Interesting discussion about possible security breach, but as a member of the public I reckon that this is something that shouldn't be covered up. The taxpayer will have to pay to fix it.
We had a B767-300 suffer similar damage at Heathrow when the handling agent's tow tug ran away and took a bite out of the forward hold's belly skin. Repair was by replacement of the damaged frames, stringers and skin. Follow-up was an 'overblow' check to seat all the parts and work harden the repaired area. Total bill came to just over US$8 million. Plus the aircraft was out of service for nearly three months.
I believe that wind damage is classed as an Act of God by the insurers. So, now you know the awful truth. God is a Mover...
