The OCU warns of the dangers of bluesnarfing: tips to avoid being hacked

In the complex world of cybersecurity, bluesnarfing has emerged as a significant threat to users of mobile devices and other devices with Bluetooth technology. This hacking technique, whose name combines “Bluetooth” and “snarf” (slang for copying without permission), allows criminals to access sensitive personal data without consent.

Although bluesnarfing is not new, its persistence and danger have led organizations such as the Organization of Consumers and Users (OCU) and the Bank of Spain to issue regular alerts. It exploits Bluetooth vulnerabilities to gain unauthorized access to information such as passwords and banking details, as long as the target device has Bluetooth enabled and is within range of the attacker, which can reach up to 240 meters with advanced versions of the device. Bluetooth protocol.

Defense against bluesnarfing begins with basic safety measures. It’s crucial to keep Bluetooth disabled when it’s not actively being used for connections, such as with wireless headphones or compatible car devices. This simple precaution can prevent hackers from accessing our devices remotely.

Additionally, it is essential not to accept Bluetooth connection requests from unknown devices. Even without our explicit approval, attackers can exploit known vulnerabilities in outdated operating systems. Therefore, keeping our devices updated with the latest security patches is a crucial defense against these cyber attacks.

One of the most well-known Bluetooth vulnerabilities, Blueborne, Discovered in 2017, it affected billions of devices worldwide. Although subsequent updates have mitigated this threat, users of older devices should be especially careful and consider updating their operating systems if they have not already done so.

Prevention against bluesnarfing focuses on awareness and proactive action. By keeping our devices up to date and Bluetooth disabled when not needed, we can protect our personal information from unwanted intrusions and stay one step ahead in cyber protection.
