scientists are warning consumers that memory attacks and other
so-called fileless exploits have reached an all-time high. Unlike
traditional viruses and other types of malware, these attacks don’t
require a user to download and run a sketchy application.
these exploits rely on the ability to write instructions directly to
RAM. As a result, they’re capable of attacking mobile devices, PCs
and servers with equal severity. Since no actual files are involved,
traditional antivirus software isn’t capable of detecting them.
feel that they’ve found ways of reducing the amount of damage caused
by these attacks, though they initially had some difficulty pinning
down how these attacks kept getting carried out.
are Memory Attacks
programming languages allow the execution of code that hasn’t been
compiled yet. Browser scripts and batch processing documents just
contain lists of high-level instructions. These are interpreted into
executable code at run-time.
time a web browser or command prompt comes across one of these
instructions, it suddenly converts it into mathematical code and runs
it in memory. Attackers can flood these command processors with a
great deal of bogus information so that they suddenly fail. Once they
do, they can directly inject their problem code into memory.
it’s there, it can start to relay personal information back to an
outside operator. In fact, computer experts are concerned that
there’s some possibility that an attacker could hypothetically do
anything once they’ve gained control using this fashion.
consumers now have access to tools that can prevent these attacks
that Block Memory Attacks
Once people started to ask what are memory attacks and scientists came up with an answer, the next step was to develop an effective firewall to stop them. Consumers now have access to the first firewall solution that protects memory at the application layer rather than the file system level, which ensures that applications behave exactly as intended.
