Lancashire Constabulary monitors its emails, and you are advised that any e-mail you send may be subject to monitoring.

This e-mail has been scanned for the presence of computer viruses.

The attachment appears contain some sort of malicious OLE object rather than a macro, but so far I have not been able to analyse it. Furthermore, this document does not seem to open properly in other applications, so I suspect that it contains an unknown exploit. Analysis is still pending.

The VirusTotal report shows a detection rate of zero. The Malwr report is inconclusive.

Other analysis is pending please check back.

Another version of this is in circulation, also with zero detections at VirusTotal.  The Hybrid Analysis for both samples in inconclusive [1] [2].

An analysis of the documents shows an HTTP request to:


All this returns is the IP address of the computer opening the document. Although not malicious in itself, you might want to look out for it as an indicator of compromise.

All the attachments I have seen so far are corrupt, with an extra byte at the beginning (thanks). If you opened it and got a screen like this:

Source: Malwr.com
..then you are not infected. Incidentally, this only infects Windows PCs anyway.

The "fixed" malicious documents have a detection rate of about 6/56 [1] [2] [3] - analysis of these documents is pending, although I can tell you that they create a malicious file in %TEMP%\HichAz2.exe.

The Hybrid Analysis reports for the documents can be found here [1] [2] [3] show that the macros [example] in the document download a binary from the following locations:


At present this has a zero detection rate at VirusTotal (MD5 7f0076993f2d8a4629ea7b0df5b9bddd). Those reports in addition to this Malwr report indicate malicious traffic to the following IPs: (Elvsoft SRL, Romania / Coreix Ltd, UK) (Web Drive Ltd, New Zealand) (Online SAS / Iliad Entreprises / Poney Telecom, France) (Trinity College Hartford, US)

The payload is probably the Shifu banking trojan.

My sister received this and opened it and then because she was worried, forwarded it to me and I then opened it. We had no idea it was fake, what should we do? Is it likely to cause any damage? Thank you.

i had a look at the sample and the header does seem off a bit from a normal Doc. I used forensic tools to carved the file and was able to recover some of the Doc including the macros which I dumped to text files.

seems to be Dridex but it appears there is something not quite right about the doc file this could be accidental or something new. Maybe this will help in your analysis.

@Adam, there's an extra byte right at the beginning of the documents which is screwing it up. If you remove it, then the malware works normally (h/t @hahn_katja.

Adam Hughes said...

looks like it creates an exe in temp called HichAz2.exe

Adam Hughes said...


So it does, that will teach me to rely on 'File' command without manually checking :)

Thanks for the heads up

If you want to get rid of it, try the different scanners from different vendors. Like if you use Norton, try the Sophos scanner: https://www.sophos.com/en-us/products/free-tools/virus-removal-tool.aspx

Thanks Kristian, i'll run this now. :)

Thanks to Kristian Samstad for the SOPHOS link. Shopos found the trojan on the desktop, for some reason... and removed it.
