I still find it funny that quite often people goes for paid products with fancy presentations and unnecessary black-box automations. We use OpenSSH sftp with Linux access control and rarely do we have to worry about random 10/10 RCEs.

[@CZghost]

That's just Apple's ecosystem. All it is is just a shiny polished shit.

[@mu11668B]

@@CZghost Microsoft has been doing it for years too.

[@morgannelson5756]

Familiar with CVE-2024-33663?

[@Napert]

can we like calm the fuck down with all the vulnerabilities this year?

[@fokyewtoob8835]

[@carsonjamesiv2512]

🤣😂

[@BillAnt]

Exploits and vuln are found almost every day. What's different lately, which has nothing to do with April in particular, is that more of them are being published on KZbin, so it seems like a whole lot of them all of a sudden. More and higher bug-bounties are also a factor. ;)

[@trisnguyen4625]

Thanks for the demonstration. Very helpful !!!

[@BakersBuilds23]

Great Vid!

[@juandig]

Flare doesn't show their pricing on their website... I hate that

[@crashtfa]

They charge based on identifiers, we pay for flare and we get 1000 identifiers and pay 36k a year

[@deidara_8598]

April has been a crazy month, so many criticals

[@Palmit_]

Flare looks very interesting. however, the pricing is elite and well crafted 0-day. I ain't buyin to something even for a trial to find out it's extortionate pricing. the FREE trial is not free. They should be open with their pricing.

[@kettlestew]

Nice "enterprise grade" software you got there.

[@xenostim]

shodilly reinventing the wheel?

[@kintag4459]

Thank you

[@pixl_xip]

*another* vulnerability this april‽‽

[@pepesreal]

i swear theres a vulnerability every day now XD

[@xCheddarB0b42x]

A lot more than one!

[@hgvhjfcjdudrsxhxj]

hey i have a question Jhon, what virtual machine manager u use Vb or vmware?

[@TheMAZZTer]

This is nuts. It seems like they don't have a proper security model in place if it's just that easy. Also the CrushFTP desktop UI doesn't instill me with confidence lol. At least the web UI looks decent.

[@wildstorm74]

Buddy, you shouldn't be surprised.😒 All the (professionals) do is sit on their ass and enjoy getting paid for nothing... until their business that they just so happened gets hacked. Then they actually do something, only to realise that they got hacked by the simplest of exploit/s.🤦 Zero of them don't do extra research, until to fucking late.😑

[@SpectralAI]

Having inside information on this one I can only laugh, and laugh, and laugh. There are more vulnerabilities. You just haven't found them yet. 😂

[@mangodude-nq6su]

Classic closed-source tomfoolery

[@skellybin]

Chill, I was expecting you wise ahh comment

[@SpectralAI]

@@mangodude-nq6su well having seen that source, trust me, you’re better off.

[@Daveychief23]

Sec researcher here - any info you can drop without breaching NDAs?

[@SpectralAI]

@@Daveychief23 No NDA but common decency prevents me from trashing a former colleague. Plus I have a competing product that makes his look like a child’s toy.

Dang right! Such a genuine dude.

[@hamzarashid7579]

I'm surprised that you didn't talked about Linux XZ malware.

[@akashaki11]

Hello @john hammond, recently my Discord was hacked by someone who used it to send phishing links in the NahamSec general discussion group. I’ve resolved the issue, but now I’m unable to rejoin your Discord. Could you please allow me back in?

[@Rachaelshaw7]

Hi! If you can please create a video on the brokewell malware thx 😊

[@userou-ig1ze]

So why would anyone use crushFTP?

[@goodthingforall8973]

April and its vulnerabilities 😂

[@dukeofwelington]

John are you going to be in the people's call center this year?

[@CesSanchez]

Hi, I don't know how to send this to you, but are you aware of the Sabrent situation? They're apparently hosting malware as legitimate firmware updates in their web. Maybe a video could help people not to fall on this and make the company finally solve the issue. Thanks a lot, and please excuse me if this is not the right way to reach you.

[@xTwistCinema]

hell yea

[@carsonjamesiv2512]

COOL!

[@0x32_l3git]

another zero day.... im not even surprised at this point

[@HwSystems]

I do not understand enterprise using app developed in Java. It is like using an NES emulator to do your presentation.

[@Oliver-df4zl]

Bruh 💀

[@Lino1259]

Servers will get crushed, get it?

[@nickcarnevalino7462]

cant stand places that have a "start free trial" button with no price given for full ver

[@BurkenProductions]

But no one is using crushftp whats wrong with people

There is no cloud. It's just someone else's computer.

[@LazyPlays_]

am i dumb or did you just not realize that u were able to pretty much do %hostname% which is effectively a command execution? lol

[@_JohnHammond]

%hostname% isn't getting passed to cmd.exe as if it were an environment variable, it is being specifically handled within the application with their custom processing-- so per your question, no, it isn't command execution, and you are dumb. (You said it, not me)

[@fimdy6530]

i just pissed on my wall

[@Olflix]

good for you

[@ExplosiveAnyThing]

Can somebody explain? I dont really understand how it can read a file outside of the virtual machine?

[@dyna.]

Never heard of this software before... Enterprise ready? The vulnerability info on the download page looks like it's written by a kid and the linux installation instructions are just a joke. Custom start scripts? Then scrolling down i see a systemd service file and at first i thought like oh maybe it's not that bad, but then i look at the actual content and they are not just wrapping their script in a systemd service, no it's wrapped in rc.local and the systemd service is to call rc.local...with a "start" argument that is not used, and without a shebang while it's called directly??? Suprised that even works tbh. I was gonna say, what is this 1995? But heck even in 1995 things weren't this amateuristic.

abit too early i guess lmao
