Cybersecurity threats can affect businesses of any size, and the warning signs are not always easy to recognize. An employee might receive an unusual login notification, notice that a computer is running slowly or find an unexpected email in their sent folder. While these issues do not always indicate a cyberattack, they can be early signs of a security problem that requires attention.
Small businesses often rely on email, cloud applications and connected devices to manage their daily operations. A compromised account or infected computer can interrupt business activities and expose sensitive information. Knowing what to watch for can help employees recognize suspicious activity and report potential problems before they escalate.
Here are seven warning signs that your business may have a cybersecurity problem.
1. Unexpected Login Notifications
Employees should pay attention to login alerts they do not recognize, especially those associated with unfamiliar devices or locations. An unexpected multifactor authentication request may indicate that someone is attempting to access an account.
Employees should never approve a login request they did not initiate. Instead, they should report the notification to their IT provider and have the account reviewed for suspicious activity.
2. Computers Suddenly Running Slowly
A computer that suddenly becomes unusually slow, freezes frequently or crashes without explanation may have a malware infection. Malicious software can consume system resources and interfere with normal operations.
Performance problems can also result from outdated software, hardware issues or insufficient storage. However, persistent or unexplained changes should be investigated, particularly when several employees experience similar problems.
3. Emails You Didn’t Send
A compromised business email account can give cybercriminals access to customer information, internal communications and financial records.
Employees should report unexpected messages in their sent folders, unfamiliar email forwarding rules or complaints from customers about suspicious messages. These activities may indicate that an unauthorized person has gained access to an account.
Business email security is especially important because criminals may use compromised accounts to impersonate employees and request payments or sensitive information.
4. Unusual Pop-Ups or Unexpected Software
Unexpected advertisements, unfamiliar browser extensions and software that employees do not remember installing can indicate a potential security problem.
Some malicious programs disguise themselves as legitimate applications. Others generate fake security warnings designed to persuade users to download additional software or provide payment information.
Employees should avoid clicking suspicious pop-ups and contact their IT provider before attempting to remove unfamiliar programs.
5. Files That Suddenly Become Inaccessible
Employees who cannot open familiar documents or notice that file names have changed should report the problem immediately. Although these issues can result from technical errors, they can also indicate ransomware.
Ransomware is malicious software that can encrypt business files and prevent employees from accessing important information. Cybercriminals may demand payment in exchange for restoring access and sometimes threaten to release stolen data.
6. Unexplained Password Changes or Account Lockouts
An employee who suddenly loses access to an account should investigate the problem, especially if they receive notifications about password changes they did not request. Unauthorized password resets, unfamiliar account recovery information and repeated login failures can indicate that someone is attempting to gain access to business systems.
Businesses should use strong, unique passwords and multifactor authentication to protect their accounts. Employees should also report unexpected account changes rather than repeatedly attempting to log in.
7. Unusual Financial Requests or Changes to Payment Information
Not every cybersecurity problem begins with a computer malfunction. Some attacks involve criminals impersonating business owners, employees, vendors or customers. An employee might receive an unexpected request to transfer money, update a vendor’s banking information or send confidential financial documents. These requests can arrive through legitimate email accounts that criminals have compromised.
The FBI recommends verifying payment changes through a separate communication channel, such as calling the vendor using a previously established telephone number. Businesses should establish clear procedures for approving financial transactions and encourage employees to question unusual requests, even when they appear to come from someone they know.
What Should Your Business Do If You Notice These Warning Signs?
Recognizing suspicious activity is only the first step. Employees need to know how to respond when something appears wrong. Business owners should encourage employees to report unusual activity immediately rather than attempting to investigate or resolve potential security incidents themselves. An IT professional can review affected accounts and devices, determine whether a security breach has occurred and recommend the appropriate response.
Regular software updates, secure data backups, employee cybersecurity training and multifactor authentication can also help businesses reduce their exposure to cyber threats.
