The infamous hacktivist group, Anonymous Collective, has claimed responsibility for a cyberattack that allegedly brought down Cosmote, Greece’s largest mobile network operator. As of now, details regarding the extent of the Cosmote cyberattack, any stolen data, or the motives behind the assault remain undisclosed.
The Cyber Express Team (TCE) has attempted to verify the claim by reaching out to official sources, but an official response is still pending.
One striking aspect that has heightened concerns is the inaccessibility of Cosmote’s official website. Attempts to access the site have proven futile, prompting questions about the veracity of the Anonymous Collective’s claim.
Confirmation or denial of the Cosmote cyberattack can only be ascertained once an official response is received from Cosmote.
Cosmote Cyberattack Recalling Past Breaches
This recent cyber incident revives memories of a significant data breach in 2020, where Cosmote faced severe consequences for failing to protect a file containing the call histories of thousands of customers.
The company was slapped with a hefty fine of €6 million (US$6.9 million) in 2022, for this security lapse. Additionally, OTE, a parent company of Cosmote, received a penalty of €3.25 million (U.S. $3.7 million) for not having the necessary security infrastructure to prevent the breach.
The 2020 breach, which occurred in September, resulted in the compromise of sensitive customer information, including phone numbers, call records, customer age and gender details, and subscriber mobile tariff plans.
Fortunately, the breached file did not contain contents of calls or messages, customer names or addresses, passwords, or any information related to credit cards and bank accounts.
Given the previous security lapses and the sensitivity of the data involved, the recent cyberattack raises serious concerns about the overall cybersecurity posture of Cosmote. Users are anxiously awaiting an official response from the company to understand the nature and scope of the current breach.
As the story unfolds, the tech community and the public will be closely monitoring the developments surrounding this major cybersecurity incident.
