Modus Operandi

The malicious Chrome extensions installed on the system execute some very important functions and activities. After installation, extensions run a JavaScript from a separate domain. But, when opened, the file contains jQuery code that is being replaced by attackers to fake the analysis or to stay hidden from detectors. The extensions are capable of reading data from every web page victim is visiting, can steal browser cookies, passwords and can also forward emails from some inauthentic accounts and IDs.

Once the attackers get their hands on personal information of the victim, next step they do is bridge a connection between the infected system and the server. For this, attackers are using RDP (Remote Desktop Services) to stay hidden from the network. And, the list of tools being used to execute this task are also confined to some limits. The list of tools consists KPortScan, PsExec, Mimikatz, NirsoftSniffPass, Nirsoft WebBrowserPassView, etc.

But, still to be on the safe side and to stay secure, there are some user-side preventions that must be implemented. Some of them are:

  1. It is recommended that users check the extensions list on daily basis that are installed on their Google Chrome web browser. And, if any malicious or inauthentic extension is found, remove it manually or you can use some clean up tool to perform the task automatically.
  2. Users are recommended to use firewall security so that it restricts and stop attackers from accessing remote desktop.
  3. Detect and delete suspicious and inauthentic emails and attachments. Make sure the attachment in the mail is an authentic file and good to download or extract. Also, it is not recommended to open any URL attached in emails even if it’s from your contact. If you want to visit the URL, hop in directly from web browser.
  4. Block attachments with file extensions such as:

Exe|pif|tmp|url|vb|vbe|scr|reg|cer|pst|cmd|com|bat|dll|dat|hlp|hta|js|wsf

  1. Create a whitelist of trusted software that you use, so that no unauthorized or third-party software can get its hands-on system information.
