 Understanding SMS Hijacking

SMS hijacking, often referred to as SIM swapping or SMS interception, is a technique used by cybercriminals to gain unauthorized access to a victim's phone-based services. By exploiting vulnerabilities in telecom systems or human error, attackers redirect SMS messages, often used for two-factor authentication (2FA), to devices they control. This breach allows them to access bank accounts, email, and other sensitive platforms.

The sale of 【短信劫持数据】私人出售 on illicit marketplaces highlights how widespread and accessible this crime has become. Sellers often promise access to intercepted SMS messages, allowing buyers to bypass security protocols with ease.

 How Cybercriminals Hijack SMS Data

To understand the severity of 【短信劫持数据】私人出售, we must first explore how SMS hijacking works. The following methods are commonly employed:

1. SIM Swapping:

   - Attackers use social engineering to trick telecom providers into transferring a victim’s phone number to a new SIM card under their control.

   - Once the SIM swap is complete, all incoming calls and SMS messages are redirected to the attacker.

2. SS7 Exploitation:

   - Signaling System No. 7 (SS7) is a protocol used by telecom networks for routing calls and SMS messages.

   - Hackers exploit vulnerabilities in SS7 to intercept messages or reroute them without the victim's knowledge.

3. Malware and Phishing:

   - Attackers deploy malware on mobile devices to gain access to SMS messages.

   - Phishing campaigns trick users into providing access to authentication codes or personal information.

These techniques allow cybercriminals to intercept 2FA codes, enabling unauthorized access to accounts.

 The Marketplace for Stolen Data

The proliferation of 【短信劫持数据】私人出售 showcases how organized cybercrime has become. Sellers advertise these services on forums and dark web marketplaces, with promises of high success rates and quick delivery. The price for SMS hijacking services varies, depending on factors such as:

- The target's location and telecom provider.

- The number of intercepted messages or authentication codes required.

- The complexity of the security measures in place.

Buyers typically use cryptocurrencies to maintain anonymity, further complicating efforts to track and dismantle these operations.
