FLARE Script Series: Automating Objective-C Code Analysis with Emulation

This blog post is the next episode in the FireEye Labs Advanced Reverse Engineering FLARE team Script Series. Today, we are sharing a new IDAPython library – flare-emu – powered by IDA Pro and the Unicorn emulation framework that provides scriptable emulation features for the x86, x8664, ARM, and...

Cmd and Conquer: De-DOSfuscation with flare-qdb

When Daniel Bohannon released his excellent DOSfuscation paper, I was fascinated to see how tricks I used as a systems engineer could help attackers evade detection. I didn’t have much to contribute to this conversation until I had to analyze a hideously obfuscated batch file as part of my job on...

FLARE VM is the first of its kind reverse engineering and malware analysis distribution on Windows platform. Since its introduction in July 2017, FLARE VM has been continuously trusted and used by many reverse engineers, malware analysts, and security researchers as their go-to environment for...

2018 Flare-On Challenge Solutions

We are pleased to announce the conclusion of the fifth annual Flare-On Challenge. The numbers are in and we can safely say that this was by far the most difficult challenge we’ve ever hosted. We plan to reduce the difficulty next year, so it may be that the 114 people who solved this year’s...

FLARE Script Series: Reverse Engineering WebAssembly Modules Using the idawasm IDA Pro Plugin

Introduction This post continues the FireEye Labs Advanced Reverse Engineering FLARE script series. Here, we introduce idawasm, an IDA Pro plugin that provides a loader and processor modules for WebAssembly modules. idawasm works on all operating systems supported by IDA Pro, and can be obtained...

CVE-2018-11074

RSA Authentication Manager versions prior to 8.3 P3 are affected by a DOM-based cross-site scripting vulnerability which exists in its embedded MadCap Flare Help files. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim application user to supply...

Dell EMC RSA Authentication Manager Cross-Site Scripting Vulnerability (CNVD-2018-20085)

Dell EMC RSA Authentication Manager is a centralized suite of binary authentication software from Dell, Inc. The software centralizes the management of binary identities, security tokens, methods and users across physical sites. A cross-site scripting vulnerability exists in the MadCap Flare Help...

Loading Kernel Shellcode

In the wake of recent hacking tool dumps, the FLARE team saw a spike in malware samples detonating kernel shellcode. Although most samples can be analyzed statically, the FLARE team sometimes debugs these samples to confirm specific functionality. Debugging can be an efficient way to get around...

New FakeNet-NG Feature: Content-Based Protocol Detection

I Matthew Haigh recently contributed to FLARE’s FakeNet-NG network simulator by adding content-based protocol detection and configuration. This feature is useful for analyzing malware that uses a protocol over a non-standard port; for example, HTTP over port 81. The new feature also detects and...

2017 Flare-On Challenge Solutions

Another year, another successful Flare-On Challenge. I’d first like to thank our challenge authors for their hard work developing each of the challenges, and also for writing up their solutions: Challenge 1: Dominik Weber @Invalidhandle Challenge 2: Nhan Huynh Challenge 3: Matt Williams...

Announcing the Fourth Annual Flare-On Challenge
