Researchers discover major roadblock in alleviating network congestion

When users want to send data over the internet faster than the network can handle, congestion can occur — the same way traffic congestion snarls the morning commute into a big city. Computers and devices that transmit data over the internet break the data down into smaller packets and use a special algorithm to decide …

MIT Researchers Discover New Flaw in Apple M1 CPUs That Can’t Be Patched

A novel hardware attack dubbed PACMAN has been demonstrated against Apple’s M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages “speculative execution attacks to bypass an important memory protection mechanism, ARM Pointer Authentication, a security feature that is used to enforce pointer integrity,” …
