Looks like it's from Alibaba cloud

Another sample, UC browser: https://apkcombo.com/uc-browser/com.UCMobile.intl/

Smali file `smali\com\alibaba\wireless\security\framework\d.smali` contains following strings

libsgmain
libsgsecuritybody
libsgmiddletier

Since libsmain.so is an APK file, you can decompile it or load in jadx

com.globe.gcash.android and id.dana

lib/xxx/libsgmain.so!lib/xxx/libsgmainso-XXXX.so (as mentioned above)

com/alibaba/wireless/security/open/SecException
alibaba/wireless/security/framework/SGPluginExtras
us-ummt.alibaba.com
com/alibaba/wireless/security/open/litevm/LiteVMParameterWrapper

LibChecker has a rule for it. "阿里聚安全" translates to "Alibaba Security": https://github.com/LibChecker/LibChecker-Rules/blob/master/native-libs/libsgmain.so.json

Okay, thanks for the info! I will try to find time to create a rule for it.
