5 technology mistakes that make users' devices vulnerable to hackers

Users of technology devices such as smartphones, tablets, laptops, etc. are often confident in the protection capabilities of anti-virus software installed on their devices. In addition, users using strong passwords for applications and security measures such as virtual private networks (VPNs) and firewalls also increase users' confidence against hackers.

However, all of the above solutions cannot completely protect users from increasingly sophisticated cybercrime attacks. Users' technology devices are still at risk of being attacked by hackers if they still maintain the following dangerous habits:

1. Use the same PIN for different apps

Users often do not remember many PINs and have the habit of setting an easy-to-remember PIN for smartphones, computers, online services such as social networks, and even bank accounts. According to security experts, this is a dangerous practice and to protect themselves, users should use different PINs for devices and services. If it is difficult to remember, users can consider using a password manager.

2. Always keep Bluetooth connection on 24/7

Bluetooth is a short-range radio technology that works similarly to Wi-Fi and cellular networks, but performs simpler tasks at a shorter range. Users do not need a cellular signal or network connection to use Bluetooth, and it does not use data.

Like Wi-Fi or other connections, Bluetooth also has many security holes that hackers can exploit to attack. Cybercriminals can be nearby and try to connect to the target device by tricking users, then hack into the user's devices. Therefore, to ensure safety, users should turn off Bluetooth connections when not in use.

3. Not securing your home Wi-Fi network

Many users after installing Wi-Fi in their home often keep the default account and password of the router, but this is a dangerous way, creating conditions for hackers to penetrate and attack the devices connected to that network. Once infiltrated into the Wi-Fi network, hackers can download dangerous files or access illegal websites through the user's router.

They can even turn this network into part of a malware-infected network (Botnet) to launch a larger denial of service attack. Therefore, security experts advise users to create a strong password for their Wi-Fi router.

4. Click unsubscribe when receiving spam

If users receive newsletters or promotional emails from reputable brands, hitting the unsubscribe button will be effective because these companies often follow email marketing regulations.

However, for unwanted spam from unknown senders, tapping unsubscribe can actually make things worse. Users are inadvertently confirming that their email address is active, which can lead to more spam. So, users should be aware of when receiving random emails from unknown senders and mark the email as spam in their email client.

5. Clicking on ads and downloading files from unknown websites

Websites that show pirated content about movies, football or betting are considered to contain many malicious advertisements. According to security experts, cybercriminals often create advertisements, then trick users into clicking on them, causing them to unknowingly download viruses or ransomware.

Therefore, users should avoid clicking on these ads. If you need to find information about the product or content in the ad, you can use a search engine to type and check. This method may be time-consuming, but it is safer.
