Are you claiming that a random-bit-flipping attack such as targeted read disturb can cause corrupted data to be returned even through data scrambling, a first-level LDPC check and a final CRC check on the output?

From your paper: "We assume that the victim system runs a filesystem on top of MLC NAND flash-based SSD."

It seems very naive to be surprised that people would assume this is an attack on SSDs.
