New Rowhammer Exploit Enables Hackers to Bypass Mitigations

The Rowhammer exploit was first discovered in 2014 and was shown to allow attackers to take control of devices by targeting DRAM memory cells. Rowhammer attacks take advantage of the close proximity of memory cells, causing them to leak their charge and alter the content of neighboring memory cells. The attack involves delivering constant read-write operations using carefully crafted memory access patterns to continuously activate the...

NIST Revises Guidance on Passwords

The National Institute of Standards and Technology (NIST) has issued new guidance on passwords. It is standard practice to make passwords stronger by using a combination of capital letters, lower case letters, numbers and special characters. While that certainly makes it harder for cybercriminals to crack passwords using brute force methods, it also makes passwords particularly difficult to remember. In practice, forcing users to add...
