Spam and phishing mail

Who’s №1?

If you’re looking for Internet security software online, you’ll see we’re right up there in the ratings. And it seems that we’re №1 with spammers too.

You might think we’d be happy to have our name all over this spam – pretty good advertising. But because we’re in the security business, we take a dim view of this type of thing: spam is criminal, spreads malware and hogs bandwidth. The link leads to a site selling all sorts of cheap (i.e. pirate) software:

This is advertising we don’t need. Sure, we want people to buy our product, because we know it’s good. And on a more banal note, yes, our product is our bread and butter.

You might save money buying a pirate version, but think of the consequences. You get a product which won’t work properly (leaving your computer at risk) and you’ll be egging the cybercriminals, malware writers and spammers on to new heights.

We matched private and public DNS data for the SUNBURST-malware root C2 domain with the CNAME records, to identify who was targeted for further exploitation. In total, we analyzed 1722 DNS records, leading to 1026 unique target name parts and 964 unique UIDs.
