Which risk increases during lossless data compression when entropy decreases toward zero thanks to carefully crafted weighting functions?

A)Catastrophic heap overflow event
B)Increased parallel processing efficiency
C)Vulnerability to dictionary attacks
D)Diminished data caching effectiveness

💡 Explanation

Reduced entropy means predictable patterns, because information gain from each bit is lower. Entropy-encoded compression now depends on publicly calculable functions; therefore, dictionary attacks work, rather than brute-force ones, because keyspaces are vastly smaller.
