The internet is at risk of being merged into small clusters owned by a few individuals. So, many turn to decentralization as a remedy.

You get more privacy when one provider can't control the means of your communication, web hosting, social media access, or other services. A decentralized VPN tests this idea for a secure internet connection.

Unlike traditional centralized VPNs, there is no single entity controlling the servers. Instead, requests are routed through multiple devices. Does this approach work with VPNs, or do you risk exposing your data even more?

Most of us are already immune to the "traditional" phishing attacks via email. The vast majority of them are caught by the algorithms and go straight into the spam folder. Scammers do not rest and instead have switched their focus to social media users.

Impersonating companies and using your profile against you, scammers try to lure your personal information for their benefit in what's called an angler phishing attack. We'll discuss all you need to know to be safe from them.

An international law enforcement team has successfully arrested hundreds of criminals and seized their illegal assets. All thanks to an allegedly encrypted messaging app with data collection backdoors for the FBI.

That's where the name FBI honeypot comes from. But while effective in catching criminals, honeypots raise important privacy and security concerns.

After such a precedent is set, how can anyone be sure he isn't falling for a honey trap even without any criminal intentions?

Once you move out of a country to somewhere else, you lose access to all the location-locked content. For some countries that may not be a big issue, but if you move out of the US, for example, the content offered by every streaming service and many other platforms will change greatly.

A virtual private network (VPN) can help you circumvent the issue entirely. As long as the virtual private network has servers in that particular country, you can access any location-based content.

That’s part of the reason as to why VPNs became so popular – they allow you to access web services and content that otherwise would not be available to you.

NFC (Near-Field Communication) is a short-range wireless technology that allows devices to transmit information over short distances (usually, a few to a dozen centimeters). NFC signals are widely used for small, quick operations such as contactless payments and access control.

It’s built upon the RFID technology and is intended to be more secure. However, NFC security isn’t foolproof either – there’s plenty of ways for various people to abuse the system. Since NFC signals are used for important operations (e.g., contactless payments), knowing how to avoid such situations is vital.

MAC flooding is a network attack that intends to overwhelm a switch (a device that directs data packets to specific MAC addresses), causing it to enter a fail-safe mode. A network switch, when overwhelmed, enters an “open” mode where all information is sent to every port to avoid taking down the network.

Since all data is transmitted to every MAC address, the security of a network is compromised. Normally, a switch would only send data to specific ports and addresses. In the fail-safe mode, port security is compromised as all information is transmitted to every port.
