AnonyMousKIT PhaaS uses voice AI agents to phish iPhone passcodes

BleepingComputer

A new phishing-as-a-service platform named AnonyMousKIT has been discovered, which automates the process of stealing passcodes from iPhones. This service utilizes voice AI agents to trick users into providing their unlock codes, specifically targeting those who have had their Apple devices stolen. Once attackers obtain the passcodes, they can disable the Activation Lock, allowing them to access and potentially resell the stolen devices. This poses a significant risk to iPhone users, as it could lead to increased theft and exploitation of stolen devices. Users are urged to remain vigilant and skeptical of unsolicited calls requesting sensitive information.

Water sector passes, government sector fails attempts to spot and halt simulated CISA attack

CyberScoop

In a recent cybersecurity test, red-teamers conducted simulated attacks on both the water and government sectors to evaluate their response capabilities. The water sector successfully identified and contained the simulated threats, effectively preventing any further access. In contrast, the government sector failed to manage the attack, allowing the red-teamers to gain initial access without detection. This incident illustrates the varying levels of preparedness among critical infrastructure sectors and raises concerns about the government's ability to secure sensitive systems against potential real-world attacks. The implications of such failures could be significant, especially given the importance of both sectors in maintaining public safety and national security.
