Malware and phishing attacks are on the rise – Here’s how you can protect yourself
16 June 2017
Phishing is a form of online identity theft, or the introduction of damaging viruses and other software into a business. The aim is to steal information or make IT systems unusable until a ransom is paid.
Phishing is certainly on the rise again, helped by malware and virus tool kits that are simple to download and chance – even by inexperienced “hackers”. It is a global business and worth the effort, it’s all about the money now.
Even though businesses have security systems in place it’s not unlikely that something will slip through the net at some point in time. When this happens the last bastion of defence is the IT users. When phishing attacks are successful it’s usually down to an untrained member of staff clicking on a link or opening an attachment, so it’s critical that employees fully understand the basics.
Security basics for phishing attacks
So, what areas should businesses be making their employees aware of to protect the business from phishing attacks, either on a website or via SPAM?
1. Protect against SPAM – Users must be educated in terms of what to look for, such as:
- Comes from unrecognised senders – always check the email address, even if the name is familiar
- Asks you to input personal information – especially if it’s required urgently
- Aren’t personalised
- Try to make you act quickly – often by frightening or threatening you into action
2. Use a phone or secure websites to enter information – When asked to enter personal information check the status bar of your web browser for a lock icon, or check the web address in the bar starts with https://. Also check the domain to check that it’s right i.e. no spelling mistakes or unnecessary hyphens.
3. Be wary of links and downloads – When opening web pages or emails you should only really be opening attachments or downloads when you are expecting them, even if you know the sender.
4. Don’t send sensitive information via email – Email is quite a simple technology and is often targeted during attacks. You just don’t know who could gain access to your emails, either in your mailbox, whilst travelling over the internet, or in the recipients inbox.
5. Watch out when links within emails ask for personal information – The best way to get a target to enter sensitive information is to send an email that look exactly like an email, say, a bank or company like Amazon would send to their customers. It’s very unlikely that these organisations would ask for sensitive information from within an email so pick up the phone and call the company and check.
6. Pop-ups usually mean danger – It’s extremely unlikely that a legitimate organisation will use pop-up windows
- Never enter any personal information into a pop-up window
- Do not click links in a pop up
7. Have multiple layers of security – Ensure that you have the basics in place, such as:
- SPAM filters
- Firewalls with zero-day threat protection
- Anti-virus and anti-malware software on your servers, laptops and other devices
8. Think when you receive a phone call – It’s now becoming more common for attackers to call their target, often pretending to be from the IT team or the bank. They then direct you to a website that will then steal your information or allow them to access your machine. Always be wary of callers, call them back if necessary.
Staff should walsy be careful when entering sensitive information, clicking links or opening attachments and downloads they aren’t expecting. If you train them in what to look for, your chances of a security breach are drastically reduced. As stated before, the majority of attacks are now targeting the end users and, at times, can breach defenses – even at large firms.
