Various forms of cybercrime continue to lurk the rapid internet technology that has made it easier for our daily lives. One of them is the cryptojacking attacks, which we deserve to be aware of since its reporting cases are increasing.
Tips to Protect your Device from Cryptojacking Attacks
A cryptojacking attack means smuggling malware into computers and other media devices and then hijacking computer processing power to do crypto mining. The perpetrators of this cryptojacking attack target media devices and Internet of Things devices that are not safe for cryptomining.
The perpetrators of cryptojacking attacks use a powerful GPU to decode and transcode content in high-resolution formats.
They target a lot of media devices because despite using a powerful GPU, these devices are less secure. Especially because these devices tend to always be turned on, there is a lot of downtime that can be exploited without detection.
” Cryptojacking has become a growing concern. Cybercriminals are not satisfied with the availability of vulnerable servers and PCs to hijack to mine their favorite cryptocurrency.
Cryptojacking attacks need to be considered more because it is predicted that there will be an explosion in the Internet of Things (IoT) that will connect up to 20.4 billion devices globally by 2020. This means that more electronic devices at home are connected to the network or the internet, which can open room for cryptojacking crime.
Fortinet recently shared three tips that we can apply to avoid cryptojacking attacks or other cybersecurity. Let’s listen, Gizmo lovers!
1. Learn & Discover Home Networks
With more and more portable IoTs and other devices installed or used by family members and friends visiting our homes, it may be difficult to know exactly what is in our home network at any given time. It’s even harder to control what they are allowed to do.
There are a number of security tools on the market today that are designed for homes that can identify devices that want to be connected to the internet through our Wi-Fi network. Many of these tools can be easily configured to give them access to our guest network.
On the other hand, we can limit and monitor the type of traffic they produce, applications and home resources they can access, the amount of time they can be connected online and the places on the internet that are allowed to connect.
2. Implement a Segmented Network
Ensure that unauthorized visitors and devices are connected to the guest network while important resources, such as financial data, must be isolated from the entire network. To be more specific, something like this can be done:
- Buy a separate wireless access point to separate things like game systems and IoT devices from PCs and laptops.
- Set up a wireless guest network for new visitors or devices. Most access points allow us to restrict access, manage things, such as firewalls and monitor visitor behavior.
- To protect our important resources, consider buying separate specialized devices that are only used for things, such as online banking. We can also set up separate virtual devices on a laptop or PC for online banking.
- As much as possible, keep our work and personal devices separate. Set up a separate connection to work, only connect through a VPN tunnel, and consider encrypting sensitive data that runs back and forth between our home and company networks.
3. Protect All Critical Devices & Perform Regular Updates
Keep a list of all important devices and applications on our network, including the manufacturer. Set up a regular weekly time to check for updates for physical and virtual devices, operating systems, applications, and browsers.
Turn on the firewall, use a good password and change it every three to six months, and don’t match all passwords for various purposes, especially for our work needs.
