The BT switchoff marks a significant change in telecommunications, as BT Openreach plans to discontinue the traditional Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) by 31st January 2027.

A massive botnet of 130,000 compromised devices is launching a relentless assault on Microsoft 365 accounts, using a cunning and sophisticated password-spraying attack. These cybercriminals are exploiting older, less secure "basic authentication" methods to bypass even the most robust security measures—like multi-factor authentication (MFA) and conditional access policies. What makes this attack particularly insidious? It leverages "non-interactive sign-ins," which don’t require user input, making them harder to detect and stop.
