The invisible threat 

The vulnerabilities of remote support tools can expose your company to severe remote access vulnerabilities and ransomware attacks.  

In today’s digital landscape, remote help desk systems are essential for managing and supporting corporate IT infrastructure. But while they simplify technical support, these same systems can become prime entry points for cybercriminals—posing significant threats to corporate security. 

Exploiting remote access tools can lead to data breaches, theft of intellectual property, and ransomware attacks, all of which jeopardize business continuity and operations. 

  

How does remote help desk work? 

Remote support software allows a technician’s computer ("host") to monitor and control a remote device ("target"). Once connected, the technician can see and interact with the remote system’s interface, making IT support more efficient—but also more vulnerable if poorly secured.  

  

The growing threat to remote help desk platforms 

Remote help desk systems have become increasingly attractive to cybercriminals for two main reasons: 

• They often provide direct access to a company’s internal infrastructure. 

• They typically operate with elevated privileges necessary for resolving technical issues. 

Since 2024, remote access vulnerabilities have grown in sophistication. Attackers now launch broad campaigns exploiting known flaws in popular platforms. Meanwhile, low-skill threat actors also leverage commoditized hacking tools.  

The widespread availability of attack tools has also lowered the entry barrier, enabling even low-skill attackers to execute effective intrusions—dramatically expanding the threat surface. 

  

The TeamViewer case 

One of the most notable recent examples involves TeamViewer—a widely used remote access tool. Cybercriminals have exploited this platform to breach corporate networks and deploy ransomware, encrypting files and demanding payment for decryption. 

Back in 2016, multiple users reported that their devices were compromised via TeamViewer and infected with the “Surprise” ransomware. At the time, TeamViewer clarified that the breach didn’t result from a software flaw, but from attackers using stolen credentials obtained from other online services. 

Fast forward to 2024, and TeamViewer once again became a launchpad for ransomware attacks—specifically LockBit 3.0. In some cases, the ransomware encrypted corporate data; in others, security tools intervened in time to block the attack. 

The company pointed out that most unauthorized access incidents stemmed from poor user-side security configurations. Common risk factors included weak or already-compromised passwords, outdated software versions, and the absence of multi-factor authentication (MFA). 

  

How attackers take control of remote support tools 

Remote support software isn’t inherently dangerous. But if not configured and protected properly, it can become an open door for attackers. 

Companies and IT staff should be vigilant about the following common attack vectors: 

1. Weak or compromised credentials 

   One of the most frequent vulnerabilities is poor password hygiene. Weak, reused, or shared credentials are an easy target. Technicians often use accounts with elevated privileges—if compromised, attackers could gain access to critical systems. 
   
   

2. Lack of Multi-Factor Authentication (MFA) 

   Many remote support platforms are still deployed without requiring MFA, leaving systems exposed to anyone who obtains a username and password. This is particularly dangerous for internet-facing systems where attackers can attempt access with no physical limitations. 
   
   

3. Unpatched software vulnerabilities 

   Remote support tools require regular updates to patch security flaws. However, many organizations delay these updates to avoid service interruptions. This negligence gives attackers a window to exploit known vulnerabilities for which public exploits already exist.
   
   

4. Unprotected sessions and unencrypted communication

    Support sessions without encrypted communication channels risk exposing sensitive data. Even when encryption is used, misconfigured setups can still leak protected information during live support sessions.
   
   
5. Over-privileged access 
   Support technicians often have more privileges than necessary for their role. While this accelerates issue resolution, it significantly amplifies the damage potential if the account is compromised.
   
   
6. Integration with enterprise systems 
   Modern help desk tools are often integrated with various business applications—widening the attack surface. If not properly secured, these integrations can become Trojan horses enabling lateral movement across systems like customer databases or ERP platforms. 

  

Common attack vectors

Below are some of the most common methods used by attackers to compromise remote help desk systems: 

• Social engineering and spear phishing

  Attackers frequently use social engineering to trick IT staff into handing over credentials or installing malware. Spear phishing campaigns targeting IT personnel are particularly effective, as they mimic trusted messages from executives or tech partners. 

• Exploiting known vulnerabilities

Cybercriminals constantly monitor security advisories for popular remote support tools. As soon as a new vulnerability is disclosed, attackers begin scanning the internet to identify and exploit unpatched systems. 

• Supply chain attacks 

A growing concern is the rise in supply chain attacks, where attackers compromise the vendors of help desk tools to distribute malware through legitimate software updates—reaching the vendor’s entire customer base. 

  

RemoteGrant: innovation and security in remote support

CyberGrant’s advanced DLP (Data Loss Prevention) software, RemoteGrant, secures remote support tools like TeamViewer while maintaining productivity. 

RemoteGrant Enforces Zero Trust architecture for remote sessions and ensures that remote support tools—like TeamViewer and similar platforms—are used safely by blocking unauthorized access and preventing malware installation. It also shields sensitive data during support sessions. 

With RemoteGrant installed on every company laptop, businesses can: 

• Continue using remote support tools under strict security policies. 

• Automatically block any attempt to access sensitive folders or files. 

• Prevent external users from executing suspicious or potentially harmful files, safeguarding systems from infection. 

This minimizes the risk of data theft via remote support tools while preserving business continuity. Help desk operations continue seamlessly, without sacrificing productivity. 

Additionally, RemoteGrant employs transparent encryption: all documents created or handled on corporate devices are automatically encrypted in the background. Files saved in specific folders are only accessible from policy-authorized machines. If copied elsewhere, they remain unreadable. 

What’s more, RemoteGrant can be fully tailored to a company’s unique needs. Its flexible policy engine allows businesses to adapt and combine rules to meet specific security goals and compliance requirements for cyber resilience. 

RemoteGrant also supports: 

• Detailed event logs for incident analysis. 

• Alerting policies with customizable severity levels—enabling faster, more efficient security incident response. 

  

Conclusion 

Remote support tools will remain a favored target for cybercriminals. That’s why businesses must double down on cyber resilience—protecting themselves from financial loss, reputational damage, and legal consequences tied to these attack vectors. 

In short, adopting a proactive approach to securing these critical systems—like the one offered by CyberGrant’s RemoteGrant—is no longer optional. It’s an absolute necessity for any business aiming to thrive in the digital economy and stay compliant with cybersecurity regulations.
