> An observer of the produced random numbers can potentially deduce the next numbers from the first 1024 random numbers.

By definition, a cryptographically secure pseudorandom number generator cannot be predicted like that by a computationally bounded attacker.

Thus if any attacker could deduce the next number from /dev/random by observing the numbers before, the algorithms they adopt is fundamentally wrong, and nothing could the save the security in that case.
