Have You Been Hacked?

Being hacked is the single biggest fear for most computer users. Many people believe the first sign of strange behavior or errors on their PC is a sign of being hacked. But are hackers really inside your machine, roaming around madly and stealing your information? Or should we be on the lookout for other more subtle signs? What does being hacked really look like and what can I do to help prevent it happening?

There is an important distinction to make between being attacked by a hacker and being infected with a virus or malware. Virus software and malware are automated processes designed to damage your system and / or steal your data. There are of course ways that we can defeat these processes, but what if we are instead being hacked and what are some of the signs?

Passwords not working

One of the first steps a hacker might take is to change your computers login passwords. By doing so, not only do they ensure future access to the machine, they prevent you from accessing the system to stop them. For the hacker, this is a crucial step that keeps them in control. With this in mind, we always want to make sure to keep on top of our own login details and how often we change them.

Security notifications from online services

A lot of online services track which device and location you logged into your account from last. If your account is accessed from a new device or a different country it might trigger an automated email or SMS asking if this new login is from you.

If you have just logged into a service from a new computer, tablet, or phone; receiving an email that asks “hey, is this you?” need not be cause for alarm. If you haven’t, it may be time to investigate further. This feature is a very important part of information security and may be a key first step to identify someone else gaining access to your account.

Bank accounts missing money or strange transactions

The end goal for the majority of today’s hackers is typically to profit from their crimes by taking money from people online. As such, it pays to keep a regular eye on your financial transactions to make sure you know what money is coming and going from your account.

You may see a large sum missing where hackers have attempted to take as much as they can in a single transaction. On the other hand unknown or unusual small transactions may be attackers testing the login details they have, to confirm that they work.

Loss of mobile phone or land line connectivity

Phone interruption is a symptom that few people expect but can occur when hackers attack. Many banks and online services use a security feature known as two-factor or multi factor authentication (2FA or MFA). They do this by sending a code to your phone or app when you log in, you then have to enter this code to confirm who you are.

Hackers can try to work around this by calling your phone provider to report your phone as lost or stolen. During this call, they will request your phone number be transferred to a new sim card or redirected to another number that they control. When your bank sends its regular two-factor authentication code to the number registered, it goes instead to the hacker who then can log in. From your perspective the phone service will simply stop working, so if this happens contact your provider ASAP.

Social engineering

Another technique that may not even include a technical method is called social engineering. Social engineering is when hackers try to obtain confidential information by manipulating people to freely give them this information. This can be done in many different ways. Some examples are:

  • A strangers phones your office and may pretend to be a customer or supplier but asks for personal or confidential information.
  • A person claiming to be a supplier contacts you and asks you to change the bank account you send payments to.
  • Some one attends your premises for some reason but you have no prior knowledge of who they are or why they are they are requesting access.
  • Some one phones and claims to be from the technical department of your ISP or maybe even Microsoft and requests remote access to your computer.
  • You receive an email claiming to be from the boss or management asking you to do something which doesn’t seem right – like purchasing iTunes vouchers or asking to authorize payment to a new supplier.

Keeping vigilant and maintaining security

These are only some of the techniques that hackers can try to use to gain access to your systems and accounts. It pays to be extra vigilant and pay close attention to the signs and signals that indicate you may have been hacked. It may als

What You Need to Know About Facebook Privacy

Facebook PrivacyA lot of people use Facebook but finding the balance between privacy and Facebook fun can be challenging. It allows us to connect with friends near and far but also it publicly shares information that just a few years ago, we’d never dream of putting online. With a Facebook search you can look for people based on where they went to school, town they live in, clubs they belong to, who they’re related to… but when is it too much information?

Your birthday is the first piece of info collected by Facebook when you sign up and it is great getting birthday wishes from friends and family when it appears in their news feed. But while your friends are sending you balloons and funny memes, your birthday is now public knowledge. It may seem harmless, but when you call your bank or other institution, what’s the first question they ask to verify your identity? Your birthday! Some companies and organisations even ask questions like ‘which high school did you go to?’ assuming this is knowledge that only you would know. Except… a lot of people have publicly shared it on Facebook. Whoops!

Then there are the stories of people who have lost their jobs after less-than-wholesome pictures or comments have gone public. If you want to protect your reputation, you may not want pictures from last weekend’s private party showing up online. While you can’t control what others do with photos they take of you, you can control whether or not you are tagged in Facebook in them.

Fortunately, there are settings in Facebook that allow you to control who can see what information and what happens when you’re tagged in a photo. Despite what rumours you may have heard or seen floating around, you do have complete control over your Facebook privacy and it is easy to adjust.

How to Check and Adjust Your Facebook Privacy Settings

Here are some settings you can easily change within Facebook to help secure your privacy and see who can see what on your profile. These steps assume you are logged into Facebook via a browser (using an app on your phone or tablet may be different).

See what your account looks like to an outsider

To see what others can see of your profile follow these steps:

  1. From your Facebook homepage, click your name on the blue bar at the top of the page.
  2. Click the three dots next to ‘View Activity Log’.
  3. Now select ‘View as…’

Run a quick privacy checkup

To run a checkup click the question mark in the top right corner of Facebook and choose the ‘privacy checkup’. Facebook then guides you through a few steps showing what your main settings are.

From within this section think about what you really need to share. For example do people need to know the YEAR of your birth or just your birthday? You can hide the year and your friends will still get the notification.

Edit advanced privacy

While the above checkup covers the most obvious information you can delve much deeper via the privacy section. Click the V-shaped drop down to the right of the question mark and go to settings and select privacy.

Adjust timeline and tagging

In the privacy settings (mentioned above), you can control who can tag you, who can see or share the tagged content and what shows up in your news feed.

I hope that explains about privacy and allows you to go in  and change the settings to what you want and not what the Facebook defaults are.

Tightening your Facebook privacy only takes a few minutes, but it can save you a whole lot of trouble in the future. If you need help with this, just give us a call on 08 8326 4364 or via email at support@dpcomputing.com.au.
