As the digital landscape evolves, so do the tactics of cybercriminals. A new financially motivated threat actor, known as TA2900, has emerged with a focused and cunning strategy: targeting renters in France — and, more subtly, in Canada — through carefully crafted Business Email Compromise (BEC) campaigns. With urgency, deception, and a façade of legitimacy, this group is leveraging social engineering in its most manipulative form to reroute rental payments directly into attacker-controlled bank accounts.
Sophisticated Scam Targets French Renters: What We Know So Far
Over the last several months, TA2900 has initiated a wave of cyberattacks exploiting the trust between tenants and property managers. These emails, written in fluent French and designed to appear credible, claim unpaid rent issues and urge immediate action — often instructing victims to update payment details to new bank accounts.
- TA2900’s emails masquerade as property management firms or rental agencies, heightening perceived authenticity.
- Victims are told previous rent payments failed and must now use a “new” bank account, provided directly or upon request.
- These accounts are frequently rotated; researchers identified nearly two dozen unique IBANs across over 50 campaigns.
- The fraud extends to asking for proof of payment or automatic payment authorizations, deepening the attackers’ access.
- Bank accounts used are often low-cost accounts from major French banks, making them harder to flag as suspicious.
- Communication is routed through freemail providers (like Gmail or Yahoo), concealing the group’s real identity.
- Email subjects like “Loyer” (Rent) or “Nouveau RIB” (New Banking Info) are vague but effective.
- Campaigns often originate from compromised academic email accounts, likely breached through previous phishing or malware.
- Early attack variants included PDF attachments styled with fake rental firm branding, though use of such files declined by late 2024.
- Some messages display odd language or phrasing, suggesting automated translation or even AI-assisted writing, though unconfirmed.
Attribution and Motivation:
Proofpoint, a leading cybersecurity firm, attributes TA2900’s actions to financial gain, with evidence pointing to detailed knowledge of French property systems. The group exploits urgency and anxiety, using emotional manipulation to bypass skepticism. Despite the sophistication, their physical location remains unknown.
Key Indicators of Compromise (IOCs):
Proofpoint lists several suspicious email addresses tied to TA2900, many of which use domains like @gmail.com, @yahoo.com, and @outlook.fr, enhancing their plausibility to unsuspecting users.
What Undercode Say:
The emergence of TA2900 reveals a powerful convergence of psychology, social engineering, and basic financial fraud mechanisms. What sets this group apart is not merely their use of phishing — a common attack vector — but their ability to camouflage malicious intent within an ecosystem as routine as rental transactions.
The emotional levers used — fear of eviction, urgency, financial embarrassment — are timeless triggers. Combined with clean formatting, familiar branding, and the use of native French communication, TA2900’s operations evoke a deceptive professionalism. Victims feel compelled to act swiftly, abandoning standard due diligence in favor of compliance.
What’s also notable is the strategic use of compromised educational institutions as launch points for these campaigns. University or school-based email systems are inherently trusted, especially within communities or local populations. By weaponizing them, TA2900 slips under the radar of spam filters and elevates trust in the eyes of recipients.
Their approach to rotating IBANs reflects both operational discipline and adaptability — hallmarks of a serious and organized operation. Each bank account is discarded after minimal use, limiting the window in which fraud detection mechanisms can respond. The frequent refresh rate also challenges traditional anti-fraud systems that rely on pattern recognition.
The possibility of AI involvement, while still speculative, adds another layer of concern. If confirmed, it would signal a dangerous new chapter where generative AI augments cybercriminal efficiency — enabling threat actors to scale operations faster while crafting more convincing narratives in multiple languages.
TA2900’s preference for low-cost accounts at legitimate French banks hints at a savvy understanding of how to blend in. These accounts are easy to set up and rarely draw suspicion — especially when names and addresses resemble real estate entities.
Ultimately, this campaign reinforces the continued vulnerability of human decision-making in digital ecosystems. No firewall or antivirus can prevent someone from clicking “Send” when they believe they’re simply paying rent. That’s the essence of BEC fraud — it bypasses technical defenses and goes straight for human trust.
The group’s success underscores a deeper truth: education and awareness are as critical as technical protections. If individuals are trained to question sudden requests — especially those involving changes in financial protocol — then the power of campaigns like TA2900’s begins to wane.
Cybercrime isn’t always high-tech; often, it’s just high-touch. And TA2900 has mastered the subtle art of emotional manipulation in the digital age.
Fact Checker Results:
- Confirmed by Proofpoint: TA2900 is actively engaged in French-targeted BEC campaigns.
- High Confidence Attribution: Financial motivation is clearly established by researchers.
- Authenticity Tactics Verified: Language use, IBAN rotation, and compromised institutional accounts are all documented.
