Proxyjacking Attacks: Monetizing Hacked SSH Servers through Bandwidth Exploitation


In recent times, a new cyber threat has emerged, known as proxyjacking attacks. Cyber attackers are skillfully infiltrating vulnerable SSH servers that are exposed online, subsequently exploiting their compromised state to monetize unused bandwidth. This malicious practice allows hackers to profit by leveraging unsuspecting users’ Internet connections for various services. In this article, we delve into the mechanics of these alarming attacks and examine the repercussions they may have on individuals and organizations.
Understanding Proxyjacking Attacks:
Proxyjacking attacks target SSH (Secure Shell) servers, which are commonly used for remote administration and file transferring purposes. By scanning the internet for unsecured or poorly configured SSH servers, perpetrators gain unauthorized access to exploit them for personal gain. These attackers often employ automated tools, making it easier for them to locate vulnerable servers.
Monetizing Hacked SSH Servers:
Once hackers gain control, they redirect the servers to act as intermediaries or proxies, allowing them to sell the compromised bandwidth to shadowy entities. These entities commonly engage in activities that require multiple IP addresses, such as running botnets or engaging in illegal online activities, hiding their true identities in the process. This exploitation of hijacked SSH servers not only allows attackers to earn illicit profits but also fuels their illegal activities through the unassuming server owner’s internet connection.
Implications for Individuals and Organizations:
For individuals or small businesses that fall victim to proxyjacking attacks, the consequences can be substantial. The attackers’ exploitation of their compromised SSH servers can lead to slow internet speeds, irregular network performance, unexpected bandwidth bills, and increased vulnerability to further cyber threats. Moreover, the victims may unknowingly become involved in illicit online activities conducted by the attackers, potentially making them accountable for any illegal actions.
Mitigating Proxyjacking Attacks:
To protect oneself or their organization from falling prey to proxyjacking attacks, it is essential to adopt robust cybersecurity practices. Here are some preventive measures to consider:
  • 1. Regularly update SSH servers: Frequent software updates and security patches help defend against known vulnerabilities that attackers exploit.
  • 2. Implement strong authentication protocols: Enforce the use of complex passwords, two-factor authentication, or public key authentication to make unauthorized access more difficult.
  • 3. Limit SSH access: Configure SSH servers to only accept connections from approved IP addresses, reducing the attack surface.
  • 4. Monitor network traffic: Keep a vigilant eye on the incoming and outgoing traffic to identify any anomalous or suspicious behavior that may suggest a proxyjacking attack is underway.
  • 5. Utilize intrusion detection and prevention systems: Employing tools that can detect and halt unauthorized SSH access attempts adds an extra layer of protection against potential attackers.
Proxyjacking attacks represent a growing concern, as attackers continue to capitalize on vulnerable SSH servers to monetize unused bandwidth. By raising awareness about these attacks and implementing preventive measures, we can mitigate the risks associated with them. It is crucial for individuals, businesses, and service providers to remain vigilant and prioritize cybersecurity to protect themselves from falling victim to these exploitative practices.
