BIOS Boots What? Finding Evil in Boot Code at Scale!

Malware continues to take advantage of a legacy component of modern systems designed in the 1980s. Despite the cyber threat landscape continuing to evolve at an ever-increasing pace, the exploitation of the classic BIOS boot process is still very much a threat to enterprises around the world...

BIOS Boots What? Finding Evil in Boot Code at Scale!

The second issue is that reverse engineering all boot records is impractical. Given the job of determining if a single system is infected with a bootkit, a malware analyst could acquire a disk image and then reverse engineer the boot bytes to determine if anything malicious is present in the boot...

First-Ever Ransomware Found Using 'Process Doppelgänging' Attack to Evade Detection

Security researchers have spotted the first-ever ransomware exploiting Process Doppelgänging, a new fileless code injection technique that could help malware evade detection. The Process Doppelgänging attack takes advantage of a built-in Windows function, i.e., NTFS Transactions, and an outdated...

SynAck targeted ransomware uses the Doppelgänging technique

The Process Doppelgänging technique was first presented in December 2017 at the BlackHat conference. Since the presentation several threat actors have started using this sophisticated technique in an attempt to bypass modern security solutions. In April 2018, we spotted the first ransomware...

Soldering for Reverse Engineering. Swapping out eSIMs with “normal” SIMs

Sometimes, the mobile devices we work on only have cellular data connections. In those instances, we’re usually pretty interested in trying things like this to get credentials for the APN so we can start snooping around on that. We’re also really interested in monitoring what kind of traffic is...

Malware monitor - leveraging PyREBox for malware analysis

This post was authored by Xabier Ugarte Pedrero In July 2017 we released PyREBox, a Python Scriptable Reverse Engineering Sandbox as an open source tool. This project is part of our continuous effort to create new tools to improve our workflows. PyREBox is a versatile instrumentation framework...

Encryption 101: decryption tool code walkthrough

We have reached the final installment of our Encryption 101 series. In the prior post, we walked through, in detail, the thought process while looking at the Princess Locker ransomware. We talked about the specific ways to narrow down the analysis toward the encryption portions, the weaknesses in...

Solving Ad-hoc Problems with Hex-Rays API

Introduction IDA Pro is the de facto standard when it comes to binary reverse engineering. Besides being a great disassembler and debugger, it is possible to extend it and include a powerful decompiler by purchasing an additional license from Hex-Rays. The ability to switch between disassembled a...
