Threat intelligence is essential for detecting, evaluating, and reducing possible security threats in the dynamic field of cybersecurity. By identifying dangerous activities and vulnerabilities, threat intelligence assists organisations in staying ahead of hackers. The usage of anonymity networks is one of the key elements of contemporary threat intelligence. By concealing users’ identities, these networks offer an extra degree of protection and privacy by making it more difficult for bad actors to monitor or trace online activity.

In this paper, we investigate the connection between threat intelligence and anonymity networks. The potential hazards they present to both individuals and organisations, as well as how they are used in cybersecurity.

Comprehending Anonymity Networks

Systems called anonymity networks are made to hide users’ location and identity online. They work by directing internet traffic via a number of nodes, which makes it challenging to identify the traffic’s source. Tor (The Onion Router) is the most well-known example of an anonymity network. As the name suggests, Tor employs a decentralised network of computers run by volunteers to encrypt user traffic through multiple layers, thereby making it anonymous.

However, one of the most well-known networks is Tor. Other anonymity technologies that offer internet users anonymity include Freenet and I2P (Invisible Internet Project).

People who want to protect their privacy or get around restrictions are the main users of these networks. However, they have made a name for themselves in the larger field of cybersecurity, particularly in threat intelligence.

Anonymity Networks’ Function in Threat Intelligence

Information concerning possible risks that can jeopardise an organization’s security is gathered, examined, and disseminated as part of threat intelligence. The objective is to foresee and reduce cyberthreats before they have the potential to do serious damage. In this process, anonymity networks are essential and have two effects.

First, without disclosing their identify, cybersecurity experts may study and keep an eye on the dark web and other obscure areas of the internet thanks to anonymity networks. In these hidden corners of the internet, a large number of cybercriminals discuss illegal actions, sell stolen data, and share hacking skills. Security analysts can obtain important information about new risks while hiding their own actions from possible attackers by utilising anonymity networks.

Second, bad actors frequently take use of anonymity networks themselves. These networks are used by cybercriminals to conduct illicit activities while concealing their location and identity. Because of this, it is difficult for cybersecurity and law enforcement agencies to find and capture them. Therefore, for threat intelligence operations to be effective, it is essential to comprehend how these networks are used in threat activities.

The Use of Anonymity Networks in Cyberattacks

Although anonymity networks give people important privacy advantages, they also give cybercriminals a cover to operate behind. Attackers employ these networks for a number of illegal objectives, such as:

• Data Theft and Trafficking: Cybercriminals can sell credit card numbers, login credentials, and stolen personal information on underground marketplaces by using anonymity networks. Because these transactions are hard to track down, authorities find it tough to step in.
• Command and Control Servers: In order to manage botnets or other malicious infrastructure, hackers frequently set up command-and-control servers using anonymity networks. They can conceal their whereabouts and make it more difficult for investigators to dismantle their operations by employing these networks.
• Distributed Denial of Service (DDoS) assaults: A network of compromised devices is frequently used in DDoS assaults. It can be managed through anonymity networks’ hidden servers. Because of this decentralisation, stopping the attack is more difficult.
• Deployment of malware: Cybercriminals can conceal their true location and identity by using anonymous networks to spread malware. It is more difficult to track and stop ransomware campaigns because of this anonymity.

Using Networks for Anonymity to Safeguard Organisations

Anonymity networks are useful for legal cybersecurity procedures, even if they are frequently linked to malicious conduct. To protect their identities and obtain intelligence in regions that would otherwise be too unsafe or dangerous, analysts use anonymity networks. Anonymity networks assist organisations in the following ways:

• Examining Dark Web Marketplaces: Cybercriminals purchase and sell illicit goods and services on the dark web’s numerous underground marketplaces. Threat intelligence teams can learn more about these markets and follow illegal activity without putting themselves in danger by utilising anonymity networks.
• Secure Data Collection: Cybersecurity experts frequently have to obtain information from sources that may be compromised or monitored in order to compile intelligence on risks. They can accomplish this without endangering themselves or their organisations thanks to anonymity networks.
• Combating DDoS Attacks: To examine and address DDoS attacks, security professionals might employ anonymity networks. Utilising these networks aids in identifying attackers and safeguarding response operations because these assaults frequently come from anonymous sources.

The Difficulties and Hazards of Anonymity Networks

Anonymity networks provide serious hazards and obstacles despite their benefits in threat intelligence. Both cybersecurity experts and the organisations that depend on them for security may be impacted by these issues:

Attracting Malevolent Actors: These networks draw criminal behaviour by enabling anonymous communication. When security teams use anonymity networks to seek down fraudsters, this might lead to a dilemma. However, those criminals might use those same networks to avoid detection.

False Positives in Threat Detection: Security teams may have trouble telling the difference between good and bad actors since anonymity networks can conceal the identities of both malicious and legitimate users. Security teams may wrongly flag benign activities as a danger, leading to false positives.

Legal and Ethical Issues: There may be ethical and legal issues with tracking and examining traffic on anonymity networks. For example, interacting with anonymous users or accessing specific parts of the black web may be viewed as violating privacy rights or international laws.

Attribution Difficulty: Attribution is one of the most significant cybersecurity concerns. or the capacity to identify the source of an assault. By their very nature, anonymity networks make this process very challenging, which can impede law enforcement investigations and delay response operations.

The Best Ways to Use Anonymity Networks for Threat Intelligence

Organisations must use anonymity networks in their threat intelligence initiatives according to best standards because of the risks and complexity involved. Here are a few suggested methods:

• Make Use of Specialised Tools: To monitor and examine traffic on anonymity networks, there are specialised cybersecurity tools available. While lowering the dangers of exposure, these solutions can assist in detecting malicious activities and providing real-time notifications.
• Provide Regular Training: Regular training and education for cybersecurity experts is crucial because anonymity networks are a somewhat specialised field of cybersecurity. Analysts must understand how to use these networks efficiently and remain current on the most recent dangers.
• Work with Legal Authorities: For organisations looking to take action against cybercriminals operating within anonymity networks, cooperation with law enforcement agencies is essential. Laws pertaining to the usage of these technologies are always changing. Additionally, cybersecurity teams must understand the legal limits.
• Emphasis on Threat Correlation: Cybersecurity teams should correlate data from many sources rather than depending only on information gleaned from anonymity networks. encompassing endpoint analysis, network traffic, and traditional intelligence. More accurate threat intelligence may be found with the aid of this comprehensive technique.

In conclusion

There are advantages and disadvantages to anonymity networks in the fields of threat intelligence and cybersecurity. Even so, they have a lot to offer in terms of intelligence collection and privacy protection. Malicious actors who want to conceal their actions also find refuge there. Recognising anonymity networks’ function. For cybersecurity experts and companies looking to keep ahead of changing threats, understanding the dangers they present and how to employ them effectively is essential. by using the appropriate tools and implementing best practices. Threat intelligence teams can employ anonymity networks to improve overall cybersecurity and reduce the threats they pose.
