WebSep 15, 2024 · Attacks that used steganography techniques Various types of threat actors, from crooks to cyberespionage groups, have used steganography to conceal information. WebMay 1, 2024 · For example: Bob and Alice agree on two numbers, a large prime, p = 29, and base g = 5 Now Bob picks a secret number, x (x = 4) and does the following: X = g^x % p (in this case % indicates the remainder. For example 3%2 is 3/2, where the remainder is 1). X = 5 ^4 % 29 = 625 % 29 = 16

WebHowever, there are ways to bypass this. A real example of this attack vector was found by one of our Synack researchers (sensitive information redacted). ... This is a very clear and simple example of a Cryptographic Failure, as these credentials should have been encrypted or stored in a key vault, instead of being hard-coded into the source code. WebDescription. Standard pseudo-random number generators cannot withstand cryptographic attacks. Insecure randomness errors occur when a function that can produce predictable values is used as a source of randomness in security-sensitive context. Computers are deterministic machines, and as such are unable to produce true randomness.
