New Linux Trojan Is A DDoS Tool, a Bitcoin Miner, and Web Ransomware (softpedia.com)

An anonymous reader writes: A trojan that targeted Drupal sites on Linux servers last May that was incredibly simplistic and laughable in its attempt to install (and fail) web ransomware on compromised websites, has now received a major update and has become a top threat on the malware scene. That trojan, named Rex, has evolved in only three months into an all-around threat that can: (1) compromise servers and devices running platforms like Drupal, WordPress, Magento, Jetspeed, Exarid, AirOS; (2) install cryptocurrency mining in the background; (3) send spam; (4) use a complex P2P structure to manage its botnet; and (5) install a DDoS agent which crooks use to launch DDoS attacks.

Worse is that they use their DDoS capabilities to extort companies. The crooks send emails to server owners announcing them of 15-minute DDoS tests, as a forewarning of future attacks unless they pay a ransom. To scare victims, they pose as a known hacking group named Armada Collective. Other groups have used the same tactic, posing as Armada Collective, and extorting companies, according to CloudFlare.

    After all, you have millions of people looking over source code, so any bugs and vulnerabilities are guaranteed to be found and repaired quickly. This will be fixed quickly and only a few systems will be exploited. On Windows, however, this would be crippling, spreading to many millions of systems while Microsoft waited a month or two to issue a fix. This isn't a story because open source software is guaranteed to be fixed quickly.

      The ignorant here is you and massively so. First, this is about what to do once a vulnerability is known. You, know, the time when it becomes really, really dangerous to leave it unfixed because all the script-kiddies start attacking it. And then, whoever said anything about you having to come up with patch yourself? That is the closed-source mind-set where every modification of software is almost a criminal act, to be committed in solitude and secrecy. Yes, somebody has to come up with a patch, and there are people out there that have a lot better skills at this than you (and yes, I mean you specifically) and can do it, and that still do not work for the vendor. If any one of them publishes a patch, the worst you have to do is verify it solves the problem, but even that is in basically all cases replaced by peer-review among those that have the required skills. This process works and has worked for decades. It is the main reason Linux exists.

      Your hostility towards open source does one thing: It makes you look very, very stupid. It also makes you look like somebody that enjoys being at the mercy of a vendor, like a good little follower that submits to authority because that obviously is how one must live.

      I agree. Open source and Linux should never be criticized. Any criticism is false and, therefore, is yellow journalism. I find any criticism of Linux to be highly offensive and indicative of spamming from paid Microsoft trolls.

      Way to mix issues here.

      1/ Should open source or Linux be criticized? Hell yes, if there are reasons to.

      2/ You conflate Linux and open-source. They aren't the same issues - they aren't even the same thing. Open-source is a development and business model and Linux is a fucking kernel.

      3/ Drupal is to be critized here. Not Linux. Linux as a kernel is doing what the flawed middleware on top of it tells it to. No more, no less. Show me a Linux kernel exploit and I'll be the first to criticize Linux. But in this case, it ain't the culprit.

      I can sort of understand people mixing up GNU things and the Linux kernel, because it's been done for years, and people grew tired of hearing Stallman repeat "it's not Linux, it's GNU/Linux" a long time ago. But Drupal has never been remotely connected to Linux. What next? Run Drupal on FreeBSD and claim FreeBSD has been owned by a trojan?

      This isn't a problem of the "widespread deployment of shitty PHP and Java apps". The vulnerability which this Trojan exploits is CVE-2014-3704 and was patched by Drupal Security Team on the 15th of October in 2014

      The circumstances and agents which have led to this Trojan exploiting Linux systems and Drupal frameworks in the wild is, as with many such things, are multiple and varied. They include installations that are underresourced, shops with critical dependencies that cannot easily upgrade, web apps that at first and second glance do not have interfaces outside an intranet, etc. etc. and so on and so forth

      The key is to stop pointing fingers and laying blame, unless the fingers point to the creators and distributors of the malware. The exploitation and abuse of computer infrastructure is part of territory. Blaming failures on the vulnerable is a sysadmin's version of victim-blaming and does little to mitigate the problem and much to generate community dysfunction.

      Instead of finger pointing, spread the word, inform your unknowing and unwitting colleagues, train junior developers about how to remain secure for multiple computing environments with complex layers of computing infrastructure.
