Malicious links disguised as legitimate emails, viruses, and malware hidden behind seemingly safe software, and stolen passwords used to access sensitive information – these are just some of the ways hackers can compromise small businesses. Cyber attacks on small businesses have become increasingly common in recent years, with attackers taking advantage of weak security measures and a lack of resources devoted to protecting against them. Here’s why you want to think about hiring a cyber consultant to save you from the consequences of cyber attacks.
Data Loss
A successful cyber attack can result in a range of different types of data loss. Customer information and financial data can be stolen, leading to significant financial losses. For example, attackers may use stolen credit card numbers to purchase products and services. Intellectual property such as patents and trademarks could also be lost, affecting a business’s bottom line. For example, a malicious hacker could take the source code of a business’s software, reverse engineer it and resell it as their own product.
Lawsuit Risks
Businesses, even small ones, can be held liable for the damages caused by a cyber attack and may face legal action from customers or other companies.
As per data protection laws, businesses must take reasonable steps to protect their customer’s confidential data and could be fined for failing to do so. Companies may also face class-action lawsuits, as customers may sue if their personal information is exposed or stolen. To illustrate, say a holistic medical center is hacked and patient records are stolen – the patients could sue for damages.
Businesses may even be sued by other companies if their data has been used to commit fraud or damage the other company’s brand image. Read more about Can You Map Out Bad Data?
Reputational Damage
Cyber attacks can also have a damaging effect on brand reputation. Customers are likely to become wary of using a business if they know it has been hacked. As such a breach is negative publicity for the company it could cause customers to switch to competitors.
Say a gift shop is hacked and customers’ personal information is stolen. It’s likely that customers will be less inclined to shop at the store, as they may not trust it enough to share not just their payment details, but loved ones’ addresses.
Operational Disruption
The direct effects of a cyber attack, such as data theft or manipulation, can have a detrimental effect on the day-to-day operations of a small business. If hackers are able to access customer records or financial information, for instance, it could take weeks or even months for businesses to restore and secure this data and get it back up and running.
Businesses may even have to invest in new systems altogether, further halting operations.
Cyber attacks can have a devastating effect on small businesses and the consequences can be long-lasting. Businesses need to consider investing in cyber security measures such as hiring a consultant or implementing appropriate staff training to help protect against these threats.
Common Types of Cyber Attacks on Small Businesses
| Attack | How It Works |
|---|---|
| Phishing | Fake emails trick staff into sharing passwords or clicking bad links |
| Ransomware | Malware locks your files until you pay a ransom |
| Malware | Harmful software that steals data or damages systems |
| Business email compromise | Attackers pose as a boss or supplier to trick staff into sending money |
Phishing is the most common attack on small businesses. The US Cybersecurity and Infrastructure Security Agency (CISA) says phishing is often the first step in a larger attack. Train staff to check the sender before they click a link or open a file.
What to Do After a Cyber Attack
If you are attacked, act fast. First, disconnect the affected systems from the network to stop the spread. Second, change passwords for key accounts. Third, report the attack. In the US, report to the FBI Internet Crime Complaint Center (IC3) at ic3.gov. Fourth, tell affected customers what happened and what data was exposed. Fifth, restore data from backups. Do not pay a ransom if you can avoid it, as paying does not guarantee your files will be returned.
Basic Protection for Small Businesses
Turn on multi-factor authentication (MFA) for all accounts. MFA asks for a second proof of identity, such as a code from a phone app. Keep software updated, as updates fix security holes. Back up data with the 3-2-1 rule: three copies, on two different types of storage, with one copy off-site. Train staff once a year on phishing and password safety. Limit access so staff can only reach the data they need for their job.
Should You Get Cyber Insurance?
Cyber insurance can help pay for the costs of a breach, such as legal fees, customer notices, and data recovery. It does not prevent attacks. Check what the policy covers and what it excludes. Many insurers now ask for MFA and backups before they offer a policy. Compare quotes and read the terms before you buy.
Frequently Asked Questions
What is the most common cyber attack on small businesses?
Phishing is the most common attack. Fake emails trick staff into sharing passwords or clicking bad links. CISA says phishing is often the first step in a larger attack.
What should I do first after a cyber attack?
Disconnect the affected systems from the network to stop the spread. Then change passwords for key accounts and report the attack.
Should I pay a ransom after a ransomware attack?
Try not to pay. Paying does not guarantee your files will be returned. Restore data from backups and report the attack to the FBI IC3.
What is multi-factor authentication?
It is a second proof of identity, such as a code from a phone app, in addition to a password. Turn it on for all accounts.
What is the 3-2-1 backup rule?
Keep three copies of your data, on two different types of storage, with one copy off-site. This protects you if one copy is lost or locked.
