An attacker intercepts the following ciphertext $($encoded in hexadecimal$)$:

$94$f$043$aa$844$f$715$c$9$a$4347$a$48234$b$48$d $5956$caa$4$da$7$b$39$a$369$f$5$d$1$e$1$ccd$28232$

The attacker knows that the plaintext corresponds to the ASCII encoding of the message "A Alice $$10,000."($excluding the quotation marks$).$

The attacker also knows that CBC encryption was used with a random IV and AES as the underlying block cipher.

Show that the attacker can change the ciphertext so that it decrypts to "A Alice $$90,000.".$

What is the resulting ciphertext $($encoded in hexadecimal$)?$

This demonstrates that CBC does not provide integrity.
