OPSEC in carding

[chushpan]

OPSEC (Operational Security) is a set of practices and principles aimed at protecting sensitive information and preventing data leaks that could reveal the identity or actions of an attacker. In the context of carding, OPSEC is used to minimize the risks of detection, arrest, or blocking of operations. However, it is important to understand that using OPSEC for illegal activities such as carding is a criminal offense.

In this article, we will look at how OPSEC is applied in carding, what methods are used to ensure security, and why these methods do not protect against justice.

1. What is OPSEC?​

OPSEC is a strategic approach to information security that focuses on the following principles:

• Identification of critical information.
• Analysis of threats and vulnerabilities.
• Application of measures to minimize risks.

In carding, OPSEC helps attackers:

• Hide your identity.
• Protect card data and other stolen assets.
• Avoid detection by banks, law enforcement and other organizations.

2. Basic principles of OPSEC in carding​

a. Minimizing digital footprint​

• Description: Attackers try to leave as few traces as possible on the Internet.
• Methods:
  • Using anonymous accounts.
  • Avoiding public forums where you could be identified.
  • Remove metadata from files (e.g. EXIF data from images).

b. Separation of personal and operational life​

• Description: Fraudsters separate their personal actions and carding operations.
• Methods:
  • Use of individual devices for illegal activities.
  • Creating fake profiles that are not associated with a real person.
  • Avoid using your real data (such as your phone number or email).

c. Communications protection​

• Description: Ensuring safety when communicating with accomplices.
• Methods:
  • Using encrypted messengers (for example, Signal, Telegram with secret chats).
  • Avoid discussing details of operations in open channels.

d. Using anonymous tools​

• Description: Using technology to hide identity and location.
• Methods:
  • Using Tor or I2P to access the darknet.
  • Using VPN to mask your IP address.
  • Using anonymous email services (eg ProtonMail, Temp Mail).

e. Control of financial flows​

• Description: Concealment of sources and directions of funds.
• Methods:
  • Converting stolen funds into cryptocurrency (e.g. Bitcoin, Monero).
  • Using mixers to "mix" cryptocurrencies.
  • Transferring money through multiple accounts to make tracking difficult.

f. Using "drops" and mules​

• Description: Transferring responsibility for receiving goods or money to third parties.
• Methods:
  • Drops are fake addresses for delivery of goods.
  • Mules are individuals who provide their bank accounts for the transfer of funds.

3. How do carders use OPSEC in carding?​

Example 1: Getting map data​

• The carder uses a skimming device on the ATM.
• To analyze the data, he uses a separate laptop that is never connected to the Internet.
• All communications with accomplices are conducted through encrypted messengers.

Example 2: Purchase of goods​

• The scammer creates a fake account on the Cardable 2D website.
• A cloned card is used for payment.
• The goods are delivered to the drop address, not to the real address of the scammer.

Example 3: Money Laundering​

• The stolen funds are transferred to a crypto exchange through an anonymous account.
• The cryptocurrency is "mixed" through a mixer and then withdrawn to another wallet.
• The money is cashed out through a money mule.

4. Why does OPSEC not guarantee security?​

Despite using OPSEC, attackers often make mistakes that lead to their capture. Here are the main reasons:

a. Human factor​

• Fraudsters may accidentally use their real data (for example, email or phone number).
• Accomplices may be less careful and give away information.

b. Technical vulnerabilities​

• VPN provider logs may be provided to law enforcement agencies.
• Blockchain analysis allows you to track cryptocurrency transactions.

c. Law enforcement investigations​

• Law enforcement agencies are actively monitoring the darknet and forums.
• Using honeypots to identify fraudsters.

d. Errors in operations​

• Fraudsters may not notice that their actions are being tracked.
• Some transactions may be too obvious (for example, large purchases made with stolen cards).

5. How do law enforcement counter OPSEC?​

a. Digital Footprint Analysis​

• Research IP addresses, even if they are hidden through Tor or VPN.
• Analyze metadata from files and messages.

b. Use of artificial intelligence​

• Machine learning algorithms identify suspicious patterns in transactions.
• Analysis of user behavior on the network.

c. Working with informants​

• Accomplices or mules may cooperate with law enforcement.
• Drops can be used to identify organizers.

d. International cooperation​

• Sharing data between countries to identify fraudsters.
• Closing of darknet sites and arrest of administrators.

6. Conclusion​

While OPSEC can help attackers temporarily hide their actions, it does not guarantee complete anonymity. Modern technology and law enforcement efforts make carding an increasingly risky activity. Any attempt to use OPSEC for illegal activities is against the law and can lead to serious consequences, including criminal liability.
