In the present article, we discuss the decoding of Gabidulin and related codes from a cryptographic perspective and we observe that these codes can be decoded with the single knowledge of a generator matrix. Then, we extend and revisit Gibson's and Overbeck's attacks on the generalised GPT encryption scheme (instantiated with Gabidulin codes) for various ranks of the distortion matrix and apply our attack to the case of an instantiation with twisted Gabidulin codes.
