Europe's Supermarket Freezers Hit by Remote Temperature Tampering, Cause Unconfirmed

·9 views

Staff at an ICA Kvantum store in Sjöbo, Sweden, found refrigeration units remotely set to around 50°C overnight on 2 November, forcing them to discard spoiled stock. Coop, Ahold Delhaize, Colruyt and Carrefour Belgium also reported similar unauthorized temperature changes across multiple stores. The incidents follow a reported earlier wave in France three weeks prior, which affected hundreds of supermarkets with substantial food losses. Companies describe the events variously as tampering or an IT incident, and no group has claimed responsibility or been publicly identified. Investigators have not yet confirmed whether the incidents are linked or how attackers gained access to the systems.

Why Per-Attempt Timeouts Break Retry Loops and How to Fix Them

A retry loop with a 10-second timeout and three retries can run far longer than a caller expects, because per-attempt timeouts do not limit the total operation time. Backoff delays and pre-request work such as DNS lookups or token refreshes add further latency on top of the attempts themselves. The article recommends starting from an overall time budget and dividing it across attempts, using a monotonic clock to track remaining time. It also suggests propagating a shared deadline through the call stack, as gRPC does, so downstream calls draw from one budget. Tradeoffs to weigh include starved final calls, budget sharing in parallel requests, and server-side work that continues after a client-side timeout, which makes idempotent retried writes important.

Researcher finds AI-agent guardrail flaw that let unapproved actions run, prompting fix

A security researcher found that airlock, a prompt-injection guardrail in the Hermes plugin catalog, could be bypassed during unattended hermes -z turns. The guardrail checked a flag that did not reflect that the session was unattended, so actions requiring approval ran without any. The maintainer fixed the issue in airlock 0.2.3, which now queries the approval layer and covers CLI subagents, and the fix was merged via PR #144871. The flaw was disclosed through coordinated disclosure and published as advisory GHSA-mgf8-gh7g-q4rg. The researcher argues that this kind of flaw reflects a broader design weakness in guardrails that decide at the door based on proxy signals.
