RSA Monthly Online Fraud Report - June 2013

  1. 1. F R A U D R E P O R TBUGAT TROJAN JOINSTHE MOBILE REVOLUTIONJune 2013RSA researchers analyzing Bugat Trojan attacks have recently learned that Bugat’sdevelopers managed to develop and deploy mobile malware designed to hijackout-of-band authentication codes sent to bank customers via text messages.Bugat (aka: Cridex) was discovered and sampled in the wild as early as August 2010.This privately-owned crimeware’s earlier targets were business and corporate accounts,its operators attempting high-value transactions ($100K-$200K USD per day) in bothautomated and manual fraud schemes. It is very likely that Bugat’s operators startedseeing a diminished ability to target high-value accounts due to added authenticationchallenges, forcing them to resort to developing a malware component that is alreadyused by many mainstream banking Trojans in the wild.BITMO: A LITTLE LATE IN THE GAME?In somewhat tardy fashion, Bugat joins the lineup of banking malware that makes use ofSMS capturing mobiles apps. The first occurrences of such malware were observed in useby Zeus and SpyEye Trojan variants, which were respectively dubbed ZitMo and SPitMo(Zeus-in-the-Mobile, SpyEye-in-the-Mobile). In mid-2012, RSA coined the name CitMo todenote the Citadel breed of in-the-Mobile activity. The fourth Trojan for which maliciousapps were discovered was Carberp in early 2013, and with this case, Bugat is the mostrecent banking Trojan to have its own SMS-forwarding app, now coined BitMo.WEB INJECTIONS PAVE THE ROADAmong other banking Trojan features, Bugat comes with a set of HTML injections foronline banking fraud and possesses Man-in-the-Browser script functionality. This veryfeature is what allows it to interact with victims in real time and lead them to download
  2. 2. page 2the BitMo mobile malware to their Android/BlackBerry/Symbian devices. iOs remainsalmost entirely exempt from this type of malware since the Apple policy limits appdownloads from third party sites.Bugat’s operators are not doing anything novel. Much as observed in the case of Citadel-in-the-Mobile (which emerged in May 2012), the malware’s developers created classicweb injections, albeit very visually-appealing, designed to show up on the client-sideand communicate social engineering messages to the victim.When Bugat-infected online banking customers access their financial provider’s loginpage, the Trojan is triggered to dynamically pull a relevant set of injections from theremote server, displays them to the victim and leads them to the BitMo download underthe guise of AES encryption being adopted by the bank.The malware requests application permissions linked with the SMS relay, while the nextinjection on the PC side requests that the victim enter a code appearing on the mobiledevice – connecting the infected PC and the mobile handset. Once installed anddeployed BitMo begins hijacking and concealing incoming text messages from thebank, disabling the phones’ audio alerts, and forwarding the relevant messages to itsoperators’ drop zones. Bugat’s entrance to the mobile space only demonstrates theincreasing use of SMS-forwarders as part of Trojan-facilitated fraud.IN-THE-MOBILE MALWARE EVERYWHEREAlthough the injection set created by Bugat’s developers, as well as the distributionmechanism designed for delivering APKs/BlackBerry OS BitMo apps are indeedsophisticated, the actual malware apps are rather basic and show no innovation.That being said, it is very clear that all banking Trojans, both commercial and privatelyoperated codes, are increasingly making use of SMS-forwarders in their criminaloperation.
