The Solar System is now flooded with ganker and griefer. If you would like to defend it from the current thargoid attack, use private group mode(such as Anti-Xeno-Initiative) or solo mode. If you'd like to play in open mode, here's the tip for escape when interdicted by those gankers:

De-throttle to 0, submit to interdiction, when you get back to normal space, boost and immidiately select a near system on the left panal and engage hyper drive(since high wake charge won't be affected by mass-lock factor), meanwhile divert your power to system and engine to survive the attack.

This is a tip for the beginner, it should give you relatively larger chance to survive the attack.
