MacSync under the microscope: new delivery methods and a new payload
MacSync is a relatively young, rapidly evolving family of crypto/info stealers. First advertised on the dark web in 2025 as Mac.c, the stealer was later renamed to MacSync by its creators. The initial versions were implemented as AppleScripts and closely resembled the AMOS stealer family, but over time, MacSync developed distinctive features of its own, including a backdoor module. In this report, we discuss a new infection chain that differs significantly from previous variants. We first…

New Android malware uses AI to steal bank logins and PINs

T-Mobile rewards points expiry texts are a phishing scam
Since early May 2026, we’ve been monitoring a large phishing campaign based on T-Mobile rewards points. The messages falsely warn that a customer’s rewards points are about to expire.
