Using SD Maid, I was looking around with file explorer and came across this directory in the efs folder, and I have no clue what it is, if its malicious or not. Its the only directory in the efs folder with a name that isnt clearly defined. (like modem, data etc) I tried Googling the directory and file names but got nothing.
Device info: USC Samsung Galaxy S5 (SM-G900R4, Qualcomm, codename klte); rooted and slightly customized using hidden menu settings; software up to date.
This is how it appears in SD Maid:
/efs/U0BwJ04kmkmm-Bg7zUZgoEY7pn8_/zm0WY41Y7rpx3kcVTTDWeh8VFRU_ (size: 1.05kb, date 1/1/14)
/efs/U0BwJ04kmkmm-Bg7zUZgoEY7pn8_/qen2gEqW2A+OTD0KpoESJiYnrk_ (size:1.05kb, date 1/1/14)
I don't know, if anyone that has seen it before.
