Dynamic steganographic embeddings for message threat detection

A method comprising:

• at a computing platform comprising at least one processor, a communication interface, and memory:
• pushing, to a client device, an electronic messaging plugin configured to validate steganographic modifications, embedded in electronic messages by the computing platform;
• intercepting an electronic message directed to the client device;
• generating a steganographic modification to the electronic message, wherein generating the steganographic modification comprises generating a modification of a different type than a previously generated steganographic modification;
• embedding, in the electronic message, the steganographic modification, resulting in a modified electronic message, wherein embedding the steganographic modification comprises embedding the steganographic modification in location of the electronic message different than a location in which the previously generated steganographic modification was embedded in a previous message;
• and
• sending, to the client device, the modified electronic message, wherein the client device is configured to validate, using the electronic messaging plugin, the steganographic modification prior to launching the modified electronic message at the client device.

One or more non-transitory computer-readable media storing instructions that, when executed by a computing platform comprising at least one processor, a communication interface, and memory, cause the computing platform to:

• push, to a client device, an electronic messaging plugin configured to validate steganographic modifications, embedded in electronic messages by the computing platform;
• intercept an electronic message directed to the client device;
• generate a steganographic modification to the electronic message, wherein generating the steganographic modification comprises generating a modification of a different type than a previously generated steganographic modification;
• embed, in the electronic message, the steganographic modification, resulting in a modified electronic message, wherein embedding the steganographic modification comprises embedding the steganographic modification in location of the electronic message different than a location in which the previously generated steganographic modification was embedded in a previous message;
• and
• send, to the client device, the modified electronic message, wherein the client device is configured to validate, using the electronic messaging plugin, the steganographic modification prior to launching the modified electronic message at the client device.
