Two Russian hacktivist groups have claimed they worked together on the waves of freezer hacks which have affected European supermarkets.
Noname057(16) and Z-Pentest Alliance posted on Telegram that they were responsible, bragging that they had "once again demonstrated a high level of skill and precision".
But their posts and channels have now been deleted and their claims are being met with some scepticism.
