- →Fortinet released a dedicated IPS signature to detect exploitation of CVE-2018-0838 ↗
- →The vulnerability is triggered in chakra.dll; monitor for type confusion in NewScObjectNoCtor when JavascriptNativeFloatArray is converted to JavascriptArray without validation in JIT-compiled code ↗
- →The vulnerable component is chakra.dll; analysis was performed against version 11.00.14393.447 — use this version as a baseline for patch-gap detection ↗
- →The bug is exploitable via a malicious web page browsed through Microsoft Edge; monitor Edge renderer processes for anomalous memory access patterns following JIT compilation ↗
- ·The PoC used in the Fortinet analysis is based on Google Security Research Team published information; no in-the-wild exploit samples or hashes specific to CVE-2018-0838 are provided in the sources ↗
- ·The assembly-level analysis targets a specific chakra.dll build (11.00.14393.447); detection logic tied to this version may not apply to patched or other builds ↗

CVE-2018-0838 [HIGH] Scripting Engine Memory Corruption Vulnerability
Scripting Engine Memory Corruption Vulnerability
Description: A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Microsoft Edge (HTML-based). The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. 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.

An Analysis of the DLL Address Leaking Trick used by the “Double Kill” Internet Explorer Zero-Day exploit (CVE-2018-8174)
By Dehui Yin | August 06, 2018
“Double Kill” is an Internet Explorer(IE) Zero-Day exploit which was discovered in the wild and fixed in the Microsoft May Patch. It exploits a use-after-free vulnerability of vbscript.dll to execute arbitrary code when a vulnerable system browses a malicious web page via IE. Multiple exploit kits have already added this exploit, and it is still active in the wild.
This use-after-free bug causes a type confusion in vbscript.dll, which allows the attacker to access and overwrite the whole user space memory address. However, before the shellcode can be finally executed, the attacker has to get the address o

An Analysis of the Use-After-Free Bug in the Microsoft Edge Chakra Engine (CVE-2018-0946)
By Dehui Yin | June 28, 2018
Microsoft fixed an use-after-free bug in the Edge Chakra Engine in the May 2018 Patch. This bug (CVE-2018-0946) causes the Chakra Engine to access a freed function address that can possibly be exploited to execute arbitrary code when a vulnerable system browses a malicious web page via Microsoft Edge.
This use-after-free bug occurs when the Chakra Engine tries to execute the optimized function code generated by the just-in-time (JIT) compiler, which has already been freed when closing the related context. In this post, the team at FortiGuard Labs looks deeply into the Microsoft Edge Chakra Engine assembly codes to expose the root cause of

By Dehui Yin | May 18, 2018
CVE-2018-0838 is one of the ‘type confusion’ bugs in the Microsoft Edge Chakra Engine that was fixed by Microsoft three months ago. This bug causes memory corruption and can possibly be exploited to execute arbitrary code when a vulnerable system browses a malicious web page via Microsoft Edge.
This type confusion bug occurs when the codes generated by the Chakra just-in-time (JIT) java compiler change the property value of a newly converted JavascriptArray object without validation. In this post, the team at FortiGuard Labs looks deeply into the Microsoft Edge Chakra Engine assembly codes to expose the root cause of this vulnerability.

Only a few days after FortiGuard Labs published an article about a spam campaign exploiting an RTF document, our Kadena Threat Intelligence System (KTIS) has found another spam campaign using an even more recent document vulnerability, CVE-2017-11882. Although the vulnerability has existed for 17 years, according to a report by SecurityWeek, it was only disclosed and patched by Microsoft in the second week of this month.
And as we have repeatedly seen, not long after its disclosure threat actors were quick to take advantage of this vulnerability to deliver a malware using a component from a well-known penetration testing tool, Cobalt Strike.

Recently, FortiGuard Labs found an interesting malware campaign using the recently documented vulnerability CVE-2017-11826 that was patched by Microsoft in October of this year. A detailed analysis of this exploit is also included in this article.
Based on the context of the campaign used to lure victims, as well as how the payload malware behaves, we had a hunch that this was not a common cybercrime campaign and was even possibly a targeted attack on specific institutions or locales. For this reason, we decided to look deeper.
As is common with this type of attack, the command-and-control (C2) server for this campaign

Remcos is another RAT (Remote Administration Tool) that was first discovered being sold in hacking forums in the second half of 2016. Since then, it has been updated with more features, and just recently, we’ve seen its payload being distributed in the wild for the first time.
This article demonstrates how this commercialized RAT is being used in an attack, and what its latest version (v1.7.3) is capable of doing. Remcos is currently being sold from $58 to $389, depending on the license period and the maximum number of masters or clients needed.

By Bill McGee | October 07, 2016
We’re into the final quarter of the year, and the cyberthreat landscape continues to be interesting. This week in the Fortinet Threat Intelligence Brief we looked at a number of interesting trends around IoT botnets, continued ransomware problems – both through directed attacks and infected websites, and the spoofing of the Navy Federal US Credit Union.
One interesting thing to note is how attacks tend to move from target to target and region to region in waves. This week, for example, we saw a near quadrupaling in attempts to deliver a malicious Excel file to deliver the Odin ransomware variant, primarily directed at users in Japan. We also saw a series of attacks aimed at a
