How You Got Hit with Ransomware and What to Do to Prevent It from Happening Again

Imagine walking into your office on a Monday morning, ready to start the workweek. You sit down at your desk, turn on your computer, and instead of your usual login screen, you're greeted with a message: your files have been encrypted, and the only way to get them back is to pay a ransom. You've been hit with ransomware. But how did this happen? How did the attackers get into your system? There are several vectors for a ransomware attack, including phishing emails, malicious websites, exploit kits, and more. Let's take a closer look at each of these attack vectors and how they work.

The Most Likely Vectors for a Ransomware Attack

• Phishing Emails: This is one of the most common methods. Attackers send emails that appear legitimate, often with malicious attachments or links. When users open the attachment or click the link, the ransomware is downloaded and executed.
• Malicious Websites and Drive-by Downloads: Visiting compromised or malicious websites can result in a drive-by download, where ransomware is automatically downloaded and installed on the user’s system without their knowledge.
• Exploit Kits: These are automated tools that cybercriminals use to exploit vulnerabilities in software applications, operating systems, or browsers. When a user visits a compromised website, the exploit kit scans for vulnerabilities and, if found, delivers the ransomware.
• Remote Desktop Protocol (RDP) Vulnerabilities: Cybercriminals often exploit weak or improperly secured RDP connections to gain access to a system. Once they have access, they can deploy ransomware.
• Software Vulnerabilities and Unpatched Systems: Outdated software with known vulnerabilities can be exploited by ransomware. Attackers scan for such vulnerabilities and exploit them to gain access and deploy ransomware.
• Infected Software Downloads: Downloading software or applications from untrusted or third-party sources can result in installing ransomware. These downloads might be bundled with malicious software.
• Removable Media (USB Drives): Inserting infected USB drives into a computer can trigger the installation of ransomware. This method relies on physical access or the sharing of USB drives between users.

The most common vector of attack comes by way of a phishing email. Attackers will send legitimate looking emails to your users, instructing them to open an attachment or sign into a website. Malicious payloads are downloaded, or passwords are then compromised. Another common attack vector is an open RDP port. RDP (Remote Desktop Protocol) vulnerabilities are one of the most common vectors for ransomware attacks, along with phishing emails. RDP is a protocol that allows users to remotely access their computers. To do this, users often open a port on their router, which can make it easier for cybercriminals to gain access to their system. Additionally, if the default administrator account is enabled, it can make it even easier for attackers to hack into the system. To mitigate these risks, it is important to secure remote access to your network by using strong passwords, whitelists, enabling two-factor authentication, and limiting the number of users who can access the system remotely.

Preventing Ransomware Attacks

Implementing strong cybersecurity practices can help mitigate the risks of ransomware attacks:

• Regular Software Updates: Ensure that all software, including operating systems and applications, are kept up-to-date with the latest security patches.
• Employee Training: Educate employees on recognizing phishing attempts and the importance of not clicking on suspicious links or attachments.
• Robust Antivirus Software: Use comprehensive antivirus solutions that monitor for and halt ransomware from spreading across your network.
• Securing RDP Access: Implement strong passwords, whitelists, two-factor authentication, and limit the number of users who can access the system remotely.
• Regular Backups: Secure backups both onsite and offsite and test them regularly to ensure functionality. You'll never have to pay a ransom if your systems are secured and backed up effectively.

Our Recommendations

We recommend a highly effective endpoint detection and response system such as Sentinel One, regular security audits, and a robust, always-secured backup of your critical data systems both onsite and offsite.
