Cybersecurity Horror Stories From Ethical Hackers
Want to hear a scary story? The Lumen® Professional Security Services (PSS) team knows a few that will give you goosebumps. You may want to keep the lights on as we resurrect cybersecurity horror stories from beyond the grave to highlight the importance of proactive assessments.
What Is Pen Testing?
First, let’s define penetration testing, commonly known as “pen testing”, which is the most popular Professional Security service from Lumen. This process involves cybersecurity experts, also known as “ethical” or “white-hat hackers”, simulating cyberattacks to identify and fix vulnerabilities before malicious hackers can exploit them.
At Lumen, our pen testing services go beyond mere detection, simulating everything from basic attacks to the more advanced tactics of state-sponsored actors and sophisticated hacking collectives. Our cybersecurity experts employ bespoke AI systems to conduct thorough, scalable and tailored assessments across any digital infrastructure. This enables businesses to assess their defenses against the broadest range of potential threats, from minor vulnerabilities to critical exposure points.
Our experts have experienced some security jump scares on the job, so let’s dive into some real-life pen testing horror stories that, thanks to the Lumen PSS team, had happy endings.
The Haunted Database
For one eCommerce enterprise, a routine pen test revealed the stuff of nightmares. While everything seemed relatively normal on the surface, ethical hackers discovered an ominous backdoor in the database infrastructure that allowed unauthorized access to customer data. In the dead of night, a shadowy presence was silently exfiltrating information without triggering any alarms. Every transaction, every piece of personal data, was being siphoned away to an external server. And scariest of all—the backdoor had been open for months, and no one in the organization knew it existed.
A swift response and remediation efforts from Lumen shut down the attack, but if left undetected, this vulnerability could have led to catastrophic consequences, including massive data breaches and loss of customer trust.
The Phantom Admin
Another terrifying tale occurred during a pen test for a financial services firm, when Lumen experts found a rogue administrator profile buried deep within the network. Lurking undetected in the shadows for over a year, the phantom profile had full access to every critical system, from financial records to customer data, granting someone—or something—complete control over the organization’s most sensitive assets.
Luckily, Lumen pen testing exposed the ghostly user, preventing an attacker from exploiting the account for dastardly deeds, which could have spelled financial and reputational ruin for the company.
The Zombie Servers
One harrowing pen test that was meant to ensure the security of patient data revealed that a healthcare organization was being haunted by undead servers. Lumen experts discovered that “dead” servers running obsolete operating systems had been exploited by bad actors. The organization thought these outdated systems were inactive, but they were still connected to the network, allowing an attacker to implant malware in the network to monitor and control traffic undetected—a secret passageway for future attacks.
The implications for patient privacy and the organization’s reputation were severe, but Lumen pen testing detected and mitigated this festering threat before the zombie servers could cause irreparable damage.
Exorcise Your Network
Although inviting a third party to hack your systems may sound scary, these dark tales shed light on the importance of securing your organization through regular security assessments. Vulnerability Assessment and Penetration Testing (VAPT) services from Lumen allow customers to do more than simply check a box for compliance purposes. They empower organizations to bolster their security postures against future threats.
