There are several characteristics that can help identify suspicious attachments:
File Type: Executable files (.exe, .bat), scripts (.js, .vbs), and certain document types (.docm, .xlsm) are often used to spread malware. Unsolicited Attachments: Attachments from unknown or unexpected sources should be treated with caution. File Size: Unusually large files can be a red flag. Suspicious Content: Attachments with vague or suspicious names and content should be avoided.
