Background for this topic.
Wireless systems transmit data over radio or other electromagnetic links rather than a physical cable, including Wi-Fi, Bluetooth, cellular, and many IoT protocols. The tag usually covers the security of these protocols, access points, client devices, and radio-enabled equipment—not every use of the word “wireless.”
Because signals can extend beyond controlled spaces, an attacker within range may capture traffic, attempt unauthorized association or pairing, impersonate a legitimate access point, or disrupt service through interference. Encryption alone does not prevent these attacks: use secure authentication, current protocol configurations, protected management interfaces, and segmentation between wireless clients and sensitive networks. Track firmware and protocol vulnerabilities, remove obsolete security modes, monitor for rogue devices and unusual associations, and review wireless logs during investigations. Bluetooth and IoT deployments also require attention to default credentials, discoverability, and unnecessary exposed services.

Researchers tested their theory on nine chargers, each different and available to consumers, and found them all vulnerable to their attacks.
Cybersecurity researchers have identified two authentication bypass flaws in open-source Wi-Fi software found in Android, Linux, and ChromeOS devices that could trick users into joining a malicious clone of a legitimate network or allow an attacker to join a trusted network without a password
A team of academic researchers show that a new set of attacks called 'VoltSchemer' can inject voice commands to manipulate a smartphone's voice assistant through the magnetic field emitted by an off-the-shelf wireless charger. [...]
