Malware spam: "Berendsen UK Ltd Invoice 60020918 117" / "donotreply@berendsen.co.uk"

UPDATE: a new spam run using this firm's name is active as of 24th February. For more information click here.

Berendsen is a wholly legitimate firm in the textiles and laundry business. They are not sending out this spam, nor have their systems been compromised in any way. Instead, this email is a forgery with a malicious Word document attached.

Attached is a malicious Word document with a zero detection rate which contains a malicious macro [pastebin], and this in turn downloads a binary from:


This executable is saved as %TEMP%\LAVUBDAJLCD.exe and has a VirusTotal detection rate of 2/57 (Norman AV identified it as Dridex).

Automated analysis [1] [2] [3] [4] is proving difficult, a contact suggests that Botnet 125 (which is behind this spam run) is having stability problems. Shame.
