At first, the potential victim receives a spam email telling him/her about the successful purchase of tickets from Delta Air Lines. The email goes on and informs the recipient that an additional document (the so called “passenger itinerary receipt”) has been attached to confirm the purchase.
In an usual scenario, the unsuspecting user would hurry up to open the attachment and see for himself..how easy is to get infected with malware.
The file attached to the emasil, dubbed delta_8612Z.zip, carries in fact the Troj/Inject-EW Trojan horse, a piece of malicious software ready to silently install itself onto the computer when the user accesses the file.
Needless to say, one advice beats all: take your time and think it over instead of rushing to open shady files sent by shady expeditors.
