A Silent Threat: How Hackers Outwitted MFA Using Gmail’s Own Tools
In an alarming display of cyber espionage, hackers allegedly tied to Russia’s APT29 (also known as Cozy Bear) orchestrated a highly targeted phishing campaign against Keir Giles, a prominent British researcher and critic of Russian policies. This operation didn’t rely on brute-force tactics or malware, but on clever manipulation of a legitimate Gmail feature and patient, well-informed social engineering.
Targeted Manipulation: The Attack on Keir Giles
In early 2024, Keir Giles—senior fellow at Chatham House and expert in Russian affairs—received an email from someone impersonating a senior U.S. State Department advisor named Claudie S. Weber. The communication appeared authentic, inviting Giles to a private conversation via a “guest tenant platform,” a term that sounded plausible enough to avoid immediate suspicion.
Over the course of several weeks, Giles and the fake Weber exchanged numerous emails. The attackers maintained a professional tone, complete with PDF guides and even IT support offers, slowly building trust. Giles noticed inconsistencies but nothing concrete enough to halt communication. “They were very patient, very persistent, and incredibly well-informed,” Giles told The Times.
The turning point came when the attacker requested Giles to create an “app-specific password,” a real Gmail function intended for older applications that don’t support modern security measures like 2FA (two-factor authentication). Although this feature is legitimate, it was used deceptively to grant full access to Giles’s account—bypassing multi-factor authentication entirely.
Google confirmed that this wasn’t a Gmail vulnerability. Instead, it was a classic case of abusing a tool designed for convenience. Shane Huntley, head of Google’s Threat Analysis Group (TAG), highlighted that attackers didn’t breach Gmail’s systems but leveraged user error through careful manipulation.
The attackers had constructed convincing email addresses and even copied other officials on the correspondence. Gmail didn’t flag the addresses as suspicious, which added credibility to the communications.
Google attributed the operation to a Kremlin-backed group, warning that others in similar fields—media, academia, policy—could be targeted next. This campaign underscores a critical point in cybersecurity: technological defenses can be rendered ineffective if human trust is manipulated.
What Undercode Say: 🔍 Deep Analysis of the Incident
The New Age of Social Engineering
This attack exemplifies a new generation of cyber threats where social engineering is as dangerous as technical exploits. The attackers didn’t break through firewalls or brute-force credentials. Instead, they exploited a loophole in human judgment—a form of hacking that’s much harder to detect and defend against.
Abuse of Legitimate Features
The attack was brilliantly executed using a legitimate feature of Gmail—app-specific passwords. Designed for use with outdated apps lacking modern security capabilities, this function bypasses 2FA, opening a side door that most users (and even many IT professionals) overlook.
Google has repeatedly emphasized that these tools are safe when used correctly. However, the fact that they can be weaponized in this way shows a significant blind spot in both user education and system design.
Long-Game Strategy
What sets this phishing campaign apart is its patience and depth. Unlike mass phishing attempts that are quickly deployed and easily detectable, this operation spanned weeks. It involved layered deception, fake identities, realistic documents, and psychological manipulation. That level of sophistication is rarely used on ordinary targets—it’s typically reserved for high-value individuals like government advisors, policy analysts, or journalists.
Implications for Global Cybersecurity
This attack sends a clear message: even the most secure platforms can be compromised if users can be tricked into bypassing protections themselves. For researchers, journalists, or political commentators who deal with sensitive topics, this is a wake-up call. Cybersecurity isn’t just about having strong passwords or 2FA—it’s also about being vigilant against psychological manipulation.

The
High Stakes and Future Attacks
This wasn’t just an isolated incident. It’s likely part of a larger campaign aimed at influencing international narratives or collecting intelligence from influential voices. Experts warn that these kinds of attacks will become more common, targeting individuals who hold sway in public discourse.
How to Protect Yourself
Avoid sharing app-specific passwords unless absolutely necessary.
Verify identities using secondary channels (like calling known contacts).
Inspect email headers and metadata for inconsistencies.
Never trust documents blindly, even if they seem official.
Use hardware security keys instead of relying solely on 2FA or SMS-based authentication.
Cybersecurity is no longer just a technical domain—it requires emotional intelligence, pattern recognition, and a healthy dose of skepticism.
✅ Fact Checker Results
No technical vulnerability was found in Gmail itself.
The phishing relied on human manipulation, not software flaws.
Attack confirmed by Google’s Threat Analysis Group and linked to APT29.
🔮 Prediction
As geopolitical tensions rise, state-sponsored cyber operations will increasingly use socially engineered attacks to infiltrate the digital lives of high-profile critics, academics, and media professionals. We can expect more tailored campaigns, potentially using AI-generated personas and deeper context modeling, making future attacks even harder to detect. The line between trust and vulnerability will blur further—making digital awareness a critical skill for anyone in the public eye.
