🔒 Check Point Research (CPR) reports that the GoBruteforcer botnet is actively targeting internet‑facing Linux servers, using large‑scale brute‑force attacks against services such as FTP, MySQL, PostgreSQL and phpMyAdmin. The latest Go‑based variant, observed since mid‑2025, introduces heavier obfuscation, stronger persistence and techniques to hide malicious processes. Compromised hosts become scanning and attack nodes, enabling data theft, backdoors, resale of access and further propagation. Analysts also recovered tools used to sweep TRON and Binance Smart Chain assets, underscoring a financial motive behind some campaigns.

📱Acronis says a campaign named Boto Cor-de-Rosa uses WhatsApp to spread the Astaroth banking trojan in Brazil. Attackers distribute ZIP archives via messages; extracting them runs a Visual Basic Script that downloads additional components and an MSI installer. A Python-based worm module harvests WhatsApp contacts and automatically forwards malicious archives to propagate. A background banking module monitors browsing to harvest credentials and the malware logs propagation metrics.

📡 Cisco Talos attributes a long-running cyber-espionage campaign to UAT-7290, a China-nexus actor targeting telecommunications providers since at least 2022. The group prioritizes public-facing edge devices in South Asia and has recently expanded activity into Southeastern Europe, using one-day exploits and SSH brute-force to gain persistent footholds. Its Linux-focused toolkit includes RushDrop, DriveSwitch and the modular backdoor SilentRaid, while Bulbature is used to convert compromised systems into relay nodes that can support other China-linked operators.

📧 Microsoft Threat Intelligence warns of a surge in phishing campaigns that exploit misconfigured mail routing and domain spoofing protections to make malicious messages appear internal to Microsoft 365 tenants. Attackers target users with HR- and IT-themed lures to steal credentials, often pairing the technique with phishing-as-a-service kits like Typhoon2FA. The vector depends on tenants whose MX records are not pointed directly at Office 365, bypassing built-in spoof detection. Organizations should correct MX configuration, enforce DMARC and deploy phishing-resistant MFA for privileged roles.

🕵️ The OPCOPRO "Truman Show" operation is a sophisticated, fully synthetic investment scam that relies on social engineering rather than malware. Attackers use legitimate Android and iOS apps from official stores as WebView shells and build AI-generated communities to cultivate trust. Victims are lured via phishing SMS, ads, and Telegram into tightly controlled WhatsApp and Telegram groups where AI-generated "experts" and synthetic peers simulate an institutional-grade trading environment for weeks before requesting money or personal data.

🔒 Endpoint disruption following serious breaches can take up to two weeks to remediate, and most US and UK organizations report recovery costs in the millions. In a survey of 750 CISOs compiled for an e-book, Absolute Security found 55% had experienced incidents that disabled mobile, remote or hybrid endpoints in the past 12 months. A majority (57%) required 3–6 days for full endpoint remediation, while 19% needed 7–14 days. The report places the average cost per incident at $2.5m, with 98% of respondents spending between $1m and $5m on recovery.

🔍 Cisco Talos discloses UAT-7290, a China‑nexus APT active since at least 2022 that targets telecommunications infrastructure in South Asia and has recently expanded into Southeastern Europe. The actor conducts extensive reconnaissance, uses one‑day exploits and target-specific SSH brute force, and primarily deploys a Linux-centric toolset including RushDrop, DriveSwitch, SilentRaid, and Bulbature. Talos notes UAT-7290 also provisions Operational Relay Box (ORB) nodes that may support other China-nexus operators and provides ClamAV and Snort signatures for detection.

🔍 Zscaler ThreatLabz researchers uncovered three malicious npm packages that delivered a previously undocumented remote access trojan dubbed NodeCordRAT. Uploaded under the username "wenmoonx" and disguised as bitcoin libraries, the packages used a postinstall script to install the final payload. NodeCordRAT uses npm for distribution and Discord as its C2, supporting remote shell execution, screenshots, and file exfiltration including browser credentials and wallet seed phrases.

🔐 A new wave of GoBruteforcer botnet attacks is targeting exposed FTP, MySQL, PostgreSQL and phpMyAdmin services used by cryptocurrency and blockchain projects. Check Point reports the Golang-based botnet brute-forces weak or default credentials—often from servers deployed with AI-generated configuration snippets—and then deploys web shells and downloader stages. The malware scans random public IPv4s, spawning up to 95 threads while skipping private, AWS, and U.S. government ranges. Administrators are advised to remove defaults, audit exposed services, and replace outdated stacks like XAMPP.

🚨A cybercrime gang known as Black Cat has been linked to an SEO poisoning campaign that tricks users with fake download pages for popular programs such as Google Chrome and Notepad++. Visitors are redirected to a GitHub‑mimicking host where a ZIP delivers an installer that creates a desktop shortcut which side‑loads a malicious DLL and deploys a backdoor. The backdoor contacts a hard‑coded C2 and can steal browser data, log keystrokes and capture clipboard contents. Users should avoid clicking unknown search results and download software only from official sources.

📱 Group-IB researchers have documented Android malware enabling unauthorized tap-to-pay transactions by remotely relaying NFC card data. Malicious APK samples—over 54 identified—are distributed in Chinese-language Telegram cybercrime communities and often disguise themselves as legitimate financial apps. Attackers use smishing and vishing to get victims to install a 'reader' app and tap their card; a criminal 'tapper' app and illicit POS terminals then complete the payment. Prominent vendors, including TX-NFC, X-NFC and NFU Pay, sell access via subscriptions and support.

🔒 Palo Alto Networks warns that the Jolly Scorpius group has significantly upgraded its Ransomhouse RaaS with a dual-key encryption trojan called Mario, combining a 32-byte primary key and an eight-byte secondary key that make recovery extremely difficult. Attack automation via MrAgent targets VMware ESXi hypervisors, enabling rapid cluster-wide encryption and firewall neutralization. The campaign primarily targets German companies; recommended mitigations include hardening virtual environments, immutable backups, and strict network segmentation.

🔒 ownCloud has urged users to enable multi-factor authentication (MFA) after reports that threat actors used credentials stolen via infostealer malware to access self-hosted file-sharing instances. The company said the platform was not breached via a zero-day or vulnerability; attackers reused credentials harvested by malware such as RedLine, Lumma, and Vidar. ownCloud recommends enabling MFA, resetting passwords, invalidating sessions, and reviewing access logs to protect data.

🔎 Taiwan’s National Security Bureau (NSB) reports a dramatic rise in Chinese-sourced cyber intrusion attempts against the island’s critical infrastructure in 2025, totaling 960,620,609 recorded attempts. The NSB highlights a tenfold surge against the energy sector and a 54% rise targeting emergency rescue and hospitals, while water resources and finance saw notable declines. Top groups named include BlackTech, Mustang Panda and APT41, which used vulnerability exploitation, DDoS, social engineering and supply-chain methods, often timed to coincide with military or political events.

🔒 Brightspeed is investigating claims that the hacking group Crimson Collective obtained personally identifiable information for over one million customers and disrupted connectivity. The group posted a sample of the data on Telegram in early January and later said it had disconnected many users' home internet, although Brightspeed has not confirmed outages or the breach. The purported dataset includes account records, geolocation details, payment histories and masked card data. The ISP is probing the incident while the authenticity and scope of the claims remain unclear.

🔒 A recent Hudson Rock report reveals a threat actor known as Zestix (aka Sentap) harvested credentials from infostealer logs and accessed cloud file-sharing services such as ShareFile, Nextcloud and OwnCloud because affected organizations did not enforce multi-factor authentication. The actor exfiltrated and auctioned highly sensitive corporate and customer data. The incidents underscore persistent failures in credential hygiene, long-lived stolen credentials and the necessity of MFA and session invalidation.

🛡️ Taiwan's National Security Bureau (NSB) reports a tenfold increase in cyberattacks against the country's energy sector in 2025 compared to 2024. The NSB said incidents tied to China rose 6% overall and affected nine critical sectors, with spikes timed around political events and military activity. Observed attack methods included exploitation of hardware and software vulnerabilities, DDoS, social engineering, and supply-chain compromises targeting industrial control systems and upgrade windows.

🛡️ Researchers report the Kimwolf Android botnet — an Aisuru variant — has grown to nearly two million infected hosts by abusing residential proxy services to reach devices on internal networks. The malware scans for unauthenticated Android Debug Bridge (ADB) endpoints on ports such as 5555 and delivers payloads via telnet/netcat, often targeting low-cost Android TV boxes. Affected devices are used for DDoS, proxy resale, and ad-fraud via third-party SDKs; mitigation includes wiping compromised boxes and preferring Google Play Protect-certified hardware from reputable OEMs.

🚗 Jaguar Land Rover (JLR) says a September 2025 cyberattack forced production shutdowns and resulted in a 43.3% year‑on‑year decline in third‑quarter wholesale volumes. Production only returned to normal by mid‑November and global distribution delays further reduced sales. JLR booked a £196 million hit, confirmed data theft, and said the incident was claimed by the Scattered Lapsus$ Hunters. The U.K. government later approved a £1.5 billion loan guarantee to help stabilise supply chains while tariffs and the planned discontinuation of legacy Jaguar models also weighed on performance.

🔍 OX Security researchers uncovered two malicious Chrome extensions — Chat GPT for Chrome with GPT-5, Claude Sonnet & DeepSeek AI and AI Sidebar with Deepseek, ChatGPT, Claude, and more — installed by over 900,000 users. The add-ons scrape ChatGPT and DeepSeek conversation content and all open tab URLs, then batch-upload harvested data to attacker-controlled servers. Operators used hosted privacy pages and impersonation to obscure activity; users should remove these extensions and audit exposed data immediately.
