How do ransomware gangs break into businesses so easily? Are they really using ultra-sophisticated tools, or are we leaving the door open?
Ransomware gangs are not always looking for the most complex or high-tech way into your systems. In many cases, they do not have to. They simply look for doors that businesses have left open. One of the most common open doors is an unpatched system.
When software and hardware are not updated with the latest security fixes, attackers can use known flaws to gain access. Once inside, they can lock up your files, steal sensitive data, and demand payment to restore access.
At Intelligent Technical Solutions (ITS), we’ve helped hundreds of organizations seal security gaps before cybercriminals exploit them.
Our experts know that one of the simplest, and most dangerous risks is an unpatched system. In this article, you’ll see why timely patching is critical and how ITS can help you build a rock-solid defense.
We’ll cover:
- Why outdated software is a top ransomware entry point
- The hidden costs of ignoring security updates
- How ITS keeps client environments secure with proactive patch management
- Practical steps you can take today
How Ransomware Gangs Really Operate
Ransomware gangs aren’t like the movie villains you’re imagining, typing away in dark rooms creating new code. Today’s cybercriminals run like real businesses. They have teams, customer service, and even franchise models.
These groups keep a close eye on security alerts from software vendors. When companies like Microsoft or firewall makers release news about security flaws, these gangs act fast. They target businesses that haven’t installed the latest updates.
Criminals don’t always need to find new flaws. They often use old ones that haven’t been fixed. That’s why ransomware attacks tend to rise soon after big security alerts are published.
The Attack Chain: From Patch to Payload
Here’s how a typical ransomware attack works when it’s based on unpatched systems:
Step 1: Vulnerability Scanning
Ransomware groups use scanning tools to check thousands of networks at once. These scans look for systems with known security gaps. Within minutes, they can find unpatched firewalls, servers, or other devices.
Step 2: Initial Compromise
Once a weak spot is found, attackers get in by using that flaw. They may break into a firewall, control a server, or take over a computer on the network.
Step 3: Network Infiltration
After getting inside, attackers look to take over more parts of the network. Goosen explains that in some instances, attackers can embed themselves in the firewall and escalate themselves to domain admin. At that point, they basically own the network.
Step 4: Data Theft and Encryption
Modern ransomware attacks usually involve two things: stealing data and locking up files. The stolen data gives attackers more power, they can threaten to leak it, even if the business recovers from backups.
Step 5: Ransom Demands
At this point, the attackers show themselves. They send a ransom note, often asking for cryptocurrency. Some even offer “support” to help victims pay and unlock their data.
4 Reasons Why Ransomware Gangs Target Unpatched Systems
Ransomware gangs prefer attacking unpatched systems for several reasons that make these businesses ideal victims:
1. Exploits Are Public Knowledge
When a vulnerability is discovered, vendors often release a patch and publish information about the flaw. Security researchers and IT teams need these details to understand the risk and fix it. Unfortunately, attackers also read these same updates. In fact, many cybercriminal forums share and sell exploit code that works against unpatched systems.
2. Attacks Can Be Automated
Ransomware gangs use scanning tools that constantly search the internet for systems with specific unpatched vulnerabilities. This scanning is cheap, fast, and runs 24/7. Once they find a target, the system is flagged for attack.
3. Unpatched Flaws Provide Quick Entry
Some vulnerabilities allow attackers to bypass authentication, execute malicious code, or gain administrator privileges. With these, criminals can install ransomware within minutes.
4. Patching Delays Are Common
Many businesses delay patches for fear of disrupting operations, especially in industries that rely on legacy systems. Others have no dedicated IT staff, meaning updates are done irregularly or not at all.
The problem is that delay could open you up for an attack. "The longer you wait, the longer your systems will be vulnerable,” warns Francois Goosen, Centralized Services Lead at ITS. “That window is all an attacker needs to get in."
The Consequences of Leaving Vulnerabilities Unpatched
The consequences of delaying patch management can vary greatly, these can include:
1. Loss of Operations
Ransomware can shut down your network, leaving employees unable to access files, email, or business applications. Even a few days of downtime can cause significant financial damage.
2. Data Theft and Extortion
Ransomware attacks often include data theft. Attackers threaten to release confidential information if the ransom is not paid, creating both a security and a compliance nightmare.
3. Financial Costs
Recovery costs extend beyond the ransom itself. They include restoring systems, replacing hardware, paying for incident response teams, and covering lost revenue during downtime.
4. Compliance Violations
If you operate under regulations like HIPAA, CMMC, or PCI DSS, failing to apply patches can be considered a violation. This can result in heavy fines and legal penalties.
5. Reputational Damage
Clients and partners may lose trust in your ability to protect their data. Restoring that trust can take years.
How to Stop Ransomware Gangs from Exploiting Your Systems
Protecting your business from ransomware requires a comprehensive approach that goes beyond just installing patches, though timely updates remain the foundation of good security.
1. Implement a Robust Patch Management Program
A proactive patch management program ensures vulnerabilities are fixed before attackers can exploit them. Effective programs include:
- Asset Inventory: Keep a list of all devices and software in use. If you do not know what you have, you cannot patch it.
- Patch Prioritization: Apply critical security patches immediately, even if it means scheduling short maintenance windows.
- Automation: Use tools that push patches to all devices, including remote laptops, without waiting for manual updates.
- Verification: Confirm that patches have been applied successfully by checking reports from your patch management tool.
2. Monitor for Vulnerabilities Continuously
Do not rely on a once-a-month patch cycle. Cybercriminals do not wait for your schedule. Continuous vulnerability scanning can:
- Detect new issues as they arise.
- Identify systems that may have missed patches.
- Help prioritize which flaws to address first based on their risk level.
3. Develop an Incident Response Plan
Even with strong defenses, no system is completely safe. A solid incident response plan allows you to act quickly if ransomware strikes:
- Isolation Procedures: Disconnect infected systems from the network immediately.
- Communication Guidelines: Ensure employees know whom to notify and what information to provide.
- Backup Restoration: Have clean, offline backups ready so you can restore systems without paying the ransom.
- Escalation Steps: Know when and how to involve law enforcement or third-party cybersecurity teams.
4. Partner with a Managed Security Service Provider (MSSP)
A trusted MSSP like ITS can strengthen your defenses with:
- 24/7 threat monitoring.
- Automated and verified patch deployment.
- Vulnerability assessments to identify weak points before attackers do.
- Expert response teams to contain and mitigate attacks quickly.
5. Educate Your Staff
Human error plays a big role in ransomware attacks. Even if a vulnerability is patched, phishing emails or poor security habits can still let attackers in. Ongoing training should cover:
- The importance of applying updates promptly.
- How to recognize phishing attempts and suspicious behavior.
- Safe practices for remote work and personal devices used for business.
Ready to Keep Ransomware Gangs from Taking Advantage of Unpatched Systems?
Ransomware gangs will continue exploiting unpatched systems as long as businesses provide easy targets. The good news is that most attacks are preventable with proper security practices.
Start by auditing your current patch management processes. Who is responsible for monitoring security updates? How quickly can you deploy critical patches? Are all your systems receiving regular updates?
If you don't have good answers to these questions, it's time to either invest in proper patch management resources or work with experienced security professionals.
