As the initial user, I’ll find creds in the PowerShell history file for the next user.

#Combat arms classic malware zip#

I’ll crack the zip and the keys within, and use Evil-WinRM differently than I have shown before to authenticate to Timelapse using the keys.

It starts by finding a set of keys used for authentication to the Windows host on an SMB share. Timelapse is a really nice introduction level active directory box. This container has a dangerous capabilities, CAP_DAC_READ_SEARCH, which I’ll abuse to both read and write files on the host.Ĭtf htb-timelapse hackthebox nmap windows active-directory crackmapexec smbclient laps zip2john john pfx2john evil-winrm winrm-keys powershell-history htb-pivotapi I’ll abuse the Rocket Chat webhook functionality to get a shell in yet another Docker container. I’ll connect to that and use it to get access as admin for a Rocket Chat instance. From the host, I’ll find a different network of containers, and find MongoDB running in one. From that container, I can SSH into the main host.

There I’ll find creds for the Bolt CMS instance, and use those to log into the admin panel and edit a template to get code execution in the next container. I’ll start by abusing the built-in R scripter in jamovi to get execution and shell in a docker container. Talkative is about hacking a communications platform.

As admin, I get the site source, and find a RCE, both the intended way exploiting a markdown to PDF JavaScript library, as well as an unintended command injection.

#Combat arms classic malware password#

With access as a higher priv user on the website, I get creds to the FTP server, where I find the default password scheme, and use that to pivot to the FTP admin. I’ll show a couple different ways to find a username, by generating tons of valid cookies and testing them, and by using the login error messages to find a valid username. It’s crackable, but I don’t have another user’s name or anything else to fake of value. Noter starts by registering an account on the website and looking at the Flask cookie. During the sleep, I’ll load a malicious library into the jail that hijacks execution, and because the binary is SetUID, I get execution as root.Ĭtf hackthebox htb-noter nmap ftp python flask flask-cookie flask-unsign feroxbuster wfuzz source-code md-to-pdf command-injection mysql raptor shared-object With a foothold on the box, I’ll abuse the sandbox again, this time writing a program that sleeps, and then calls a SetUID binary from outside the jail. I’ll take advantage of two mistakes in the coding to write a binary that escapes the jail and reads the database for the application, including the Django admin password. In the source, I’ll see how the sandbox sets up chroot jails to isolate the malware. The source for the site and the sandbox is also downloadable. The box starts with a website that is kind of like VirusTotal, where users can upload executables (Linux only) and they run, and get back a list of system calls and return values. The entire Scanned challenge is focused on a single web application, and yet it’s one of the hardest boxes HackTheBox has published. From that user, I’ll fetch saved Firefox credentials, and use those to read a LAPS password and get an administrator shell.Ĭtf hackthebox htb-scanned nmap django source-code chroot jail sandbox-escape makefile ptrace fork dumbable c python youtube hashcat shared-object With that I’ll gain access to a high privileged access to the db, and find another password in a backup table. Then there’s a weird file include in a hidden debug parameter, which eventually gets a remote file include giving execution and a foothold. It starts with an SQL injection, giving admin access to a website. StreamIO is a Windows host running PHP but with MSSQL as the database.
