For all the convenience the internet provides, it’s also a very dangerous place. If you’re not actively protecting yourself and your data, you’re leaving your business open to many types of cyber-attack, such as social engineering, cross-site scripting, and injection attacks – more than 80% of UK organisations experienced at least one successful cyber-attack in 2020/2021. Cyber-attacks are constantly evolving – we’ve seen the advent of eavesdropping attacks and man-in-the-middle attacks over the years – but you should at least be aware of the most common types that can potentially target your business.
Types of cyber-attacks – Email attachments, cyber threats, and malicious activities
1. Malware is the root of most cyber-attacks
Malware is short for malicious software – it is harmful software that is designed to disrupt, disable, or take control of your computer system. Malware comes in many forms, and there are many types of malware, usually hidden away in a file or disguised as a harmless app. It works by taking advantage of technical flaws or vulnerabilities in your hardware and software. For most malware attacks to work, they require a key ingredient – people. Cyber-attackers find ways to trick people into running a malicious file, opening an infected file, or clicking an unsafe web link. Antivirus software can be one remedy for this.
2. Encrypting files, demanding a ransom, and network vulnerability
A ransomware attack is one of the most dangerous forms of malware today. This type of attack threatens to publish the victim’s data, or completely block access to it, unless a ransom is paid. Ransomware has increased in usage because more businesses are willing to pay a ransom to get their data back. In 2020, 13% of all UK businesses who suffered this type of attack reportedly paid the ransom.
3. Don’t fall for the bait – malicious email attachment, suspicious activity, and legitimate requests
Phishing – as the name suggests, like a fisherman dropping bait into the water, phishing attacks try to lure unsuspecting people into revealing personal information. This is where a line is set out into an unsuspecting user’s email inbox and then somebody grabs that fishing line and it drags them in intended to deceive that person into perhaps clicking on a malicious link or following certain instructions that may appear to have come from a legitimate source. Reports have found that May 2021 was a record month, with a 440% increase representing the largest spike in phishing attacks in a single month.
All phishing attacks have something in common, they exploit human nature rather than technology. Many phishing emails trigger your emotions by telling you something is wrong, or that bad things will happen if you don’t respond. Phishing emails often want you to act with urgency, and most phishing emails try to build trust by impersonating a brand or person you know.
Overloading the system, SQL injection explained, and other cyber security threats
4. DoS (Denial of Service Attack) targets the website or the backend database, flooding it with fake traffic, resulting in a website crash. A more sophisticated attack is a DDos (distributed denial of service) attack, which sends traffic not from one single source but from multiple sources all at the same time, in the hope of overloading the system.
5. SQL injections are one of the common cyber-risks, in part because of how simple it is to perform. SQL injection involves using code to hack databases and steal information. SQL stands for structured query language, which is a type of computer language used to pass information across databases. This type of attack injects malicious code into databases to retrieve sensitive customer data, and is very commonly done on login screens.
6. The strength of passwords matter, as does cyber-security controls
Password attack – for hackers, cracking passwords is one of the easiest ways to hack a system, as no prior knowledge about the victim is needed to start an attack. There is a risk of hackers easily gaining full user access and causing a data breach, impacting not only business owners, but also customers that may have logins to the business’ website. Attackers let the computer do the work, by trying different combinations of usernames, default passwords, and common passwords until they find the one that works (known as password guessing). Due to this repeated trial and error format, the strength of password matters a great deal.
7. Insider threats
Your business can be attacked from within – security threats are everywhere, and you may have internal security flaws. Here the hacker gains access to the information path between the user’s device and the website server. By doing so, the communication line between the user and the website is secretly obstructed. This commonly happens with unsecured WiFi network connections. These attackers know how the business’ system is configured and know its weaknesses. Security measures and constant monitoring are key for business safety.
