Prevention is Best!

Prevention is the best Safeguard

Prevention is the best way to ensure you are never infected with spyware and your data is never lost or stolen. It is possible to clean up an infected machine and remove spyware but sometimes the damage from certain spyware, such as ransomware, cannot be fixed as files become encrypted or otherwise corrupted.

While no single solution available is a silver bullet, the following list outlines some of the best practices in lessening the risks of losing data after an infection:

1) Backup your files and software! Having backup copies of your photos, documents, software, and other files can make sure you never lose them to a malware infection such as ransomware encryption. Many people choose to use external drives or the cloud for their backups, but keep in mind that if you use external drives, the data can still be at risk if you leave your backup drives connected to your machine at all times.

We at SUPERAntiSpyware offer an Online Backup Solution as an optional service when purchasing SUPERAntiSpyware at $6.95 a month. This subscription allows you to back up and protect your important files and documents onto a cloud-like server so you always have copies of your important files.  You can read more about our backup services here: https://www.backup.support.com

2) Keep SUPERAntiSpyware up to date and run regular scans. We update our definition list twice a day to make sure our users catch the latest threats, as well as periodically release software updates. It is imperative users keep up to date so their software continues finding the latest threats. In order to make sure that nothing creeps in between scans, we recommend regular scanning at least once a week, if not every day.

3) Update your Windows Operating System and Software you use. Make sure you always are using the latest version of Windows with the latest updates and security fixes. Most Windows updates are patches for existing and/or potential vulnerabilities, so keeping these holes filled is crucial in stopping the spread of malware. Additionally, using unsupported operating systems (anything older than Windows 7 as of right now) can leave you just as unprotected. If you are using web browsers such as Firefox, Chrome, or others, always make sure you are using the latest versions, and don’t forget to update any add-ons, plugins, or extensions you use to the latest editions.

4) Double Check Emails before opening them. Check the sender of every email you receive. If you do not know them, or the email looks suspicious, do not open it! Delete it! Do the suspicious emails include links to click or strange attachments? Do not click the links or open the attachments no matter how innocent they sound. If it claims to be from an official organization, call them and ask if the email is legit. Better safe than sorry!

5) Use strong passwords and/or multi-factor authentication. Good passwords are long. Good passwords also contain capital and lower case letters, numbers, and special characters. Do not use an easily accessable password that contains personal information like your birthday or the name of your pet, and do not use the same password for every website! This makes it harder for hackers to gain access to your personal information, especially when you use different passwords for every site. It might be a bit more to remember, but it diminishes the risk and the headache of sorting everything out after your information is stolen.

Many sites, such as banks, often will have multi-factor authentication available. With these systems, you not only need a password, but you also will need a special code that is often randomized on a dongle or smart phone app. These types of systems are more secure than just a typical password, as the extra step is incredibly difficult to hack into.

6) Use an Ad blocking Extension. Software such as Adblock Plus and uBlock Origin for your internet browsers are free, cross-platform browser extensions that filter unwanted content such as ads, pop-ups, rogue scripts, and even IP leaks. Using an ad blocking extension on your web browser will greatly lessen the impact of “Malvertising”, website ads that drop rogue programs onto your PC without your knowledge. While these programs might not block every ad you encounter, the chances of you running into something particularly malicious will be reduced dramatically.

7) Remove unsupported software. Many software programs, such as Flash or QuickTime, are no longer supported by their publishers, or are no longer supported by modern web browsers. This means that existing versions can have massive security flaws, despite their being many users who still have the software installed on their computers. It is recommended that users uninstall software that has been abandoned by their creators, especially if it is something that deals with content on the web.

At the same time, many newer pieces of software cannot run on older operating systems such as Windows 98, Windows ME, and even Windows XP. Keep your operating system up to date! When Microsoft stops supporting an old operating system, they stop all updates, which can lead to vulnerabilities being exploited.

8) Don’t talk to tech support scammers. If you’re on the internet and suddenly get a pop-up or email claiming your PC is infected with a virus, and that you need to call a listed number immediately, do not do it! A real security company wouldn’t sell their services from sketchy pop-ups or emails. These companies typically list a 1-800 number for you to call so they can try to lure you into spending potentially hundreds of dollars and giving them remote access to your PC.  More likely than not, they will try to infect you or steal personal information during their remote access “work”.

9) Make sure you are on secure connection when purchasing products online or entering in personal information. You can tell you are on a secure website when the URL reads “https” and not just “http.” This is also referred to as HTTP over SSL which is encrypted. This protects against eavesdropping and tampering. Often, the address bar will change color or display a lock icon next to the URL you are visiting if you are connected through a secure HTTPS connection.

10) Use a firewall. Since Windows XP, every Microsoft operating system has come with a firewall. It is recommended you make sure this is always enabled. If you use a third-party firewall, it is also recommended you always keep it up and running. Firewalls use rules and examine network traffic as it passes in and out of your PC. If a connection does not follow the firewalls rules, it will be blocked. This also allows you to monitor activity on your network from intrusion attempts or if rogue software on your PC is trying to reach out to a hacker.

Remember to Stay Safe

Even the most cautious of people can get infected; however, by following these tips your risk of getting infected or being unable to recover from an infection will go down dramatically. Remember to stay safe, exercise caution, scan regularly, keep everything up to date, and backup your data often.

Ransomware: Revisited

Ransomware Revisited By SUPERAntiSpyware

A lot has changed in the world of ransomware since we last talked about it on this blog back in 2013. For those who are new to ransomware, this post should provide a primer of what this family of malware is and what it does. For those who are more well-versed, some of our best practices at the end of this post should help provide some extra prevention methods.

TeslaCrypt, Locky, CryptoLocker, CryptoWall, and other ransomware families are making their way around the internet at break-neck pace. If you find yourself in the unfortunate place of having fallen victim to this type of malware, you’ve essentially got two options: pay up or start from scratch. While this is not something that most people want to hear, it’s the unfortunate reality for a machine that’s been ravaged by these types of infections. Even the FBI has come out and stated that your best option at data retrieval is to pay the ransom (if you do not have proper backups)!

What is Ransomware?

Ransomware is a designation given to families of malware that encrypt your personal files, and then demand a ransom payment in order to be given the decryption key. The types of files that ransomware targets range from generic text files and documents, to pictures, to video games, to music, and even beyond. Unfortunately, the type of encryption that’s used is so strong, that newer versions of some ransomware are completely impenetrable.

Most ransomware families are spread by a special type of Trojan called a “dropper”. The purpose of a dropper is to run processes in the background of your machine to download and execute code from a remote server. That code then searches your computer for files of a specific type (or types), then modifies those files by scrambling them with high-end, two part encryption. After a critical mass of files have been encrypted, the ransomware will then typically create a few different unencrypted documents and/or display a dialogue on your machine telling you that you’ve been locked out of your files unless you pay the price. To add fuel to the fire, many different variants will have a timer imposed upon you for when payment is “due” to them. If you don’t pay in time, they either increase the ransom, or delete the encryption key from their server, thereby making it impossible to retrieve your files.

To make matters worse, many different ransomware variants will disable the Volume Shadow Copy Service on your machine. This service is used by Windows to perform automatic backups and create restore points. These backups are what you would typically use to “roll back” your computer to before a major change happened.

How did I get infected?

Ransomware droppers come in all different shapes and sizes, but one thing that’s true about them is once they’ve been started, it’s almost always too late. These droppers typically are files that you download from your email, other websites, or p2p servers (such as torrent sites). Unfortunately, this is changing rapidly, and we’re starting to see “drive-by” exploits occur in the wild through infected ad-streams on popular sites many people visit on a daily basis.

One of the most frustrating parts of ransomware infections are that they’re extremely difficult to clean up. Even if you run antivirus and antimalware scanners, once the damage has been done, there’s nothing that these pieces of software can do to reverse the damage. These tools, including SUPERAntiSpyware®, can remove the underlying cause of the infection (the dropper) in many instances, but the encryption itself can’t be reversed.

Some versions of ransomware will display messages saying that they are from the FBI, NSA, INTERPOL, or other law enforcement agency. They’ll accuse you of possessing illegal documents and/or visiting illegal websites. This type of scare tactic has fallen out of favor, as people have gotten wise to it. Most modern ransomware will simply display a page admitting freely that you’ve been infected and display instructions on how to pay the ransom.

If you have a home or office network, it’s also possible that your machine got infected due to sharing a network with another infected machine. Because of how these infections work, they simply spread out across the drive space they can see, encrypting whatever data that can be found, regardless if it is on the machine that was initially infected.

What about my data?

If your machine has fallen prey to a ransomware attack, there’s not a whole lot that can be done with the files that were encrypted. Creating new files without removing the underlying infection is a fool’s errand, as they will quickly become encrypted as well.

After coming to terms with the fact that your data has been encrypted, you will find yourself in the middle of an ethical quagmire. If you pay the ransom that is demanded, you will most likely get your files back; however, you’re actively giving these attackers what they want, which is your money. There’s also no guarantee that by paying, your files will be restored; however, if people didn’t get their files back by paying the ransom, why would people continue to pay? If you don’t pay the ransom, you will lose access to all of your files, some of which may be irreplaceable. This is probably one of the most difficult decisions you will make after an infection.

While we can’t tell you one way or the other to pay the ransom or not, one thing that makes it extremely easy to rebound from is the availability of recent backups. If your backups are good, it is far more palatable to format your machine and reinstall the operating system than it is to pay the ransom. There are a few older variants of ransomware that can be decrypted by special software; however, these versions aren’t found in the wild much anymore for that very reason.

How can I protect myself?

There are many different steps you can take in order to help ensure that your machine doesn’t fall victim to a ransomware attack. Below you will find some of the best practices we have to offer:

Back up your data frequently on an external hard drive AND in the cloud. One set of backups is very rarely going to provide you with 100% coverage, either due to timing differences between when you back up your data and what you’re working on, drive failures, or infection of files in your backup.

If you network computers in your home or office make sure that each machine has its own set of backups. Most ransomware infections can not only infect drives that are connected directly to the infected machine, but also the drives of machines that are connected to the same network as the infected machine.

Always disconnect physical backup drives from your machine when not in use. If you constantly have your backup drive plugged in, there’s a strong chance that the ransomware can find and encrypt files on your backup drive.

Don’t ever download from a site that tells you that something is outdated on your machine. Websites aren’t able to detect outdated software or drivers unless you give them access to your machine. If you think that you have outdated software, download the latest version directly from the publisher’s website.

Practice caution when downloading files of any kind, even if it’s something that your grandmother sent you. Many variants of ransomware will send out emails to logged-in accounts with copies of itself attached. Always make sure to save files to your machine before running them, and always scan those files with your antivirus and antimalware scanners.

Keep your antivirus and antimalware scanners up to date with both the most recent versions of the programs themselves and the most recent versions of the detection databases. You should also take this practice a step further and make sure to keep your operating system up to date as well, as many attacks rely on exploiting bugs that have already been patched.

Leave macros in Microsoft Office disabled if you do not use them regularly, and do not turn them on if you don’t. One of the most common attack vectors of ransomware is to have unknowing victims turn on macros in order to “fix” a document that appears to be corrupted. In actuality, once the macros are enabled, the dropper begins its work.

Don’t give yourself (or other users) more login power than you need. Having administrator rights to your machine is definitely something most people overlook. Unfortunately, if a ransomware infection sees that you have administrative access, it makes the computer much easier to infect.

(OPTIONAL) Use adblocking software while browsing the web, disable scripting within your web browser, disable Flash, and disable Java. Many of the drive-by attacks are distributed through infected advertisements, Javascript commands, or through the downloading of files automatically when you open the page. By turning off this vector of attack, you might limit some of your web browsing capability, but will be that much more secure against attacks.
