Hestia Control Panel with A2 Hosting
In this tutorial you will be shown how to setup a website server using Ubuntu 20.04 and Hestia Control Panel within A2 Hosting. I have made my move from Linode VPS to A2 Hosting VPS to host my website server.
Now the few reasons I have decided to move my Hestia Control Panel over to A2 Hosting was due to a few issues with Linode servers. I had horrible server performance, however they would move me to less nosey shared VPS servers I would continue to suffer after a few hours. I also believe that Linode’s environment may be suffering from many bot crawls and DDOS attacks on their client base. After performing a live move to A2 Hosting and testing it out for a few days I have noticed increased performance. Pages loaded quicker and there has been less noise on the server from bot crawls and DDOS attacks. … Read the rest

New Windows malware strain creeps quietly past your antivirus
Security researchers have discovered a new malware campaign that uses code signing certificates and other techniques to avoid detection by antivirus software. A recent blog post from Elastic Security, the cybersecurity firm, reveals that its researchers discovered a cluster of malicious activity after reviewing its threat prevention telemetry.
Cybercriminals are getting smarter. They have figured out how to use valid digital certificates to sign their malware, so security programs won’t find them. However, this new campaign from Blister is different. The cybercriminals have created a new kind of loader for the malware. It has been named Blister by researchers because it burns like a blister on the skin, but you will never see it until it is too late.
With the help of valid code signing certificates and other counter-detection measures, these cybercriminals have been running this campaign for the past few months.

Can Someone Spy On You Through Your Webcam or Phone Camera?
Are hackers spying on you through your computer camera and phone camera? Yes, it is true. Your webcam or phone camera can be hacked, which means that the hacker can monitor you and potentially steal your personal information. However, there are ways to prevent or identify the hacking of your webcam and phone camera.
What would a hacker do with a device’s camera?
If you see a camera icon at random, when you know none of your trusted apps are running, your device may be hacked. The good news is that modern devices use a light to indicate whenever the camera has been activated. If you see this light even though you know no app is running, it might be time to back up your data and wipe your device clean.
If a hacker infiltrates your device, they’re probably looking for something specific. But usually they’re after big data, rather … Read the rest

Key Knowledge
- An Intrusion Prevention System (IPS) is a type of engine that identifies malicious traffic by checking the signatures. The signatures contain known traffic patterns or instruction sequences used by malware. This type of signature-based engine can only detect anomalies based on known malicious traffic patterns.
- An Intrusion Detection System (IDS) is a network security technology originally built for detecting vulnerability exploits against a target application or computer. IDS only listens for issues and alerts you and does not take preventative action.
- GeoIP Filtering is a technology that can block web traffic from entire countries, can be an effective way to stop hackers from attacking your business. As the
