for the first time to the video-call
app Zoom as the coronavirus re-
strictions upend their way of life.
But some are also making mis-
takes that could leave their priva-
cy and security at risk, and thou-
sands of Zoom video calls have
now b een l eft publicly viewable on
the open Web. Here’s how to pro-
tect your videos:- Do you need to record?
Zoom allows people to live-
stream their m eetings a nd doesn’t
store the content of those calls,
according to its privacy p olicy. B ut
a call “host,” who starts the meet-
ing, can decide to record the call,
either to save it to their own com-
puters or upload it to Zoom’s serv-
ers. Participants on a call are noti-
fied through audio and video
when a host decides to record; if
you d on’t w ant to be recorded, you
can ask the host to stop recording
or leave the call. If you’re a host,
the easiest way to protect your
videos is not to record them in the
first place. - Consider renaming the file.
When Zoom saves a video to a
host’s computer, it gives the re-
cording a default file name that a
stranger can easily predict and
then search for. If you don’t want
to give away that the file was re-
corded v ia Zoom, c onsider using a
random file name or calling it
something u nique. - Watch where you post it.
Zoom allows people to upload
recordings to online file sites run
by Amazon, Dropbox and Google,
as well as YouTube and Vimeo. If
you d on’t w ant the f ile to be public,
make sure your accounts on those
sites are set to private or protected
by a password. - These other settings can
help.
Don’t p ublicly s hare y our Zoom
“meeting I D.”
Set a password for the meeting,
then share it o nly with partici-
pants.
make sure “screen sharing” i s
set to “Host only.” That prevents
other people on the call from
abruptly blasting text or images
onto other participants’ screens.
Use the “waiting room” f eature.
It prevents new participants from
joining t he call until the host ap-
proves.
Use a “virtual background” if
you want to cover up everything
behind you.

How to
protect your
Zoom calls
redirecting its engineers to tack-
ling security flaws.
The videos could be a surprise
for people who expected their
sensitive discussions would be
kept private. But they could also
put people at real personal risk.
ruth Schwartz, the director of
Conscious Girlfriend, a relation-
ship support group for lesbian
and queer women, said she was
alarmed to learn that videos of
her group sessions could be
viewed online, including one in
which women talked about how
they recovered from toxic rela-
tionships.
Schwartz said she went back to
protect the Zoom videos and said
she was worried about groups like
hers, in which some women have
not publicly shared their sexual
orientation.
“It’s a really important wake-
up call,” s he said. “Social connec-
tion is one of the biggest predic-
tors of mental and physical
health.... It’s s o important for all
of us who do this kind of sensitive
work to take the precautions to
protect our communities.”
[email protected]Geoffrey A. Fowler contributed to this
report.er video-chat programs, such as
requiring people to use a unique
file name before saving their own
clips. That style of operating sim-
plicity has powered Zoom to be-
come the most popular video-
chat application in the United
States, but it has also frustrated
some security researchers who
believe such shortcuts can leave
users more vulnerable to hacks or
abuse.
Zoom chief executive Eric Yuan
acknowledged in a blog post
Wednesday night that the service
is being used far more extensively
than he had contemplated when
he founded the company in 2011.
“We did not design the product
with the foresight that, in a mat-
ter of weeks, every person in the
world would suddenly be work-
ing, studying, and socializing
from home,” he wrote. The sys-
tem’s new user base, he said, was
using Zoom in a number of “unex-
pected ways, presenting us with
challenges we did not anticipate
when the platform was con-
ceived.”
Yuan also apologized for Zoom
falling short of users’ “privacy and
security expectations” and said
the company would be freezing
new features for 90 days andusing a free online search engine
that scans through open cloud
storage space online. one search
for recordings, using Zoom’s de-
fault naming convention, re-
vealed more than 15,000 results.
“This was stuff I didn’t feel
good watching, and I doubt all of
the people here know these videos
are public,” he said.
many of the videos can be
found on unprotected chunks of
Amazon storage space, known as
buckets, which are widely used
across the Web. Amazon buckets
are locked down by default, but
many users make the storage
space publicly accessible either
inadvertently or to share files
with other people. (Amazon
founder and CEo Jeff Bezos owns
The Post.)
Thousands of other Zoom clips,
all of them named in the same
way, h ave been uploaded onto the
video sites YouTube and Vimeo. In
one clip posted Wednesday, a
class of second-grade students
can be seen learning about money
while logged in from home.
The problem is not exclusive to
Zoom video or Amazon storage.
But in designing their service,
Zoom’s engineers bypassed some
common security features of oth-use extreme caution and be trans-
parent with meeting participants,
giving careful consideration to
whether the meeting contains
sensitive information and to par-
ticipants’ reasonable expecta-
tions,” t he statement said.
five people identified in the
videos The Post viewed said they
had no idea how the footage made
its way online.
“That definitely shouldn’t be
happening,” said Jack Crann, the
owner of the Connecticut dog-
training company Peace of mind
Canine, after a Post r eporter alert-
ed him to a video that included
private financial details. “That
was a meeting for us, and
shouldn’t be put out for the pub-
lic.”
Patrick Jackson, the technolo-
gy chief of the privacy-software
company Disconnect and a for-
mer researcher for the National
Security Agency, who alerted The
Post to the exposed data, said
Zoom could do a better job at
cautioning people to protect their
videos. Zoom could also help by
implementing design tweaks,
such as naming videos in an un-
predictable way to make them
harder to find.
Jackson found the videos bywas published.
Zoom videos are not recorded
by default, but call hosts can
choose to record them and save to
Zoom servers or their own com-
puters without participants’ con-
sent, though participants do re-
ceive a notification when a host
starts to record.
The discovery that the videos
are openly available on the Web
adds to a string of Zoom privacy
concerns that have come to public
attention as the service has be-
come the preferred alternative for
American work, school and social
life.
The company reached more
than 200 million daily users last
month, up from 10 million in
December, as people turned on
their cameras for Zoom wed-
dings, funerals and happy hours
at a time when face-to-face gath-
erings are discouraged or banned.
Zoom said in a statement that it
“provides a safe and secure way
for hosts to store recordings” and
provides guides for how users can
enhance their call security.
“Should hosts later choose to up-
load their meeting recordings
anywhere else, we urge them to
