The VBS scriptlet ensures persistence on the compromised machine by creating a registry entry HKCU\Software\Microsoft\Command Processor\AutoRun that, upon execution, again takes advantage of #Squiblydoo technique to download & execute another XML file with a VBS scriptlet. 4/6
We attribute this campaign to the ๐ฐ๐ตNorth Korea-linked APT group #Kimsuky. The Excel document contains a malicious Excel V4.0 macro that uses the #Squiblydoo technique to download and execute an XML file with a VBS scriptlet. 3/6

@TrustedSec @JamesHovious @Oddvarmoe Nice @Oddvarmoe! You might also enjoy this thread and specifically the presentation by @matthewdunwoody & @danielhbohannon including some ๐ฅ #squiblydoo evasion: https://t.co/t7TtoGDp4F
Also I have some public gists to make a crazy evasive #DailyScriptlet for the SCT itself.
Detection time!
Before continuing, please watch @matthewdunwoody & @danielhbohannon's recent talk on resilient detections:

I'll wait.
Ok, now - if you have access to it, use PE metadata. Moving a file retains its InternalName/OriginalFilename/ProductName.
CB #ThreatSight recently detected an alert for #Squiblydoo that was related to the #Smominru #botnet campaign. The attack utilizes #EternalBlue for lateral movement & #mimikatz to dump credentials. @rayrayssi @TheAdan_ https://t.co/saH6DBoenU
I don't always tweet, but when I do...it's because the amazing @bbaskin and I authored this in-depth writeup on a rampant attack! If you would like to follow me down the rabbit hole, click on the link ;) #tor #squiblydoo #ThreatHunting #ThreatIntelligence #security

We gave a large focus on *HOW* to hunt for these attacks, not just explaining what they are #DFIR

@KorbenD_Intel @James_inthe_box @securitydoggo @malwrhunterteam @Ledtech3 @pmelson @cyb3rops This generated by a builder? Looks a bit like something @buffaloverflow would punish us with.
FYI: WSF files are crazy common, unlike COM Scriptlet (SCT) that can be loaded with #squiblydoo - definitely a lot of badness here. Here's the difference: https://t.co/C0GUzAYggL
Specific bypasses require specific XML syntax.
Scriptlets (.sct) and Windows Script Components (.wsc) can be used interchangeably:
1โฃ <scriptlet><script>
2โฃ <component><script>
@subTee's regsvr32/scrobj needs "<registration" tag
@enigma0x3's pubprn.vbs cmd injection does not
We often see creative #footholds, but this isn't one of them. Pretty sure Microsoft doesn't perform #Squiblydoo attacks every hour, but we could be wrong ;) #DFIR analysts, be on the look out.
@TheColonial @singe @QW5kcmV3 @munrobotic @malcomvetter @nmonkee @hackerfantastic @domchell @daveaitel @mattifestation *Smart* bad guys are smart enough to tweak. Don't underestimate the population of dumb ones.
Example: @subTee's FEEDACDC guid in his #squiblydoo POC ๐
And if defenders rely on toolmarks to detect tools/techniques, it's just as dumb as attackers who don't change it. It works out
#DailyScriptlet update: @subTee your #squiblydoo branding dreams have come true. AV-only vendors now have explicit, long-form AV detection names:
๐ก๏ธ BitDefender: "Exploit.LNK-Squiblydoo.Gen" (most licensed AV engine)
๐ก๏ธ ClamAV: "Xml.Malware.Squiblydoo"

Cb TAU recently detected a #Squiblydoo attack attempting to leverage regsvr32.exe & scrobj.dll to download and execute scriptlet code via an #XML file. This attack also attempts to use taskeng.exe and the schedule service as persistence mechanisms via @joshpatesec @ThreatHuntress
Interesting way to call a COM CLSID:
rundll32.exe -sta {CLSID}
rundll32.exe /sta {CLSID}
Use this with @subTee's #squiblydoo COM Hijack method for a default AppLocker Bypass
Haven't found any sec-related resources with -sta (single threaded apartment)

Anyone seen this before?
For the past year, they've used @enigma0x3 bypass and renamed cscript + pubprn.vbs as:
FBI.exe + NSA.txt
YING.exe + YANG.txt: https://t.co/F8DYdofRvs
Prior to this, they relied heavily on O.G. @subTee #squiblydoo with no file renames but slowly introduced cmd obfuscation.
