The underground world of cybercrime is a vast and shadowy network where data breaches and stolen information fuel illicit trade. Among the many types of data being traded, 【短信劫持数据】 has emerged as one of the most sought-after commodities. This article delves into the mechanisms of this underground trade, the pricing of such data, and the implications for individuals and organizations.

What is 【短信劫持数据】?

In simple terms, 【短信劫持数据】 refers to intercepted or stolen SMS communications. SMS hijacking is a form of cyberattack where an attacker gains unauthorized access to an individual's text messages. This data can be used for a variety of malicious purposes, such as bypassing two-factor authentication (2FA), stealing sensitive information, or carrying out phishing schemes.

SMS messages are often underestimated in terms of security. However, many services, including banking and online accounts, rely on SMS-based 2FA. This makes text messages a prime target for cybercriminals who seek to exploit them for financial gain.

Why Is 【短信劫持数据】 Valuable?

There are several reasons why 【短信劫持数据】 commands a high price on the black market:

1. Access to Personal Accounts
        SMS-based 2FA codes are a key to unlocking personal accounts. By hijacking      SMS messages, attackers can gain access to bank accounts, social media,      and email accounts.

2. Identity Theft
        Intercepted messages often contain sensitive personal information, such as      passwords, addresses, and account details. Cybercriminals use this data to      commit identity theft, apply for loans, or make fraudulent purchases.

3. Corporate Espionage
        In some cases, corporate executives and employees are targeted for their      SMS communications. Hackers use this data to gain insights into business      strategies, trade secrets, and confidential information.

4. Monetary Gain Through Ransom
        Some attackers use stolen SMS data to blackmail victims, demanding ransom      payments in exchange for not exposing sensitive information.

How Cybercriminals Obtain 【短信劫持数据】?

The methods used to steal SMS messages are sophisticated and constantly evolving. Some of the most common techniques include:

• SIM Swapping
       This involves tricking a mobile service provider into transferring a      victim's phone number to a new SIM card controlled by the attacker. Once      this is done, the attacker can intercept all SMS messages intended for the      victim.

• Phishing and Social      Engineering
       Attackers often use phishing emails or messages to trick victims into      providing access to their devices or accounts. Once they gain control,      they can intercept SMS communications.

• Malware
       Malware installed on a victim's device can grant attackers access to SMS      messages and other sensitive data. This often occurs through malicious      apps or software.

• SS7 Exploits
       The Signaling System No. 7 (SS7) protocol, used by telecom providers to      route messages, has vulnerabilities that hackers exploit to intercept SMS      communications.

Black Market Pricing of 【短信劫持数据】

On the dark web, the price of 【短信劫持数据】 varies based on several factors:

1. Type of Data

• Basic SMS logs with minimal       sensitive information are less valuable, typically ranging from $50 to       $200 per account.

• SMS data containing financial       or banking information can fetch between $500 and $1,000 per account.

2. Target Demographics

• Data from high-income       individuals or corporate executives is priced significantly higher, often       exceeding $2,000 per set of credentials.

• Information tied to       government or law enforcement personnel can cost up to $10,000 due to the       higher risks involved.

3. Source of the Data

• Freshly obtained SMS data is       more expensive, as it is more likely to be actionable.

• Older or widely circulated       data sells for less, often at bulk rates as low as $10 per account.

4. Customization

• Tailored attacks, where       specific individuals or organizations are targeted, come with premium       pricing. Such services can cost anywhere from $5,000 to $20,000,       depending on the complexity of the attack.

How to Protect Yourself from SMS Hijacking

While the risks are significant, there are steps individuals and organizations can take to minimize the likelihood of falling victim to SMS hijacking:

1. Use Alternative 2FA Methods
        Instead of SMS-based authentication, opt for more secure methods like      authentication apps (e.g., Google Authenticator) or hardware tokens (e.g.,      YubiKey).

2. Secure Your SIM Card

• Add a PIN code to your SIM       card for an additional layer of security.

• Notify your mobile carrier to       enable protections against unauthorized SIM swaps.

3. Be Wary of Phishing Attempts
        Avoid clicking on suspicious links or providing sensitive information in      response to unsolicited messages.

4. Monitor Account Activity
        Regularly check your accounts for unauthorized transactions or login      attempts.

5. Invest in Security Tools
        Use antivirus software and enable device encryption to protect your data.
