Everyone has tried to secretly shop for a birthday gift online or look up some weird thing that shouldn’t remain on anyone’s browsing history. To do that without leaving a trail, you probably decided to go Incognito. If not, we’ll explain to you why you should.

Here you will learn how to open a new Incognito window on all major browsers. We’ll show you the exact steps to take, explain that Incognito mode really does, and give you some tips for better privacy.

Denial of Service (DoS) attacks disrupt access to networks or services. But a more harmful variant is pDoS, or Permanent Denial of Service. Unlike other DDoS attacks that flood the target with huge amounts of internet traffic, a pDoS attack can permanently damage hardware.

Understanding Permanent Denial of Service is crucial since these types of attacks target the hardware layer, not just software. In this blog post, you will learn how a pDoS attack works and how to prevent long-term damage and costly recovery.

When we carry our phones every day, they get exposed to multiple Wi-Fi connections and public networks. Such connection points are often a fertile ground for sneakers and cybercriminals, who aim to intercept your traffic. To protect yourself from such threats, you need a VPN on your iPhone. Find out what it is and how to get it.

Computers talk with each other in numbers and humans in words. That's a simplification, of course, but it gives us a good idea of what DNS servers do — translate words of domain names (cometvpn.com) into numbers of IP addresses (172.67.201.66).

A DNS server can be a privacy hazard as it has to be informed about every website you visit. A private DNS solves this problem by allowing you to use a DNS provider of your choice, possibly with encryption. We explain what private DNS is and how to set it up below.

We’re all familiar with the pain of sudden internet connection problems, instability, and the constant website crashes. And while this could just be an innocent connection loss, it could also be a sign of an IP fragmentation attack.

Although a lesser-known threat, it’s a type of cyber attack that exploits the way internet protocols handle data transmission to evade firewalls, disrupt services, and infiltrate networks undetected.

If successful, a slowed internet would be the least of your worries – there would also be a risk of major application crashes, and worst still, malicious and unauthorized data breaches. That’s why it’s important to be informed and know how to protect your device properly.

Screen hacking is a new type of attack that injects fake touchpoints on a touchscreen by using electromagnetic interference EMI. A hacked screen can be used to perform any action on the device, including opening browsers, sending messages, or installing software.

Hackers use dedicated devices to send signals to your touchscreen that mimic the same signal sent when the screen is being touched. Luckily, it’s currently impossible to do that from a long distance, so the person has to be within a few meters of you, making it easier to understand what’s going on.
