Exploit chaininginvolves combining multiple lower-severity vulnerabilities toescalate privileges or gain persistencein a network. The attacker:
* Combines Multiple Exploits:Uses interconnected vulnerabilities that, individually, seem low-risk but together form a critical threat.
* Privilege Escalation:Gains elevated access by chaining exploits, often bypassing security measures.
* Persistence Mechanism:Once privilege is gained, attackers establish long-term control.
* Advanced Attacks:Typically seen in advanced persistent threats (APTs) where the attacker meticulously combines weaknesses.
Other options analysis:
* B. Brute force attack:Involves password guessing, not chaining vulnerabilities.
* C. Cross-site scripting:Focuses on injecting malicious scripts, unrelated to privilege escalation.
* D. Rogue wireless access points:Involves unauthorized devices, not exploit chaining.
