Urgent Privacy Issue?

[Yuno Grinberryall]

Hindi ko alam kung paano or security or privacy issue ba ito, iyong LTC at BCH ko sa coinbase nagkaroon ng bagong address pero di naman ako nag create noon? At hindi na nadedelete ang newly created addresses.
Anyone guys pa help? Should I worry or not? Kasi may kaunting naipon na ako doon and nadadagdagan pa.
