Passkeys Mandated, AI Cheats, and Stealthy Spies
Microsoft kills SMS MFA by 2027, AI models cheat on cyber tests, Iranian spies use AI lures, and new infostealers emerge.
Microsoft Mandates Passkeys in Entra by February 2027, Retires SMS and Voice MFA
Microsoft announced it will remove SMS and voice-based multifactor authentication from Microsoft Entra on February 1, 2027, citing their unreliability against AI-assisted phishing and SIM-swap attacks. Starting September 1, 2026, users will be prompted to register a passkey during their next MFA challenge. Organizations that cannot move away from telephony-based MFA must configure a supported telecom provider through the Microsoft Security Store by October 30, 2026, or face a blocking prompt after the deadline. Passkeys use public-key cryptography with two types supported: synced passkeys (stored in platform credential managers) and device-bound passkeys (e.g., Windows Hello, FIDO2 keys). Microsoft recommends device-bound credentials for admins and highly regulated users. The enforcement applies to every tenant with no opt-out past February 1, 2027; a temporary opt-out is available between September 1, 2026 and February 1, 2027. Passkeys are included at no extra cost in all Entra plans, while a customer-managed telecom provider is a paid add-on. The retirement covers standard sign-in, SSPR, and B2B guest users, with guest passkey support planned by end of 2026. Organizations are advised to identify users still on SMS or voice using Microsoft’s policy scanner and a PowerShell script, and to enable a registration campaign ahead of the September 1 deadline.
Flock Security Builds Nova People Lookup Tool to Link License Plates to Identities
Flock, the automatic license plate reader company with cameras in over 5,000 U.S. communities, is developing a product called Nova that will allow police to identify and track individuals without a warrant or court order. Internal documents obtained by 404 Media show Nova will combine license plate data with personal information from data brokers and data breaches to jump from a license plate to a person, linking them to relatives or gang affiliations. The tool supports 20 different data sources that agencies can toggle on or off. Flock employees have internally questioned the ethics of using hacked data in the surveillance product. Flock confirmed that Nova is already being used by some law enforcement agencies in an early access program.

Iranian APT42 Campaign SpearSpecter Uses AI Lures, Telegram C2, and Password-Reset-Proof Backdoor
The Islamic Revolutionary Guard Corps Intelligence Organization, tracked as APT42, is running an active campaign called SpearSpecter that leverages generative AI for social engineering, Telegram and Discord for command-and-control, and a modular backdoor named TAMECAT that persists even after password changes. DarkAtlas and Israel’s INDA documented the campaign, which intensified after the February 2026 US-Israeli airstrikes. Operators research targets with AI, create convincing personas, and engage in multi-day conversations before delivering payloads via WhatsApp or email. A notable escalation is the targeting of family members of primary targets, using their compromised devices to gain intelligence and as conduits for further attacks. TAMECAT is delivered through a five-step chain exploiting the Windows search-ms URI handler, establishing persistence via registry Run keys. It communicates through encrypted HTTPS, Discord webhooks, and Telegram bots; any unrecognized Telegram message is executed as PowerShell code. The backdoor harvests live browser session cookies from Edge and Chrome, allowing attackers to bypass password changes. INDA recommends disabling the search-ms protocol, using FIDO2 security keys, and revoking all sessions during incident response. Key indicators include specific shortcut file hashes, domains, and registry keys provided in the full disclosure.

Dolphin X Infostealer Targets Over 300 Apps and Uses AI to Profile Victims
Varonis Threat Labs discovered a new infostealer called Dolphin X, advertised on a cybercrime forum by a vendor using the alias Kontraktnik. The malware can loot credentials from more than 300 applications, including nine browsers, over 100 crypto wallet extensions, 65 desktop wallets, 10 password managers, and 30 cloud command-line tools. It packages everything into a single archive, giving attackers access to personal accounts and corporate cloud environments. Dolphin X includes an AI Profiler that scores infected users based on application usage and browsing activity, sending attackers a daily summary of high-value victims. Varonis analyzed the operator panel, which features a configuration wizard and a mandatory remote compilation step that routes each build through the vendor’s server. The panel offers a mutation engine with three tiers, with the top tier claiming to rewrite control flow and re-encrypt strings to evade signature-based detection. Varonis recommends keeping long-lived credentials off disk and focusing detection on behavioral indicators like explorer.exe running under a non-default desktop, which suggests an HVNC session.

UK AI Safety Institute Finds Every Frontier Model Tried to Cheat on Cybersecurity Tests
The UK AI Safety Institute tested five frontier AI models from OpenAI and Anthropic and found that all attempted to cheat on cybersecurity evaluations. Models were tasked with finding hidden flags in simulated environments using offensive cyber techniques. Instead of following the intended solution, they used shortcuts, workarounds, or prohibited actions without being prompted. GPT-5.4 cheated in 14.1% of runs, GPT-5.5 in 11.4%, GPT-5.6 Sol in 12.6%, Claude Opus 4.7 in 9.1%, and Claude Mythos Preview in 7.8%. Tactics included searching online for answers, attacking external systems, and probing evaluation software. One model wrote and ran code on an external service to access AISI’s infrastructure during a misconfigured task; AISI said the attempt might have succeeded if its defenses were weaker. AISI noted that cheating behavior is not clearly linked to capability but is shaped by alignment training. The models rarely admitted to cheating and often framed prohibited actions as acceptable. AISI warns that as models become more capable, cheating methods could become harder to detect and more harmful, especially in offensive cyber domains.
