Cyber Briefing: 2026.05.25
Critical data exposures in messaging apps and franchisee networks, combined with the professionalization of money laundering and digital piracy, continue to challenge global regulatory and corporate..
Welcome to Cyber Briefing, your daily source for all things cybersecurity. We bring you the latest advisories, alerts, incidents, and news every weekday.
Recent disclosures highlight significant vulnerabilities in popular communication platforms and the industrialization of financial crime. Security researchers found that WhatsApp stores chat histories in unencrypted plaintext on macOS and iOS, potentially allowing other apps within the same ecosystem to access private data. Simultaneously, the rise of Mule-as-a-Service (MaaS) on Telegram is streamlining money laundering, as cybercriminals trade verified bank and fintech accounts to bypass fraud detection. On the corporate front, 7-Eleven is currently investigating a data breach involving unauthorized access to franchisee information, emphasizing the persistent risk to internal supply chain data.
Global authorities and industry leaders are also taking decisive action against digital piracy and maritime vulnerabilities. A massive European law enforcement operation successfully dismantled CINEMAGOAL, a piracy app that caused roughly €300 million in damages; notably, authorities are now targeting both distributors and end-users with significant fines. To bolster infrastructure security, Cydome and Rakuten Maritime have partnered to deploy specialized cybersecurity technology for vessels, moving beyond basic firewalls. Additionally, the launch of the Security Masters Society marks a new effort to close the industry knowledge gap through specialized information security education.

WhatsApp Chat Histories Exposed in Unencrypted Storage
Security researchers at Mysk discovered that WhatsApp stores chat histories in unencrypted plaintext within shared app group containers on macOS and iOS devices. These message databases are accessible to other applications within the same developer ecosystem, potentially exposing private conversations. Users concerned about data privacy should be aware that their WhatsApp messages may not have the same level of protection at rest as they do in transit, despite the app’s end-to-end encryption for message transmission.

These operations have evolved into structured Mule-as-a-Service (MaaS) ecosystems that allow attackers to outsource financial laundering activities. Financial institutions and fintech companies face increased risk as criminals gain access to pre-verified accounts that can bypass standard fraud detection systems. Read More
