Malicious Spam Spikes To 'Epic' Level

Trailrunner7 writes "There has been a huge spike in spam volume in the last few days, including a massive amount of malicious spam with infected attachments, and researchers say that levels of junk mail are now far higher than they were before the takedown of the notorious Spamit affiliate program last fall. The huge spike comes at a time when spam should, in fact, be dropping because of the takedown of the Rustock botnet, the Spamit network and other botnets. 'From the beginning of August, we have observed a huge surge of malicious spam which far exceeds anything we have seen over the past two years, including prior to the SpamIt takedown last October. The majority of the malicious spam comes from the Cutwail botnet, although Festi and Asprox are among the other contributors,' M86 researcher Rodel Mendrez said."

not according to my graphs

my graphs show a steady decline in spam capture rates since October, 2010. we're measuring an average daily rate about 1/2 of this time last year. (millions of mail boxes, dozens of MX servers, decent antispam filtering) We're blocking around %91.2 of mail at the perimeter as opposed to %98.8 last year.

you are correct, the missing data point is the volume of email considered "not spam".  This line in the graph stayed the same over the range, or within a minor fraction of a percent of the same. it's the spam counts that have dropped since 10/2010. The customer base also represents a large number of domain names, hundreds of thousands of domain names. One of our largest customers has been offering email since 1995, with many accounts in their domain being around for over a decade. I think it's a pretty solid sample of email accounts.

Obvious

Apparently, most of the current spam is aimed at building new botnets. Which is sort of what you'd expect after a lot of botnets are taken down.

correction in the summary:

A security company with 11 products designed to solve your spam problem, has made a picture showing a bombastic and ludicrous increase in spam the likes of which you cannot possibly cope with. This spam targets your genitals using african money laundering transfers to smuggle a dirty bomb into your new nike jordans and boochi bags at 80% discount, and free shipping.

It is imperative you believe this un-renound seldom-published security engineer working for a vague corporation that runs its main website on a dated version of microsoft IIS 6.0 with ASP. this company worked hard to ensure its pretty pictures had maximum market placement, and slashdot is no exception.
