One question I was asked when I demo'd creating two PHP files with the same hash is; does it work on compiled binaries?| Nat McHugh
A while ago a lot of people visited my site (~ 90,000 ) with a post about how easy it is to make two images with same MD5 by using a chosen prefix collision. I used Marc Steven's HashClash on AWS and estimated the the cost of around $0.65 per collision.| Nat McHugh
Encryption and hashing are very similar types of data manipulation, but they are used for different types of use cases. Read on to learn the difference!| Encryption Consulting
Introduction I recently had a case involving Discord where the case investigator had observed images within the thread on an iPhone but they were not appearing in the threads in Cellebrite Physical Analyzer. The investigator described the images to me and I was able to locate them in a folder associated with Discord so I ...

Last year we published a proof-of-concept tool to demonstrate bypasses against security products that still rely on the obsolete MD5 cryptographic hash function.| Silent Signal Techblog
MD5 is known to be broken for more than a decade now. Practical attacks have been shown since 2006, and public collision generator tools are also available since that time. The dangers of the developed collision attacks were demonstrated by academia and white-hat hackers too, but in case of the Flame malware we’ve also seen malicious parties exploiting the weaknesses in the wild.| Silent Signal Techblog
I found a way to use the built-in crypto functions to hash files on Windows systems using PowerShell. Paste the following lines into the PowerShell prompt, and specify one or more files when you run md5sum or sha1sum.| and1equals1.blogspot.com
