New tool can uncover redacted, pixelated text to reveal sensitive data

Researchers have demonstrated how a new tool can uncover redacted text from documents, potentially exposing sensitive information to nefarious actors.
The tool, called Unredacter, was released by Bishop Fox on February 15.

To demonstrate that pixilation is “a no-good, bad, insecure, surefire way to get your sensitive data leaked”, it was designed to take redacted pixelized text and reverse it back into its reveal the supposedly hidden “clear text”.

In a blog post, lead researcher Dan Petro, who wrote the tool, explained that it was created in order to complete a challenge set by Jumspec, and also due to the use of pixilation being a “pet peeve” of his.

“Sometimes, people like to be clever and try some other redaction techniques like blurring, swirling, or pixilation,” lead researcher Dan Petro wrote. “But this is a mistake.”

He told The Daily Swig: “It’s just not a secure way to redact information,” he explained. “But you see it all the time out there on the internet, often by journalists.

“Clearly the community needed to be convinced that pixilation is bad, and a tool to un-redact is the best way to do it.” The toolPetro explained that assuming one already knows the font type for the original information and of the redacted text, “since the attacker in a realistic scenario would likely have received a full report”, his tool can be used to circumvent common issues when it comes to revealing redacted information.

These issues include character bleed over, when a letter shares more than one pixilation column, variable widths between letters, and font inconsistency, which can all make using an algorithm difficult.

Petro wrote: “…there’s an existing tool called Depix that tries to do exactly this through a really clever process of looking up what permutations of pixels could have resulted in certain pixelated blocks, given a De Bruijn sequence of the correct font.”

“I like the theory of this tool a lot,” he said, but added that it “doesn’t work as well in practice as you’d like”.

The blog post contains more technical detail on how the Unredacter tool was built, as well as a proof of concept.

The researcher added: “Redacted data can be almost anything from passwords in a pen test report to victim names in a criminal report.

“The consequences to insecurely redacting information is highly context-dependent, but generally, someone redacts information because they don’t want it to be read.” See Also: Offensive Security Tool: Stratus Red Team
Are u a security researcher? Or a company that writes articles or write ups about Cyber Security, Offensive Security (related to information security in general) that match with our specific audience and is worth sharing?

hacking: security in practice
How do I get Ciphey to use more cores for decryption?

im trying to crack a hash with ciphey but its taking forever and the process is only using one core.

repo: https://github.com/Ciphey/Ciphey

OS: Arch Linux x86_64 Kernel: 5.16.9-zen1-1-zen CPU: Intel i5-3570K (4) @ 4.500GHz GPU: NVIDIA GeForce GTX 770 Memory: 2310MiB / 15960MiB

FakeLogonScreen - Fake Windows Logon Screen To Steal Passwords

http://4.bp.blogspot.com/-20diIlff9Es/Yd0ernCa4RI/AAAAAAAA8j0/mhGTik-X11w_7sfEWP1_uIorfkCZSpDEwCK4BGAYYCw/w640-h400/fakelogonscreen_1_demo-761682.gif
FakeLogonScreen is a utility to fake the Windows logon screen in order to obtain the user's password. The password entered is validated against the Active Directory or local machine to make sure it is correct and is then displayed to the console or saved to disk.

It can either be executed by simply running the .exe file, or using for example Cobalt Strike's execute-assemblycommand.
Binaries available from the Releases page.

* FakeLogonScreen.exe: Writes output to console which for example is compatible with Cobalt Strike
* FakeLogonScreenToFile.exe: Writes output to console and %LOCALAPPDATA%\Microsoft\user.db

Folders:

* / (root): Built against .NET Framework 4.5 which is installed by default in Windows 8, 8.1 and 10
* DOTNET35: Built against .NET Framework 3.5 which is installed by default in Windows 7

Features

* Primary display shows a Windows 10 login screen while additional screens turn black
* If custom background is configured by the user, shows that background instead of the default one
* Validates entered password before closing the screen
* Username and passwords entered are outputted to console or stored in a file
* Blocks many shortkeys to prevent circumventing the screen
* Minimizes all existing windows to avoid other windows staying on top
