Congratulations to our winner, Earl.
For years, analysts predicted that all of our devices — PCs, laptops, DVD players, mobile phones — would merge into one all-purpose device that would handle everything we do digitally. Surprisingly we are seeing more and more that people are actually travelling with up to three devices — a phone, a tablet and a laptop. All three perform similar functions but provide vastly different experiences.
We’ve discussed the proper way to secure all your devices. So now we have a question for you: For mobile connections, do you use a tablet a mobile phone or both?
Just read the rules and post your answer in the comments below.

Whistleblowers have changed the world and there’s still a lot of hidden secrets that the public really should know about. High-profile leakers like Snowden, Manning and Assange are known globally, and are paying a high price for their courage. But only a few are dedicated enough to blow the whistle in public - most leakers want to carry on with their normal lives and remain anonymous. Snowden did no doubt show the way for others, and there are already several who have tried to leak and remain anonymous. That’s not easy and the stakes are high! Which is underlined by the recent news about the feds discovering one leaker. But is it even possible to leak anonymously in this word that in many ways is worse than Orwell’s fictive surveillance nightmare? Let’s list some advice for the case you would like to leak by phone to a journalist. I guess not many of you readers will ever be in a situation where you need this. But read on, this is highly interesting anyway and tells a lot about how our digital word works. Ok, let’s assume the worst case. The secrets you want to leak affects US national security, which means that your enemy is powerful and can use top surveillance against you. Let’s also assume it’s info you have authorized access to. And that you want to talk on the phone to a journalist. Here’s some basic rules and hints that may prevent you from ending up behind bars. First you need to assess how many persons have access to the data. They will all be on a list of suspects, together with you. The shorter the list, the bigger the risk for you. Your mobile phone is a tracking device. The cell phone network knows what base station you are connected to at any time. Other services can record and store even GPS-accurate position data. All this is accessible to the agents and you must make sure it doesn’t reveal you. Needless to say, your own phone does not participate in this project. You need to find out who you should leak to. Never do this research from your own computer because your search history can reveal you. It leaves traces both in your computer and in your user profile at Google (unless you know what you are doing and use privacy tools properly). Do this research from a public computer. Make sure you have never logged in to any personal account from this computer. You need a “burner phone” to do the leaking. This is a phone that can’t be connected to your identity in any way. Here’s some rules for how to use it: It is always switched off with the battery removed when not in use. Just using the power button does not cut power from all parts of the device. It is never switched on in or close to your home. The agents can easily find out what base station it was connected to and turning it on near home can make you more suspected than others. It is never switched on in or close to your vehicle. Base station records for the phone may correlate with traffic cameras storing your registration plate. This is especially important if you have a modern car with a built-in data connection for service monitoring etc. Never user the burner for any other contacts. Even a single call to your spouse creates a record that ties you to the phone. Needless to say, never store any other info in the phone than what you need for this project. You always leave your own phone at home when going out to use the burner phone. Otherwise the agents can see that your own phone “happen” to be in the same base station when the burner is used. Leave your own phone turned ON at home when you go out with the burner. Otherwise you create a recognizable pattern where your own phone turns off and the burner turns on, and vice versa, in a synchronized manner. Leave any other wireless devices at home. Tablets, wireless mobile payment devices, anything else with a radio transmitter. Using a voice changer is necessary especially if the list of suspects is short. Assume that your calls can be recorded and your own voice checked against the recording. Get the burner phone. Scout for a dealer with old-looking or insufficient security cameras located not too close to your home. Remember that the agents may locate the shop where the burner phone was sold, get the security camera recording and compare against the list of suspects. Even better, ask someone else to buy the phone for you. Choose a cheap non-smart prepaid phone with removable battery. Pay cash and make sure you don’t reveal your identity to the seller in any way. Safely destroy any receipts and other paperwork related to the purchase. Think about where to store physical items that can tie you to the leak. Such items are the burner phone and related documents or data media. This is especially important if the list of suspects is short. Storing such items at home, at your workplace or in your vehicle will reveal you if the agents perform a search. Try to find some other place that is safe and can’t be tied to you. Now you are ready to contact the journalist. Be very rigid with the rules for how to use the burner phone. There are also some additional rules for this situation: Dress discreetly to avoid sticking out in surveillance camera footage. Be far enough from home when making the call. Turn the burner on, make the call and turn it off again right away. Avoid public places with surveillance cameras when the burner is on. Do not use your credit card during this trip. Pay cash for everything. Any other personal payment instruments, like public transportation payment cards, is a big no-no as well. You have to assume that journalists dealing with leaks are being watched constantly. Assume that the hunt is on as soon as you have made the first contact. Try to wrap up the project as quickly as possible and minimize the number of times you turn on the burner phone. When you are done, dispose all items related to the leak in a secure way. The trash can of your own house is NOT secure. Dump the phone in the river or put it in a public trash sack far enough from home. The truly paranoid leaker will break the phone with gloves on. The outer shell can contain fingerprints or traces of your DNA and the electronics the traceable phone ID. It’s good to make sure they end up in different places. Huh! That’s a lot to remember. Imagine, all this just for maintaining privacy when making a phone call! But you really need to do it like this if the big boys are after you and you still want to continue as a free citizen. I hope you never need to go through all this, and also that you do it right if you have to. Disclaimer. This text is mainly intended as a demonstration of how intrusive the surveillance society is today. We provide no guarantee that this will be enough to keep you out of jail. If you really plan to become a whistle blower, research the topic thoroughly and get familiar with other sources as well (but remember what I wrote about researching from your own computer). Safe whistle blowing, Micke
The recent statements from FBI director James Comey is yet another example of the authorities’ opportunistic approach to surveillance. He dislikes the fact that mobile operating systems from Google and Apple now come with strong encryption for data stored on the device. This security feature is naturally essential when you lose your device or if you are a potential espionage target. But the authorities do not like it as it makes investigations harder. What he said was basically that there should be a method for authorities to access data in mobile devices with a proper warrant. This would be needed to effectively fight crime. Going on to list some hated crime types, murder, child abuse, terrorism and so on. And yes, this might at first sound OK. Until you start thinking about it. Let’s translate Comey’s statement into ordinary non-obfuscated English. This is what he really said: “I, James Comey, director of FBI, want every person world-wide to carry a tracking device at all times. This device shall collect the owner’s electronic communications and be able to open cloud services where data is stored. The content of these tracking devices shall on request be made available to the US authorities. We don’t care if this weakens your security, and you shouldn’t care because our goals are more important than your privacy.” Yes, that’s what we are talking about here. The “tracking devices” are of course our mobile phones and other digital gadgets. Our digital lives are already accurate mirrors of our actual lives. Our gadgets do not only contain actual data, they are also a gate to the cloud services because they store passwords. Granting FBI access to mobile devices does not only reveal data on the device. It also opens up all the user’s cloud services, regardless of if they are within US jurisdiction or not. In short. Comey want to put a black box in the pocket of every citizen world-wide. Black boxes that record flight data and communications are justified in cockpits, not in ordinary peoples’ private lives. But wait. What if they really could solve crimes this way? Yes, there would probably be a handful of cases where data gathered this way is crucial. At least enough to make fancy PR and publically show how important it is for the authorities to have access to private data. But even proposing weakening the security of commonly and globally used operating systems is a sign of gross negligence against peoples’ right to security and privacy. The risk is magnitudes bigger than the upside. Comey was diffuse when talking about examples of cases solved using device data. But the history is full of cases solved *without* data from smart devices. Well, just a decade ago we didn’t even have this kind of tracking devices. And the police did succeed in catching murderers and other criminals despite that. You can also today select to not use a smartphone, and thus drop the FBI-tracker. That is your right and you do not break any laws by doing so. Many security-aware criminals are probably operating this way, and many more would if Comey gets what he wants. So it’s very obvious that the FBI must have capability to investigate crime even without turning every phone into a black box. Comey’s proposal is just purely opportunistic, he wants this data because it exists. Not because he really needs it. Safe surfing, Micke
Yet another high-profile vulnerability in the headlines, Shellshock. This one could be a big issue. The crap could really hit the fan big time if someone creates a worm that infects servers, and that is possible. But the situation seems to be brighter for us ordinary users. The affected component is the Unix/Linux command shell Bash, which is only used by nerdy admins. It is present in Macs as well, but they seem to be unaffected. Linux-based Android does not use Bash and Windows is a totally different world. So we ordinary users can relax and forget about this one. We are not affected. Right? WRONG! Where is your cloud content stored? What kind of software is used to protect your login and password, credit card number, your mail correspondence, your social media updates and all other personal info you store in web-based systems? Exactly. A significant part of that may be on systems that are vulnerable to Shellshock, and that makes you vulnerable. The best protection against vulnerabilities on your own devices is to make sure the automatic update services are enabled and working. That is like outsourcing the worries to professionals, they will create and distribute fixes when vulnerabilities are found. But what about the servers? You have no way to affect how they are managed, and you don’t even know if the services you use are affected. Is there anything you can do? Yes, but only indirectly. This issue is an excellent reminder of some very basic security principles. We have repeated them over and over, but they deserve to be repeated once again now. You can’t control how your web service providers manage their servers, but you can choose which providers you trust. Prefer services that are managed professionally. Remember that you always can, and should, demand more from services you pay for. Never reuse your password on different services. This will not prevent intrusions, but it will limit the damage when someone breaks into the system. You may still be hurt by a Shellshock-based intrusion even if you do this, but the risk should be small and the damage limited. Anyway, you know you have done your part, and its bad luck if an incident hurts you despite that. Safe surfing, Micke PS. The best way to evaluate a service provider’s security practices is to see how they deal with security incidents. It tells a lot about their attitude, which is crucial in all security work. An incident is bad, but a swift, accurate and open response is very good. Addition on September 30th. Contrary to what's stated above, Mac computers seem to be affected and Apple has released a patch. It's of course important to keep your device patched, but this does not really affect the main point of this article. Your cloud content is valuable and part of that may be on vulnerable servers.
