HOW TO TRUST
APPLICATIONS
DOWNLOADED ONLINE
SUSAN.ONE
Susan.one
Today, almost all the applications on your computer
are downloaded from the Internet. This gives
cybercriminals a chance to obtain the source code of
an executable file, for instance, insert malware into it,
and allow the program to be found and downloaded
online. Any user downloading and installing this file
would fall victim to the malware.
To prevent this, your operating system does not allow
the installation to proceed without checking for the
existence of a code signing certificate. In the case of
a missing certificate from a recognized vendor, the
user is alerted to this, and can then choose to proceed
with the installation or not.
However, users often do not delve into the messages
displayed with sufficient severity and may damage
the data on their computer with infected software.
Validating Susan.one application
Most consumer operating systems are pre-configured
to check for the presence of a code-signing certificate
before an application is installed.
When an installation is prompted, the OS first
confirms the legitimacy of the certificate and when
the certificate does not exist or it's not issued by the
recognized vendor, OS informs you that the
application is not from a trusted source.
In fact, you can verify the validity of the software quite
easily before you install it. On Windows OS make
right-click on the executable file and choose
"Properties" from the menu.
In the properties window, navigate to the "Digital
Signatures" tab and from there you can see the list of
the signatures. In Susan.one case, there must be
signature signed by Susan.one Ventures.
Click on the "Details" button to investigate signature
information. This window will display signer
information and reports, is signature ok or not.
Now you can look certificate information by clicking
to "View Certificate" button. If you see the same
information as in the image below, you can be sure
that the application was released by Susan.one and
has not been altered in any way since the release.
Summary
There is inevitably a risk associated with software
downloaded from the Internet if you cannot be sure
that the software is from the manufacturer and has
not been modified by third parties. This method
described in this article will help you identify the
source of each software and reduce the potential
damage to your computer.
However, it doesn’t mean that digitally signed
software is one hundred percent bulletproof. There
have been cases, where malware implanted in signed
software too by stealing the certificates or private
keys. But these are rather rare cases, as
manufacturers protect their private keys and
certificates very carefully, as do we.
