A security flaw in DJI Romo robot vacuums allowed unauthorized access to thousands of devices after a user reverse-engineered the device-to-cloud protocol to build a custom controller app. By obtaining the private token for their own vacuum, the researcher reported they could access backend servers across regions and inadvertently gained control of roughly 6,700 vacuums, with potential access to floor plans, live camera/microphone feeds, and remote control functions; DJI issued server-side/firmware updates that required no user action, though the researcher reported at least two issues remained (including video streaming without a PIN and another undisclosed high-severity problem). Separately, mobile security researchers reported that popular Android mental health apps (about 14.7M installs across ten apps) contained 1,575 vulnerabilities—mostly low/medium severity but including 54 high-severity findings—creating risk of exposure of sensitive therapy data via issues such as credential interception, notification spoofing, HTML injection, and user location leakage.
Optimizely also confirmed a data breach following a vishing (voice-phishing) attack that provided attackers access to some internal systems and resulted in theft of basic business contact information from internal business systems/CRM and limited back-office documents; the company said attackers could not escalate privileges, install software, or establish backdoors, and it reported no evidence of access to sensitive customer data beyond contact details. While the Optimizely incident is distinct from the consumer-device and mobile-app vulnerability disclosures, it reinforces the operational risk of social engineering and the likelihood of follow-on phishing using stolen contact data.

4 events from the most recent confirmed update back to the earliest known activity.
By late February 2026, Oversecured had privately notified affected vendors about the vulnerabilities in the 10 Android mental health apps while withholding app names during coordinated disclosure. Public reporting said remediation status was still unclear and that the apps collectively had more than 14.7 million installs.
After Azdoufal reported the vacuum access issue, DJI deployed updates that remediated the flaw without requiring user action. The researcher said some problems still remained, including the ability to stream video without a security PIN and another undisclosed severe issue.
While reverse engineering his own DJI Romo robot vacuum to control it with a PlayStation controller, Sammy Azdoufal uncovered a security flaw that exposed access to roughly 6,700 vacuums worldwide. The issue allowed retrieval of floor plans, access to live camera and microphone feeds, and remote control of devices across regions including the U.S., Europe, and China.
On January 22–23, 2026, mobile security firm Oversecured analyzed 10 popular Android mental health apps from Google Play and identified 1,575 vulnerabilities, including dozens of high-severity issues. The flaws affected areas such as local storage, authentication, inter-app communication, encryption, and backend connectivity, with potential exposure of sensitive therapy and medical data.
