NPM package uses QR code to fetch cookie-stealing malware

🔒 A malicious npm package named fezbox was recently discovered using a QR code embedded in an image to retrieve a second-stage, cookie-stealing payload from the attacker's server. The package's minified code (notably in dist/fezbox.cjs) delays execution, avoids development environments, then decodes a reversed URL to fetch a dense JPG QR image containing obfuscated JavaScript. When the payload finds credentials in document.cookie it extracts username and password and exfiltrates them via an HTTPS POST; the package accrued at least 327 downloads before registry removal.

Attacker Breakout Time Drops to 18 Minutes, ReliaQuest

🔒 ReliaQuest's Threat Spotlight (June–August 2025) reports average attacker breakout time — the period from initial access to lateral movement — has fallen to 18 minutes, with one Akira incident taking just six minutes. The vendor warns adversaries are becoming faster and more adept at bypassing endpoint protections, noting an increase in ransomware using the SMB protocol (from 20% to 29%). Drive-by compromise was the leading initial vector at 34%, and USB-based malware, notably Gamarue, is resurging due to weak policy enforcement and inconsistent endpoint controls.

LastPass Alerts: Fake GitHub Repos Deliver macOS Infostealer

🛡️ LastPass warns of a widespread campaign leveraging fake GitHub repositories and SEO-poisoned search results to distribute an Atomic-infostealer targeting macOS users. The malicious pages impersonate popular tools such as LastPass, 1Password, and Dropbox, and redirect victims to pages that instruct them to run Terminal commands. Those commands fetch and execute a multi-stage dropper that deploys the Atomic Stealer. Users should verify official vendor pages and avoid running untrusted commands in Terminal.

ShadowLeak: Zero-click flaw exposes Gmail via ChatGPT

🔓 Radware disclosed ShadowLeak, a zero-click vulnerability in OpenAI's ChatGPT Deep Research agent that can exfiltrate sensitive Gmail inbox data when a single crafted email is present. The technique hides indirect prompt injections in email HTML using tiny fonts, white-on-white text and CSS/layout tricks so a human user is unlikely to notice the commands while the agent reads and follows them. In Radware's proof-of-concept the agent, once granted Gmail integration, parses the hidden instructions and uses browser tools to send extracted data to an external server. OpenAI addressed the issue in early August after a responsible disclosure on June 18, and Radware warned the approach could extend to many other connectors, expanding the attack surface.

Iran-linked UNC1549 Compromises 34 Devices in Telecoms

🔒 PRODAFT links a recruitment-themed espionage campaign to an Iran-affiliated cluster tracked as Subtle Snail and attributed to UNC1549 (aka TA455), reporting infiltration of 34 devices across 11 telecommunications organizations in Canada, France, the UAE, the UK and the US. Operators posed as HR recruiters on LinkedIn and delivered a ZIP-based dropper that uses DLL side-loading to install the modular backdoor MINIBIKE, which harvests credentials, browser data, screenshots, keystrokes and system details. MINIBIKE communicates with C2 infrastructure proxied through Azure services, employs anti-analysis measures and achieves persistence via registry modifications to enable long-term access and data exfiltration.

Lucid, first documented by PRODAFT in April, supports smishing via Apple iMessage and RCS and is tied to the Chinese-speaking XinXin group. Both services offer customizable templates, real-time victim monitoring, and granular targeting controls (User-Agent, proxy country, configured paths) that restrict access to intended victims. Lighthouse subscriptions run from $88 per week to $1,588 per year, underscoring the commercial scale of these offerings.

Gamaredon and Turla Collaborate in Attacks on Ukraine

🕵️ ESET researchers report that Russian state-linked groups Gamaredon and Turla collaborated in 2025 campaigns targeting high-value Ukrainian defense systems. In February, investigators observed Turla issuing commands via Gamaredon implants and Gamaredon's PteroGraphin downloader being used to restart Turla's Kazuar backdoor. Kazuar harvested machine metadata while Gamaredon later deployed Kazuar v2 installers in April and June. ESET assesses with high confidence that the interactions reflect a deliberate operational convergence.

ShadowLeak zero-click exfiltrates Gmail via ChatGPT Agent

🔒 Radware disclosed a zero-click vulnerability dubbed ShadowLeak in OpenAI's Deep Research agent that can exfiltrate Gmail inbox data to an attacker-controlled server via a single crafted email. The flaw enables service-side leakage by causing the agent's autonomous browser to visit attacker URLs and inject harvested PII without rendering content or user interaction. Radware reported the issue in June; OpenAI fixed it silently in August and acknowledged resolution in September.

Gamaredon and Turla Collaborate to Deploy Kazuar Backdoor

🔒ESET researchers observed tools from Russian-linked groups Gamaredon and Turla cooperating to deploy the .NET-based Kazuar backdoor on multiple Ukrainian endpoints in early 2025. Gamaredon delivered PowerShell downloaders — PteroGraphin, PteroOdd and PteroPaste — which retrieved Kazuar payloads via Telegraph, Cloudflare Workers domains and direct IP hosting. Analysts assess with high confidence that Gamaredon provided initial access while Turla leveraged the access for espionage, primarily targeting Ukrainian defense-sector assets.

CISA Details Two Java Loaders Exploiting Ivanti EPMM Flaws

🔒 CISA released details of two malicious toolsets found on an organization's server after attackers chained zero-day vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM). Each set contains a Java loader that installs an HTTP listener to decode, decrypt and execute arbitrary payloads and maintain persistence. CISA urges updating EPMM, monitoring for suspicious activity, and restricting access to MDM systems.

ShadowLeak: AI agents can exfiltrate data undetected

⚠️Researchers at Radware disclosed a vulnerability called ShadowLeak in the Deep Research module of ChatGPT that lets hidden, attacker-crafted instructions embedded in emails coerce an AI agent to exfiltrate sensitive data. The indirect prompt-injection technique hides commands using tiny fonts, white-on-white text or metadata and instructs the agent to encode and transmit results (for example, Base64-encoded lists of names and credit cards) to an attacker-controlled URL. Radware says the key risk is that exfiltration can occur from the model’s cloud backend, making detection by the affected organization very difficult; OpenAI was notified and implemented a fix, and Radware found the patch effective in subsequent tests.

Palo Alto Acknowledges Browser-Malware Risks, Validates LMR

🔍 SquareX’s Last Mile Reassembly (LMR) research, disclosed at DEF CON 32, shows how attackers split and reassemble malware inside the browser to evade Secure Web Gateways (SWGs). Palo Alto Networks has become the first major SASE vendor to publicly acknowledge this class of browser-assembled evasive attacks and announced enhancements to Prisma Browser. SquareX says LMR and related Data Splicing techniques exploit channels like WebRTC and gRPC, bypassing traditional SWG and DLP controls and underscoring the need for browser-native security.

CountLoader Expands Use by Russian Ransomware Groups

Appearing in .NET, PowerShell and JavaScript flavors, the loader has been observed in PDF phishing campaigns targeting Ukraine and employs LOLBins and multiple download/execution methods to evade detection. The JavaScript variant is most feature‑complete, offering diverse downloaders, execution paths and persistence via a Google‑update‑named scheduled task.

Malware Distributed Through Trusted Gaming Resources

🎮 Several incidents show attackers distributing malware via trusted gaming channels, including a compromised Endgame Gear OP1w utility, infected early-access Steam titles, and malicious skins on the official Minecraft site. The Endgame Gear installer likely contained the XRed backdoor, while Steam cases involved infostealers such as Trojan.Win32.Lazzzy.gen that harvested cookies and credentials. Users suffered account takeovers and data loss; recommended defenses include up-to-date antivirus, cautious vetting of downloads, and using gaming security modes that minimize disruption.

TA558 Deploys AI-Generated Scripts to Install Venom RAT

⚠️Kaspersky tracked TA558, operating under the cluster known as RevengeHotels, using AI-generated JavaScript and PowerShell loaders in summer 2025 to deliver Venom RAT to hotels in Brazil and Spanish-speaking markets. Phishing emails in Portuguese and Spanish used reservation and job-application lures to coax users into running a WScript payload that chains to a PowerShell downloader fetching 'cargajecerrr.txt' and subsequent loaders. The Venom RAT, based on Quasar, includes data-stealing, reverse-proxy, persistence and aggressive anti-kill features aimed at harvesting payment card data from hotel systems and OTAs.

FileFix Campaign Uses Steganography and Multistage Payloads

🛡️ Acronis researchers have uncovered a rare FileFix campaign that hides a second-stage PowerShell script and encrypted executables inside JPG images using steganography. Attackers employ multilingual, heavily minified phishing pages that mimic a Meta support flow and trick victims into pasting a payload into file upload address bars. An obfuscated PowerShell one-liner downloads images from Bitbucket, extracts and decrypts components, and executes a Go-based loader that deploys StealC. Organizations should combine user training with process blocking and monitoring to mitigate this evolving threat.

Chinese TA415 Abuses VS Code Remote Tunnel for Espionage

🔒 Proofpoint reported that a China-aligned threat actor tracked as TA415 conducted spear-phishing in July–August 2025, impersonating U.S. policy officials and the U.S.-China Business Council to target government, think tank, and academic personnel focused on trade and economic policy. The messages delivered password-protected archives on public cloud services that contained a Windows shortcut which executed a hidden batch script and an obfuscated Python loader named WhirlCoil while displaying a decoy PDF. The loader establishes a VS Code Remote Tunnel to enable persistent backdoor access, harvests system and user data, exfiltrates it via base64-encoded HTTP posts to free request-logging services, and establishes scheduled tasks (e.g., GoogleUpdate) for persistence.

Scattered Spider Resurfaces, Targets Financial Sector Again

🔍 Cyber threat group Scattered Spider has been linked to a new campaign targeting financial services, according to ReliaQuest. The attackers gained access by socially engineering an executive and abusing Azure AD self-service password reset, then moved laterally via Citrix and VPN to compromise VMware ESXi. They escalated privileges by resetting a Veeam service account, assigning Azure Global Administrator rights, and attempted data extraction from Snowflake and AWS. The activity contradicts the group's retirement claims and suggests regrouping or rebranding.
