September 1, SecurityWeek – (International) Betabot starts delivering Cerber ransomware. Security researchers from Invincea discovered the Betabot ransomware began carrying out a second-stage payload where the malware delivers the Cerber ransomware on the endpoint of a compromised machine after stealing user passwords in the first-stage, in order for the malware operators to increase their profits. Researchers also found the ransomware was being delivered by the Neutrino exploit kit (EK) and stated the malware avoids detection and analysis through virtual machine awareness and by checking for sandboxes.

September 1, SecurityWeek – (International) Cisco fixes severe flaw in WebEx, small business products. Cisco released software and firmware updates addressing several vulnerabilities in its WebEx Meetings Player version T29.10 for WebEx Recording Format (WRF) files after a COSIG security researcher discovered a critical flaw that could allow an unauthenticated attacker to execute arbitrary code remotely by tricking a user to open a specially crafted file, and a medium severity vulnerability that could allow an unauthenticated attacker to remotely crash the program by convincing the user to access a malicious file. Cisco also released fixes for three denial-of-service (DoS), cross-site request forgery (CSRF), and cross-site scripting (XSS) issues plaguing its Small Business 220 Series Smart Plus (Sx220) switches that could allow a remote, unauthenticated attacker to gain access to Simple Network Management Protocol (SNMP) objects on a compromised device.
