Protected Voices: Ransomware


Hello, my name is Jim, and I’m
a special agent with the FBI. In this video I want to help
you recognize, understand, and protect yourself from
ransomware attacks. Ransomware is a type of
cyberattack in which an adversary accesses your computer
and encrypts your data, which can cripple your campaign. Once you realize you can no
longer access your own files, the adversary demands a ransom
payment in exchange for a
decryption key. If you pay the ransom, the
promised key may or may not be provided, and it
may or may not work. If you pay the ransom once, It’s
likely they’ll come back again, infect your systems with
ransomware a second time, and ask for more money. The key to ransomware
defense is prevention. Here are some specific steps
your campaign can take to keep your data safe: Train all staff
in cyber hygiene awareness. Many ransomware attacks start
by convincing a user to take an action, such as clicking a link,
typing a password into a fake website, or downloading a file. Watch our other Protected Voices
videos for more cyber security hygiene
tips. Use a least-privilege principle. Limit users’ access to only the
parts of the computer network they actually need. If a staff member only needs to
read certain files, give him or her read-only access, and don’t
allow that user to edit the files. Before you give anyone
administrator access to files, make very sure they need
that powerful access. This least-privilege principle may help stop malware from
spreading. Back up data to a
standalone source. Ransomware spreads through a
network, so anything connected to that network when the
infection hits – including network backups – is
likely to be infected, too. Some ransomware strands can even
lock down cloud-based backups. The one best defense to
ransomware is a backup to a separate computer or hard drive
that’s disconnected from the main network after
a backup is done. It’s a good idea to periodically
check your backup to ensure it’s not corrupted. And you should also practice
restoring your data from your backup copy from time to time. Keep your anti-virus programs
up to date and patched. And don’t put off installation
of system updates that require you to restart your computer. Keep your software updated so you’re using the latest
versions. What if you do get
infected with ransomware? Call your local FBI field
office to report a problem. The FBI does not condone
paying the ransom. If you pay the ransom, you’re
encouraging the adversary to continue infecting
other victims. And even if you pay, there’s no
guarantee that you’ll regain access to your data. Remember, your voice
matters, so protect it.
