"Did you know that Bank Safety Deposit Boxes arent XXX% safe There are hundreds of cases a year where valuables go missing. And unlike cash deposits safety deposit boxes arent insured. You need a digital safety deposit box. Use Keypo"

"@litcapital Yeah but XX% of fund manager didn't beat the S&P XXX so he's technically a tier X fund manager now"

"9/ When Ledger shared their findings with Mediatek they commented that EMFI attacks areout of scopefor (our chipsets). Like many standard microcontroller circuits (our chipsets are) designed for use in consumer productsnotfor applications such as finance"

"2/ Ledger's security team demonstrated it can gain control of the Mediatek Dimensity 7300 processor which is used in many android phones using a technique called Electro-Magnetic Fault Injection (EMFI)"

"8/ So this is the attack: X. Modify the phones circuit board to put the processor into debugging mode. X. Use EMFI to disrupt the security checks and restrictions. Once those checks are disrupted they could execute arbitrary code aka they have control of the device"

"10/ This vulnerability isnt unique to Mediatek. Most consumer chips arent hardened against physical attacks. Notably Ledgers secure element and the chips in your credit cards were designed to make these types of attacks significantly harder"
