Cdtt Ransomware Scrambles Victims' Files

Following a recent examination of newly discovered malware samples, it has been established that Cdtt is part of the Djvu ransomware family. Its primary goal is to encrypt data, appending the ".cdtt" extension to filenames (e.g., renaming "1.jpg" to "1.jpg.cdtt," "2.png" to "2.png.cdtt," etc.) and generating a ransom note named "_readme.txt."

It's crucial to note that Djvu variants are often distributed alongside information stealers. The ransom note assures victims that they can recover all their files, including pictures, databases, and crucial documents, emphasizing the use of strong encryption and a unique key. According to the note, the sole method for file restoration is through the acquisition of a decrypt tool and a personalized key.

The ransom note offers a free decryption of one file as a guarantee, with the condition that the file does not contain valuable information. The specified cost for the private key and decryption software is $1999, with a 50% discount available if contacted within the initial 72 hours, reducing the price to $999.

The note warns that data restoration is unattainable without payment. To obtain the necessary software, victims are instructed to reach out to the email address support@freshingmail.top or an alternative address, datarestorehelpyou@airmail.cc.

How Can Ransomware Infiltrate Your System?

Ransomware can infiltrate computer systems through various methods, taking advantage of vulnerabilities and unsuspecting users. Here are some common ways ransomware can enter a system:

Phishing Emails: One of the most prevalent methods is through phishing emails. Cybercriminals send seemingly legitimate emails that contain malicious links or attachments. Clicking on these links or opening infected attachments can lead to the installation of ransomware.

Malicious Websites: Visiting compromised or malicious websites can expose your system to ransomware. Drive-by downloads, where malware is automatically downloaded and installed without user interaction, are a risk associated with visiting such websites.

Malvertising: Malicious advertisements on legitimate websites can redirect users to websites hosting ransomware. Clicking on these ads may trigger the download and execution of the ransomware.

Exploiting Software Vulnerabilities: Ransomware creators often target vulnerabilities in software to gain unauthorized access. It is crucial to keep operating systems and applications up-to-date with the latest security patches to minimize the risk of exploitation.

Drive-by Downloads: Ransomware can be delivered through drive-by downloads, where malware is automatically downloaded when a user visits a compromised or malicious website. These downloads may exploit browser vulnerabilities or use deceptive tactics to trick users into installing the malware.

Social Engineering: Cybercriminals may use social engineering techniques to trick users into voluntarily downloading and executing malicious files. This could involve disguising malware as legitimate software updates, cracking tools, or other seemingly harmless files.
