TOP VULNERABILITY THIS WEEK: Mozart backdoor uses DNS to communicate with attackers
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Details of new Mozart malware family unveiled
Description: A new malware family known as “Mozart” uses DNS to communicate with a command and control seemingly belonging to its creators. It also evades detection by disguising itself and executing specialized JSScript files. Once infected, Mozart can download other types of malware onto the victim machine, including ransomware and cryptocurrency miners. This malware is typically spread through spam campaigns with malicious PDF attachments. If a victim opens the PDF, it displays a message saying that the PDF reader doesn’t support a specific font, and asks the user to download a font, which actually points to a malicious ZIP file.

TOP VULNERABILITY THIS WEEK: New remote access tool shows connections to other RAT families
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: ObliqueRAT spreads via malicious documents
Description: Cisco Talos has observed a malware campaign that utilizes malicious Microsoft Office documents (maldocs) to spread a remote access trojan (RAT) we’re calling “ObliqueRAT.” These maldocs use malicious macros to deliver the second-stage RAT payload. Network-based detection, although important, should be combined with endpoint protections to combat this threat and provide multiple layers of security. According to Talos researchers, ObliqueRAT has connections to the adversaries behind the CrimsonRAT discovered last year.

Title: Multiple vulnerabilities in Cisco Data Center Network Manager
Description: Cisco Data Center Network Manager contains a privilege escalation vulnerability and a cross-site request forgery vulnerability. Cisco disclosed the high-severity vulnerabilities late last week. In the case of the privilege escalation vulnerability, an attacker could exploit the Network Manager in a way that would allow them to interact with the API with administrator-level privileges. A successful exploit could allow the attacker to interact with the API with administrative privileges.

TOP VULNERABILITY THIS WEEK: Snake ransomware zeroes in on industrial industries
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Snake/Ekans malware adds new functionality to go after ICS
Description: The Snake ransomware (otherwise known as “Ekans”) has added new capabilities aimed at going after industrial industries. Ekans first emerged in December, but now has a relationship with the MEGACORTEX ransomware that could allow it to spread quickly on ICS systems and even force some services to revert to manual operations. The malware’s code now includes direct references to HMI processes and historian clients that are commonly linked to ICS.
