Personal Data Security, Right Now!

In the digital age, every contact we make, every interaction we have, and every digital signal we generate leaves behind a broad data trail—ranging from our search history to our health information. Even if we erase these traces from the visible surface of the digital world, this data continues to exist in the hidden corners of the internet as a digital footprint. Moreover, with the right searches, this information can be brought back to light in a very short time.

Even if we have no intention of disclosing our personal data, the data we unknowingly expose or that is processed by the institutions we are affiliated with becomes not only a valuable resource for companies but also an attractive target for cyber attacks. Therefore, personal data security is not merely a technical issue; it emerges as a fundamental necessity that directly affects individuals’ private lives, financial information, social reputation, and many other critical areas.

In this article, we examine what personal data is, why it must be protected, the consequences of malicious attacks, and landmark legal cases related to personal data theft, analyzing the individual-level impact of data security in the modern world.

What Is Personal Data?

Personal data is defined in the KVKK as “any information relating to an identified or identifiable natural person”; in other words, any information that directly or indirectly identifies a person. This scope is quite broad and often includes details that we share without even realizing it.

Examples of personal data include:

• Name and surname, address, phone number, email
• Identity and passport information
• Health data, biometric data
• Financial status, credit card information
• Location records
• Internet search history, social media activities

In short, all information that enables identifying, tracking, or profiling an individual is considered personal data.

What Is Personal Data and Why Should It Be Protected?

Failure to ensure personal data security can lead to serious negative consequences for individuals in social, economic, and even psychological terms. So, why is the protection of personal data so critical?

1. Privacy of Private Life

Personal data can reveal an individual’s lifestyle, personal preferences, health information, and details related to privacy. Losing control over this information not only constitutes a data breach but can also lead to irreparable consequences and serious harm in a person’s life.

2. Financial Security

The theft of financial information can result in access to banking applications, fraud, taking out loans, and identity theft.

3. Digital Reputation

The compromise of social media data or communication channels such as email can lead to unauthorized access to private correspondence, images, and many personal details.

4. Legal Risks

The unlawful use of personal data may cause individuals to appear as if they are involved in criminal activities without their knowledge. From this perspective, personal data security functions as an important civil defense mechanism that protects individuals’ fundamental rights and freedoms.

Increasing Pressure in the Protection of Personal Data: GDPR and Global Regulations

Starting with the European Union’s GDPR regulation, many countries are making legal frameworks for the protection of personal data increasingly detailed, while also significantly strengthening the sanctions associated with these regulations. These laws place the individual at the center and clearly define:

• How data is collected
• With whom it can be shared
• For what purpose it can be used
• How long it can be stored

Within this scope, personal data is strictly regulated throughout its entire lifecycle—from collection to storage, sharing, and ultimately deletion or destruction.

The main reasons behind the expansion of regulations to become more detailed and comprehensive include individuals unknowingly sharing personal data across various platforms, the material and moral damages caused by data breaches exposing the identities of millions of people, and the need to define standards for the processing and storage of large volumes of data held by major technology companies.

What Can Happen When Personal Data Is Stolen with Malicious Intent?

When personal data falls into the hands of malicious actors, it can result in multi-layered and serious consequences. Individuals may suffer psychological, social, and familial harm; experience financial losses due to negative impacts on their professional lives; and have their reputations severely and irreversibly damaged.

The most common scenarios individuals may directly face include:

1. Identity Theft

Through stolen personal data, attackers may:

• Access individuals’ financial information to take out loans or transfer funds without authorization
• Open fraudulent phone lines
• Gain unauthorized access to online platforms such as e-government, email, and social media accounts

2. Financial Fraud

Unauthorized payments may be made using IBAN or card information. Voice recordings may be used to gain access to banking applications.

3. Blackmail and Threats

Individuals may be subjected to blackmail and threats using private data such as personal photos, messages, or health information.

4. Social Engineering Attacks

Customized fake messages may be delivered via email, SMS, or mobile applications. Personal data may be obtained through methods such as phishing, vishing (deception via phone calls), and smishing (deception via SMS).

5. Digital Reputation Attacks

Fake accounts may be created using an individual’s name and images, and misleading content may be shared. Such attacks can leave serious and lasting effects on individuals’ personal and professional lives.

Conclusion: Protecting Personal Data Is No Longer an Option, but a Strategic Necessity

The consequences of data breaches affect not only organizations but directly impact individuals. Due to risks such as identity theft, blackmail, financial loss, and reputational damage, personal data security is now regulated with serious sanctions.While artificial intelligence has become one of the most critical defense tools strengthening data security, it has simultaneously evolved into a dual-use technology employed by cyber attackers to create more sophisticated attacks.

While 19 criminal/administrative penalty decisions were issued in 2020, records show that in 2024, more than 16,350 lawsuits were filed against organizations in Turkey regarding data breaches. The most important reasons for the steady annual increase in the number of lawsuits include the rapid acceleration of digitalization, the growing monetary and intrinsic value of personal data, increased awareness of individual rights, and the tightening of institutional audits under the KVKK.
