This is a security attempt aimed to completely halt hackers and prevent them from sending malicious contents or files capable of transferring viruses and malwares. As a result, Gmail will put a ban on sending such attachments that contains Js file extension starting from the 13th of February, 2017. Google made this known, through a post on GSuite official blog.
The GSuite Blog update reads – “Gmail currently restricts certain file attachments (e.g. .exe, .msc, and .bat) for security reasons, and starting on February 13, 2017, we will not allow .js file attachments as well. Similar to other restricted file attachments, you will not be able to attach a .js file and an in-product warning will appear, explaining the reason why.”
Furtherly, – “For inbound mail, senders will get a bounce message explaining why the email was blocked.”
Google however made it known that “If you still need to send .js files for legitimate reasons, you can use Google Drive, Google Cloud Storage, or other storage solutions to share or send your files.”
Owing to the fact that some of these attachments and files are capable of being used to execute attacks on cybers, google decided to prevent them from being sent over gmail. In addition to the Js files, other file extensions also to be banned include ADE, .ADP, .BAT, .CHM, .CMD, .COM, .CPL, .EXE, .HTA, .INS, .ISP, .JAR, .JSE, .LIB, .LNK, .MDE, .MSC, .MSP, .MST, .PIF, .SCR, .SCT, .SHB, .SYS, .VB, .VBE, .VBS, .VXD, .WSC, .WSF,.
These have been used to send harmful codes in emails, and as soon as the user opens his or her mail, the code resumes operation enabling the hacker to tamper with the user’s account.
Remember, despite the banning, the good news remains that users can still use Google Drive, Google Cloud Storage and other such solutions to share or send files for good and healthy reasons.
