Um. That easy huh? By default files aren’t executable, so it would require changing the permission. It would also need to be run as root to infect the whole system. How about dependencies? How about architecture differences. Just x86 or 64-bits? MIPS? Arm?
So on and so forth. Linux isn’t a monoculture (no pun intended here guys/gals!) like the Windows ecosystem is.

Even a pre-packaged deb (which can be installed ala double click in Ubuntu) would ask for a password, and again, wouldn’t be viable for every Linux distribution out there, architecture not withstanding.

Having to run something out of the blue is odd if you use a package management system. Cryptographically signed, easily installed/uninstalled and updated (and source available for those interested.)

Although maybe I’m alone in the 24,000+ packages available in Ubuntu being enough for regular computer use.

My point here is I’ve unlearned a habit, there is no need to grab software willy nilly off the net. Instead check the repos, and check the source of software. Do you trust it, etc and why should I install this. Plus does it behave like a rootkit, if so then it can be scanned for, if this really does become some sort of popular vector…

So, yes, you could use social engineering to get someone to install something, but the process should set off a red flag in the user.
There isn’t some autorun or double click deal here. For those users that understand binaries are a blackbox, where no one can inspect, change, etc. anything, install at your own risk.

“Some user action was CLEARLY REQUIRED to infect the PC with the CIPAV. In the warrant application, the FBI used the term activate several times and alluded to a spyware plant failure if the target did not trigger the CIPAV through the targeted MySpace account. MySpace accounts can’t receive traditional e-mail, so one hacker standard — attach the CIPAV to a message and hope the recipient is stupid enough to launch it — wasn’t available”

Exactly. If you want to infect a Linux users, it’s as simple as sending them some program and getting them to run it. You also mention Slashdot, but of course, you only mention comments that would be critical of Microsoft. How about these comments instead? Both of which received high rankings.

“What makes you think they don’t have a variant for Linux? User stupidity (i.e: bad/no security) isn’t unique to Windows. Off the top of my head, if they are relying on the web as an infection vector combined with user stupidity, why not write it into a Firefox extension?

Yeah, it wouldn’t get your typical /. geek, but most criminals aren’t known for their foresight or intelligence. “Oh, the private website with the bank account information needs me to install this software! Ok, what could possibly go wrong?”

In response to that:

“This is an excellent statement. Stupidity knows no bounds. Its also dangerous to assume that the FBI doesn’t know what it is doing. When I worked in law enforcement, the FBI computer crimes agents I knew were well versed in operating systems other than Windows. The two I worked with most often had a solid knowledge of Linux and Cisco IOS.”

No, I don’t have details or a link, I remember reading this a while back somewhere, and now can’t remember where.
