For four days this past week, Internet-of-Things giant Ubiquiti failed to respond to requests for comment on a whistleblower’s allegations that the company had massively downplayed a “catastrophic” two-month breach ending in January to save its stock price, and that Ubiquiti’s insinuation that a third-party was to blame was a fabrication.

On Jan. 11, Ubiquiti Inc. [NYSE:UI] — a major vendor of cloud-enabled Internet of Things (IoT) devices such as routers, network video recorders and security cameras — disclosed that a breach involving a third-party cloud provider had exposed customer account credentials.

A phishing attack last week gave attackers access to email and files at the California State Controller’s Office (SCO), an agency responsible for handling more than $100 billion in public funds each year. The phishers had access for more than 24 hours, and sources tell KrebsOnSecurity the intruders used that time to steal Social Security numbers and sensitive files on thousands of state workers, and to send targeted phishing messages to at least 9,000 other workers and their contacts. Continue reading Phish Leads to Breach at Calif. State Controller

SMS text messages were already the weakest link securing just about anything online, mainly because there are tens of thousands of people (many of them low-paid mobile store employees) who can be tricked or bribed into swapping control over a mobile phone number to someone else. Now we’re learning about an entire ecosystem of companies that anyone could use to silently intercept text messages intended for other mobile users. Continue reading Can We Stop Pretending SMS Is Secure Now?
