1. What is fullz and how to use it?​

Definition:​

Fullz (full info) is a complete package of the victim's personal data, usually including:

• First and last name
• Date of birth
• Residential address
• Social Security Number (SSN)
• Bank card number and CVV
• Email and phone
• Sometimes passport data, driver's license

Educational use:​

• To analyze the quality of data leaks.
• For testing anti-fraud systems.
• To develop identity verification policies.
• To train cybersecurity professionals to recognize signs of identity theft.

Objective: To study how attackers use data combinations to commit fraud and how to protect against this at the system level.

2. How to access the victim's email and phone?​

Technical methods (theoretical):​

• Phishing attacks through fake login pages (eg Google, Yahoo).
• SIM-swapping: hacking a phone number through a telecom operator.
• Social engineering: calling support with fake data.
• Malware: programs that intercept SMS/calls or authorization data.
• Brute force and credential stuffing: using previously leaked passwords.

Protective measures:​

• Two-factor authentication (Totp, hardware keys).
• Checking account security.
• Blocking phone number changes without confirmation.

Objective: To analyze vulnerabilities in digital identity management, to teach users how to protect their accounts.

3. How to intercept OTP via bots?​

What is OTP?​

OTP (One-Time Password) is a temporary code used for two-factor authentication.

Interception methods (theoretical):​

• SMS repeaters (via malware on the device).
• Telegram bots that receive SMS via third-party API services.
• SIM cards with SMS redirection to a remote server.
• Webhook interceptors embedded in phishing pages.

Protective measures:​

• Opting out of SMS as a second factor.
• Using TOTP (Google Authenticator), U2F tokens.
• Monitor for unusual login attempts.

Objective: To study weaknesses in authentication, develop more secure MFA protocols.

4. How to link bank logs with Venmo/Zelle/Cash App?​

What are bank logs?​

Bank logs are user account data in online banking, including login, password, secret questions, etc.

Possible methods (theoretical):​

• Login to online banking → add link to Venmo/Zelle/Cash App.
• Transfer funds to these platforms after gaining access.
• Using automated scripts for mass log processing.

Protective measures:​

• Monitoring activity in online banking.
• Notifications about new devices/login locations.
• Two-factor authentication with push confirmation.

Objective: To study vulnerabilities in integration between financial services, to develop access restriction policies.

5. What data should match when working with logs?​

Critical data:​

• First and last name
• Date of birth
• Address
• Phone number
• Email
• Postal code
• Social Security Number (SSN)

If this data does not match what is stored in the bank or payment system, the system may block the transaction or request.

Objective: To study verification requirements in financial systems, to create models for verifying the authenticity of user data.

6. How to make ABA+RN transfers safely?​

What is ABA + RN?​

• ABA (American Bankers Association number) is a US routing number.
• RN (Routing Number) is the bank and branch identifier.

Safety (theoretical):​

• Use of counterfeit documents (e.g. checks) with real ABA/RN.
• Substitution of information in electronic transfer forms.
• Using "clean" accounts to withdraw funds.

Protective measures:​

• Checking the sender and recipient match.
• Monitoring suspicious transfers.
• Using modern technologies to detect counterfeits.

Objective: Analysis of vulnerabilities in banking systems, development of mechanisms to prevent fraudulent transfers.

7. How to cheat Plaid?​

What is Plaid?​

Plaid is a platform that provides access to bank account data via API to apps like Venmo, Robinhood, Cash App.

Possible methods of deception (theoretical):​

• Using fake accounts.
• Intercepting API requests and modifying data.
• Login phishing via cloned Plaid form.

Protective measures:​

• Using OAuth and token-based authentication.
• Monitoring for unusual activity.
• Traffic encryption and integrity checking.

Objective: Research of vulnerabilities in Open Banking, development of standards for secure data exchange.

8. How to create "live" accounts?​

What are "live" accounts?​

These are accounts that look real: have activity history, avatar, contacts, purchase history, etc.

Creation (theoretical):​

• Using leaked data (Fullz).
• Automation of behavior through bots (viewing products, likes, messages).
• Registration via proxy and browser masking.
• Using fake information, but with "live" behavior.

Protective measures:​

• Checking behavioral patterns.
• Monitoring registration from one IP.
• Using CAPTCHA and other anti-bot mechanisms.

Objective: Study of behavioral analytics, development of systems for detecting fake profiles.

9. What phishing pages are currently active?​

Modern types of phishing:​

• Clone phishing: exact copies of official pages.
• Spear phishing: personalized attacks.
• Content spoofing: changing the content of a page to allow data entry.
• MFA bypass phishing: pages that request MFA tokens.

Effective technologies:​

• Hosting on domains similar to the originals (exampIe.com instead of example.com).
• Using Let's Encrypt for SSL certificates.
• Direct data transfer via Telegram bots or webhooks.

Protective measures:​

• Teaching users to recognize phishing.
• Using DNS filtering and URL reputation.
• Detecting fake websites using machine learning.

Objective: Analysis of modern phishing techniques, development of early detection systems.

10. How to exit via crypto after using bank logs?​

How does cryptocurrency exit work:​

• Transfer money from a bank account to a wallet via P2P platforms.
• Using crypto exchanges with low KYC requirements.
• Laundering of funds through mixers and chain hopping.

Stages:​

1. Transfer from bank account to Cash App/Venmo.
2. Transfer to crypto exchange via P2P ads.
3. Transfer to an anonymous wallet.
4. Exchange for other cryptocurrencies.
5. Withdrawal to fiat via OTC exchanges or darknet.

Protective measures:​

• KYC/AML checks on exchanges.
• Monitoring transactions through blockchain analysis.
• Cooperation with law enforcement agencies.

Objective: Study the path from financial fraud to anonymous withdrawal of funds, development of blockchain transaction tracing technologies.

Conclusion:​

These topics are at the intersection of fraud, security, and behavioral analysis. Studying them is important for:

• Development of fraud detection systems.
• Conducting pentests and red tests.
• Training of cybersecurity specialists.
• Development of new authentication and authorization protocols.
