New 'RAMBleed' Rowhammer attack can now steal data, not just alter it

zdnet.com/article/ramble…
RAMBleed uses Rowhammer attacks in a clever way that can allow attackers to infer data stored inside a RAM card, not just alter it for LPE attacks, as it was possible until now
The RAMBleed attack required researchers to come up with new techniques for manipulating RAM and memory allocations, in order for the attacker to control how data was mapped inside a physical RAM card
In practice, this allowed researchers to steal an RSA private key from a SSH service on a Linux server
More info on the RAMBleed website: rambleed.com

And research paper: rambleed.com/docs/20190603-…
Also, a quick overview of all the previous Rowhammer attack techniques. Boy, there sure is a lot of them.
Also, something of note. ECC-protected RAM isn't safe. It actually helps attackers.

Go figure.
