Spammers Left Behind All Computer Securities

Chief security analyst at MessageLabs, Mark Sunner, said that in the past few weeks, PDF attachment have tremendously risen up and now it is almost equal to 20% of the all image spam. PDF seems to be more trustworthy and appears strictly professional. By using the Adobe Acrobat, the attackers can easily flout the security techniques, which make it tougher for the anti-spam software to detect the contents, as per the news of itpro.co.uk on August 26, 2007.

The experts of anti-spam predicated that the face of spamming can become even worse. E-cards and PDF mail attachments surrounds the security systems and continues to annoy the customers. The latest Storm mail virus and pump and dump stock scams are knocking the inboxes and allures the users to install harmful malware, as reported by Indystar.com on August 20, 2007.

This process clearly exhibits the frequent change in spam packaging. As soon as the anti-virus offers a solution, a new technique came out. Image spam, the most commonly used spam, is starting to disappear because of the advancement in anti-spam techniques, which increases the chances of its detection.

The volume of fake e-cards, which possess the links to worms and viruses, has also increased. From mid-July onwards, Postini, the security firm, has halted 800 Million copies of Storm, a mail that puts up the mask of an e-card. Senior marketing manager at Postini, Adam Swidler, describes it as a "cat and mouse game" and PDF is the latest twist, as per the news of Indystar.com on August 20, 2007.

Hackers have started using Excel and zip files to spread viruses and spam, which has the same base as PDF spam. On top of that, owning to its authentic nature, this kind of spam has succeeded in holding greater attention.

Co founder of IronPort systems, Tom Gillis, said that since spam has emerged from text in mail to images fixed in attachments, the chances of detection has become even more lesser and tougher. He added, normally, people trusts PDF and Excel file and therefore opens it, as per the news of Indystar.com on August 20, 2007.

Further, the spammers have also tried their hands at adopting advertisements - from stocks to Viagra. The subscribers of Google's news alerts have started receiving links to these kinds of advertisements among their news links.
