Tool to simulate fake processes of analysis sandbox/VM software - Fake Sandbox Processes (FSP)

Read

This small script will simulate fake processes of analysis, sandbox and/or VM software that some malware will try to avoid. You can download the original script (made by @x0rz ) in the orig directory.

You can also download my slightly optimized script in the main directory. The file is named fsp.ps1.

Script-Features

Some (good) spyware will stop spying on you as long as the processes run, which are created by this script.
Requirements: Powershell (preinstalled on Win 7 and newer)
Runs on every Windows since Vista
Tiny size
No CPU load
Easy to use
No network connection required

Installer-Features

Automatically install the script to your autostart directory
Extremely easy to install
Uninstaller to purge all files
NO requirements
Tiny size
Offline package
Automatic updater included - only if you want!

Usage:
Open the command line and paste this command (don't forget to adjust the path!):

Powershell -executionpolicy remotesigned -File "Your\Path\fsp.ps1"

After pressing ENTER you will be asked to either start or stop all processes.

Autostart
If you execute the powershell script with the above command, you will have to rerun it after every login or startup. In order to autostart the script I made an easy-to-use installer.

Download the fsp-installer.bat file from the release section.
Double-click it.
Now you will see this cmd window:

Choose "i" to start the installer.
Now enter "y" to start installing or "n" to abort.
If you entered "y" this image will now pop up:

Enter "y" to install the auto-updater or "n" to not install it (it'll work anyways, but it is recommended to install the updater).

You can now close the window or press any key to close it. The (un)installation is complete.

Uninstall
If you no longer want this program on your computer, you'll need the fsp-installer.bat file again. Run it and chose "u" to start the uninstallation process. Then enter "y" if you are ready to uninstall it.

If the process was successful, you'll see a confirmation screen.

Successfully tested on the following Windows versions:

Win 10 Professional
Win 8.1 Home

Collection Package Ramsonware, Malware, BotNet - Pr1v8 Source Code Leaked

Read

Please note, I am not responsible for your actions.

Ransomware is a type of malicious software from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as Ukash and Bitcoin are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

A remote administration tool (RAT) is a piece of software or programming that allows a remote "operator" to control a system as if they have physical access to that system. While desktop sharing and remote administration have many legal uses, "RAT" software is usually associated with criminal or malicious activity. Malicious RAT software is typically installed without the victim's knowledge, often as payload of a Trojan horse, and will try to hide its operation from the victim and from security software

Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that the person using the keyboard is unaware that their actions are being monitored. Keylogging can also be used to study human–computer interaction. Numerous keylogging methods exist: they range from hardware and software-based approaches to acoustic analysis.

Stealers the term info stealer is self-explanatory. This type of malware resides in an infected computer and gathers data in order to send it to the attacker. Typical targets are credentials used in online banking services, social media sites, emails, or FTP accounts.

WannaCry Ransomware Decryption Tool - WanaKiwi

Read

If your PC has been infected by WannaCry – the ransomware that wreaked havoc across the world last Friday – you might be lucky to get your locked files back without paying the ransom of $300 to the cyber criminals.

Adrien Guinet, a French security researcher from Quarkslab, has discovered a way to retrieve the secret encryption keys used by the WannaCry ransomware for free, which works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008 operating systems.

WannaCry Ransomware Decryption Keys

The WannaCry's encryption scheme works by generating a pair of keys on the victim's computer that rely on prime numbers, a "public" key and a "private" key for encrypting and decrypting the system’s files respectively.
To prevent the victim from accessing the private key and decrypting locked files himself, WannaCry erases the key from the system, leaving no choice for the victims to retrieve the decryption key except paying the ransom to the attacker.

But here's the kicker: WannaCry "does not erase the prime numbers from memory before freeing the associated memory," says Guinet.

Based on this finding, Guinet released a WannaCry ransomware decryption tool, named WannaKey, that basically tries to retrieve the two prime numbers, used in the formula to generate encryption keys from memory, and works on Windows XP only.

Note: Below I have also mentioned another tool, dubbed WanaKiwi, that works for Windows XP to Windows 7.

"It does so by searching for them in the wcry.exe process. This is the process that generates the RSA private key. The main issue is that the CryptDestroyKey and CryptReleaseContext does not erase the prime numbers from memory before freeing the associated memory." says Guinet

So, that means, this method will work only if:

The affected computer has not been rebooted after being infected.
The associated memory has not been allocated and erased by some other process.

"In order to work, your computer must not have been rebooted after being infected. Please also note that you need some luck for this to work (see below), and so it might not work in every case!," Guinet says.

"This is not really a mistake from the ransomware authors, as they properly use the Windows Crypto API."
While WannaKey only pulls prime numbers from the memory of the affected computer, the tool can only be used by those who can use those prime numbers to generate the decryption key manually to decrypt their WannaCry-infected PC’s files.

WanaKiwi: WannaCry Ransomware Decryption Tool

Good news is that another security researcher, Benjamin Delpy, developed an easy-to-use tool called "WanaKiwi," based on Guinet's finding, which simplifies the whole process of the WannaCry-infected file decryption.

All victims have to do is download WanaKiwi tool from Github and run it on their affected Windows computer using the command line (cmd).

WanaKiwi works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008, confirmed Matt Suiche from security firm Comae Technologies, who has also provided some demonstrations showing how to use WanaKiwi to decrypt your files.

Although the tool won't work for every user due to its dependencies, still it gives some hope to WannaCry's victims of getting their locked files back for free even from Windows XP, the aging, largely unsupported version of Microsoft's operating system.

That's Hitting World Right Now Uses NSA Windows Exploit - WannaCry Ransomware

Read

Earlier today, a massive ransomware campaign hit computer systems of hundreds of private companies and public organizations across the globe – which is believed to be the most massive ransomware delivery campaign to date.

The Ransomware in question has been identified as a variant of ransomware known as WannaCry (also known as 'Wana Decrypt0r,' 'WannaCryptor' or 'WCRY').

Like other nasty ransomware variants, WannaCry also blocks access to a computer or its files and demands money to unlock it.

Once infected with the WannaCry ransomware, victims are asked to pay up to $300 in order to remove the infection from their PCs; otherwise, their PCs render unusable, and their files remain locked.

In separate news, researchers have also discovered a massive malicious email campaign that's spreading the Jaff ransomware at the rate of 5 million emails per hour and hitting computers across the globe.

Ransomware Using NSA's Exploit to Spread Rapidly

What's interesting about this ransomware is that WannaCry attackers are leveraging a Windows exploit harvested from the NSA called EternalBlue, which was dumped by the Shadow Brokers hacking group over a month ago.

Microsoft released a patch for the vulnerability in March (MS17-010), but many users and organizations who did not patch their systems are open to attacks.

The exploit has the capability to penetrate into machines running unpatched version of Windows XP through 2008 R2 by exploiting flaws in Microsoft Windows SMB Server. This is why WannaCry campaign is spreading at an astonishing pace.

Once a single computer in your organization is hit by the WannaCry ransomware, the worm looks for other vulnerable computers and infects them as well.

Infections from All Around the World

In just a few hours, the ransomware targeted over 45,000 computers in 74 countries, including United States, Russia, Germany, Turkey, Italy, Philippines and Vietnam, and that the number was still growing, according to Kaspersky Labs.

According to a report, the ransomware attack has shut down work at 16 hospitals across the UK after doctors got blocked from accessing patient files. Another report says, 85% of computers at the Spanish telecom firm, Telefonica, has get infected with this malware.

Another independent security researcher, MalwareTech, reported that a large number of U.S. organizations (at least 1,600) have been hit by WannaCry, compared to 11,200 in Russia and 6,500 in China.

Screenshots of the WannaCry ransomware with different languages, including English, Spanish, Italian, were also shared online by various users and experts on Twitter.

Bitcoin wallets seemingly associated with WannaCry were reportedly started filling up with cash.

The Spanish computer emergency response organization (CCN-CERT) has even issued an alert that warns users of the "massive attack of ransomware" from WannaCry, saying (translated version):

"The ransomware, a version of WannaCry, infects the machine by encrypting all its files and, using a remote command execution vulnerability through SMB, is distributed to other Windows machines on the same network."

It is unclear how the WannaCry ransomware is infecting systems, but obvious attack vector can be phishing emails or victims visiting a website containing malware.

"Power firm Iberdrola and utility provider Gas Natural were also reported to have suffered from the outbreak.," according to BBC.

How to Protect Yourself from WannaCry

First of all, if you haven't patched your Windows machines and servers against EternalBlue exploit (MS17-010), do it right now.

To safeguard against such ransomware infection, you should always be suspicious of uninvited documents sent an email and should never click on links inside those documents unless verifying the source.

To always have a tight grip on all your important files and documents, keep a good backup routine in place that makes their copies to an external storage device that is not always connected to your PC.

Moreover, make sure that you run an active anti-virus security suite of tools on your system, and most importantly, always browse the Internet safely.
