What is Cryptoware Viruses such as the Locky Virus

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

Meeting IT security compliance standards is crucial for businesses that handle sensitive data, particularly in industries such as healthcare, finance, defense, and e-commerce. Regulatory frameworks such as HIPAA, CMMC, PCI-DSS, and GDPR exist to help ensure businesses protect customer information and maintain robust cybersecurity practices. Unfortunately, many organizations fall short of these requirements, often due to common, avoidable mistakes. These gaps can result in costly fines, data breaches, and reputational damage, which can significantly impact the business's bottom line and customer trust. 1. Failing to Conduct Regular Risk Assessments The Pitfall: Many businesses overlook the importance of conducting routine risk assessments. Without these, it’s challenging to identify vulnerabilities or evaluate whether your current cybersecurity controls meet compliance standards. How to Avoid It: Implement a regular risk assessment schedule. Work with a qualified IT provider to evaluate your systems, identify weaknesses, and document remediation plans. These assessments should be performed at least annually, or whenever significant changes to the system occur. 2. Inadequate Employee Training The Pitfall: Your employees are your first line of defense—and often your most significant vulnerability. A common compliance issue arises when businesses fail to train staff on cybersecurity best practices or on handling sensitive data appropriately. How to Avoid It: Invest in ongoing cybersecurity awareness training. Ensure employees understand how to recognize phishing emails, create strong passwords, and report any suspicious activity. Training should be updated regularly to reflect current threats and compliance requirements. 3. Improper Data Handling and Storage The Pitfall: Storing sensitive data in unsecured locations, failing to encrypt information, or retaining data longer than necessary are significant compliance risks. These practices are often flagged during audits. How to Avoid It: Adopt data classification policies that define how different types of data should be handled; encrypt sensitive data both at rest and in transit. Establish clear data retention policies and ensure that obsolete data is disposed of securely. 4. Lack of Incident Response Planning The Pitfall: When a security incident occurs, time is of the essence. Many businesses lack a documented incident response plan, or their existing plan hasn’t been thoroughly tested. This can lead to delayed responses, increased damage, and regulatory penalties. How to Avoid It: Develop a formal incident response plan that includes roles, responsibilities, communication protocols, and steps for containment and recovery. Run simulated breach scenarios with your IT team to ensure everyone knows how to respond effectively. 5. Using Outdated Software or Systems The Pitfall: Running outdated operating systems, software, or firmware is a common issue that can lead to compliance failures. Unsupported technologies are more vulnerable to exploitation. How to Avoid It: Keep all systems and applications up to date with the latest patches. Use automated tools to track software versions and receive alerts about end-of-life technologies. Schedule regular maintenance windows to apply updates and upgrades. 6. Insufficient Access Controls The Pitfall: Allowing too many employees access to sensitive data—or failing to revoke access when it’s no longer needed—can lead to data breaches and non-compliance. How to Avoid It: Implement role-based access controls and follow the principle of least privilege. This principle means that each user should have the minimum level of access necessary to perform their job. Regularly audit user accounts and permissions to ensure access is current and appropriate. Use multi-factor authentication (MFA) to add an additional layer of protection. 7. Neglecting Third-Party Vendor Risks The Pitfall: Businesses often overlook the fact that their compliance responsibilities extend to third-party vendors. If a vendor mishandles your data, you could still be held accountable. How to Avoid It: Vet third-party vendors carefully. Ensure they meet the same compliance standards as your business and include security requirements in your contracts. Conduct periodic audits or request compliance certifications from your vendors. 8. Failing to Document Policies and Procedures The Pitfall: Even if your security practices are strong, failing to document your compliance policies can result in audit failures. Regulators want to see evidence that you have formal processes in place. How to Avoid It: Create and maintain clear documentation for all compliance-related policies, including data protection, access control, incident response, and employee training. Make these documents easily accessible for audits and regularly review them to ensure updates are current. Conclusion Compliance with IT security standards is not a one-time project—it requires ongoing attention, regular updates, and a proactive approach to maintain effectiveness. By understanding and addressing these common pitfalls, your business can stay ahead of regulatory requirements, strengthen its security posture, and reduce the risk of costly incidents. This ongoing attention is crucial to maintaining your business's security and audit readiness.
