A few months ago, Brian Krebs told the story of the domain corp.com, and how it is basically a security nightmare: At issue is a problem known as “namespace collision,” a situation where domain names intended to be used exclusively on an internal company network end up overlapping with domains that can resolve normally on … Read More “Microsoft Buys Corp.com” »

Free Wi-Fi hotspots can track your location, even if you don’t connect to them. This is because your phone or computer broadcasts a unique MAC address. What distinguishes location-based marketing hotspot providers like Zenreach and Euclid is that the personal information you enter in the captive portal­ — like your email address, phone number, or … Read More “Wi-Fi Hotspot Tracking” »

Researchers have found several vulnerabilities in the WPA3 Wi-Fi security protocol: The design flaws we discovered can be divided in two categories. The first category consists of downgrade attacks against WPA3-capable devices, and the second category consists of weaknesses in the Dragonfly handshake of WPA3, which in the Wi-Fi standard is better known as the … Read More “Vulnerabilities in the WPA3 Wi-Fi Security Protocol” »

The security is terrible: In a very short limited amount of time, three vulnerabilities have been discovered: Wifi credentials of the user have been recovered (stored in plaintext into the flash memory). No security settings. The device is completely open (no secure boot, no debug interface disabled, no flash encryption). Root certificate and RSA private … Read More “Security Analysis of the LIFX Smart Light Bulb” »

Major Bluetooth Vulnerability

Bluetooth has a serious security vulnerability: In some implementations, the elliptic curve parameters are not all validated by the cryptographic algorithm implementation, which may allow a remote attacker within wireless range to inject an invalid public key to determine the session key with high probability. Such an attacker can then passively intercept and decrypt all … Read More “Major Bluetooth Vulnerability” »

Everyone is writing about the new WPA3 Wi-Fi security standard, and how it improves security over the current WPA2 standard. This summary is as good as any other: The first big new feature in WPA3 is protection against offline, password-guessing attacks. This is where an attacker captures data from your Wi-Fi stream, brings it back … Read More “WPA3” »

A Turkish Airlines flight made an emergency landing because someone named his wireless network (presumably from his smartphone) “bomb on board.” In 2006, I wrote an essay titled “Refuse to be Terrorized.” (I am also reminded of my 2007 essay, “The War on the Unexpected.” A decade later, it seems that the frequency of incidents … Read More “Needless Panic Over a Wi-FI Network Name” »
