During the TrustDefender Labs tests the Gozi Trojan was invisible to all leading anti-virus software, allowing it to infiltrate and attack user’s systems and browsers. The new Gozi variant has many of the same characteristics of its predecessor (researched 12 months ago) however, is showing increasing sophistication in HTML injection compared to other Trojans. Gozi perpetrators have been successfully evading signature patterns so consistently that the evolution of the Trojan has been relatively unknown. This highlights the potential risks and impacts of attacks on financial institutions, businesses and individuals whilst staying predominantly undetectable to any anti-virus software.
Online Security expert and CTO of TrustDefender, Andreas Baumhof comments; “Gozi is unbelievably good at staying under the radar from an infection point of view, but this particular sample also used SSL and HTTPS against the good guys. Typically designed to protect us, the fraudulent use of HTTPS helps them to stay virtually invisible for their C&C server connection. Alarmingly we are coming across an increasing number of Trojans that are using SSL and HTTPS to cover their tracks. The other thing that impressed us was the extensive client-side logic to circumvent even Two-Factor Authentication. Unfortunately this is becoming more common as we see similar techniques with Trojans such as Zeus, Spyeye, Carberp.”
Why should we be worried about Gozi?
-- Gozi is one of the most sophisticated Trojans out there with an impressive feature set.
-- Gozi can use encrypted HTTPS connection for its C&C server communication with a valid certificate meaning it can evade detection.
-- Traditional anti-virus software is unable to detect the Gozi Trojan
-- Gozi enables real time account takeover that even works with Two-Factor Authentication.
