You may have heard about Storify. A new tool that you can use to publish private conversations in Facebook. Scary, isn’t it? Or that’s at least the angle many headlines take. But the full picture is a lot less dramatic. In fact, Storify does not enable you to do anything that you couldn’t do before, it just makes it easier. And it is an excellent reminder about the risks with so called private messages.
Most legislations provide a fairly high level of protection for messages in transit. The goal is to prevent 3rd parties from eavesdropping and tampering with the messages. But what many forget is that the parties involved in the communication have rights to use the message. It means that the recipient has fairly free hands to use what you write as soon as the message hits the inbox. Your only protection is really your trust in the other part. You may write things that both parties understand should remain private, and it may be sufficient protection today. But what about the future? We all know that trust can change. Many who have gone through a divorce know that the person you trust the most of all may become your worst enemy.
So what about Facebook and Storify? It’s just a good reminder about what can happen to “private” messages. The same threat exists in any kind of messaging service. Not only on the Internet, phone calls can be recorded and misused as well. Letters on paper can be copied, scanned and published. Facebook didn’t provide tools for publishing private messages, but that never prevented users from using copy-paste or taking screenshots of the messages. And our good old e-mail is no better. It has a button called Forward for this purpose.
The only thing that can protect you from this kind of leaks is to not write things that would be embarrassing if published. Be polite and adopt a no-nonsense attitude even in private communications. Think twice before reveling secrets over electronic communication systems. Even if you use encryption it only protects you against 3rd parties, not against the recipient. And last but not least. Do not turn your friends into enemies. That’s probably the biggest reason for leaked private messages.

At Re:publica 2015, our Chief Research Officer Mikko Hypponen told the main stage crowd that the world's top scientists are now focused on the delivery of ads. "I think this is sad," he said. [youtube https://www.youtube.com/watch?v=pbF0sVdOjRw?rel=0&start=762&end=&autoplay=0] To give the audience a sense of how much Twitter knows about its users, he showed them the remarkable targeting the microblogging service offers its advertisers. If you use the site, you may be served promoted tweets based on the following: 1. What breakfast cereal you eat. 2. The alcohol you drink. 3. Your income. 4. If you suffer from allergies. 5. If you're expecting a child. And that's just the beginning. You can be targeted based not only on your recent device purchases but things you may be in the market for like, say, a new house or a new car. You can see all the targeting offered by logging into your Twitter, going to the top right corner of the interface, clicking on your icon and selecting "Twitter Ads". Can Twitter learn all this just based on your tweets and which accounts follow? No, Mikko said. "They buy this information from real world shops, from credit card companies, and from frequent buyer clubs." Twitter then connects this information to you based on... your phone number. And you've agreed to have this happen to you because you read and memorized the nearly 7,000 words in its Terms and Conditions. Because everyone reads the terms and conditions. Full disclosure: We do occasionally promote tweets on Twitter to promote or digital freedom message and tools like Freedome that block ad trackers. It's an effective tool and we find the irony rich. Part of our mission is to make it clear that there's no such thing as "free" on the internet. If you aren't paying a price, you are the product. Aral Balkan compares social networks to a creepy uncle" that pays the bills by listening to as many of your conversations as they can then selling what they've heard to its actual customers. And with the world's top minds dedicated to monetizing your attention, we just think you should be as aware of advertisers as they are as of you. Most of the top URLs in the world are actually trackers that you never access directly. To get a sense of what advertisers learn every time you click check out our new Privacy Checker. Cheers, Jason
This is the first in a series of posts about Cyber Defense that happened to real people in real life, costing very real money. A rainy, early spring day was slowly getting underway at a local council office in a small town in Western Poland. It was a morning like any other. Nobody there expected that this unremarkable day would see a series of events that would soon affect the entire community... Joanna Kaczmarek, a Senior Specialist in the council’s Accounting Department, rushed into her office a little late, but in a good mood nonetheless. Before getting down to work, she brewed herself a cup of coffee and played some music on her computer. Several days earlier, she had finally installed a music app on her PC so she could listen to her favourite tunes while she worked. This had taken some effort though, as she had needed administrator’s access to her computer. It took a lot of pleading and cajoling, but after a week the IT guy finally gave in. Joanna had no idea that she was opening a dangerous gap in the council’s IT system. That morning, Joanna launched, as she had countless times before, a government issued budget management application. With a few clicks, she made a transfer order for nearly twenty thousand zloty. The recipient of the money was a company that had won the contract for the renovation of a main road in the town. The whole operation took seconds. Two days later, the owner of the company phoned Joanna, asking about the advance he was supposed have received. “I can’t get the work started without that money”, he complained in an annoyed voice. Joanna was a little surprised and contacted the bank. The bank confirmed the operation, saying that there was nothing suspicious about it. Joanna, together with the Head of the IT Department, carefully ran back over the events of the day of the transfer. They found nothing out of the ordinary, so started checking what was happening on Joanna’s computer around the time before the transfer date. They soon found something: nearly a week prior to the date of the missing transfer, Joanna had received an email from the developer of the budget management software. For Joanna, the message hadn’t raised any red flags; the email contained a reminder about a software update and looked very legitimate. It contained the developer’s contact data, logo and telephone number. Everything was in order… Everything except for a change of one letter in the sender’s address. Joanna hadn’t noticed – a “t” and an “f” look so alike when you read quickly, don’t they? Unaware of the consequences, Joanna followed the link that was to take her to the update website. With just one click of her mouse she started a snowball of events that ultimately affected each and every resident of the town. Instead of the “update”, she downloaded dangerous spyware onto her computer. In this way, the cybercriminals who orchestrated the attack learnt that the woman was a Senior Specialist in the Accounting Department and was responsible for transferring money, including EU funds. The thieves lured Joanna into a digital trap, tricking her into installing software that replaced bank account numbers “on the fly”. As she was processing the transaction, the hackers replaced the recipient’s account details with their own, effectively stealing the money. Joanna would have been unable to install the fake update if she hadn’t obtained the administrator’s rights she’d needed for her music app. All she had wanted was to listen to some music while she worked. If only she had known what the consequences would be... After the attack was discovered, the Police launched an investigation. Joanna was just one of many victims. Investigators discovered that the malware infection was likely to have targeted computers used by local government workers in hundreds of municipalities across Poland. Law enforcement authorities haven’t officially disclosed how much money was stolen, but given the fact that losses may have been underreported, the estimated figures are in the millions of zlotys. On the top of that, Joanna’s town had to wait months for the completion of the roadwork. This was one of the largest mass cyber-attacks against local government in Poland. It certainly won’t be the last one... For small and medium sized enterprises, the average financial loss as the result of a cyber security incident is on average 380 000€. The risk and the lost is real. Don’t be an easy target. We help businesses avoid becoming an easy victim to cyber attacks by offering best in class end-point protection and security management solutions trusted by millions.
F-Secure Labs reported this week on a new WhatsApp scam that’s successfully spammed over 22,000 people. Spam seems to be as old as the Internet itself, and is both a proven nuisance AND a lucrative source of revenue for spammers. Most people don’t see what goes on behind the scenes, but spammers often employ very sophisticated schemes that can expose web surfers to more than just ads for Viagara or other “magic beans”. Spam typically tries to drive Internet traffic by tricking people into clicking certain websites, where scammers can bombard unsuspecting web surfers with various types of advertising. Profit motives are what keep spammers working hard to circumvent spam blocks, white lists, and other protective measures that people use to try and fight back – and it can pay off. Numerous spammers have been indicted and suspected of generating hundreds of thousands of dollars in revenue from their spam campaigns, with one study projecting that spammers could generate in excess of 3.5 million dollars annually. While most spam circulates via e-mail, the popularity of services like WhatsApp is giving spammers new resources to exploit people, and new ways to make money. Here’s a few ways spammers and cyber criminals are using WhatsApp to make money off users: Following Malicious Links: One way that cyber criminals use WhatsApp to scam people is to trick them into following malicious links. For example, a recent scam sent SMS messages to WhatsApp users telling them to follow a link to update the app. But the message was not from WhatsApp, and the link didn’t provide them with any kind of update. It signed them up for an additional service, and added a hefty surcharge to victims' phone bills. Sending Premium Rate Messages: Premium rate SMS sending malware was recently determined by F-Secure Labs to be the fastest growing mobile malware threat, and WhatsApp gives cyber criminals a new way to engage in this malicious behavior. Basically the users receive a message that asks them to send a response – “I’m writing to you from WhatsApp, let me know here if you are getting my messages”, “Get in touch with me about the second job interview”, and various sexual themed messages have all been documented. Responding to these messages automatically redirects your message through a premium rate service. Spanish police claim that one gang they arrested made over 5 million euros using this scheme – leaving everyday mobile phone users to foot the bill. Manipulating Web Traffic: A lot of spam tries to direct web traffic to make money off advertising. As you might imagine, this means they have to get massive numbers of people to look at the ads they’re using for their scams. Scammers use WhatsApp to do this by using the app to spread malware or social engineer large numbers of people to visit a website under false pretenses. F-Secure Labs found that people were being directed to a website for information on where they could get a free tablet. In March there was a global spam campaign claiming people could test the new WhatsApp calling feature. Both cases were textbook scams, and instead of getting new tablets or services, the victims simply wasted their time spreading misleading spam messages and/or exposing themselves to ads. WhatsApp and other services are great for people, but like any new software, requires a bit of understanding to know how to use. Hopefully these points give WhatsApp users a heads up on how they can avoid spam and other digital threats, so they can enjoy using WhatsApp to chat with their friends. [ Image by Julian S. | Flickr ]
