BlackDream Ransomware Produces Verbose Ransom Note

While examining new malware sample submissions, our research team came across the BlackDream ransomware, which falls into the category of programs that encrypt data with the intention of demanding payment for decryption. On our test system, BlackDream encrypted files and altered their file names.

The original file names were extended with a unique identifier, the email address of the cybercriminals, and a ".BlackDream" extension. To clarify, a file that was originally named "1.jpg" now appeared as "1.jpg.[9ECFA84E].[Blackdream01@zohomail.eu].BlackDream." After this process, a ransom note named "ReadME-Decrypt.txt" was deposited.

The ransom message assures the victim that the files are not damaged but rather encrypted and inaccessible. It also suggests that seeking help for data recovery from sources other than the attackers (e.g., third-party tools or services) may result in the data being rendered permanently undecryptable.

The note hints that the decryption process will involve making a ransom payment in Bitcoin cryptocurrency (with the specific amount left unspecified). Additionally, the victim is directed to send a couple of encrypted files meeting certain specifications to the cybercriminals for a free decryption test.

How Can Ransomware Infect Your System?

Ransomware can infect your system through various means, and cybercriminals are constantly evolving their tactics to target vulnerabilities. Here are common ways ransomware can infect your system:

• Phishing Emails: The most common method is through phishing emails. You may receive an email that appears legitimate but contains malicious attachments or links. Clicking on these links or opening infected attachments can trigger a ransomware download.
• Malicious Websites: Visiting compromised or malicious websites can lead to drive-by downloads. In this scenario, ransomware is silently downloaded and executed on your system without your knowledge or consent.
• Malvertising: Malicious advertising (malvertising) can lead to ransomware infections. Cybercriminals can inject malicious code into online ads, and when you click on these ads or visit a compromised website with such ads, ransomware can be delivered to your system.
• Fake Software or Updates: Ransomware can be bundled with fake software or updates. You might think you're downloading a legitimate program or an update, but it's actually delivering ransomware to your system.
• Exploiting Software Vulnerabilities: Cybercriminals can take advantage of vulnerabilities in your operating system or software applications. If your system isn't up-to-date with security patches, it becomes more susceptible to exploitation.
• Social Engineering: Cybercriminals might trick you into running malicious code on your system. They could impersonate a trustworthy entity or use social engineering techniques to convince you to execute a harmful file.
• Remote Desktop Protocol (RDP) Attacks: If you have RDP enabled on your system and it's not properly secured with strong passwords and network security measures, attackers can gain unauthorized access and deploy ransomware.
• Malicious Downloads: Downloading files, especially from untrusted sources, can lead to ransomware infections. Torrents, cracked software, and pirated content are often used as bait to spread ransomware.
