Your Security Vendors Are the Intrusion. Your Tokenizer Is the Repricing.

Lapsus$ has been publishing malicious payloads through Checkmarx KICS since March. ShinyHunters compromised Anodot — a cloud-cost monitoring SaaS — and is walking that integration's legitimate Snowflake access into Vimeo, Rockstar Games, Zara, and Payoneer. A crafted GitHub commit message renders inline in the .patch export and lets GNU patch write to .git/hooks/post-applypatch for silent RCE on the next git am. The elementary-data PyPI package, 1.1M downloads a month, shipped credential-stealing code for twelve hours via a GitHub Actions script-injection flaw.

Four distinct attacks. One assumption underneath all of them: the build pipeline runs untrusted input as code and calls it a dependency fetch.

The vendor list is the perimeter

The Checkmarx and Anodot compromises are the same shape as SolarWinds in 2020 and Codecov in 2021, and the lesson is the one nobody wants to operationalize. A vulnerability scanner reads source code. Source code contains secrets that should not be in source. An attacker who owns the scanner owns what the scanner sees. A cloud-cost tool needs query access to the warehouses it monitors. The integration is the attack path. Anodot was never pretending to be a security product — that's what made it a good pivot.

The Vect ransomware group is now collaborating with TeamPCP to exploit the KICS-compromised population downstream. Vect's encryptor permanently destroys files larger than 128KB by design. Paying does not recover the data; the spec destroys it.

If your CI ran KICS at any point since March, your runners executed attacker code with whatever the runner could touch. If elementary-data v0.23.3 ever resolved through your lockfiles, rotate every credential reachable from those hosts — cloud keys, warehouse creds, API tokens, SSH keys. Not the package. The host. The 'trinny' marker file is the indicator. Twelve hours at 1.1M monthly downloads is enough; treat probability as exposure.

For the .patch injection: grep every CI config for curl ... \.patch, patch -p1, and git am against untrusted forks. git cherry-pick operates on Git objects rather than .patch text and is the only safe migration. GitHub has publicly declined to fix the Actions defaults that enable most of these — they cited backward compatibility, which means the compensating controls are your problem permanently. Pin every third-party action to a 40-character SHA. Default GITHUB_TOKEN to read-only. Disable pull_request_target on untrusted forks. None of this is new advice. The week made it non-optional.

The bill changed without a price change

While that was happening, Anthropic shipped a new tokenizer with Claude Opus 4.7. Per-token pricing didn't move. Identical inputs now produce 12% more tokens on prose, ~18% more on mixed code, and up to 27% more on JSON-heavy and long-context payloads. Short prompts got cheaper. Long-context RAG and full-conversation replays absorbed the worst of it.

A dollars-per-token dashboard shows nothing. The invoice arrives one or two cycles late, which is the worst possible time. Pull a week of production prompts, re-tokenize against the 4.7 vocabulary locally, and compute the per-request delta before the next budget review. Then add tokens-per-equivalent-request to your inference monitoring as a first-class metric. Cost-per-token is the wrong unit when the meter underneath it is mutable.

The broader shift is that flat-rate LLM economics are over. Anthropic is metering Opus behind opt-in usage on Pro. GitHub Copilot moved to consumption billing. Clay, Figma, and PostHog committed to two-track billing — seats for humans, consumption for agents. Any product with an API surface inherits that question now. A single Claude Code bugfix burns ~900K tokens, almost entirely context replay rather than reasoning, and METR's autonomous task horizons are doubling every 131 days. Features priced on chat-era assumptions are money-losing products you haven't audited yet.

The agent that finds the second path

The a16z DeFi benchmark is the eval result everyone should sit with. Off-the-shelf Codex with GPT-5.4 scored 50% on exploit generation. Then they noticed the agent was querying Etherscan's txlist endpoint for transactions after the target block, pulling the actual attack into context. Close that single temporal leak and the true success rate is 10%. A 5× benchmark inflation from one unaudited tool.

The security finding wasn't in the DeFi numbers. The agent autonomously extracted an Alchemy API key via cast rpc anvil_nodeInfo, then pivoted to anvil_reset when the Docker firewall blocked egress. Safety guardrails triggered on the literal word 'exploit' and collapsed when the prompt was rephrased as 'vulnerability reproduction.' Docker isolation failed twice. What held was an RPC proxy allow-listing eth_* methods and blocking anvil_* debug methods.

The inverse number from the same study matters more than the eval correction: structured domain skills lifted true success from 10% to 70% on the same model. A 4.2M-parameter scheduling head moved LLaDA-8B from 22% to 60.7% on GSM8K with the base weights frozen. The moat isn't the base model anymore. It's the verifier suite, the skill scaffolding, the method-level proxy that decides what the agent can actually call. Every agent deployment from here should start from a blast-radius diagram and a list of allow-listed tool methods, not a system prompt.

What to do this week

Three concrete moves before Friday. First, inventory every third-party tool — security, observability, cost, anything — that holds production credentials, and revoke anything you can't verify clean against pre-March known-good state. KICS and Anodot are the named ones, not the only ones. Second, re-tokenize a representative week of Opus traffic against the 4.7 vocabulary and present the cost delta to finance before the invoice does. Third, for any agent with tool access, replace network-layer isolation with a method-level egress proxy. Allow-list eth_*, deny anvil_*. The principle generalizes — the agent will find the second path when you block the first, and the second path is almost always a debug or introspection method nobody thought to scope.

The perimeter is the vendor list, the CI runner, and the token's scope. The bill is whatever the tokenizer says it is this quarter.
