A cyber attack on French supermarket freezers and a halted US probe into suspicious oil bets point to weak guardrails on both food supply and markets.

• Hackers raised the temperature in internet-connected fridges and freezers at 300 French supermarkets, ruining food and starting fires.
• France called it a cyber attack on the food supply, a warning that connected appliances anywhere are now a target.
• At the CFTC, staff were told to drop their analysis of suspicious oil trades placed around Trump's reversal on striking Iran's power plants.
• Those staff are reportedly no longer at the agency, which critics call a direct move to shut down the market cops.
• Ukrainian drone strikes on Russian data centers run by Yandex appear to have knocked out a large share of Russian bot traffic overnight.

Outlook: Expect more pressure on US market regulators and growing scrutiny of corruption cases close to Trump as the midterms approach, while connected-device attacks look likely to spread.
