Spam rate falls below 50 per cent for first time in a decade

Large spamming botnets are harder to run these days

Spam has fallen to less than 50 percent of all email for the first time in a decade, Symantec said.

Spam has fallen to less than 50 percent of all email for the first time in a decade, Symantec said.

Spam fell to less than 50 per cent of all email in June, the lowest in a decade, Symantec said in its latest Intelligence Report.

The levels of spam have been slowly falling since 2010 for multiple reasons. Network providers are more tuned into the problem and take action faster when there are issues on their services.

Also, unlike six or seven years ago, sending billions of messages per day from massive botnets isn't as feasible anymore.

Law enforcement, along with companies including Microsoft, have aggressively gone after some of the largest botnets over the last few years and worked to technically shut them down. Although some botnet operators have been able in some instances to regain control, the increased attention makes it more difficult for them to work.

Improved filtering and blocking also means that fewer unsolicited marketing messages reach inboxes where people might click on a message to buy a product. Response rates to spam are notoriously low, so it means spammers must reach many inboxes in order to build a business.

That's not to say spam is going to completely stop, but as the cost of entry into the spam business rises and the likelihood of a return falls, it's less of an incentive.

In June, Symantec saw 704 billion email messages sent. Of those, 353 billion were classified as spam. At one of the peaks of the spam epidemic in June 2009, 5.7 trillion of the 6.3 trillion messages sent were spam, according to past data from Symantec.

Symantec noted that phishing and email-based malware fell in June, which is evidence that "attackers are simply moving to other areas of the threat landscape."

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
