Security incident 21 Oct 2026: unauthorized charges and request for credit and incident details

Hello Railway team,

After your security incident disclosed on 21 October 2026, a third party used our Gemini API key, which was stored as an environment variable on Railway. Google's anomaly detection flagged the usage the same day: €133.12 observed against a predicted baseline of €0.02. Google declined our refund request, so we are left with €118.35 in fraudulent charges.

We have also lost about one day of developer time rotating every secret in our project, including database credentials, auth keys and deploy keys.

We are asking for:

  1. An account credit covering the €118.35 in fraudulent charges (invoice and Google anomaly report attached). We would appreciate any additional goodwill for the remediation effort.
  2. Confirmation of whether our project was in the affected subset, and which variables were accessed or decrypted, including any sealed variables.
  3. The time window of unauthorized access, and whether any access to databases hosted on Railway was observed.

We need points 2 and 3 to complete our data-breach assessment under GDPR (Art. 33).

Thank you,

René

I'm in a similar boat. I had a gemini key that on Oct 1st was billed $2.22 and then remained unused until the 21st where it was chaged $100 and on the 22nd it was charged $200. I missed the first set of emails, but they did send me emails "Early signal anomaly: Unusual cost spike of $103 on Gemini API in project ". I've since requested a price adjustment but have not heard back yet, my issue is awaiting review. I'm not entirely sure what the total was as the ticket says $336.41 but I was only ever billed for $100 and $200 via email (and on my credit card).

I would appreciate some account credit in good faith for the fraudulent charges. I can provide receipts as necessary.

Same situation here - $100 in Gemini fees billed in a day when usually I'm at under $1 a month.

Is there a way to contact Railway support about these kinds of things?
