🔍 ESET Research summarizes notable APT operations observed from April through September 2025, highlighting activity by China-, Iran-, North Korea-, and Russia-aligned groups. The report documents increased use of adversary-in-the-middle techniques, targeted spearphishing (including emails sent from compromised internal inboxes), and expanded campaigns against government, energy, healthcare, and maritime sectors. Notable tools and threats include BLOODALCHEMY, SoftEther VPN infrastructure, a WinRAR zero-day exploit, and a newly identified Android spyware family named Wibag. Findings are based on ESET telemetry and verified analysis.

🔒 Security researchers at Gen Digital disclosed a targeted Kimsuky campaign that delivered a previously undocumented backdoor called HttpTroy, hidden inside a ZIP attachment masquerading as a VPN invoice. The multi-stage chain used a Golang dropper, a loader dubbed MemLoad and a DLL backdoor executed via a scheduled task named "AhnlabUpdate" to achieve persistence. HttpTroy provides extensive remote-control capabilities and communicates with a C2 server over HTTP, while employing layered obfuscation to hinder analysis and detection.

🔍 Sekoia.io researchers uncovered a cyber-espionage campaign, beginning June 2025, that targets Indian government Linux systems using a new Golang RAT named DeskRAT. The operation primarily abused the Indian government‑endorsed BOSS Linux distribution via phishing ZIPs that executed Bash downloaders and displayed decoy PDFs. Attackers used dedicated staging servers and a new operator dashboard to manage victims and exfiltrate files.

🧠 Kaspersky researchers have identified a sophisticated cyber-espionage campaign dubbed PassiveNeuron that has targeted government, financial, and industrial organizations across Asia, Africa, and Latin America since late 2024. The operation uses bespoke implants—Neursite (a C++ modular backdoor) and NeuralExecutor (a .NET loader)—alongside Cobalt Strike, leveraging compromised internal servers as intermediate C2s and a plugin architecture to maintain persistence and adapt tooling. Victims include internet-exposed servers; attackers have used SQL-based remote command execution, attempted ASPX web shells, deployed DLL loaders into the System32 directory, and in 2025 adopted a GitHub-based dead-drop resolver to retrieve C2 addresses.

🔎 SEQRITE's APT-Team describes how they used VirusTotal to pivot from isolated clues to comprehensive campaign mapping, tracking UNG0002, Silent Lynx, and DRAGONCLONE between May 2024 and May 2025. Their work combined malware configuration extraction, LNK metadata, code-sign certificate pivots, YARA and Sigma rules, and Livehunt queries to surface related samples and previously unreported implants. The post highlights practical hunting queries and pivots — public key and LNK-ID searches, submitter geofilters, and malware_config values — that enabled attribution and expanded detection across multiple Asian geographies.

🔐 British officials briefly considered physically destroying a government data hub after uncovering a decade-long intrusion attributed to China-aligned actors. The breach reportedly exposed official-sensitive and secret material on government servers, though no top secret data was taken. Rather than demolish the facility, the government implemented alternative protections and commissioned a classified review. Cybersecurity experts say the episode underscores the critical need to secure supply chains and hunt long-term APT presence.

🔐 Google Threat Intelligence has linked a campaign to UNC5342, a cluster tied to North Korea, that now uses EtherHiding to distribute malware via smart contracts on public blockchains such as BNB Smart Chain and Ethereum. The attackers lure developers through LinkedIn recruitment ruses, move conversations to Telegram or Discord, and deliver npm-package downloaders that chain into BeaverTail, JADESNOW, and the Python backdoor InvisibleFerret. By embedding payloads in on-chain contracts, the group turns blockchains into tamper-resistant dead-drops that are hard to takedown and easy to update, enabling sustained cryptocurrency theft and long-term espionage.

🔒 Researchers at ReliaQuest found China-linked APT Flax Typhoon modified an ArcGIS Server Object Extension (SOE) into a persistent web shell that executed base64-encoded commands via standard ArcGIS operations. The actor used a hardcoded key, staged tools in a hidden C:\Windows\System32\Bridge directory, and renamed a SoftEther VPN binary to bridge.exe to maintain covert connectivity. The malicious SOE was replicated into backups and golden images, allowing access to survive system recovery while attackers performed discovery, credential harvesting, lateral movement, and covert VPN-based persistence.

🔒 DarkAtlas researchers warn that APT groups are leveraging legitimate RMM platforms to gain initial access, increasingly favoring ScreenConnect as it evades basic detection. Attackers abuse features like unattended access, VPN, REST API and file transfer, deploy in-memory installers that leave little disk artefacts, and register persistent services such as ScreenConnect.WindowsClient.exe. Defenders should monitor invite links, config files, in-memory activity and specific event IDs for effective DFIR.

🔎 Researchers at Palo Alto Networks have attributed two years of coordinated espionage to a previously unreported Chinese-aligned threat actor dubbed Phantom Taurus. The group targets government and telecommunications organizations across Africa, the Middle East, and Asia, focusing on foreign ministries, embassies, geopolitical events and military operations to maintain persistent covert access. Its toolkit includes a new IIS web-server backdoor suite called NET-STAR, DNS- and remote-access tools, in-memory implants and a wide mix of dual-use utilities. Operators have shifted from Exchange mailbox harvesting via ProxyLogon and ProxyShell exploits to targeted SQL database searches and WMI-driven data extraction.

🔍 Palo Alto Networks Unit 42 has attributed a two-and-a-half-year campaign of espionage to a previously undocumented China-aligned actor dubbed Phantom Taurus, which has targeted government and telecommunications organizations across Africa, the Middle East, and Asia. The group uses a bespoke .NET malware suite called NET-STAR to compromise Internet Information Services (IIS) web servers and maintain stealthy access. Observed techniques include exploitation of on-premises IIS and Microsoft Exchange flaws, in-memory payload execution, timestomping and AMSI/ETW bypasses, enabling persistent data collection tied to geopolitical events.

🔒 PRODAFT links a recruitment-themed espionage campaign to an Iran-affiliated cluster tracked as Subtle Snail and attributed to UNC1549 (aka TA455), reporting infiltration of 34 devices across 11 telecommunications organizations in Canada, France, the UAE, the UK and the US. Operators posed as HR recruiters on LinkedIn and delivered a ZIP-based dropper that uses DLL side-loading to install the modular backdoor MINIBIKE, which harvests credentials, browser data, screenshots, keystrokes and system details. MINIBIKE communicates with C2 infrastructure proxied through Azure services, employs anti-analysis measures and achieves persistence via registry modifications to enable long-term access and data exfiltration.

🛡️ Bitdefender attributed a campaign against a Philippines-based military contractor to a China-linked APT that deployed a previously undocumented fileless framework named EggStreme. The multi-stage operation begins with EggStremeFuel (mscorsvc.dll), which profiles systems, opens a C2 channel, stages loaders, and triggers in-memory execution of the core backdoor via DLL sideloading. EggStremeAgent functions as a central backdoor, injecting a session-specific keylogger (EggStremeKeylogger), communicating over gRPC, and exposing a 58-command toolkit for discovery, lateral movement, privilege escalation and data theft. An auxiliary implant, EggStremeWizard (xwizards.dll), provides reverse-shell access and resilient C2 options; Bitdefender warned that fileless execution and heavy DLL sideloading make detection and forensics difficult.

🛡️ The U.S. Department of State is offering up to $10 million for information on three Russian FSB officers accused of carrying out cyberattacks against U.S. critical infrastructure. The named individuals — Marat Valeryevich Tyukov, Mikhail Mikhailovich Gavrilov, and Pavel Aleksandrovich Akulov — are tied to the FSB's Center 16, tracked under aliases such as Berserk Bear and Dragonfly. Charged in March 2022, the officers are alleged to have run intrusions from 2012–2017 targeting government agencies and energy firms, and recent activity shows exploitation of CVE-2018-0171 in end-of-life Cisco devices. The State Department directs tips to its Rewards for Justice Tor channel; eligible informants could receive rewards and relocation assistance.

🔍 Cisco Talos describes UAT-7237, a Chinese‑speaking APT active since 2022 that compromised a Taiwanese web hosting provider to establish long‑term persistence. The actor relies largely on open‑source tooling, customized utilities and a tailored shellcode loader tracked as SoundBill, which can decode and execute Cobalt Strike beacons. UAT-7237 favors SoftEther VPN and RDP for access rather than mass web‑shell deployment. Talos provides IOCs and mitigation guidance for detection and blocking.
