lnd v0.20.7 and v0.21.6 are Lightning Network Daemon releases announced by Clio Bitcoin Bank. They include a Go-specific mitigation, with the MPTCP flag turned off, for CVE-2026-98432, a use-after-free in the Linux kernel's IPv4 TCP code. The post recommends all users update. It gives no exploit or impact detail.

Wiz Research links October 2026 breaches at AI developer platforms (Fireworks, OpenCode, Warp, Zeabur, Railway and others) to stolen environment-variable credentials for AI access. It details two enterprise AWS Bedrock keys abused after vendor breaches: about 800k and 1.7 million calls, over $100k in list-price usage. It profiles two LLM resale operations, "momo" and "Xingjiabi", that tested the keys.

CVE-2026-98432 is a use-after-free race condition in the Linux kernel IPv4 TCP code (tcp_v4_syn_recv_sock, ireq_opt), affecting kernels back to 4.4 and rated 9.8 by the kernel CVE team (Red Hat rates it 5.9). Anthropic researchers say an unreleased Claude model built an exploit that bypassed KASLR and got remote root on an MPTCP listener in about 53 minutes. The article lists distro patch status and CIQ's nftables mitigation for IP options; disabling MPTCP alone does not help. No in-the-wild exploitation is reported.

Bunny CDN status-page notice, posted 28 October 2026, about unauthorized access at an infrastructure provider that hosted one bunny.net CDN node in Armenia. Traffic was stopped within 20 minutes and the server wiped. No access to the node was found, but cached content, Pull Zone configs and TLS certificates could have been exposed, so all platform certificates were reissued. Customers with their own certificates should rotate them with new private keys.

llm-trails is a research repo that placed 14 LLMs in 13 post-compromise AWS situations, asked only for their next move (single-turn, nothing executed), and coded each answer to CloudTrail events. It includes the llmtrials harness, prompts, codebook, processed dataset (viz_data.json) and an interactive dashboard. Rates are conditioned on the situation shown, and the aim is turning model behavior into detection priorities.

CVE-2026-98432 is a use-after-free in the Linux kernel IPv4 TCP handshake path: a request socket's ireq_opt pointer moves to the child socket as inet_opt and is freed with kfree() while a retransmitted-SYN CPU still reads it under RCU. The fix (commit e3f33b0a1d89) uses kfree_rcu(). The page covers CVSS 9.8 versus vendor scores, Anthropic's MPTCP root-exploit lab demo, per-distribution patch checks, MPTCP listener inventory and detection guidance. The page was truncated before its mitigation section.

SingularityNET exploit (19 September 2026): attackers with signing authority exposed through a cloud infrastructure breach drained 8.72M FET from the Ethereum bridge converter, then minted about 2.3 billion AGIX, NTX, WMTX and CGV. Rekt's transaction-level reconstruction puts gross liquid proceeds near $2.29M, not the $16.77M headline, and traces laundering via Chainflip, Baltex and THORChain. It notes conversionIn() skipped checkLimits() and trusted a single EOA signature.

dontallow is a two-file Swift launchd agent for macOS 15 and later that clicks "Don't Allow" on the "find devices on local networks" prompt. It watches the UserNotificationCenter process through an Accessibility observer, supports pause and allowlist, and can decode the Local Network rule store to show orphaned rows. It explains why Chromium temp-bundle paths make the prompt recur, and gives a PPPC profile route for fleets.

Wiz Research reviews agentic attacks seen in its incident response work and in public reports (ARTEX, Hermes, JPCERT/CC, CrowdStrike, DIVD). It derives fingerprints of AI-agent activity from three intrusions: machine-paced iteration, natural-language reasoning in scripts, self-correcting script versions, checklist enumeration, noisy lateral spraying, probe-before-payload and self-labeled scratch files. It also covers effects on attribution, attack scale and defense.

CVE-2026-98432 is a Linux kernel use-after-free in the IPv4 TCP stack, tracked by Ubuntu (published 15 October 2026, updated 29 October 2026). ireq_opt/inet_opt were freed with plain kfree() while another CPU built a SYNACK under RCU, so ip_options_build() read freed memory; the fix uses kfree_rcu(). Ubuntu rates it High priority, CVSS v3.1 9.8 and v4.0 8.3. The page text does not list per-release package status.

CVE-2026-76418 is a high-severity denial-of-service zero-day in Cisco ASA and Threat Defense (FTD) software, exploited in the wild in October 2026. Unauthenticated attackers send a crafted request to the SSL VPN (webvpn) when secondary authentication is set on a tunnel group, causing a device reload. Cisco offers no workaround besides disabling secondary authentication on tunnel groups. Shadowserver sees over 51,000 exposed ASA SSL VPN devices.
