This cybercrime union uses this new banking malware to abuse the flaw in Microsoft’s popular e-signature verification system. Combing the vulnerability and the computer virus allows them to exploit the malware and steal consumers’ sensitive information. 

“Previous Zloader campaigns, which were seen in 2020, used malicious documents, adult sites, and Google ads to infect systems,” said Check Point Research via its official blog post. 

The giant security firm continued its observation last November 2021 and discovered that it is being used again by the Malsmoke hacking group. 

Zloader Banking Malware’s Severity 

According to ZDNet’s latest report, the new banking malware has already affected around 2,100 people in different countries. The majority of the victims are in the United States, India, and Canada.

As of the moment, CPR said they see the malicious campaign in around 111 countries. When Zloader was first discovered, malicious actors were using it to exploit Trojan viruses to steal banking credentials. 

Because of this, it was closely connected to other ransomware models. On the other hand, Check Point Research works using a legitimate remote management software called Atera. 

Zloader uses this system as a springboard to infect other systems. If you want to see more details about this new banking malware, you can check this link.   

Microsoft E-Signature Verification’s Flaws 

CPR’s security experts confirmed three vulnerabilities in Microsoft’s e-signature verification tool that are being exploited by the new banking malware. 

These include the following: 

  • CVE-2020-1599
  • CVE-2013-3900
  • CVE-2012-0151

Microsoft explained that updates to fix these flaws were already released. However, they are not installed by default. This means that consumers who will not download the updates manually will certainly be affected by the new computer virus. 

In other news, another malware called RedLine was able to breach more than 400,000 accounts. Meanwhile, T-Mobile’s system was recently breached using the so-called sim swapping method.
