Citadel V1.3.5.1: Enter the Fort’s Dungeons

What can be said about the Citadel Trojan that we have not yet said? This advanced banking Trojan, exclusively available in the deep web, has been a game changer ever since it appeared in the most clandestine of cybercrime communities.

Fit for crime king(-pins), it was built over the old Zeus’ (v2) source code, exceeding its predecessor by far and breathing new air into Trojan-facilitated cybercrime. Possessing many of Zeus’ best features and mechanisms, Citadel is continuously renovated by its developers, adding new and innovative modules designed for enhanced control over infected bots and clever victim impersonation schemes.

True to its dictionary definition:“a fortress that commands a city and is used in the control of the inhabitants”; the Trojan flavor is no different, commanding botnets and controlling its zombies.

As of the October release of v1.3.5.1 “Rain Edition”, this crimeware is at its 6th release, and costs 41% more than it did on its January ‘12 debut. Citadel’s basic kit’s off-the-shelf price now stands at $3,391 USD/€2,630, (up from $2,399 USD/€1,850). Although some would argue the price is right, with today’s complete absence of up to par varieties in the underground, botmasters have no other choice but to pay up.
