AIR-FI attack turns RAM into a makeshift Wi-Fi signal source

Experts from Israel’s Ben-Gurion University have demonstrated the AIR-FI attack, which turns RAM into Wi-Fi. In fact, this is a new method of extracting data from machines that are physically isolated from any networks and potentially dangerous peripherals. Such computers are often found in government systems and corporate networks, they store secret documents, as well as classified and confidential information. This time, the researchers proposed turning the RAM into an impromptu wireless emitter for transmitting data “over the air.” Since Wi-Fi is radio waves, which is very close to electromagnetic waves, the researchers write that, in theory, a hacker can manipulate the RAM power to generate electromagnetic waves with a frequency corresponding to the frequency of the Wi-Fi signal (2.4 …

Modern RAM is still vulnerable to Rowhammer attacks

Recently, I wrote all about the vulnerabilities of Intel and AMD processors, and in the meantime, a group of researchers from universities in the Netherlands and Switzerland published a report according to which modern RAM memory is vulnerable to Rowhammer attacks, despite all the protective measures taken by manufacturers over the past six years. new Rowhammer variation with TRR bypass is currently tracked under CVE-2020-10255. Let me remind you that researchers from Carnegie Mellon University invented the original Rowhammer attack back in 2014. Its essence was that a certain effect on the memory cells can lead to the fact that electromagnetic radiation will affect neighboring cells, and the values of the bits in them will change. “Over the years since …
