Best Ransomware Scanners

There are many types of ransomware attacks, and they can all ruin your business. Ransomware can be implemented in many ways but the two most frequently practiced strategies are the encryption of files and data theft

Hackers that use encryption-based ransomware render all files on a computer unusable by encrypting them. Usually, the only way to recover those files is to pay for the decryption key. Disclosure ransomware attacks steal data from your system, and the hacker threatens to publish that information if a ransom isn’t paid.  Suppose your company holds personally identifiable information (PII) on members of the public, and that data gets released. In that case, you can be fined and sued, and you will lose data security standards accreditation.

In some business sectors, compliance with data privacy standards is made a condition of contracts. For example, the payment card clearing sector requires conformance to PCI DSS. If you don’t have that accreditation, you can’t process payments by card – for most online businesses, that ban would put them out of business. So, there is a lot at stake.

Here is our list of the best ransomware scanners:

Protection against ransomware

You can’t afford to let hackers get at your essential data stores. Data thieves manually gain access to a system and explore it to find valuable data. Ransomware is an automated process and can be a bit hit and miss.

Some ransomware will only infect the computer to which it first gets access, while others can move around the network, infecting all of the endpoints before triggering the attack. You improve your chances of recovering from an encryption ransomware attack by backing up all files and then just restoring them, wiping out the encryption without paying the ransom. However, some ransomware systems can infect backup stores as well.

Disclosure ransomware is very difficult to recover from without paying the ransom. Therefore, preventing this type of attack is your only hope. So, defending stores of PII is very important.  The most important way to protect against all types of ransomware is to install security software that will spot it as soon as it gets onto an endpoint and prevent it from triggering.

Ransomware scanners

Ransomware is an automated attack. It is malware, so your best form of defense against these attacks is through advanced malware detection systems. Spotting ransomware requires a combination of security services. It needs significantly evolved systems that spot anomalies rather than the old-fashioned type of anti-virus packages that just look for a list of filenames or processes. Ransomware is evolving all the time, and you don’t want to be caught out as the first victim of a new variant that AV companies haven’t spotted yet.

There are two types of systems that provide appropriate defense against ransomware: next-generation AVs and next-generation SIEMs. In addition, some security system providers have developed services that form a platform of protection services. These systems establish a baseline of regular activities performed by each user and device. This is called user and entity behavior analytics (UEBA). A typical net-gen system then flags any activity that doesn’t fit that pattern of normal behavior.

The next-gen strategy defends against previously unencountered malware. This is important in ransomware because that type of system only operates for a short period. After a brief attack campaign, the hacker owners revamp their ransomware so that it won’t be spotted by those security systems that have recorded its operating procedures and updated all instances with this information.

Hackers are constantly changing their ransomware into new versions or even entirely new systems. They can use several different entry methods, but the most common are:

  • An RDP attack through an unprotected port
  • An installer disguised as an email attachment

The use of the Remote Desktop Protocol is an intruder-like strategy, and a download from an email attachment is a typical method used by Remote Access Trojans (RATs). In addition, some ransomware combines these two operating methods, using a download for the initial infection and then RDP to replicate the malware around the network, continuing to seize all devices and backup stores.

A competent ransomware scanner will catch both of these two infection methods.

The Best Ransomware Scanners

The most appropriate ransomware protection system for you depends to a great extent on your operating configuration. For example, you need to be sure that the ransomware scanner can interact with the operating systems that you are running on your sites. In addition, if you use cloud storage, you need to ensure that your scanner can identify ransomware before it gets uploaded. Beyond these operating system considerations, there are several important factors to determine.

Our methodology for selecting a ransomware scanner  

We reviewed the ransomware prevention system market and analyzed tools based on the following criteria:

  • The ability to spot zero-day attacks
  • The inclusion of behavior baselining and anomaly detection
  • Alerts for detected attacks
  • The ability to implement automated threat prevention actions
  • System hardening features
  • A free trial or a demo system for a cost-free assessment
  • Good value for money

Depending on whether you hold a lot of PII on your system, you might need to consider buying in several tools to protect your company from ransomware attacks wholly. Using the above selection criteria, we drew up a shortlist of some excellent security packages that will keep you safe from ransomware.
