Zipping Images and Documents – Did That Really Help?

Published: April 14, 2010 Reading time: 2 min

Does anyone really care about opening a zip file to examine an RTF or JPEG file? This task—combined with a dull, unexciting, unstimulating subject line—competes with the content of the email to win a race of worthlessness. Spammers have traditionally used zip files to carry executables, but in most cases the subject line or the content of the message made an effort to encourage users to open the attachment. There are cases of spamming attacks in which HTML attachments opened up a fully functional Web page, capable of carrying sensitive user information back to the fraudsters. However, with this latest spam attack using zipped files, not only have the spammers made an attempt to escape anti-spam filters, they’re missing out on reaching any users as well. The scope of returns for these messages looks to be much less rewarding than other comparable attacks. ...

Of course I’m talking about football. When I say football I mean the game that is played with one ball thas is kicked with the foot, not the other game that is known as football in the US even though it’s played using the hands. Anyway I don’t like football at all, it’s too boring fo me. But, at least in Europe, everyone loves football. And one of the best national championships is the Spanish one, with the 2 biggest teams being Real Madrid and F.C. Barcelona. Every time they play against each other, millions of people watch that game, and news about it are going around all the time. Last Saturday they played in Madrid, and being this such a popular match, cybercriminals couldn’t miss this opportunity. ...

WordPress blog pages redirected to rogue site

Published: April 12, 2010 Reading time: 1 min

Brian Krebs, in his “Krebs on Security” blog is reporting that a large number of WordPress blog pages have been hacked to redirected visitors to networkads.net that downloads rogue security applications onto their machines. Also, the owners of the blogs are locked out of access. “It’s not clear yet whether the point of compromise is a WordPress vulnerability (users of the latest, patched version appear to be most affected), a malicious WordPress plugin, or if a common service provider may be the culprit. However, nearly every site owner affected so far reports that Network Solutions is their current Web hosting provider,” Krebs wrote. ...

There is a Lot of Spam Out There…

Published: April 10, 2010 Reading time: 3 min

…and some of it masquerades as “marketing” and “newsletter” emails. In March 2010, spam continued to account for a high percentage of all email traffic, peaking at 93.6% of all messages. The majority of this spam email was sent using certain tactics that were deployed to hijack unsecured computers and hide the senders’ identity. Recently, however, there has been an uptick in spam “marketing” and “newsletter” emails. These spam marketing and newsletter emails share one significant commonality with “regular” spam emails, which is that they are unwanted email messages sent to individuals who have no formal relationship with the message sender. ...

Don't tell spammers that you're on vacation

Published: April 9, 2010 Reading time: 3 min

Microsoft has made the right decision to temporarily turn off Hotmail’s vacation (e.g., out-of-office) reply feature. Flip the switch off permanently, I say. “In our fight against spam, we sometimes have to make hard choices, and we had to make one this week. We discovered that spammers were using Hotmail’s automatic vacation reply feature to send spam from their Hotmail accounts,” Krish Vitaldevara, Windows Live Hotmail lead program manager, blogged late yesterday. I missed the post because of Apple’s iPhone OS 4 launch. I spotted the announcement first at LiveSide about an hour ago. ...
