For a change this is about an exploit, rather than a malspam email.
I was reading posts on a well known tech forum, when I got a sudden divert and a .hta file attempted to download. Of course I immediately saved the file, rather than letting it run. I won’t name the tech forum at this stage, to allow the admin time to investigate and check what advert I think caused it. It was an advert for HP laserjet printers that was not using flash but did have moving images. I think the divert happened when I moused over the advert whilst scrolling down the page.
Anyway the divert was to https://eiyahpornhub.org/5101454380687/6481137a7f7240574c225b198be9c16d/34cacd8a11e39b3bbc01955b9b1eac15.html ( note the “safe Secure ” https: link) HTTPS does not mean safe. It means secure from interception in normal circumstances.
Update: it looks like the link is dynamically created and changes on each visit from the referrer ( the dodgy advert) . I haven’t been able to get back to the site and get a 404 every time. I can get the .jse file and multiple visits to that is allowed. Lots of exploits refuse to let the same IP & referral id more than 1 attempt to visits to stop antivirus companies and researchers investigating them easily.
This downloaded FlashPlayer.hta ( VirusTotal ) ( Payload Security) which is just an instruction to the computer to use PowerShell to download silently in the background https://eiyahpornhub.org/5101454380687/1491733844471718/FlashPlayer.jse ( VirusTotal ) ( Payload Security) which isn’t showing any further downloads, so I have no idea at this stage what the end malware is intended to be.
This seems very similar to the campaign posted on https://www.bleepingcomputer.com/news/security/skype-malvertising-campaign-pushes-fake-flash-player/
In both cases nobody has actually got the final payload. All I managed to get was https://eiyahpornhub.org/67d05900efa21668e417c34f5adb32e1.mp4 ( now down) VirusTotal | MALWR which is just plain txt ( possibly encrypted) that would need the original jse file to decrypt it to something useful. (If it is encrypted txt and not just some sort of identity string )
Whole package as a P/W zip file “infected” 9 april_ fake_flash_player_malvertising just in case some other researcher can make use of it
eiyahpornhub.org was registered yesterday 8 April 2021 https://whois.icann.org/en/lookup?name=eiyahpornhub.org I very much doubt that the listed registrants details are correct. They are probably stolen details and credit card used to register this domain
