How Small Businesses Can Prevent Ransomware Encryption

With the widespread Ransom.WanaCrypt0r. (WanaCry) attacks in the news, the world has become painfully aware of the havoc encrypted ransomware can cause. It has infected the PC’s, Macs, mobile devices, networks and servers of both individuals and businesses of all sizes. There are many versions of ransomware, including Jaff, Locky, Sage, Cerber, Spora, Cryptoblock, SamSam, Findzip, Goldeneye, KeRanger and more.

The US is the top target by far but the infection rate is growing in other countries, including Canada.  The following chart illustrates detections by Symantec (Norton), which is not to be confused with the much higher number of attacks they actually blocked.

Once infected, your spreadsheets, documents, photos, videos and other files will no longer be accessible to you. The ransom demanded to release your encrypted data can range from a few hundred dollars to hundreds of thousands. The mean average ransom demanded by attackers increased from $294 to $1,077 in 2016, according to the 2017 Symantec Internet Security Threat Report.

You will see a screen similar to this one if you’ve been infected:

There are several ways hackers can infect computers or operating systems, but it usually starts with a single email. The recipient clicks on a link or opens an attachment, the attack begins and your business comes to a grinding halt. You can also be infected via downloads (including apps) or file sharing, or by clicking links in pop-up windows when browsing the Internet.

Prevention is Your Best Defense Against Ransomware

Once you’ve been infected by ransomware, there is little you can do but pay the ransom or start again with a clean operating system and secured backup files. Prevention is the most effective way to protect your business and customer data.

Some malware prevention software is better than others. We found out the hard way that those who specialize in malware will find and prevent it better than your average anti-virus software.

The first time we ran MalwareBytes, it found (and fixed) a long list of malware that our anti-virus software missed. One of the reasons we tried it was to be rid of stubborn malware that added advertisements and messed with search results. We ran our anti-virus software and it would seem like it was gone, only to come back when we restarted our laptop. After downloading the MalwareBytes free trial and running it once, the malware was gone. We subscribed to their premium anti-malware software and have used it in combination with standard anti-virus software ever since.

After several years of excellent performance, we weren’t surprised when MalwareBytes announced they were specializing in ransomware prevention as well.

MalwareBytes stops unknown and known ransomware with proprietary technology that works proactively to shield your files. This is a powerful, complete defense that blocks ransomware, and not a simple decryption tool. That means you’re protected from new threats even before they’ve been identified, including the most recent and widespread ransomware, Ransom.WanaCrypt0r (WannaCry).

Malwarebytes signature-less anti-exploit technology blocks the infection vector, while our anti-malware technology blocks the payload pre-execution,” their website explains. “Our anti-ransomware technology prevents users’ files from being encrypted and will stop any future unknown ransomware variants. It combines multiple security layers with the best-informed telemetry to block an attacker at every stage of the kill chain.”

Other ways to prevent infection include:

If you are attacked by ransomware, report it to law enforcement such as Canadian Anti-Fraud Centre in Canada or your local FBI field office in the United States.
