Rewterz Threat Alert – Coronavirus Campaigns – KBot, Azorult, CoronaVirus Ransomware, MBR Wiper

Severity

High

Analysis Summary

Multiple campaigns are being detected using the COVID’19 theme to target victims. Below is a collective report of these campaigns.

• Corona Maps

Taking advantage of internet users’ increased craving for information about the novel coronavirus, Azorult is being used to target people who are looking for cartographic presentations of the spread of COVID-19 on the Internet. It tricks them to download and run a malicious application that, on its front-end, shows a map loaded from a legit online source but in the background compromises the computer. AZORult is an information-stealing malicious software that collects information stored in web browsers, particularly cookies, browsing histories, user IDs, passwords, and even cryptocurrency keys.

• CoronaVirus Ransomware

Another ransomware called CoronaVirus acting as a cover for Kpot Infostealer is being pushed through a fake web site pretending to promote the system optimization software and utilities from WiseCleaner. With the increasing fears and anxiety of the Coronavirus (COVID-19) outbreak, an attacker has started to build a campaign to distribute a malware cocktail consisting of the CoronaVirus Ransomware and the Kpot information-stealing Trojan. The ransomware shows MBR wiping tendencies. 

• Another Corona related campaign exploits the CVE-2017-11882 vulnerability:

Microsoft Office 2007 Service Pack 3, Microsoft Office 2010 Service Pack 2, Microsoft Office 2013 Service Pack 1, and Microsoft Office 2016 allow an attacker to run arbitrary code in the context of the current user by failing to properly handle objects in memory, aka “Microsoft Office Memory Corruption Vulnerability”. This CVE ID is unique from CVE-2017-11884.
