The world’s GPS system is vulnerable to hackers or terrorists who could use it to hijack ships -- even commercial airliners, according to a frightening new study that exposes a huge potential hole in national security.

I wonder if there is anyone out there to take over from this guy in showcasing the weaknesses of modern technology?

Won't be long before it leaks out..

Car Key Immobilisers hacked

Ain't technology grand.

Fire risk

With the amount of electronics on modern planes these days, why no fire detection in that area?

Fire risk

With the amount of electronics on modern planes these days, why no fire detection in that area?

Further than that, for the very low cost and weight of temperature sensors, why not multiple strings of temperature sensors the full length of the aircraft innards to monitor and detect any 'anomaly' long before anything approaching the danger of an onboard fire?...


There is a long know problem of vibration chafing and damage from routine maintenance to aircraft cabling... I wonder if there is now a very ugly reliability problem for the cabling from the ever greater reliance upon all-electric systems and the ever greater design pressures to reduce weight...

Cables often go through hard to install and hard to inspect areas...

A rather mixed bag of ugly, bad, and good:


Australia threatens Adobe, Apple, with geo-blocking ban

... Those recommendations suggest Australia:

Remove restrictions on parallel/gray market imports;
Changes its Copyright Act “to clarify and secure consumers’ rights to circumvent technological protection measures that control geographic market segmentation”;
Create a “right of resale” for digital goods
Educate Australian consumers and businesses on how to circumvent geoblocking and what it will mean for their rights;
A ban on geo-blocking “as an option of last resort, should persistent market failure exist in spite of the changes … recommended in this report.”

The second recommendation is tantamount to legitimising VPNs for avoiding [restrictive] copyright controls [(restrictions)]...




Western spooks banned Lenovo PCs after finding back doors

Chinese PC giant Lenovo has been banned from supplying kit for the top secret networks of western intelligence agencies after security concerns emerged when backdoor vulnerabilities were detected...

... Serious backdoor vulnerabilities in hardware and firmware were apparently discovered during the tests which could allow attackers to remotely access devices without the knowledge of the owner. ...




New in Android 4.3: At last we get a grip on privacy-invading crApps

... There may also be a backlash from developers who don't want their advertising ... denied network access...

I just find it odd that people are so alarmed at these secret back doors in software. I can still remember the "Easter eggs" in most Microsoft programs years ago, that activated if you used a certain combination of key presses. My favourite was the green gremlin of Lotus 123 that got bashed in Excel. Programmers have always left secret back doors.

Gary, I co-admined a 1000 user building in central London on Novell Netware in the mid 1990's. Day to day we used the Supervisor accounts, when necessary we used the Administrator or God account. But we also had a back door account in case the Admin A/C got screwed up. Back doors are secret openings into the control of systems, that are not made public.

Right, just keep the password secret. Now if your shop created a second root account, that would be a secure way to do it as you can control the password. If you need physical access that can be secure as well.

The item here was a computer the manufacturer put a backdoor in, same a a default account. Problem is if the hardware has a backdoor account, everyone who has the hardware now knows about it and has the password, never mind the tech manual posted to a website like wikileaks. No secret at all. Just the same as leaving the default username / password on your router. And they weren't telling anyone it was there or giving an option to change the username password or disable it. Essentially they are giving root access to anyone and everyone!

Now are you beginning to understand the implications of a hardware backdoor?

When you say root access, that to me means Unix parlance. In Netware you can only have one God account. What we had was a Demigod account with full Admin equivalence that would allow us to get into the server if the Admin account got screwed up. The password was in a sealed envelope kept in a fire safe. We are of course talking here of software backdoors.

Hardware backdoors are another matter entirely, and I assume hard coded into chips like EPROMS. As you say, once that backdoor becomes known about then the device is compromised. It is good to have emergency access to anything when dire things happen, from buildings to computers, but that has to be balanced against security on a day to day basis. Outfits like Wikileaks should be closed down and put out of business as a matter of urgency.

When the hardware itself is hacked, NO security, no matter how strong, is totally useless so your password/s in sealed envelopes might as well be used to light up a ciggie.

As for sites like Wikileaks, without those most users will be ignorant that their systems are wide open.

Indeed so.

Note how most 'hardware' in recent years often includes or relies upon a 'firmware' component. If there is any internet or any other supplier access possible, that could be reprogrammed to anything at any time. No user intervention needed. Such as mobile phones highly vulnerably have that very feature ever present...

There's also been an example of the firmware of a PC/server network card being subverted by not-so-random data packets...

Currently, there is a CERT security alert about servers motherboard hardware controls using IPMI:

... Original release date: July 26, 2013 | Last revised: July 30, 2013
Systems Affected

Any system connected to the internet running the Intelligent Platform Management Interface (IPMI) may be affected. IPMI is resident on many server platforms, and provides low-level access to a system that can override operating system controls.

Overview

Attackers can easily identify and access systems that run IPMI and are connected to the Internet. It is important to restrict IPMI access to specific management IP addresses within an organization and preferably separated into a separate LAN segment. ...


(Geee... Is that why I run segregated multiple LANs dependent on use/traffic?...)


Perhaps you should watch The Net (1995)... (Thanks whoever that poster was earlier.)

[Normal service off]

Oooh do be careful Sirius and Martin, the hackers are out there 24/7 just waiting to get you. Don't use your mobile phone, don't use your computer, close your bank account, give all your assets to charity. Stay indoors, don't go out, keep looking over your shoulder every 30 seconds. You know it makes sense. Never forget that they are out there .....



[Normal service on]

We apologise for the recent loss of normal service, this was due to a glitch in some Seti users.
