WhatsApp Messenger is an instant messaging subscription service. In addition to text messaging, users can send each other images, video and audio media messages, as well as location data. As of September 2014, WhatsApp is the most popular global messaging app, with 600 million users. Aside from regular users, more underground communities like to use this application. WhatsApp activity is more complicated to monitor by a third party than regular phone messages and some online services. WhatsApp has proven to be a fast, reliable and inexpensive service for sharing various kinds of information.
The cyber underground is also seeking new platforms for chatting and sharing information. Lately, we have identified an increasing number of hacker-affiliated groups using WhatsApp services. These groups offer members chat services, hacking tips, cyberattack coordination and more. Members from numerous countries, including Bangladesh, Pakistan, Indonesia and others, expose their phone numbers to connect to such groups.
There are several manuals describing how to access other WhatsApp accounts. One post shared two different methodologies to do just that: spoofing with the help of Mac number, and using spy software. This post received over 738,000 views over a two-week period.
In addition to spy methodology, you can find various tools, such as WhatsApp Hack Spy Tool, WhatsAppSniffer, WhatsApp Xtract, WhatsApp Conversation SPY Hack Tool and more. You can also use third party spyware. These tools can be used for Android, iPhone and BlackBerry devices. Tools provide such features as tracking all voice notes, viewing all user chat logs, updating profile pictures, sending messages to contacts, changing profile status and more, depending on the tool.
The dissemination of such tools is becoming common also on social networks, such as Facebook, Twitter and LinkedIn. A Facebook page titled “WhatsApp Hack Spy Tool” has 390 members, mostly from India, Italy, France and the U.S. This page also has a related Twitter account with more than 3,500 followers. Another Facebook page titled “WhatsApp Hack Sniffer Spy Tool” has over 13,500 members, mostly from Turkey and India. Furthermore, advertisement for the tool can also be found on LinkedIn.
In addition to the free tools, you can purchase more unique software, such as a tool for hacking WhatsApp, only ten copies of which were released for sale on the DarkNet for 0.0305 BTC.
The use of WhatsApp by hacktivist communities, together with the development of hacking tools and methodologies, has opened up a new platform for the cyber community. These two directions provide a fast, inexpensive and more secure way for hacktivists to interact, coordinate operations, and exchange information and mobile hacking techniques and data vulnerabilities.
