What are the characteristics of apt attacks?

The characteristics of apt attacks are: 1. Highly targeted; 2. Tightly organized; 3. Long duration; 4. High concealment; 5. Indirect attacks. The targets of apt attacks are clear, and most of them are targets with rich data and intellectual property rights.

APT attacks have five distinctive characteristics that are different from traditional network attacks: highly targeted, well-organized, long duration, high concealment and indirect attacks .

1. Highly targeted

APT attacks have clear targets, and most of them have rich data/knowledge For the purpose of property rights, the data obtained are usually trade secrets, national security data, intellectual property, etc.

Compared with traditional attacks that steal personal information, APT attacks only focus on pre-specified targets. All attack methods only target specific targets and specific systems, and are highly targeted.

2. Tight organization

A successful APT attack can bring huge commercial benefits, so attackers usually exist in the form of organizations, with skilled hackers forming a group, dividing labor and cooperating, and carrying out long-term premeditation and planning. attack. They have sufficient financial and technical resources, and have the conditions and capabilities to focus on APT research for a long time.

3. Long duration

APT attacks are highly persistent. After long-term preparation and planning, attackers usually lurk in the target network for months or even years. Penetration, constantly improving attack paths and methods, and launching continuous attacks, such as zero-day vulnerability attacks.

4. High concealment

According to the characteristics of the target, APT attacks can bypass the defense system of the target network and steal data or cause damage in an extremely concealed manner. In the information collection stage, attackers often use search engines, advanced crawlers and data leaks to continuously penetrate, making it difficult for the attacker to detect; in the attack stage, based on the results of sniffing the target, they design and develop highly targeted Trojans, etc. Malware, bypassing target network defense systems and conducting covert attacks.

5. Indirect attack

APT attacks are different from the direct attack methods of traditional network attacks. They usually use third-party websites or servers as springboards to deploy malicious programs or Trojans to penetrate the target. Malicious programs or Trojans lurk in the target network and can be remotely controlled by the attacker or triggered by the attacker unintentionally.
