📢 Researchers report that the Predator spyware operator Intellexa developed a zero-click delivery mechanism called Aladdin that can infect targets simply by serving a weaponized advertisement. The technique abuses commercial mobile advertising systems and Demand Side Platforms to force malicious ads to specific IPs and devices, with viewing alone triggering redirections to exploit servers. First deployed in 2024 and routed through shell companies across multiple countries, the campaign is corroborated by leaked Intellexa documents and technical analysis from Amnesty, Google, and Recorded Future. Analysts recommend blocking ads, hiding public IPs, and using platform protections, though leaked materials suggest operators can obtain subscriber IP/location data from local mobile operators.

🚨 ReliaQuest attributes a false-flag SEO poisoning campaign to the actor known as Silver Fox, which has been active since November 2025 and aims to masquerade as a Russian group to mislead investigators. The campaign pushes a malicious Teams installer packaged as "MSTчamsSetup.zip" from an Alibaba Cloud URL, drops a trojanized Setup.exe, establishes exclusions in Microsoft Defender, and writes a staged installer "Verifier.exe" to the AppData profile. The loader scans for security processes, injects a malicious DLL into rundll32.exe, and reaches out to a remote server to retrieve the final ValleyRAT payload.

🧾 Two Virginia brothers, former federal contractors Muneeb and Sohaib Akhter, have been charged with conspiring to steal sensitive data and deleting roughly 96 government databases after being fired. Prosecutors allege the deletions occurred in February 2025 and that Muneeb also stole IRS and EEOC information for hundreds of individuals. One minute after deleting a DHS database he reportedly asked an AI tool how to clear system logs. Authorities say the pair wiped devices, destroyed evidence, and face multiple federal charges including computer fraud and aggravated identity theft.

🔍 A newly discovered phishing framework named GhostFrame has been linked to more than one million attacks, according to Barracuda. The kit uses a benign-looking outer HTML page that conceals a malicious iframe, enabling attackers to swap content, target regions and evade scanners without changing the visible landing page. GhostFrame employs a two-stage chain: the loader creates randomized subdomains and validates them before loading an internal credential-stealing page, and includes anti-analysis controls that block inspection shortcuts and restrict user actions. Barracuda recommends a multilayered defense—regular browser updates, staff training, email gateways and web filters, restricting iframe embedding, and monitoring for injected or redirected content.

🔔 Momberger – Lack & Technik warns customers of a targeted email fraud campaign that began on December 1. The company says unauthorized access to an email account was used to send forged messages requesting payment of fictitious invoices; only existing customer addresses were targeted. Momberger urges recipients not to pay, open links, or attachments, and says systems have been secured while additional protections and authorities are involved.

🔒FortiGuard Labs reports multiple campaigns deploying the UDPGangster UDP-based backdoor, attributed to the MuddyWater espionage group. Attackers used macro-embedded Microsoft Word documents delivered via phishing, impersonating official Turkish emails and targeting users in Turkey, Israel, and Azerbaijan. The malware implements persistence, extensive anti-analysis checks, and UDP C2 communications to exfiltrate data and execute remote commands. Fortinet detections and protections are available to mitigate these threats.

🔒 CISA warns that PRC state-sponsored actors are deploying the BRICKSTORM backdoor to maintain stealthy, long-term access on VMware vSphere and Windows hosts. The malware leverages nested TLS/WebSockets, DNS-over-HTTPS, and a SOCKS proxy for encrypted C2, lateral movement, and tunneling, and implements a self‑healing persistence mechanism. CISA urges defenders to hunt with provided YARA/Sigma rules, block unauthorized DoH, inventory edge devices, and enforce DMZ segmentation.

🔒This week's ThreatsDay roundup highlights a string of high-impact incidents, from a $9 million DeFi drain and an npm-based self-replicating worm to airport Wi‑Fi evil‑twin attacks and mass camera compromises. Researchers and vendors including Fortinet, Microsoft, and TruffleHog disclosed evolving malware techniques, supply-chain abuse, and widespread credential exposure. Practical protections include minimizing long-lived secrets, enforcing CI/CD safeguards, updating detection for eBPF-based threats, and applying MFA and phishing-resistant controls.

🔒 The Information Commissioner's Office found that an unredacted settlement document related to the long-running Horizon scandal exposed the names, home addresses and postmaster status of 502 litigants on the Post Office website between 25 April and 19 June 2024. The ICO considered a fine just under £1.1m but issued a reprimand under its public sector approach after concluding the breach was not 'egregious'. The regulator criticised the Post Office for lacking documented publishing policies, quality assurance and sufficient staff training; the organisation has offered compensation and 24 months of identity protection and taken steps to remove cached copies and strengthen controls.

🛡️ Group-IB says the financially motivated actor GoldFactory has launched a new campaign across Indonesia, Thailand, and Vietnam, distributing modified Android banking apps that serve as droppers for remote‑access trojans. The campaign, active since October 2024 and linked to activity as far back as June 2023, relies on phone-based social engineering and messaging apps like Zalo to direct victims to fake Play Store landing pages. Injected modules preserve normal banking functionality while hooking app logic to bypass security checks, abuse accessibility services, and exfiltrate credentials and account balances.

🚨 Cloudflare reported it detected and mitigated a record 29.7 Tbps distributed denial-of-service attack attributed to the AISURU botnet. The UDP "carpet-bombing" assault, which randomized packet attributes and targeted an average of 15,000 destination ports per second, lasted 69 seconds. Cloudflare also mitigated a 14.1 Bpps event and said AISURU may comprise 1–4 million infected hosts, while blocking thousands of related hyper-volumetric attacks and noting significant quarterly increases in DDoS activity.

🔍 CrowdStrike identified a China-nexus adversary, WARP PANDA, conducting covert intrusions against VMware vCenter and cloud infrastructure throughout 2025, deploying novel Golang implants and the backdoor BRICKSTORM. Operations emphasized stealth—log clearing, timestomping, unregistered VMs, and tunnelling via vCenter/ESXi/guest VMs—enabling long-term persistence and data staging from live VM snapshots. WARP PANDA also exfiltrated Microsoft 365 and SharePoint content, registered MFA devices, and abused cloud services for C2, prompting recommendations for tighter ESXi/vCenter controls and robust EDR on guests.

🔒 Financial software provider Marquis Software Solutions disclosed a ransomware intrusion on August 14, 2025, after attackers breached a SonicWall firewall and exfiltrated certain files. The incident potentially impacted roughly 400,000 customers across 74 banks and credit unions and involved names, contact details, Social Security and Taxpayer IDs, account information (no security codes), and dates of birth. Marquis says there is no confirmed misuse or publication of the data to date and is notifying affected institutions and state regulators while implementing enhanced security measures, including MFA, patching, account cleanup, and tightened firewall policies.

🔔 French home improvement retailer Leroy Merlin has notified customers in France that certain personal data may have been exposed in a cyberattack, including full names, phone numbers, email and postal addresses, dates of birth and loyalty program details. The company says no banking data or account passwords were involved and that it moved quickly to block unauthorized access and contain the incident. The notice warns customers to be vigilant against phishing and impersonation attempts; BleepingComputer confirmed the notification is genuine and has sought further details. No ransomware group had claimed responsibility at the time of reporting.

🔒 Freedom Mobile detected a breach of its customer account management platform on October 23 after a third party used the account of a subcontractor to access customer records. The carrier says it blocked suspicious accounts and IP addresses and implemented corrective measures and security enhancements. Exposed data include first and last names, home addresses, dates of birth, phone numbers, and Freedom account numbers. Freedom reports no evidence so far of misuse and has urged customers to watch for phishing and check accounts for unusual activity.

📧 Sekoia.io researchers have identified a fresh wave of spear-phishing linked to the Russia-nexus intrusion set Star Blizzard (aka Calisto/ColdRiver) that targeted NGOs including Reporters Without Borders in May–June 2025. Operators impersonated trusted contacts via ProtonMail, using a custom Adversary-in-the-Middle kit to harvest credentials and relay 2FA prompts through compromised sites and redirectors. Observed tactics included a ZIP disguised as a .pdf, decoy encrypted PDFs instructing victims to open files in ProtonDrive, injected JavaScript to lock password-field focus, and an API-driven workflow for handling CAPTCHA and 2FA challenges, underscoring continued risk to Western organizations supporting Ukraine.

🔒 Water Saci has shifted to a layered infection chain that uses HTA files and malicious PDFs delivered via WhatsApp to deploy a banking trojan in Brazil. The actors moved from PowerShell to a Python-based worm that propagates through WhatsApp Web, while an MSI/AutoIt installer and process-hollowing techniques load the trojan only on Portuguese (Brazil) systems. Trend Micro links the behavior to Casbaneiro-style features and notes possible use of code-translation or AI tools to port scripts. In parallel, a React Native Android strain named RelayNFC executes real-time NFC APDU relays to enable contactless payment fraud.

⚠️ A vulnerability in Yearn Finance's yETH pool allowed an attacker to mint an enormous amount of yETH and drain approximately $9 million in assets. Check Point Research (CPR) found that a desynchronization between the pool's main supply counter and its cached virtual balances (packed_vbs[]) enabled the exploit. The attacker used flash loans and repeated deposit/withdraw cycles to pollute cached balances, burned LP tokens to reset supply to zero, then deposited 16 wei to trigger faulty "first deposit" logic and mint inflated tokens, later converting stolen LSD assets to ETH and laundering funds.

🛡️Researchers at Koi Security uncovered a multi-year campaign by an actor dubbed ShadyPanda that abused trusted Chrome and Edge extensions to harvest browsing data, manipulate search results and traffic, and install a backdoor. The group amassed roughly 4.3 million infected browser instances by publishing legitimate-looking add-ons and later pushing malicious updates. Although many extensions have been removed from stores, infected browsers remain at risk because extensions auto-update and marketplaces generally review only at submission.

🔒The University of Phoenix disclosed a data breach tied to a zero-day flaw in Oracle E-Business Suite, saying it detected the incident on November 21 after the extortion group posted the university to its leak site. Phoenix Education Partners filed an SEC 8-K announcing the incident and an ongoing review. The university said attackers accessed names, contact details, dates of birth, Social Security numbers, and bank account and routing numbers for current and former students, employees, faculty and suppliers. Affected individuals will receive mailed notifications with next steps.
