Spam using WhatsApp voice mail

      I wrote before about various tricks that cybercriminals use to attract people to do something (btw, this is called “social engineering”). This time, they make use of the well-known WhatsApp (written like I did and not like in the screenshot below) to redirect users to an online pharmacy website.     The funny thing is that the link behind the button “autoplay” goes to an IP address hosting a file with extension PL (coming from Perl) which means usually a script. The file contains just minimal JS code to redirect to the pharmacy page. The email pretends to come from Whats App Reminder <billing@shapeupsf.org> which has nothing to do with WhatsApp. Of course, if you look in the headers, you see that the email address is spoofed.     What do we learn from here? 1. Always have a look at the sender and the recipient 2. Don’t ignore the small things like “WhatsApp” vs. “Whats App”. Usually the fraudsters don’t pay attention to details. You should. 3. Have a look where you click. The link behind the button should be inside the official domain (like whatsapp.com) and not to some strange server.

Facebook, WhatsApp and the new Internet bubble

I was reading the great news about the 19 billion USD which Facebook paid for WhatsApp. I want to underline, that 1 year ago, Google wanted to buy it for… 1 billion USD: http://venturebeat.com/2013/04/08/as-google-acquisition-rumors-grow-is-whatsapp-really-worth-a-billion-dollars/ And in December 2013, http://blogs.wsj.com/digits/2013/12/19/whatsapp-hits-400-million-users-wants-to-stay-independent/ WhatsApp has “no plans to sell, IPO, exit, [get new] funding,” Koum said. “Despite the fact that we’re able to monetize today, we’re not focused on monetization,” Koum said. “We view monetization as five, 10 years down the road. We’re trying to build a sustainable company that’s here for the next 100 years.” Koum said WhatsApp has attracted new users without spending on marketing.   I found some articles which say something like: The huge price tag attached to Facebook’s purchase of WhatsApp — one of the largest web deals in history — actually makes more sense than you might think at first glance.   What? No company is so much worth! And especially not an instant messaging company. Some facts:(read here the details). – the company is 5 years old – it has 450 million users. – It has 400 Million active monthly users   – July 2013 it had 200 million active monthly users – 100 M from them joined in the last…
