Hi everyone,
I run a digital sheet music store on Shopify and wanted to share what I’ve been dealing with over the past several weeks in case others are experiencing the same thing.
Since January 2026, a bot has been systematically creating fake customer accounts in my store. Here is what I know about it:
The bot uses the user agent okhttp/5.3.2, which is distinct from the legitimate Shopify integration user agent okhttp/3.14.1. It rotates through a fixed pool of exactly 15 fake name pairs (Emma Smith, Alexander Rodriguez, James Bond, etc.) with bot-generated emails across gmail, outlook, hotmail, yahoo and icloud. It creates customer records with no associated orders, hitting the customer creation endpoint directly and bypassing the checkout flow entirely. As of today it has created 2,066 fake accounts, which is 56% of my entire customer database.
I have an open high-priority ticket with Shopify engineering (ticket 65542765). Their findings confirmed the bot signature and acknowledged it is part of a wave targeting multiple stores. However their position is that they cannot block a specific user agent at store level, and a request for escalation to Merchant Success was declined. The recommended solution is to purchase a third-party app.
My concern is twofold. First, a clearly identified bot signature that is hitting multiple stores is a platform issue, not a per-store issue. Second, most merchants without technical knowledge would never identify this or get this far with support. They would simply have their CRM silently polluted with no explanation.
Has anyone else seen the okhttp/5.3.2 signature in their store? And has anyone had success with Shop Protector or Negate stopping it?
