LazagneCrypt Ransomware – Ways of Distribution

The analyses of LazagneCrypt ransomware samples reveal that an executable file called brc.exe triggers the infection. That malicious file may be distributed via different methods. Among the most preferred are email spam attachments, compromised links and software bundles.

There are several known traits of the emails that are trying to deliver a ransomware infection. First, they need to look legitimate so they often use the names of popular services, websites, stores and governmental institutions. The senders pretend to be representatives of these companies and the message is trying to provoke your emotional triggers. Such emails aim to convince you that the information of an attached file is extremely important and you should view it as soon as possible. However, once you open the file on your PC, it causes an infection with LazagneCrypt ransomware.

In an attempt to deliver the ransomware payload hackers may create colognes of particular web pages and inject the malicious script into their source code. What lefts is the spread of the corrupted links across the net. This may happen via emails, instant messages, social media channels and malvertising campaigns.

What is typical for the software bundles is that the installers of supposedly useful apps contain additional components that may remain hidden in the Advanced or Custom options. As these parts are usually set for installation by default you may unknowingly infect your system with LazagneCrypt ransomware.

commonly used file names and folders

Among the observed impacts are believed to be modifications of some important registry keys. Commonly ransomware infections like LazagneCrypt target the Run and RunOnce registry keys as they contain information which programs should run each time a user logs on the system. By adding specific entries under these keys the ransomware can start each time you turn log on your system profile. The exact location of these keys is:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

The analysis conducted by the security researcher Karsten Han has discovered a devastating fact about LazagneCrypt ransomware. As explained the threat can steal passwords from the compromised machine and then send them to hackers.

For the purpose, LazagneCrypt employs the LaZagne password recovery tool. The tool can retrieve passwords stored by commonly-used software apps that are installed on the compromised computer. The password dumps are then uploaded to hackers’ controlled account via the service SwissDisk.

A specific trait of LazagneCrypt crypto virus is a file that contains a ransom message. The file is likely to be dropped on the Desktop.

→.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .hwp, .pdf, .php, .asp, .aspx, .html, .xml, and .psd
