A massive phishing operation dubbed AccountDumpling that has compromised more than 30,000 Facebook accounts worldwide.

This is a good example of why email authentication alone is not a guarantee of safety.
What this means
If the report is accurate, the important point is not that Google itself was “hacked,” but that attackers may be abusing a legitimate service to send messages that pass SPF, DKIM, and DMARC.
That can make the email look more trustworthy to:
- Mail providers
- Security filters
- End users
So a message can be technically authenticated and still be part of a phishing attempt.
Why this matters
Many people treat SPF, DKIM, and DMARC as if they prove an email is safe. They do not. In general, they only help verify that the message was authorized to come from the sending domain or infrastructure.
They do not confirm:
- That the content is legitimate
- That the sender’s intent is benign
- That the linked page is safe
- That the brand being referenced is genuine
That distinction is very important in modern phishing campaigns.
Likely attacker advantage
Using a trusted platform can help attackers:
- Avoid some reputation-based filtering
- Increase delivery success
- Make messages look more convincing
- Reduce obvious indicators such as suspicious sender domains
This is similar in principle to abuse of services such as Google Forms, Microsoft 365, Dropbox, or other cloud platforms for phishing delivery or hosting.
Practical takeaway
The safe takeaway for users and admins is:
- Do not rely on SPF/DKIM/DMARC results alone
- Inspect the actual context of the message
- Be cautious with links related to account recovery, policy violations, or urgent security alerts
- Use MFA on Facebook and email accounts
- Verify alerts by opening the service directly in a browser instead of clicking the email link
For defenders, this reinforces the need for layered detection, including:
- Content analysis
- Link analysis
- Behavioral detection
- User awareness training
One caution about the article
I cannot verify the full technical details of the campaign from that excerpt alone, so I would treat the write-up as a report that still benefits from corroboration from Guardio Labs directly or from additional independent research.
Conclusion
A phishing email can be fully authenticated and still be malicious. Email authentication helps validate delivery legitimacy, not trustworthiness of the message content.
