What is Cryptoware Viruses such as the Locky Virus

Scott Starost • Apr 24, 2018

What is Cryptoware? 

Becoming infected with malware can be problematic for any business, but it is even more troubling whenever that malware is cryptoware. Encountering a cryptoware virus such as Locky can quickly bring your operations to a halt, which is why it is important to know how to protect yourself against these type of cyber attacks. The Locky virus, for example, can be disguised as an email delivering a document with an invoice requesting payment methods for your data. If the user opens this document and follows it’s directions this could lead a company down a very damaging path.

Cryptoware is a type of malware that belongs to the ransomware families. It begins as a Trojan virus that is normally hidden in email attachments. When the receiver opens the attachment, the virus then begins encrypting ransomware files on that computer. Once these files are encrypted, the user will then have to pay a “ransom” to have the files unencrypted. Most people are willing to pay up since the level of encrypted data is so secure that it would take a great deal of time and resources to break it. However, even if you make a ransom payment, there is no guarantee you will actually get your sensitive information back.

How Files are Infected

A cryptoware attack begins with an email attachment from what appears to be a reputable email address. Although the attachment is an executable file, the .exe extension is not immediately visible since most email clients hide file extensions by default. Instead, the attachment is marked as “letter.pdf” and therefore does not appear unusual. However, when the attachment is opened, the Trojan virus silently executes, encrypting files until all of them are useless. When finished, the virus will send you a ransom notice via a popup on your screen. This notice requires payment through Bitcoin, making it very difficult to track who you are sending the money to.

Best Practices For Avoiding a Cryptoware Infection

There is no method of ridding your computer of cryptoware aside from paying the ransom, which means that cyber security prevention is key. Here are some recommendations for Best Practices to follow to protect your company from a cryptoware attack.

  1. Experts recommend keeping your anti virus program up to date on your computer systems. Also, keep other software up to date as well such as your Adobe Flash Player and Java.
  2. Security experts also recommend only opening email attachments from those who you trust. And be extra cautious with email attachments that are sent from some who you do not know.
  3. Turn your user account control settings to Always Notify so that programs cannot make changes to your computer without telling you first.
  4. Enable your computer to reveal file extensions. This is a good way to see a file in its entirety. Sometimes “.EXEs” (executable files) are used by ransomware developers to deliver corrupted files. You’ll want to be able to see the whole file name to make sure there are no file extensions such as “.exe” tucked into a file name. An example would be: rainshowers.jpg.exe
  5. Back up information using a cloud storage service such as OneDrive or Google Drive so that if you are infected, you won’t feel pressured to pay the ransom. Using a pen drive or portable operating system to access emails can be useful as well. Also, it’s helpful to have a backup strategy in place as to determine where copies of backup files will be specifically stored. This will help to keep files secure in case of a cyber attack and help you remain calm knowing exactly where all copies of your backup files are located.

Booming Business

One reason why cryptoware is such a growing threat is that it is a booming business. Cerber is one company that offers Ransomware as a Service (RaaS), offering an affiliate program that now has 160 participants. Affiliates are able to launch their own campaigns via the Cerber platform, and are able to keep 60% of the profits. In exchange, the company provides them with access to management tools, Bitcoin laundering, and the harmful code. Despite the fact that only 0.3% of all victims pay, Cerber is still on track to make around $2.3 million by the end of 2016.

Types of Ransomware Strains

  • CryptoLocker
  • CryptoWall
  • CTB Locker
  • Locky
  • Petya Trojan

Since ransomware is such a lucrative business, there are likely to be even more attacks in the future. You must constantly be aware of the dangers if you are to avoid the costly effects of becoming a victim.

In today's digital landscape, cybersecurity is paramount to protect sensitive business information from falling into the wrong hands. As a business owner, you understand the value of securing your data and safeguarding your reputation. That's where dark web monitoring comes into play. What is Dark Web Monitoring? The dark web is a hidden part of the internet where illegal activities often take place, including the buying and selling of stolen data. Dark web monitoring involves scanning the dark web to identify any instances of your business's compromised information being traded or sold. By monitoring these underground networks, you gain valuable insights and can take immediate action to mitigate potential risks. Key Features and Benefits Real-time Alerts: Dark web monitoring provides real-time alerts, notifying you the moment your business's data appears on the dark web. This allows you to respond swiftly and take the necessary steps to protect your sensitive information. Comprehensive Coverage: Dark web monitoring casts a wide net across various dark web platforms, ensuring comprehensive coverage. It searches for mentions of your business, compromised credentials, financial information, and other sensitive data that may have been exposed. Access to an Expert Support Team: With dark web monitoring, you're not alone in the fight against cyber threats. You have access to an expert support team that can guide you through the process, answer your questions, and provide recommendations to strengthen your cybersecurity posture. Addressing Misconceptions Misconception 1: Dark web monitoring is only necessary for large businesses. Cybercriminals do not discriminate based on business size. Any organization, regardless of its scale, can become a target. Small businesses are particularly vulnerable as they often lack the robust security infrastructure that larger enterprises may have. Dark web monitoring is essential for all businesses, regardless of their size, to proactively protect their data. Misconception 2: Dark web monitoring is too technical to understand. While dark web monitoring may involve technical processes, the service providers are equipped to simplify the complexities for you.

You don't need to be a cybersecurity expert to benefit from dark web monitoring. Misconception 3: Dark web monitoring is expensive.

Additionally, many service providers offer flexible pricing options to suit different business needs, making it an affordable solution for businesses of all sizes.
