Stealing WordPress credentials

Yesterday WordFence published a scary article titled "Large Scale Attack Campaign Targets Database Credentials". Article describes a recent mass-scanning attack of WordPress sites. The purpose of the attack was stealing WordPress configuration files - and therefore usernames/passwords of WordPress admins.

As with the XSS campaigns, almost all of the attacks are targeted at older vulnerabilities in outdated plugins or themes that allow files to be downloaded or exported. In this case the attackers are attempting to download wp-config.php, a file critical to all WordPress installations which contains database credentials and connection information, in addition to authentication unique keys and salts.

Since WordFence is in the business of selling "the best WordPress security", they have little intention to explain how these attacks really work.

Instead, they blatantly advertise their product as a remedy for everything:

All Wordfence users, including sites running the free version of Wordfence, and Wordfence Premium, are protected against these attacks.

That's really not helpful, so let me fix that. smile

Update of unpackers

I'm trying to get back into reversing. Slowly.

So, here's a long-promised update to Molebox unpacker. It fixes unpacking of very, VERY, VERY old Molebox versions. The only file I have ever seen packed with it, is SCWU role playing game.

Enigma Virtual Box unpacker

This was done long time ago but I never posted it publicly. Support for Enigma Virtual Box 9.30/9.40. Should support 9.50 but it's not tested.

About the long silence

Hello all!

It's been almost a year since my last post. I guess some explanation is in order. And it's actually very simple.

I got burned out.

I took on too much at once. My daily job. Personal life. This blog. Paid side projects. It was all fun until it wasn't. One night I finished my side project at 3AM, sent the finished code to the guy and went to sleep. Next day I just couldn't wake up and get to work. So, I said to myself, "It's alright, weekend is coming, I'll get some more sleep and everything will be fine again!"

It wasn't.

My brain still refused to work and I could barely function. I stopped answering my emails. Stopped managing the blog. Stopped pretty much everything. Whatever I did, it wasn't fun. And that's how I spent last year or so.

It's slowly getting better. Reversing stuff feels fun again. I might even write a proper blogpost or two in the near future. Who knows..

Now you know it. Take care and try not to end up like me!

Unity3D protection in “AU2” dance games, part 2

Last December I wrote a blog post explaining how some of the AU2 dance games were protected. Apparently, the protection author read the blog post and updated his protection. smile This blog post will explain how the protection was changed and suggest several ways of dealing with the new features.

This analysis covers:

April update of unpackers

Molebox VS unpacker

This is a quite big update for Molebox VS unpacker. It fixes most of the bugs I'm aware of:

  • Supports Molebox GPL version
  • Removes "anti-hacking" protection
  • Supports BOX files in sub-directories
  • Shows embedded command-line
  • Main executable will be named {yourfile}_unpacked.exe
  • Fix calculation of SizeOfImage in edge cases
  • Fix decryption in edge cases

It's still not perfect and will fail in some situations - but I didn't want to postpone the release any longer. Please let me know if it crashes for you and I'll try to fix the problem. smile

March update of unpackers

Enigma VirtualBox unpacker

  • Unpacker will refuse to run if there is not enough space in TMP folder and/or in working directory
  • PE header size was calculated incorrectly in some cases
  • TLS directory was not detected correctly for some files

Setting TMP folder to a RAM drive was a good idea in 1990s. Now it's year 2019 and you can't manage virtual memory better than Windows already do. But some people apparently still try, so I added checks to stop them from shooting themselves in the foot.

Molebox VS unpacker

  • Added support for a very old version on Molebox VS, as reported by death

The fix was actually implemented a long time ago, I just didn't make the announcement.
