APT is a type of cyber attack that is carried out by a skilled hacker or group of hackers with the intention of gaining access to a network or system and remaining undetected for a long period of time. APTs are often used to steal sensitive data or to sabotage systems. There is no single definition of an APT, but most experts agree that they are typically more sophisticated and dangerous than other types of cyber attacks. They are often carried out by nation-state actors or well-funded criminal groups, and can be very difficult to detect and defend against.
Some of the most common tactics used by APT hackers include:
Spear phishing:
Sending targeted emails that appear to be from a trusted source in order to trick recipients into clicking on malicious links or opening infected attachments.
Social engineering:
Manipulating people into revealing sensitive information or performing actions that allow the hacker to gain access to a network or system.
Malware:
Software that is designed to exploit vulnerabilities in systems or networks, often by installing itself without the user’s knowledge.
Backdoors:
Programs or techniques that allow a hacker to access a system or network undetected
Watering hole attacks:
Targeting websites that are frequented by a particular group of people (e.g. employees of a particular company) with malware or phishing attacks in order to gain access to their systems.
Botnets:
Networks of infected computers that are used to carry out large-scale cyber attacks.
The best way to protect against APTs is to use a combination of strong security measures, such as firewalls, antivirus software, and intrusion detection systems, and to keep your software and systems up to date. Employees should also be trained to recognize phishing and social engineering attacks, and to never open unsolicited emails or attachments.
