psyb0t Worm Targets Linux Routers

Users of Linux-based routers are being warned of a new worm in the wild which attempts to take control and add their device to a growing botnet. As reported over on vnunet.com on March 25, the ‘psyb0t’ worm was first spotted by security research group DroneBL recently, but may have been spreading since the start of the year.

Designed to brute-force the password of routers running Linux compiled for the RISC-based MIPS chip, including ones running custom OpenWRT and DD-WRT firmwares, the worm takes control of poorly secured devices and joins a botnet which the DroneBL group estimates may have grown to as large as 100,000 compromised devices so far.

Because the worm relies on insecure passwords, or devices which have not been reconfigured from their default settings, the group claims that "ninety per cent of the routers and modems participating in this botnet are [doing so] due to user error." While it is always good advice to choose a very secure password for Internet-facing devices, it is unlikely that anyone reading a security blog needs telling. The payload of the worm is interesting: as well as allowing full remote control of the router via an IRC channel, the malware uses packet inspection techniques in an attempt to sniff traffic for usernames and passwords to Web sites and e-mail accounts. The worm also attempts to resist disinfection by locking out telnet, SSH, and Web access to the device’s management functionality — preventing the device from being flashed with a known-clean firmware. The group notes that "this is the first known botnet based on exploiting consumer network devices, such as home routers and cable/dsl modems" and warns that "many devices appear to be vulnerable."

My pedigree and bona fides are published elsewhere. That said, I respect that a few may wish to learn more about the private person behind the writing.  While I accept I am exceptionally introverted (tending toward the misanthropic), I do enjoy socializing and sharing time with like-minded individuals. I have a zeal for integrity, ethics, and the economics of both interpersonal and organizational behavior.

The product of multi-generational paternal dysfunction, I practice healthy recovery (sobriety date December 11, 2001).  I am endogamous in my close personal relationships and belong to a variety of tribes that shape my worldview (in no particular order):

☯ I participate in and enjoy most geek culture. ☯ I am a practicing Buddhist and a legally ordained minister. I like to believe that people of other spiritual/faith systems find me approachable.  I am a member of the GLBTQA community -- I married my long-time partner in a ceremony officiated by Jeralita "Jeri" Costa of Joyful Joinings on November 18, 2013, certificated in King County, Seattle WA. We celebrate an anniversary date of February 2, 2002.  I am a service-connected, disabled, American veteran (USAF).  I am a University of Houston alumnus (BBA/MIS) and currently studying as a post baccalaureate for an additional degree in Philosophy and Law, Values, & Policy.  I am a retired Bishop in the Church of Commerce and Capitalism; the story arch of my prosecuting and proselytizing the technological proletariat is now behind me.  I am a native Houstonian (and obviously Texan).  At 50 years old, I am a "child of the sixties" and consider the 80's to be my formative years.

As I still struggle with humility, I strive to make willingness, honesty, and open mindedness cornerstones in all my affairs. Fourteen years of sobriety has taught me that none of "this" means a thing if I'm unwilling, dishonest, or close minded.  Therefore I work hard on the things I believe in --

  • I believe we can always achieve more if we collaborate and compromise.
  • I believe that liberal(ism) is a good word/concept and something to be proud to support.  The modern, systematic corruption of liberal ideas is a living human tragedy.
  • I believe in a worldview founded on ideas of liberty and equality. The pragmatism of this site and my journey is rooted in both classical and social liberalism.
  • I believe in democratic elections and institutions including a media free of commercial and governmental bias.  Liberty and equality perish when a society becomes uneducated and/or ill-informed.
  • I believe in diversity of life and ideas.  Life and ideas can only flourish when the gene pool is vast and abundantly differentiated.
  • I believe in advancing balance in civil, social, and privacy rights such that all of humanity is continuously uplifted.
  • I believe in separation of church (spirituality) and state (governance) -- with neither in supremacy nor subjugation.
  • I believe in private (real or tangible) property explicitly excluding ideas, knowledge, and methods; such non-tangibles, by natural law, being free for all humanity and emancipated at conception.

While change and the uncertainty of the future may be uncomfortable, I do not fear the unknown; therefore:

    • I believe I must be willing to make difficult choices, that those choices may not be all that I desire, and that such may result in undesirable (or unintended) consequences;
    • I believe we must be willing to make mistakes or be wrong; and I am willing to change my mind if necessary.
I undertake to abide the five precepts of Buddhism; therefore:
  1. I believe it is wrong to kill or to knowingly allow others to kill.
  2. I believe it is wrong to steal or to knowingly allow others to steal.
  3. I believe in abstention from sexual misconduct.
  4. I believe it is wrong to lie or to knowingly allow others to lie.
  5. I believe in abstention from non-medicinal intoxicants as such clouds the mind.

Suicide, major depression, borderline personality, and alcoholism are feral monsters ever howling at my doorstep. However, despite my turbulent and tragic past, rare is the day where I have to rationalize, defend, or justify the actions of that person I see looking back at me in the mirror...

Network neutrality is the principle that Internet users should be in control of what content they view and what applications they use on the Internet. The Internet has operated according to this neutrality principle since its earliest days. It is this neutrality that has allowed the internet to innovate and grow. Without equal access the internet dies.
