Case Study Quiz: Security Lessons from Popular Online Games Quiz

Explore essential cyber security lessons derived from real-world incidents and practices in popular online multiplayer games. This quiz helps players and developers recognize and prevent common security threats unique to online gaming environments.

1. Credential Stuffing Threats in Online Games

   Why are reused passwords particularly risky in online games, as seen in several high-profile security breaches?

   1. Because attackers can use credential stuffing attacks to access multiple accounts with stolen password lists.
   2. Because reused passwords slow down account recovery processes.
   3. Because reused passwords help increase game server latency.
   4. Because game servers automatically force password resets after every login.

   Explanation: Reusing passwords is risky since attackers can use stolen credentials from other sites to access gaming accounts, a method known as credential stuffing. The second option is inaccurate because servers do not force password resets after every login. The third option is incorrect; password reuse does not significantly impact account recovery times. The last option, relating to server latency, has no direct link to password reuse. Using unique and strong passwords is crucial for account safety.

2. Phishing Scenarios in Virtual Marketplaces

   In an online game with a trading marketplace, what is a common security risk of clicking unknown trade links shared by other players?

   1. Unknown links optimize game performance automatically.
   2. The links always grant free premium currency.
   3. The links might lead to phishing websites that steal account credentials.
   4. The links are harmless as long as they come from players you met in-game.

   Explanation: Phishing links can trick players into revealing login details or other sensitive information, leading to account theft. Expecting free premium currency is often the bait but rarely the outcome. Links do not improve game performance; this option is misleading. Trusting links solely because they come from acquaintances in-game is unsafe, as compromised accounts or imposters can also share harmful links.

3. Two-Factor Authentication Advantages

   Which primary security benefit does enabling two-factor authentication (2FA) provide for online game accounts?

   1. It allows accounts to bypass normal login requirements.
   2. It prevents all forms of in-game cheating.
   3. It guarantees your account will never be hacked.
   4. It requires a second form of verification, making unauthorized logins much harder.

   Explanation: Two-factor authentication adds an extra step, such as a code sent to a device, making it much more difficult for attackers to gain access without authorization. While 2FA greatly increases security, it does not guarantee absolute protection from all attacks. It does not address game cheating, which involves separate mechanisms. Bypassing normal logins would diminish, not enhance, security.

4. DDoS Attack Consequences in Multiplayer Games

   When a distributed denial-of-service (DDoS) attack targets an online multiplayer game server, what is a likely result for players?

   1. Players may experience severe lag or become disconnected from the game.
   2. Players can suddenly control other users’ characters.
   3. All player account data is instantly deleted.
   4. Players immediately receive bonus items as compensation.

   Explanation: A DDoS attack overloads game servers with traffic, causing lag or disconnections for legitimate players. It does not directly delete account data, contrary to option two. Compensation such as bonus items might come later, but it is not an immediate or automatic outcome. Gaining control of other users’ characters is unrelated to the effects of a DDoS attack.

5. Account Recovery Pitfalls

   What is a common security risk when using weak or easily guessed answers to account recovery questions in online games?

   1. Attackers can reset the account’s password by guessing or discovering the answers.
   2. Players get locked out of their account after one wrong answer.
   3. Game achievements are automatically reset.
   4. Matchmaking ratings are instantly decreased.

   Explanation: Weak recovery answers make it easier for attackers to gain control of accounts by exploiting the password reset process. Game achievements and matchmaking ratings are not directly affected by how you answer recovery questions. Players are generally not locked out immediately after one wrong answer; systems typically allow multiple attempts. Choosing strong, unique answers is important for security.
