You may think it is a bit of fun to type in your answers to the quiz, which asks silly questions such as your nickname and first model of car? You may think it is some plain old fun, but many of these social media questionnaires are set up by hackers to steal your identity. Continue reading

Businesses around the world are being targeted with a cyber-attack that sends victims a fake invoice that looks real enough to fool to most people. It is based on an old scam that used to see invoices faxed or mailed to the victims and now it has made its way into the digital world and instances are on the rise.
You may have already seen some of the less effective attempts – an email advising your domain is expiring (except it’s not from your host and your domain is nowhere near expiration) or others that describe a product or service you would never have purchased.
The new attacks though are much more advanced as they look completely legitimate and are often from contractors and suppliers you actually use. The logos are correct, spelling and grammar are spot on and they might even refer to actual work or products you regularly use. The senders name may also be the normal contact you deal with at that business as cyber criminals are able to ‘spoof’ real accounts and real people. While it is worrying that they know enough about your business to wear that disguise so well, a successful attack relies on you not knowing what to look for.
Here are two types of invoice attacks you may receive:
1) The Payment Redirect
This style of fake invoice either explicitly states that the payment should be made to a certain account (perhaps with a friendly note listing the new details) or includes a payment link direct to a new account. Your accounts payable person believes they are doing the right thing by resolving the invoice without bothering you and unwittingly sends money to a third party. The problem may not be discovered until an invoice from the real supplier comes in or the transaction is flagged in an audit. Due to the nature of international cyber crime, it’s unlikely you’ll be able to recover the funds even if you catch it quickly.
2) The Malware Link
Rather than an immediate cash grab, this style of attack asks your employee to click a link to download the invoice. The email may even look exactly like the ones normally generated by popular accounting tools like Quickbooks, Xero or MYOB. Once your employee has clicked the link, malware is downloaded to your systems that can trigger ransomware or data breaches. While an up-to-date anti-virus should block the attack at that stage, it’s not always guaranteed (especially with new and undiscovered malware). If it does get through, the malware quickly embeds itself deep into your systems and often remains silent until detected or activated.
How to Stay Safe
Awareness is key to ensuring these types of attacks have no impact on your business. As always, keep your anti-virus, firewalls and spam filters up to date to minimize the risk of the emails getting through in the first place.
Secondly, consider implementing a simple set of procedures regarding payments. These could include verifying account changes with a phone call (to the number you have on record, not the one in the email), double checking the invoices against purchase orders, appointing a single administrator to restrict access to accounts or even two-factor authorization for payments. Simple preemptive checks like hovering the mouse over any links before clicking and quickly making sure it looks correct can also help. If anything looks off, hold back on payment / clicking until it has been reviewed. Fake invoices attacks may be increasing, but that doesn’t mean your business will become a statistic, especially now that you know what’s going on and how you can stop them.

At last count, Facebook has clocked up over 2.7 billion users, this makes the platform more attractive than ever for scammers and hackers. While you may be logging in to share your latest family photos or catch up with friends, the chances of accidentally triggering a scam or malware are increasing every day. Here are some tips on how to stay safe on Facebook and stop the spread of scams.
Look out for freebies and surveys
Everybody loves a freebie but when you see a giveaway for vouchers from a mega-store, alarm bells should ring. ‘Complete this survey and we’ll send you a $50 Amazon Voucher!’ – is too good to be true. Even one click can take you on a messy journey through the underbelly of the web, picking up trackers and malware at every step and then you are asked to share the post so your friends can get a voucher too…except nobody ever receives the reward. So stop it at the start and never click on these scam offers.
Check your permissions with games and quizzes
Whenever you access a new game or quiz, you’ll need to give it permissions to access your Facebook profile. Most people click the okay button without any thought, but if you review the permissions you are giving, you will often find they are asking for a massive amount of unneeded personal data; this data can include your public profile, friend list, email address, birthday and newsfeed. Do they really need access to ALL this information? Sometimes the shakedown is from necessity, but sometimes the apps are preparing to launch attacks against you both on and off Facebook. For example, when you call your financial institution bank they ask certain questions like your full name, birthday and maybe which high school you went to. All that information is in your Facebook profile and now shared with your permission to an unknown entity.
Don’t friend people you don’t know
Having lots of friends is always nice, but that friend accept may end up costing you. It might be someone pretending to know you, or a picture of a pretty girl to entice men (and vice versa). Once you friend them, they will get access to everything your friends can see. In this case, it’s more than the risk of someone knowing your personal data, you’ve just given them access to intimate details of your life. It’s exactly how romance scams start, and there are even cases where the victim finds photos of their children circulating the internet.
If it is weird, forget it
It doesn’t happen very often, but hackers find ways to take advantage of flaws in Facebook. A common hack that keeps popping up in various forms is to embed malware in a link. The virus then infects your machine and contacts all your friends with an enticing message, like asking whether a picture is of them. When they click to view the picture, the virus catches them and their friend list, and keeps on spreading. Facebook is pretty good at staying on top of these flaws, but they need time to fix it. Just like if you got a weird email with an attachment from a friend, use that same level of scrutiny in your Facebook and don’t open messages or links that seem out of place.
