Show ▼
The PolarEdge botnet is using a custom TLS backdoor on compromised devices, enabling encrypted control and stealthy management across a large IoT footprint. The botnet reaches enterprise-grade firewalls and consumer devices such as routers, IP cameras, and VoIP phones. With signs of activity since June 2023 and roughly 40,000 active devices this month, the network represents a persistent abuse platform with broad relay potential.

Apple broadened availability of iOS 18.7.7 and iPadOS 18.7.7 on April 1 to more devices still running iOS 18, including iPhone XR through iPhone 16 models, iPhone SE (2nd and 3rd generation), and multiple iPad models, so they can receive security patches against DarkSword web-based watering hole attacks that can deploy malware after a user visits a compromised website. Apple also began sending lock screen notifications to users running older software, urging installation of the latest security updates.
