2 min read

eSentire Threat Intelligence is aware of public reports indicating CVE-2018-8174 (a.k.a. Double Kill) has been integrated into web browser exploit kits. eSentire Threat Intelligence assesses with medium confidence that this development poses an immediate threat to organizations where unpatched versions of Microsoft Windows 7 operating system are actively employed.

Additional information

Double Kill is a remote code execution vulnerability leveraging memory corruption inside Microsoft VBScript Engine.2

On May 25, 2018, security researcher Kafeine reported in a blog post3 that proof-of-concept code for CVE-2018-8174 against Internet Explorer 11 on Windows 7 had been integrated with web browser exploit kits. The post includes evidence that this proof-of-concept code has been integrated with the RIG exploit kit as of May 25. eSentire has not observed this activity across our customers.

RIG, like other exploit kits, first determines the vulnerabilities associated with the victim’s browser before redirecting them to the desired exploit. Successful exploitation can result in the installation of malicious code on the victim’s machine. Exploitation typically occurs without user interaction, and victims are often redirected silently from popular websites that have been compromised.
