumented phishing framework, internally branded "JWR" by its developer, built to convincingly impersonate checkout and login pages across major payment and shopping platforms. The client engine of the JWR phishing framework is a real-time, operator-driven system that, rather than merely logging form submissions like a static credential-stealing page, keeps an AES-CTR encrypted WebSocket open to the threat actor so they can steer each victim's session live.…

Have you ever read the Talos IR Quarterly Trends report and wondered, “How did that phishing or ransomware campaign actually play out? When was Talos IR contacted, how did they contain it, and how did they remediate the environment?" You’re in luck. Next Tuesday, August 11, Cisco Talos Incident Responders will be hosting an exclusive, unrecorded 30-minute webinar to review the most high-impact incidents our customers faced in Q2 2026. This isn’t a rehashing of the report itself, but a candid…

Welcome to this week’s edition of the Threat Source newsletter. For my fianceé’s 30th birthday, I took her on a weekend trip to Shenandoah National Park – a favorite of ours since we went to a wedding there several years back. We’ve done several incredible hikes over the years, but one in particular had always loomed over my head: Old Rag, a 9.3 mile circuit hike that’s largely considered the most difficult in Virginia. I've always been warned that at the beginning and end, you hate Old Rag.…
Elastic Security Labs found a new Contagious Interview campaign, tracked as REF9403, hiding malware inside SVG image files using steganography. To our knowledge, this specific infection chain has not been previously documented. We found it after the DPRK-aligned group targeted our own community Slack workspace with a fake job posting and a "coding challenge" project. Any user who ran the project ended up with a four-stage payload aligned with OTTERCOOKIE: a browser credential and crypto wallet…

Elastic Security Labs is tracking an emerging threat named TELEPUZ, which we have discovered spreading widely via a CLICKFIX-VIDAR chain. This malware is in active development and has been operating since late April 2026, according to the infrastructure information we collected. The malware is full-featured, lightweight, and modular. While the number of C2 domains is currently small, the daily volume of builds uploaded to VirusTotal and the rapid pace of updates indicate active development and…
For years, the cyber security industry tracked AI as a force multiplier: something that made existing attack techniques faster, cheaper, and more accessible. That framing was accurate. But the Annual AI Security Report 2026 from Check Point Research documents a transition that goes further. AI has crossed from assistant to operator. Where it once helped attackers prepare, it now runs the operation. Key observed findings AI has crossed from development aid to live attack operator. It now does…

A Mexican banking fraud operation we're tracking as REF6045 doesn't run on autopilot. A human operator is behind the wheel, monitoring infected machines and deciding what happens next. Victims are infected through fake CAPTCHA pages that trick them into running a single command, which installs SCMBANKER, a PowerShell toolkit with components dating back to at least October 2025. Once installed, the operator can see when a victim opens a banking session, lock the screen behind a fake bank warning…

FortiGuard Labs research shows how cybercriminals are exploiting the demand for the FIFA World Cup 2026 through phishing, fake tickets, malware, impersonation, and credential theft.
With the 2026 FIFA World Cup just weeks away, Group-IB researchers have uncovered six distinct fraud schemes, four independent threat actors, and over 4,300 fraudulent domains impersonating FIFA's official web presence — including a sophisticated phishing operation run by the Chinese-speaking threat actor GHOST STADIUM, whose campaign could cause losses reaching billions of dollars.
Tycoon 2FA is currently the most prolific Phishing-as-a-Service (PhaaS) platform among AiTM phishing kits. First observed in August 2023 and attributed to Storm-1747 (per Microsoft Threat Intelligence), the kit provides turnkey adversary-in-the-middle (AiTM) capabilities that bypass multi-factor authentication and steal authenticated session tokens from Microsoft 365 and Google Workspace accounts. At its peak, Tycoon 2FA accounted for roughly 62% of phishing attempts blocked by Microsoft,…

Introduction Elastic Security Labs is observing malicious campaigns delivering a multi-stage infection involving a previously undocumented loader. The infection begins when users are diverted to a Cloudflare Turnstile CAPTCHA page under the guise of a digital invitation. After the link is clicked, a VBScript file is downloaded to the machine. Upon execution, the script retrieves C# source code, which is then compiled and executed in memory using PowerShell. The final payload observed in these…
