Unlike in the pre-internet era, when trading in the stock or commodities market involved a phone call to a broker -- a move which often meant additional fees for would-be traders -- the rise of trading apps placed the ability to trade in the hands of ordinary users. However, their popularity has led to their abuse by cybercriminals who create fake trading apps as lures for unsuspecting victims to steal their personal data. We recently found and analyzed an example of such an app, which had a malicious malware variant that disguised itself as a legitimate Mac-based trading app called Stockfolio. We found two variants of the malware family. The first one contains a pair of shell scripts and connects to a remote site to decrypt its encrypted codes while the second sample, despite using a simpler routine involving a single shell script, actually incorporates a persistence mechanism.
