Online banking is a risky business because you have to enter your login credentials and credit card info on the web. If you’re directly connected to the Internet, you might accidentally leak them and compromise your data. But you can use a VPN to stay safe.

A virtual private network creates a secure tunnel and uses it to isolate your data traffic from the public web, all thanks to encryption. In case of a man-in-the-middle attack, a hacker might obtain your data but can’t unscramble it.

Should you use a VPN for online banking?

Yes, you should definitely use a VPN for online banking since it makes you safer on the Internet.

Although most banks are doing the best they can to make you feel as safe as possible when making online transactions, sometimes they fail.

Internet banking is particularly dangerous during the COVID-19 pandemic when most people stay home and pay taxes or shop exclusively online. But a VPN helps a lot.

Here are some legit reasons why you need a VPN for online banking:

Keeps you safe from cybercriminals when using public Wi-Fi hotspots.

Amps up your security level when traveling and connecting to the airport, hotel, or restaurant Wi-Fi.

Shields your mobile apps since they’re most vulnerable to hacker attacks.

Adds an extra layer of security to your home network and protects your router.

Excellent in combination with HTTPS websites.

How to use a VPN for safe Internet banking 1. Say no to free VPN

A VPN is only as good as its privacy policy. If you stumble upon a legit service with a strict, no-logging policy, that’s great! But you can’t trust a free VPN with your data. In fact, it’s safer to use online banking without a free VPN.

Even if the VPN provider won’t collect your data, there are still dangers since free mobile apps are usually ad-supported. Any ad or banner to a third-party website is a door left open for malware injections. But a premium VPN is worth it.

2. Don’t use VPN servers from other countries

If your bank is actually doing a good job and monitoring your account for any suspicious activity, it will flag and freeze it if you try to connect from another country. Plus, it will probably call you soon to let you know.

Clearing this issue with the bank BEFORE won’t do you any good if you keep connecting to various countries through the VPN. And it’s never a wise idea to ask your bank to stop doing this, in case an authorized user actually attempts this.

Instead, limit your VPN server options inside your own country. It doesn’t matter which one you use, anyway, since all bring the same level of security.

3. Set the VPN’s security settings to the max

VPNs have numerous benefits, like circumventing geoblocks and unlocking streaming services like Netflix. But, when it comes to online banking, what you’re looking for is the highest level of security.

Set your VPN service to use a highly secure protocol, like OpenVPN with 256-bit military-grade encryption, WireGuard, or SSTP. Keep in mind that more encryption means a slower connection.

If you have trouble maintaining your Internet connection stable over VPN, dial it down a notch until you find the balance between encryption and speed. Whatever you do, never use a VPN over PPTP or L2TP because they provide low security.

Besides encryption, enable the app’s kill switch, activate its built-in ad and malware blocker, and switch to its private DNS servers, depending on what features are supported by the VPN service (unlike encryption, they won’t slow you down).

4. Don’t use weak passwords or turn off 2FA

A VPN can’t keep your online banking account safe from illegal logins, so don’t compromise when it comes to passwords and two-factor authentication. Set a strong lengthy password made out of a random combination of uppercase and lowercase letters, numbers, and symbols (or use a password generator).

If you have trouble keeping up with your passwords, use a reliable password manager to keep track of them, especially since it’s recommended to change them often. Furthermore, check if you have two-factor authentication enabled.

5. Use a secure browser

Unless you use a mobile app to access your banking account, consider switching to a secure web browser for online banking. You don’t have to get rid of the current browser if you’re fond of it since you can install a new one to use for banking purposes, such as Tor Browser, Brave, or Firefox.

6. Use security-focused browser addons

If you want to continue using your current web browser, even if it’s unsafe, you can amp up its security level by turning to security-focused extensions like DuckDuckGo Privacy Essentials, Ghostery, Privacy Badger or HTTPS Everywhere.

What’s the best VPN for safe online banking?

Made by Kape Technologies, Private Internet Access (PIA) is the top-ranked VPN for Internet banking, thanks to its excellent security features. It uses OpenVPN with up to 256-bit military-grade encryption to redirect your entire network traffic through VPN.

How To Check If A File Is Safe For Downloading

The internet has many websites that claim they have the correct file. Most of the time, you have to open the file to confirm the file is safe. And by that time, it may be too late to protect your PC from malware and virus programs.

This type of scenario is common on many websites. The pop-up may take you to a shady website where downloading files puts your PC at risk. If a pop-up appears, it is best to close it right away and try again.

Torrents is a highly popular P2P file-sharing website. Typically files found in torrent sites are copyrighted or commercial material. Most of them are provided by anonymous sources and there is no telling if the file is tampered with.

Applications downloaded from torrents may or may not be the applications you want. There is no incentive to provide the right file for downloading as a torrent. You may be downloading a malware program or a virus on your PC.

Apart from the legal aspect, torrents are highly unsafe for downloading files. You should avoid downloading torrents from unknown users. To confirm a file is safe, you have to download it from a known, trusted source.

HyperText Transfer Protocol is the backbone of the internet. Internet browsing and downloading works in a stream of HTTP requests and responses. Simply put, HTTPS is encrypted HTTP. Secure encryption ensures that the website you are visiting is trusted.

To protect yourself from download threats, always perform a safety check before downloading. Continue reading below to know some of the regular safety approaches to download a file.

Depending on the type of Antivirus you have, you can do a file check before or after performing a download.

Know your file formats. Whether a new or old Windows user, always make sure to enable file extensions in Explorer by default. It’s a security hazard that they turn it off by default. Turn it on from the explorer File options .

Many websites such as Fileinfo lets you search from their large database of file extensions. File extensions are three or four characters long. They are the last characters after the period (.) shown in the file name.

Note that these two factors are not complete indications of the validity of a file. They only tell you whether a file is trusted and downloaded by other users.

Md5 sum file hash is a popular means of verifying any file. Md5 algorithm takes a file and generates a 128 character unique hash. This way, if the download file is tampered with, the resulting hash would be different. 

Many download websites offer md5 hash along with the download link. With it, you can verify if the file you get is the same as the one they provide. This is a good approach if you trust the file provider to let you download your file safely.

Note that you would still have to download the file first before you can start checking it. You should open the file only after you’re sure it’s safe to do so.

Note down the file hash next to the download link.

Go to any online md5 hash checker tool.

Upload the file and let the tool generate hash for you.

Compare the file hashes together to make sure they are the same.

Windows Sandbox is a special feature provided by Microsoft as a testing ground. Even if you manage to break your sandboxed Windows, it won’t have any impact on your base Windows at all. So, it is a good idea to test all your suspicious download links in a sandbox environment.

Note that the feature is available in Pro and Enterprise versions only. Other Windows users can use a virtual box or VMware image instead.

Forums are the place to confirm the validity of any file. Most of the download websites provide a discussion forum for site visitors. Anyone can register for an account in the discussion forum and post their questions. Other experienced users can write answers and even upvote questions and answers.

Some users even make time to point you to the correct file that you’d need to download. Since anyone can post on the forums, you still need to be careful in believing what you read. I always recommend taking the file forums with a large pinch of salt.

Virustotal is a reliable site to perform safety checks. It has two modes, the first file mode and the second is link mode. File mode allows you to upload a file and verify if it’s safe. Link mode allows you to run a safety check even before downloading the file.

Virustotal runs virus scans against a database of multiple vendors. It then reports if the file passed all safety checks. For now, we will stick to using link mode.

To disable the automatic downloading of files, follow these steps.

Chrome Firefox Safari

Go to the Safari menu and select Preferences.

Under the General tab, select a File download location.

Select Ask for each download.

Under the General tab, select a File download location.

Select Ask for each download.

How Safe Is Two Factor Authentication?

How Safe Is Two Factor Authentication? How Can A Hacker Bypass Two-Factor Authentication? SIM Swapping

SIM Swapping is an attack in which a hacker can impersonate you and then he convinces an employee at a carrier to switch the phone service that you have to that of a carrier. Once that happens, the hacker has access to all your messages. Do have a look at two of these instances –

The phone number associated with the account was compromised due to a security oversight by the mobile provider. This allowed an unauthorized person to compose and send tweets via text message from the phone number. That issue is now resolved.

In another instance, a hacker was able to hack into a user’s text for just a matter of USD 16. Here the case was different from regular SIM swapping. Instead, the hacker utilized a service that is intended to help businesses do mass messaging and SMS marketing. These are the whereabouts of the case.

Social Engineering

In a second way, the hacker might send you a phishing mail or rope you in a legit-looking website. Once you log-in on this website, the hacker gets access to your credentials which he then uses on a real website, after which the real website sends you a code. Once you enter the code on the fake website, the hacker can bypass the two-factor authentication.

Now, that we have stated the problem, let’s have a look at some of the probable ways to prevent ourselves. Read on!

Is Two Factor Authentication Safe? Add An Extra Layer Of Protection Too

Kudos if you have enabled two-factor authentication, but consider arming yourself with options the likes of which are mentioned below –


You should invest in a quality VPN that can encrypt data traffic and even helps in securing browsing sessions. It is even able to evade session hijacking and phishing attacks as well. Here are some of the best VPNs available. In any case, if the 2-factor authentication has been invaded because of some social engineering attack, a VPN will for sure act as a guard against it.

Looking for a VPN for your PC, you can consider investing in Systweak VPN. Here are some of the features –

4500+ servers across 200+ locations spread in 53+ countries

AES-256 military-grade security

Kill switch that drops the connection as soon as VPN drops

No DNS leaks

IKev2 and Open VPN protocols

30 days money-back guarantee

Here’s our comprehensive review of Systweak VPN

Price: US$ 71.40 yearly or US$ 9.95 per month

Operating System: Windows 10/8.1/8/7

Recommended By VPN Mentor

Physical Security Keys

If you can get your hands on physical security keys, there’s nothing like it. These prove to be a more secure second step. Hardware-based keys have several passwords stored in them and as one of their features are also able to easily discern between real and fake websites. They are positively more secure and stronger than software or SMS-based options.

Use A Password Manager

Consider this – your smartphone is lost or stolen and now it is in the hands of a probable hacker, who can easily look into the code being sent. Scary, right?

If you use a password manager like LastPass, each time it will generate a very strong password because of which the hacker will have a hard time bypassing, say, your authenticator app. Secondly, a password manager like LastPass eliminates the need to manually typing in the password.

Is Orbot A Good Vpn? Check Our Honest Review

Is Orbot a good VPN? Check our honest review




Orbot is a nifty security/privacy application that can keep your mobile communications private while you’re online.

You can use Orbot exclusively on Android devices, but there are also some ways to run it on Windows 10 PCs. Spoiler alert: it involves using emulators.

Check out our VPN Section for more guides on how to protect your digital life.

Visit our Security Hub to discover more about maintaining your online security.

Fortect is a tool that does not simply cleans up your PC, but has a repository with several millions of Windows System files stored in their initial version. When your PC encounters a problem, Fortect will fix it for you, by replacing bad files with fresh versions. To fix your current PC issue, here are the steps you need to take:

Orbot is a nifty security/privacy application that can keep your mobile communications private while you’re online. It’s based on Tor, but it’s only available for Android phones.

As you probably figured it out already, you can’t exactly use it on Windows 10. Tor and its browser are enough protection and basically offer the same thing for your Windows 10 PC.

Many take Orbot for a dedicated VPN service, which is not exactly true. While Orbot does offer some VPN features, it functions after a somewhat different set of rules.

Did we mention that it’s entirely free to use?

Is Orbot a VPN?

Long story short, no, Orbot is not a VPN for your Android phone. What this project manages to do instead is bring Tor functionality to Android phones. It’s optimized for these devices, so you can rest assured that it’s not just some port.

Orbot lets you connect to the Internet in a secure, private manner. You’re maybe thinking: right, but that’s the same thing a VPN does, so how is Orbot any different? Well, the truth is that this app has the best of both proxy servers and VPNs.

Proxy vs. VPN

Proxy servers let you access certain websites and services on the Internet by offering you a gateway. A VPN establishes a secure tunnel to any server in its network.

Both proxies and VPNs mask your IP address, but proxy servers are generally less secure due to a lack of encryption. A VPN encrypts your traffic, but it can be a bit slower than a proxy.

Orbot uses Tor to encrypt your traffic by redirecting it through various nodes around the world. The nodes are usually other Tor users, but there’s also a chance you can bounce through an exit relay hosted on a dedicated machine.

Long story short, Orbot can be rather deemed as Tor for Android phones with added VPN functionality (includes a VPN mode).

What is VPN mode in Orbot?

As we’ve briefly mentioned above, this app encompasses a VPN mode. Upon closer inspection, you may notice that it acts exactly like a VPN.

It even asks you for permission to manage your connection, just like any other Android VPN service does.

However, Orbot has a bunch of extra features that regular VPNs may lack. For instance, it’s widely known that many websites have VPN filters, which are used to detect and block VPN traffic. One such website is the US version of Netflix.

How good is Orbot VPN?

Considering that it’s based on Tor, Orbot’s VPN can’t be blocked by websites as easily. Your connection will bounce through several nodes until finally reaching the website, which makes it harder to detect and block.

Furthermore, your traffic will be both encrypted and dispersed throughout all the nodes on your connection. This makes it tenfold harder to decrypt traffic, given that it’s not all in the same place.

Last, but not least, Orbot’s VPN feature lets you enable it only for certain apps on your phone. It kind of works like split tunneling, letting you choose which apps’ traffic will be encrypted.

How to use Orbot VPN

1. Install it on your device

Visit the product page on Google Play

Hit the Install button

Wait for the installation to come to an end

Hit the Open button to launch the app

2. Launch Orbot

3. Connect to a server

4. Toggle VPN mode

It’s worth mentioning that you can select the apps for which Orbot will encrypt traffic. Selecting no apps (by default, no apps are selected) will enable a system-wide VPN.

Additionally, we’ve found some hints that the system-wide VPN only works on rooted phones. However, we’ve tested it on a non-rooted phone and it seems to work just fine.

5. Configure Orbot

Note that from an accessibility standpoint, Orbot can be easily configured, as most of the customization options work on a disable/enable model.

However, you should refrain from bringing any changes to the default configuration unless you really know what you’re doing. Otherwise, you may break Orbot’s security and even its functionality.

6. Bonus: for Samsung devices

Reportedly, there’s an app running on Samsung devices that listens to port 9050, which Orbot uses by default. You can either locate the apps that are listening on that port (use third-party apps such as Netstat), force stop them and disable them.

However, it’s far easier to just change Orbot’s default Tor SOCKS port from the app.

How to use Orbot VPN on Windows 10

As we’ve clearly mentioned above, Orbot is Android-exclusive. Thus, not only is the app only available for Android, but it’s also optimized for these devices alone.

In conclusion, you can’t run Orbot on your Windows 10 PC natively, so you’ll have to improvise.

Although you can either use a regular VPN or Tor on Windows to the same effect as Orbot, if you’re stubborn you’ll need an Android emulator such as BlueStacks or NoxPlayer.

Once you have the emulator installed on your PC, deploy the app on it as we’ve described above.

Apparently, the app works without any major issues on Android emulators. However, it won’t be able to hide any traffic from outside the emulator. Furthermore, it may not be as secure as installing and running it on an Android device.

Final thoughts on using Orbot as a VPN

All things considered, if you want a private, secure VPN on your Android device, Orbot is a good place to start. It basically brings all of Tor’s functionality on your Android phone, with added capabilities.

If you plan on using Orbot on your Windows 10 PC, it might be too much hassle. Since the app is Android-exclusive, you’ll need an emulator to get things running, and you might even notice certain bugs during the app’s runtime.

Your connection is not secure – websites you visit can find out your details:

8 Safe Free Software Download Sites For Windows

There’s a lot of free Windows software download sites, but are they safe? Every time you download something, there’s a possibility that you’re downloading malware or viruses. Sure, you’ve got the best antivirus app, but there’s no sense making it do work that it doesn’t have to do. 

In this article, we’ll talk about how you can check whether a download is safe and we’ll also mention a couple of our favorite sites to download free software for Windows.

Table of Contents

Are Free Software Download Sites Safe?

There are businesses that rank how safe sites are. One of the most popular sites for this is WOT or Web of Trust. WOT rates sites based on community ratings, reviews, and their own machine learning algorithms. There are WOT plugins for Chrome, Firefox, and Opera browsers. If you have the plugin installed, you can check the download site.

You can also check the site before you go to it. Go to Virus Total and enter the web address of the site. It’ll check with a bunch of other sites that track reputations and viruses and lets you know if the site is safe.

That does not mean that what you download from the site has no malware or viruses. There are a couple of ways to test the download. 

Use a sandboxed web browser like Sandboxie to download it. In the sandboxed web browser, go to Virus Total and submit the download for testing.

Download the program inside a virtual machine and test it there.

Safe And Free Software Download Sites for Windows

To compile this list, we researched the sites on WOT, VirusTotal, Norton Safe Web, URLVoid, and ScanURL. At the time of writing this, none of the download sites showed any issues on the website checkers.

On the web since 2004 and Alexa-ranked at 625, FileHippo is solid. FileHippo states that they hand-pick the software, and test it for malware and viruses. They also don’t allow software that bundles other software into it or browser toolbars. FileHippo currently has over 40,000 program versions listed.

Be careful if you do a web search for FileHippo. There are a lot of sites out there with similar names and URLs. 

Nirsoft is a freeware utility site that was created and currently run by a guy named Nir Sofer. He’s single-handedly written all of the software utilities that you see on the site.

Each utility is completely free and usually very tiny in size. That’s because each utility is designed to perform one task and one task only. For example, some of the most popular utilities on the site are the password viewers, which will show you passwords stored on your computer, in your browser, etc.

Its sister site is Download Crew Store, where you can get deeply discounted proprietary software. Between the two you’ll get all you need as cheaply as possible.

So if an update to your favorite app makes an unwanted change, you could download the older version here and roll it back. File Horse also curates a directory of free cloud apps.

Don’t let the early-2000’s design fool you. Major Geeks is a legitimate free software download site. Founded in 2001, Major Geeks built a reputation by being one of the first to test all the software they offer. 

First, they check the reputation of the company and software, then they scan it with several virus scanners, including VirusTotal. If it makes it past that, Major Geeks actually installs the software on their own VMWare Workstation to test the functionality. If it meets their standards, then the software gets listed. This thoroughness warrants their military-style theme.

Partly a website and partly an app that’s probably already on your computer, Microsoft Store does have a lot of good freeware. Being Microsoft, there’s already a reputation in place and you’d like to think they’re hosting safe software.

Some of them are from the big names you already know, like Netflix, Apple, and, of course, Microsoft. Some are made by smaller development teams but can be very useful. Not all apps are free. There are thousands that are and it’s easy to find them. Just search on ‘free’.

Beyond that, you should also check out the great Sysinternals tools that used to be a separate site, but Microsoft purchased. The tools are still updated, but are geared more towards geeks.

Anymore Good Free Software Sites?

There are a few more good safe free software sites, but if you can’t find what you need on the sites above, then they’re not going to help much. Over time, you’ll get to know the sites you like that have the software you need. 

Remember to always check the downloaded file with your antivirus app or through Virus Total. If possible, test the program installation in a virtual machine or sandboxed environment. 

What Is A Cold Boot Attack: Explanation And Staying Safe

Cold Boot Attack is yet another method used to steal data. The only thing special is that they have direct access to your computer hardware or the whole computer. This article talks about what is Cold Boot Attack and how to stay safe from such techniques.

What is Cold Boot Attack

In a Cold Boot Attack or a Platform Reset Attack, an attacker who has physical access to your computer does a cold reboot to restart the machine in order to retrieve encryption keys from the Windows operating system

They taught us in schools that RAM (Random Access Memory) is volatile and cannot hold data if the computer is switched off. What they should have told us should have been …cannot hold data for long if the computer is switched off. That means, RAM still holds data from few seconds to few minutes before it fades out due to lack of electricity supply. For an ultra-small period, anyone with proper tools can read the RAM and copy its contents to a safe, permanent storage using a different lightweight operating system on a USB stick or SD Card. Such an attack is called cold boot attack.

Imagine a computer lying unattended at some organization for a few minutes. Any hacker just has to set his tools in place and turn off the computer. As the RAM cools down (data fades out slowly), the hacker plugs in a bootable USB stick and boots via that. He or she can copy the contents into something like the same USB stick.

Since the nature of the attack is turning off the computer and then using the power switch to restart it, it is called cold boot. You might have learned about cold boot and warm boot in your early computing years. Cold boot is where you start a computer using the power switch. A Warm Boot is where you use the option of restarting a computer using the restart option in the shutdown menu.

Freezing the RAM

This is yet another trick on the sleeves of hackers. They can simply spray some substance (example: Liquid Nitrogen) on to RAM modules so that they freeze immediately. The lower the temperature, the longer RAM can hold information. Using this trick, they (hackers) can successfully complete a Cold Boot Attack and copy maximum data. To quicken the process, they use autorun files on the lightweight Operating System on USB Sticks or SD Cards that are booted soon after shutting down the computer being hacked.

Steps in a Cold Boot Attack

Not necessarily everyone uses attack styles similar to the one given below. However, most of the common steps are listed below.

Change the BIOS information to allow boot from USB first

Insert a bootable USB into the computer in question

Turn off the computer forcibly so that the processor doesn’t get time to dismount any encryption keys or other important data; know that a proper shutdown may too help but may not be as successful as a forced shut down by pressing the power key or other methods.

As soon as possible, using the power switch to cold boot the computer being hacked

Since the BIOS settings were changed, the OS on a USB stick is loaded

Even as this OS is being loaded, they autorun processes to extract data stored in RAM.

Turn off the computer again after checking the destination storage (where the stolen data is stored), remove the USB OS Stick, and walk away

What information is at risk in Cold Boot Attacks

Most common information/data at risk are disk encryption keys and passwords. Usually, the aim of a cold boot attack is to retrieve disk encryption keys illegally, without authorization.

The last things to happen when in a proper shutdown are dismounting the disks and using the encryption keys to encrypt them so it is possible that if a computer is turned off abruptly, the data might still be available for them.

Securing yourself from Cold Boot Attack

On a personal level, you can only make sure that you stay near your computer until at least 5 minutes after it is shut down. Plus one precaution is to shut down properly using the shutdown menu, instead of pulling the electric cord or using the power button to turn off the computer.

You can’t do much because it is not a software issue largely. It is related more to the hardware. So the equipment manufacturers should take the initiative to remove all data from RAM as soon as possible after a computer is turned off to avoid and protect you from cold boot attack.

Some computers now overwrite RAM before completely shut down. Still, the possibility of a forced shutdown is always there.

The technique used by BitLocker is to use a PIN to access RAM. Even if the computer has been hibernated (a state of turning off the computer), when the user wakes it up and tries to access anything, first he or she has to enter a PIN to access RAM. This method is also not fool-proof as hackers can get the PIN using one of the methods of Phishing or Social Engineering.


The above explains what a cold boot attack is and how it works. There are some restrictions due to which 100% security cannot be offered against a cold boot attack. But as far as I know, security companies are working to find a better fix than simply rewriting RAM or using a PIN to protect the contents of RAM.
