Cybersecurity journalist Graham Cluley, writing for Bitdefender's Hot for Security blog, recently covered the arrest of an alleged French hacker known online as HexDex. The suspect, reportedly 21 years old, was accused by French authorities of being linked to nearly 100 breaches affecting public institutions, education systems, trade unions, and other organizations across France.
According to reports, some of the compromised systems allegedly exposed sensitive personal information including names, contact details, employee records, and other private data. Authorities believe some of that stolen information was later sold or shared online.
When people read a story like this, they often imagine some elite hacker operating at a level most people could never reach. The common image is someone writing sophisticated malware, discovering rare zero-day vulnerabilities, and breaking into highly protected systems with cutting-edge techniques.
The reality is often far less glamorous.
A lot of breaches happen because someone kept looking long enough to find systems that were never properly secured in the first place.
Hacking Used to Require Years of Real Technical Development
Years ago, breaking into complex systems required a much higher barrier to entry. Someone interested in offensive security had to spend years developing real technical skills.
They needed to understand networking, operating systems, web applications, databases, authentication systems, scripting, programming logic, privilege escalation, reconnaissance techniques, and infrastructure behavior.
Finding vulnerabilities was slow and frustrating work. You had to spend countless hours reading documentation, testing applications manually, reviewing traffic, understanding how systems communicated, and figuring out where weaknesses existed.
Anyone who has worked in offensive security knows vulnerability discovery is rarely glamorous. Most of the process involves patience. You spend hours researching targets, testing assumptions, hitting dead ends, reviewing strange responses, and trying again.
That part has not changed. Real vulnerability research still requires time.
AI Is Changing the Speed of Offensive Work
What has changed is how quickly people can move.
Artificial intelligence is now accelerating parts of offensive security work in ways many organizations still underestimate. It can help people write scripts faster, understand unfamiliar code, summarize documentation, identify potential weaknesses, automate repetitive tasks, and speed up reconnaissance.
AI does not magically transform someone into an elite hacker overnight. It does not replace deep technical expertise.
But it absolutely helps reduce friction.
Someone who previously would have spent days figuring out how to write a script, understand a technology stack, or troubleshoot code can now move significantly faster.
That changes the threat landscape. Organizations can no longer assume that technical complexity alone will protect them because the learning curve is becoming smaller for motivated attackers.
Persistence Is Becoming One of the Biggest Threats
This is where the HexDex case becomes especially interesting.
He clearly had technical skills. Nobody accidentally gets connected to that many breaches.
But what stands out even more is persistence.
If someone spends 10 to 12 hours every day scanning targets, researching infrastructure, testing exposed services, looking through public records, checking old domains, and searching for weak points, they will eventually find opportunities if organizations leave enough mistakes behind.
Finding vulnerabilities often requires spending long periods simply poking around systems and understanding how things work. Most attempts fail. Many leads go nowhere.
But determined people keep going. And eventually, patience creates results.
Attackers do not need every door to be open. They need one forgotten door that nobody checked.
Graham Cluley Is Right: Cybersecurity Is Not Only About APTs
Graham Cluley is right to highlight cases like this because they expose a major misunderstanding in the industry.
Cybersecurity conversations often focus heavily on advanced persistent threats, nation-state actors, sophisticated malware groups, and highly advanced hackers.
Those threats absolutely exist. But they are not the entire threat landscape.
A huge number of breaches happen because of persistent individuals who are simply willing to spend the time necessary to accomplish a goal. They may not have intelligence agency resources. They may not be developing advanced exploits. But they have patience.
And patience becomes dangerous when companies leave weak passwords, exposed infrastructure, outdated systems, poor access controls, and unpatched vulnerabilities sitting online.
Sometimes the biggest threat is not the most advanced attacker. It is the person who refuses to stop looking.
Many of These Breaches Likely Started With Basic Mistakes
The uncomfortable truth is that many organizations still struggle with basic security hygiene.
Old servers remain online. Unused accounts stay active. Critical patches get delayed. Cloud storage gets misconfigured. Administrative panels stay publicly exposed. Logging is weak. Asset inventories are incomplete.
These are the exact types of weaknesses persistent attackers love finding.
The HexDex case appears to show someone moving quickly through multiple organizations and taking advantage of repeated mistakes. In many ways, it looked like a speedrun of weak security practices. That should deeply concern defenders.
Public Sector Breaches Create Long-Term Consequences
Some of the reported victims were tied to public institutions, which makes this situation even more serious.
When public systems are breached, victims often cannot simply stop using the service or move to another provider. Governments, schools, and public institutions often store identity records, employment data, addresses, legal documentation, and personal information people are required to provide.
When that data is exposed, the consequences can last for years. Victims may face identity theft, phishing campaigns, fraud attempts, impersonation attacks, and privacy violations long after the original breach.
The damage continues long after an arrest is made.
Organizations Need to Adapt to This New Reality
The cybersecurity environment is changing quickly.
Attackers have more automation. They have more public tools. They have faster learning resources. And now they have AI assistance.
Meanwhile, many organizations are still operating like it is 2015.
Companies and institutions need stronger visibility into their infrastructure. They need faster patching cycles, better authentication controls, stronger monitoring, better asset management, and more frequent security testing.
The basics are no longer optional. Because attackers are becoming faster at finding organizations that ignore them.
The Real Takeaway
This story is bigger than one arrest.
It highlights how modern cybercrime often works. Yes, technical skill still matters. But persistence, patience, automation, and AI are helping close the gap faster than many organizations realize.
Graham Cluley's reporting through Bitdefender highlights something defenders should take seriously: the field is not only filled with elite hackers and APT groups. It is also filled with determined individuals willing to spend endless hours trying to accomplish a goal.
And if organizations fail to secure the basics, someone persistent enough will eventually find their way in.
