Cybersecurity expert Eugene Kaspersky reportedly has volunteered to turn over his company’s software source code to allay fears about possible ties with the Russian government. Kaspersky made the offer public at CeBIT Australia last week. Some U.S. officials have expressed concerns that Kaspersky Lab might have a close working relationship with the Russian government. Kaspersky five years ago replaced a number of high-level managers with people who had ties to Russia’s military or intelligence services, according to reports.
