A supply chain attack compromised an Anthropic Claude extension distributed through Cursor, affecting approximately 5,000 developer machines. Wired reported that flawed code in the tainted extension prevented the attacker from fully compromising some systems. Ars Technica noted the extension remained backdoored for nearly 12 hours, though the method by which attackers gained access to Anthropic's verified Cursor account remains unclear.

Where they diverge

Both outlets cover the same incident but emphasize different aspects. Wired highlights the fortunate technical flaw that limited damage; Ars Technica focuses on the duration of the compromise and the unresolved question of how the attacker obtained account access.
