A single weak password is believed to have allowed hackers to cripple KNP, a 158-year-old transport company in Northamptonshire, leading to its closure and the loss of 700 jobs. The ransomware attack, carried out by the cyber gang Akira, encrypted the company’s data and locked its systems, with a ransom demand estimated at £5 million—an amount the firm could not pay.

Security researchers have uncovered what may be one of the largest data breaches to date—a cache of 30 databases containing a staggering 16 billion records, according to a new report from Cybernews.
