Cyber Security: Know Your Threats (Part II)

We’re following on from our cybersecurity threat blog with a second instalment – getting our readers up-to-speed with the types of attacks that could compromise their system.

Here, we dissect a mixture of long-existing and newly-emerging threats to help keep you (and your business) fully protected.

Sophisticated Phishing

Traditional phishing encouraged readers to click to claim a prize, but scammers have become far more sophisticated ever since we got used to the idea of digital deception.

Modern phishing is so fiendish, you won’t think twice about clicking the attachments that ultimately infect your system. These threats masquerade as messages from people in your contact list and forge fake invoice templates that are almost identical to the real thing.

Always think twice about downloading any accompanying files or following links – even if they’re ostensibly from someone you know. Check the email address for legitimacy and compare any bill/invoice templates to authentic examples. Contact the supposed sender through other means if you spot something that feels off (slightly skewed logo, unauthorised purchase, aggressive language emphasising the importance of clicking a link) and invest in effective mailbox security from Focus to stop receiving related threats in the future.


Worms are designed to replicate themselves and spread as far through your system (and any systems you might be connected to) as possible. Some strains are far more dangerous than others and can force your system to grind to a halt.

Often given an open door via email downloads, worms will keep spreading until you take action. In some cases, they may send emails ‘from you’ to your contacts list, attempting to compromise their systems as well as yours.

Focus can perform a full system evaluation to determine the entry point of any worm, drawing on sophisticated defence techniques to halt the duplication, minimise the damage, and ultimately eliminate the problem once and for all.


Distributed denial-of-service attacks were flagged as a major threat to look out for at the start of 2017, and are expected to remain prevalent moving forwards.

Websites can experience downtime when too many users attempt to gain access to the domain at once, and DDoS attacks involve deliberately rerouting traffic to force a crash. When a website is wounded, it’s open season for cybercrooks to pinch information.

Focus can develop your defence systems so they recognise and effectively manage high levels of traffic, ensuring the integrity of your website is never undermined.

Cross-site scripting (XSS)

Cross-site scripting doesn’t just put your business at risk – it throws your customers in danger too.

These attacks tend to befall vulnerable websites with insufficient cybersecurity measures. The co-ordinator injects a code designed to run in the user’s browser, which means that anyone who accesses your site will be hit by the virus. Then, silently and surreptitiously, their personal information is swiped one piece at a time…

With strong cybersecurity measures in place, your website will be too tough to break for attackers, meaning they are forced to turn elsewhere.
