Here's one way for you to use your noodle before clicking on attachments. Check out our Tech Tuesday blog for more info!
A common way that bad guys sneak malware onto your computer is through macro-enabled Excel files. A macro (short for macroinstruction) is a set of commands that automate a process in Excel. When you open an Excel file that includes macros, you’ll see a security banner with the option to activate macros by clicking “Enable Content”. Typically, malicious Excel files are attached to a phishing email. If you choose to open the attachment and enable macros, the file will automatically install the cybercriminal’s malware.
In a recent phishing attack, the macro-enabled Excel attachment is designed to look like a Windows Defender help page. The spoofed help page provides easy-to-follow instructions on how to click the “Enable Content” button. To establish additional credibility, the file includes logos of well-known security vendors like McAfee. If you fall for this trick and enable macros, a dangerous piece of malware is installed onto your computer and cybercriminals will have complete access to your system.
