Rumble v1.14

A new release of Rumble is live with user interface updates, security improvements, and a host of new fingerprints that include mDNS replies and TLS JARM hashes. Read on for the full list of changes since v1.13.

User Experience Updates

  • Autocompletion is now available for Inventory search terms and the keywords have been revised to be more consistent. The older keywords will be gradually phased out as the search interface evolves.

  • Autocompletion is now available for asset tags using the top 50 most-used tags within the organization. This works from the asset details page as well as when applying tags from the Inventory view. The top 50 asset tags are now also available in the dashboard as a new column.

  • Subnet tags that apply to a given asset are now displayed in the Inventory table view, alongside the asset-specific tags. In addition, the asset details page now shows the subnet tags (if any) in the upper left section. The asset details page also received a light update to improve readability.

  • Breadcrumbs at the top of each page are now clickable and the page titles have been simplified.

  • The Subnet Grid report is now faster and supports RTT, TTL, and Age color modes.

  • CSV exports of the Services Inventory are now significantly faster.

  • Scan speed is now listed in the task details page.

Security Improvements

The Account link in the sidebar now directs superusers to an Account Settings page with new security-related settings:

  • Require multi-factor authentication for all users will force all users to enable a MFA security token in order to use the platform.

  • Disable support access to your account can prevent Rumble support staff from having access to your account via our internal support console.

  • Maximum idle session time lets you force web sessions to be logged out if there has been no activity for a certain number of minutes.

  • Maximum login duration lets you force users to re-authenticate at least once every so many hours.

These options apply to all organizations and users associated with your billing account.

Agent communication to the Rumble cloud is now limited to two IPv4 addresses (13.248.161.247, 76.223.34.198) and a single hostname (console.rumble.run). This simplifies firewall rules for networks with strict egress policies.

In addition to the changes above, the platform received a number of security fixes and additional hardening as part of our most recent security audit.

Fingerprints & Scanning

  • Rumble now has support for JARM scanning. The JARM fingerprints will appear in TLS service details under the tls.jarm key. A new entry has been added to the Query Library for JARM hashes associated with malicious software. Rumble now uses JARM hashes for device fingerprinting.

  • mDNS (Bonjour/ZeroConf) fingerprint support has been expanded to cover additional response types. New mDNS fingerprints include coverage for recently released Apple hardware and many popular HomeKit devices.

  • The scan engine is now more reliable on Macintosh computers running macOS 11 Big Sur.

  • SMB fingerprinting has been improved for devices that support both SMBv1 and SMBv2.

  • Rumble now avoids even more bogus service replies automatically.

  • BACnet scans now support the use of multiple port numbers.
