🔒 An international law enforcement operation, supported by private researchers, disrupted FrostArmada, an APT28 campaign that hijacked DNS settings on compromised MikroTik and TP-Link routers to intercept Microsoft 365 authentication. The attackers redirected DNS to attacker-controlled VPS nodes acting as AitM proxies and captured logins and OAuth tokens. Microsoft, Lumen Black Lotus Labs, the FBI, the DOJ, and Polish authorities took the malicious infrastructure offline and published indicators and mitigations.

🔒 The UK’s National Cyber Security Centre (NCSC) warns that Russian-linked APT28 has been compromising vulnerable SOHO routers to redirect DNS traffic through attacker-controlled servers and harvest credentials. The actor has modified a list of VPS-hosted DNS servers since 2024 and exploited models including TP-Link (notably the WR841N via CVE-2023-50224) and MikroTik. The campaigns use DHCP DNS tampering and adversary-in-the-middle techniques; the NCSC and Microsoft advise firmware updates, multifactor authentication and network hardening.

🔒 Since at least August 2025, Microsoft Threat Intelligence reports that the Russian military-linked actor Forest Blizzard (and sub-group Storm-2754) has been exploiting insecure SOHO routers to reroute DNS queries to actor-controlled resolvers. The actor appears to use the legitimate dnsmasq service on thousands of devices to capture DNS traffic and, selectively, perform TLS adversary-in-the-middle (AiTM) attacks against Microsoft Outlook on the web and targeted government services. Microsoft identified over 200 affected organizations and more than 5,000 consumer devices and published mitigation, detection, and hunting guidance.

🕵️ GreyNoise analyzed 4 billion malicious sessions over three months and found residential proxies accounted for roughly 39% of traffic yet evaded IP reputation feeds in 78% of cases. Researchers say the short-lived, systematically rotated, or low-activity nature of these addresses prevents timely cataloging by reputation systems. They recommend moving from IP-based blocking to behavior-focused detection, such as spotting sequential probing and tracking device fingerprints that persist through IP rotation.

🔒 Push Security has observed a coordinated wave of Adversary-in-the-Middle (AiTM) phishing pages specifically targeting TikTok for Business accounts. The malicious domains were registered on March 24 in a rapid, nine-second window and are hosted behind Cloudflare using Nicenic International Group as registrar. Victims are redirected through legitimate Google Cloud Storage links, presented with TikTok- or Google-themed content, and ultimately confronted with a reverse-proxy AiTM login flow after completing an initial information form.

🔒 Push Security warns of an adversary-in-the-middle (AitM) phishing campaign that seizes control of TikTok for Business accounts by presenting victims with malicious credential-capture pages after a Cloudflare Turnstile check. Lures include lookalike TikTok for Business and fake Google Careers pages, sometimes offering scheduled calls to gain trust. The attackers host pages on multiple domains and use the Turnstile challenge to evade automated scanners. Separately, WatchGuard reported SVG attachments used to deliver a Go-based malware artifact linked to BianLian-style activity.

🔒 CISA warns of multiple high‑severity vulnerabilities in Automated Logic WebCTRL servers that could allow attackers to read, intercept, or modify BACnet communications. Known affected releases include versions earlier than v8.5, and WebCTRL 7 is end‑of‑life and unsupported. The advisory describes three CVEs — CVE-2026-25086 (port binding impersonation), CVE-2026-32666 (BACnet packet spoofing), and CVE-2026-24060 (cleartext transmission, CVSS 9.1) — and urges operators to upgrade to supported releases with BACnet/SC, implement TLS/mutual authentication where available, and apply network segmentation, access controls, and vendor secure configuration best practices to reduce exposure.

🔐 Modern phishing now uses adversary-in-the-middle proxies that capture entire authentication flows, including MFA prompts and session cookies. Employees can complete legitimate logins and still be compromised because attackers replay session tokens from a different machine. Organizations must move beyond traditional MFA and outdated awareness training and instead deploy phishing-resistant authentication, bind sessions to managed devices, and monitor post-authentication behavior.

⚠️AirSnitch exploits cross-layer identity desynchronization between Layers 1 and 2 to mount full, bidirectional machine-in-the-middle attacks. An attacker on the same SSID, a different SSID, or another segment tied to the same AP can intercept and modify link-layer traffic. The technique affects home, office, and enterprise Wi‑Fi and enables DNS poisoning, credential theft, and exploitation of unpatched flaws.

🛡️ A Europol-led coalition of law enforcement and private cybersecurity firms dismantled Tycoon 2FA, a subscription-based phishing-as-a-service toolkit that enabled adversary-in-the-middle credential and session harvesting at scale. The platform provided a web console for crafting campaigns, harvesting passwords, MFA codes and session cookies, and forwarding stolen data to Telegram for near-real-time monitoring. Authorities seized 330 domains and disrupted infrastructure that generated tens of millions of phishing emails per month, affecting organizations worldwide.

🔎 Tycoon2FA emerged in August 2023 as a phishing-as-a-service platform that provided adversary-in-the-middle (AiTM) capabilities to relay authentication flows and capture session cookies. Its web-based admin panel centralized templates, redirects, hosting, CAPTCHA, and exfiltration controls while exposing real-time metrics. Fast-moving short-lived domains, Cloudflare hosting, and heavy obfuscation let low-skill operators run scalable campaigns against MFA-protected accounts worldwide.

🛡️ Microsoft and Europol, supported by industry partners, seized infrastructure linked to the phishing-as-a-service operator Tycoon2FA, removing over 300 domains used in large-scale MFA-bypass campaigns. The PhaaS offering used adversary-in-the-middle techniques to intercept live authentication sessions and capture credentials, one‑time passcodes and session cookies in real time. Investigators say Tycoon2FA had roughly 2,000 users and leveraged more than 24,000 domains since launching in August 2023. Security firms recommend adopting phishing‑resistant authentication, strict conditional access and advanced email protections.

🔒 Cybersecurity researchers disclosed Starkiller, a commercial phishing suite marketed by a group calling itself Jinkusu that proxies legitimate login pages to bypass multi-factor authentication. The platform launches a headless Chrome instance inside a Docker container and acts as an AitM reverse proxy, relaying keystrokes, form submissions and session tokens. Abnormal warns the toolkit centralizes deployment, URL masking and session monitoring to give low-skill criminals effective MFA-bypass capabilities at scale.

🛡️ Cisco Talos researchers describe DKnife as an ELF-based Linux toolkit used since 2019 to hijack router traffic and perform adversary-in-the-middle operations. The framework has seven modules — including yitiji.bin to create a bridged TAP interface and mmdown.bin to drop malicious APKs — enabling DPI, credential harvesting, and delivery of backdoors such as ShadowPad and DarkNimbus. Talos attributes the activity to a China-nexus actor and noted C2 servers remained active as of January 2026.

🔍 Cisco Talos researchers uncovered DKnife, a Linux-based gateway-monitoring and adversary-in-the-middle framework used since at least 2019 and active through January 2026. The toolkit targets routers and edge devices running CentOS/Red Hat Enterprise Linux, using seven ELF components to perform DPI, traffic interception, DNS hijacking and in-line substitution of Android and Windows downloads. Talos attributes the framework with high confidence to Chinese-nexus actors and notes overlaps with campaigns delivering WizardNet, DarkNimbus and ShadowPad.

🔒 Cisco Talos researchers disclosed DKnife, a modular Linux-based adversary-in-the-middle (AitM) framework used by China-linked actors since at least 2019. The toolkit deploys seven router-focused implants to perform deep packet inspection, TLS termination, DNS and update hijacking, credential harvesting, and malware delivery via intercepted APKs and binary replacement. Operators used DKnife to push ShadowPad and DarkNimbus variants and to target Chinese-language services and app updates through compromised routers and edge devices.

🔍 Cisco Talos disclosed DKnife, a modular Linux-based gateway monitoring and adversary-in-the-middle (AitM) framework that inspects, manipulates, and redirects network traffic on edge devices and routers. It comprises seven ELF components that hijack DNS, Android app updates, and Windows binary downloads to deliver ShadowPad, DarkNimbus, and other backdoors while harvesting credentials and disrupting security-product traffic. Artifacts and Simplified Chinese strings strongly indicate China-nexus operators; Talos observed active C2 infrastructure as of January 2026.

🔒 Microsoft warns of a multi-stage adversary-in-the-middle (AitM) phishing and BEC campaign targeting the energy sector. The attackers abused SharePoint file-sharing and legitimate trusted addresses (a living-off-trusted-sites, LOTS, technique) to deliver credential-harvesting links, then used stolen session cookies and inbox rules to persist and hide activity. Microsoft says simple password resets are insufficient; organizations must revoke sessions, remove malicious rules, and enforce phishing-resistant controls.

🔒 Microsoft Defender researchers uncovered a multi‑stage AiTM phishing and BEC campaign that abused SharePoint file‑sharing to deliver credential‑harvesting traps and maintain persistence by creating malicious inbox rules. Attackers used trusted vendor‑style lures and legitimate SharePoint redirects to capture session cookies or credentials, then expanded the campaign across energy sector organizations by sending more than 600 phishing messages from compromised accounts. Defender XDR and Office 365 detections exposed session cookie theft, replay attempts, and malicious inbox rules — remediation requires revoking session cookies, deleting attacker‑created inbox rules, and restoring MFA controls in addition to password resets.

🛡️ Spanish law enforcement arrested 34 individuals in a coordinated operation targeting a criminal network tied to the Black Axe syndicate, with assistance from the Bavarian State Criminal Police Office and Europol. Searches in Seville, Madrid, Malaga, and Barcelona yielded €66,400 in cash, electronic devices, vehicles, and frozen bank accounts totaling €119,350. Authorities say the group specialized in Man-in-the-Middle (MITM) frauds, notably Business Email Compromise, and caused more than $6 million in losses over 15 years, $3.5 million of which relate to this case. Four principal suspects are in pretrial detention and face charges including aggravated continuous fraud, money laundering, and document forgery.
