How To Detect Hackers On Your Network

We live and work in an era where digital security is paramount. Small and medium-sized businesses must establish robust cybersecurity measures and remain vigilant for signs of network breaches. A reactive stance is no longer sufficient. Your business needs proactive monitoring, and timely responses are crucial in safeguarding your business against cyber threats.

This article will explore the signs that your network has been hacked and strategies to enhance your business’s cyber defenses.

7 Signs Your Network Has Been Hacked

1. New Programs or Software Has Been Installed

One of the most glaring signs that your network has been hacked is the discovery of unauthorized software installations. These rogue applications, often installed without the knowledge of IT administrators, can create backdoors for hackers, exposing your network to further intrusions. This phenomenon, known as “Shadow IT,” represents a significant threat to your company’s data and intellectual property security.

How To Monitor Changes In Your Operating Systems:

• Implement strict protocols for software installation, ensuring that only approved applications are used.
• Create a comprehensive list of sanctioned software and vendors for all employees.
• Employ advanced network monitoring tools that can detect and alert you to the presence of unknown devices or software.
• Conduct detailed and regular data audits, helping you to maintain an overview of all digital content being created, shared, or stored within your company’s network.

2. SPAM Emails Sent From Your Accounts

If your company’s email system begins sending out SPAM, it strongly indicates that your network has been hacked. This type of breach compromises the integrity of your business communications and risks spreading malware to your contacts and other network users.

Strategies to Protect Your Business From SPAM:

• Implement two-factor authentication across all company email accounts. This will add an extra layer of security against unauthorized access.
• Utilize sophisticated anti-spam solutions that detect and block phishing attempts, including more targeted attacks like spear-phishing and whaling.
• Regularly educate your employees about the dangers of phishing scams and the importance of vigilance in recognizing and reporting suspicious emails.

3. An Unusual Increase In Network Activity 

An unexpected increase in network activity, even in the absence of SPAM emails, is a telltale sign of a compromised network. Such an increase in unusual activity can indicate that an external party has bypassed your firewall, using your network resources for malicious purposes. This can significantly slow your internet connectivity, hindering internal and external business operations.

4. Unauthorized Access Requests

When employees receive unexpected network or software access requests, especially from unfamiliar programs, it could indicate that your network has been hacked. Often, these requests can slip under the radar as employees focus on their daily tasks, unwittingly granting access to malicious software.

5. Firewalls or Security Programs Have Been Uninstalled

The deactivation or uninstallation of security programs and firewalls is a critical indicator that your network has been hacked. Such actions leave your network vulnerable to a wide array of cyber threats. Prompt reinstallation and updating of these security measures are essential to protect your business from malware, data breaches, and other cyber risks.

6. Default Browser Homepage Has Changed

Changes to your default browser settings, such as altered homepages or new, unfamiliar toolbars, often go unnoticed but indicate a network breach. Regular checks of your digital workspace can help in early detection of such intrusions. Hiring a managed IT service provider like CyberGate IT is a great way to protect your network from cyber threats.

7. Computer Operates On Its Own

When computers in your network begin operating independently, as if controlled remotely, it’s a clear sign of a security breach. This situation suggests that an unauthorized party has gained remote access, potentially compromising sensitive information and disrupting business operations.
