November attack: Silence
The message sent on 23 October, also from a fake FinCERT email address, contained five attachments disguised to look like official CBR documents. Among them was a document entitled “Template Agreement on Cooperation with the Central Bank of the Russian Federation on Monitoring and Information Exchange .doc”. Three out of five files were empty decoy documents, but two contained a download for the Meterpreter Stager. To carry out the attack, hackers used self-signed SSL certificates. Furthermore, the server infrastructure involved had been used in the previous attacks conducted by MoneyTaker. All these factors led to the conclusion that MoneyTaker was behind the October attack.
Group-IB experts believe that hackers managed to obtain the samples of CBR documents from earlier compromised mailboxes belonging to employees of Russian banks. MoneyTaker used the information obtained to design emails and documents purporting to be from the CBR to conduct targeted attacks on banks.
“Since July, to share information, FinCERT has been using an automated incident processing system that makes it possible to securely and quickly share information about incidents and unauthorized operations based on the “Feed-Antifraud” database,” comments the Central Bank’s press service. “The backup channel for sharing information is email. All messages sent via email contain FinCERT’s electronic signature.”
