A key you never rotate is a key that's valid forever, including the version of it that leaked to a public commit two years ago. Here's what attackers actually do with stolen keys, why detection rarely saves you, and what scheduled rotation actually limits.
Detection-only strategies are losing. Limiting the exposure window is the control that scales.

The damage varies by key type. The pattern is consistent.
Inference runs against your quota or balance until exhausted. A single weekend on a leaked key with no spend cap can cost $5,000 to $50,000 depending on the model.
Spin up GPU or compute fleets to mine cryptocurrency or to launch attacks. Bills hit five or six figures before detection. Cloud providers sometimes waive charges, sometimes don't.
Create test charges to validate the key, then move on to fraudulent charges, refunds routed to attacker cards, and exfiltration of customer payment metadata.
SendGrid, Twilio, Mailgun keys get used for phishing campaigns from your verified sender domain. Your IP and domain reputation tank. Your customers receive phishing emails.
Read access to user records, password hashes, API logs. Quiet exfiltration is the norm, often discovered months later when records show up on a breach forum.
Stripe metrics, Mixpanel data, Segment streams. Competitive intelligence is the goal: attacker reads your funnel, revenue, churn, and customer list at their leisure.
Every team writes a strict policy banning secrets in source control. Most teams hold that line. Keys still leak. The reason: there are more leak channels than the obvious one.
You cannot reasonably close every channel. Rotation is the compensating control. It says: we accept that leaks happen, and we cap the useful lifetime of every key so the leak eventually goes cold on its own.
A 90-day rotation costs roughly 30 minutes of engineering time per key, every 90 days. For a team with 20 production keys, that's about 10 hours per quarter. The cost of one successful breach is in IBM's most recent report: $4.88 million on average.
That math is heavily skewed for any team with revenue: spending 10 hours a quarter to meaningfully reduce the probability of a seven-figure incident is one of the cheapest risk reductions available. The reason it doesn't happen consistently isn't cost. It's memory. People forget tasks scheduled 90 days out.
See the main API key rotation reminder page for the full picture, or read the rotation checklist for the process that runs every 90 days.
Set a 90-day reminder. The leak might already be live. The next rotation closes it.
Done in seconds. No sign-up required.
A scraper finds it within minutes. Public GitHub commits, in particular, are continuously crawled by bots that test exposed keys against the matching service. Once validated, the key gets used or sold. For OpenAI and cloud provider keys, attackers run inference or mining workloads on your account. For data API keys, they extract whatever the key can read.
Research from Truffle Security and GitGuardian has shown that a freshly committed AWS access key in a public repo is typically probed within minutes. Some report exploitation in under a minute. The attack surface is automated, so the lag is essentially zero.
Whatever the key is scoped to do. For OpenAI: run inference until your quota or balance is exhausted. For AWS: spin up GPU instances for mining or launch attacks from your infrastructure. For Stripe live keys: create charges, refund to attacker cards, exfiltrate customer payment metadata. For database keys: read or modify customer data.
Major providers do detect some abuse and suspend keys when patterns trip their fraud systems, but detection lags hours to days, and the bill is often already in the thousands. Cloud providers will sometimes waive charges for first-time leaks if you have proof of when the leak happened and how quickly you rotated. Sometimes is not always.
You're safer. You are not safe. Keys also leak through error logs sent to external monitoring services, screenshots in support tickets, browser dev-tools network panels recorded during user research, contractor laptops, third-party CI logs, leaked database backups, and dependency packages that exfiltrate env vars. Rotation is the assumption-of-compromise control.
It caps the useful life of any stolen key. A key compromised on day one of a 90-day cycle has at most 90 days of attack value. Without rotation, the attack window is forever. You can't catch every leak, but you can limit how long each one stays profitable.
