What is Honeypot?

A Honeypot is a network-attached system used as a trap for cyber-attackers to detect and study the tricks and types of attacks used by hackers. It acts as a potential target on the internet and informs the defenders about any unauthorized attempt at the information system. Honeypots are mostly used by large companies and organizations involved in cybersecurity. It helps cybersecurity researchers learn about the different types of attacks used by attackers. It is suspected that even cybercriminals use these honeypots to decoy researchers and spread wrong information. The cost of a honeypot is generally high because it requires specialized skills and resources to implement a system such that it appears to provide an organization’s resources while still preventing attacks at the backend and access to any production system.

Types of Honeypot

Honeypots are classified based on their deployment and the involvement of the intruder, such as the purpose of deploying them, how they interact with the targets:

1. Based on their deployment, Honeypots are divided into

• Research honeypots: These are used by researchers to analyze hacker attacks and deploy different ways to prevent these attacks.
• Production honeypots: Production honeypots are deployed in production networks along with the server. These honeypots act as a frontend trap for the attackers, consisting of false information and giving time to the administrators to improve any vulnerability in the actual system.

3. Based on interaction, honeypots are classified into

• Low interaction honeypots: Low interaction honeypots gives very little insight and control to the hacker about the network. It simulates only the services that are frequently requested by the attackers. The main operating system is not involved in the low interaction systems and therefore it is less risky. They require very fewer resources and are easy to deploy. The only disadvantage of these honeypots lies in the fact that experienced hackers can easily identify these honeypots and can avoid it.
• Medium Interaction Honeypots: Medium interaction honeypots allows more activities to the hacker as compared to the low interaction honeypots. They can expect certain activities and are designed to give certain responses beyond what a low-interaction honeypot would give.
• High Interaction honeypots: A high interaction honeypot offers a large no. of services and activities to the hacker, therefore, wasting the time of the hackers and trying to get complete information about the hackers. These honeypots involve the real-time operating system and therefore are comparatively risky if a hacker identifies the honeypot. High interaction honeypots are also very costly and are complex to implement. But it provides us with extensively large information about hackers.

How do Honeypots Work?

The mechanism of honeypots involve detecting and monitoring the activity on them, diverting the attackers away from the critical systems, researching about the behavior of the attackers and warning the security teams o prepare for an attack and mitigate it at its earliest, the following steps are explained in details below:

• Detection and Monitoring: By analyzing the activity on honeypots, security teams gain insights into attack techniques, patterns, and vulnerabilities. They can identify new threats or zero-day exploits.
• Diversion: Honeypots divert attackers away from critical systems. Instead of compromising actual assets, cybercriminals waste time and resources on the decoy.
• Research and Analysis: Researchers study attacker behavior, tactics, and tools by observing honeypot interactions. This knowledge informs better defense strategies.
• Early Warning: If an attacker targets a honeypot, it triggers an alert. Security teams can respond promptly to potential threats

Real-life Honeypots

Honeypots are widely used in the real world to detect and study cyber threats. Organizations and security researchers deploy them to attract attackers, learn about their behavior, and improve overall security. Here are two real-world examples where honeypot techniques played a key role in uncovering malicious activity over the internet.

1. 2023: Valve caught 40,000 Dota 2 cheaters

Valve is a famous gaming company and it found and banned 40,000 players who were cheating in their game Dota 2. They did this by creating a special trap in the game, a part of the game that only cheaters using special tools could access. When players accessed this hidden part, Valve knew they were cheating and banned them. This method helped them catch a large number of cheaters at once and keep the game fair for everyone.

2. 2018: SophosLabs studied the Chalubo botnet

SophosLabs, a cyber security research team discovered a type of malware called the Chalubo botnet. This malware infected computers and made them part of a network used for cyber attacks, especially DDoS attacks. Chalubo mainly targeted computers with weak security, especially those running Linux. The researchers found that Chalubo was designed to hide well and be difficult to detect. They studied its working and it helped them prevent further attacks on it.

Advantages of Honeypot

Honeypots are traps set up to attract cyber attackers, allowing organizations to monitor malicious behavior in a controlled environment. They offer several advantages in strengthening cybersecurity defenses, as listed below:

• Acts as a rich source of information and helps collect real-time data.
• Identifies malicious activity even if encryption is used.
• Wastes hackers’ time and resources.
• Improves security.

Disadvantages of Honeypot

While honeypots are powerful in detecting and analyzing cyber threats, they are not without their limitations. Their have a few vulnerabilities, which must be considered when deploying them. Below are some common disadvantages of honeypots:

• Being distinguishable from production systems, it can be easily identified by experienced attackers.
• Having a narrow field of view, it can only identify direct attacks.
• A honeypot once attacked can be used to attack other systems.
• Fingerprinting(an attacker can identify the true identity of a honeypot ).

Conclusion

Honeypots are effective cybersecurity technologies for detecting, analysing, and mitigating cyber attacks. They help organisations strengthen their security measures by replicating hackers' targets. Despite their high cost and associated risks, honeypots play an important role in diverting attackers away from real assets and improving overall security.
