Some essential additions to our Internet glossary

1390397_79061953_330Times are changing and we have to learn new things all the time. People interested in privacy on the Internet have been faced with a flood of new acronyms and terms lately. Here comes a brief list of terminology that has remained fairly unknown for a long time, but suddenly become very central to how our cyber society is developing. Keep these in mind if you want to be privacy-savvy.

Echelon
The best know signal intelligence system of the cold war era. Operated by the NSA and capable to store and analyze both data and telephone traffic globally. Today a legacy system.

FISA, Foreign Intelligence Surveillance Act
A US law that, together with other related laws and amendments, controls usage of non-US citizens’ communications for the benefit of US interests. Controls is however a misleading word as it pretty much boils down to carte blanche to spy on foreigners. This is of paramount importance for the whole Internet as most of the cloud services are run by American companies, and most users are foreigners.

FISC, FISA-Court, United States Foreign Intelligence Surveillance Court
A secret US court that is supposed to review and approve data gathering efforts under the FISA and related laws. Evil tongues call it a rubber stamp, but it has actually denied 11 requests out of a total of 33 949 during 1979-2012. (Some of those 11 were approved after modification.)

Gag Order
A court order to shut up about something.

GCHQ, Government Communications Headquarters
UK’s own NSA. Responsible for gathering info from Internet traffic for the needs of the UK government and military.

Lavabit
A former encrypted mail service run by Ladar Levinson. Became iconic in the fight for Internet privacy when closed down in August 2013. According to Ladar: “I have been forced to make a difficult decision: to become complicit in crimes against the American people or walk away from nearly ten years of hard work by shutting down Lavabit.” This smells NSL (see below) to high heaven.

NSA, National Security Agency
USA’s main signals intelligence agency. Operates globally to intercept and decode information. Recent reports indicate that NSA’s strategy largely seems to be to store as much information as possibly for further use, rather than picking targets and eavesdropping selectively. NSA is also a leader in cryptography and cryptanalysis, and is believed to have more supercomputer capacity than anyone else on this planet.

NSL, National security letter
An order from a US agency to hand over information or implement information gathering systems. These letters come with strict gag orders that even prevents the subject from revealing the existence of a NSL or seeking legal advice about it. Their legal status is controversial because of the broad gag orders that are in conflict with the 1st amendment. Anyone should keep the NSLs in mind when listening to top executives of Google, Facebook, Apple etc. who denies that NSA can tap into their systems.

PRISM
Currently the best known of all the data gathering programs run by NSA. PRISM is apparently a database application that stores data from many sources.

SIGINT, Signals intelligence
Operations aiming to gather information by eavesdropping on communications and other signals or stored data. Involves the art of decoding or decrypting messages as well as gathering information by analyzing traffic patterns.

Tempora
A system run by UK’s GCHQ that collects data in real time from internet and telephone communications.

Utah data center
A data center located in Bluffdale, Utah and operated by the NSA. The center is about to be finalized and believed to provide 3 – 12 Exabyte of storage data right now, more in the future as storage technology evolves. It has been said that five Exabyte is equivalent to all words ever spoken by humans since the dawn of time. This is outdated, but still interesting when trying to imagine how much an Exabyte really is. So what exactly is NSA going to do with all this storage?

XKeyscore
A NSA system that gives analysts powerful tools to query for information about identified targets or suspicious patterns in larger datasets.

Whistleblower
A person who makes crimes or other unethical activities known to a larger public, often by violating agreements or the law. A significant portion of what we know about SIGINT on the Internet has been revealed by whistleblowers.

This list of secret NSA programs and codenames is far from complete. Security guru Bruce Schneier puts it very well in a TED interview together with our Mikko Hyppönen.

Bruce Schneier: “First, be careful with names. PRISM is a specific NSA database, just a part of the overall NSA surveillance effort. The agency has been playing all sorts of games with names, dividing their efforts up and using many different code names in an attempt to disguise what they’re doing. It allows them to deny that a specific program is doing something, while conveniently omitting the fact that another program is doing the thing and the two programs are talking to each other. So I am less interested in what is in the specific PRISM database, and more what the NSA is doing overall with domestic surveillance.”

Very well said! Here you can find a more comprehensive list of NSA programs and codenames.

Windows 10, Windows privacy and security, Windows 10 new features

5 things you need to know to feel secure on Windows 10

New versions of windows used to be like an international holiday. PC users around the world celebrated by sharing what they liked -- much of Windows 7 --- and hated -- all of Windows 8 and Vista -- about the latest version of the world's most popular operating system. In this way, Windows 10 is the end of an era. This is the "final version" of the OS. After you step up to this version, there will be continual updates but no new version to upgrade to. It's the birth of "Windows as a service," according to Verge. So if you're taking free upgrade to the new version, here are 5 things you need to know as you get used to the Windows that could be with you for the rest of your life. 1.Our Chief Research Office Mikko Hypponen noted Windows 10 still hides double extensions by default. “Consider a file named doubleclick.pdf.bat. If ‘hide extensions’ is enabled, then this will be shown in File Explorer as ‘doubleclick.pdf’. You, the user, might go ahead and double-click on it, because it’s just a PDF, right?” F-Secure Security Advisor Tom Gaffney told Infosecurity Magazine. “In truth, it’s a batch file, and whatever commands it contains will run when you double-click on it.” Keep this in mind when you do -- or DON'T -- click on unknown files. 2. You could end up sharing your Wi-Fi connection with all your contacts. There's some debate about whether or not Windows 10's Wi-Fi Sense shares your Wi-Fi connection with social media contacts by default, as Windows Phone has for a while now. ZDNet's Ed Bott says no, noting that "you have to very consciously enable sharing for a network. It's not something you'll do by accident." Security expert Brian Krebs is more skeptical, given how we're "conditioned to click 'yes' to these prompts." "In theory, someone who wanted access to your small biz network could befriend an employee or two, and drive into the office car park to be in range, and then gain access to the wireless network," The Register's Simon Rockman wrote. "Some basic protections, specifically ones that safeguard against people sharing their passwords, should prevent this." Gaffney notes that Wi-Fi Sense is “open to accidental and deliberate misuse.” So what to do? Krebs recommends the following: Prior to upgrade to Windows 10, change your Wi-Fi network name/SSID to something that includes the terms “_nomap_optout”. [This is Windows opt-out for Wi-Fi Sense]. After the upgrade is complete, change the privacy settings in Windows to disable Wi-Fi Sense sharing. 3. There are some privacy issues you should know about. Basically "whatever happens, Microsoft knows what you're doing," The Next Web's Mic Wright noted. Microsoft, according to its terms and conditions, can gather data “from you and your devices, including for example ‘app use data for apps that run on Windows’ and ‘data about the networks you connect to.'” And they can also disclose it to third parties as they feel like it. You should check your privacy settings and you can stop advertisers from know exactly who you are. Want a deep dive into the privacy issues? Visit Extreme Tech. 4. The new Action Center could be useful but it could get annoying. This notification center makes Windows feel more like an iPhone -- because isn't the point of everything digital to eventually merge into the same thing? BGR's Zach Epstein wrote "one location for all of your notifications is a welcome change." But it can get overwhelming. "In Windows 10, you can adjust notifications settings by clicking the notifications icon in the system tray," he wrote. "The click All settings, followed by System and then Notifications & actions." 5. Yes, F-Secure SAFE, Internet Security and Anti-Virus are all Windows 10 ready. [Image by Brett Morrison | Flickr]

Android’s Stagefright bug – phone vendors taken with their pants down

You have all heard the classic mantra of computer security: use common sense, patch your system and install antivirus. That is still excellent advice, but the world is changing. We used to repeat that mantra over and over to the end users. Now we are entering a new era where we have to stress the importance of updates to manufacturers. We did recently write about how Chrysler reacted fairly quickly to stop Jeeps from being controlled remotely. They made a new firmware version for the vehicles, but didn’t have a good channel to distribute the update. Stagefright on Android demonstrates a similar problem, but potentially far more widespread. Let’s first take a look at Stagefright. What is it really? Stagefright is the name of a module deep inside the Android system. This module is responsible for interpreting video files and playing them on the device. The Stagefright bug is a vulnerability that allows and attacker to take over the system with specially crafted video content. Stagefright is used to automatically create previews of content received through many channels. This is what makes the Stagefright bug really bad. Anyone who can send you a message containing video can potentially break into your Android device without any actions from you. You can use common sense and not open fishy mail attachments, but that doesn’t work here. Stagefright takes a look at inbound content automatically in many cases so common sense won't help. Even worse. There’s not much we can do about it, except wait for a patch from the operator or phone vendor. And many users will be waiting in vain. This is because of how the Android system is developed and licensed. Google is maintaining the core Linux-based system and releasing it under an open license. Phone vendors are using Android, but often not as it comes straight from Google. They try to differentiate and modifies Android to their liking. Google reacted quickly and made a fix for the Stagefright bug. This fix will be distributed to their own Nexus-smartphones soon. But it may not be that simple for the other vendors. They need to verify that the patch is compatible with their customizations, and releasing it to their customers may be a lengthy process. If they even want to patch handsets. Some vendors seems to see products in the cheap smartphone segment as disposable goods. They are not supposed to be long-lived and post-sale maintenance is just a cost. Providing updates and patches would just postpone replacement of the phone, and that’s not in the vendor’s interest. This attitude explains why several Android vendors have very poor processes and systems for sending out updates. Many phones will never be patched. Let’s put this into perspective. Android is the most widespread operating system on this planet. 48 % of the devices shipped in 2014 were Androids (Gartner). And that includes both phones, tablets, laptops and desktop computers. There’s over 1 billion active Android devices (Google’s device activation data). Most of them are vulnerable to Stagefright and many of them will never receive a patch. This is big! Let’s however keep in mind that there is no widespread malware utilizing this vulnerability at the time of writing. But all the ingredients needed to make a massive and harmful worm outbreak are there. Also remember that the bug has existed in Android for over five years, but not been publically known until now. It is perfectly possible that intelligence agencies are utilizing it silently for their own purposes. But can we do anything to protect us? That’s the hard question. This is not intended to be a comprehensive guide, but it is however possible to give some simple advice. You can stop worrying if you have a really old device with an Android version lower than 2.2. It’s not vulnerable. Google Nexus devices will be patched soon. A patch has also been released for devices with the CyanogenMod system. The privacy-optimized BlackPhone is naturally a fast-mover in cases like this. Other devices? It’s probably best to just google for “Stagefright” and the model or vendor name of your device. Look for two things. Information about if and when your device will receive an update and for instructions about how to tweak settings to mitigate the threat. Here’s an example.   Safe surfing, Micke Image by Rob Bulmahn under CC BY 2.0

The Devil’s in… the browser

This is the fourth in a series of posts about Cyber Defense that happened to real people in real life, costing very real money. It was only just past 1 pm, but Magda was already exhausted. She had recently fired her assistant, so she was now having to personally handle all of the work at her law office. With the aching pain in her head and monstrous hunger mounting in her stomach, Magda thought it was time for a break. She sat at her desk with a salad she had bought earlier that morning and decided she’d watch a short online video her friends had recently told her about. She typed the title in the browser and clicked on a link that took her to the site. A message popped up that the recording couldn’t be played because of a missing plugin. Magda didn’t have much of an idea what the “plugin” was, which wasn’t surprising considering that her computer knowledge was basic at best – she knew enough to use one at work, but that was pretty much all. It was the recently sacked assistant, supported by an outsourced IT firm, who took care of all things related to computers and software. A post-it stuck to Magda’s desk had been unsuccessfully begging her to install an antivirus program. “What was this about?”, Magda tried to remember. At moments like this, she regretted letting the girl go. After some time, she recalled that her assistant had mentioned something about a monthly subscription plan for some antivirus software to protect the computers, tablets and mobile phones. This solution, flexible and affordable for small businesses like Magda’s firm, had also been also recommended by the outsourced IT provider. Despite a nagging feeling that something wasn’t right, she clicked “install”. After a few seconds, the video actually played. Magda was very proud of herself: she had made the plugin thing work! A few days later, she logged into her internet banking system to pay her firm’s bills. As she looked at the balance of the account, she couldn’t believe her eyes. The money was gone! The transaction history showed transfers to accounts that were completely unknown to her. She couldn’t understand how somebody was able to break in and steal her money. The bank login page was encrypted, and besides that, she was the only person who knew the login credentials... At the bank she learnt that they had recorded a user login and transfer orders. Everything had been according to protocol, so the bank had no reason to be suspicious. The bank’s security manager suggested to Magda that she may have been the victim of a hacker’s attack. The IT firm confirmed this suspicion after inspecting Magda’s computer. Experts discovered that the plugin Magda had downloaded to watch the video online was actually malware that stole the login credentials of email accounts, social networking sites and online banking services. Magda immediately changed her passwords and decided to secure them better. She finally had good antivirus software installed, which is now protecting all of the data stored on her computer. She recalled that her bank had long been advising to do that, but she had disregarded their advice. If only she hadn’t... Her omission cost her a lot of money. She was happy, though, that money was all she lost. She didn’t even want to imagine what might have happened if any of her case or clients information had been compromised. That would have been the end of her legal career. "If you have to use dangerous plugins like Java to do banking, you can enable those in one browser and use it only for the banking stuff," F-Secure Director of Security Response Antti Tikkanen explains.​ To get an inside look at business security, be sure to follow our Business Insider blog.
