Facebook Inc., mobile messaging app, WhatsApp said it has discovered its users might be vulnerable to having malicious spyware installed on phones without their knowledge.
Facebook Inc. said in a statement that “WhatsApp encourages people to upgrade to the latest version of our app, as well as keep their mobile operating system up to date, to protect against potential targeted exploits designed to compromise information stored on mobile devices,” a spokesman said.
“We are constantly working alongside industry partners to provide the latest security enhancements to help protect our users,” he said. WhatsApp did not elaborate further.
WhatsApp informed its lead regulator in the European Union, Ireland’s Data Protection Commission (DPC), of a “serious security vulnerability” on its platform.
“The DPC understands that the vulnerability may have enabled a malicious actor to install unauthorized software and gain access to personal data on devices which have WhatsApp installed,” the regulator said in a statement.
“WhatsApp are still investigating as to whether any WhatsApp EU user data has been affected as a result of this incident,” the DPC said, adding that WhatsApp informed it of the incident late on Monday.
Reuters quoted Financial Times (FT) which reported that a vulnerability in WhatsApp allowed attackers to inject spyware on phones by ringing up targets using the app’s phone call function.
FT said the spyware was developed by Israeli cyber surveillance company NSO Group and affects both Android and iPhones. The FT said WhatsApp could not yet give an estimate for how many phones were targeted.
The FT reported that teams of engineers had worked around the clock in San Francisco and London to close the vulnerability and it began rolling out a fix to its servers on Friday last week and issued a patch for customers on Monday.
Asked about the report, NSO said its technology is licensed to authorized government agencies “for the sole purpose of fighting crime and terror,” and that it does not operate the system itself while having a rigorous licensing and vetting process.
“We investigate any credible allegations of misuse and if necessary, we take action, including shutting down the system. Under no circumstances would NSO be involved in the operating or identifying of targets of its technology, which is solely operated by intelligence and law enforcement agencies,” the company said.
WhatsApp disclosed the issue to the US Department of Justice last week, the FT said.
The latest development is coming as a kind of coincidence given the recent call by Chris Hughes, Facebook’s former co-founder who called for the breakup of the company into part citing the overbearing power of Facebook’s CEO, Mark Zuckerberg and its susceptibility for abuse. Facebook said in a reply that breaking up the company will not solve the problem of social media.
Facebook acquired WhatsApp in 2014 for $19 billion.
WhatsApp is the world’s largest mobile messaging application with over 1.5 billion monthly active users.
However, the popularity and sheer amount of data transmitted on the platform has made it prey for data thieves and other malicious intents.
For the best anti spyware, you will need to a thorough research to determine what fits your needs.
