DFIR CTF: LightNeuron DLL - Question 8
In relation towards finding the decrypted email. I am wondering about what I am getting wrong from the conditional breakpoint in order to expose all the decrypted strings after the return function After searching up the XOR key location I went to from Ghidra Through the RET function which I thought would expose the strings I ran going to the ret function then after following the process in order to go to the DLL malware and got into the ret function I set the breakpoint and debug restarted However, it kept saying memory address unavailable. such as this also includes setting the CF flag to 0 I am wondering about what I am doing wrong here and where should I dig deeper? Note: used Gemini to help look into possible solutions however, refered to https://www.youtube.com/watch?v=Tc8Wl37uwYc for aid I have also tried to run to the function but for some reason it the instruction keeps catching it and making a return away from the malware by setting breakpoint towards there but I keep getting lost on how I could actually breakdown the return and evasion techniques. Wondering where should I be digging more to learn how to investigate this process despite the amount of returns stopping the function
Struggling to find the IT email on Simulations: BarterTown Delivery
During the last few days, I’ve been stuck on this lab, and I’m not sure what I’m missing. The lab asks us to use OSINT tools and techniques to gather intelligence about individuals to target within the organization, with the goal of testing the awareness of BarterTown’s IT staff and eventually gaining a foothold in the internal network. I’ve been using the information provided by the lab as a starting point for my reconnaissance. The website gives us several employees and their email addresses, but none of them are identified as IT staff. I also found the DNS SOA contact (hostmaster.bartertown.bitnet), but that appears to be a standard administrative DNS alias rather than an actual employee. The mail server does not seem to allow useful anonymous user enumeration, and the other reconnaissance results have not revealed the missing user. Has anyone completed this lab and can give me a hint about where/how the missing target information is supposed to be discovered?

Immersive Labs- Create a detection rule - Google SecOps
a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; } Hello everyone, I hope you can help me. I am currently taking the "Google SecOps Fundamentals: Demonstrate Your Skills" course, and I am stuck on Task 12, where I need to create a detection rule. I have already created the rule, but the lab is not recognizing it or marking the task as completed. The instructions say that I need to create a rule that detects communication with one of the specified domains. I have configured the following rule, but I'm not sure if it is correct. I am not very experienced with Chronicle/Google SecOps, so I am having trouble understanding what I might be missing. Does anyone know what could be wrong or what additional configuration is required for the task to be validated? Any guidance would be greatly appreciated. Thank you! This is the rule I created: rule lumma_c2_iocs { meta: author = "Diana Quezadas" description = "Detect DNS queries to known Lumma C2 IOC domain." severity = "HIGH" events: $e.metadata.event_type = "NETWORK_DNS" $ioc_url = $e.network.dns.questions.name re.regex( $ioc_url, `(?i)^forbidstow\.site$` ) outcome: $domain = array_distinct($ioc_url) $risk_score = 85 condition: $e }
