There are stories that are repeated in the spread of current criminal malware. From a new complaint received we learned of this new case of (ab)use of (supposedly) reputable Internet resources. This same year we have reported several cases of abuse of DropBox to host malware and Bit.ly as a shortener and concealer of the real address of the malware: > *Trojan spreads using Windows Live/Hotmail accounts and abuses Dropbox.com* > http://blog.segu-info.com.ar/2011/05/troyano-se-propaga-usando-cuentas-de.html > *Phishing with Trojan hosted on DropBox.com* > http://blog.segu-info.com.ar/2011/03/phishing-con-troyano-alojado-en.html > *Number of malware downloads from shorteners* The malicious mail that arrives is this: ![Correos propagan malware en Dropbox con ayuda de Bit.ly](https://www.ventasdeseguridad.com/media/feedgator/images/9_20111215_malspam_comprovante_fake_mail.jpg) It can be seen that the link to the supposed attached voucher, Deposito14122011.doc, is actually a *link http://bitly.com/u\[DELETED\]E*, from the Bit.ly shortener, which leads to *http://dl.dropbox.com/u/5\[DELETED\]5/Deposito14122011.zip* which is a banking malware as we checked in VirusTotal where it is barely detected by 2 of 43 antivirus, that is, practically no antivirus. After 12 hours of the complaint made by Segu-Info, the abused resources are still active. This shows that even companies like Bit.ly and Dropbox are not living up to their responsibility. ![Correos propagan malware en Dropbox con ayuda de Bit.ly](https://www.ventasdeseguridad.com/media/feedgator/images/9_20111215_bitly_stats.jpg)On the other hand and seeing the statistics of Bit.ly on that link, in the last 24 hours there were almost 1500 clicks to that address, which indicates that we must continue to alert and educate people about these tricks used by criminals, about the prudent use of the Internet. - Publicidad - Update 16/12 10hs: the malicious file seems to have been updated and the current one is detected by 15/43 AV in VT where it is identified as a banking Trojan. Update 16/12 10:20hs: the link Bit.ly has been marked as dangerous after 24 hours after the complaint was made. The malicious file in DropBox is still online. **[See original.](http://feedproxy.google.com/~r/NoticiasSeguridadInformatica/~3/KhGuC4O-F4Y/correos-propagan-malware-en-dropbox-con.html "Correos propagan malware en Dropbox con ayuda de B")** ### No comments • If you're already registered, please log in first.
