Webex
Webex is Cisco’s app for video meetings, phone calls, messaging and sharing files or your screen. It’s made by Cisco, based in the United States.
Criminals have used its name in fake downloads or scams, so get it only from webex.com.
What it is
Webex lets people join video meetings, make calls, exchange messages and share files. Cisco also distributes an older, separate Webex Meetings app, so different Webex names and identifiers can appear on a Mac.
With permission, it can use your camera and microphone for calls and capture your screen for sharing. Accessibility access lets another participant control your mouse during an agreed remote control session.
Cisco supplies official Mac downloads and automatic updates. Criminals have distributed fake Webex installers. Use Cisco’s download page to obtain the app.
Who makes it
Cisco is a US technology company with more than 40 years of history in networking, security and communications. Its legal name is Cisco Systems, Inc.. Its website is cisco.com.
Cisco makes other software with flaws that attackers have used. Its page in Companies lists them.
Is it the real one?
Every Mac app carries a signature from the developer who made it. Apple checks who the developer is before handing out the certificate, and macOS refuses to open an app whose signature has been tampered with.
HARD hasn’t yet recorded the signature on a real copy of Webex. Its Mac app shows who signed the copy you have.
Its bundle ID, the name macOS knows it by, is Cisco-Systems.Spark or com.webex.meetingmanager or com.cisco.webexmeetingsapp. Download it only from webex.com, not from an ad or a link someone sends you.
Fakes. In July 2026, Breachroad reported a recruitment scam that directed a Mac user to a fake Webex website. Its downloaded disk image instructed the user to drag an item into Terminal, leading to malware installation.
What it connects to
In normal use, Webex talks to these places on the internet. A firewall that asks before apps connect, like the one in HARD’s Mac app, will show them.

Security record
Problems with Webex or Cisco in the last three years, newest first. Keeping the app up to date covers the ones that were fixed.
| When | What happened | Source |
|---|---|---|
| A critical Webex cloud sign-in flaw could let attackers impersonate users in organisations using certain certificate settings; Cisco fixed it and required affected administrators to upload a new identity provider certificate. | ↗ | |
| A certificate checking flaw could let an attacker on a nearby network interrupt someone joining a meeting and join as that person; Cisco fixed the cloud service without requiring user action. | ↗ | |
| A flaw affecting Webex App on all operating systems could let a malicious meeting link and subsequent download lead to commands running on the user’s computer; Cisco released software fixes. | ↗ | |
| A Webex App flaw could expose session tokens to an attacker able to observe network traffic; Cisco fixed it through the cloud service without requiring user action. | ↗ | |
| Cisco disclosed unauthorised access to some customers’ meeting information and metadata during security research; fixes had been applied worldwide by 28 May 2024. | ↗ |
