KRACK Attacks: Defending Your IT Service Data in 2018

Braintek Staff Security Alerts

IT service security professionals recently discovered yet another strategy attackers use to intercept information when Wi-Fi users join a network. In many cases, sensitive information like passwords and credit card information are captured and later used by the hacker. At this point, it’s important everyone understands what KRACK is and how it can infiltrate a system.

Understanding How KRACK Impacts a System

According to industry experts, KRACK is an acronym used to describe a Key Reinstallation Attack. Whenever a new user attempts to join a Wi-Fi network, a one-time key is generated. That key allows the user’s device to communicate with the Wi-Fi network. The network then believes the user has the proper credentials to join the network.

Once that relationship is established, the network provides an encryption key to protect both the new user and the network itself. When employing a KRACK, the attackers force the network to reinstall the same key, giving the attacker’s device access to the information being sent or received.

Is There a Real Threat to Most Users?

The short answer is yes. Virtually anyone using a Wi-Fi supported device is at risk. Network security and IT service experts stress, however, that some systems are more vulnerable than others. Devices using Linux and Android devices running newer versions of the operating system are currently threatened to a greater degree than other devices.

However, as with previous threats, there is always a potential for other devices to be compromised in the future. It’s always wise to discuss the potential threats to Wi-Fi systems and users with a security expert to determine the threat level present. Houston businesses, for example, are encouraged to contact Braintek to evaluate their systems and recommend strategies for avoiding attacks.

Develop a Defense Strategy

Since the posing threat is real to Houston-area businesses, Braintek suggests companies take steps now to mitigate any potential attack. There are specific ways to protect vulnerable systems and equipment from KRACK in 2018.

As with other threats, the IT service providers from Braintek strongly recommend updating devices like smartphones, tablets, and laptops that routinely use Wi-Fi. Many device manufacturers are already in the process of releasing updates that provide some level of protection.

Routers should also be updated as soon as possible to protect systems. Current system vulnerabilities are being addressed, but those using KRACK are also likely to introduce new ways to hack systems. That simply means everyone involved is encouraged to update devices as soon as patches are introduced.
