Unwanted exposure of restricted account details
Excess data consumption that reduces resource availability
Unapproved modification of system commands that alters valid output
Forged identity usage that mimics valid user credentials
Altering system files to produce incorrect output demonstrates unauthorized modification. The other options describe different forms of attacks, such as forging identities, overwhelming resources, or extracting sensitive data.
