New Phoenix attack bypasses Rowhammer defenses in DDR5 memory
Academic researchers have devised a new variant of Rowhammer attacks that bypass the latest protection mechanisms on DDR5 memory chips from SK Hynix. A Rowhammer attack works by repeatedly accessing specific rows of memory cells at high-speed read/write operations to cause enough electrical interference to alter the value of the nearby bits from one to […]
What is the Difference Between RAM and ROM?
Ever asked yourself ‘what’s the difference between RAM and ROM’? If you’ve seen both acronyms in action, it’s a natural question to ask, especially if you can deduce that both of those “M”s mean “Memory”. Let’s take a moment to talk about PC memory, then break down all you need to know about the difference between […]
New RAMBO attack steals data using RAM in air-gapped computers
A novel side-channel attack dubbed “RAMBO” (Radiation of Air-gapped Memory Bus for Offense) generates electromagnetic radiation from a device’s RAM to send data from air-gapped computers. Air-gapped systems, typically used in mission-critical environments with exceptionally high-security requirements, such as governments, weapon systems, and nuclear power stations, are isolated from the public internet and other networks to […]
