Crack legacy zip encryption with Biham and Kocher’s known-plaintext attack. Overview A ZIP archive may contain many entries whose content can be compressed and/or encrypted. In particular, entries can be encrypted with a password-based symmetric encryption algorithm referred to as traditional PKWARE encryption, legacy encryption or ZipCrypto. This algorithm generates a pseudo-random stream of bytes (keystream) which is XORed to the entry’s content (plaintext) to produce encrypted data (ciphertext). The generator’s state, made of three 32-bits integers, is initialized using the password and then continuously updated with plaintext as encryption goes on. This encryption algorithm is vulnerable to known plaintext attacks as shown by Eli Biham and Paul C. Kocher in the research paper A known plaintext attack on the PKZIP stream cipher. Given ciphertext and, 12 or more bytes of the corresponding plaintext, the internal state of the keystream generator can be recovered. This internal state is enough to decipher ciphertext entirely as well as other entries which were encrypted with the same password. It can also be used to bruteforce the password with a complexity of nl-6 where n is the size of the character set and l is the length of the password. bkcrack is a command-line tool which implements this known-plaintext attack. The main features are: Recover internal state from ciphertext and plaintext. Change a ZIP archive’s password using the internal state. Recover the original password from the internal state.

ZipExec is a Proof-of-Concept (POC) tool to wrap binary-based tools into a password-protected zip file. This zip file is then base64 encoded into a string that is rebuilt on disk. This encoded string is then loaded into a JScript file that when executed, would rebuild the password-protected zip file on disk and execute it. This is done programmatically by using COM objects to access the GUI-based functions in Windows via the generated JScript loader, executing the loader inside the password-protected zip without having to unzip it first. By password protecting the zip file, it protects the binary from EDRs and disk-based or anti-malware scanning mechanisms. [hide][Hidden Content]]

ZIP Express allows easy look up of ZIP Code, city, state, county, Area Code and time zone by entering a ZIP Code, Area Code, city, state or county. ZIP Express' power goes well beyond this by providing the capability to actually read a ZIP Code from your application (or clipboard) and paste the information directly into your program (or clipboard) in just about any format that you desire. ZIP Express allows you to search by ZIP Code, city, county, state or area code. As you begin to key in your search criteria, potential matches will be displayed allowing you to watch the possibilities be narrowed down as you type. Select just the data that you want to be displayed. For example, if you are not interested in knowing the county or time zone, then simply choose not to view them. The current time for a given area code, ZIP Code or a city in another country can be displayed, allowing you to determine whether you can place a phone call within normal business hours. Large groups of data can be displayed at once and can easily be printed or copied to the clipboard in almost any format you care to create. View the country and city codes needed to call from within the U.S. to a city in another country. Features U.S. Information Contains all 42000+ U.S. ZIP Codes Search by Zip Code, City, State, County or Area Code Display current time for any location in the U.S. - Adjusts for Daylight Saving Time With the ZIP Code information displayed, press the Map button and, with an Internet connection, see a map of that location International Information Contains dialing and time zone information for more than 240 different countries Display the current time for many cities around the world Look up dialing codes to place phone calls to people in cities around the world Automation Auto-paste data and commands directly into your applications via "hot keys" Over 80 assignable hot keys for auto-pasting Built in "Format Calculator" for designing pasting formats When creating formats to be pasted directly into programs, include common keystrokes such as the tab key or backtab key for navigating among fields. Send Data to Printer in any format Copy Data to Clipboard in any format And more! Program Selectable preferences of what data to display View large groups of ZIP Code and Area Code Data Watch data be narrowed down as you type Place in system tray or make it "always on top" ZIP code and area code data updated 4 times a year and is available free by download [Hidden Content] [hide][Hidden Content]]

Features [1] Auto Updater Automatically checks for updates when you start the script, and Downloads and Installs if any update is available so. [2] Utilises the Power of CPU-Cores Can utilise Maximum no. of Cores available. This means increases the process of cracking of zip passwords by opening different processes on different independent cores.

This is a generic arbitrary file overwrite technique, which typically results in remote command execution. This targets a simple yet widespread vulnerability that has been seen affecting a variety of popular products including HP, Amazon, Apache, Cisco, etc. The idea is that often archive extraction libraries have no mitigations against directory traversal attacks. If an application uses it, there is a risk when opening an archive that is maliciously modified, and results in the embedded payload to be written to an arbitrary location (such as a web root), and results in remote code execution.
