The hacktivist group SEA has taken a swing at Viber, the instant-messaging and VoIP service, defacing its online support center on Tuesday.
Hackers claimed credit for this act with a blue banner that reads â€œHacked by Syrian Electronic Army,â€ and displayed a message asking users to get rid of the service for privacy concerns.
â€œAfter we gain[ed] access to some systems of that app, it was clear for us that the purpose of this app is spying and tracking of its users,â€ the Syrian Electronic Army wroteÂ on their website.
Viber said the attack was possible because an employee fell victim to a phishing e-mail, in a manner that resembles their previous attack against the Onion. Apparently hackers managed to access a customer support panel and a support administration system but no sensitive data was accessed, despite hackers’ claim of having accessed â€œphone numbers and contacts and their emailsâ€ implying both clients and employees.
On Monday, the Syrian Electronic Army published 1.5 TB worth of user conversations exfiltrated from the Tango instant messenger application for mobile phones.
