The malicious computer program used against Target was revealed in a government report released yesterday.
Officials are calling the cyber attack operation "Kaptoxa," a Russian word that comes from a piece of code in the malware. Investigators say the malware used in the recent breach was partly written in Russian, though it's unclear whether the attack originated in Russia.
