GitHub Copilot moved into Slack and Microsoft Teams on the same day

Both shipped on August 21 in public preview. Mention @GitHub in a channel and the agent triages issues, investigates failures, writes changes in a cloud sandbox and opens a pull request, with the conversation attached. The interesting part is not the capability list, which is familiar, but the room it moved into: the place where work gets discussed rather than written.

Encrypting the instruction walks it straight past the guardrail

Researchers at Adversa hid a prompt injection as ciphertext with the key next to it. Grok decrypted it in its own sandbox and sent the user's name, location, and chat history to an attacker's server, without a warning and without asking.
