Disclosed are various embodiments for detecting security breaches using watchdog transaction accounts. A security agent can initiate a purchase with a first electronic commerce system and provide a watchdog transaction account as payment for the purchase. The security agent can then store a record of the purchase which includes a merchant identifier for the merchant and the watchdog transaction account. Subsequently, a transaction authorization system can determine that authorization for a transaction with second electronic commerce system failed. If the transaction authorization system determines that the account used in the transaction with the second electronic commerce system, then the transaction authorization system can determine that the first electronic commerce system has suffered a security breach.

A merchant server may integrate device identifying code into a webpage. In response to a device accessing the webpage, the device identifying code may cause the merchant server to obtain characteristics of the device. A device registry may compare the characteristics of the device with known device profiles to determine a risk level of the device. A transaction account issuer may utilize the risk level in performing an authorization evaluation.
