FBI sounds alarm on phishing tool that steals Microsoft 365 accounts | Latest Tech News
The FBI is warning that a new hacking platform is permitting cybercriminals to hijack Microsoft 365 accounts — including Outlook, Teams and OneDrive — while bypassing multi-factor authentication completely.
The bureau posted a public service announcement last week sounding the alarm about the “Phishing-as-a-Service” toolkit identified as Kali365, which is getting used to steal Microsoft 365 access tokens and gain entry to sufferer accounts without intercepting passwords.
The feds say that Kali365 makes it straightforward for even novice hackers to run superior phishing scams that used to require critical technical expertise.

“Kali365 lowers the barrier of entry, providing less-technical attackers access to AI-generated phishing lures, automated campaign templates, real-time targeted individual/entity tracking dashboards, and OAuth token capture capabilities,” the FBI warned.
The scheme exploits Microsoft’s reliable OAuth 2.0 “device code” authentication system — a function generally used to log into good TVs, streaming devices and other {hardware} with restricted keyboards.
Rather than stealing passwords instantly, attackers trick victims into getting into a code on a real Microsoft login web page, unknowingly authorizing the hacker’s gadget.
“The device code flow is a legitimate authentication method that is being actively exploited by cybercriminals to bypass multi-factor authentication,” the FBI said in its advisory.
“By tricking users into entering a device code on a legitimate Microsoft page, attackers can gain persistent access to accounts without ever needing the user’s credentials.”
Victims obtain phishing emails impersonating companies like SharePoint, OneDrive or Microsoft Teams.

The emails instruct targets to go to Microsoft’s reliable gadget login web page and enter a short-lived authentication code.
Once the sufferer completes the method and passes MFA checks, Microsoft points legitimate OAuth access and refresh tokens instantly to the attacker.
That permits hackers to access Outlook inboxes, Teams accounts and cloud-stored recordsdata without ever needing the sufferer’s password again.
The FBI warned that attackers can keep persistent access to accounts until the stolen tokens are manually revoked.
Matt Burk, chief info security officer at Bespoke Concierge MD, told The Post the assaults have change into more and more efficient because Microsoft’s widespread enforcement of multi-factor authentication has compelled cybercriminals to adapt.

“Since Microsoft has globally enforced MFA, this method of cyber attack is designed to bypass MFA and the need for a password,” he said.
Asked which industries or staff are most weak, Burk warned that just about anybody utilizing Microsoft 365 could possibly be focused.
“I absolutely hate to generalize, but everyone from a small mom-and-pop business to a large Fortune 500 company,” he said.
Burk added that organizations ought to deploy third-party Security Information and Event Management, or SIEM, systems succesful of detecting suspicious authentication exercise tied to token theft.
“Using these tools can detect access like the Kali365 exploit and with the correct security features can automatically shut down the connection,” he said.
Ordinary customers ought to take the menace significantly because the assaults goal cloud-based computing platforms used daily by companies and customers alike, according to the knowledgeable.
“Everybody should be concerned with this exploit,” Burk said.
Cybersecurity researchers say the emergence of Kali365 marks a major escalation in the growing “phishing-as-a-service” underground financial system, where refined assault instruments are offered to low-skilled criminals via subscription companies on Telegram and darkish web boards.
The bureau said Kali365 was first noticed last month and has quickly unfold among cybercriminal teams.
The platform automates phishing campaigns and supplies dashboards that permit attackers to monitor victims in real time.
Federal authorities said the operation is a component of a broader wave of assaults concentrating on Microsoft 365 environments globally.
Scattered Spider, also identified as Octo Tempest, is a infamous English-speaking cybercrime group identified for aggressive social engineering and SIM-swapping assaults concentrating on large companies.
Another entity, Storm-2949, has centered on compromising IT directors and senior executives through abuse of Microsoft password reset systems and cloud authentication instruments.
The Post has sought remark from Microsoft.
