Polymarket is returning $3.9 million to traders after an October 29, 2026 supply chain attack in which malicious JavaScript was served from a DebugBear address its site loaded. DebugBear says its DNS records were compromised through its domain registrar, and attackers appear to have targeted one customer. The script abused open trading sessions to sell positions or move assets; 726 wallets were affected, and about 5,500 wallets received $1.19 million for halt and forced-sale losses.

The Block reports that North Korean hackers (TraderTraitor) laundered about $242 million of funds stolen from Binance through Tron in two days, according to analyst SomaXBT. Relay, THORChain, Chainflip and Symbiosis moved about $140 million off Tron. Elliptic counts $2.85 billion frozen or seized, 44% of $6.43 billion stolen, and $3.25 billion in assets no issuer can freeze. The FBI urged THORChain and others to block listed addresses.

Polymarket halted trading on 29 October after users reported unauthorized withdrawals traced to malicious JavaScript served from DebugBear's real user monitoring snippet. Hudson Rock's sample abused the authenticated session to sell positions or send tokens to a hard-coded address, without exfiltrating credentials. Loss estimates range from $2.19 million to $2.71 million (GoPlus), and Polymarket pledged reimbursement.

WM-Basin is a Meta method for detecting student LLMs distilled from watermarked teacher models, described in "Watermark Basins: Black-Box Detection of Distilled LLMs" (arXiv:2610.37266, 27 October 2026). It feeds a suspect model's API text into a clean probe model and checks gradient alignment with a key-specific watermark basin. It reached 79% true-positive rate at 0.1% false-positive rate across 1,200 students, versus 29% for the prior token-level detector. Clean-data fine-tuning and paraphrasing weaken it.

The top model reached 28,412 downloads and scanned clean, and a second wave returned within days of takedown. The article also covers a fake Solana starter kit on GitHub that installs NetSupport Manager via a PowerShell one-liner aimed at AI coding agents.

Roughly 2,000 also had emails, phone and passport numbers exposed. ANA, Asiana Airlines and Korean Air are also reported as affected. Amadeus had announced a booking display vulnerability on 1 October 2026 and has not given the full scope.

Polymarket suspended trading for about an hour on 29 October 2026 after attacker-controlled JavaScript was served through DebugBear's Real User Monitoring script (cdn.debugbear[.]com/C7xcKKrjUnXK.js). The script hijacked logged-in trading sessions, sold positions and moved assets to an attacker wallet, with about $2.5M traced. The article gives the wallet address, the data.debugbear.com C2 endpoint and Hudson Rock's findings.
Rekt News analysis of the 30 September to 1 October 2026 theft of 3.865 million USDT from the NEAR Intents HOT Bridge treasury on BNB Chain, paid out in five signed withdrawals after a 10 USDT deposit. It uses Bitquery's trace of laundering via Chainflip, THORChain, KuCoin and Hyperliquid, and a NEAR regression test showing an oversized refund log made mt_resolve_deposit fail. NEAR said the funds were returned but published no report.
Polymarket put its exchange in cancel-only mode and paused relayer actions on 29 October 2026 after users reported funds withdrawn without permission. Hudson Rock says a DebugBear-hosted script holds wallet-draining code that sells a logged-in user's positions and hard-codes the suspected attacker's wallet (about $2.65 million in POL, per Arkham) as fallback recipient. Polymarket blames a compromised third-party provider and promises to make users whole. Root cause and victim count are unconfirmed.

Hygentra's six-month study (February to August 2026) audited four AI trading agents, each with its own strategy and preset risk rules, through a 29% Bitcoin decline and recovery. 97.5% of losses by value stayed within limits, 23 of 24 runs respected the five-open-trade cap, and no agent raised risk after a loss. Trade records and testing tools were published; 18% of positions were real Hyperliquid orders, the rest simulated with a 0.09% round-trip fee.

Glamsterdam deposit bug: Ethereum developers merged a consensus-spec fix on 26 October 2026 for a flaw in the upcoming upgrade. An operator could register as a builder under a public key, then a staking service's validator deposit under the same key would be credited to the builder, so no validator is created and funds are unrecoverable. Pending deposits are now sorted by withdrawal credentials. No losses were reported, and client teams still have to implement the change.

Projects must be at least one year old, OSI-licensed, actively maintained and have roughly three or more contributors. Moderator Wolvereness said there is no objective way to enforce the AI rule. Users questioned the Linux kernel's eligibility and started r/trueopensource.
RoSA is a finetuning framework from Qiuyu Kong and three co-authors for long-text image-text retrieval. It targets "saliency collapse", where models over-rely on text tied to prominent visual features and miss contextual information. RoSA splits pairs into salient and contextual views using object-level saliency estimation and LLM text decomposition, then trains on both with plug-and-play auxiliary alignment objectives. Code and checkpoints are public.

Max Woolf's post (minimaxir.com, October 2026) gives a dated timeline of OpenAI and Anthropic price cuts from June to September 2026, including GPT-5.6 Luna down 80%, Opus 5.5 at $4 / $20 / $0.20 and GPT-6.1 Sol at $2 / $10 / $0.10. It argues the cuts come from commodity models, open-weight competition (DeepSeek V4.1 Flash, Kimi K3.1 Pro, 29 OpenRouter providers) and possibly IPO positioning. It notes cache reads make up 96-99% of coding-agent token spend.

LiteLLM version 1.107.0 was published with malware to PyPI and Docker Hub on October 21, for about three hours and roughly 49,000 downloads. Attackers used GitHub CLI OAuth tokens, likely leaked through Claude Code into LiteLLM logs, to disable branch protections, redirect the releaser to a lookalike repository and sign poisoned artifacts. The payload is an infostealer and RAT; Wiz saw Amazon Bedrock abuse. The last clean version is 1.106.2.

The author says the many GitHub "PoC" repositories fail against a vanilla PHP instance in Docker. They claim LLM agents produced them by depending on a local-file-inclusion flaw or by modifying the server to be vulnerable. The author also argues that LLM defaults make many people's judgements identical.
