PDF and Excel Spam
I do not know how it feels when a PDF spam is attacked, but my friend has ever told me that when he opened email and got bombarded with several suspicious PDF attachments. To me, it is so easy to handle PDF spam, usually I will just delete the email without ever having to so much as see the contents.
I have tried to search many information about PDF scam recently, perhaps you might not know that beginning to take image spam’s place is PDF spam, where the spammer sends an email with the PDF attachment in which most spam filters can’t read at all - that attempts to convince the recipient to purchase stocks.
The battle between spammers and spam-filter vendors will always be a game of cat and mouse. The better the tools the more creative spammers will be. After anti-spam software vendors came out with updates and filters that analyzed the body of every PDF file, then spammers took less than a month to come out with new option: Microsoft Excel files for push-and-dump scams.
No matter how creative the spammers will be, I believe that there will be a solution to overcome it. For example, GFI MailEssentials offers anti-spam for Exchange server and other email servers and eliminates the need to install and update anti-spam software on each desktop. It can eliminates over 98% of the spam in your network, including PDF and Excel spam, as well as detect and block phishing emails and hard-to-catch image spam through a Botnet/Zombie check.
I know my previous company didn’t install anti-spam software in the server, I hope after my previous colleagues read this post, hopefully they will suggest their boss to use GFI MailEssentials software because many of them didn’t care about the spam email, they will simply open the attachment and read it. I was thinking that GFI MailEssentials software is necessary for them.
