VI - How Hackers Exploit Weaknesses in Your Business Network & How to Avoid Being a Victim

From TIPS, AND INSIGHTS TO HELP NAVIGATE THE DIGITAL WORLD SECURELY

In a previous article (Essential Cybersecurity Tips for Beginners)1 we have learned how understanding the basics of cybersecurity can help protect your personal information, financial assets, and digital identity.

 

In this article, we'll review common attack vectors, how lateral movement works in cyberattacks, and how advanced solutions like ARCHANGEL 2.0 Next Generation Firewall (NGFW) by PT SYDECO can help prevent unauthorized code execution and secure your network.

 

I - Common Attack Vectors: Phishing, Malware, and Privilege Escalation

 

1. Phishing Attacks

 

Phishing is one of the most common and effective attack vectors. Hackers use deceptive emails, messages, or websites to trick employees into revealing sensitive information such as login credentials or financial data. Once hackers gain access to a user’s account, they can infiltrate the network and cause significant damage.

 

How to Avoid Being a Victim:

 

  • Employee Training: Regularly train employees to recognize phishing attempts. Conduct simulated phishing exercises to test their awareness.
  • Email Filtering: Use advanced email filtering solutions to detect and block phishing emails before they reach employees’ inboxes.
  • Multi-Factor Authentication (MFA): Implement MFA to add an extra layer of security, even if credentials are compromised.

 

2. Malware Infections

 

Malware, including ransomware, spyware, and trojans, is designed to infiltrate systems and cause harm. Malware can be delivered through malicious email attachments, infected websites, or even USB drives. Once inside the network, malware can steal data, encrypt files, or provide hackers with remote access.

 

How to Avoid Being a Victim:

 

  • Endpoint Protection: Deploy robust antivirus and anti-malware solutions on all devices connected to the network.
  • Regular Updates: Keep all software and systems up to date with the latest security patches to close vulnerabilities that malware exploits.
  • Network Segmentation: Use micro-segmentation to isolate critical systems and limit the spread of malware.

 

3. Privilege Escalation

 

Privilege escalation occurs when hackers gain access to a low-level user account and then exploit vulnerabilities to gain higher-level privileges, such as administrative access. This allows them to control the network, install malicious software, or exfiltrate sensitive data.

 

How to Avoid Being a Victim:

 

  • Least Privilege Principle: Ensure that users only have access to the resources necessary for their roles. Limit administrative privileges to a select few.
  • Regular Audits: Conduct regular audits of user accounts and permissions to identify and rectify any unnecessary privileges.
  • Intrusion Detection Systems (IDS): Implement IDS to monitor for unusual activity that could indicate privilege escalation attempts.

 

II - How Lateral Movement Works in Cyberattacks

 

Lateral movement refers to the techniques hackers use to move through a network after gaining initial access. Once inside, hackers can exploit weak points to access other systems, escalate privileges, and ultimately achieve their goals, such as stealing data or deploying ransomware.

 

Steps in Lateral Movement:

 

1.     Initial Compromise: Hackers gain access to a single device or user account, often through phishing or malware.

2.     Reconnaissance: They gather information about the network, such as IP addresses, user accounts, and shared resources.

3.     Exploitation: Hackers exploit vulnerabilities or weak credentials to move to other devices or systems.

4.     Persistence: They establish a foothold by creating backdoors or installing malware to maintain access.

5.     Exfiltration or Damage: Finally, hackers steal data, deploy ransomware, or cause other forms of damage.

 

How to Prevent Lateral Movement:

 

  • Micro-Segmentation: Divide the network into smaller, isolated segments to limit the spread of attacks. Each segment should have its own security controls.
  • Zero Trust Architecture: Implement a Zero Trust model, where no user or device is trusted by default, even if they are inside the network.
  • Network Monitoring: Continuously monitor network traffic for unusual activity that could indicate lateral movement.

 

III - How ARCHANGEL 2.0 NGFW Prevents Unauthorized Code Execution

TIPS, AND INSIGHTS TO HELP NAVIGATE THE DIGITAL WORLD SECURELY - V -The Hidden Dangers of Free Wi-Fi and How to Stay Safe

 In a previous article (Essential Cybersecurity Tips for Beginners)1 we have learned how understanding the basics of cybersecurity can help protect your personal information, financial assets, and digital identity.

While it’s tempting to connect to free Wi-Fi for convenience, doing so without precautions can expose your sensitive information to hackers.

In this article, we’ll explore the dangers of free Wi-Fi, how attackers exploit these unsecured networks, why relying on third-party VPN services can also be risky, and why running your own VPN server at home or using a secure solution like Archangel is the best way to stay protected. We will also explore practical tips to protect yourself and your data.

 

WHY FREE WI-FI IS DANGEROUS

 

Public Wi-Fi networks are unsecured by nature, making them a hunting ground for cybercriminals. These networks lack proper encryption, allowing hackers to intercept communications, steal login credentials, and monitor your online activity.

 

Some of the key threats include:

 

1.     Man-in-the-Middle (MITM) Attacks

In a MITM attack, a hacker positions themselves between your device and the network. They can intercept communications, steal login credentials, and monitor sensitive information like emails, banking details, and more.

Example: You connect to a free Wi-Fi network at an airport and check your bank account. Without encryption, a hacker can intercept that traffic and capture your credentials.

 

2.     Evil Twin Attacks (Fake Hotspots)

Hackers create fake Wi-Fi networks with names that mimic legitimate ones. Once you connect, they can monitor all your activities or inject malicious content.

Example: A network called "Coffee_Shop_Free_WiFi" may not belong to the café at all but could be a hacker’s trap.

 

3.     Malware Injection
Some compromised networks can inject malicious software onto your device, infecting it with ransomware, spyware, or other types of malwares.

 

HOW TO PROTECT YOURSELF ON PUBLIC WI-FI

 

1.     Use a VPN—But Be Careful Which One You Choose

A VPN (Virtual Private Network) encrypts your internet traffic, making it unreadable to anyone trying to intercept it. It’s an essential tool for securing your connection on public Wi-Fi. However, not all VPNs are created equal.


The Dangers of Using Third-Party VPNs: 

·         Data Logging Risks: Some free or low-cost VPN providers log your browsing activity and sell your data to third parties. 

·         Security Vulnerabilities: Many free VPNs lack proper encryption protocols, making you vulnerable to attacks. 

·         Hidden Malware: Some free VPN apps contain malware disguised as security tools.

 

The Safest Solution: Run Your Own VPN Server at Home

For true security and control over your data, the best option is to set up your own VPN server. By hosting your VPN at home, you eliminate the risks associated with third-party providers.

With Archangel© 2.0, the advanced firewall solution from PT SYDECO, you can easily set up a secure VPN server at home. Here’s why this is the safest approach:

·         Full Control: You own the server and the data passing through it.

·         Better Privacy: No third-party access to your traffic or logs.

·         Enhanced Security: Integrated protection with Archangel © 2.0 Next-Generation Firewall (NGFW) to block unauthorized access and prevent malware.

 

How to Use a VPN Safely

If you have not your own VPN server yet, follow these steps to use a VPN securely:

1.     Choose a Reputable VPN Service: If you must use a third-party VPN, avoid free options and research providers known for strong encryption and no-logging policies.

2.     Connect to the VPN Before Accessing Public Wi-Fi: Always activate your VPN before joining a public network.

3.     Verify the VPN Connection: Ensure the VPN is connected and that your traffic is being routed through the encrypted tunnel.

 

2.     Other Security Measures You Should Take

 

1.     Verify the Network Name

Before connecting to a public Wi-Fi network, confirm its legitimacy with the staff or owner of the establishment.

Practical Tip: Avoid networks with suspicious names or those that don’t require any authentication.

 

2.     Use HTTPS Websites Only

HTTPS (Hypertext Transfer Protocol Secure) ensures that your connection to a website is encrypted. This adds an extra layer of security.

Practical Tip: Look for the padlock symbol in your browser’s address bar to confirm you’re on an HTTPS website.

 

3.     Disable Automatic Connections

Many devices automatically connect to known Wi-Fi networks. This feature can be exploited by hackers who create fake networks with familiar names.

Practical Tip: Turn off automatic Wi-Fi connections and connect only when necessary.

 

4.     Use Two-Factor Authentication (2FA)

Even if a hacker manages to steal your password, 2FA can prevent them from accessing your accounts.

Practical Tip: Enable 2FA on all your accounts—especially for email, banking, and social media.

 

ADVANCED PROTECTION MEASURES

 

For those who want to take security a step further, consider these additional measures:


  • Use a Personal Hotspot: When possible, use your smartphone’s mobile hotspot instead of public Wi-Fi.
  • Install Security Software: Use up-to-date antivirus and firewall software to protect your devices.
  • Avoid Sensitive Transactions: Never access banking apps or enter personal information on public Wi-Fi.

 

Why a Home VPN Server is the Future of Personal Security

 

The concept of building a personal VPN server is no longer just for tech enthusiasts. With solutions like Archangel© 2.0, it’s possible to create a highly secure home network that allows you to connect safely from anywhere in the world.

By running your own VPN, you avoid the pitfalls of free public networks and gain complete control over your security and privacy—whether you’re at a café or traveling abroad.

 

In summary

Free Wi-Fi is a double-edged sword—it offers convenience, but without the right precautions, it can expose you to significant risks. Understanding the dangers and implementing the protective measures outlined in this article will help you stay secure while staying connected.
