DEBULL Tooling Abuses Microsoft Device-Code Flow to Target M365 Accounts

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. "The campaign did not depend on a fake Microsoft password page. This piece sits on 1 source layers, but the real value is showing why the story should not be skimmed past too quickly.

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. "The campaign did not depend on a fake Microsoft password page. The activity is assessed to share "strong" overlaps with a campaign documented by Microsoft in February 2025 under the moniker Storm-2372 , including the use of messaging or Teams-style lures to trick unsuspecting victims into entering an attacker-provided device code, along with their credentials, effectively allowing the threat actor to recover the token and hijack their account. The Hacker News is the main source layer for now, and the rest should be read as a signal that is still widening. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use.

What is happening now

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. The Hacker News form the main source layer behind the core facts in this piece. This is still a developing thread, so the useful part is knowing which source signals are hardening and which ones still need caution. With devices, practical impact usually shows up in battery life, heat, stability, and long-term usability rather than in a few flashy headline numbers.

Where the sources line up

The Hacker News is the main source layer for now, and the rest should be read as a signal that is still widening. "The campaign did not depend on a fake Microsoft password page. The Hacker News form the main source layer behind the core facts in this piece. With devices, practical impact usually shows up in battery life, heat, stability, and long-term usability rather than in a few flashy headline numbers. The readers who should care most are the ones planning to replace a device, buy an accessory, or upgrade a work setup in the next few months.

The details worth keeping

The activity is assessed to share "strong" overlaps with a campaign documented by Microsoft in February 2025 under the moniker Storm-2372 , including the use of messaging or Teams-style lures to trick unsuspecting victims into entering an attacker-provided device code, along with their credentials, effectively allowing the threat actor to recover the token and hijack their account. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use.

Why this matters most

The signal is strong enough to deserve attention, but it still needs to be read as something developing rather than fully settled. With 1 source layers on the table, the part worth reading most closely is where firm facts meet the market's early reaction. Despite these similarities, it's assessed that the threat actors are employing Storm-2372-style tradecraft through what has been described as a reusable tooling layer called DEBULL .

What to watch next

The next readout is price, device coverage, and whether the change feels real once the hardware reaches users. Patrick Tech Media will keep checking rollout speed, user reaction, and how The Hacker News update the next pieces. From 1 early signals, the piece keeps 1 references that are useful for locking the main details in place. That is why the useful reading move is not to stop at the headline, but to compare the promise, the workflow change, and the likely cost before deciding anything.
