Flashpoint analysts monitoring a top-tier Russian hacking forum recently observed an actor who goes by the pseudonym "flokibot," developing a Trojan known as "Floki Bot." While the malware uses source code from the ZeuS Trojan, the actor reinvented the initial dropper process injection to instead target point-of-sale (PoS) terminals. The Floki Bot Trojan is not only representative of the increasingly-collaborative nature of cybercrime, it also illustrates the growing presence of "connectors" within the Deep and Dark Web.
Flashpoint defines "connectors" as individuals who interact on Deep & Dark Web forums maintained outside of their country of residence. These individuals make efforts to communicate outside their native language in order to obtain and import knowledge and tools back to their native communities.
Flokibot is a prime example of a connector who brings capabilities from top-tier cybercriminal ecosystems to the burgeoning Brazilian underground. While flokibot is active on number of top-tier Russian-hacking and English-language forums, the actor appears to use translation tools and/or intermediaries to communicate, and is most likely not a native Russian- nor English-speaker. In fact, the actor’s use of Portuguese, IP address, user-agent, and compromised victims all indicate that flokibot may be Brazilian.
"Connectors:" A Rising Underground Trend
While flokibot is one notable example, Flashpoint considers the presence of connectors to be a rising trend within the cybercriminal underground. This assessment is based upon a heuristic analysis of actors across several seemingly-disparate Deep and Dark Web forums. The proliferation of open-source learning and translation tools has allowed burgeoning hackers and cybercriminals to communicate across language barriers into Deep and Dark Web forums from which more advanced malware development and tools have been known to emerge.
For those seeking to combat cybercrime, the rising prevalence of connectors is problematic in many ways. First, connectors appear to be contributing to an increase in the number of sophisticated malware samples surfacing from regions that have historically not been prone to cybercrime of this nature. In addition, connectors have also been known to perpetuate fraud schemes across international borders. Although these crimes may not necessarily require technical expertise, many do require physical or privileged access to the targeted institutions and can include insider threats, ATM skimmer installations, and bank drops.
Fraud has not only grown more common as a result, but the perceived profitability of certain fraud schemes continues to attract newer, less-experienced actors eager to capitalize on cybercrime and learn from others within Deep and Dark Web forums. While many would anticipate the profitability of these fraud schemes to consequently decrease, the collaboration of connectors is instead driving innovation. As flokibot has illustrated, cybercriminals are collaborating across regions, advancing their skills, and adapting new techniques to victimize and capitalize on larger populations.
The Growing Pool of Victims
While the expansion of Internet infrastructure in developing countries has indeed spawned connectors, it has also created a larger, more vulnerable population of potential victims that may be less aware of common fraud schemes. The growing amount of Internet-connected users relying upon the virtualization of commercial activities - such as banking and commerce - has rendered even more individuals susceptible to phishing and other cybercriminal schemes. Although many countries have begun enforcing strict legislation to combat cybercrime, many others - particularly developing countries - have yet to implement effective controls. However, as Internet users and government agencies become increasingly aware of common fraud tactics, connectors will likely look externally to develop new skills for launching different types of cybercriminal schemes.
Above all else, it’s crucial to recognize that the presence of "connectors" on the Deep and Dark Web is steadily growing larger and more influential. Cybercrime’s profitability will keep attracting new entrants into communities outside of their native language and nationality. Additionally, sophisticated actors will continue searching for partners to help them perpetrate increasingly advanced fraud schemes and penetrate new markets. In order to both deter and mitigate the risks associated with connectors and cybercrime, intelligence professionals, security teams, and law enforcement officials alike must be agile and proactive in monitoring the cybercriminal landscape. Otherwise, connectors will continue to evade detection, exert a substantial influence over the Deep and Dark Web ecosystem, and exacerbate the risks of future cybercrime.
