Our Cyber Safety Solutions team identified a malicious Chrome extension we named FacexWorm, which uses a miscellany of techniques to target cryptocurrency trading platforms accessed on an affected browser and propagates via Facebook Messenger. A very small percentage of users were affected by these malicious extensions, and Chrome had already removed many of these extensions prior to being alerted by Trend Micro. FacexWorm isn’t new. It was uncovered in August 2017, though its whys and hows were still unclear at the time. Last April 8, however, we noticed a spike in its activities that coincided with external reports of FacexWorm surfacing in Germany, Tunisia, Japan, Taiwan, South Korea, and Spain.
