After Optus, SingTel-owned Australian firm Dialog faces a cyberattack

Dialog, a technology consulting company owned by Singapore Telecommunications (SingTel), has reportedly suffered a data breach, worsening the corporation's data-security crisis in the aftermath of the massive data theft at Optus, the mobile phone operator.

As per a Dialog statement released by SingTel on Monday, Dialog, which SingTel purchased earlier this year, a hack may have revealed data of less than 20 clients and 1,000 current and former employees.

On October 7, Dialog discovered that a very small portion of its data, including identifying information about individual employees, had been made public on the so-called Dark Web. The actual incident happened on September 10, nearly a month earlier.

Questions about cybersecurity throughout the entire group, the promptness of breach reporting, and whether the Singapore owner is being purposefully targeted are raised by this second intrusion of a SingTel-owned company.

Optus, a SingTel business in Australia, disclosed last month that one of the largest-ever breaches in the nation had exposed information on 9.8 million former and present customers as a result of a significant security breach.

Identity document numbers belonging to more than 2 million individuals were stolen, raising worries about widespread financial theft.

In March, NCS, a SingTel subsidiary, announced that it will buy Dialog for A$325 million ($205 million).

According to SingTel, there is no proof that the two recent hacking incidents are connected, and Dialog's systems are totally separate from those of SingTel, NCS, as well as Optus.

Some of Australia's largest and most well-known firms are among Dialog's clients, according to the company's website. They consist of Virgin Australia Airlines, National Australia Bank, and various state and federal government agencies.

The hacks pose a risk of becoming a pricy lapse for the Singapore firm.

According to certain estimates, the overall costs, which include bills and fines, may reach millions of dollars. Optus has already been paying for replacement passports as well as driver's licenses.
