Here is the full paper:

Please note that this paper is quite old, and RC7 has not been widely used or considered secure for many years. Modern cryptography has moved on to more secure and widely accepted algorithms, such as AES. rc7 cracked

You're referring to the alleged cracking of the RC7 block cipher! Here is the full paper: Please note that

Here's a brief summary:

After conducting a thorough search, I found a paper that discusses the cryptanalysis of RC7. Here it is: which can recover the secret key.

The authors conclude that RC7 is not as secure as previously thought and that a large number of rounds can be distinguished from a random permutation. They also show that a practical attack on RC7 is feasible, which can recover the secret key.
