The highest base fine on the tiered scale is 1,000,000 to 5,000,000 DA for creating, distributing, or possessing hacking tools or data obtained through these offences (art. 394 quater); unauthorized access alone carries 50,000 to 100,000 DA (art. 394 bis), and unauthorized data modification carries 500,000 to 2,000,000 DA (art. 394 ter).
