In 2016, one of the leading network device manufacturers, Juniper Networks, found that some of its firewalls had firmware that contained backdoors installed by hackers. The backdoors enabled hackers to decrypt traffic flowing through the firewalls. It clearly meant that the hackers wanted to infiltrate organizations that had bought firewalls from the company. Juniper Networks said that such a hack could only have been actualized by a government agency with enough resources to handle traffic flowing in and out of many networks. The National Security Agency (NSA) was put in the spotlight since the backdoor had similarities to another one that was also attributed to the agency. Although it is unclear who was actually responsible for the backdoor, the incident brings up a big threat.

Hackers seem to be adopting the use of backdoors. This is being actualized by compromising one of the companies in the supply chain that delivers cyber-related products to consumers. In the discussed incident, the backdoor was planted at the manufacturer's premises, and therefore any organization that bought a firewall from them was infiltrated by the hacker. There have been other incidents where backdoors have been delivered embedded in a software. Companies selling legitimate software on their websites have also become targets for hackers. Hackers have been inserting codes to create backdoors into legit software in a manner that the backdoor will be harder to find. It is one of the adaptations that hackers are having to take due to the evolution of cybersecurity products. Since these types of backdoor are hard to find, it is expected that they will be extensively used by hackers in the near future.
