MailGuard is intercepting a new wave of phishing emails spoofing OneDrive to lure users into revealing their login credentials. This simple yet deceptive scam highlights the persistent threat of credential harvesting attacks that continue to bypass standard email defences.
Disguised as a Shared Document
This campaign is built on a clean HTML email that claims to share a document via OneDrive. The message appears to come from a legitimate sender, using a subject line such as “You received Contract Form 6122025\_2JD01,” and urges the recipient to click a button to "View Document".
Here’s an example of one of the emails 👇
Despite referencing Microsoft’s OneDrive service, the embedded link leads to a phishing page that impersonates an Adobe login portal. This page is designed to capture email credentials through a two-step deception process.
The Deceptive Flow
Initial Login Attempt
Victims are prompted to enter their username and password to access the shared file.
Credential Harvesting
The first login attempt always results in an error message: "User credentials do not match. Try again!" This encourages users to re-enter their details, which are then captured by the attackers.
After the second submission, users are redirected to the official Adobe site at www.adobe.com/acrobat/pdf-reader.html to complete the illusion of legitimacy.
This multi-step trick is a classic credential phishing tactic, designed to evade suspicion and deepen the false sense of authenticity.
Subject Lines and Sender Patterns
The scam emails are being sent from compromised or spoofed email addresses using the domain “@preferred-press.com”. The display name varies but often uses the format: `Notification From [CustomerName]`.
Common Subject Lines
There are quite a few subject variations but most have "6122025_2JD01" in them:
- A share document via Onedrive
- A share file via Contract Form 6122025_2JD01
- A share file via Onedrive
- A share file via PO 6122025
- A share file via PO 6122025_2JD01
- Contract Form 6165025_2JD01
- PO 6122025
- PO 6165025_2JD01
- received a share document via Onedrive
- received a share file via Onedrive
- You received a share document via Onedrive
- You received a share file via Onedrive
- You received Contract Form 6122025_2JD01
- You received PO 6122025
- You received PO 6122025_2JD01
This level of variation is a hallmark of phishing campaigns attempting to evade pattern-based filters.
Why This Scam Is Dangerous
These emails do not contain malware attachments. Instead, they rely on social engineering and impersonation to trick users into giving up their credentials. Once compromised, those credentials can be used to access corporate email systems, launch further spear phishing campaigns, or exfiltrate sensitive business data.
These types of scams can cause reputational damage, data breaches, and financial loss — particularly when one compromised account provides access to broader systems or customer records.
Stay Safe - Know the Signs
MailGuard advises all recipients of these emails to delete them immediately without clicking on any links. Responding or providing personal details can lead to identity theft, data breaches, and financial losses.
Avoid emails that:
- Aren’t addressed to you personally.
- Are unexpected and urge immediate action.
- Contain poor grammar or miss crucial identifying details.
- Direct you to a suspicious URL that isn’t associated with the genuine company.
