Your DSLR could be vulnerable to malware and ransomware

Your DSLR could be vulnerable to malware and ransomware”

According to Check Point's report, this is possible through the picture transfer protocol of the cameras. The Picture Transfer Protocol (PTP) is an easy target for the attack since this standard enables these digital cameras to not only transfer photos but also upgrade the camera's firmware. First of all, don't connect to Wi-Fi networks or desktops that you don't know, disable the networking functionality when you're not using it, and make sure to upgrade the firmware on your camera as soon as possible.

In order to avoid falling victim to this type of attack, both companies advised users to ensure that their cameras are using the latest firmware and install patches if/when they become available. The standardized protocol for transferring images from a camera is the Picture Transfer Protocol (PTP). The attackers could hold the photos hostage until the user pays the ransom after an attack. In particular an attacker making use of an infected WiFi access point could use that vulnerability to plant malware onto the camera, encrypting the data stored on the SD card, or indeed later encrypting a user's PC or notebook.

Given that the protocol is standardised and embedded in other camera brands, the researchers believe similar vulnerabilities can be found in cameras from other vendors as well.

Following the research, Check Point contacted Canon about the vulnerability and the company (after confirming it) issued a security advisory as part of the patch for the glitch.

In an official blog post Canon acknowledges, "due to these vulnerabilities, the potential exists for third-party attack on the camera if the camera is connected to a PC or mobile device that has been hijacked through an unsecured network". It's also recommended that camera owners leave the device's Wi-Fi turned off when it is not in use. On top of this, Check Point said "Canon has an extensive modding community, called Magic Lantern", which is an "open-source software add-on that adds new features to the Canon EOS Cameras". However, to carry out this attack, the hacker has to be close to the access point.

Check Point Software Technologies Ltd. Security researchers have now warned that even DSLR cameras are not immune to ransomware and malware attacks.

The lack of security practices such as misconfiguration and poor management of the Cloud resources remains the most prominent threat to the Cloud ecosystem in 2019, subjecting Cloud assets to a wide array of attacks.
