Socgholish Malware

Socgholish is a malware variant first discovered in the wild in 2018. The malware acts as a downloader and is delivered via malicious JavaScript injected into compromised websites. Once installed on a computer, the malware can download various other types of malware, including ransomware.

This sophisticated malware variant is associated with the Russian cybercrime group known as Evil Corp. Due to its downloader functionality, it is believed that the group monetizes the malware by selling access to the systems that it infects. For this reason, a Socgholish infection could lead to multiple other malware infections if the group provides access to multiple customers.

How Does Socgholish Work?

Socgholish is a malware downloader that spreads via drive-by downloads on compromised or malicious websites. If a user is tricked into visiting one of these websites, the JavaScript will execute as the page loads. This malicious JavaScript will typically attempt to trick the user into performing a fake browser update after collecting information about their browser. If the user downloads and executes the alleged update, then the Socgholish malware is installed on their computer.

As a downloader, Socgholish is primarily designed to provide initial access to a computer. Once the computer is infected with Socgholish, the malware can download and execute various other types of malware. Socgholish has been known to distribute several different malware variants, including AZORult, DoppelPaymer, Dridex, Gootloader, and NetSupport.

The Threat of Socgholish

Socgholish is a malware variant designed to spread other malware. This means that it can pose various potential threats to an organization depending on the malware variants that it installs on a computer.

After Socgholish gains access to a computer, it uses Windows Management Instrumentation (WMI) to collect information about it. This data is exfiltrated to the attacker and used to determine which malware variants to infect with it.

Often, this results in the computer being infected with ransomware, which poses a significant threat to an organization’s data. Depending on the ransomware variant, the malware might encrypt corporate data or steal and threaten to leak it if the ransom demand is not met.

How to Protect Against Socgholish Malware

Some security best practices that can help to protect against this threat include:

• User Education: Socgholish’s infection mechanism depends on tricking a user into installing a fake browser update. Educating users about these social engineering tactics can help prevent employees from downloading and installing malware on their computers.
• URL Filtering: Socgholish distributes its malware via compromised or malicious websites. URL filtering based on threat intelligence can identify and block attempts by users to browse to URLs known to be associated with this or other malware campaigns.
• Web Security: Socgholish uses malicious JavaScript to induce the user to download and install a malicious browser update. Web security tools can inspect webpages for potential malicious content and prevent users from visiting these malicious or compromised websites.
• Endpoint Security: Socgholish is malware that collects information about a user’s machine and then installs other malware on it. An endpoint security solution should be able to identify and block the malware before it can be installed or cause damage to the system.
• Patch Management : Socgholish or other malware variants may exploit vulnerabilities as part of their installation process. Keeping web browsers and other programs up to date can help to protect them against attack.

Data Security: Socgholish can install other malware variants, including ransomware, that put an organization’s data at risk. Implementing data security best practices – including least privilege access controls and data loss prevention (DLP) – can help prevent.
