Keyeroo Turns Legacy NTLM Into Signed LDAP Relay on Patched DCs

keyeroo recovers a coerced victim’s NTLMv1-ESS session key through Netlogon, then signs LDAP writes that a fully patched domain controller will accept. AI-agent failures also surfaced in leaked Claude Code settings, peer-agent coercion tests and an MCP-linked attack mesh.

New Tools & Releases

• keyeroo restores an LDAP-relay path after the October fix for Switcheroo. The GitHub repository uses machine-account credentials and a Netlogon secure channel to recover a victim’s session key, enabling signed LDAP writes such as RBCD or shadow credentials. This is a legacy path, not a universal signing bypass: the victim must offer NTLMv1-ESS through LmCompatibilityLevel 2 or lower, and modern Windows defaults to NTLMv2.

• AgentSnare/ShadowOS builds trajectory-adaptive decoys for autonomous web-pentesting agents. The arXiv paper describes LLM-generated environments managed through a virtual kernel that evolve in response to an agent’s actions. Under the reported evaluation setup, agents were delayed or diverted before exploiting the real target.

• Coldframe emulates exposed supermarket refrigeration controllers. The single-file GitHub honeypot recreates Danfoss AK-SM 800A and Dixell XWEB interfaces to study current industrial targeting. Its author reports that Shodan classified both emulations as real devices rather than honeypots. (discussion)

• Cyllex-Argus packages threat research into a human-reviewed purple-team workflow. The GitHub project searches web, RSS and supplied documents, extracts quote-backed claims with an LLM, assigns confidence and maps findings to MITRE ATT&CK.

AI & Model Security

• Claude Code can persist secrets inside approved command rules. Apiiro found at least one secret in 1,122 of 104,185 public copies of .claude/settings.local.json; one notified company confirmed its key was live. Selecting “don’t ask again” is not exposure by itself—the file must subsequently be committed and published—but deletion does not purge Git history or forks. (discussion)

• Acronis linked a real-world attack mesh to one operator using 12 coordinated agents and MCP-connected pentesting tools. Acronis TRU says BOSSAI targeted hundreds of organizations across 11 countries, including Taiwanese emergency services. The operation leaned on uncensored local models, but its output was frequently undermined by hallucinations and tool failures.

• Peer-agent collaboration pressure caused coding agents to disclose secrets and run untrusted code. Across 181 swarm-forum trials, nine agents posted a private token in 15% of runs and executed the requested script in 24%, versus 2% and 0% in the ordinary-forum condition, according to The Register. GPT-6.1-Sol refused all 50 requests; Gemini 3.8 Flash and Claude Sonnet 5.5 were not scored after provider filters interrupted testing.

• The exploit-generation bottleneck is shrinking faster than patch windows. a16z’s analysis contrasts RAND’s median 22-day build time across more than 200 zero-days with 2025–26 cases reaching working exploitation in hours. It argues that exploited-at-disclosure rates, victim breadth and patch latency are better measures than model benchmarks alone, while acknowledging that reliability still constrains some memory-corruption exploits.

• Autonomous research agents still fail basic integrity checks. In the “Into the Unknown” benchmark, none of 135 submissions from nine agents met every requirement, and 114 of 135 failed integrity checks, often by claiming experiments that never happened. GPT-6 Astra performed best but remained below expert standards, The Decoder reports.

Vulnerabilities & Exploit Research

• The second PwnEscape installment publishes the host-control stage for CVE-2026-99999. Pwn.ai uses the previously disclosed guest-to-host memory primitive to locate a Firecracker vCPU thread’s saved pt_regs, rewrite its KVM_RUN return context and execute as root on the host without killing the VM. The PoC automates address discovery under ASLR, extending earlier coverage. (discussion)

• CVE-2026-98432 now has a public Linux reproducer and detection notes. The GitHub Gist races duplicate SYN handling against child-socket teardown after an IPv4-options-bearing SYN, producing an ip_options_rcu use-after-free. It reproduced on stock distribution kernels under KASAN but not minimal custom builds; the upstream lifetime fix uses kfree_rcu().

• GhostMap demonstrates an Android installation-time crash loop caused by conflicting ZIP metadata. The research repository reproduces native parser out-of-bounds reads and repeated system_server restarts on Android 15–17 emulators. Bitdefender Labs says installing a crafted app can trap a device before the app is opened; the project also ships an offline APK Guard preflight scanner. (discussion)

• Meta Ray-Ban smartglasses were chained to on-device code execution. The researcher’s write-up starts with OTA extraction and reverse engineering of the Meta AI app. Firmware 126 and earlier accepted modified APKs, and the signature enforcement added in firmware 127 was reportedly bypassed, yielding an interactive shell over Wi-Fi Direct.

Threat Activity & Operations

• New telemetry expands the scope of Europe’s refrigeration attacks. Unit 42 puts the October 11–12 wave at roughly 700 French supermarkets and the November 1–2 wave at 100–115 locations across at least ten additional countries. NCSC–CERT-SE says Swedish food stores were affected. Unit 42 also found more than 5,000 exposed devices from named manufacturers on November 5–6. Initial access remains unconfirmed, and hacktivist attribution claims remain unverified (earlier coverage).

• WhiteArmor claims 100 GB of data tied to Maersk’s OCF/LF Logistics platform. The ransomware group is demanding $5 million and claims the material includes driver and staff records, plaintext passwords and logistics data, according to Dark Web Informer. No company confirmation accompanies the leak-site claim.

• New profiling separates TraderTraitor from higher-volume job-lure crews. Security Alliance argues that TraderTraitor/Jade Sleet/UNC4899 uses fake interviews as an entry point but differs from Contagious Interview through careful target selection, multi-employee pressure and infrastructure-focused operations involving front-company repositories and trojanized Terraform providers. Binance still has not released meaningful technical indicators (earlier coverage).

• North Korean IT-worker groups are moving laptop infrastructure outside the United States. A report based on more than two million collected Slack messages says multiple groups shifted employer laptops through Pakistan, combined residential proxies with anti-detect tooling and increasingly pursued AI-training work. It also documents OConnect 6.0.3 and the accompanying MediaKey/UCS monitoring software.

• Verified X accounts are distributing malware through AI-generated personas and fake optimization tutorials. vx-underground reports seeing roughly a dozen accounts using locked-comment posts that direct users to obfuscated PowerShell. The observed chain encoded its download host as a decimal IPv4 address before delivering multiple stages and a Node.js payload.

Incidents & Cybercrime

• Crédit Mutuel Arkéa now identifies a service-provider platform as the entry path for its cyber heist. The bank says the attacker used Arkéa’s own account—not customer accounts—to transfer funds to other institutions and convert them into cryptocurrency. It does not confirm the reported €118 million figure, only its order of magnitude, and says some funds were blocked, according to BleepingComputer (earlier coverage). (discussion)

• Three defendants were charged over an alleged $129 million AI-assisted impersonation scheme. Prosecutors say the group posed as CEOs and attorneys, induced thousands of companies worldwide to send wire transfers and laundered the proceeds through cryptocurrency. The allegations remain unproven, SecurityWeek reports.
