How to Handle Phishing Attacks
Phishing attacks primarily target your employees with emails and websites that trick people into downloading malware. For example, a hacker might send someone an official-looking email with instructions to open the attachment, fill out the form, and return it. When your employee opens “the form,” malware gets installed on the computer and starts to spread throughout your network. You can lower the risk of phishing attacks by training your employees to spot suspicious emails and websites. Unfortunately, prevention doesn’t always work. When you believe a phishing attack has targeted your system, you need to know how to handle the situation. This article will discuss how to handle phishing attacks at your business.
Know the Common Signs of a Phishing Attack
Employees may never know that they installed malware on your computer system. More often than not, though, the malware that a phishing attack installs will create some common symptoms. Look for odd behavior such as:
- An increase in pop-up ads.
- Slower speeds than usual.
- Browsers navigating to suspicious websites.
- Unexplainable increases in network processing, especially during slow times of the day.
- Functions and apps stop working.
- Lost connections to networks and services.
- Reports from people who say they’ve received spam from your company’s email addresses or social media accounts.
The symptoms will differ depending on the type of malware that infects your network. You should investigate any of these signs to keep your system safe.
Search Your System for Abnormalities
You can often pinpoint malware from a phishing attack by searching your system for abnormalities. For example, you may find an application that no one in the IT department authorized. You could discover that your server processes more information than usual (typically a sign that criminals have hijacked your server to mine cryptocurrencies).
Observe your system for anything that looks out of the ordinary. Even one odd file could help you determine what type of malware has infected your system.
Find the Right Cybersecurity Tool to Remove Malware
You may need to download a specific tool to remove malware from your system. Some malware uses sophisticated defenses to block detection and uninstallation. The cybersecurity tool that you used to remove malware last month might not work this time.
Ideally, you can scan your system to determine what piece of malware you have. Then, you can find the correct tool to delete it permanently. You will probably need to reboot your system several times during this process. You may also need to execute the removal tool within Safe Mode to prevent the malware from defending itself.
Identify the Phishing Attack’s Source
Phishing attacks can do tremendous damage to your company, so you should try to identify the source of the attack. If your IT team doesn’t have the skills to identify the phishing attack’s source, you can get help from CPI Solutions.
Once you know the source of the recent attack, you can plan a response to future attacks. You might decide to train your employees to recognize phishing schemes, choose a cloud service provider with better security, or a different step that applies to your specific situation.
