On August 7, 2020, we observed that the original ZIP archives on the server were replaced with password-protected archives. The complete list of URLs used in this campaign, along with the filenames, is provided in the indicators of compromise (IoC) section later in the blog.ĭuring the course of monitoring this threat actor, we noticed that the download links on the web page were updated frequently.

The download links on the web page lead to a ZIP archive containing the infostealer. The web user interface of the site uses the well-known LinkedIn logo and poses as a recruitment company called “Jobsfinder 3ee,” which pretends to help the candidates find relevant jobs in various geographical regions around the world. URL: hxxps:///įigure 1: The main web page uses the LinkedIn logo but actually hosts the malicious content. In this blog, we provide a detailed description of the tools, techniques, and procedures of this threat actor and the malicious binaries hosted on this site, as well as the credential phishing methods used.įigure 1 below shows the site that was set up by attackers on a legitimate website hosting server provided by Yola. Its major functionality is information stealing and exfiltrating data through SMTP.
NET-based binaries hosted on this site are related to the Agent Tesla malware and another previously unseen in-the-wild malware family. The bad actors also used a legitimate site hosting company, called Yola, to host the malicious content in an attempt to further look legitimate.

In August 2020, we observed network activity to a malicious site that used LinkedIn, a popular professional networking and job search site, as the lure for a social engineering scheme designed to steal a user’s credentials and spread malicious binaries. Sadly, this isn’t just a hypothetical scenario, as the Zscaler ThreatLabZ team observed a scheme just like this come across the Zscaler cloud. But that excitement can quickly turn to anger and despair when the job search tool you were using to help you land that dream job turned out to be a phishing attack that stole your identity. Bookmarks are easily organized with the Cyberduck’s drag and drop feature, which can be imported from other programs.Making the decision to leave your current job and seek employment elsewhere can be an exciting time as you imagine how much better your life and career will be when you find that dream job.

Limiting the number of data transfers that are able to simultaneously occur is a further option, and resuming terminated transfers with the software is another feature at the user’s disposal. The user interface’s neatly arranged set-up and intuitive use makes adding new servers a task that can be completed quickly. The program enables an uncomplicated connection to all FTO, SFTP, or WebDAV servers and cloud services, such as Amazon S3, Azure, or OpenStack.

Administrators control the access rights of users who are able to simultaneously access the FTP server.Ĭyberduck is a free FTP program that supports all Windows operating systems from Windows 7 onward and macOS starting with version 10.7. FTP programs let the user sort and manage files into the existing directory structure with speed and ease.
FTP software further assists these solutions by providing a sleek user interface that browser-based clients lack. Those using web-hosting solutions with FTP accounts profit from the quick and easy data transmission between the device and the web server. In passive mode, the server does not receive an IP address from the client (due to a firewall, for example) and offers the client a port through which a connection can be established. This process informs the server which port the client can be reached on. In active mode, the client, which uses port 1023, signals its IP address through port 21 during connection buildup. At this point, it’s important to differentiate between two different types of transfer modes. Following this, the data is transferred through another port.
This FTP client creates a TCP connection to the control port of the server (normally port 21) and is then able to send commands that the server subsequently answers. In order to reach an FTP server, a connection through an FTP client first needs to be established.
