It appears that Viber Media has been hacked by the SEA.
The defacement on the site’s support page reads:
Dear All Viber Users,
The Israeli-based “Viber” is spying and tracking you
We weren’t able to hack all Viber systems, but most of it is designed for spying and tracking
A screenshot, displayed on the support subdomain of Viber, displays users’ phone numbers, UDID, IP addresses, and system information. All unredacted.
Eleven names, email addresses, and phone numbers of individuals reported to be Viber administrators, were also posted on the defaced page.
To my knowledge, Viber, which claims to have over 200 million users for its free calls, text and picture sharing, has not yet confirmed or denied the alleged hack.
UPDATE: Viber denies some of the SEA’s claims. In a statement to TechCrunch, they write:
Today the Viber Support site was defaced after a Viber employee unfortunately fell victim to an email phishing attack. The phishing attack allowed access to two minor systems: a customer support panel and a support administration system. Information from one of these systems was posted on the defaced page.
It is very important to emphasize that no sensitive user data was exposed and that Viber’s databases were not “hacked”. Sensitive, private user information is kept in a secure system that cannot be accessed through this type of attack and is not part of our support system.
We take this incident very seriously and we are working right now to return the support site to full service for our users. Additionally, we want to assure all of our users that we are reviewing all of our policies to make sure that no such incident is repeated in the future.
