Pylcasa
Pylcasa is an Android dropper/Trojan reported by Kaspersky as operating primarily in Brazil in 2025. It was observed infiltrating Google Play while masquerading as simple benign applications such as calculators. Once launched, the app opens a URL supplied by the threat actor. Reported follow-on behavior includes redirecting victims to phishing pages or illicit online casino sites, and Kaspersky described it as behaving similarly to Trojans from the Fakemoney family. Activity involving Pylcasa was described as concentrated in Brazil. High-confidence characteristics from the reporting are limited to its Android/mobile context, Google Play distribution via fake utility apps, URL-opening/redirection behavior, and use in campaigns leading users to phishing or illegal gambling pages. No specific threat actor attribution or concrete IOCs were provided in the content.
