On Thursday the US government effectively banned Kaspersky security software on US servers on national security grounds, or at least made it useless given the lack of updates come September. Then, as we were filming this week's Kettle, 12 members of Kaspersky's C-suite were sanctioned as well - although not the Russian business' eponymous CEO Eugene. So what on earth is going on? Is this overreach by the US government or is there something more sinister going on? Joining us on this week's Kettle is our security editor Jessica Lyons to give us the full story, along with Tom Claburn to add in wisdom on the software side. As ever The Register's editor Chris Williams has pithy comment and your host is Iain Thomson, with producer Nicole Hemsoth Prickett turning chat into gold.
