INTELLIGENT BRANDS // Enterprise Security Growing West African cyber syndicate cannot be ignored West African cybercrime operations have matured from Yahoo boys style and will likely soon reach the scale of global threat actors. The Internet aids cybercriminals to do two essential things in order to steal money from victims—create fake personas and attempt to defraud as many victims as possible. Creating personas usually involves obtaining several email addresses for various online profiles, even on social media, to support acts of fraud. Performing fraud against potential victims, meanwhile, involves sending them socially engineered emails and messages. As early as 2012, Trend Micro predicted that we would see a cybercriminal underground market emerge from the Western Africa region. To more clearly map the landscape, Interpol conducted a survey among its member countries in West Africa. The countries covered by the Interpol Regional Bureau for West Africa include Benin, Burkina Faso, Cape Verde, Côte d’Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone and Togo. Two major types of cybercriminals reign in West Africa, so-called Yahoo boys and next-level cybercriminals. Yahoo boys excel in committing simple types of fraud, advance-fee, stranded-traveler and romance scams-fraud under the supervision of ringleaders or masterminds. Next-level cybercriminals, meanwhile, are 44 INTELLIGENTCIO more experienced and prefer to pull off long cons business email compromise or BEC and tax scams-fraud or crimes that require more time, resources, and effort. They use malware keyloggers, remote access tools-Trojans or RATs, and other crime-enabling software email-automation and phishing tools, crypters, that are easily obtainable from underground markets. West African cybercriminals have one skill they are particularly good at—defrauding victims. But why resort to cybercrime? It is actually quite simple, almost half of the 10 million graduates from more than 668 African universities each year do not find employment. According to the Interpol survey, West African law enforcement agencies recognise that about 50% of the cybercriminals that they identified in the region are unemployed. Note that West African cybercriminals are far more trusting than their French counterparts, according to previously published Trend Micro research. They constantly communicate with one another. They do not hesitate to share know-how with fellow cybercriminals. This is actually how newbie cybercriminals learn to defraud potential victims and eventually differentiate themselves from others. Advance-fee fraud also known as 419 fraud in the Nigerian Penal Code, romance fraud, and the newer BEC fraud are not only committed by known groups. Novices start off committing 419 fraud then move on to more complicated schemes such as BEC fraud. Cybercriminal gangs, meanwhile, may prefer to pull off romance or BEC fraud. It all just depends on their preferences, needs, and available resources. The Interpol survey confirms that a West African cybercriminal group will generally commit multiple types of fraud. Yahoo boys, dubbed such due to their heavy use of Yahoo! apps for communication via email and instant messaging IM in the early 2000s, are www.intelligentcio.com
