Anti-Keyloggers: How They Protect Against Keyloggers

Anti-Keyloggers: How They Protect Against Keyloggers

Keyloggers have been used for over a decade to steal sensitive data from unsuspecting victims. Also known as keystroke loggers, it consists of software or programs that record a victim’s keystrokes. If your computer is infected with a keylogger, a hacker might be able to see everything you type — including the usernames and passwords to all your accounts. However, there are tools available to protect against keyloggers, one of which is an anti-keylogger.

What Is an Anti-Keylogger?

An anti-keylogger, as the name suggests, is a cybersecurity tool that’s designed to detect and/or neutralize keyloggers. A keylogger is a type of software, and like most software, it leaves behind a digital footprint. Anti-keyloggers look for the digital footprints of keyloggers to reveal whether a computer or device is infected with one.

All anti-keyloggers are able to detect keyloggers. They run in the background while scanning files to see if there’s a keylogger present. With that said, some of the more advanced anti-keyloggers are also capable of blocking or even removing keyloggers.

Anti-Keylogger vs Antivirus Software

Antivirus software is also capable of identifying and neutralizing keyloggers. Unfortunately, though, it’s not as effective. Keyloggers generally consist of small and discreet files that are overlooked by most types of antivirus software.

Anti-keyloggers are able to detect all types of keyloggers, including hardware-based keyloggers. Keyloggers can be categorized as either software or hardware based. The most common type, software-based keyloggers consist of software. Hardware-based keyloggers, on the other hand, consist of devices or components — such as USB flash drives — that record keystrokes. You can protect against both software- and hardware-based keyloggers by using an anti-keylogger.

It’s important to note that anti-keyloggers are designed to detect all forms of keystroke logging, including legitimate keystroke logging activities. Not all keystroke logging is performed with malicious intent. Some businesses and individuals use keystroke logging software to create a record of everything they type. If you use keystroke logging software for a legitimate purpose such as this, an anti-keylogger may flag it for removal.

In Conclusion

Keystroke logging is an age-old cyber threat that involves logging a victim’s keystrokes. Whether it’s software or hardware based, though, an anti-keylogger can help defend against this otherwise common cyber threat. Anti-keyloggers work by scanning files in search of the digital footprints left behind from keyloggers. At minimum, an anti-keylogger can reveal whether your computer is infected with a keylogger. Some anti-keyloggers go one step further by blocking or removing detected keyloggers.

Production vs Research Honeypots: What’s the Difference?

Production vs Research Honeypots: What’s the Difference?

Honeypots are a common tool used by cybersecurity professionals. Consisting of data that looks sensitive and valuable but really isn’t, they are used to lure hackers. A hacker may discover the honeypot on a business’s network, after which he or she may attempt to retrieve it. While doing so, the hacker will inadvertently provide the business with information about his or her digital footprint, allowing the business to take appropriate cybersecurity measures to protect against real attacks in the future.

While all honeypots are used to safely lure hackers with fake data, there are two primary types: production and research. So, what’s the difference between a production honeypot and a research honeypot?

What Is a Production Honeypot?

The most common type, a production honeypot is a type of honeypot that’s used to collect cybersecurity-related information within a business’s or organization’s production network. Once deployed, the production honeypot will wait for an attack. If an attack occurs, it may collect data such as originating Internet Protocol (IP) addresses, traffic frequency and volume, directories accessories and more.

Production honeypots are popular among businesses because they are easy to use while revealing essential information about cyber threats and vulnerabilities facing their networks. With that said, production honeypots generally don’t reveal as much information as their research counterparts.

What Is a Research Honeypot?

A research honeypot, on the other hand, is a type of honeypot that’s used to collect information about the specific methods and tactics hackers use. Like production honeypots, they consist of fake data that looks sensitive and valuable to hackers. Research honeypots also collect information about attacks and vulnerabilities.

Research honeypots typically aren’t used by businesses. Rather, they are used by government and research organizations. That’s essentially how they differ from production honeypots. While production honeypots are used within a business’s network, research honeypots are deployed elsewhere — typically on multiple networks or locations.

Research honeypots are also more complex than production honeypots. As a result, they require more work to deploy. Because of their complexity, though, research honeypots provide more information about attacks and vulnerabilities.

Other Types of Honeypots

While most honeypots can be classified as either production or honeypot, there are other subtypes of honeypots. Low-interaction honeypots, for instance, require very few resources to run. High-interaction honeypots, conversely, require a greater amount of resources to run. There are also pure honeypots that operate as standalone software. They don’t require any other apps or software. Instead, pure honeypots can run on their own.

Malvertising: Are The Online Ads You See Legitimate?

Malvertising: Are The Online Ads You See Legitimate?

Since its origins in the 1990s, the internet has been powered by ads. Google, in fact, generates over 70% of its total annual revenue from selling ads. While you’ll undoubtedly encounter ads when using the internet, however, you should be cautious of clicking and interacting with them. Even if an ad looks legitimate, it could be an attempt to trick you into downloading malware.

What Is Malvertising?

The term “malvertising” refers to the use of online ads to serve and deploy malware onto victims’ computers. Since all major ad networks prohibit advertisers from promoting malware, it’s typically performed via code injection. A nefarious advertiser will inject malicious code into an ad network or web page. Therefore, rather than promoting a legitimate business — or a business’s legitimate product or service — the ad will promote malware.

The Dangers of Malvertising

Malvertising is a concern because it can result in a malware infection. Whether you’re using Google, Bing, Facebook or any other high-traffic website, you’ll probably see ads. Many of these online ads are even designed to blend into the surrounding content, meaning you may not be able to distinguish them from other types of digital content. And if you happen to click one of these malvertising-related ads, it could spell disaster for your identity as well as your data. Malvertising is a way for nefarious advertisers to trick you into downloading their malware.

Some nefarious advertisers use malvertising to steal the identities of their victims. They serve keylogger or other data-snooping malware that collects the personal information of their victims. Alternatively, other nefarious advertisers use malvertising to deploy ransomware. Ransomware is a distributing form of malware that locks your data while demanding a payment.

Tips to Protect Against Malvertising

While you can’t prevent nefarious advertisers from using malvertising to promote their malware, there are ways to minimize your risk of becoming a victim. Running anti-virus software, for instance, may identify malvertising-related ads. Assuming your anti-virus software protects against online threats, it may detect or even block these malicious ads.

You can also use an ad blocker to lower your risk of being struck with malvertising-related ads. Ad blockers work by disabling all ads from commonly used ad networks. They aren’t biased towards any particular type of online ad. Rather, they’ll block all ads served from the ad networks used in their database. With an ad blocker, however, both legitimate ads and malvertising-related ads will be removed.

The Benefits of Using a Mesh Wi-Fi Network

Is your business’s Wi-Fi slow or otherwise unreliable? Even if your business doesn’t operate in a tech-related industry, it may still rely on Wi-Fi to perform various online activities. From running sales reports to engaging with clients on social media, you’ll probably connect to your business’s Wi-Fi when performing common online activities such as these. If your business’s Wi-Fi is plagued by slow speeds or frequent outages, though, you may want to set up a mesh Wi-Fi network.

What Is a Mesh Wi-Fi Network

A mesh Wi-Fi network is a type of wireless network that’s characterized by the use of signal-extending nodes. It’s called “mesh” because it supports the use of many nodes. Nodes can be added to or removed from a Wi-Fi network. When a node is added, it will replicate the original signal created by the router. When a node is removed, the additional signal will be lost in that area of the Wi-Fi.

Increased Coverage

You can easily extend the range of coverage offered by your business’s Wi-Fi by switching to a mesh configuration. A router alone isn’t always sufficient. It may offer coverage in the room or area of your business’s office in which it’s used. If a room is a far away from the router, though, you may fail to get Wi-Fi coverage.

Each node in a mesh Wi-Fi network will extend the coverage of your business’s Wi-Fi. Therefore, you can use them to fix “dead” spots. If you don’t have Wi-Fi coverage in a particular room, simply add a mesh node between that the room and the router. The node will replicate the router’s signal so that it doesn’t fade before reaching the room. Rather, the Wi-Fi signal will be strong.

Faster Downloading and Uploading

In some cases, using a mesh Wi-Fi network can lead to faster downloading and uploading times. Slow speeds are often caused by a poor Wi-Fi signal. As the router’s original Wi-Fi signal traverses a long distance, it will degrade. The signal will become weaker and, therefore, only able to support slow downloading and uploading speeds.

If your business frequently experiences slow downloading and uploading speeds over Wi-Fi, using a mesh configuration may help. You just need to place the mesh nodes in the right places. If your Wi-Fi is only slow in a particular area, focus the mesh nodes between that area and the router to speed it up.

What Is a Heatsink and How Does It Work?

What Is a Heatsink and How Does It Work?

Heatsinks are a common component used in modern-day computers. Whether you own a desktop or laptop computer, it probably has a heatsink. Some computers, in fact, have multiple heatsinks. Because they are located on the motherboard, though, you typically won’t see heatsinks — not unless you open up the case. To learn more about heatsinks and why they are such an important component for computers, keep reading.

Overview of Heatsinks

A heatsink is a small metal component that’s designed to absorb heat from an adjacent or underlying component. Most computers have a Central Processing Unit (CPU) and a Graphics Processing Unit (GPU). The CPU is responsible for performing a variety of processing tasks, whereas the GPU is responsible for performing image- and video-related processing tasks.

Both the CPU and GPU produce heat during operation. As these components heat up, the risk of failure increases. A CPU or GPU may become so hot that it melts the component’s respective circuitry. Therefore, computer manufacturers use heatsinks to keep them cool.

How Heatsinks Work

Heatsinks work by absorbing heat from the CPU or GPU to which they are attached. If you open your computer’s case and inspect the CPU or GPU, you should see a square- or rectangular-shaped metal component over it. This is the heatsink, and it’s responsible for drawing heat away from the CPU or GPU.

Most heatsinks consist of fins resembling that of a radiator. As the CPU or GPU warms up, heat will transfer to these fins where it’s released using a fan. A fan is attached over the heatsink to circulate air. The fan runs in reverse, meaning it draws the hot air away from the CPU or GPU. There’s usually another fan located on the motherboard that further pushes the hot air out of the computer case.

Are Heatsinks Really Necessary?

In most cases, heatsinks are an essential component that’s required for a healthy and functional computer. Without a heatsink, a CPU’s or GPU’s temperature may rise to dangerous levels.

Some people assume that heatsinks are only necessary if you plan on overclocking your CPU or GPU. Overclocking does, in fact, increase the amount of heat a CPU or GPU produces. Nonetheless, both CPUs and GPUs can produce enough heat to cause internal damage during normal operation, regardless of whether they are overclocked. A heatsink solves this problem by drawing heat away from the CPU or GPU so that it can safely be released out of the computer case.
