  "body_md": "Have you ever tried opening an 'encrypted' email or important document, only to discover a suspicious extension like .docx.exe instead of the expected .docx? Or received an attachment supposedly containing a bill, contract, or memo that turned out to be something entirely different? In many cases, this signals a malicious attempt to infect your device.

Cybercriminals frequently disguise malware as seemingly harmless documents or archives, relying on users overlooking file extensions. Kaspersky Lab researchers have identified the most commonly used malicious file types in harmful email campaigns. Here's what these extensions really mean and how attackers use them—often by exploiting hidden dangers in familiar-looking files.

While some of these extensions are legitimate for everyday tasks (e.g., .exe for Windows programs), they become dangerous when misused in attacks. We examine the top 15 extensions found in malicious email attachments and explain their real-world risks. By understanding these threats, you can better protect yourself from falling into cybercriminal traps."
