A Ukrainian security researcher has leaked over 60,000 internal messages belonging to the Conti ransomware operation after the gang sided with Russia over the invasion of Ukraine.
BleepingComputer has independently confirmed the validity of these messages from internal conversations previously shared with BleepingComputer regarding Conti’s attack on Shutterfly.

AdvIntel CEO Vitali Kremez, who has been tracking the Conti/TrickBot operation over the last couple of years, also confirmed to BleepingComputer that the leaked messages are valid and were taken from a log server for the Jabber communication system used by the ransomware gang.

Kremez told BleepingComputer that the data was leaked by a researcher who had access to the “ejabberd database” backend for Conti’s XMPP chat server. This was also confirmed by cybersecurity firm Hold Security.

In total, there are 393 leaked JSON files containing a total of 60,694 messages since January 21, 2021, through today. Conti launched their operation in July 2020, so while it contains a big chunk of their internal conversations, it is not all of them.

Messages leaked over Conti’s siding with RussiaEarlier this week, the Conti ransomware operation published a blog post announcing their full support for the Russian government’s attack on Ukraine. They also warned that if anyone organized a cyberattack against Russia, the Conti gang would[...]

How reliable is Brave Browser Tor option?

Hey, I was wondering if using the tor window feature in Brave is equivalent to using a “real” onion web tor browser? It seems way quicker in loading speed to me. I am no expert at all, was just interested if it might become a thing for daily browsing instead of a vpn, if it advances further.

If Ddos is illegal then what about anonymous

Correct me if I’m wrong but in this cyber war between Russia and Ukraine the anonymous hacker group have been using Ddos attacks, so if they get caught will they be arrested or will an exception be made due to their cause. In my country Ddos is punishable by a jail sentence/ fine. Any insight helps, thanks

Bruteforce metamask password

Hi, a friend of mine lost his metamask password, he has no seedphrase, no private key, nothing.
He can only try to brute force it.
He knows the password is around 15-18 chars and he also knows the first 7 letters. The other chars are either numbers (0-9) or ! or ?.
What would be the best way to bruteforce?

Rustpad : Multi-Threaded Padding Oracle Attacks Against Any Service

Rustpadis a multi-threaded successor to the classic padbuster, written in Rust. It abuses a Padding Oracle vulnerability to decrypt any cypher text or encrypt arbitrary plain text without knowing the encryption key!

Features

* Decryption of cypher texts
* Encryption of arbitrary plain text
* Multi-threading on both block and byte level
* Modern, real-time and interactive TUI!
* No-TTY support, so you can just pipe output to a file
* Supports Web server oracles…
* … and Script-based oracles. For when you need just that extra bit of control.
* Automated calibration of web oracle’s (in)correct padding response
* Progress bar and automated retries
* Tab auto-completion
* Block-level caching
* Smart detection of cypher text encoding, supporting: hex, base64, base64url* No IV support
* Written in purely safe Rust, making sure you don’t encounter nasty crashes

Usage

Using rustpadto attack a padding oracle is easy. It requires only 4 pieces of information to start:

* type of oracle (web/script, see below)
* target oracle (--oracle)
* cypher text to decrypt (--decrypt)
* block size (--block-size) Web mode

Web mode specifies that the oracle is located on the web. In other words, the oracle is a web server with a URL.

For a padding oracle attack to succeed, an oracle must say so if a cypher text with incorrect padding was provided. rustpadwill analyse the oracle’s responses and automatically calibrate itself to the oracle’s behaviour.

rustpad web –help
rustpad-web 1.8.0
Question a web-based oracle
USAGE:
rustpad {web, –web, -W} [OPTIONS] –oracle –block-size –decrypt

CTF players https://s.w.org/images/core/emoji/13.1.0/72x72/1f3f4-200d-2620-fe0f.png who were given a script to run. The target oracle is a local shell script.

Scripts allow you to run attacks against local oracles or more exotic services. Or you can use script mode to customize and extend rustpad‘s features. However, if you’re missing a feature, feel free to open an issue on GitHub!

Log4J-Detect : Script To Detect The “Log4j” Java Library Vulnerability For A List Of URLs With Multithreading

Log4J-Detect is a script “log4j-detect.py” developed in Python 3 is responsible for detecting whether a list of URLs are vulnerable to CVE-2021-44228.

To do so, it sends a GET request using threads (higher performance) to each of the URLs in the specified list. The GET request contains a payload that on success returns a DNS request to Burp Collaborator / interactsh. This payload is sent in a test parameter and in the “User-Agent” / “Referer” / “X-Forwarded-For” / “Authentication” headers. Finally, if a host is vulnerable, an identification number will appear in the subdomain prefix of the Burp Collaborator / interactsh payload and in the output of the script, allowing to know which host has responded via DNS.

It should be noted that this script only handles DNS detection of the vulnerability and does not test remote command execution.
