⚠️ Kaspersky reports a patched Google Chrome zero-day (CVE-2025-2783) was exploited to deploy a newly documented spyware called LeetAgent linked to Italian firm Memento Labs. The operation used personalized, short‑lived phishing links to a Primakov Readings lure that triggered a sandbox escape in Chromium browsers and dropped a loader to launch the implant. Targets included media, universities, research centers, government and financial organizations in Russia and Belarus.

🛡️ Trellix researchers report that the threat actor SideWinder has evolved its tradecraft in 2025 by adopting a PDF + ClickOnce infection chain alongside previously used Word exploit vectors. Four spear‑phishing waves from March through September targeted a European embassy in New Delhi and organizations in Sri Lanka, Pakistan and Bangladesh, using tailored lures and a signed MagTek executable that side‑loads a malicious DLL. The DLL decrypts and runs a .NET loader (ModuleInstaller) which fetches StealerBot, a .NET implant capable of reverse shells, delivering additional payloads, and collecting screenshots, keystrokes, credentials and files.

🔒 Google says reports of a massive Gmail data breach are false and that the coverage mischaracterizes a large compilation of exposed credentials. The 183 million-account figure reflects aggregated infostealer databases and credential dumps compiled over years, not a single Gmail compromise. Troy Hunt added the dataset to Have I Been Pwned, which found 91% of entries were previously seen; 16.4 million addresses were newly observed. Users should check their accounts, run antivirus scans, and change any compromised passwords.

🔒 Cisco Talos reports that Qilin ransomware sustained a surge through the second half of 2025, publishing more than 40 victim listings per month on its leak site and peaking at roughly 100 postings in June and August. The group uses a double-extortion model, encrypting systems and threatening to publish stolen data if ransoms are not paid. Operating as a RaaS, Qilin and its affiliates have heavily targeted manufacturing, professional/scientific services and wholesale trade. Investigators observed use of Cyberduck, standard Windows utilities for file viewing, and dual encryptors that spread laterally via PsExec and encrypt multiple network shares.

🔍 Our GReAT team reconstructed ForumTroll’s infection chain and identified the malware family dubbed LeetAgent, delivered via spear‑phishing and an exploit of CVE-2025-2783 in Google Chrome when recipients were lured with invitations to the Primakov Readings. Further analysis linked the same delivery tools to the commercial spyware Dante (formerly developed by Hacking Team, now Memento Labs), which uses modular plugins, per‑victim encryption keys and a timed self‑destruct mechanism. Initial detections were made by Kaspersky XDR; full technical details and IOCs have been compiled for APT subscribers.

🔍 The theft at the Louvre—where four thieves used an electric ladder, an angle grinder and seven minutes to remove jewels from the Apollo Gallery—exposed stark security lapses. A single outdoor camera pointed away from the balcony left no interior footage, and guards appeared focused on patrons rather than valuables. Arrests have been reported, but the pieces' likely disassembly will greatly reduce their recoverable value.

🔐 A Hiscox survey of 1,000 mid-sized firms finds ransomware remains a major risk: 27% of organizations reported attacks in the past year and 80% of victims paid ransom. Yet only 60% of those who paid recovered data fully or partially. Experts cite faulty encryptors, unreliable decryptors, corrupted backups and double/triple extortion as common causes. Industry specialists recommend tested recovery plans, retainers with incident response teams, and robust cyber insurance rather than relying on ransom payments.

🔒 Europol, together with police in Estonia, Finland, Latvia and Austria, dismantled a cybercrime-as-a-service network during coordinated raids on October 10. Seven suspects were arrested and authorities seized five servers, some 40,000 active SIM cards, luxury vehicles, bank accounts and crypto wallets. Investigators say the operation created roughly 49 million fake accounts across about 80 countries and used those identities to swindle millions of euros.

⚠️ Microsoft released an out-of-band patch for a critical WSUS remote code execution (CVE-2025-59287) after researchers observed active exploitation that drops a .NET executable and Base64 PowerShell payloads. LockBit has resurfaced with a new multi-platform 5.0 variant claiming victims, while a modified Telegram Android app distributing the Baohuo backdoor has infected tens of thousands of devices. Reporting also shows the F5 breach began in late 2023 and has since widened, underscoring the need for urgent patching and threat hunting.

📰 Tata Consultancy Services has denied reports that it lost a service desk contract with Marks & Spencer following the retailer’s April cyber-attack. In an October 26 regulatory filing to Indian stock exchanges, TCS described a Telegraph article as "misleading" and pointed to "factual inaccuracies", saying the RFP to evaluate suppliers began in January 2025 and concluded before the incident. TCS said it continues to hold other active contracts with M&S, that a June investigation found no vulnerabilities originating in TCS networks, and that it does not provide cybersecurity services to the retailer.

🛡️ Trend Micro reports that the Agenda (Qilin) ransomware group is running a Linux-based encryptor on Windows hosts to evade Windows-only detections. The actors abused legitimate RMM and file-transfer tools — including ScreenConnect, Splashtop, Veeam, and ATERA — to maintain persistence, move laterally, and execute payloads. They combined social engineering, credential theft, SOCKS proxy injection, and BYOVD driver tampering to disable EDR and compromise backups, impacting more than 700 victims since January 2025.

🔒 Qilin (aka Agenda, Gold Feather, Water Galura) has sharply increased operations in 2025, claiming dozens of victims monthly and peaking at 100 leak-site postings in June. Cisco Talos and Trend Micro analyses show affiliates gain initial access via leaked admin credentials, VPN interfaces and RDP, then harvest credentials with tools like Mimikatz and SharpDecryptPwd. Attackers combine legitimate remote-management software (for example AnyDesk, ScreenConnect, Splashtop) with a BYOVD vulnerable driver to disable defenses, exfiltrate data, and deploy a Linux ransomware binary on Windows systems before encrypting files and removing backups.

🔐 Datadog Security Labs has described a new phishing technique called CoPhish that abuses Copilot Studio agents to present fraudulent OAuth consent requests on legitimate Microsoft-hosted demo pages. Attackers can configure an agent’s Login topic to deliver a malicious sign-in button that redirects to a hostile application and exfiltrates session tokens. Microsoft confirmed it will address the underlying causes in a future update and recommends governance and consent hardening to reduce exposure.

⚠️ LastPass customers are being targeted by a phishing campaign that falsely notifies recipients that a family member uploaded a death certificate to request legacy access. Messages spoof the LastPass domain and include a cancellation link that redirects to an attacker-controlled site asking for the master password. Some victims have also received phone calls pressing the same ruse. LastPass warns it never asks for master passwords and has removed the initial phishing site.

📱 Unit 42 attributes a sprawling smishing campaign to the China-linked Smishing Triad, tying it to 194,345 FQDNs and more than 194,000 malicious domains registered since January 1, 2024. Most root domains are registered through Dominet (HK) Limited yet resolve to U.S.-hosted infrastructure, primarily on Cloudflare (AS13335). Campaigns impersonate USPS, toll services, banks, exchanges and delivery services, using rapid domain churn to evade detection. The operation has reportedly generated over $1 billion in three years and increasingly targets brokerage and banking accounts to enable market manipulation.

🔒 After months of rumored silence, security researchers have identified multiple organizations hit by LockBit-branded ransomware in September 2025. Check Point's report documents about a dozen victims across Western Europe, the Americas and Asia, affecting both Windows and Linux systems. Roughly half were infected with LockBit 5.0 and the rest with the leaked 3.0 (LockBit Black) variant. LockBit 5.0 introduces multi-platform builds, enhanced anti-analysis, randomized extensions and a revamped affiliate panel requiring a roughly $500 deposit.

🔒 LastPass warns customers of a sophisticated phishing campaign that uses fake inheritance emails claiming a family member uploaded a death certificate to request emergency access to a user's vault. The messages include an agent ID and a link that redirects victims to a fraudulent page on lastpassrecovery[.]com where the victim is prompted to enter their master password. In some incidents attackers also called victims while posing as LastPass staff. The campaign, active since mid‑October and attributed to financially motivated group CryptoChameleon (UNC5356), has expanded to target passkeys as well.

🔐 Sekoia observed Transparent Tribe (APT36) conducting spear-phishing campaigns in Aug–Sep 2025 that deliver a Golang remote access trojan dubbed DeskRAT. The attacks use ZIP attachments containing malicious .desktop files that display a decoy PDF while executing the payload, specifically targeting BOSS Linux systems. DeskRAT establishes WebSocket C2, supports multiple persistence mechanisms, and includes modules for harvesting and exfiltrating WhatsApp and Chrome data. Researchers also reported the use of "stealth servers" and a shift from cloud-hosted distribution to dedicated staging infrastructure.

🔒SentinelOne reported a one-day spear-phishing campaign on October 8 that targeted aid organisations and Ukrainian regional administrations. The operation, named PhantomCaptcha, delivered a WebSocket RAT hosted on Russian-owned infrastructure and used weaponized PDFs and a fake Cloudflare CAPTCHA to trick victims into executing PowerShell. The multi-stage chain enabled data exfiltration, persistent remote access and potential deployment of additional malware.

📡 ESET researchers have uncovered a new Lazarus Group espionage campaign targeting European defense contractors, with a focus on companies involved in unmanned aerial vehicle (UAV) development since March 2025. The attackers used spear-phishing with fake job offers and trojanized open-source tools such as WinMerge and Notepad++ to deliver loaders and the custom RAT ScoringMathTea. The intrusion chain relied on DLL side-loading, reflective loading, and process injection to maintain persistence and exfiltrate design and supply-chain data. ESET has published IoCs and MITRE ATT&CK mappings to help defenders respond.
