Samsung Printer firmware contains a hardcoded SNMP community string - US-CERT Vulnerability Note VU#281284



Here's another Printer Network Backdoor to watch out for...

Don

Vulnerability Note VU#281284

Samsung Printer firmware contains a hardcoded SNMP community string

Original Release date: 26 Nov 2012 | Last revised: 29 Nov 2012

Overview

Samsung printers contain a hardcoded SNMP community string that could allow a remote attacker to take control of an affected device.

Description

Samsung printers (as well as some Dell printers manufactured by Samsung) contain a hardcoded SNMP full read-write community string that remains active even when SNMP is disabled in the printer management utility.

Impact

A remote, unauthenticated attacker could access an affected device with administrative read/write privileges. Secondary impacts include: the ability to make changes to the device configuration, access to sensitive information (e.g., device and network information, credentials, and information passed to the printer), and possibility the ability to leverage further attacks through arbitrary code execution.

Solution

Samsung and Dell have stated that models released after October 31, 2012 are not affected by this vulnerability. Samsung and Dell have also indicated that they will be releasing a patch tool later this year to address vulnerable devices.

Block Port 1118/udp

The reporter has stated that blocking the custom SNMP trap port of 1118/udp will help mitigate the risks.

Restrict Access

As a general good security practice, only allow connections from trusted hosts and networks. Restricting access would prevent an attacker from accessing an SNMP interface using the affected credentials from a blocked network location. (e.g. Using IP filtering and Mac address filtering)

Disable SNMP protocol

Samsung is advising end users to disable SNMPv1, 2 or use the secure SNMPv3 mode until the firmware updates are released.
*Note that the vulnerability reporter has stated that the community string that remains active even when SNMP is disabled in the printer management utility.

Amarok Music Player (I uninstalled from Fedora 14 Locks up and uses to much CPU 11-28-12)

Amarok is an Open Source Music Player. I have use it some, in the Past. But, now it is Locking up, when I try to open it up on my Fedora 14 System. I remember that Amarok has always used too much System Resources for my 1.8GHz Core 2 with 2.5GB of Ram. But, now it is eating up the CPU Resources and wont even start up, after waiting 30 to 60 Seconds. So, I went ahead and uninstalled it. So that I wont forget and try to use it again. And go through the aggravation of figuring out what is wrong again. I did a couple of searched on the Amarok Support Page. But, didn't see my problem. Let me know if you find an answer...

Here's a few Screen Shots of what I uninstalled and what I kept...

Internet Radio Occupies an 80-year-old NMV Radio Case

This is a nice looking Old Radio Updated to Tune in Web Casts...

Don

Florian Amrhein : Radio


This is a nice internet radio I built. It can tune into internet radio stations from all over the world. It's built into the case of an old valve radio and the controls work pretty much the same way they did in radios back then.


(large)

[ View YouTube video ]

Hardware


Vintage valve radio

I bought an old radio off eBay. It's from the 30ies and was manufactured in the UK by "His Master's Voice".

I removed the old electronics and speaker, and left only the wooden case.



Laptop

The core of the radio is an old 10" laptop. I removed the LCD panel from the casing and fitted it with the laptop in a wooden frame. The 10" panel is a bit too large for the 8" window, but it still fits in the radio case.


(large)

Controls

The radio is controlled by two potentiometers (tuning and volume) and a rotary encoder (band). A second rotary encoder isn't currently used.

The controls are connected to a micro controller (ATmega328) on an Arduino Uno prototyping board

About OpenVDB

The OpenVDB library comprises a hierarchical data structure and a suite of tools for the efficient manipulation of sparse, possibly time-varying, volumetric data discretized on a three-dimensional grid. It is based on VDB, which was developed by Ken Museth at DreamWorks Animation, and it offers an effectively infinite 3D index space, compact storage (both in memory and on disk), fast data access (both random and sequential), and a collection of algorithms specifically optimized for the data structure for common tasks such as filtering, CSG, compositing, numerical simulation, sampling, and voxelization from other geometric representations. The technical details of VDB will be described in a forthcoming paper in ACM Transactions on Graphics.

OpenVDB is maintained by DreamWorks Animation and was developed primarily by

  • Ken Museth
  • Peter Cucka
  • Mihai Alden
  • David Hill

Home Theater Subwoofer Build (Tuba HT( with a folded horn enclosure to make the most out of the Sub

Here's an Intricate Designed Home Built Subwoofer, for a Home Entertainment System. It's supposed to sound very good. I used to be a Cabinet Maker. And I've built a few Speaker Boxes for my Cars and Trucks. Nothing this intricate though. But, I have a good idea of how much time and work that this one would take to build. And it looks like it would take more than a Weekend to Build this one. But, it just might be worth the effort...

Home Theater Subwoofer Build - Tuba HT (imgur.com)

[–]baccula[S] 14 points ago

This is a folded-horn tuba design by Bill Fitzmaurice. The shape of the path allows for very high output with relatively low power input. I'm running this off a 300W plate amp with the gain ~ 1/3rd of the way up.

The rule of thumb when building or buying a sub is: small, cheap, loud - pick two. I chose cheap and loud, as a result the dimensions of this beast are 24.5 X 36 X 36. It uses a single 15" driver.

More information and plans can be found at http://www.billfitzmaurice.com/THT.html

Use a Speaker as a microphone (How To)

I use to use my Stereo Speakers as Microphones, back in the 1960's and 70's. I don't remember exactly when I discovered that speakers would work as a Mic. But, I vaguely remember hooking up a Speaker to the Mic Input Jack on my Realistic Cassette Recorder. Just to see what would happen. Back when I was a kid, in the 60's. Later on, in the 70's - 80's. After I was grown and married and had kids of my own. I Hooked up all of my Home Stereo Speakers to my Teac Stereo Recording Cassette Deck. And used them to Stealthily Record all of the sound and everything everyone said in the whole house. It sounded like everyone was down in a Barrel. But, it was easily understandable and allot of fun to play with. I had my Speakers (all 4 of them) spread throughout the house. So, that I could listen to my Zeppelin, ZZTop, Yes and Who, everywhere. I even rigged some toggle Switches, so that I wouldn't have to keep Plugging and unplugging my Speakers (when I wanted to Record). Before I added the Switches. I would have to unplug the speakers from the output on the Stereo and plug them into the Mic Inputs on the Tape Deck. What a Drag, Man... I used some Adapters, that went from RCA to 1/4 inch male, to accomplish the this. Of course I bought all my parts at Radio Shack. The go to place for Electronics, back then. Yes, Kiddies... Once apon a time... Radio Shack was Cool. To us AV and Electronics Geeks, that is!;) Anyway, I still have those Toggle Switches. Which I didn't buy. But salvaged from some 120 volt Parts that I found or took out of something that was in the garage, when I was growing up. I still have a bunch of my old parts. I'm sure I will use them for something cool. Any Day now!;) But, back to the Point of all this... I have always thought. There must be a way to get rid of that Down in a Barrel Sound and make my Speaker Mic's work like a real Metabolic Microphone. That's what they were, in effect. I have also tried out 4ohm Car Speakers and they work well and are very sensitive. The 4 or  5 inch Car Speaker that I used, the last time I tried this. Along with a little old Radio Shack Mixer (this was just about 12 years ago in 1999 or so). Actually made a better sounding recording, than the Home Stereo 8 to 10 inch Speakers. I set it on the Roof and Recorded the Bugs, the Breeze, the Cars on the Highway near by and If anyone was talking I could Record that too. So, I find this How To, with added Electronics and a nice looking Case. Very interesting. Check it out...

SPKR MiK: How to make a microphone from a speaker. by Aud1073cH

Intro

SPKR MiK: How to make a microphone from a speaker.

How to make an inexpensive microphone capable of picking up low frequencies that doubles as a speaker and direct box.

The large diaphragm of this microphone will pick up more of the low frequencies when recording a kick drum or bass guitar.

Sound recording engineers have been using this trick for years, and Yamaha has also made a commercial speaker microphone called the SubKick, that usually retails for around USD$300.

I was able to build this mic for under $20 by "scrounging" various parts out of old junk. Even if you need to buy all the components, you should be able to build this mic for a fraction of the price of the retail version.

This design goes slightly beyond the SubKick, as far as electronics are concerned, with a dual coil design, and internal direct injection (DI) box.

You should be comfortable using a power drill and a soldering iron, and be able to read a schematic diagram. There is a little sewing, but it isn't too difficult.
Step 1

Materials and Tools

Materials

  • 6.5" dual coil woofer speaker (4ohm). I pulled this one from an Altec Lansing multimedia system that had a blown amplifier.
  • 10" drum. Cheap is okay, but you'll want something with lugs that screw into the shell, not springs or T-rods that screw into couplers. I found this one for $2 at a second hand store.
  • Two miniature bungee or elastic cords. I got a 4 pack for $2.50
  • Crimp on terminal rings. I paid $2.50 for a dozen
  • Adjustable hose clamp (the same diameter as the magnet of your speaker). This was about $1.50 at the hardware store.
  • Female mounting flange for 3/8" microphone stand and small bolts to mount it. I got this at Parts Express
  • 2 sq. ft. of speaker grill cloth. Also at Parts Express
  • Thread
  • Male XLR 3pin panel mount connector and mounting screws
  • Two 1/4" TS (mono) female phone jacks (at least one needs a tab for a normalling connection)
  • A six-pole four-throw rotary switch (I scrounged my switch from a 4-way printer "data" switch box), or you can use Mouser part no. 105-SR2921F-34S
  • 100 ohm potentiometer, also called a variable resistor
  • two knobs (for pot and rotary switch)
  • Two DPDT toggle switches (on-on)
  • A SPST toggle switch
  • Resistors: 100k ohm, two 10k ohm, 10 ohm
  • 100nF capacitor
  • 1:1 ratio audio isolation transformer (pulled from a second hand 270-054 I got for $1)
  • metal container to hold and shield transformer, and mounting hardware
  • heat shrink tubing or electrical tape
  • connecting wire. 22ga or 24ga is fine.
  • short microphone stand (another second hand store find)
