Rewterz Threat Alert – WinRAR ACE Vulnerability Exploited Through Malspam to Install Backdoor
February 26, 2019Rewterz Threat Advisory – CVE-2019-6974 – Linux Kernel KVM “kvm_ioctl_create_device()” Use-AfterFree Vulnerability
February 27, 2019
Severity
Medium
Analysis Summary
The infection process is almost identical to the previous malspam campaign. The only difference is that the previous campaign had a ZIP archive attached to the malspam email, whereas this new campaign uses a link in a PDF attachment to retrieve the ZIP archive. Within the downloaded ZIP archive is a JavaScript file that infects vulnerable hosts with the Shade ransomware. Files are encrypted by the ransomware and payment via TOR is demanded in exchange for decryption.
Impact
File encryption.
