8. A system for detecting illegitimate out-of-band authentication attempts, the system comprising: a memory; an identification module, stored in the memory, that determines that a text message comprises a confirmation code for an out-of-band authentication procedure based on at least one of: a format of the text message; a source of text message; a detection module, stored in the memory, that detects an attempt to access the text message; a determination module, stored in the memory, that determines that the attempt to access the text message was configured to avoid participation by a user of a device on which the attempt to access the text message occurred; a remediation module, stored in the memory, that performs, in response to determining both that the attempt to access the text message was configured to avoid participation by the user and that the text message comprises the confirmation code for the out-of-band authentication procedure, a remediation action that addresses an illegitimate out-of-band authentication attempt, the illegitimate out-of-band authentication attempt comprising the attempt to access the text message, wherein the remediation action comprises at least one of: blocking the attempt to access the text message; warning a user of the attempt; warning a sender of the text message of the attempt; disabling an application with a permission to access text messages; at least one physical processor that executes the identification module, the detection module, the determination module, and the remediation module.
