Plug REVEN to your fuzzing pipeline and take advantage of Timeless Debugging and Analysis
Ever wondered how you could integrate REVEN with your fuzzing pipeline, to automatically record the crashes you find and have them ready for analysis without manual intervention? Fear not, this is actually very easy thanks to the automatic recording API provided by REVEN Enterprise and a small piece of Python!...
Analyzing CVE-2020-15999 with REVEN: Buffer-overflow in libpng in Chrome
In this article, we will present a step-by-step analysis of an exploit for CVE-2020-15999 using REVEN. CVE-2020-15999 is a heap buffer overflow in Freetype allowing a remote attacker to potentially exploit heap corruption via a crafted HTML page. In the process, we will show how REVEN’s timeless features such as...
Announcing REVEN version 2.9
Tetrane is pleased to announce the release of REVEN Enterprise and REVEN Professional 2.9. REVEN is a Timeless Debugging and Analysis (TDnA) Platform designed to go x10 faster & x10 deeper while reverse engineering. Technically, REVEN captures a time slice of a full system execution (CPU, Memory, Hardware events) to...
REVEN Vulnerability Research Automation Demo
Watch the replay of the REVEN Automation Demo event we did on June 18th. It focuses on: Building a fully automated workflow from recording system/software activities to analyzing it for discovery, vulnerability research, fuzzing integration, CVE analysis, etc. Advanced scripting: detecting Use-After-Free and Out-Of-Bounds memory access vulnerabilities. This part is...

Reverse Engineering through trace diffing - several approaches
When doing software discovery or vulnerability analysis, it’s often helpful to analyze the difference between two situations: before/after patches, before/after changing an input, crash/no-crash related to changes in fuzzer-generated inputs, etc. In this article, we will see how two analysis scenarios in REVEN can be compared by diffing their traces...
REVEN Open Demo and Open Lab videos
On March 19th, 2021, we did an Open Demo to present REVEN Timeless Analysis and Debugging Platform and its main features throught demonstrations. We recorded those demonstrations to enable everyone to discover REVEN. The 1h video is accessible below. It gives a good overview of how to: Record a trace...
Success Story - How 0patch uses REVEN to speed up micropatching
0patch delivers miniature patches of code (“micropatches”) to computers and other devices worldwide in order to fix software vulnerabilities in various, even closed source products. After attending a REVEN Lab, they bought REVEN to speed up their RE activities. Recently they wrote a great article on how they used REVEN...

Recording vulnerabilities related to non-deterministic bugs, crashes or other complex cases
To analyze non-deterministic bugs or crashes, one must be able to observe exactly what happens when the problem occurs. This is a notoriously tedious task when working with a debugger or from logs. However with REVEN, once you capture the exact period of time during which the problem happens, then...
