#GREEK WORD FOR HIDE CODE#

These tools are extremely easy to use-some are even drag and drop-with no code necessary. However, image steganography toolkits are widely available, with hundreds of free apps on the market. One downside of steganography is that its limited delivery mechanism translates into low frequency, and therefore cannot achieve the high volumes that cybercriminals traditionally prefer. Like all malware, image steganography can be used to hide the payload within the code itself or the code can call additional code or executables associated with attacks. The color value differences between altered and unaltered pixels are subtle enough that human eyesight cannot detect them, and it would be very time consuming for machines to scan every image for hidden data, especially when the threat is unknown. For example, a standard JPEG photo contains several megabytes of pixel data, allowing an attacker to alter several of the pixels to embed malicious code. It is not difficult for a hacker to conceal malicious code in digital content. How can malware hide in image steganography? In fact, in 2017, security researchers reported a 600% increase in image steganography attacks. Hackers may utilize legitimate services, such as free image hosting services, to ensure their malware is spread to as many users as possible. Cybercriminals have harnessed this effective method for hiding information in plain sight, both because cybersecurity experts may overlook this old trick and because it is easy to convince users to open images without prompting suspicion. Image steganography refers to the practice of hiding code within an innocent-looking image. One old-school threat that has reappeared in a more sophisticated form is image steganography. Cybersecurity demands constant vigilance hackers are constantly expanding their arsenal of threats and are even revitalizing old attack methods.
