Gozi IFSB banking Trojan has rolled out new code, a new botnet and a high level of customization in the latest wave of attacks.
Gozi IFSB, a banking Trojan that has been making the rounds of the internet for several years, is back with new targets, new characteristics, and a new botnet for distribution. The changes, detailed by Talos Intelligence on Tuesday, serve to make the Trojan a more dangerous threat to a select group of victims.
Gozi IFSB has begun to use the Dark Cloud botnet in recent campaigns, a development that shows the attackers are moving to infrastructures that are associated with widespread criminal and malicious activity. Dark Cloud, which uses compromised personal computers as hosts for websites that change addresses every few minutes, is based primarily in Eastern Europe and Russia.
