I'm seeing much more spam with zip attachments. The messages are carefully crafted to induce any busy office worker to click on them without thinking, and often seem to be targeted at individuals within the company. I'm not about to click on one of these, but if I did, what would happen? Roger Wilson
This is a common way of distributing botnet-controlled Trojan files, such as the ZBot banking Trojan, ideally a variant known as Prg. The basic idea is to capture and simulate all the keystrokes used to access your (preferably commercial) bank account to perform a fraudulent money transfer that is almost indistinguishable from the real thing. ZBot can also attempt to disable your firewall, steal credit card numbers, take snapshots of your screen and download extra components as required. Anti-virus software should block it, including online scanners such as Kaspersky. However, anyone who finds it would also need to change their banking and other passwords.
