Will BragJack-style AI browser agent hijacking attacks lead to 20+ documented account compromises by end of 2026?

BragJack, a proof-of-concept attack by security researcher Gal Weizman (Forever Security), demonstrates how malicious browser extensions can hijack AI assistants in Chrome, Edge, Opera, and Perplexity Comet via prompt-forcing techniques. The attack earned $20k+ in bounties and two CVEs. This market assesses whether similar extension-based hijacking will result in real-world account compromises.

Resolution Criteria

YES if reputable security vendors, CISA, or major press outlets document 20+ confirmed cases of user accounts compromised via BragJack-style extension hijacking of AI assistants by Dec 31, 2026. Sources must cite browser extension-based prompt forcing as the attack mechanism.
