ESET identified a previously unknown Russian‑linked hacking group, Gorbag, that has been phishing Ukrainian agencies to steal documents, credentials and VPN data. The actors use the BeautyStealer and Prime ReverseShell tools and have recently leveraged the patched WinRAR CVE‑2025‑8088 vulnerability.
Key points
- Gorbag, a Russia‑aligned espionage group, has been targeting Ukrainian law‑enforcement, local governments, defense bodies and a key foreign‑military‑aid transport hub.
- The group relies on phishing emails with malicious attachments and employs the BeautyStealer data‑stealer and Prime ReverseShell remote‑execution tool.
- In early 2026 Gorbag began exploiting CVE‑2025‑8088 in WinRAR, a vulnerability that was patched in July 2025.
- ESET notes the group’s quick‑hit approach suggests they may hand off stolen credentials to other actors for deeper intrusions.
Barracuda disclosed a pre‑auth authorization bypass (CVE‑2026‑116606) and a command‑injection flaw (CVE‑2026‑111560) that together could let attackers reach root on affected devices. The bugs affect multiple Barracuda security appliances and require access to the admin interface. Customers are urged to apply the latest firmware and restrict admin access.
Key points
- A pre‑authentication authorization bypass (CVE‑2026‑116606, CVSS 9.3) impacts the Email Security Gateway.
- A command‑injection flaw (CVE‑2026‑111560, CVSS 8.6) affects six Barracuda products including the Email Security Gateway, Load Balancer ADC, and Web Application Firewall.
- Exploitation requires prior access to the product’s administrative console; chaining the bugs can bypass controls and achieve root.
- Barracuda advises limiting admin interface exposure and installing the latest firmware patches.
- No public exploits are reported, but patches are already available.
Synology reports that threat actors are leveraging a December 2024 patched DSM flaw to launch ransomware attacks against outdated NAS devices. The company urges immediate updates to the latest DSM versions to mitigate the risk.
Key points
- Synology observed ransomware campaigns targeting NAS units running older DSM versions despite a December 2024 patch.
- The attacks use the C3RB3R ransomware, which encrypts files with a ".L0CK3D" extension and demands ransom.
- Three CVEs (CVE-2024-10441, CVE-2024-50629, CVE-2024-10445) were patched in DSM 7.2.2 and earlier releases.
- Synology recommends upgrading to the latest DSM releases and enabling automatic updates to prevent compromise.
Europol announced the arrest of seven suspects linked to an investment scam that targeted victims in more than 50 countries and caused at least $4.5 million in losses. The operation seized over 100 servers and involved coordinated searches across 17 nations. The scheme used fraudulent trading sites and call‑center affiliates to lure victims into transferring funds.
Key points
- Seven individuals were detained in a coordinated raid spanning 17 countries.
- Authorities seized more than 100 servers used to host fake trading platforms.
- The scheme operated from Cyprus and Israel, with call‑centers in the Balkans.

OPSSHIELD disclosed that attackers compromised the cPGuard update system on Nov 2, injecting a script into versions 5.88.12‑5.88.19 that installed a backdoor and exfiltrated password hashes and other sensitive files. Updated releases 5.88.25+ remove the malicious code, but affected servers must rotate credentials.
Key points
- The attacker accessed cPGuard’s update infrastructure using stolen credentials and pushed a malicious script to customers’ Linux servers.
- The script installed a backdoor, collected /etc/shadow, /etc/passwd, MySQL configs, shell history, and SSH keys, and uploaded the data to OPSSHIELD’s licensing server.
- OPSSHIELD released an advisory and fixed the issue in cPGuard 5.88.25, urging admins to update, reset passwords, rotate secrets, and replace SSH keys.
- At least 32 files tied to individual customer servers were confirmed taken, though the total number of impacted servers is unknown.
- The compromise highlights risks of supply‑chain attacks on security‑tool update channels.

LLMjacking exploits compromised LLM API keys to generate massive cloud charges, costing some firms up to $1 M.
Key points
- Google identifies LLMjacking as a new resource‑hijacking technique where attackers obtain LLM API keys via phishing, leaked code, or misconfigured cloud assets.
- The most common initial access vectors are stolen IAM tokens, Service Account keys, and GitHub personal access tokens, exemplified by actor UNC6993.
- Fraudulent usage can spike to over $100 k in a single day, with cumulative losses of up to $1 M before remediation.
- Attackers enumerate cloud services, create backdoor service accounts, and exploit vulnerabilities such as CVE‑2026‑40217 in LiteLLM to maintain persistence.
- Google and Mandiant warn that the abuse targets multiple sectors worldwide, including finance, retail, technology, and transportation.

Kaspersky details an AI‑orchestrated campaign using the open‑source CyberStrikeAI framework against education sector targets.
Key points
- The campaign leverages a Go‑based open‑source tool, CyberStrikeAI, which combines a large language model orchestrator with a traditional C2 agent to automate reconnaissance, lateral movement, and data exfiltration.
- Initial access is achieved via a compromised SQL Server, after which the AI‑driven agent takes over to plan and execute subsequent steps without direct human command for each action.
- Artifacts such as the process "not_before" timestamp, Go build metadata, and a fixed X‑Implant‑Token header enable detection and attribution of the framework’s instances.
- Kaspersky notes this is among the first documented instances of an LLM being embedded in the post‑exploitation phase of a real‑world attack.
A supply‑chain malware and fake interview campaign enabled thieves to steal $6.43 billion from Binance’s wallet service.

A fake-download campaign uses trojanized Inno Setup installers to install proxy, compute‑resource and adware payloads without user consent.
Key points
- The campaign targets users searching for cracked software, games, activators and utilities, delivering trojanized Inno Setup installers.
- Installers create temporary runners in %TEMP% and execute numbered stages that report back via offer‑execution callbacks.
- Based on the callback, one or more monetization branches are installed: WorldProxyPool (proxy traffic), BOINC‑based compute platforms, or adware utilities like Advanced Windows Manager.
- Installed components may set scheduled tasks, route traffic, or join distributed‑computing networks, posing security and privacy risks.
- Microsoft recommends blocking untrusted sources, enabling potentially unwanted application protection, and using advanced hunting queries to detect activity.
Polymarket will refund $3.9 million after a compromised third‑party script stole cryptocurrency from user wallets.
