Last week I was browsing Twitter when I found a tweet from Jaromir Horejsi about a spam mail with a Locky downloader that was personalized with his surname. It was the same day that I received a spam too, also with my surname in it. I’m always happy when this happens as it gives me an opportunity to go down the rabbit hole and check what’s hidden in there.
Inside Locky’s downloader
Locky is back
I received a nice spam mail today. Normally the anti-spam plugin on the mail server does a really nice job to filter these out but this one got through. As I had some spare time, I decided to check what’s going on. First look at the mail revealed that it is a malicious downloader. Naturally, I was curious about the payload, so I decided to investigate further.
