'Cyber-attack' hits Mastercard site
“Credit card company Mastercard’s website is currently unavailable due to an apparent hacking campaign organised in response to the company’s refusal to handle donations to the WikiLeaks website.
The attack, called ‘operation: payback’ has apparently been organised by internet freedom of speech activists, calling themselves ‘Anonymous’.
Mastercard announced on Monday it would no longer handle donations to WikiLeaks as the website was engaged in ‘illegal activity’.”
