Teams and Copilot are changing addresses: update your firewalls

Microsoft is changing the destination address of two of its most popular services: starting this month, it will redirect M365 and Teams web users to copilot.cloud.microsoft and teams.cloud.microsoft, respectively.

The Teams move is already under way, and Microsoft has now added M365 to the mix. The company announced the changes in two MessageCenter posts: MC1465764 (mirror) and MC1462915 (mirror).

Organizations using these products are advised to update their systems and documentation to ensure continued access. Microsoft has told customers to review configurations on client devices, proxies, firewalls, secure web gateways, or other enterprise network controls to confirm that users can connect to the new addresses. Companies having trouble connecting should ensure that their environment aligns with the recommended network requirements for Microsoft 365 Copilot. 

Enterprises that had been blocking the new Copilot address to prevent employees accessing their personal Microsoft accounts can use Microsoft’s TenantRestrictions control to achieve their goals instead, it said.

All redirects should be completed by early October, Microsoft said, advising companies that can’t meet the deadline to contact their account representative for help. Limited exceptions to the Teams redirect are possible until Dec. 31, 2026, but after that no further delays will be possible, it said.

Massive breach spills credentials for thousands of sensitive networks

Researchers have uncovered a massive breach of Fortinet firewalls that has given Russian-speaking attackers near-unrestricted access to some of the world’s largest and most powerful organizations, including Oracle, Chevron, Lenovo, Federal Express, a NATO defense contractor, and Fortinet itself.

Nearly 74,000 Fortinet devices from more than 21,000 IP addresses in 194 countries have been compromised and their plaintext credentials exposed online, Bob Diachenko, a security researcher and head of SecurityDiscovery.com, said online and in an interview. He said he found the data after gaining access to the attackers’ command-and-control server and other infrastructure. The exposed data also included the industry, revenue, and employee count for each compromised organization.

Exceptional scale, poor opsec

Independent researcher Kevin Beaumont reported that “almost all” of the compromised devices remained online as of Wednesday morning. He went on to say that he has confirmed with multiple organizations found in the attackers’ logs that the credentials are real and current. In many cases, once the threat actors compromised the devices, they went on to access affected organizations’ centralized authentication systems, such as Radius servers and Microsoft Active Directory. The number of compromised devices comprises roughly half of all Internet-facing Fortinet firewalls, based on polling from Shodan.
