Pump-and-dump scamster pleads guilty

Thursday, October 21st, 2010

An Arizona man, James Bragg, recently pleaded guilty of conspriacy to commit securities fraud, and now faces a large fine and possible prison term for the pump-and-dump scams he perpetrated using botnets and spam.

Pump-and-dump scams involve hyping the value of a cheap/worthless stock by advertising it heavily over the internet using spam. Typically, the stock is bought by the attacker who then sends out the mails to hype the stock, which creates buying interest, and then the attacker sells all their stock, cashing in on the falsely inflated value.

In this case, the defendant had allegedly hired people to use botnets to distribute his messages. The botnets were also used to compromise private accounts so that these could be used to buy up large amounts of the stocks in question. He also faces charges from sending spam.

Old style Email Worm spreading rapidly

Saturday, September 11th, 2010

In something of a blast from the past, an email borne worm has been sighted spreading around the internet.

Although we’ve not seen too many actual attacks from this, it’s been widely reported in the media, perhaps as it’s quite a novelty these days to see a worm spreading in this way.

It spreads itself as an executable in email, but disguises itself as a PDF file, when executed it attempts to download some other malicious files on the victim machine, and drops some files in an attempt to let the worm spread via autorun.

K7 Total Security detects this worm as  ”Emailworm (0019e4ae1)” (yeah, it’s that uninteresting!)

If you’re interested in more, Dan Goodin has written a short piece about the worm on The Register http://www.theregister.co.uk/2010/09/10/email_worm_spreading/
