The Silent Threat of End-of-Life Tech—and How Cybercriminals Exploit Trust to Attack



As we observe Cybersecurity Awareness Month this October, it's time to confront a growing vulnerability that affects everything from industrial systems to personal devices: end-of-life (EOL) technology. These outdated systems are not just inefficient—they’re dangerous. Worse, cyber threat actors are getting smarter, using trusted U.S. network traffic as camouflage to launch attacks that bypass traditional defenses.

What Is End-of-Life Technology?

When a device or software reaches EOL, it means the manufacturer has stopped providing:

  • Security patches
  • Bug fixes
  • Technical support

This leaves the system exposed to known vulnerabilities—many of which are publicly documented and easily exploited.

How Cybercriminals Exploit EOL Devices

Threat actors actively scan for outdated systems and use them as entry points. Once inside, they:

  • Deploy ransomware
  • Steal sensitive data
  • Use compromised devices as launchpads for lateral movement across networks

According to the National Cybersecurity Alliance’s 2025 “Oh Behave!” report, 44% of individuals experienced cybercrime that led to data or monetary loss—a 9% increase from the previous year. Many of these incidents stemmed from outdated or poorly secured devices.

Trusted Traffic: The Trojan Horse of Cyber Attacks

One of the most insidious tactics used by cybercriminals is leveraging traffic from trusted networks—especially those originating in the United States. Here’s how it works:

  • Geo-trust bias: Many organizations whitelist traffic from U.S.-based IP addresses, assuming it's safe.

  • VPN and proxy abuse: Threat actors route malicious traffic through compromised U.S. servers to avoid detection.

  • Supply chain infiltration: Attackers compromise vendors or partners with U.S. infrastructure, gaining indirect access to target systems.

This tactic is particularly effective in manufacturing, where legacy systems often lack modern threat detection, and in home networks, where consumer-grade firewalls may not scrutinize geographic origin.

Real-World Impact: From Factory Floors to Family Rooms

  • Manufacturing: Legacy industrial control systems (ICS) are often unpatchable. Once breached, attackers can halt production, corrupt data, or even cause physical damage.

  • Home networks: Old routers, smart TVs, and IoT devices are often forgotten but remain connected. Once compromised, they can be used to spy, steal credentials, or launch attacks on other devices.

Why MDM Is Essential for Modern Cyber Defense

Mobile Device Management (MDM) is critical for organizations   It enables:

  • Remote monitoring and patching
  • Policy enforcement across devices
  • Instant lockdown or wipe of compromised endpoints
  • Visibility into device health and compliance

MDM is especially vital in remote work environments, where personal devices often access corporate resources.

Building Cyber Resilience This October

As we celebrate Cybersecurity Awareness Month, here’s how to stay ahead:

  • Audit your tech: Identify and replace EOL devices.
  • Segment your network: Isolate legacy systems from critical infrastructure.
  • Scrutinize traffic: Don’t blindly trust geographic origin—use behavioral analytics.
  • Deploy MDM: Ensure all endpoints are secure and manageable.
  • Educate your team: Cyber hygiene starts with awareness.

Final Thought

Cybersecurity isn’t just about firewalls—it’s about foresight. EOL devices and trusted traffic are the perfect storm for attackers. But with vigilance, modern tools like MDM, and a commitment to cyber resilience, we can turn vulnerabilities into victories.

From Dormant to Dangerous: Understanding the security risk of dormant user accounts

Image
  In today's digital era, the security of cloud SaaS systems is paramount. An often-neglected aspect of cybersecurity is the management of dormant user accounts, which can unintentionally become gateways for cybercriminals, leading to significant data breaches. The process of regularly auditing and deactivating these inactive accounts is vital to safeguard the integrity and security of an enterprise. By ensuring that only active, necessary users have access to your resources, you minimize the risk of unauthorized access and strengthen your defense mechanisms. This guide delves into the necessity of tackling this issue head-on and outlines effective strategies for managing dormant accounts to secure your valuable data assets. Risks Associated with Dormant User Accounts Dormant user accounts are ticking time bombs in the realm of cybersecurity. These accounts, often forgotten or overlooked after an employee's departure or during system migrations, present a significant security r...

World Backup Day: The Indispensable Role of Data Backups and Cautionary Tales of Data Loss

Image
World Backup Day is observed annually on March 31st, serves as a reminder of the critical importance of data backups in today's digitally driven world. This day underscores the undeniable fact that data loss, whether due to human error, system failure, or malicious acts by threat actors, is not a matter of 'if' but 'when'. The Unquestionable Importance of Data Backups In the present digital era, data is arguably one of the most valuable assets for both individuals and organizations. From irreplaceable personal photos and videos to crucial business documents and customer data, digital information forms the backbone of our personal and professional lives. Consequently, data loss can have devastating consequences, leading to significant emotional distress for individuals and potentially crippling financial losses for businesses. The Harsh Reality of Data Loss Data loss is a pervasive and inevitable occurrence in our digitally interconnected world. According to the 2024...

Automate the schedule of AR invoices and statements using the Plex ERP Document Delivery module.

Image
Manual invoicing and emailing of customer statements can be a time-consuming and resource-intensive process. According to a study by Skynova, most businesses handle up to 500 invoices each month and spend at least five days processing invoices .  The same study also found that 57% of invoice data is entered manually and 49% of businesses require two to three people to approve an invoice. These manual processes can lead to delays in payment and inefficiencies in the accounting process. Invoicing automation can help reduce the time and resources spent on manual invoicing. According to Skynova,Only about half of invoices (52%) are received electronically. The rest are paper invoices that need to be physically sorted, entered, and filed, adding additional steps to the invoice process. The following module in Plex manufacturing allows automatically delivery AR invoices and customer statements via email which can lead to improvement and reduce of the waste of resources associated by manu...
