Go to Start > Run (or directly to Search on newer Windows versions), type regedit and click OK. 3. IMPACT: This attack (CVE-2016-2183), called "Sweet32", allows an attacker to extract the plaintext of the repetitive content of a 3DES encryption stream.As 3DES block size is only 64-bit, it is possible to get a collision in the encrypted traffic, in case enough repetitive data was sent through the connection which might allow an attacker to guess the cleartext. What are the steps on resolving this? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.
