AI Hacking Privacy Crisis

● AI Hacking Privacy Crisis

In the age of AI hacking, personal data leaks are no longer an IT issue but a business survival risk

This article organizes in one place the real reasons recent personal data leak incidents keep repeating, how AI is changing the hacking industry, what responsibilities CEOs and companies will bear under the revised Personal Information Protection Act, and the security checklist small and medium-sized businesses should inspect right away.
In particular, while many news reports end with “it got breached again,” here we will examine from a management perspective why the same company gets hacked again, why banning AI is actually even riskier, and why security investment ultimately leads to cost reduction.

1. The biggest reason personal data leak incidents keep repeating

Recently, personal data leak incidents have continued at Sogang University, public institutions, telecom companies, retail firms, platform companies, and others.
Many people feel that “only Korea seems to get breached unusually often,” but in reality, large-scale hacking incidents targeting telecom companies, hospitals, and retail firms are also occurring steadily in the United States and Europe.
However, because incidents at domestic companies closely tied to our daily lives are reported more often, they tend to feel more serious in practice.

The problem is that Korean companies have been collecting far too much personal information.
When signing up for overseas services, they often require only an email, name, and payment information, but domestic services often request date of birth, phone number, address, occupation, family relationship, and even sensitive preference information.
The more information collected, the greater the scale of damage when a leak occurs.

An even bigger problem is that many companies keep information from customers who have withdrawn without deleting it.
Customers think, “I withdrew, so my information must have been deleted,” but it often remains in the company’s internal database and is leaked together during a hacking incident.
When this happens at a company that handles sensitive personal information, such as a marriage information service, the impact can go beyond a simple contact leak and put an individual’s entire private life at risk.

2. The reality hidden behind the phrase “an unprecedented hack”

When an incident occurs, companies often explain it by saying, “It was an unprecedented, advanced hack,” or “It was an unavoidable attack.”
Of course, high-level attacks do exist.
But when each incident is examined on the ground, many are caused by failing to follow basic security rules.

Examples include passwords that are too simple, former employees’ accounts still active, ordinary employees being given administrator privileges, or security updates being delayed so vulnerabilities remain exposed.
In other words, it is often not a genius hacker from a movie infiltrating with complex technology, but someone walking in through an open door.

From a corporate risk management perspective, a personal data leak is not merely a technical incident.
It is a management risk that simultaneously triggers a drop in customer trust, lower sales, fines, lawsuits, recovery costs, and brand damage.
As digital transformation accelerates, cybersecurity is becoming not a choice but basic infrastructure for business operations.

3. Revised Personal Information Protection Act: fines and executive responsibility are the core point

The most important change in the direction of the revised Personal Information Protection Act is that the level of punishment is getting stronger.
The core point mentioned in the original text is that the upper limit on fines can rise to as much as 10% of total sales, and the CEO is explicitly designated as the final person responsible.

This change is not just a problem for large corporations.
For small and medium-sized businesses, it can be even more devastating.
For example, if a company with annual sales of 5 billion won is hit with a fine of 10% of sales for a personal data leak, it would have to pay 500 million won.
It is not easy for a small or medium-sized business to even generate 500 million won in operating profit, and that money can disappear in a single incident.

And the fine is not the end.
There are incident investigation costs, legal advisory costs, customer compensation costs, system recovery costs, business interruption losses, and customer churn.
In a situation where the global economic outlook is uncertain and recessionary pressure is increasing, these sudden costs can shake a company’s cash flow in an instant.

4. The reality of security at small and medium-sized businesses: there is a person in charge, but no authority or budget

When asking many SME CEOs, “Do you have a security person in charge?” they often cannot answer right away.
In reality, it is common for a general affairs staff member, an employee who knows a bit about IT, or someone good with computers to effectively serve as the security person in charge.

The problem is that they are not professional security personnel and do not have sufficient authority or budget.
In a survey by the Korea Internet & Security Agency, the share of 500 companies in the Gyeonggi region that answered they had a dedicated information security employee was mentioned as being about 27%.
Conversely, that means more than 70% either have no dedicated personnel or have a very weak structure.

Among companies with sales below 5 billion won, the proportion with no dedicated employee or who do not even know their current status was mentioned as being around 84%.
At this level, SME security is closer to a structural problem than a matter of individual will.

Many CEOs think, “We bought antivirus, so we’re fine,” or “We have a firewall, so we’re safe.”
But security is not something that ends after installing a product once.
Like Windows updates, vulnerabilities keep appearing, patches must keep being applied, and access rights must also be continuously managed.

5. AI has torn down the barrier to entry for hacking

In the past, hacking often involved highly skilled attackers spending a long time finding vulnerabilities and infiltrating systems.
But as the AI trend has changed, the speed and scope of attacks have changed completely.

Now AI can scan system vulnerabilities in large volumes and quickly identify exploitable openings.
Even low-level criminals without advanced hacking skills can use AI tools to attempt attacks far more easily than before.
In other words, the barrier to entry for hacking has fallen.

As in the case mentioned in the video, AI-based security models are quickly finding vulnerabilities, and there are situations where security update items for Windows or major software increase by the hundreds.
Finding vulnerabilities quickly is good for defenders, but at the same time it means attackers can also create attack code more quickly.

In the past, there were fewer people looking for holes, and the pace was slow.
Now AI scans broadly and finds vulnerable spots regardless of whether they belong to a small or large company.
So the idea that “who would hack a small company like ours?” no longer works.

6. Hacking has already been industrialized

These days, hacking is not a one-person operation where a single hacker handles everything.
There are separate groups that search for victim companies, infiltrate with AI, deploy ransomware, and extract money through negotiations.
There are even post-incident response groups that pretend to negotiate with victims and help with recovery.

This structure is almost like a corporate business.
From an attacker’s perspective, a company that has been successfully infiltrated once is the best target for a repeat attack.
That is because they already know the vulnerability, and if that opening has not been closed, they can simply get back in.

This is also why some companies suffer ransomware damage, pay money to recover, and then get infected again a week later.
They restored the files, but they did not block the door the attacker used to get in.
Recovery and security measures are completely different matters.

7. The scariest thing about ransomware is reinfection

When ransomware hits, internal company systems are encrypted and work stops.
Customer deadlines, service operations, payment processing, and accounting tasks can all be halted.

Some companies, desperate to restore operations, pay the attacker and recover the files.
But at that point, the most important thing is to 반드시 find out how the attacker got in and block it.
Otherwise, the same attacker comes back through the same route.

As in the case of a well-known online bookstore, there were cases where service was interrupted by ransomware, recovered, and then problems recurred again.
These incidents repeat not simply because recovery capability is lacking, but because the root cause was not properly removed.

8. The first security questions a CEO should check

The CEO does not need to configure a firewall personally or analyze malware.
But there are questions the CEO must know to ask.

What is the most important data in our company?
Where are customer information, transaction data, source code, blueprints, contracts, and financial information stored?
Who can access that data?
Have former employees’ accounts been deleted?
Are folders or accounts shared with partner companies being managed securely?
Have unnecessary administrator privileges been granted to ordinary employees?
When an incident occurs, who should be reported to and in what order should the response proceed?
Is the backup data actually in a recoverable state?

Security begins with knowing what must be protected.
You cannot protect assets if you do not even know where the important ones are.

9. Access control is far more important than many people think

Many incidents begin not with a sophisticated external hack, but with a failure in internal access management.
Typical examples include former employees’ accounts still active, maintenance vendor accounts left open, or Google Drive sharing settings set to “anyone with the link.”

The entire developer team does not need to see source code, and every employee does not need access to the customer database.
Contracts should be visible only to the relevant department, and financial information should be accessible only to the person in charge and the approver.

Give access sparingly, open it only when necessary, and immediately revoke it when someone leaves the company or changes departments.
Following just this basic rule can reduce a significant number of incidents.

10. Banning AI can actually make things more dangerous

The biggest concern for companies these days is the use of generative AI.
Employees are already using AI services such as ChatGPT, Claude, and Gemini in their work.
Using AI for document summaries, meeting minutes, customer response drafts, and report writing can greatly increase productivity.

The problem is that employees may enter sensitive information such as customer data, full contract texts, undisclosed financial information, source code, blueprints, authentication keys, and passwords as-is.
Once this information goes to an external AI service, it is outside the company’s control.

If companies simply say, “Don’t use AI,” employees are likely to secretly use it with personal accounts, smartphones, or home computers.
In that case, the company has no way of knowing who entered what information.
Not knowing is the most dangerous state.

Therefore, the direction should not be prohibition but the establishment of a safe usage framework.
Companies should introduce enterprise AI and review whether input data is stored, whether it is used for training, where the servers are located, and whether administrator logs can be checked.
In addition, security solutions that trigger warnings when sensitive information is uploaded to AI services can also be considered.

11. Information that should never be entered into AI at work

Original customer personal information
Resident registration numbers, contact information, addresses, and payment information
Full contract texts and transaction terms
Undisclosed financial information and investment plans
Source code and system architecture diagrams
Product blueprints and manufacturing process information
Server access information, passwords, API keys, authentication tokens
Internal personnel evaluation data and salary information

Using AI to improve work productivity is a good thing.
However, it is necessary to remove personal data and trade secrets, and develop the habit of inputting only the necessary parts after anonymizing them.

12. Phishing emails and malicious attachments are still the most common attack routes

Hackers create materials that employees are likely to click with great precision.
To companies that have posted job openings, they send resume files.
To video production companies, they send copyright infringement warning emails.
To accounting staff, they send attachments that look like tax invoices or transaction statements.

If an HR employee opens a malicious resume file, the PC becomes infected, and the attack can spread through the company’s internal network via that PC.
This method is very typical, but it still works well.

That is why security education should not end with a formal once-a-year session.
It must be reinforced repeatedly in elevators, office bulletin boards, company messengers, and monthly meetings.
Basic rules such as “check links from unknown senders before clicking,” “do not open emails if the address looks suspicious,” and “confirm with the security officer before running attachments” actually reduce incidents.

13. A realistic security checklist for SME CEOs

For small and medium-sized businesses short on money and time, it is realistic to start with the steps below.
More important than perfect security is reducing the holes that can be blocked right now.

Step 1: Make a list of core assets
Organize the data that must be protected, such as customer DB, contracts, transaction history, source code, blueprints, and accounting materials.
Step 2: Check storage locations
Confirm whether they are on servers, in the cloud, on employee PCs, on external hard drives, or in shared folders with partner companies.
Step 3: Organize access rights
Allow access only to the people who need it, and immediately clean up former employees’ and outsourced vendors’ accounts.
Step 4: Make security updates a habit
Regularly update Windows, servers, work software, website CMS, and plugins.
Step 5: Test backup and recovery
It is not enough just to make backups.
You must test whether recovery actually works.
Step 6: Apply passwords and multi-factor authentication
Immediately change passwords like 1234, company name, and birthday, and apply multi-factor authentication to administrator accounts.
Step 7: Create an incident response contact chain
Organize the order in which the CEO, responsible staff, external security firm, legal advisor, and reporting agency will be contacted in the event of an incident.
Step 8: Hold a monthly CEO review meeting
Even if the CEO checks the security status only once a month, the organization’s level of alertness changes.

14. Government support programs should also be actively sought out

Small and medium-sized businesses often lack personnel and budget even if they want to do security well.
That is why it is necessary to actively look for free vulnerability assessments, security consulting, and information security support programs provided by the Korea Internet & Security Agency or local governments.

If the CEO takes interest, there are more support programs available than one might think.
However, if government support is limited to one-time aid such as antivirus purchases or equipment installation, there are limits.
That is because security is more important in operation than in product purchase.

Going forward, there is also a need to expand operational cost support so that SMEs can continuously perform security patches, access reviews, log analysis, and incident response drills.
In addition, a way of providing technical and legal support to companies that do not hide incidents and report them quickly is also important.

Security incidents often repeat in similar ways within the same industry.
If one company reports quickly and the case is shared, it can prevent damage to other companies.

15. The most important point that other news often do not mention

Many news reports focus on the scale of personal data leaks, fines, and the number of victims.
But the truly important core point is whether the structure that allows the attacker to get back in remains unchanged.

Ransomware recovery, customer notices, apology statements, and fine responses are all actions after the incident.
But if you do not find the attack route, clean up accounts, patch vulnerabilities, and change the access structure, the same incident will happen again.

Another important point is AI security.
AI is not only a weapon for attackers; it also increases the chance of internal employee mistakes.
The moment an employee puts customer information or a contract into AI for convenience, the company’s confidential management system can collapse.

Therefore, future cybersecurity is not just about “technology to block hackers.”
It must become a management system that includes how employees use AI, where data moves, and how partner company accounts are managed.
This point is also highly likely to be reflected in future corporate competitiveness and investment risk assessments.

16. Security investment is not a cost; it is loss prevention

From a CEO’s perspective, a security budget is always burdensome.
It may seem like it is not an activity that generates revenue, and the immediate visible effect seems small.
But once a security incident happens, losses far greater than the money saved occur.

If you think about a 5 billion won company being hit with a 500 million won fine, the answer becomes clear.
Add recovery costs, legal costs, customer churn, and business interruption, and the actual damage is much larger.

Especially now, as the AI trend and digital transformation accelerate, everyone is a target regardless of company size.
Cybersecurity is no longer just a large-company issue; it is a survival condition for SMEs.

17. What changes if the CEO does this just once a month

The CEO does not need to become a technical expert.
But if the CEO asks the following items just once a month, the company’s security level will definitely change.

What important new data was created this month?
Where is that data stored?
Who can access it?
Have former employees’ and outsourced vendors’ accounts been cleaned up?
Have the latest security updates been completed?
Are backups being made properly, and have recovery tests been performed?
Do employees know what information should not be entered into AI?
Have phishing email drills or security training been conducted?

Security is not a grand project but a repeated habit.
The moment the CEO shows interest, employees also come to see security not as “an annoying task” but as “protecting the company.”

< Summary >

In the age of AI hacking, even criminals without advanced hacking skills can quickly find corporate vulnerabilities.
A personal data leak is not simply an IT incident but a management risk that leads to fines, lawsuits, customer churn, and lower sales.
With the revision of the Personal Information Protection Act, the burden of CEO responsibility and fines is increasing further.
SMEs should first inspect core data locations, access rights, former employees’ accounts, backups, security updates, and AI usage standards.
For AI use, safe management systems are more important than bans.
Security investment is not a cost but an essential investment for business survival and loss prevention.
