Community Bank disclosed a security incident after customer information was exposed through use of an unauthorized AI-based software application, according to a filing with the U.S. Securities and Exchange Commission. The bank said the compromised non-public data included customer names, dates of birth, and Social Security numbers, and that it reported the matter because of the volume and sensitivity of the information involved. Reporting indicates the lapse may have occurred when customer data was uploaded to an online AI chatbot or similar service, though the bank has not identified the application or explained the exact mechanism.
The bank said the incident did not disrupt operations or prevent customers from accessing accounts or payment services, but it is still assessing the scope of affected data and notifying impacted individuals as required by law. Community Bank is also communicating with banking and financial regulators and pursuing remediation to prevent a recurrence. The number of affected customers remains undisclosed.

A misconfiguration in *Firebase* exposed nearly **300 million** private messages from roughly **25 million** users of the AI chatbot app **Chat & Ask AI**, after the app’s Firebase `Security Rules` were left publicly accessible. Reporting indicates the exposed data included full chat histories, bot names, and highly sensitive user prompts (including self-harm and potentially unlawful activity discussions); the issue was reported to developer **Codeway** by a researcher who also claimed to have identified similar inadvertent exposure across **103** other iOS apps, underscoring how common cloud-database misconfigurations remain as AI features are embedded into consumer applications. Separately, the **European Parliament** restricted lawmakers’ use of built-in AI tools on work devices, citing cybersecurity and privacy concerns about uploading confidential correspondence to external cloud services and uncertainty over how uploaded data may be stored, reused for model improvement, or accessed under non-EU legal authorities. In healthcare, ECRI Institute researchers warned that **AI chatbots** represent a leading 2026 health technology hazard due to safety, security, and privacy risks—particularly because many tools are not validated for clinical use—while also highlighting that IT outages (including those caused by cyberattacks) and legacy medical device issues remain major operational and patient-safety threats.

Community 1st Credit Union disclosed a data breach tied to **Marquis Software Solutions**, a marketing and customer-engagement vendor that reportedly serves more than 700 banks and credit unions. Reporting indicates the vendor intrusion exposed sensitive customer data held on behalf of financial institutions, with Community 1st identifying affected individuals whose information was compromised through the third-party incident rather than a direct breach of the credit union's own network. Separate breach reporting says the Marquis incident affected **more than 1.3 million people** and exposed highly sensitive personal information, including **Social Security numbers**. The disclosures highlight the scale of third-party concentration risk in the financial sector, where a compromise at a single software provider can cascade across multiple banks and credit unions and trigger customer notifications, breach filings, and potential fraud and identity-theft concerns.

Figure and Allianz Life disclosed separate breaches in which attackers used **social engineering** to gain access to systems holding large volumes of customer data. Figure said an employee was deceived into granting access, leading to the public posting of a dataset from January 2026 that contained more than **900,000 unique email addresses** as well as names, phone numbers, physical addresses, and dates of birth. Allianz Life reported that a cyberattack in July 2025 targeted data stored on **Salesforce** and was later followed by the online leak of **1.1 million unique email addresses**. The exposed Allianz Life records also included names, genders, dates of birth, phone numbers, and physical addresses, underscoring how social engineering attacks continue to drive large-scale exposure of sensitive personal information across financial services firms.
