Ethereum: Is there a way to make bitcoin addresses of blacklist or to follow?
The growing trend of ransomware attacks against Bitcoin users has led to an increase in interest among cybersecurity experts and law enforcement agencies. A question that has been in many spirits is whether it is possible to list black or to follow the Bitcoin addresses associated with these malicious activities.
Context: Ransomware Attacks on Bitcoin
Ransomware is a type of malware that encrypts a victim’s files, demanding payment in exchange for the decryption key. Although ransomware attacks can be devastating, especially when targeting businesses and organizations, individuals are also increasingly targeted. In recent years, the rise in cryptocurrency has allowed hackers to more easily exploit Bitcoin portfolios and request ransom payments.
Black List or follow -up of Bitcoin addresses
There is no full list available that specifically targets the Bitcoin addresses used by ransomware attackers. However, several organizations have tried to follow and identify these malicious activities:
- Chainalysis : This company offers blockchain analysis tools which help follow cryptocurrency transactions, including those associated with ransomware attacks.
- Helix Labs : Helix Labs provides a platform to follow the activity of cryptocurrencies, which includes the identification of suspicious addresses used by ransomware attackers.
- Coinjoin : Coinjoin is an open-source service that allows users to combine their Bitcoin transactions in a single anonymized outing. This makes it more difficult to monitor individual transactions, but some researchers have tried to use this technique to identify specific malicious addresses.
Limits of the black list or follow -up
Although these efforts can provide valuable information on the activities of ransomware attackers, there are several limits to consider:
- Anonymat : Many Bitcoin users remain anonymous, which makes it difficult to locate the individual addresses associated with a particular attack.
- Sophisticated techniques : Ransomware attackers often use sophisticated techniques, such as encryption and switching of the wallet, to escape detection.
- Constant evolution : Tactics, techniques and procedures (TTP) used by Ransomware attackers are constantly evolving, making it essential organizations to stay up to date with the latest threats.
Efforts of organizations
Several organizations have taken measures to combat ransomware attacks using Bitcoin:
- Microsoft : Microsoft has implemented various safety measures, including improved portfolio encryption and regular updates, to reduce the risk of ransomware attacks.
- SEGA : SEGA has developed a system based on the blockchain which allows users to follow and identify suspicious transactions.
- Cryptopay : Cryptopay is an organization focused on the development of secure payment systems, including those that use Bitcoin.
Conclusion
Although it is difficult to set up completely black or follow the Bitcoin addresses associated with ransomware attacks, several organizations work tirelessly to fight against these threats. By remaining informed of the latest techniques and measures taken, individuals and businesses can reduce their risk of being the victim of these malicious activities.
