Threat Intelligence Brief
Curated summary with source attribution
Source: blog.mornati.net
Threat Risk: Medium
Victim: French consumers and sports licensees
Incident: Targeted phishing campaigns utilizing leaked data from Cultura and the French Tennis Federation.
Impact: Potential identity theft and financial fraud targeting millions of French citizens.
Attacker: Unidentified threat actors
Analysis: Attackers are weaponizing data from the Cultura and French Tennis Federation breaches to launch targeted phishing campaigns. By abusing SendGrid’s API, the actors bypass standard SPF and DKIM filters, making the fraudulent emails appear legitimate. The presence of geopod-ismtpd in email headers serves as a technical indicator of this specific abuse pattern.
Recommendations: Adopt unique email aliases for every online service to isolate and identify the source of leaks.; Inspect email headers for geopod-ismtpd hostnames in unexpected payment or health-related correspondence.; Report SendGrid API abuse to the provider to help dismantle the attackers’ delivery infrastructure.
