hello and welcome to the friday april 18th 2025 edition of the sands internet storm centers stormcast my name is johannes ulrich and today i'm recording from orlando florida today we got another guest diary by one of our undergraduate interns jacob clay camp did write about how to get started in malibu analysis of course we have plenty of diaries always about malibu analysis didier and xavier most notably are heavily contributing to this this is more the beginners view of malibu analysis and sort of how to get started with malibu analysis using a cloud-based system a couple interesting parts here first of all jacob is using aws a free instance and then uses chasm workspaces in order to essentially get a remote desktop into a container which then runs remnux this is lenny seltzer's reverse analysis environment all of this is linux-based and since it is set up in a container it's also easy to reset and the cloud deployment of course makes it nice and isolated from anything that you may have going on in your home network overall interesting setup and then jacob is going over a quick analysis of a red tail sample and how to apply this particular environment to the analysis of this particular matter interesting a write-up and nice step-by-step guide to help you get started and then we have a critical vulnerability affecting the erlang otp ssh library this affects any ssh servers written in this language the vulnerability was found by researchers at the ruhr university city in bochum now the otp here in erlang otp does not stand for one term one-time password instead it does stand for the open telecom platform this particular version of erlang was created and maintained initially by ericsson and is often used in telecom related devices routers and the like so certainly there is quite a number of affected devices out there the cbss score of the vulnerability is a perfect 10.0 because it does allow for arbitrary code execution without authentication the problem is that some ssh messages some ssh protocol messages can be sent and executed before authentication finishes due to this bug and that then leads to execution now the user this this code executes at depends on the user the ssh server is running at at the time it receives these messages definitely upgrade but of course since this is a vulnerability in the library used to create the ssh server you may have to wait for respective vendors to actually release updates here in the meantime the only alternative you have is to disable or firewall the ssh server and belgium security company inviso did release a report with details regarding some of their recent findings of the brickstorm backdoor brickstorm has been used in linux in in sort of vmware environments but now they also found a version of this backdoor on windows there are a couple interesting things to note here unlike most backdoors this backdoor actually does not have a remote code execution capability they say that typically rdp and such is used instead by the attacker and that they specifically didn't include a remote code execution capability to evade some heuristic and behavioral detection that you often find that would flag any code execution behavior instead this particular backdoor is able to read write files from the file system it also has some network components that would allow an attacker to essentially use an affected system as a pivot to scan other systems in the network so certainly a capable piece of malware also interesting as a command control channel they're using cloud flare workers and similar systems that again are less likely going to trigger alerts interesting report and it also includes some good indicators of compromise and the ways and techniques how you can actually find if you are affected by this particular backdoor and openai released its latest greatest model gpt 4.1 but this didn't happen amid some controversy around the security aspects here first of all this model was released without the usual safety reports or system cards which typically outline how this particular model was created to be safe meaning not for example allowing to create malware and apparently some of these safeguards that you often find in these models are missing from gpt 4.1 making it trivial to create malware with this model interesting problem here and not even sure if this will be something that the openai will fix in short notice but definitely we have seen malicious models of course before but not from major vendors like openai well that is it for today so thanks again for listening and thanks everybody who i met here i mean all of you listeners at the event here in orlando and well i'll talk to you again on monday bye

大家好，歡迎收聽2025年4月18日星期五的金沙互聯網風暴中心風暴播報，我是約翰尼斯-烏爾裡希，今天我在佛羅里達州奧蘭多錄製節目。當然，我們有很多關於Malibu分析的日記，其中Didier和Xavier的貢獻最大，這篇日記更像是Malibu分析初學者的觀點，以及如何使用雲系統開始Malibu分析。首先，Jacob 使用 aws 免費實例，然後使用 Chasm 工作區，以便將遠程桌面接入容器，然後運行 remnux，這是 Lenny Seltzer 的反向分析環境。當然，雲部署使其很好地與家庭網絡中發生的
