Using your actual name, email address, and phone number on social media can lead to identity theft, a threat that can be strategically analyzed through the principles of Sun Tzu’s “The Art of War.” Here’s a detailed breakdown of the risks and how they correlate with Sun Tzu’s strategies.

1. Exposure to Phishing Attacks

• Risk: Sharing your email address publicly can expose you to phishing attacks.
• How it Happens: Cybercriminals send deceptive emails that appear legitimate, tricking you into revealing sensitive information or clicking on malicious links.
• Sun Tzu’s Principle: “All warfare is based on deception.” (Chapter 1: Laying Plans)
  • Application: Phishing relies on deception, much like Sun Tzu’s strategies. By using your real email, you make it easier for attackers to craft convincing, deceptive messages.

2. Social Engineering Attacks

• Risk: Using your real name and phone number can facilitate social engineering attacks.
• How it Happens: Attackers manipulate you or your contacts into revealing more personal information or performing actions that compromise security.
• Sun Tzu’s Principle: “If you know the enemy and know yourself, you need not fear the result of a hundred battles.” (Chapter 3: Attack by Stratagem)
  • Application: Social engineers gather as much information about you (the enemy) as possible. By using your real information, you provide attackers with valuable knowledge.

3. Credential Stuffing

• Risk: Your email address can be used in credential stuffing attacks.
• How it Happens: Attackers use automated tools to test your email and common passwords on various websites, potentially gaining access to your accounts.
• Sun Tzu’s Principle: “Attack him where he is unprepared, appear where you are not expected.” (Chapter 1: Laying Plans)
  • Application: Attackers exploit the unpreparedness of individuals using weak or reused passwords, targeting them unexpectedly.

4. Information Aggregation

• Risk: Sharing your name, email, and phone number allows attackers to aggregate information.
• How it Happens: Cybercriminals collect data from various sources, creating a comprehensive profile to answer security questions or commit fraud.
• Sun Tzu’s Principle: “The whole secret lies in confusing the enemy, so that he cannot fathom our real intent.” (Chapter 5: Energy)
  • Application: By using multiple sources to gather data, attackers create confusion and obfuscate their true intentions until it’s too late.

5. Impersonation and Fraud

• Risk: Attackers can impersonate you with your real name, email, and phone number.
• How it Happens: Criminals create fake profiles, apply for credit, or make purchases in your name, causing financial and reputational damage.
• Sun Tzu’s Principle: “Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.” (Chapter 7: Maneuvering)
  • Application: Attackers use your personal information to create false identities and strike swiftly and unexpectedly.

6. Account Takeovers

• Risk: Public information can lead to account takeovers.
• How it Happens: Attackers use gathered information to guess or reset passwords, gaining unauthorized access to your accounts.
• Sun Tzu’s Principle: “If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant.” (Chapter 1: Laying Plans)
  • Application: Attackers exploit weak security measures, often assuming users’ overconfidence in their security.

7. Physical Security Threats

• Risk: Sharing personal contact information can pose physical security risks.
• How it Happens: Cyberstalkers or criminals use your phone number to track your location or harass you.
• Sun Tzu’s Principle: “Know the enemy and know yourself; in a hundred battles, you will never be in peril.” (Chapter 3: Attack by Stratagem)
  • Application: Physical threats arise from attackers knowing your personal details, which they can use against you.

8. Privacy Invasion

• Risk: Your privacy can be severely compromised.
• How it Happens: Publicly available personal information is used for unsolicited marketing, spam, or invasive data mining.
• Sun Tzu’s Principle: “When you surround an army, leave an outlet free. Do not press a desperate foe too hard.” (Chapter 7: Maneuvering)
  • Application: Overexposure of personal information leaves no outlet for privacy, leading to desperate situations where privacy is invaded aggressively.

Preventive Measures and Sun Tzu’s Insights:

1. Limit Personal Information Sharing: Avoid sharing full name, email address, and phone number on social media.
   • Sun Tzu’s Insight: “Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected.” (Chapter 6: Weak Points and Strong)
     • Application: By not revealing too much, you make it harder for attackers to target you.
2. Use Privacy Settings: Adjust settings to control who can see your information.
   • Sun Tzu’s Insight: “He who is prudent and lies in wait for an enemy who is not, will be victorious.” (Chapter 1: Laying Plans)
     • Application: Be prudent with your privacy settings to protect against unprepared attackers.
3. Use Separate Contact Information: Use separate email addresses and phone numbers for social media.
   • Sun Tzu’s Insight: “In war, the way is to avoid what is strong and to strike at what is weak.” (Chapter 6: Weak Points and Strong)
     • Application: By compartmentalizing your contact information, you weaken potential attack points.
4. Enable Two-Factor Authentication (2FA): Enhance account security with 2FA.
   • Sun Tzu’s Insight: “Opportunities multiply as they are seized.” (Chapter 5: Energy)
     • Application: Use every available security measure to multiply your defense opportunities.
5. Monitor Your Accounts: Regularly check for suspicious activity.
   • Sun Tzu’s Insight: “Ponder and deliberate before you make a move.” (Chapter 1: Laying Plans)
     • Application: Regular monitoring allows you to deliberate and act swiftly against threats.

Conclusion

Publicly sharing your actual name, email address, and phone number on social media increases the risk of identity theft through various methods, including phishing, social engineering, and credential stuffing. By applying Sun Tzu’s principles from “The Art of War,” we can better understand the strategies used by attackers and implement effective measures to protect our identities and personal information.

This is just a fun little toy that happened while working on MySQL Automation.
The files used are first_names.txt, last_names.txt and domains.txt.
Reading random lines from the files in order creates the “Fake Email Address” and using [array_rand($variable)]; each email address is somewhat unique as I’m only using 80,000 names (give or take a few hundred).

All Files: fake-email-generator.zip

#!/bin/bash
$first_names = 'first_names.txt';
$last_names = 'last_names.txt';
$dom = 'domains.txt';

    $firstname = file($first_names);
    $fdata = $firstname[array_rand($firstname)];
    $first = $fdata;

        $lastname = file($last_names);
        $ldata = $lastname[array_rand($lastname)];
        $last = $ldata;

    $comd = file($dom);
    $edata = $comd[array_rand($comd)];
    $com = $edata;

        $first = preg_replace('/\s+/', '', $first);
        $first = strtolower($first);
        $last = preg_replace('/\s+/', '', $last);
        $last = strtolower($last);
        $com = preg_replace('/\s+/', '', $com);

    echo $first."@".$last.$com;]
