Remote access has become an essential tool for companies, IT teams and professionals who need to connect to corporate systems from anywhere. However, this model also introduces new threats, especially session hijacking, an attack in which a malicious actor intercepts or steals an authenticated session to access systems without authorization. For organizations relying on remote support, IT monitoring or off-site administration, understanding these risks and preventing them is crucial.
At Aufiero Informática, as an official reseller of tools such as TeamViewer, AnyDesk, RealVNC, Heimdal Security, Atera, NinjaOne, Microsoft, Zoho and many others, we help companies strengthen their remote infrastructure with secure, reliable and well-implemented solutions. Below is a detailed guide to understanding session hijacking and how to prevent it effectively.
What Is Session Hijacking and Why Is It Dangerous?
A remote session is the bridge between the user and the system they are accessing. When an attacker steals or intercepts the session token, they gain full control of the connection without needing passwords or any other authentication factor. This can happen due to browser vulnerabilities, insecure Wi-Fi networks, phishing, malware or misconfigurations in remote access software.
Session hijacking is particularly dangerous because the attacker appears as a “legitimate user,” making detection difficult. They can access sensitive data, alter files, install malware or compromise the entire infrastructure.
Best Practices for Securing Remote Access
1. Use secure, updated remote access tools
Choosing trusted platforms is the first step. Solutions like TeamViewer, AnyDesk and RealVNC, available through Aufiero Informática, offer end-to-end encryption, permission controls, strong authentication and detailed session logs. Keeping all systems updated protects against known vulnerabilities.
2. Implement Multi-Factor Authentication (MFA)
MFA is essential to prevent unauthorized access. Tools like Microsoft, Heimdal Security, Atera and Zoho support MFA for admin consoles, IT monitoring panels and sensitive accounts. Even if a password or session token is compromised, attackers won’t be able to authenticate.
3. Manage and rotate credentials securely
Weak or shared passwords greatly increase the risk of session hijacking. Using professional password managers and enforcing rotation policies reduces exposure. Platforms like 1Password, Microsoft, Atera and NinjaOne allow centralized credential management.
4. Monitor remote activities and connections
Constant monitoring is critical. Heimdal Security can detect suspicious behavior, abnormal connections or malicious traffic indicating session hijacking. RMM solutions such as Atera and NinjaOne offer real-time visibility across devices and remote sessions.
5. Encrypt communications and avoid insecure networks
TLS/SSL encryption is mandatory to protect data in transit. Avoid connecting through public or unsecured Wi-Fi networks. When necessary, use corporate VPNs or secure tunneling technologies from vendors like Microsoft or Heimdal Security for stronger protection.
6. Apply the principle of least privilege
Remote access tools allow granular permission controls—view only, limited actions, file transfer, or full interaction. Assigning minimum required privileges ensures that even if a session is compromised, the impact is contained.
7. Protect all devices against malware and exploits
Malware can steal cookies, credentials or network packets, enabling session hijacking. Solutions like Heimdal Security, Bitdefender, Kaspersky, Norton (GEN) and McAfee protect endpoints and reduce the attack surface significantly.
