That digital SLR cameras may be hacked when they are connected to USB or Wi-Fi risk
With the development of the Internet of Things, more and more devices can be connected to the Internet, but it also leads to the entrance of hacker attacks Increasingly, even ransomware, which used to target personal computers, has also started the idea of a digital SLR storing people’s favorite photos.
Israeli security company Check Point released a report at the DEF CON hacker conference held in Las Vegas on the 11th, pointing out that digital SLR cameras may be hacked when they are connected to USB or Wi-Fi risk.

The researchers selected the latest Canon EOS 80D for testing, this camera supports both USB and Wi-Fi connection methods. Researchers found that since the common image transfer protocols of major cameras support various commands and do not require encryption or authentication, hackers can use this to implant malware into cameras. For example, they can easily encrypt EOS via Wi-Fi. Photos on SD card on 80D.
However, EOS 80D users don’t have to worry, Check Point has notified Canon of the vulnerability at the end of March, and Canon began to release patches in various regions on July 30.
More than EOS 80D, Check Point stated that most SLRs with Wi-Fi capabilities today are likely to face similar Threats, as long as the hacker and the target camera are on the same network, they can quietly install the ransomware to the target camera, thereby encrypting all pictures and displaying the ransom request.
“Any smart device, including DSLRs, is vulnerable to attack,” Check Point security researcher Eyal Itkin said at the conference. “The camera is no longer just connected via USB, but connected to Wi -Fi network and its surrounding environment, which makes them more vulnerable to threats, because attackers can implant ransomware through the camera or the computer connected to it. These photos may eventually be seized and released after the user pays the ransom.”
The reason why SLRs have become the target of hackers is well understood. After all, SLR cameras usually store a large number of private or precious photos, and users will not give up easily, and most people who own SLRs also have the financial strength to pay the ransom.
“Price, sensitive content, and a wide range of consumers make cameras a lucrative target for attackers,” the report reads.
As for how to avoid being recruited, the researchers gave three suggestions:
Update the camera firmware in time;
Turn off the camera’s Wi-Fi when unnecessary -Fi function
Try to avoid using Wi-Fi in public places.
In fact, not only cameras, but in the era of Internet of Everything, people have similar concerns about smart devices. Among them, the safety of Internet cars has attracted much attention.
Recently, scientists from Georgia Institute of Technology and Multiscale Systems conducted a simulation experiment that showed that a large number of Internet cars on the road at the same time may cause greater traffic safety hazards, because a loophole can affect millions of cars. This means that once a hacker launches an attack, it can cause traffic paralysis or even a large-scale accident, which is much more serious than computer or camera extortion. Jamie Court, chairman of the American Consumer Watchdog Organization, even called hacker attacks on Internet cars “the largest in existence. National security threats”.
