MOSCOW (CBS SF/AP) — Ukrainian police say they have uncovered a ring of computer hackers responsible for cyberattacks that included targeting personal data and financial records at the Stanford University Medical School and the University of California. Six members of the gang, known as Cl0p, were arrested and a number of computers, cars and about $185,000 in cash was seized. The hackers also allegedly attacked four South Korean companies in 2019 with an encryption virus that blocked internal servers and employees’ computers.
