More questions about Cybersecurity

These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

1. 1 Easy

   What malware pretends to be a legitimate program so users install it?

   Answer: Trojan horse

   Why: Unlike worms that spread automatically across networks, a Trojan horse cannot self-replicate and relies entirely on user deception to execute.

2. 2 Medium

   What is added to a password before hashing to defeat rainbow tables?

   Answer: cryptographic salt

   Why: Unlike a secret pepper stored outside the database, a salt is unique per user and saved openly beside the hash, so identical passwords hash differently.

3. 3 Hard

   Which physical machines were destroyed by the Stuxnet worm in Iran?

   Answer: nuclear centrifuges

   Why: Stuxnet pushed the centrifuge drives to 1410 Hz, then down to 2 Hz, while replaying recorded normal readings so the control room saw nothing.

4. 4 Easy

   In cybersecurity simulations, what is the primary role of the Blue Team?

   Answer: Defending against active threats

   Why: Blue Team defends, Red Team attacks, and a neutral White Team referees the drill, setting the rules and scoring both sides.

5. 5 Medium

   What attack installs malware just by visiting a hacked webpage?

   Answer: Drive-by download

   Why: Exploit kits behind drive-by downloads first scan your browser and plugins, then strike only if they find an unpatched flaw.

6. 6 Hard

   In security jargon, what is 'rubber-hose cryptanalysis'?

   Answer: extracting secret keys through physical coercion

   Why: The term comes from Usenet's sci.crypt, where someone joked it takes a surprisingly short time and costs almost no computation.
