back to article Botnet pierces Microsoft Live through audio captchas

The prolific Pushdo spam botnet has found a new way to penetrate Microsoft's by exploiting weaknesses in the audio captchas designed to prevent automated scripts from accessing the popular email service. A new version of the bot causes infected PCs to pull down audio captchas and return the correct response …

    Well, some people gave their system password for chocolate not long ago, so why not some other stupid losers give their financial information for porn ?

    It angle : Was there any chocolate bar fetishes in the proposed porn ? 8p

      People gave something they claimed to be their password, in exchange for real chocolate.

    If They Can Decode...

    ...static masked voice, they could have made more money selling the technology to DARPA.

    I'll have another 211 while we ponder that.

    " send email through accounts with a address, which are whitelisted by many spam filters."

    Not mine. Not as long as Microsoft has no working abuse contacts.

    Mamma mia!

    "Mamma mia! your grandmother is doing so strange things here! Look at these delineations!"

    That is hilarious! Especially if you sing it using the tune from the ABBA song Mamma Mia - just add the lyric "my my" between "here" and "look" as in the original song and it almost fits the tune perfectly!

    I knew these spammers were really into 70's pop and disco music! It all adds up now!

    More likely, the audio captcha is sent to active participants in 3rd-world countries who are paid a couple of cents for each Captcha they decypher correctly. Worked for the visual ones, so why not for this one.

    Clever.. or not..

    All that technology.. and then "Mamma mia! your grandmother is doing so strange things here! Look at these delineations!"

    It's like a clever kid allowed his stupid cousin, who may also be his sister, help with the coding.

      I'd say

      It looks like Chinese pushed through the translation mangle at bablefish.

        Thumb Up

        Chinese whispers

        I put "look at these delineations" into Google translate, taking it to and from Chinese and it came back as "take a look at these paintings France"

    The websites are going to need to rethink this whole captchas mess

    I think computers would have an easier time than I do of decoding some of the ones I've seen recently.

    Ironic: Like a virus scanner

    Just like a virus scanner, scans for signatures that indicate there may be a virus, this could scan for the signature of the captcha data, if it is a new captcha send it off for decoding and a new signature added to the captchas database.

    This would explain!

    So this is why I've been receiving a lot of add requests from or such asking me to see her nekkid cam... really, these bot accounts have been around for the past 6 months, maybe more.

    Looks like MSFT needs to add some complexity to the audio files. Some random background noise, coupled with some salting to botch MD5/SHA1 hash checks should do the trick.
