Did you know that in most cases, you do not realize when you have been hit by malware?
At least the site that has been said to be the source for a recent attack on Facebook, Apple and Twitter, claims to have known nothing of being compromised before reading about the security breaches on the news. Bloomberg.com tells the iPhone software development site was most likely used for a waterhole attack by East-European criminals.
Most malware programs use the vulnerabilities in popular software to get installed so that you do not even recognize the threat. New exploits are detected around the world all the time, and for example Java is usually at the top of the targeted software list. The amount of malware is alarmingly high, almost 60% of respondents of a Ponemon study confirmed over 25 malware incidents in their environments each month.
Sophisticated malware contaminates your pc or mobile just by a visit to an infected website, by opening an Office document, pdf or other document with an exploit. You will not notice anything peculiar. The days of the very obvious spam mails with malware in them is over. Today, the mails and sites with infection look just as original and trustworthy as any other and you would be “happily” unaware of anything out of the ordinary going on. Until the reality hits in and the repercussions of the attack get real.
The biggest amount of vulnerabilities comes not from the operating system, but from 3rd party software. Exploit kits are in the wild only a few moments after a fix to a vulnerability is released.
Administrators currently don’t necessarily have visibility to what 3rd party software is installed. Keeping up with all the patches and updates for all used software, and making the necessary updates takes a lot of time and effort. For example, this June alone, my colleagues counted well over 100 vulnerabilities just in the most common software for Windows workstations.
To make it more challenging, usually, after all the necessary updates are done, the admin has to start it all over again when new security updates are available. Often as soon as the next day…
The F-Secure experts can offer a solution: Software Updater not only studies the available patches, but also installs security updates automatically and covers both the operating system and 3rd party software. However, administrators can easily define exclusions for the automatic mode if and when necessary.
If you read our post about why you should travel with glitter nail polish, you know we love unconventional OPSEC advice that keep strangers out of your business. That's why this quote in a recent GQ profile of Kim Kardashian, which was first pointed out by LA Times editor Amy Fiscus, stood out: "She's frighteningly organized: She tells me that before bed she deletes every single text message and e-mail from her phone, unless it's something she still needs to respond to." Is this good OPSEC? We asked one of our resident experts Camillo Särs and he was intrigued. "Yes – the practice of deleting any unnecessary copies as soon as possible is definitely good OPSEC," he explained. "Clearly that is not the actual intent here, but effective, nevertheless!" So be like the woman who broke the internet, and consider getting rid of anything you don't need to keep as soon as possible. And if you're about to go on vacation, here's a quick OPSEC tip for your email out-of-office message, which could be helping criminals trying to phish you. Is there an OPSEC tip you picked up that you've picked up and feel like sharing? Let us know in the comments.
In Finland, there is this thing called juhannus. A few years ago, our former colleague Hetta described it like this: Well, Midsummer – or juhannus – as it is called in Finnish, is one of the most important public holidays in our calendar. It is celebrated, as you probably guessed, close to the dates of the Summer Solstice, when day is at its longest in the northern hemisphere. Finland being so far up north, the sun doesn’t set on juhannus at all. Considering that in the winter we get the never ending night, it’s no surprise we celebrate the sun not setting. So what do Finns do to celebrate juhannus? I already told you we flock to our summer cottages, but what then? We decorate the cottage with birch branches to celebrate the summer, we stock up on new potatoes which are just now in season and strawberries as well. We fire up the barbecue and eat grilled sausages to our hearts content. We burn bonfires that rival with the unsetting sun. And we get drunk. If that isn't vivid enough, this video may help: [protected-iframe id="f18649f0b62adf8eb1ec638fa5066050-10874323-9129869" info="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fsuomifinland100%2Fvideos%2F1278272918868972%2F&show_text=0&width=560" width="560" height="315" frameborder="0" style="border: none; overflow: hidden;" scrolling="no"] And because the celebration is just so... celebratory, it's easy to lose your phone. So here are a few ways to prepare yourself for a party that lasts all night. 1. Don't use 5683 as your passcode. That spells love and it's also one of the first passcodes anyone trying to crack into your phone will try. So use something much more creative -- and use a 6-digit code if you can on your iPhone. You can also encrypt your Android. 2. Write down your IMEI number. If you lose your phone, you're going to need this so make sure you have it written down somewhere safe. 3. Back your content up. This makes your life a lot easier if your party goes too well and it's pretty simple on any iOS device. Just make sure you're using a strong, unique password for your iCloud account. Unfortunately on an Android phone, you'll have to use a third-party app. 4. Maybe just leave it home. Enjoy being with your friends and assume that they'll get the pictures you need to refresh your memory. And while you're out you can give your phone a quick internal "clean" with our free Boost app. [Image by Janne Hellsten | Flickr]
Mikko Hyppönen -- our Chief Research Officer and probably the most famous code warrior ever to come out of Finland -- likes to point out that he was born the same year as the internet. Jani -- the ten-year-old from Helsinki who made international news by earning Instagram's top bug bounty prize for uncovering a security flaw in the photo-sharing site -- was born a couple a years after Facebook was invented in 2004 and just four years before Instagram went online in 2010. And he's already made some history. Jani discovered a flaw in the site that would have allowed him -- or anyone -- to delete content from any user from the site, even stars with tens of millions of followers including Taylor Swift, Selena Gomez and Beyonce. Like any good white-hat hacker he didn't take advantage of the vulnerability. Instead, he reported the bug to Facebook, which now owns the app, directly. His maturity paid off. Even though he is not technically old enough to use the site according Instagram's terms and conditions, he's become the youngest person ever to win a $10,000 bug bounty, which he's used to purchase a soccer ball, a bike and other essential gear for being ten. To celebrate his feat, F-Secure Labs invited Jani to visit our headquarters for a hamburger and a tour. The visit gave our experts a chance to share their stories about how they were drawn to cybersecurity. Mikko learned to love computers from his mother who was in the industry. Päivi was guided into the field by her father and discovered that she has a passion for rooting out spam. When Tomi was a kid striving to learn the rules of the coin games his friends played so he could hack them and win, he recognized that he didn't see the world like everyone else. Jani has already discovered the same thing. Though he finds plenty of time for school and playing with his friends, he spends 2-3 hours during his off days hunting for vulnerabilities and looking out for new bug bounty programs -- like our own -- that allow him to test his skills. How did he find the vulnerability in Instagram? First he created two accounts. He posted a comment using one account and then just using the publicly available content id number he was able to delete the comment using the other. Immediately he recognized the potential for such a flaw to be exploited. Mikko and Tomi were impressed by how Jani used Linux and Burp Suite -- a tool that pros like the analysts in our Labs use to analyze network traffic -- to help identify the bug. While he used to be interested in a career in video games, Jani says he's now thinking about becoming a cybersecurity specialist. Mikko and Tomi advised him to finish school and stay on the right side of the law. They also invited him to spend a week or two working at the Labs to see how he likes the job, when he's old enough. He's planning on taking them up on the offer, saying that F-Secure looks like a "fun and cool" place to work. Nice. We're always looking for new talent and even Mikko may retire one day.
