The hide-and-seek game between security experts and threat actors is becoming complicated as the latter continue to refine their evasion techniques. In a concerning revelation, a malware campaign launched against Canada, the U.S., Australia, and some EU countries has come to the light after almost two years. The campaign leveraged fake installers of popular software as bait to distribute malware such as AZORult (later replaced with RedLine stealer), MagnatBackdoor, and a malicious MagnatExtension. In another instance, Emotet came wrapped in Windows App Installer packages that pretend to be Adobe PDF software.

What more? Customers of eight Malaysian banks fell victim to a phishing attack that was circulated via a malicious app masquerading as a housekeeping service. Online retail stores are also at risk of attacks as a new NginRAT comes disguised legit Nginx process.

Top Malware Reported in the Last 24 Hours

Malware distribution campaign discovered
A two-year-old malware distribution campaign has been found targeting users across Canada, the U.S., Australia, and some EU countries. The campaign uses fake installers of popular software as bait to trick users into downloading malware on their systems. The malware includes AZORult (later replaced with RedLine), a MagnatBackdoor, and a malicious MagnatExtension.  

Emotet’s new attack campaign
The Emotet malware is now distributed via malicious Windows App Installer packages that pretend to be Adobe PDF software. These packages are sent through stolen reply-chain emails that appear as a reply to an existing conversation. These replies tell the recipient to ‘Please see attached’ and contain a link to a malicious PDF. 

Malicious app steals banking information
A fake Android app masquerading as a housekeeping service was used to steal online banking credentials from the customers of eight Malaysian banks. The app was promoted through fake websites and social media accounts. Maybank, RHB, Public Bank, and BSN are some of the victim organizations. 

NginRAT targets eCommerce servers
The new NginRAT hides on Ngnix servers to target eCommerce servers in Europe and North America. The RAT is being used to conduct server-side attacks to exfiltrate payment card data from online stores. Hiding on Nginx servers renders the trojan invisible to security solutions.
