Phishing attacks increased nearly 40 percent in the year ending August 2024, with much of that growth concentrated at a small number of new generic top-level domains (gTLDs) -- such as .shop, .top, .xyz -- that attract scammers with rock-bottom prices and no meaningful registration requirements, new research finds. Meanwhile, the nonprofit entity that oversees the domain name industry is moving forward with plans to introduce a slew of new gTLDs.

Two men have been arrested for allegedly stealing data from and extorting dozens of companies that used the cloud data storage company Snowflake, but a third suspect -- a prolific hacker known as Kiberphant0m -- remains at large and continues to publicly extort victims.
