Evading detection while continuing with the infection process is one of the primary goals of all malware attacks. Lately, threat actors have come up with sophisticated propagation processes to distribute different malware. The infamous Roaming Mantis threat actor group is found using whitelisting to spread new malware families, Fakeecop and Wroba.j, with the purpose of stealing more funds.

On the other hand, the notorious Remcos RAT is leveraging the deadly COVID-19 threat to spread across victims’ systems. Cybercriminals are using CoronaVirusSafetymeasure_pdf.exe to trick victims into downloading the malicious payload.

The past 24 hours saw Cisco patching eleven ‘high’ to ‘medium’ severity vulnerabilities found in its UCS Manager, FXOS, and NX-OS software. The most severe flaw, that can allow attackers to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device, exists in FXOS, and NX-OS software.
