A technique provides protection against malicious activity. The technique involves providing a mock token to fraudster equipment. The mock token appears to be a legitimate user token that identifies a legitimate user (e.g., an actual user token, a token seed, etc.). The technique further involves receiving, from the fraudster equipment, an authentication request which uses the mock token and, in response to receiving the authentication request which uses the mock token from the fraudster equipment, performing a set of authentication server operations to protect against future activity by the fraudster equipment (e.g., deny access to the fraudster equipment, acquire specific information about the fraudster equipment, output a message to subscribers of an eFraud network, and so on).

Using mock tokens to protect against malicious activity

A method is performed by a computer in communication with a hardware security module (HSM). The method includes (a) running a process virtual machine (PVM) on the computer, the PVM being configured to execute portable bytecode instructions within a PVM environment and (b) executing, within the PVM environment, instructions for (1) reading encrypted instruction code from data storage of the computer, (2) sending the encrypted instruction code to the HSM, (3) in response, receiving decrypted instruction code from the HSM, and (4) injecting the decrypted instruction code within an application running in the PVM environment for execution by the PVM. Embodiments are also directed to analogous computer program products and apparatuses.

Injecting code decrypted by a hardware decryption module into Java applications

A system for detecting and preventing replay attacks includes a plurality of interconnected authentication servers, and one or more tokens for generating a one-time passcode and providing the one-time passcode to one of the authentication servers for authentication. The system includes an adjudicator function associated with each authentication server. The adjudicator evaluates a high water mark value associated with a token seeking authentication, allows authentication to proceed for the token if the high water mark evaluation indicates that the one-time passcode was not used in a previous authentication, and prevents authentication if the high water mark evaluation indicates that the one-time passcode was used in a previous authentication. The token is associated with a home authentication server that maintains a current high water mark of the token. The home authentication server validates the current high water mark on behalf of the adjudicator function evaluating the token for authentication.
