#WHATSAPP DESKTOP SECURITY ANDROID#Someone discovers a vulnerability in WhatsApp encryption on the Android application that allows another app to access and read all of a user’s chat conversations within it. Facebook pays $4 billion in cash, $12 billion in Facebook shares, and an additional $3 billion in restricted stock units granted to WhatsApp's founders. announces its acquisition of WhatsApp for US$19 billion, its largest acquisition to date. Telegram, a cloud-based instant messaging service, launches. WhatsApp changes its profit model with an annual subscription fee of $1 after a free first year. Sequoia invests another $50 million in Series B round, valuing WhatsApp at $1.5 billion. WhatsApp's user base grows to about 200 million active users and its staff to 50. The WhatsApp support staff announce that messages were encrypted in the "latest version" of the WhatsApp software for iOS and Android (but not BlackBerry, Windows Phone, and Symbian), without specifying the cryptographic method. Īn unknown hacker publishes a website that makes it possible to change the status of an arbitrary WhatsApp user, as long as the phone number was known. SnapChat, a competing photo messaging app, is founded. In Series A round, WhatsApp founders agree to take $7 million from Sequoia Capital on top of their $250,000 seed funding, after months of negotiation with Sequoia partner Jim Goetz. It eventually starts to compete with WhatsApp and becomes very popular in China. #WHATSAPP DESKTOP SECURITY FOR ANDROID#WhatsApp support for Android OS is added. īrian Acton persuades five ex-Yahoo! friends to invest $250,000 in seed funding, and is granted co-founder status. WhatsApp 2.0 is released on the App Store for the iPhone. Jan Koum incorporates WhatsApp in California. If you’re a WhatsApp user, remember that this won’t change soon.Reception and criticism of security and privacy features in the WhatsApp messaging service WhatsApp Timeline In 2018, Google researchers revealed a flaw that could have compromised a device, again via a simple call.Īrguably, the problem here isn’t WhatsApp but the complex nature of modern messaging applications coupled to the willingness of researchers (and malicious actors) to hunt for them in the world’s number one communications app.įor all its much-vaunted security features, attackers have a strong incentive to look inside the app’s guts for security holes that could undermine this. #WHATSAPP DESKTOP SECURITY INSTALL#Last May, a severe WhatsApp zero-day was being exploited by a nation state group to attempt to install spyware on targets simply by phoning them. #WHATSAPP DESKTOP SECURITY MP4#Recent incidents have included an MP4 flaw that could have led to an RCE, and another involving malicious Gifs with the same effect on Android. ![]() ![]() #WHATSAPP DESKTOP SECURITY PATCH#It’s not the first time WhatsApp’s required a patch to fix its security. Vulnerable versions of WhatsApp Desktop prior to v paired with WhatsApp for iPhone versions prior to 2.20.10. When Chromium is being updated, your Electron-based app must get updated as well, otherwise you leave your users vulnerable to serious exploits for no good reason! Other browsers such as Safari are still wide open to these vulnerabilities.Įven so, better rules in the software’s CSP would have mitigated much of the XSS, as would have updating Electron, said Weizman: Susceptible to these code injections, although newer versions of Google Chrome have protections against such JavaScript modifications. But, as PerimeterX’s summary of the research says, these are: ![]() This is a convenient way to develop web applications that also work on desktop computers. However, it could also be used to gain read permission to the local file system, that is the ability to access and open files and, potentially, for remote code execution (RCE).Īn underlying problem is that WhatsApp desktop uses older versions of Google’s Chromium framework, written using the cross-platform Electron platform. Using modified JavaScript in a specially crafted message, an attacker could exploit this to feed victims phishing and malware links in weblink previews in ways that would be invisible to the victim.Īccording to Weizman, this is probably remotely exploitable although the users would still need to click on the link for an attack to succeed. The immediate problem was caused by a gap in WhatsApp’s Content Security Policy (CSP), a security layer used to protect against common types of attack, including XSS. Patched this week as CVE-2019-18426, it’s the sort of weakness iPhone WhatsApp desktop users will be glad to see the back of. Sure enough, this week we learned that he uncovered a clutch of vulnerabilities that led him to a tasty cross-site scripting (XSS) flaw affecting WhatsApp desktop for Windows and macOS when paired with WhatsApp for iPhone. Does WhatsApp have a lot of vulnerabilities or are there simply a lot of people looking for them?Īsk PerimeterX researcher Gal Weizman, who last year set about poking the world’s most popular messaging platform to see whether he could turn up any new weaknesses. ![]()
