A large industrial production facility supplying bakeries would never have expected to uncover so many security weaknesses. From the outside, operations appeared well organized, professional, and focused on efficiency. Production lines were running, systems were in place, and daily routines had worked reliably for years.
Cybersecurity was not ignored, but it was not seen as a critical risk either. Like many manufacturing environments, the company assumed that serious cyberattacks were more likely to affect digital companies, financial institutions, or large technology firms. A production-focused organization, supplying bakeries, did not seem like an obvious target.
This perception changed once the company decided to take a closer look at its real exposure. What followed was not the discovery of a single major flaw, but a series of small, familiar weaknesses. Unattended computers, weak Wi-Fi protection, outdated IT equipment, and missing verification when unknown individuals entered the facility. None of these issues seemed dramatic on their own. Together, however, they created a realistic path into both the company’s systems and its physical environment.
The case shows that cybersecurity risks do not depend on industry labels or company size. They grow out of everyday routines, habits, and assumptions. The simulated attack did not reveal a careless organization. It revealed a normal one — operating under the belief that serious incidents happen elsewhere.
The real value of this exercise was not fear, but clarity. It demonstrated where risks truly exist, how easily they can be exploited, and why prevention must begin long before a real incident forces action.
The Setup: A Simulated Penetration Test
The company, a manufacturing and production facility serving bakeries, agreed to take part in a controlled penetration test to better understand its real security risks. This was not an emergency situation and not a response to a previous attack. It was a proactive decision to evaluate how the organization would perform under realistic conditions.
A team of ethical hackers was tasked with testing the company’s defenses from an attacker’s point of view. Their role was to think and act like real attackers. This included both digital and physical techniques, because modern cyber incidents rarely remain limited to technical systems alone. Networks, devices, production sites, buildings, and people all form a single security environment.
No malicious software was installed during the test. No production systems were damaged, and no data was deleted. The purpose was observation, not disruption. Each step was carefully documented so the organization could clearly see where access was possible and which safeguards failed or were missing. The main objective was simple but critical: identify weaknesses before they could be exploited by real attackers. Instead of relying on assumptions or theoretical risk models, the company wanted clear evidence of what would actually work in practice.
What the test revealed was uncomfortable, but valuable. The attackers did not rely on advanced tools or zero-day exploits. They used everyday situations, normal routines, and long-established assumptions. Step by step, these small gaps combined into a realistic and effective attack path. The result was not panic, but awareness. The simulation replaced assumptions with facts and demonstrated how quickly minor oversights can turn into serious exposure.
1. Unattended Computers: Open Doors Without Locks
One of the first issues the testers noticed was surprisingly simple. Several computers inside the bakery were powered on and left unattended. In offices and operational areas, workstations were accessible without any form of automatic screen lock or supervision. From an attacker’s perspective, this is one of the easiest ways to gain access. No hacking skills are required. No passwords need to be cracked. An unlocked computer already provides a trusted entry point into the internal environment.
During the simulation, the testers were able to sit down at these machines and observe what was accessible. Internal systems, shared folders, and active user sessions were within reach. In a real attack, this type of access could be used to copy sensitive information, install malicious tools, or move deeper into the network without raising immediate suspicion.
This situation often develops over time. Employees focus on efficiency and daily routines. Short breaks, quick tasks, or familiar surroundings create a false sense of safety. In production environments especially, computers are often seen as tools, not as security-critical assets.
The test showed that unattended computers are not a minor issue. They are an open door. Once an attacker gains access at this level, technical security controls such as firewalls or antivirus software may no longer provide meaningful protection. The key lesson was clear: security does not fail because of one large mistake. It fails because small, everyday behaviors are overlooked — and quietly become normal.
2. Weak Wi-Fi Security: The Network Was Easier Than Expected
After observing the internal environment, the testers turned their attention to the bakery’s wireless network. What they found was a weak point that often goes unnoticed in everyday operations. The internal Wi-Fi was protected by a simple password. It was short, easy to guess, and had not been changed for a long time. Once the testers obtained access, they were no longer operating from outside the company. They had effectively become part of the internal network.
This change is critical. Many security measures are designed to protect the perimeter of an organization. Firewalls, gateways, and external monitoring tools focus on threats coming from the outside. When an attacker connects to the internal Wi-Fi, these protections often lose much of their effectiveness. From inside the network, the testers were able to see connected devices and internal systems. In a real attack, this access could be used to scan the network, identify vulnerable machines, or intercept unprotected communication. None of this required advanced technical skills. The weak password alone was enough.
Wireless networks are often treated as a convenience feature rather than a security-critical system. Passwords are shared informally, written down, or reused for years. Over time, this turns Wi-Fi access into a silent risk that spreads across departments and shifts. The simulation made one point very clear: a weak Wi-Fi password does not stay a small issue. It removes an important boundary. Once that boundary is gone, the path toward deeper system access becomes much shorter.
Once attackers gain access to the internal Wi-Fi, many perimeter-based security controls lose their effectiveness. This is why basic wireless protection is not a technical detail, but a core security requirement. Practical steps to reduce this risk are outlined in How to Protect Your Business Wi-Fi Network From Hackers
3. Outdated IT Equipment: Known Vulnerabilities, Known Risks
As the simulated attack continued, the testers identified another common issue: several systems were running on outdated hardware and old software versions. These devices were still part of daily operations, but they were no longer receiving regular security updates. This creates a quiet but serious risk. When software is no longer supported, its vulnerabilities are often well known. They are documented, shared, and in many cases already included in automated attack tools. An attacker does not need to discover anything new. They simply need to use what is already available.
During the simulation, the testers were able to identify systems that could potentially be exploited with minimal effort. In a real scenario, outdated devices could be used as entry points or as stepping stones to reach more critical systems. Once compromised, they may allow attackers to move through the network without being noticed.
Outdated equipment is rarely the result of negligence. It is usually the result of long replacement cycles, budget constraints, or the belief that certain systems are “good enough” because they still work. In production environments, stability is often valued more than change. The test showed that functionality alone is not a measure of security. Systems that continue to operate can still expose the entire organization to risk. Over time, outdated IT turns into a weak link — not because it fails, but because it stays unchanged while threats evolve.
Systems that no longer receive security updates quietly increase exposure over time. The risks are often underestimated because these systems continue to function. This dynamic is explained in more detail in When Outdated IT Becomes a Security Risk – What Your Company Needs to Know
4. Physical Security: Social Engineering Still Works
The most revealing part of the simulated attack did not involve computers or networks. It involved people. To test physical security, the ethical hackers entered the bakery while posing as heating inspectors. They wore appropriate work clothing, carried tools, and behaved confidently. No technical trick was required. They simply relied on a familiar situation.
No one asked for official identification. No appointment was verified. The testers were not accompanied by staff members while moving through the building. Within a short time, they were able to access areas that should have been restricted. This type of attack is known as social engineering. It works by exploiting trust, routine, and the natural desire to be helpful. In many organizations, people are trained to notice suspicious emails, but not suspicious behavior in real life.
Once inside, the testers could observe internal processes, locations of equipment, and access paths. They were even able to reach keys and sensitive areas. In a real attack, this level of access could be used to place malicious devices, steal credentials, or prepare future digital attacks. The simulation showed a critical truth: physical security and cybersecurity cannot be separated. If an attacker can walk into a building without resistance, digital security controls may already be compromised. The problem was not careless employees. It was the absence of clear procedures. Without simple rules for verification and access control, trust becomes an unintentional vulnerability.
5. The Real Outcome: Clarity Instead of Damage
The simulated attack ended without disruption to production, without data loss, and without financial damage. No systems were shut down, and no customers were affected. On the surface, nothing had happened. In reality, the company gained something essential: clarity. The simulation showed exactly where the bakery was vulnerable and how different weaknesses could be combined into a realistic attack path. None of the issues alone would have caused immediate concern. Together, they created a situation in which a real attacker could have moved quietly and effectively through the organization.
The most important result was not a list of technical findings. It was a shift in perspective. The company could now see its security from the outside, through the eyes of an attacker. Assumptions were replaced with evidence. Guesswork was replaced with concrete observations. This allowed the bakery to make informed decisions. Instead of reacting to a crisis, the organization could improve its security in a controlled and structured way. Priorities became clear. Risks became measurable. Responsibility could be assigned.
The simulation did not expose a failure. It exposed an opportunity. By identifying weaknesses early, the company avoided the far greater cost of discovering them during a real incident. In cybersecurity, this difference matters. Learning in a safe environment is always cheaper, calmer, and more effective than learning under pressure.
Key Takeaways for Businesses of Any Size
This case reflects a pattern that appears across many industries, regardless of company size or sector. Real cyber incidents rarely begin with advanced malware or highly technical attacks. More often, they start with simple opportunities created by everyday routines, human behavior, and missing basic controls.
The simulation showed that people, processes, and habits play a greater role in security than many organizations expect. Unlocked computers, shared passwords, outdated systems, and unclear access rules are not technical failures. They are operational ones. When these issues are ignored, even strong technical defenses lose their effectiveness.
One of the most common and dangerous assumptions is the belief that a company is not an attractive target. Attackers do not choose victims based on industry labels or brand recognition. They look for easy access, low resistance, and predictable behavior. From this perspective, every organization becomes a potential target. Cybersecurity is not about paranoia or constant fear. It is about awareness. It means understanding how work is actually done inside a business, not how it is described in policies. It means identifying where convenience has replaced caution and where informal habits have become accepted risks.
Simulated attacks are not designed to shame organizations or point fingers at individuals. Their purpose is practical. They give decision-makers a clear and realistic view of what would work in a real attack. This insight creates the opportunity to improve security deliberately and calmly, long before real damage occurs. In the end, prevention is not about perfection. It is about seeing reality clearly — and acting before reality becomes a crisis.
Many of the weaknesses uncovered during this simulation are not isolated issues. They are common warning signs that appear long before a real incident occurs.

Conclusion: Simulated cyberattack case study manufacturing
This simulated cyber attack case study from a manufacturing environment shows a reality many organizations still underestimate. Serious security risks do not appear suddenly or only through highly technical attacks. They develop quietly, through daily routines, informal practices, and gaps that are considered normal over time.
The large bakery company was not targeted because it was careless or unprofessional. It was vulnerable because its operations reflected what is common across many manufacturing companies: a strong focus on production, efficiency, and continuity, while security slowly became secondary.
The simulation proved that attackers do not need advanced tools to cause serious damage. Access was gained through unlocked systems, weak network protection, outdated equipment, and unverified physical access. Each weakness alone seemed manageable. Together, they formed a realistic and effective attack path.
Most importantly, this exercise delivered insight without harm. The company was able to see its security posture clearly and objectively, before facing real consequences. This allowed leadership to shift from assumptions to informed decisions and from reactive thinking to proactive improvement.
For manufacturing organizations, this is the key lesson: cybersecurity is not an IT problem alone. It is an operational responsibility that touches people, processes, and physical environments. Simulated attacks provide the opportunity to understand this reality early — and to strengthen defenses before production, reputation, and trust are put at risk.
Want to Understand How These Attacks Really Begin?
The simulated attack described in this case study follows the same patterns seen in real-world incidents every day. Attacks rarely start with loud alarms or advanced malware. They begin quietly, through small decisions, overlooked habits, and human trust.
These patterns are explored in more depth in Behind the Backdoor – The True Story Behind Modern Hacking Attacks.
The book reveals how modern hackers actually operate — inconspicuously, patiently, and with a strong focus on human behavior. Based on real cases, including well-known ransomware attacks in Germany, it walks through social engineering tactics, weak passwords, USB spoofing, compromised browsers, and overwhelmed IT teams.
Written like a gripping narrative, yet grounded in reality, the book shows how attacks truly unfold and which practical security measures make a real difference. It is not a technical manual and not a fictional thriller, but a realistic look into the grey zone where everyday business life meets modern cybercrime.
