Times 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.
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.)
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.
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.
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.
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?
A NSA system that gives analysts powerful tools to query for information about identified targets or suspicious patterns in larger datasets.
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.
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.
Bitcoin has not only changed the economics of cybercrime by providing crooks with an encrypted, nearly anonymous payment system autonomous from any central bank. It's also changed researchers' ability to track how much money criminals are making. "Bitcoin is based on Blockchain, and Blockchain is a public ledger of transactions. So all Bitcoin transactions are public," explains Mikko Hyppönen, F-Secure's Chief Research Officer. "Now, you don’t know who is who. But we can see money moving around, and we can see the amounts." Every victim of Ransomware -- malware that encrypts files and demands a payment for their release -- is given a unique wallet to transfer money into. Once paid, some ransomware gangs move the bitcoins to a central wallet. "We've been monitoring some of those wallets," Mikko says. "And we see Bitcoins worth millions and millions. We see a lot of money." Watching crooks rake in so much money, tax-free, got him thinking: "I began to wonder if there are in fact cybercrime unicorns." A cybercrime unicorn? (View this as a PDF) A tech unicorn is a privately held tech company valued at more than a billion dollars. Think Uber, AirBNB or Spotify -- only without the investors, the overhead and oversight. (Though the scam is so profitable that some gangs actually have customer service operations that could rival a small startup.) "Can we use this comparison model to cybercrime gangs?" Mikko asks. "We probably can’t." It's simply too hard to cash out. Investors in Uber have people literally begging to buy their stakes in the company. Ransomware gangs, however, have to continually imagine ways to turn their Bitcoin into currency. "They buy prepaid cards and then they sell these cards on Ebay and Craigslist," he says. "A lot of those gangs also use online casinos to launder the money." But even that's not so easy, even if the goal is to sit down at a online table and attempt to lose all your money to another member of your gang. "If you lose large amounts of money you will get banned. So the gangs started using bots that played realistically and still lose – but not as obviously." Law enforcement is well aware of extremely alluring economics of this threat. In 2015, the FBI’s Internet Crime Complaint Center received "2,453 complaints identified as Ransomware with losses of over $1.6 million." In 2016, hardly has a month gone by without a high-profile case like Hollywood Presbyterian Medical Center paying 40 Bitcoin, about $17,000 USD at the time, to recover its files. And these are just the cases we're hearing about. The scam is so effective that it seemed that the FBI was recommending that victims actually pay the ransom. But it turned out their answer was actually more nuanced. "The official answer is the FBI does not advise on whether or not people should pay," Sean Sullivan, F-Secure Security Advisor, writes. "But if victims haven’t taken precautions… then paying is the only remaining alternative to recover files." What sort of precautions? For Mikko, the answer obvious. "Backups. If you get hit you restore yesterday’s backup and carry on working. It could be more cumbersome if it’s not just one workstation, if your whole network gets hit. But of course you should always have good, up to date, offline backups. And 'offline' is the key!" What's also obvious is that too few people are prepared when Ransomware hits. Barring any disruptions to the Bitcoin market, F-Secure Labs predicts this threat will likely persist, with even more targeted efforts designed to elicit even greater sums. If you end up in an unfortunate situation when your files are held hostage, remember that you're dealing with someone who thinks of cybercrime as a business. So you can always try to negotiate. What else do you have to lose?
This is really an old problem, but it’s in the headlines again. Pokémon Go is yet another example of a “free” game with a business model based on in-app purchases. These games are also known as F2P, standing for free-to-play. You can start playing, and get hooked, for free. But soon you run into a situation where you can’t proceed without buying virtual stuff in the game. The stuff you buy is virtual but the payment is very real money. This is no doubt a profitable model. Pokémon Go went straight to the top and for example Finland-based Supercell, maker of Clash of Clans, has constantly reported nice profits. This can naturally cause trouble for addicted adults, but the real problems arise when kids get hooked. There are numerous public stories about kids making purchases for hundreds or even thousands of Euros, often without even understanding how much they have spent. And the sinister part is that this can go on for a while until you get the credit card bill, and it’s too late. Your chances to get a refund are somewhere between slim and none. But how can this happen? Let’s take a look at the most common scenarios. Your kid has set up the new device and created the needed account with Apple or Google. Everything is fine until he or she needs an app that isn’t free. You enter your credit card on the kid’s device and make the purchase, but you don’t pay any attention to the security settings. This may give your kid carte blanche to buy anything he or she likes, and you pay the bill. You have entered your credit card but set up the kid’s store account so that a password only you know is required for every purchase. But there are some convenient settings that allow purchases without a password within a limited time window after the password has been entered. Kids learn very quickly to utilize this opportunity. Let’s assume the same setup as in the previous point, but with the correct security settings. Now the password is needed for every purchase. But the store account is still owned by the kid and the password can be reset. The password reset link will be sent to the kid’s mail or phone number. It’s carte blanche again with the new password. Ok, you create an account you own for the kids phone. It’s tied to your mail and phone number, so the password reset trick shouldn’t work anymore. You put down your phone and head for the toilet. Your kid has been waiting for the opportunity and initiates the password reset request. Your phone is there on the table wide open, with the reset link in the mail. You can figure out the rest yourself. And of course the simple alternative. You think the store password on your kid’s device is secret. But in reality it is either too easy to guess or someone has been looking over your shoulder. So there’s many things that can go wrong, but what can we do to avoid it? There are many ways to fight this problem, but this is in my opinion the best approach: Let the kid set up the store account on the device and set own passwords. Just like an adult would use a phone, except that there’s no payment method registered. Never enter your credit card number on the kid’s device. On Android, get familiar with Google Play Family. This feature enables you to purchase stuff for your kid on your own device. On iPhone, send apps or money as gifts. There may be applications that bypass the store and handle credit card transactions directly. This can typically be handled with vouchers or other prepaid payment methods instead. The application usually guides the users and list all supported methods. Let’s also take a look at the hard way. Follow these instructions if you for some reasons must have your credit card registered as a payment method on the kid’s device. Make sure the store is protected with a good password that only you know. Make sure the kid isn’t watching too closely when you enter it. Make sure the store is set up to require the password every time a purchase is made. Make sure the store account is attached to an e-mail only you have access to. Make sure the e-mail password is decent and not known to your kid. Make sure your phone’s security settings are decent. Use a PIN or password your kid doesn’t know and make sure it locks automatically quickly enough. Even better, do not have the e-mail of your kids store account on your phone. Access it through web mail when needed. So this is after all a quite complex issue. There are many variations and other ways to deal with the problem. Did I miss some simple and clever way? Write a comment if you think I did. And finally. Yes, there’s also many ways to lock the kids out of the store completely. This does no doubt solve some problems, but I don’t think it’s a good idea. They will after all live their lives in a world where digital devices and services are as natural as breathing. They deserve the opportunity to start practicing for that right now. Let them browse the store and discover all the fun stuff. And be part of the group and use all the same apps as their friends. Let them have fun with the phone and learn, even if they will learn some things the hard way. Don’t ruin it for them. Safe surfing, Micke
This has got to be the quickest Quick Tip of all. Literally. With just one click, it's too easy not to do. You know your computer can be infected. But did you know your router can, too? And because most people just aren't aware of it, if your router is compromised, it could stay that way a long time without you ever knowing. Unless, of course, you use our free Router Checker. No need to download anything. Just visit the page and click to start the check. Hacking your router is just one more method attackers use to display fraudulent advertising, spread malware, or steal your private account credentials. It's called DNS hijacking. When you type in a website name, say "cooldomain.com," you're directed to a DNS server that will find the website's IP address - say "44.567.54.69" for example, and display the website you need. But in a DNS hijack, hackers change your router's settings to direct you to a rogue DNS server. The rogue server will give a malicious IP address, purposely directing you to a website that may look like the one you want, but it's not. Here's an example: Let's say you want to log into your bank account. But unbeknownst to you, you're directed to a look-alike website that's not really your bank. You enter in your bank username and password. Now the attacker has your credentials, which he (or she) can use. F-Secure Router Checker makes sure the settings on your computers, phones, and routers connect to safe DNS servers. So what are you waiting for? Visit the F-Secure Router Checker page and click on "Check Your Router." It's too easy not to do.
