According to the authors of this paper: https://www.cise.ufl.edu/~traynor/papers/scaife-icdcs16.pdf (page 2 – 3) , class C is: ransomware reads the original file, then creates a new, independen… Continue reading How does Ransomware encrypt files? [duplicate]
I am trying to understand the FBE Key generation and verification process at every boot. My device is going to be handled without a lock screen (Android 11 with FBE + Metadata Encryption Enabled), so we do not have any password associated … Continue reading Android File Encryption without screen lock
I’m curious about the best encryption algorithm for encrypting my files in 2022? I thought it was a good solution to encrypt my private key with AES-256 but I decided to ask here and choose better algorithm.
If the answer is still AES, whi… Continue reading Strongest symmetric algorithm in 2022 [duplicate]
I’m trying to make a simple encryption tool for Debian-like systems. I would simply hash a password, use it to lock/unlock a file, and it would never be stored on the drive. My dad threw out the idea that a randomly generated hash-like str… Continue reading Encryption key fuzzing for forensics analysts
I got a ransomware called StopDjvu. On my PC, I have found the public key that is used by the malware (maybe RSA hardcoded).
Is it possible to extract the private key from the public key?

I would like to set up a per-file encryption architecture where every file is encrypted with its own key, and each key is encrypted using a master key.
Is there any good articles to read regarding this? Or any advice?
The questions I have … Continue reading How to setup a Per-File Encryption architecture
I often get this question:
I have sensitive data such as system credentials which my web application needs to secure. Some things I can store in a database, but others (like the credentials to access the database itself) need to be stored … Continue reading How do I secure sensitive information like system credentials in a configuration file?
How likely is that the developers of Winrar would intentionally implement a backdoor to decrypt every file created by this program?
Can anyone confirm that there isn’t a built-in algorithm in the program to reveal the IV and KEY, for examp… Continue reading Security of Winrar 2022 – backdoors and encryption security
