Small and medium-sized businesses (SMBs) are increasingly being targeted by cybercriminals, and two of the most common tactics used are phishing and ransomware. But, with limited resources, how can SMBs make sure they remain safe?
In this easy-to-understand phishing and ransomware guide, we’ll explain what these threats are, how they work, why they’re especially dangerous, and the best SMB cyber security protocols to ensure safety.
What Are Phishing and Ransomware?
Phishing is a form of scamming that tricks you or your team into clicking a malicious link, downloading a harmful attachment, or handing over sensitive information. These scams often pose as a trusted contact, like a bank, supplier, or colleague.
Meanwhile, ransomware is a type of malware that infects your systems, encrypts your data, and demands a ransom payment to unlock it. In many cases, even paying the ransom doesn’t guarantee your data will be returned.
So, why are phishing attacks and ransomware such a big issue for SMBs? This answer is simple. Smaller businesses often lack a dedicated IT team and cyber security strategies to spot and stop these threats. This makes them a prime target for cybercriminals to easily exploit.
How Phishing Attacks Work
Phishing often starts with an email that looks legitimate but contains something dangerous. It might ask your staff to “verify an invoice”, “confirm login details”, or “click to view a delivery notice”.
An example of larger-scale phishing is the 2020 Twitter VIP Attack, which compromised 130 high-profile accounts belonging to celebrities, politicians, and business leaders.
These compromised accounts were used to tweet fraudulent messages and trick unsuspecting followers into sending Bitcoin. The scammers were able to amass over $100,000 in Bitcoin before it was shut down.
This incident is a strong reminder of the sophisticated attacks that criminals can successfully carry out. The successful Twitter attack prompts questions into the security protocols that major social media platforms have in place to protect their users.
Top 4 Common Phishing Tactics
- Spoofed email addresses that resemble legitimate ones
- Urgent or threatening language (“Your account will be locked!”)
- Unexpected attachments or links
- Requests for sensitive information like passwords or payment details
How Ransomware Attacks Work
Ransomware usually gets into your system through a phishing email or by exploiting outdated software. Once it’s in, it locks you out of your own files and systems by encrypting everything. Then, a ransom note appears, demanding payment, often in cryptocurrency.
However, businesses must decide between paying the ransom and only getting back partial access to their data or rejecting the payment and accepting permanent data loss.
Paying a ransom doesn’t guarantee everything will automatically go back to normal. A prediction by Cybersecurity Ventures estimates that the global cost of cybercrime will reach $276 billion by 2031, up from $57 billion in 2025.
With businesses not only facing the ransom payment but also losses from downtime, recovery expenses, and reputation damage, the cost of ransomware quickly becomes unaffordable for many.
What Are the Warning Signs of Phishing and Ransomware Attacks?
It’s crucial to spot the early signs of phishing and ransomware to ensure your business remains protected. Let’s look at the signs you and your team should look out for:
For phishing, keep an eye out for any unfamiliar or slightly altered email addresses. This is often just one letter off from the real thing. Additionally:
- Phishing emails may contain poor grammar or spelling mistakes.
- They will try to create a sense of urgency, like warning you that your account will be locked unless you act now.
- You might also notice the link in the message doesn’t match the official website it claims to be from.
- The message may claim to be from a colleague or supplier requesting something unusual, like an unexpected payment or login details.
For ransomware, you may suddenly lose access to files or systems, with your data becoming encrypted and a ransom note appearing on screen. Other indicators include:
- A noticeable slowdown in computer performance.
- Software behaving strangely.
- Antivirus protection being disabled without explanation.
4 Ways SMBs Can Protect Themselves
- Use Multi-Factor Authentication (MFA): Add an extra layer of protection to logins. Even if a password is stolen, MFA can stop unauthorised access.
- Keep Software and Systems Updated: Outdated systems are a common entry point for ransomware. Always install patches and updates as soon as they’re available.
- Educate Employees: Cyber security training helps staff spot phishing attempts and handle emails and links with caution.
- Back Up Your Data: Regularly back up important files and test your ability to recover them to make sure they can keep your data safe in a ransomware attack.
