A second Australian business owned by Singapore Telecommunications Ltd. was found to have suffered a cyberattack, compounding the data-security crisis at the company amid the huge data breach at mobile-phone operator Optus.
A hack on technology consulting company Dialog, which SingTel bought earlier this year, may have seen data on fewer than 20 clients and 1,000 current and former staff accessed, according to a Dialog statement issued by SingTel on Monday. Dialog discovered on Oct. 7 that a “very small sample” of its data, including personal employee information, had been published on the so-called Dark Web. The attack itself took place almost a month earlier, on Sept. 10, Dialog said Monday.
