Has anyone figured out the final question of the Ransomware: TeslaCrypt lab? "What is the domain of the first DNS request made after executing the malware?" No correct answers via Ghidra No answers via ProcMon (suggested in the briefing) I checked the activity in x32dbg - nothing Any ideas? Is the lab broken? As always I might be looking too far...12Views0likes1CommentAre you heading to InfoSec Europe 2026?

Dear community, being a professor at a university, I'm trying to create a group where i can invite students in order to complete the tasks of a laboratory that are important to the subject we are learning. I have had the experience on the past but as I see a lot has changed and I cant find how to do that now. Can someone guide me through process please?56Views0likes1CommentGit Security: Git History
Hi all, I’ve been struggling for a while with the last question on this lab, question 7. Where you need to purge access_keys.json from the commit history and force push changes at the end. I’ve tried so many combinations that I’ve lost count. The most recent, which I don’t understand why it’s not working is: git log --diff-filter=A -- *.json To find the commits. git rebase -i <commit_hash> Then changing to edit in the text editor. git push origin --force To force push my changes. This is just one of many ways I’ve tried. Any help would be appreciated, it’s driving me a little mad haha. Thanks, JP90Views0likes1CommentInfrastructure Hacking: Demonstrate Your Skills – Attacking Web Servers
Can anyone help me with this question: Obtain a reverse Meterpreter session. What is the group ID of the current user? I have used the exploit exploit(windows/smb/psexec) to get the second token. But now I'm confused—don't I have to do a reverse shell? When I run this on the host, I'm the system user again.
