Data Breach at Wyze Labs Exposes Information of 2.4 Million Customers

Last week, Wyze, a cost-effective home-security system company, experienced a large-scale breach impacting 2.4 million customers. Cybersecurity consulting firm Twelve Security notified Wyze about the breach, stating that Wi-Fi network details and email addresses of customers had been exposed for a total of 23 days. The unsecured database was connected to an Elasticsearch cluster from December 4, 2019, to December 27, 2019.

Wyze placed the cause of the data leak on an employee mistake that persisted due to a lack of security protocol enforcement. A new employee created a “flexible database to quickly pull user analytics, such as camera connectivity rates, user growth and the number of devices connected per user,” however, (s)he didn’t configure the proper security protocols on the database.

Wyze sent an email out Tuesday morning to its customers with further information about the breach and what actions the security company will take to protect its customers in the future.

US Coast Guard Discloses Ryuk  Ransomware Infection at Maritime Facility

The US Coast Guard (USCG) recently experienced a Ryuk ransomware attack, causing the organization to go offline for more than 30 hours.

Thankfully, no financial information was taken as only the communication systems were impacted by the hack.
