Grandoreiro is a malware family classified as a backdoor and spyware, first seen in April 2020, and is consistently described as a banking trojan focused on credential theft, remote fraud enablement, and control of compromised Windows systems. It has remained active through recurring campaigns, including a renewed wave in May and June 2026 that concentrated heavily on Latin America, especially Mexico, while also reaching parts of Europe and North America.

On October 21, 2026, PHP shipped emergency fixes for two flaws that let anyone on the internet run code on a PHP web server, with no login. The weakness behind them had been flagged in 2024 and then sat, partly because nobody had proved it was exploitable. In 2026, researchers working with AI models proved it within days. Exploit attempts started before the fix shipped, and details leaked a day ahead of schedule. That sequence is the real story of PHP2Shell. The bug matters, but speed matters more.

TOTP (Time-Based One-Time Password) is an authentication algorithm that generates a unique, temporary numeric code using the current time as a moving factor. Typically, these codes are six digits long and automatically change every 30 seconds, providing a one-time verification code for authentication. TOTP uses a shared secret between the authentication service and the user's authenticator device, combining that secret with the current time to generate each code.

OAuth (Open Authorization) is an open-standard authorization framework that allows applications to access an end user's protected resources without requiring the user to share their password. Instead, users grant applications limited access to specific resources through authorization, while their credentials remain private. OAuth uses access tokens to control what an application can access on a user's behalf.
