Broadcom Wi-Fi chipset Found in iPhone 4 is Vulnerable To External Attacks

Core Security has discovered a vulnerability in the last two firmware updates for the Broadcom wireless chip (BCM4325 and BCM4329). These chips can be found in different devices such as the iPhone 4, iPad, iPad 2, some Android devices and some models of Ford cars. The flaw in this Broadcom chip makes the devices vulnerable to external procedures that cause Wi-Fi to become unusable for the duration of the attack.

According to Core Security's explanation, the hacker only needs to have a wireless card that supports 802.11 to explore the chip's vulnerability. Once the hacker is finished with the attack, the device returns to working properly and it seems that there is no risk to the data stored on the devices. The only consequence, during the attack, is the inability to use your Wi-Fi.

Here is the complete list of devices that have the two indicated Broadcom wireless chips:


  • Apple iPhone 3GS
  • Apple iPod 2G
  • HTC Touch Pro 2
  • HTC Droid Incredible
  • Samsung Spica
  • Acer Liquid
  • Motorola Devour
  • Ford Edge (yes, it's a car)


  • Apple iPhone 4
  • Apple iPhone 4 Verizon
  • Apple iPod 3G
  • Apple iPad Wi-Fi
  • Apple iPad 3G
  • Apple iPad 2
  • Apple Tv 2G
  • Motorola Xoom
  • Motorola Droid X2
  • Motorola Atrix
  • Samsung Galaxy Tab
  • Samsung Galaxy S 4G
  • Samsung Nexus S
  • Samsung Stratosphere
  • Samsung Fascinate
  • HTC Nexus One
  • HTC Evo 4G
  • HTC ThunderBolt
  • HTC Droid Incredible 2
  • LG Revolution
  • Sony Ericsson Xperia Play
  • Pantech Breakout
  • Nokia Lumina 800
  • Kyocera Echo
  • Asus Transformer Prime
  • Malata ZPad
Let's hope the manufacturers of the Broadcom chip are hard at work to develop an update that will restore the security level and prevent attacks in the near future. This is a significant amount of devices, and therefore the majority of people walking around today are more than likely to have at least one, if not several of these devices listed, so a fix should be of the utmost importance for this Broadcom chip. [Via iPhoneItalia]
