Copyright phishing email targeting academics

It has been reported that the academic staff received emails claiming ‘alleged copyright violations in classroom’ from what appears to be (but is not) a US law firm. The email comes with an attachment 'details.zip' which contains a pdf file named 'Details.pdf. This pdf contains a script which displays a popup saying the user needs to get and additional font in the ‘Legal MT Font Family’.  If a user google the “Legal MT” font, it takes him to a malicious website contains malware download. The advantage here is that the spammer doesn’t have to send malicious file which would then be highly likely to be blocked by the Google spam services.

The email text contains some kind of law suit warning and the sender domain is traverse-legal.com which is a close match to the legitimate law firm www.traverselegal.com.

Staff are reminded to be vigilant about opening suspicious or unexpected emails containing links or attachments.

An example of the current campaign received by academics is as shown:

CryptoWall Ransomware Campaign Impacting New Zealand organisations - 19 March 2015

In recent months, it has been observed that the CryptoWall ransomware campaign through email is on rise. The CryptoWall ransomware is a Trojan horse that encrypts files on the compromised computer and then prompts the user to purchase a key in order to decrypt them.  The CryptoWall ransomware infects the Windows based Operating Systems only. The authors of these malicious threats have a very strong financial motive for infecting as many computers as possible, and have put substantial resources into making these threats prevalent.  New variants are seen all the time and these threat are impacting New Zealand organizations.

These CryptoWall Ransomware Campaign emails would contain an attachment that, when opened, infects the computer. These .zip attachments contain executables that are disguised as PDF files: they have a PDF icon and are typically named something like FORM_101513.pdf.exe. Since Microsoft does not show extensions by default, they look like normal PDF files and trick victims into opening them.

The current campaign is using a "Resume" theme with a zip file attachment containing a malicious JavaScript file.

An example of the current campaign received by University staff is as shown:
