New Backdoor, MadMxShell
Beginning in March of 2024, Zscaler ThreatLabz observed a threat actor weaponizing a cluster of domains masquerading as legitimate IP scanner software sites to distribute a previously unseen backdoor. The threat actor registered multiple look-alike domains using a typosquatting technique and leveraged GoogleAds to push these domains to the top of search engine results targeting specific search keywords, thereby luring victims to visit these sites. The newly discovered backdoor uses several techniques such as multiple stages of DLL sideloading, abusing the DNS protocol for communicating with the command-and-control (C2) server, and evading memory forensics security solutions. We named this backdoor “MadMxShell” for its use of DNS MX queries for C2 communication and its very short interval between C2 requests.
The forgotten malvertising campaign
In recent weeks, we have noted an increase in malvertising campaigns via Google searches. Several of the threat actors we are tracking have improved their techniques to evade detection throughout the delivery chain. We believe this evolution will have a real world impact among corporate users getting compromised via malicious ads eventually leading to the deployment of malware and ransomware. In this blog post, we look at a malvertising campaign that seems to have flown under the radar entirely for at least several months. It is unique in its way to fingerprint users and distribute time sensitive payloads.
Sneaky Amazon Google ad leads to Microsoft support scam
A legitimate-looking ad for Amazon in Google search results redirects visitors to a Microsoft Defender tech support scam that locks up their browser.
Malvertising Used as Entry Vector for BlackCat Actors Also Leverage SpyBoy Terminator
We found that malicious actors used malvertising to distribute malware via cloned webpages of legitimate organizations. The distribution involved a webpage of the well-known application WinSCP, an open-source Windows application for file transfer. We were able to identify that this activity led to a BlackCat (aka ALPHV) infection, and actors also used SpyBoy, a terminator that tampers with protection provided by agents.
Malvertising via brand impersonation is back again
Web search is about to embark on a new journey thanks to artificial intelligence technology that online giants such as Microsoft and Google are experimenting with. Yet, there is a problem when it comes to malicious ads displayed by search engines that AI likely won't be able to fix.
