GandCrab ransomware never leaves a chance to surprise security researchers. The ransomware, which is often seen in one or the other attacks every month, is now being used to infect Confluence Server. In order to do this, attackers are abusing a critical vulnerability that exists in Atlassian's Confluence collaboration software. The vulnerability is tracked as CVE-2019-3396 and exists in the software’s Widget Connector.
Two new malware were also discovered by security researchers in the past 24 hours. The malware are identified as SMBdoor and Beapy cryptominer. While SMBdoor has been created using DoublePulsar and DarkPulsar exploit kits, Beapy cryptominer relies on DoublePulsar and EternalBlue to spread across corporate networks.
Beapy cryptominer also uses Mimikatz hacking tool to steal credentials from the infected computers. Users from China are mainly affected by this malware. Meanwhile, SMBdoor has been created with an intention to help researchers in detecting and preventing threats in Windows systems.
