Google Finds Internet Explorer Zero-Day Exploited in Targeted Attacks

An out-of-band update released by Microsoft on Wednesday for its Internet Explorer web browser patches a zero-day vulnerability exploited by malicious actors in targeted attacks.

Microsoft has credited Clement Lecigne of Google’s Threat Analysis Group for reporting the vulnerability, but neither Microsoft nor Google have shared any details about the attacks involving the flaw.

The security hole is tracked as CVE-2018-8653 and it has been described as a remote code execution vulnerability related to how the scripting engine used by Internet Explorer handles objects in memory.

“The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user,” Microsoft explained in an advisory. “An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.”

According to the tech giant, an attacker can exploit the vulnerability by getting the targeted user to visit a specially crafted website using Internet Explorer. The victim can be lured to the malicious site using social engineering tactics. ..Read More..
