It also exploits weaknesses in a website’s coding – or into applications – but it injects code that can alter or add scripts. And if you enable any kind of transactions on your website, this could be extremely damaging.Ī similar attack is cross-site scripting, or XSS. If you save logins, email addresses or any kind of personally identifiable data that’s accessible by your website, your customers and your business could be at risk. The code gives the hacker access and control to the web server’s database to make changes and steal data as they please. SQL is used to read that search, or query, and return relevant results from a database stored on the web server.ĭuring an SQL injection attack, weaknesses in a website’s development are used to upload, or inject, malicious code into the database. For example, if you want to know the local branch of a retailer, you might visit their website and type the location into a search bar. SQL, or ‘Structured Query Language’, basically refers to the language used in database management. But we’re betting that not so many will have heard of SQL injection. The average employee may have heard the terms ‘malware’ or ‘phishing’, even if they don’t know what it means. While phishing emails are sent en-masse, spearphishing is highly targeted. For example, they might set up a replica account for the CEO and email an assistant to send bank login details. Assailants will spend time researching a company or individual and identifying who they should imitate and who they should target to get the best chance of success. Phishing, on the other hand, are emails that appear to be legitimate and from a trusted source, like a bank or charity.
Spam simply means unwanted emails, or junk mail, and most well-known email providers are good at filtering out what they think you won’t be interested in. Phishing emails, or phish, are sometimes referred to as spam, but they are not the same.
However, they are now far more sophisticated and can be used to steal information such as credit card details using techniques such as phishing.

This is why anti-malware is an important part of business security it stops malicious software before it reaches your device.Įmail attacks used to be fairly easy to spot – an email with poorly written language and an over-dramatic sense of urgency asking you to click a strange-looking link or send some money. Most of the time, you won’t know that malware is attacking your network until it has already wreaked havoc you may wonder why your device seems slower than usual, or why your memory is suddenly full. You may think you are downloading a harmless app to your computer or mobile, while in fact, you are allowing a virus to access your device. A Trojan is – as you may expect if you know the classic tale of subterfuge from Ancient Greece – malware disguised as legitimate software. Malware can enter your system in many ways, including through email or via a shared connection with a device that’s already infected. The cybercriminal will then block your access to those files and demand that a ransom be paid in exchange for the safe return of your data (of course, payment is no guarantee that your data will actually be returned). Ransomware is a type of malware that gives a hacker access to your files. There are many types of malware and we expect that even businesses with limited security knowledge will have heard of one the most well-known: ransomware. Malware, or malicious software, gets access to your device without your knowledge to cause general mayhem: giving bad actors access to your files, using your device as a base to spread viruses across a network, generating revenue for the developer, stealing login details, and so on.
