Which of the following is an attack vector that can cause extensive physical damage to a datacenter without physical access?

Question

Options

• ACCTV system access
• BDial-up access
• CChanging environmental controls
• DPing of death

• A
  2% (1)
• B
  10% (4)
• C
  81% (34)
• D
  7% (3)

Explanation

Changing environmental controls (C) - such as remotely manipulating HVAC, cooling systems, temperature thresholds, or humidity settings - can raise temperatures to levels that physically destroy servers, storage arrays, and networking hardware without the attacker ever entering the building. Modern building management systems (BMS) and industrial control systems are often network-accessible, making this a realistic remote attack path. CCTV system access (A) provides surveillance capability but does not cause physical damage. Dial-up access (B) is simply a remote connectivity method; gaining access via dial-up does not by itself damage anything. Ping of Death (D) is a legacy network-layer attack that can crash or reboot systems but does not cause lasting physical hardware damage.
