Ledger security team discloses hardware vulnerability in the chip used by Trezor Safe 7, Trezor claims user funds are safe
According to ChainCatcher, as reported by The Block, the Donjon security team under Ledger successfully bypassed the firmware verification mechanism of the TROPIC01 chip used in the Trezor Safe 7 through a precise laser attack conducted in a laboratory environment. This allowed attackers holding the physical device to load unauthorized firmware. Chip manufacturer Tropic Square further discovered an additional attack path in the chip’s MAC-and-Destroy security mechanism for PIN verification, but details will not be disclosed until an enhanced version of the chip is released at the end of 2026.
Trezor stated that PINs, mnemonic backups, and private keys have never been stored on a single chip. Partners have been notified, and regular users do not need to take action. Currently, the feasibility of attacks can be reduced by disabling the chip’s MAINTENANCE mode.

BUZZ-Revolution Medicines stock drops due to concerns over pancreatic cancer drug data
On October 8, Revolution Medicines (RVMD.O) shares fell 8.1% in afternoon trading to $185.91. RBC Capital Markets stated that the share price decline appeared to be driven by the latest U.S. Food and Drug Administration (FDA) review documents regarding the company's pancreatic cancer drug Rasonque, particularly the disclosure of objective response rate data for specific RAS mutation subgroups. RBC pointed out that overall survival, rather than objective response rate, is a more meaningful indicator of efficacy, and that the sell-off overlooked Rasonque's broad activity across a variety of RAS mutation subgroups. RBC stated: "While we acknowledge that today's share price decline takes place against the backdrop of overall weakness in the biotech sector, we still believe that the market's reaction to the FDA review documents is an overreaction, given that the drug was approved on the basis of highly clinically meaningful efficacy and has received positive feedback from physicians." Including intraday fluctuations, the stock has more than doubled year-to-date.
