Carbanak is an APT-style campaign targeting (but not limited to) financial institutions that was claimed to have been discovered in 2015 by the Russian/UK Cyber Crime company Kaspersky Lab who said that it had been used to steal money from banks. The malware was said to have been introduced to its targets via phishing emails. The hacker group was said to have stolen over 500 million dollars, or 1BN dollars in other reports, not only from the banks but from more than a thousand private customers.
The criminals were able to manipulate their access to the respective banking networks in order to steal the money in a variety of ways. In some instances, ATMs were instructed to dispense cash without having to locally interact with the terminal. Money mules would collect the money and transfer it over the SWIFT network to the criminals’ accounts, Kaspersky said. The Carbanak group went so far as to alter databases and pump up balances on existing accounts and pocketing the difference unbeknownst to the user whose original balance is still intact.
Their intended targets were primarily in Russia, followed by the United States, Germany, China and Ukraine, according to Kaspersky Lab. One bank lost $7.3 million when its ATMs were programmed to spew cash at certain times that henchmen would then collect, while a separate firm had $10 million taken via its online platform.
Kaspersky Lab is helping to assist in investigations and countermeasures that disrupt malware operations and cybercriminal activity. During the investigations they provide technical expertise such as analyzing infection vectors, malicious programs, supported Command & Control infrastructure and exploitation methods.
