New accounts
Installing new programs

Explanation: New user accounts are often created by attackers to maintain access, and unauthorized programs (malware, backdoors, tools) are commonly installed to enable persistent control or further changes. Opening new ports can also be a sign but the two strongest direct indicators of unauthorized changes are new accounts and new software.
