Jizô AI is a threat detection product by Sesame IT focused on identifying steganography-based attacks used by cybercriminals. Steganography is the practice of concealing secret data within ordinary-looking digital media or network communications, making it inherently difficult to detect through conventional security tools. The product addresses a range of steganography techniques across multiple media types: - Image-based steganography (e.g., LSB/least significant bit manipulation, JPEG DCT, PNG chunk modification) - Video-based steganography (e.g., exploitation of compression standards like H.264) - Audio-based steganography (e.g., amplitude/frequency manipulation of high-frequency signals) - Text document steganography (e.g., hidden notes, whitespace encoding in Word files) - Network protocol steganography (e.g., manipulation of IP header fields, TCP flags, DNS TXT fields, timing-based covert channels) Jizô AI applies artificial intelligence to detect these concealment methods, which are used by threat actors for covert communications, data exfiltration, and command-and-control operations. The product targets the detection of both injection-based and substitution-based steganography across digital environments. The page describes the technical underpinnings of steganography and positions Jizô AI as a detection solution for these techniques within a cybersecurity context.
