Με τις έξυπνες συσκευές να έχουν μπει για τα καλά στην καθημερινή ζωή μας, οι κίνδυνοι παραβίασης δεδομένων έχουν αυξηθεί κατακόρυφα. Οι hackers δεν προσπαθούν πλέον να παραβιάσουν τον υπολογιστή σας αλλά βρίσκουν νέες οδούς μέσω των έξυπνων συσκευών. Ένα τέτοιο παράδειγμα μας υπόδειξαν ερευνητές που αυτή την φορά βρήκαν τρωτά in Philips Hue Smart Light Bulbs.

Her researchers Check Point revealed today a new, high-severity vulnerability affecting Philips Hue Smart Light bulbs. This vulnerability, codenamed CVE-2020-6007, can give hackers the ability from a distance of 100 meters to gain access to a targeted WiFi.

The underlying vulnerability lies in the way Philips implemented the Zigbee communication protocol in its smart light bulb. ZigBee is a widely used wireless technology, designed to allow every να επικοινωνεί με οποιαδήποτε άλλη συσκευή στο δίκτυο. Το πρωτόκολλο έχει ενσωματωθεί σε δεκάδες εκατομμύρια συσκευές σε όλο τον κόσμο, συμπεριλαμβανομένων των Amazon Echo, SmartThings, Belkin Emo and more.

The researchers did not disclose the full technical details of the vulnerability in order to give reasonable time to the affected manufacturers to apply the fixes. However, they shared a video showing the attack.

As seen in the video, in the attack scenario the hackers use a known bug (which has been detected in the past) to take control of the Hue lamp. This makes the device 'unreachable' to the users control application, forcing them to delete the lamp and then try to connect to it again.

The application on the mobile phone scans the area, checking for the existence of smart devices and thus discovers the hacker-controlled smart lamp with updated firmware. The user adds it back to his network.

The hackers then exploit the vulnerabilities of the ZigBee protocol to overload the cache of the Hue lamp-mobile phone-network connection, allowing them to install malware on that interface. Beyond that, hackers can use malware to infiltrate the network.

Check Point reported these vulnerabilities to Philips and Signify, owner of the Philips Hue brand, in November 2019, which just last month released an updated, patched firmware for the device.

If you do not have the firmware update feature enabled, we recommend that you install it manually immediately, and at the same time change the settings to refresh future updates.
