If you get your tires rotated regularly but there is still a significantly uneven tread on them you should have your wheel bearings and shocks/struts checked.

The other danger is salt and dirt on the road. Salt will wear out your seals, allowing dirt to sneak into your wheel bearing. These contaminants can compromise the lubricant, which is necessary to prevent too much friction. Over time this will cause wheel bearing failure. If you consistently drive in poor road conditions you will need to have your wheel bearings checked sooner than the average vehicle.

[FX] from Phenoelit gave an entertaining talk about barcode security. He covered both how the systems are implemented and how they’ve been exploited. The first example was a parking garage in Dresden that issues non unique barcodes for the unlimited passes that hotels give out. Anyone code print out an image of that particular code and park for free. German grocery stores have automated machines that refund you for your empty beer bottles. The barcode generated just states the refund amount (5 digits) that you’ll get at the register. Just stick the barcode under something like a six pack and it’ll scan even without the cashier seeing it.

Germany’s Chaos Computer Club has announced the theme for their annual Chaos Communication Congress: “Nothing to hide“. Like last year’s “Full steam ahead!“, it’s open to many interpretations. People striking down privacy laws often say citizens shouldn’t mind since they have “Nothing to hide”. The phrase is also connected to the inability to hide data, as the CCC demonstrated this year by publishing the German Home Secretary’s fingerprint. On a more positive side, “Nothing to hide” is also about the free exchange of information that happens at hacker conventions. The Congress is in its 25th year and promises to be as good as ever. At last year’s 24C3, we saw great talks like [Drew Endy]’s biohacking talk and the original MiFare crypto presentation. 25C3 will be held in Berlin December 27th to 30th. The wiki is already up and they’ve published a call for participation, if you’re interested.

The random number generator ended up being only 16-bit. It generates this number based on how long since the card has been powered up. They controlled the reader (an OpenPCD) which lets them generate the same “random” seed number over and over again. This was actually happening on accident before they discovered the flaw.

If you haul heavy loads your wheel bearings will wear out more quickly. An often forgotten wheel bearing is on trailers. So don’t forget to have those wheel bearings checked along with your vehicle. If your vehicle is consistently weighed down, you will need to replace your wheel bearings more frequently.

[Drew Endy]’s Programming DNA talk was by far the most interesting talk we saw at Chaos Communication Congress. No, DNA doesn’t have much to do with computers, but he points out that hacking principles can be applied just the same. Right now engineers are reversing genetic code and compiling building blocks for creating completely arbitrary organisms. This talk was designed to bootstrap the hacking community so that we can start using and contributing standard biological parts to an open source collection of genetic functions.
A wheel bearing is a set of steel balls connected by a metal ring. It sits tightly in the middle of the hub. Wheel bearings require grease to lubricate them, with a seal keeping the grease in the bearing. The seal also acts as a barrier against dirt and debris that can cause corrosion. The seal is essential to the durability of the wheel bearing.

You’ve probably never thought about how your tires work. They sit under your car and help get you where you need to go. But, there are many components to a car wheel and one of the extremely important ones is the wheel bearing. Wheel bearing failure can cause serious problems for you and your car so it is beneficial to know what a wheel bearing is and what pitfalls to avoid in order to prevent wheel bearing failure.
If you recently had your wheel bearings installed or repaired and you are still experiencing issues, take it back to your mechanic immediately. In order to avoid this inconvenient and unsafe situation, it is important to find a reliable mechanic that you trust to do a good job in the first place.
Wheel bearings allow the wheel to spin rapidly without too much friction. They also carry the weight of the car, which can be over 4,000 pounds.
You should definitely watch the video to get a good idea of where biohacking is at today. You can find a higher quality version of the video in the archives.

The most common and easiest sign of wheel bearing failure is the noise it will make. If you hear a growling, rumbling, humming, screeching, or squealing noise that gets louder or goes away as you change driving speed, you should take it to your mechanic to have your wheel bearings checked.

Another highlight for us at CCC was [Karsten Nohl] and [Henryk Plötz] presenting how they reversed Philips crypto-1 “classic” Mifare RFID chips which are used in car keys, among other things. They analyzed both the silicon and the actual handshaking over RF. Looking at the silicon they found about 10K gates. Analyzing with Matlab turned up 70 unique functions. Then they started looking “crypto-like” parts: long strings of flip-flops used for registers, XORs, things near the edge that were heavily interconnected. Only 10% of the gates ended up being crypto. They now know the crypto algorithm based on this analysis and will be releasing later in the year.
If your wheel bearing fails, it can cause the wheel to stop while you are driving or possibly even to fall off. At the very least, before a wheel falls off, a failed wheel bearing can/will cause significant damage to your vehicle, so it’s very important to keep an eye on these and keep them maintained. If you suspect a wheel bearing failure do not continue to drive on it. Take it to your mechanic immediately. And don’t hesitate to consult your mechanic if you have any questions about your wheel bearings at all. They are happy to help and want to keep you safe.
Unfortunately, another common cause of wheel bearing failure is improper installation. This can occur if a mechanic is negligent or doesn’t install the wheel bearings according to manufacturer guidelines. They may also use poor quality wheel bearings. Using a low quality wheel bearing will cause premature wear and possible failure because they will mix hard and soft metal, causing spalling to occur. Spalling is when the bearing wears down enough to the soft metal underneath, which will peel off in flakes.

You should be getting your tires balanced on a regular basis for many reasons. One of those reasons is to protect your wheel bearings. If your tires are not balanced you will be putting uneven strain on certain tires, causing those wheel bearings to work much harder, and wear out faster.
A good wheel bearing made of high quality steel should last 100,000 miles or more, if you take care of it and your car in general.

Almost every security conference we’ve attended in the last year has uploaded videos from their speaker tracks. Explore the archives below, and you’re bound to find an interesting talk.

[nico] just received his credentials for an upcoming conference. On each badge, there’s a 2D barcode with the participant’s bio and contact info. These are meant to be scanned by vendors for future contact. [nico] isn’t so interested in that and plans on updating his personal info by generating a new barcode. To this end, he’s collected a number of links to help out barcode hackers. He used the SWIPE toolkit to identify the format and decode (it has an online component too). There are also several online encoders you can use, like this one from [Terry Burton]. If you’re wondering what sort of shenanigans you can get into faking barcodes, check out [fx]’s presentation from 24C3.
If you consistently drive on bumpy roads, dirt roads, salty roads, or roads with potholes this will take a toll on your wheel bearings. The wheel bearings are carrying your entire car while ensuring your wheels continue to spin as needed. We put a lot of strain on them just from daily driving. When bumps occur we are putting extra strain on them.

While the seal is there to act as a barrier against dirt, debris, and water, it cannot withstand large quantities of water putting pressure on it. Driving in water that is hub deep or higher may allow water into the wheel bearing. This will contaminate the lubricant, causing potential wheel bearing failure. This is why the passenger side wheel bearings tend to wear out more quickly, since they spend more time in standing water in the gutter, when parked. If you have driven through flooded roads or puddles, you should have your wheel bearings checked immediately.
