Analysis of attacks against trading and bank card system
Group-IB annual report on speculative fluctuations of exchange rate and other incidents in 2015 caused by the Trojan program Corkow (Metel)
View report
Facts about Corkow:
for 6 months
and more the trojan could stay undetected in the system
14 minutes
lasted the attack that caused a high volatility in the exchange rate
20%
reached volatility of the ruble against the dollar during attack (from 55 to 66 rubles)
over 250 000
devices were infected with Corkow worldwide, and the scale of botnet increased daily
Download the report to learn more about:
detailed overview of the incident, when trading system was attacked by Corkow
cybercriminals’ approach and geographic spread of Corkow malware
indicators of compromise and recommendations for defense
technical analysis of the trojan and its functionality
Judging by the method of infecting devices and corporate networks, we can conclude that all infections were conducted on a random “non-targeted” basis. However, as our previous investigations on Anunak group displayed, access to any computer on a corporate network gives access to even the most highly protected banking systems. The attacks against the trading system and bank card system were conducted under the same scenario and thus we can forecast similar attacks against financial institutions in Russia, EU, the Middle East, Asia and the USA in the future.
