USB 4.0 New Generation of USB With Ultra-Fast Data Transfer Speed

Currently, USB is still the standard for transferring cable-based data, in this latest generation, version 4.0, there is a significant increase compared to the previous version. USB is currently a consortium of several companies consisting of Microsoft, Intel, Apple, HP, and several other technology companies.
Moreover, the maximum speed difference on USB 4.0 reaches 80 Gbps, and if we compare this, it is faster than the speed of Thunderbolt 3 which has a maximum speed of 40 Gbps in Thunderbolt 3.
Advantages of USB 4.0
1. Super Fast Data Transfer Speed
The maximum speed is 80 Gbps with a two-way cable configuration. Data is transmitted in two sets of four bidirectional lines.
2. Thunderbolt Compatible
USB 4.0 is compatible with Thunderbolt devices, version 3 to be exact.
3. Supports DisplayPort 2.0
USB 4.0 through its alternative mode supports DisplayPort 2.0 with 8K resolution at 60 Hz with HDR10 color.
DisplayPort 2.0 can be used at up to 80 Gbps, which is double the amount available for USB data, as it sends all data in one direction (to the monitor) and thus can use all eight data lines at once.
4. Better than PCIe
From the allocation of resources, USB 4.0 is better than Video PCIe. Instead of an alternative mode where another interface takes over the connection, USB 4 devices can use a process called Protocol T tunneling which sends DisplayPort, PCIe, and USB packets simultaneously while allocating bandwidth accordingly.
Intel is also currently working on Thunderbolt 5, which according to the leak will also offer 80 Gbps speeds with a similar physical layer (PHY) connection. Maybe Intel is waiting for USB4 Version 2.0 to be finalized before announcing Thunderbolt 5, so the two can be fully compatible.

How to Improve the Security of Your Home Network Easy

Securing your home network is essential to protect your personal information and devices from cyber threats like hacking, malware, and viruses. In this guide, we will go over some easy steps to improve your home network’s security and keep your data safe.
1. Change the default login credentials
The first step in securing your home network is to change the default login credentials for your router. Most routers come with a default username and password that are easy for hackers to guess. By changing the login credentials to a unique and strong combination of letters, numbers, and symbols, you can make it much harder for hackers to gain access to your network.
To change the login credentials for your router, log into the router’s web interface using the default login credentials. Once you are logged in, look for the “admin” or “security” settings and change the username and password to something unique and hard to guess.
2. Enable WPA2 encryption
Another essential step in securing your home network is to enable WPA2 encryption. WPA2 is the strongest encryption standard currently available for wireless networks and provides an extra layer of security to protect your data from hackers.
To enable WPA2 encryption, log into your router’s web interface and look for the “wireless” settings. Once you are in the wireless settings, look for the option to enable WPA2 encryption and enter a strong password to secure your network.
3. Disable Remote Management
Many routers come with the option to remotely manage the router settings. While this can be convenient, it also poses a security risk as hackers can gain access to your router settings from outside your home.
To disable remote management, log into your router’s web interface and look for the “admin” or “security” settings. Once you are in these settings, look for the option to disable remote management and turn it off.
4. Keep your router firmware up to date
Keeping your router firmware up to date is an important step in securing your home network. Router manufacturers often release updates that fix known security vulnerabilities, so it is important to install these updates as soon as they become available.
To check for updates to your router firmware, log into your router’s web interface and look for the “admin” or “security” settings. Once you are in these settings, look for the option to check for firmware updates and install any updates that are available.
5. Use a VPN
A VPN (Virtual Private Network) is a great way to secure your home network and protect your personal information from hackers. A VPN encrypts all of the data that is sent and received over your network, making it much harder for hackers to intercept your data.
To use a VPN, you will need to sign up for a VPN service and install the VPN software on your devices. Once you have the VPN software installed, you can connect to a VPN server and all of the data that is sent and received over your network will be encrypted.
6. Use a Firewall
A firewall is a security system that monitors and controls incoming and outgoing network traffic. A firewall can help to protect your home network from hackers and malware by blocking incoming traffic that is known to be malicious.
To use a firewall, you can either install a software firewall on your devices or purchase a hardware firewall that can be connected to your router. Once the firewall is set up, it will monitor all incoming and outgoing network traffic and block any traffic that is known to be malicious.
7. Use an Antivirus
An antivirus is a software that can detect and remove malware and viruses from your computer. It can also help to prevent malware and virus.

Malware on Android Steals Facebook Accounts, 300,000 Users Become Victims

Regarding security issues, recently Zimperium through its official page reported that there is a malware campaign that is happening on Android devices, where the device will be infected with a trojan horse and steal Facebook user credentials recently.
According to Zimperium, this threat has been active since 2018 and more generally targets comic and novel readers in Vietnam. The Trojan Horse itself is named “Schoolyard Bully” and is found in various applications that can be downloaded from the Google Play Store including third-party apps with the same title.
So, more or less, for example, like in the picture above, where this application pretends to be an educational application with various books and topics for users to read, including Novels and Comics, but the real purpose of the application is to steal information such as:
- Name on Facebook profile
- ID Facebook
- Facebook email/phone number
- Facebook password
- Device name
- device APIs
- device RAM
This Trojan steals data by opening a fake Facebook login page and injecting malicious javascript code to get user input. And even then, this malware can evade antivirus programs and AI virus detections.
Worse, according to Zimperium, there have been at least 300,000 victims from 71 countries, but the exact number of these countries has not been reported because these malicious applications are still found in third-party app stores.
“Facebook reaches nearly 2.96 billion monthly users and continues to be the number one social media platform. As attackers leverage the Schoolyard Bully Trojan to gain unauthorized access to credentials, they have far more success accessing financial accounts. Nearly 64% of individuals use the same password that was exposed in a previous breach. With the percentage of users recycling passwords, it is no surprise the Schoolyard Bully Trojan has been active for years.” Ungkap Zimperium
Now for Zimperium users, remind that users should read the application reviews before downloading and interacting interactively in it, and also make sure to pay attention to the permission requests requested by the application.
