Email Attachments

Given we, as a society, rely on emails more so now than we have ever done in the past, it should not come as any kind of surprise that there are people out there who intend to capitalise on that reliance by sending dangerous emails. Malware is spread most commonly via emails and due to the fact businesses use them very frequently, it’s no surprise that many organisations opt for the help of IT Support to ensure if any harmful software is downloaded, it can be effectively dealt with. So, what are some of the dangerous email attachments that your business should be on the lookout for?

ISO Files

In everyday life, people tend to use ISO files to create a handy copy of items on a physical disc or some kind of memory stick, and they are used in order to distribute operating systems. Of course, a more harmful use of ISO files is that they can also be used as a means to distribute malware. Despite the fact these files are used legitimately every day, there really isn’t any reason that anybody should be sending you an ISO file. Therefore, as a rule, if you see this attachment then immediately bin the email.

EXE Files

Again, these are common files that you are likely going to see when you are installing software from the internet. The same rules as previously stated apply when it comes to these attachments in emails, which is that there isn’t a good reason why anyone would send you one and if they have, it most likely contains malware. As such, if you get any unsolicited emails with an EXE file, give it a miss.

 Compressed Files

Compressed files are a lot trickier when it comes to working out if there is malware contained in them because there are very good reasons as to why people would legitimately send you a compressed file in an email (they make files smaller). They are great forms of camouflage for malware because they disguise what is actually in the attachment (for example, it could simply be another ISO or EXE file) and as such those favoured by online threats. Unless you can be absolutely 100% sure that someone has sent over a compressed file for a legitimate reason and you are expecting it, you shouldn’t click on them. It may be worth your business getting an account with someone such as Dropbox or WeTransfer in the future as these are much more secure options when it comes to sharing large files.
