What is a Macros virus?
A macro, fundamentally, is an action or set of actions that can be run repeatedly. It is widely used in Microsoft applications, such as Excel and Word to record mouse clicks and keystrokes to help automate tasks. Hackers convert macros into viruses by embedding malicious scripts that can harm your system.
Can macros be used to hack people?
Yes. Macros are being used by hacker’s globally to break into systems by baiting humans, as they are the weakest security link.
How do hackers exploit macros to infect your system?
Hackers create documents using the macro function in Microsoft documents, such as Excel and Word. They embed it with malicious code/script and send it to people in various organizations by creating email addresses that mimic internal email addresses. When the recipient gets an email and tries to open the document, it prompts an option to ‘Enable Macro’. If the user thinks the source is trust-worthy and enables the macro, the embedded script which was hidden in the file downloads an open source virus from the internet. It then infects the user’s system with that virus.
Why are macro based virus attacks on the rise?
We have entered the era of automation. People are automating mundane tasks to save time. Most organisations have internal files that are used to track daily activities. Macros help them complete the work faster. Hackers use this as an opportunity to exploit people that are not educated about security.
Why does your anti-malware not detect macro-based viruses?
Macros are a legitimate functionality in Microsoft documents. This means that it is difficult for an anti-virus software to detect it accurately. In a recent security breach, Macros were used to infect the impenetrable Mac OS systems. After an audit, it was found that only 4 Anti-Virus(AV) engines were able to flag it as a malicious.
