All news with #spear phishing tag

📚 Kaspersky reported a targeted phishing campaign linked to Operation ForumTroll observed in October 2025 that impersonated the Russian eLibrary service. Attackers used a long-aged bogus domain to send personalized emails with one-time links to ZIP archives named for each victim, which contained a .LNK that runs a PowerShell downloader. The chain fetches a staged payload that loads a final DLL, persists via COM hijacking, deploys the Tuoni C2 framework for remote access, and shows a decoy PDF to victims.

📧 Kaspersky researchers have uncovered a targeted campaign by the ForumTroll APT that lures political scientists with personalized plagiarism-check links impersonating the eLibrary service. The downloaded archive contained a malicious .lnk and a .Thumbs directory with images used to evade security; filenames included each victim’s full name. When executed on Windows the .lnk ran a PowerShell chain that installed the commercial red-team framework Tuoni, used COM hijacking for persistence, and displayed a decoy PDF named for the target. Kaspersky reports detections and recommends endpoint and mail-gateway protections to stop similar email-delivered threats.

🔐 Unit 42 details activity by Hamas-affiliated Ashen Lepus using a new modular .NET suite named AshTag, alongside custom loaders and revised C2 techniques to evade detection. The actors targeted Arabic-speaking government and diplomatic entities across the Middle East, delivering malware via RAR archives, DLL sideloading, and payloads hidden in benign HTML. Operators improved encryption and domain masquerading and performed hands-on exfiltration using Rclone. Organizations should monitor the provided IOCs and strengthen EDR and egress controls.

🔒 The Iranian-linked group MuddyWater has been observed deploying a new UDP-based backdoor called UDPGangster, using UDP channels for command-and-control, data exfiltration, and remote command execution. Fortinet FortiGuard Labs says the campaign targeted users in Turkey, Israel, and Azerbaijan via spear-phishing messages that deliver macro-enabled Word documents (e.g., "seminer.doc" inside "seminer.zip") and display a Hebrew-language decoy image. The embedded VBA macro decodes Base64 content into C:\Users\Public\ui.txt and launches it via CreateProcessA; the payload establishes registry persistence and runs multiple anti-analysis checks before communicating over UDP to 157.20.182[.]75:1269 to exfiltrate data, run commands with "cmd.exe", transfer files, and deploy additional payloads.

🔒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.

📧 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.

🔒 Professionals routinely share work-related details on platforms such as LinkedIn, GitHub and consumer networks like Instagram and X, creating a public intelligence trove that attackers readily exploit. Job titles, project names, vendor relationships, commit metadata and travel plans are commonly weaponised into spearphishing, BEC and deepfake-enabled schemes. Organisations should emphasise security awareness, implement clear social media policies, enforce MFA and password managers, actively monitor public accounts and run red-team exercises to validate controls.

🛡️ Kaspersky researchers report that the Tomiris threat actor has increasingly used legitimate public services such as Telegram and Discord as command-and-control channels to blend malicious traffic with benign activity. The campaign relies on tailored spear-phishing with password-protected RAR attachments, multi-language implants, and open-source C2 frameworks like Havoc and AdaptixC2. Targeting focuses on Russian-speaking governmental and diplomatic entities across Central Asia and Russia, enabling long-term persistence and covert intelligence collection.

🐺 Group-IB and Ukuk report that the actor known as Bloody Wolf has conducted spear-phishing campaigns since June 2025 targeting Kyrgyzstan and, by October 2025, expanded into Uzbekistan to deliver NetSupport RAT. Attackers impersonate government ministries using malicious PDFs that host Java Archive (JAR) loaders built for Java 8, instructing victims to install Java so the loader can execute. The loader fetches the NetSupport payload and establishes persistence via scheduled tasks, registry entries, and a startup batch script in %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup.

🔎 Researchers at Group-IB and UKUK have identified a widening campaign by the Bloody Wolf APT that uses streamlined Java-based loaders to deliver NetSupport remote administration software to government targets. The operation, active since late 2023 and observed in Kyrgyzstan from at least June 2025 before spreading to Uzbekistan in early October, relies on convincing PDF lures, spoofed domains and geofenced infrastructure. Simple Java 8 loaders fetch NetSupport over HTTP, add persistence via autorun entries and scheduled tasks, display fake error messages, and include a launch-limit counter to limit execution and avoid detection. The group has shifted from using STRRAT to deploying an older 2013 build of NetSupport Manager and uses a custom JAR generator to mass-produce variants.

🔒 Social media influencers are increasingly attractive targets for cybercriminals who hijack trusted accounts to distribute scams, malware and fraudulent offers. Attackers use spearphishing, credential stuffing, brute-force attacks and SIM swapping, and AI is making those lures more convincing. Compromised accounts may be sold or used to push crypto and investment scams, exfiltrate follower data or extort victims. Practical defences include long, unique passwords, app-based 2FA, phishing awareness, device separation and up-to-date security software.

🛡️ The Israel National Digital Agency (INDA) has attributed a new espionage campaign codenamed SpearSpecter to Iranian state‑aligned APT42, active since September 2025 against senior defense and government officials and their family members. Operators employ tailored social engineering—invites to conferences and impersonated WhatsApp contacts—to deliver a WebDAV‑served .LNK via the search‑ms: handler that retrieves a batch script and stages the TAMECAT PowerShell backdoor. TAMECAT uses HTTPS, Discord, and Telegram for command-and-control, supports modular data‑theft capabilities (browser and Outlook exfiltration, screenshots), and relies on Cloudflare Workers, LOLBins, in‑memory execution, and obfuscation to maintain persistent, stealthy access.

📧 Volexity has linked a series of spear-phishing campaigns from June to August 2025 to a China-aligned actor tracked as UTA0388. The group used tailored, rapport-building messages impersonating senior researchers and delivered archive files that contained a benign-looking executable alongside a hidden malicious DLL loaded via search order hijacking. The distributed malware family, labeled GOVERSHELL, evolved through five variants capable of remote command execution, data collection and persistence, shifting communications from simple shells to encrypted WebSocket and HTTPS channels. Linguistic oddities, mixed-language messages and bizarre file inclusions led researchers to conclude LLMs likely assisted in crafting emails and possibly code.

🛡️ A Russia-aligned cluster tracked as InedibleOchotense impersonated Slovak vendor ESET in May 2025, sending spear-phishing emails and Signal messages to multiple Ukrainian organizations. Recipients were directed to domains such as esetsmart[.]com hosting a trojanized installer that deployed the legitimate ESET AV Remover alongside a C# backdoor dubbed Kalambur (aka SUMBUR). Kalambur leverages the Tor network for command-and-control and can install OpenSSH and enable RDP on port 3389 to facilitate remote access. ESET links the campaign to Sandworm sub-clusters and notes overlaps with activity reported by CERT-UA and EclecticIQ.

🛡️ Proofpoint has identified a previously unknown cluster it calls UNK_SmudgedSerpent that targeted academics and foreign policy experts between June and August 2025. Attackers initiated benign, topical conversations and used think‑tank impersonation alongside an OnlyOffice‑styled link that led to health-themed domains harvesting credentials and delivering a ZIP with an MSI. The installer deployed remote monitoring and management tooling — notably PDQConnect and later ISL Online — and although email activity paused in early August, related infrastructure later surfaced hosting TA455-linked malware, leaving attribution unresolved.

🔍 Proofpoint attributes a previously unseen cluster, UNK_SmudgedSerpent, to targeted attacks on U.S. academics and foreign‑policy experts between June and August 2025. The adversary used tailored political lures and credential‑harvesting landing pages, at times distributing an MSI that deployed legitimate RMM software such as PDQ Connect. Tactics resemble Iranian-linked groups and included impersonation of think‑tank figures to increase credibility.

🚚 Proofpoint warns of a spear‑phishing campaign targeting North American freight firms that installs remote monitoring and access tools to enable cargo theft. Actors compromise broker load boards, insert themselves into carrier email threads, or pose as brokers to deliver signed installers that harvest credentials and establish persistent access. The attackers have deployed a range of RMM/RAS solutions (for example ScreenConnect, SimpleHelp, PDQ Connect, Fleetdeck, N‑able, and LogMeIn Resolve) and use them to bid on or reroute high‑value loads; Proofpoint urges blocking unauthorized RMMs, enforcing endpoint/network detection and MFA, disallowing external executables, and expanding phishing awareness training.

🛡️Arctic Wolf reports that Chinese government-linked actors, tracked as UNC6384 and linked to the longer-running Mustang Panda cluster, conducted spear-phishing campaigns in September and October targeting diplomats in Hungary, Belgium, Serbia, Italy and the Netherlands by abusing a long-known Windows .LNK shortcut parsing flaw. The vulnerability allows command-line instructions to be concealed in .LNK whitespace so attackers can display decoy PDFs—such as an agenda for a European Commission meeting—while executing payloads that deploy the PlugX remote-access Trojan. Trend Micro and ZDI previously documented the issue (i.e., ZDI-CAN-25373, later CVE-2025-9491), but Microsoft has so far declined to fully patch it; Arctic Wolf advises blocking or disabling .LNK execution, monitoring for related binaries like cnmpaui.exe, and blocking C2 domains as interim mitigations.

🔒 A China-affiliated group tracked as UNC6384 exploited an unpatched Windows shortcut flaw (ZDI-CAN-25373, CVE-2025-9491) to target diplomatic and government entities in Europe between September and October 2025. According to Arctic Wolf, the campaign used spear-phishing links to deliver malicious LNK files that launch a PowerShell stager, sideload a CanonStager DLL, and deploy the PlugX remote access trojan. Microsoft says Defender detections and Smart App Control can help block this activity.

🔎 Researchers at Arctic Wolf Labs uncovered a September–October 2025 cyber-espionage campaign that used a Windows shortcut vulnerability to target Belgian and Hungarian diplomatic entities. The operation, attributed to UNC6384 and likely tied to Mustang Panda (TEMP.Hex), combined spear phishing with malicious .LNK files exploiting ZDI-CAN-25373 and deployed a multi-stage chain ending in the PlugX RAT. Attackers used DLL side-loading, signed Canon utilities and obfuscated PowerShell to extract and execute an encrypted payload while displaying decoy diplomatic PDFs.
