That's not a typo. The paper is actually says, "for pun and fropit". It discusses polymorphic mutation in JScript.

Have deleted opinionated post.

More details have emerged which allegedly depict Mr. Bowie walking around a healthcare facility trying to get access to machines without hospital authorization.

No idea what's going on. All we know is Mr. Bowie should hire a lawyer.

Earlier today we shared some information on a CEO of a cybersecurity company in Oklahoma, United States, allegedly intentionally deploying malware to a healthcare facility in Oklahoma City.

More details have been presented which paint a different picture than what was originally shared and it kind of complicates the issue presented.

Jeffrey Bowie, the Chief Executive Officer of cybersecurity firm Veritaco, had a warrant for his arrest issued by the United States Federal Bureau of Investigation for allegedly intentionally deploying malware to a client of Veritaco (St. Anthony Hospital). Interestingly, the FBI did not immediately notify Mr. Bowie of the arrest warrant — however they DID notify local media new stations. Mr. Bowie was informed of his arrest warrant by friends, family, and colleagues rather than law enforcement themselves.

Mr. Bowie has publicly released the "source code" of the malware allegedly deployed on the healthcare facility (attached image). The "malware" is a powershell script which takes images of the desktop computer every 20 seconds then sends the images back to a remote server owned by Mr. Bowie. The powershell script was deployed onto 2 machines in the healthcare facility and set to run via Windows task scheduler.

Mr. Bowie asserts the endpoint the "malware" sends data to was terminated in August, 2024. Hence, the code present is basically worthless.

1 of the computers (Computer "A") was publicly accessible and specifically designated for guests to use.

The 2nd computer (Computer "B") remained unlocked (???) was designated for sending and receiving PHI (?). Mr. Bowie asserts "unlike Computer A, no software was written."[sic]

Mr. Bowie has (as of this writing) not explicitly stated why the powershell script took screenshots every 20 seconds. Additionally, no details have been shared as to how long this "malware" has been present on machines.

Mr. Bowie asserts local media outlets have defamed his character and has stated he has placed his faith in judicial system and God to deem him not guilty of any wrong doing.

The naming convention "Trojan" easily confuses people i.e. Remote Access Trojan. Unfortunately, due to successful media campaigns, the term Trojan is now closely affiliated to condoms.

Instead we petition to formally change the term to something which is reminiscent of the term "Trojan Horse", and carries the same meaning

Suggestion: Horse

Example(s):

- Remote Access Horse
- Sophisticated Horse
- "... The Threat Actors inserted a Horse payload into the Word document..."

Laymen can easily identify a horse and they will understand the concept of a horse on the loose is very dangerous. You can explain to customers there is a horse loose in their computer and the horse is causing serious damage.

It's so privacy focused, it takes images of what you're doing every 90 seconds to ensure you're not making any opsec mistakes.

It then saves it in a super secure location (APP DATA) so then you can review it later if you want

Hello,

To work in IT and/or cyber security...

You don't like have to like Linux, you don't have to like C (or Assembly), you don't have to like Mr Robot, you don't have to go to conferences or meetups, you don't have to prefer IRC over Discord, you don't have to have a fancy setup

You can like or dislike whatever you want. Don't feel pressured to think or behave a certain way.

Discord CEO stepped down. The new upcoming CEO was previously the CEO of Activision. His resume includes the implementation of micro-transactions in Call of Duty.

Imagine if Discord suddenly introduces micro-transactions, like paying $10/month for unlimited call times 😂

I hate seeing people write and/or say "cyber" in the context of cybersecurity i.e. "I'm studying for cyber right now".

The word "cyber" is an adjective — do you study big, tall, short, tiny, blue, stinky?

Originally the headlines and articles (which presented little information) painted a picture of an Insider Threat potentially aid and abetting Threat Groups.

Now it gives the picture of a misunderstanding and potentially the United States Federal Bureau of Investigation doing a poor job in regards to cybercrime.

Historically we have believed the FBI has done a great job with cybercrime. We have seen them takedown large and sophisticated Threat Groups. In this case (based on the details presented thus far) the FBI of Oklahoma has done a poor job and is chasing a non-issue.

tl;dr sounds like a shit show

We're not lawyers, but we can assert with a high degree of confidence he is about to get absolutely fucked by the United States Federal Bureau of Investigation. They (probably) do not like Insider Threats targeting healthcare

tl;dr long written opinion on being new to cybersecurity, list my experience as a reference to a "jr" role requirement list, show how much of a noob i am, yapping like a yapper

funny_cat_picture_with_caption.png

Non-tldr:

Earlier someone made a comment on one of our posts about requirements for Juniors in cybersecurity. The list was pretty extensive. This isn't a diss to this person, but I strongly disagree with their opinion. Here is what they listed as a requirement to be a Junior in cybersecurity:

• Strong experience in Linux servers and AD
• Must hold at least CCNA, CCNP, CompTIA
• Strong knowledge of cloud computing like AWS, Azure, GCP
• Must have Security+, CEH, CISSP, Cisco CyberOps
• Knowledge of SQL, Oracle db, with Java, Python, C++

If these were required, I wouldn't have a job.

- Never attended a university. Never attended a college. Finished High School (primary school for nerds in UK, EU?) with average grades.

- I use Linux as a daily driver (Ubuntu), and I use Windows 11 for video games and doing C/C++ development. I would not consider myself "strong" in Linux — there are some seriously hardcore Linux nerds. I can use it, I can Google stuff, but I am not "strong" (in my opinion).

- Little to no experience with AD. I've used it in enterprise environments, I'm aware of basic concepts of exploitation of it and lateral movement, but I am nowhere near capable of doing anything serious or important with it. Shoutout the Network and/or System administrators who do stuff with Forests, or something, some buzzword I remember.

- I don't possess any certificates. My understanding of networking is limited to the TCP/IP model (can barely remember OSI model), and basics of headers. My knowledge of networking primarily revolves around using it when programming. I will instantly fail any Cisco related certificate. I can use Wireshark. Am I cool enough?

- I possess little to no knowledge on Cloud computing. I can upload and download files, I can copy and move things, I know how to list files. I know the basics of creating a bucket and doing permissions, but I am by no means an expert. I praise the nerds who do Cloud stuff and DevOps because I think it's boring.

- I've been coding in C for 19 years. I consider myself strong in it. However, I still don't know "everything". I've been studying and/or doing Windows internals stuff for over 10 years. I consider myself "strong", but there are some truly brilliant people who I believe can walk circles around me and make me look like an idiot. There are many, many, many times I realize I have a knowledge gap or make a really obvious and dumb mistake (probably like, every day)

I can code (without using AI like a total dork) in C, C++, Visual Basic .NET framework), C# (.NET framework), Python, AutoIT, Python, x86/x64 MASM, T-SQL. However, my usage of them is varied and many of them I'm extremely rusty.

My opinion is that if you want to do something in cybersecurity, do what you enjoy and do it well. If you want a job you need to apply places, talk to people, get involved, and try hard. You don't need to go to conferences, but cybersecurity is a rapidly evolving field and (similar to Doctors of Medicine), is it profoundly important to remain actively engaged (Continual Education*). Things change daily. You need to be somewhere, doing something, to pay attention and understand what is happening.

Today virus exchange was banned from our (other) hosting provider (Wasabi). They claim our domain virus-dot-exchange has malware on it.

They cited 1 specific file hash and stated virus exchange is disabled until we can explain why we have 1 malware on the server
