Citrix Discloses Security Breach of Internal Network (zdnet.com)
Citrix disclosed today a security breach during which hackers accessed the company's internal network. In a short statement posted on its blog, Citrix Chief Security Information Officer Stan Black said Citrix found out about the hack from the FBI earlier this week. From a report: "On March 6, 2019, the FBI contacted Citrix to advise they had reason to believe that international cyber criminals gained access to the internal Citrix network," Black said. "While not confirmed, the FBI has advised that the hackers likely used a tactic known as password spraying, a technique that exploits weak passwords. Once they gained a foothold with limited access, they worked to circumvent additional layers of security," the Citrix exec added. Black said hackers accessed and downloaded business documents, but Citrix wasn't able to identify what specific documents had been stolen at the time of his announcement today.
I know Citrix is a godsend for people who have to deal with Software Deployment and updates. But it is really just a gross hack to make software accessible over the network that were never designed to be such. On most Citrix Setups I am able to get more access to apps that I wasn't given permission for. Mostly due to the fact that Windows security wasn't designed for Citrix in mind. A right click here, view file path, or a help file that opens IE. I now have access to applications on the server that I wasn't really meant to have.
If you think Citrix is a good idea, then you probably should be looking at different software, such as more Web Based (HTML) Application. Because you will be better off.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
... didn't know they had been hacked and, when informed that they were breached, didn't know what the hackers got.
Clueless.
It little behooves the best of us to comment on the rest of us.
They have nothing of value to steal. Must have been a practice attack or somebody that was forced to user their products and wants revenge for that.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
If Citrix used ext4, they would have a log of which files were accessed, and when. Actually Linux provides that information no matter what the file system is. The system administrators must be fairly incompetent not to be able to recapture that information.
For security on a PRIVATE lease-line (e.g. fractional T1 etc.)? More secure vs. "over-the-public web" transit by far. I did a few enterprise class apps in MSVC++, Delphi & VB over Citrix in my time circa 1994-2000 for Fortune 500's on down who used that method & it worked.
* Are there "catch-22"'s vs. "normal code"? Yes. Multi-user ALMOST killed the original project since it was "new to us" (even my senior dev) & the 'fixes' CITRIX provides to 'offset' it didn't work that well - even using "bad-boy user" separate switches JAMMED UP when the load got heavy - so I looked @ how the driver & middleware was done & like MOST ALL DRIVERS? No time-slice back to CPU for "best performance" - yea, until a large multi-user load occurs.
A sleep API call (vs. say Application.Processmessages in Delphi or DoEvents in VB, ODDLY despite they using 'sleep' internally in THEIR code? Didn't work - had to use SLEEP API CALL DIRECTLY in loops).
Cut CPU overuse from 90% lockup on clients down to 1-2%... saved the day.

Password spraying. The big kind.
Powerful. Sophisticated.
That is all.
See subject DOLT: It's for those coding on it in reply to parent it is a GOOD TIP that works unlike YOUR troll horseshit off-topic COMPLETELY you dolt do-nothing UNSKILLED & UNEDUCATED moron... menial!
Do YOU design ENTERPRISE CLASS CODE? I did for damn near 24++ yrs., asshole. That will SAVE projects on CITRIX code to DB engines!
* LOL! I mean, please - just READING your bs made me laugh & clued me into the FACT - you've NEVER done that level of work.
(Clearly, ALSO - You didn't read who I replied to, what they mention & yes I am ALL about the TOPIC in Citrix itself as well, asshole... he spoke of SOFTWARE DESIGN (something way, Way, WAY above your DOLTISH MENIAL so-called 'brain'))
APK
P.S.=> Above all ELSE you fucking know-nothing PEON - grow up! apk
Early Citrix systems were added the feature of changing one's password at login. Just type the password, then "/", then the new password, then "/" (then the new password again? I forget). Anyway, it had the bug where it didn't check that the old password was correct! So, one could log in to the admin account with a password of "//" and gain full access, then change the password using the normal tools once in.
This demonstrates why "blindly adding features" can lead to security risks. There's no good reason to allow users to change their password at login time.

Judging by the comments so far, apparently Slashdot still thinks that Citrix on only does a Windows Remote Desktop product, and doesn't know that Citrix does a whole fleet of products that this breach is very problematic for.
GoToMyPC ... and yes Citrix Virtual Apps And Desktop(formerly XenApp, formerly Citrix terminal server.
GoToMeeting
GoToWebinar
Citrix Hypervisor(XenServer)
Citrix Netscaler Gateway
Citrix Web App Firewall
A Citrix breach is a big fucking deal, especially when it wasn't self-discovered and they don't even know what was accessed yet.

Based on the 'history' with the FBI, we only know One Fact: They Always Lie and catch no one.
Occams razor suggests some FBI chimp did something stupid and the FBI contacted Citrix before Citrix figured it out.
Because that is on par with the rest of the crap we hear about which actually happened, and Citrix probably has nothing that another company would try to steal.
If FBI, CIA, NSA, or homeland security are involved, it is an operation against YOU the citizens.
You Have Never, and Will Never receive any benefit from all the illegitimate government agencies.
