In recent years, there has been a constant stream of news about cyber attacks targeting major companies and government agencies. Have you ever thought, "It doesn't concern me," or "It's only something that happens to large companies?"
In fact, this idea is extremely dangerous. Cyber attacks are becoming increasingly sophisticated and are no longer just targeting organizations' IT systems.It's creeping into each and every one of our PCs.
In this article, we will thoroughly explain the possibility that your PC could become a "stepping stone" for cyber attacks, the actual type of damage that can occur, and specific measures you can take right now to protect your important data and personal information.
Why your personal computer is a target of cyber attacks
News reports of major cyber attacks may seem like something out of a science fiction movie, but many attacks begin with our everyday, everyday PCs as the "first point of entry."
1. Being exploited as a "stepping stone" to corporate systems
This is one of the most frightening scenarios. Attackers first target a personal computer with poor security. Then, when that computer is connected to a corporate network (for example, when working from home or on a business trip), they use that personal computer as a stepping stone toAttempts to bypass a company's robust security and infiltrate internal systems
Even if your PC does not contain any important information, as long as it is connected to a company's system, you could unknowingly become a part of a massive cyber attack.
2. Your information is targeted
Even if they aren't directly a stepping stone to a company, there are many reasons why personal computers are targeted.
- Personal Information: Credit card information, online banking ID and password, social media account information, etc.
- Financial motives: Encryption of data by ransomware (a virus that demands a ransom) and theft of cryptocurrency wallets.
Main methods and damage of modern cyber attacks
Cyber attacks are evolving every day, but there are several main methods and patterns of damage they cause.
1. Ransomware
- MethodIt will encrypt files on your PC and on any connected network drives, rendering them unusable, and then demand that you pay money to restore them.
- damage: All data, from important photos and work documents to core corporate systems, can become unusable. This is the most damaging attack method in recent years.
2. Phishing scams
- Method: Fake emails and websites pretending to be from major companies, banks, or public institutions will try to get you to enter your ID, password, credit card information, etc.
- damage: Fraudulent use of online banking, theft of credit card information, hijacking of social media accounts, etc.
3. Malware infection (virus, spyware, etc.)
- MethodMalicious programs can get onto your PC by visiting suspicious websites, downloading malicious files, or installing fake software.
- damage: Your PC may slow down, your personal information may be stolen, your PC may be remotely controlled, fraudulent advertisements may be displayed, etc.
You can do it now! Specific measures to protect your PC
Some of you may be worried, "If it's so dangerous, what should I do?" But don't worry. By taking the following precautions on a daily basis, you can protect your PC from most cyber attacks.
Solution 1: Keep your OS and software up to date
OS and software updates contain patches for security weaknesses (vulnerabilities), and if these patches are not applied, your system will become an easy target for attacks that target known vulnerabilities.
- Windows Update: Apply the latest updates regularly.
- Don't use older versions of Windows: When support for an OS ends, such as the end of support for Windows 10, security updates will no longer be provided, which can be very dangerous.
Countermeasure 2: Keep security features "on"
Windows comes with powerful security features built in. By enabling these features, the OS itself will protect your PC from malicious attacks.
Enable Memory Integrity: Checks driver safety and prevents malicious code from loading.
Local Security Authority Protection: Protects critical system processes and prevents tampering.
Kernel-mode hardware-enforced stack protection: Works in conjunction with Memory Integrity to provide even stronger protection for your PC.
Countermeasure 3: Don't open, click, or download anything you don't trust
This is the most basic mindset to protect yourself from cyber attacks.
- Suspicious emails: Never open emails from unknown senders or with strange subjects or content, and do not download any attachments.
- Suspicious sites: Do not visit or click on sites that have many unnatural advertisements or strange URLs.
- Unknown USB memory: Do not insert USB memory sticks of unknown origin into your PC.
Solution 4: Use powerful security software
The standard Windows security software is excellent, but if possible, install paid security software that has a high reputation from a third party and take advantage of its real-time protection and firewall features. It is important to keep it updated to the latest version.

Solution 5: Back up your important data
Even if your data is infected with ransomware and encrypted, having a backup will prevent you from losing your important data. Make sure to back up your data regularly to external storage that is disconnected from the Internet.
