Hackers are able to use image steganography techniques to conduct malicious activity and ultimately compromise enterprise networks. Steganography is the practice of using hidden writing techniques to secretly pass information embedded within images. This technique has been around for hundreds of years ‘ most notably, it was used by Leonardo da Vinci, who embedded secret messages into his paintings. To combat these types of threats, enterprises will need to prioritize and adopt strategies that focus on the zero-day threats targeting the enterprise. The tools used for these attacks are not even considered hacking tools.
