Last week, Syniverse, an international organization that provides technology and business services for several telecommunications companies, has confirmed it had suffered a massive attack that exposed billions of text messages and hundreds of customer login credentials for years.
The telecommunication giant processes around 740 billion text messages every year, and some of its customers include major companies such as AT&T, Verizon, and T-Mobile.
