Studies have said public speaking makes as many as 3 out of 4 people anxious. But that was before Facebook.
The 650 million people on Facebook suggest that most of us are getting over—or want to get over—that fear of communicating (or at least sharing pictures) in public. In just a few years, Twitter, YouTube and Facebook have given billions of people the chance to connect to an audience they would never had access to before.
But now that you’re becoming comfortable in public, you may begin to wonder: Am I revealing too much? In a world with the NSA, TMZ and Wikileaks, do I have any privacy? Is it possible to be a public person and still protect my information from being misused?
The more visible, attractive or rich you are, the more you’re a target for the haters, the stalkers and online criminals of the 21st century. Heck, if you have a credit card, you’re a target for both the online criminals and unscrupulous marketers of the world.
Sharing personal information in an age where data can travel faster than lightning requires a 21st century view of data privacy. Some think it’s vain to worry about privacy. But don’t think about your ego, think about social engineering.
Wiktionary describes social engineering as “The practice of tricking a user into giving, or giving access to, sensitive information, thereby bypassing most or all protection.” Criminals have discovered that human error is the easiest vulnerability to exploit. If you’re not careful, your private data (or even public data) can be used to fool you into making mistakes that even your award-winning Internet Security can’t prevent.
Ignorance may be bliss, but it’s not an excuse. Once your private data is stolen, you’ll have to deal with the consequences. The good news is that you can do a lot to make your data more secure
My nephew once told me, “Facebook is so easy that even old people can use it.” And by old people, he meant me.
I agree with my nephew. Most people who use social media don’t suffer significant negative consequences for doing so—or there wouldn’t be millions of new people trying it every day. Stories of people being fired or arrested for what they’ve done on Facebook are rare. But they get lots of attention because Facebook is the superstar everyone knows.
Only a small percentage of those on social media fall victim to the worst of identity theft, malware or scams. And that’s still too many people suffering needlessly—especially because most of these scourges are avoidable.
If you learned to manage the benefits and risks of email, you can do the same for social media. Here a few things you can do to help keep your private data private.
1. Decide why you’re social networking.
For some, social networking is an extension of your private life. You mostly interact with people you know or would like to know in the real world. The main topics of conversation are personal. Even when you delve into entertainment or politics or sports, it’s about sharing opinions to have fun and connect. Intimacy is the goal so private things are often shared nonchalantly. For instance, you might reveal what you did on a day when you played hooky from school or work.
For others, social networking is like interacting at a conference. You’re seeking out people in your industry or whom you admire. Conversation is like a cocktail party—being interesting and on-topic matters. When you talk about entertainment or politics or sports, it’s a way to network and establish trust. You want people to feel like they know you, but getting too personal too fast raises red flags. For instance, you may reveal what you did on your vacation but only in a way that you wouldn’t mind your boss reading.
For a growing number of people, social network is a chance to build a little fame or fortune. You’re looking for an audience who trusts and enjoys you to the point you might even sell them things. You converse with fellow influencers and friends but you also broadcast for a targeted or general audience. When you talk about entertainment or politics or sports, you’re entertaining or engaging an audience while establishing expertise. You may share extremely private details or never talk about your personal life. Either way, you’re establishing a persona that’s relatable to the audience you’re trying to attract. For instance, you may reveal a joke a well-known person shared with you.
By the time you’re out of college for a few years, most people have tried out some variation of each of these approaches to social media. And your approach definitely affects your data security.
The rule is: the bigger the audience you seek, the more you have to think about the information you share.
All of us have to protect our ID, account and phone numbers, our address and our Mother’s maiden name. But if you’re an aspiring Disney star or class president, you have to think about which pictures you take—since you know they’ll all be posted eventually. And George Clooney probably shouldn’t use Foursquare to share his location unless he wants to spend his day shaking hands or filing restraining orders.
We all need to be cautious about sharing details that can be used to scam us. If you achieve, or accidentally achieve, fame, your privacy will become even more precious. So if you want to be internet famous, you need to be savvy about which information you share online—or you’ll have to hire people who are.
2. Secure your systems
Don’t use the default password for your voicemail or anything. Use strong, unique passwords for all your accounts. Don’t use work email addresses or passwords for social accounts. Put security software on your PC and your mobile device, if possible. Password protect your Wi-Fi networks. Turn on secure browsing on Facebook. Put a remote lock on your mobile phone. Always lock your PC and mobile devices when you aren’t using them. Keep your system and application software updated. (Our free Health Check makes that easy.) Turn off GPS on your phone and pictures if you don’t want strangers to know your location.
3. Choose services you trust
4. On a social network, your information could be shared with everyone– no matter what your privacy settings are.
Twitter is simple. There are two privacy settings: everyone or “Protect my tweets”. But even if you go with the protected option, your approved followers can still retweet your information to everyone. Facebook’s privacy settings are much more complex. They’re so complex that it almost feels like you should get college credits for really using them. Going with “Friends Only” is a good start, then you have to decide if you want your page on Google (if you don’t want your Facebook page to show up on Google, go to Account > Privacy Settings > Apps and Websites: Edit your settings > Public Search: Edit Settings > Uncheck Enable public search) and if you want to automatically share your information with other websites.
The safest rule is: get your settings right and still assume that what you post could go public so only share information you wouldn’t mind a future boss (or fan) seeing. NEVER share information that could be used to crack your passwords. Also keep in mind that the information you’re sharing that could be used by identity thieves and social engineers.
5. Be available or don’t
There is a difference between following and friending people. You can follow a lot of people but our brains can only handle around 130 friends. Rejecting or ignoring friend requests can be emotionally difficult, but your privacy is more important than others’ feelings. I say follow anyone on Twitter but on Facebook I’d recommend only befriending people you know or trust. And realize that the person is your friend, not their links. If anyone begins to spam you, let them know the problem. If they keep spamming, unfriend them. If anyone harasses you at all, block their communication. If you’re threatened, contact law enforcement.
You have the right to keep your private data secure while living your digital life to the fullest. All you have to do is respect your own data privacy and do your best to make sure that the people and businesses you interact with do the same.
Every time you go online, your personal privacy is at risk – it’s as simple as that. Whether you’re creating an account on a website, shopping, or just browsing, information like your email, IP address and browsing history are potential targets for interested parties. All too often, that information is sold on or sometimes even stolen without you even knowing it. And the threats to our online privacy and security are evolving. Fast. As F-Secure’s Online Protection Service Lead, Christine Bejerasco’s job is to make life online safer and more secure. “We’re basically online defenders. And when your job is to create solutions that help protect people, the criminals and attackers you’re protecting them against always step up their game. So it’s like an arms race. They come up with new ways of attacking users and our job is to outsmart them and defend our users,” Christine says. Sounds pretty dramatic, right? Well that’s because it is. While it used to be that the biggest threat to your online privacy was spam and viruses, the risks of today and tomorrow are potentially way more serious. “Right now we’re in the middle of different waves of ransomware. That’s basically malware that turns people’s files into formats they can’t use. We’ve already seen cases of companies and individual people having their systems and files hijacked for ransom. It’s serious stuff and in many cases very sad. If your online assets aren’t protected right now you should kind of feel like you’re going to bed at night with your front door not only unlocked but wide open.” Christine and her team of 11 online security superheroes (eight full-time members and three super-talented interns) are on the case in Helsinki. Here’s more on Christine and her work in her own words: Where are you from? The Philippines Where do you live and work? I live in Espoo and work at F-Secure in Ruoholahti, Helsinki. Describe your job in 160 characters or less? Online guardian who strives to give F-Secure users a worry-free online experience. One word that best describes your work? Engaging How long is a typical work day for you? There is no typical workday. It ranges from 6 – 13 hours, depending on what’s happening. What sparked your interest in online security? At the start it was just a job. As a computer science graduate, I was just looking for a job where I could do something related to my field. And then when I joined a software security company in the Philippines, I was introduced to this world of online threats and it’s really hard to leave all the excitement behind. So I’ve stayed in the industry ever since. Craziest story you’ve ever heard about online protection breach? Ashley Madison. Some people thought it was just a funny story, but it had pretty serious consequences for some of the people on that list. Does it frustrate you that so many people don’t care about protecting their online privacy? Yeah, it definitely does. But you grow to understand that people don’t value things until they lose it. It’s like insurance. You don’t think about it until something bad happens and then you care. What’s your greatest work achievement? Shaping the online protection service in the Labs from its starting stages to where we are today. What’s your idea of happiness? Road trips and a bottle of really good beer. Which (non-work-related) talent would you most like to have? Hmmm… tough. Maybe, stock-market prediction skills? What are your favorite apps? Things Stumbleupon What blogs do you like? Security blogs (F-Secure Security blog of course and others – too many to list.) Self-Help Blogs (Zen Habits, Marc and Angel, etc.) Who do you admire most? I admire quite a few people for different reasons. Warren Buffett for his intensity, simplicity and generosity. Mikko Hyppönen for his idealism and undying dedication to the online security fight. And Mother Theresa for embodying the true meaning of how being alive is like being in school for your soul. Do you ever, ever go online without protection? Not with systems associated to me personally, or with someone else. But of course, when we are analyzing online threats, then yes.

The Sony hack of late 2014 sent shock waves through Hollywood that rippled out into the rest of the world for months. The ironic hack of the dubious surveillance software company Hacking Team last summer showed no one is immune to a data breach - not even a company that specializes in breaking into systems. After a big hack, some of the first questions asked are how the attacker got in, and whether it could have been prevented. But today we're asking a different question: whether, once the attacker was already in the network, the breach could have been detected. And stopped. Here's why: Advanced attacks like the ones that hit Sony and Hacking Team are carried out by highly skilled attackers who specifically target a certain organization. Preventive measures block the great majority of threats out there, but advanced attackers know how to get around a company's defenses. The better preventive security a company has in place, the harder it will be to get in…but the most highly skilled, highly motivated attackers will still find a way in somehow. That's where detection comes in. Thinking like an attacker If an attacker does get through a company's defensive walls, it's critical to be able detect their presence as early as possible, to limit the damage they can do. There has been no official confirmation of when Sony's actual breach first took place, but some reports say the company had been breached for a year before the attackers froze up Sony's systems and began leaking volumes of juicy info about the studio's inner workings. That's a long time for someone to be roaming around in a network, harvesting data. So how does one detect an attacker inside a network? By thinking like an attacker. And thinking like an attacker requires having a thorough knowledge of how attackers work, to be able to spot their telltale traces and distinguish them from legitimate users. Advanced or APT (Advanced Persistent Threat) attacks differ depending on the situation and the goals of the attacker, but in general their attacks tend to follow a pattern. Once they've chosen a target company and performed reconnaissance to find out more about the company and how to best compromise it, their attacks generally cover the following phases: 1. Gain a foothold. The first step is to infect a machine within the organization. This is typically done by exploiting software vulnerabilities on servers or endpoints, or by using social engineering tactics such as phishing, spear-phishing, watering holes, or man-in-the-middle attacks. 2. Achieve persistence. The initial step must also perform some action that lets the attacker access the system later at will. This means a persistent component that creates a backdoor the attacker can re-enter through later. 3. Perform network reconnaissance. Gather information about the initial compromised system and the whole network to figure out where and how to advance in the network. 4. Lateral movement. Gain access to further systems as needed, depending on what the goal of the attack is. Steps 2-4 are then repeated as needed to gain access to the target data or system. 5. Collect target data. Identify and collect files, credentials, emails, and other forms of intercepted communications. 6. Exfiltrate target data. Copy data to the attackers via network. Steps 5 and 6 can also happen in small increments over time. In some cases these steps are augmented with sabotaging data or systems. 7. Cover tracks. Evidence of what was done and how it was done is easily erased by deleting and modifying logs and file access times. This can happen throughout the attack, not just at the end. For each phase, there are various tactics, techniques and procedures attackers use to accomplish the task as covertly as possible. Combined with an awareness and visibility of what is happening throughout the network, knowledge of these tools and techniques is what will enable companies to detect attackers in their networks and stop them in their tracks. Following the signs Sony may have been breached for a year, but signs of the attack were there all along. Perhaps these signs just weren't being watched for - or perhaps they were missed. The attackers tried to cover their tracks (step 7) with two specific tools that forged logs and file access and creation times - tools that could have been detected as being suspicious. These tools were used throughout the attack, not just at the end, so detection would have happened well before all the damage was done, saving Sony and its executives much embarrassment, difficult PR, lost productivity, and untold millions of dollars. In the case of Hacking Team, the hacker known as Phineas Fisher used a network scanner called nmap, a common network scanning tool, to gather information about the organization’s internal network and figure out how to advance the attack (step 3). Nmap activity on a company internal network should be flagged as a suspicious activity. For moving inside the network, step 4, he used methods based on the built-in Windows management framework, PowerShell, and the well-known tool psexec from SysInternals. These techniques could also potentially have been picked up on from the way they were used that would differ from a legitimate user. These are just a few examples of how a knowledge of how attackers work can be used to detect and stop them. In practice, F-Secure does this with a new service we've just launched called Rapid Detection Service. The service uses a combination of human and machine intelligence to monitor what's going on inside a company network and detect suspicious behavior. Our promise is that once we've detected a breach, we'll alert the company within 30 minutes. They'll find out about it first from us, not from the headlines. One F-Secure analyst sums it up nicely: "The goal is to make it impossible for an attacker to wiggle his way from an initial breach to his eventual goal." After all, breaches do happen. The next step, then, is to be prepared. Photo: Getty Images
Yet another big vulnerability in the headlines. The Metaphor hack was discovered by Israel-based NorthBit and can be used to take control over almost any Android device. The vulnerability can be exploited from video files that people encounter when surfing the web. It affects all versions of Android except version 6, which is the latest major version also known as Marshmallow. But why is this such a big deal? Severe vulnerabilities are found all the time and we receive updates and patches to fix them. A fast update process is as a matter of fact a cyber security cornerstone. What makes this issue severe is that it affects Android, which to a large extent lack this cornerstone. Android devices are usually not upgraded to new major versions. Google is patching vulnerabilities, but these patches’ path to the devices is long and winding. Different vendors’ practices for patching varies a lot, and many devices will never receive any. This is really a big issue as Android’s smartphone market share is about 85% and growing! How is this possible? This underlines one of the fundamental differences between the Android and iOS ecosystems. Apple’s products are planned more like the computers we are used to. They are investments and will be maintained after purchase. iOS devices receive updates, and even major system upgrades, automatically and free of charge. And most users do install them. Great for the security. Android is a different cup of tea. These devices are mostly aimed at a cheaper market segment. They are built as consumables that will be replaced quite frequently. This is no doubt a reasonable and cost-saving strategy for the vendors. They can focus on making software work on the currently shipping devices and forget about legacy models. It helps keeping the price-point down. This leads to a situation where only 2,3% of the Android users are running Marshmallow, even half a year after release. The contrast against iOS is huge. iOS 9 has been on the market about the same time and already covers 79% of the user base. Apple reported a 50% coverage just five days after release! The Android strategy backfires when bugs like Metaphor are discovered. A swift and compete patch roll-out is the only viable response, but this is not available to all. This leaves many users with two bad options, to replace the phone or to take a risk and keep using the old one. Not good. One could think that this model is disappearing as we all grow more and more aware of the cyber threats. Nope, development actually goes in the opposite direction. Small connected devices, IoT-devices, are slowly creeping into our homes and lives. And the maintenance model for these is pretty much the same as for Android. They are cheap. They are not expected to last long, and the technology is developing so fast that you would be likely to replace them anyway even if they were built to last. And on top of that, their vendors are usually more experienced in developing hardware than software. All that together makes the IoT-revolution pretty scary. Even if IoT-hacking isn’t one of the ordinary citizen’s main concerns yet. So let’s once again repeat the tree fundamental commands for being secure on-line. Use common sense, keep your device patched and use a suitable security product. If you have a system that provides regular patches and updates, keep in mind that it is a valuable service that helps keeping you safe. But it is also worth pointing out that nothing as black and white. There are unfortunately also problematic update scenarios. Safe surfing, Micke Photo by etnyk under CC
