URL Obfuscation Tricks That You Didn't Know Exist
Disguising malicious URL links as genuine is an old trade secret of the hackers. Though, the disguising tricks have incredibly evolved since they began. A while ago, fake links were masked by play of words that appeared genuine to unwary users and were successful in redirecting them to the sites controlled by the hackers. But with time, the awareness against phishing significantly grew which made it hard for hackers to net victims like a piece of cake--which was the case earlier.
Cybercriminals dodged the hurdle of user awareness with sophisticated obfuscation tricks. The much evolved provided the right disguise against the increasing consciousness of phishing emails. Since URL-shortener services were put in places, scammers took advantage of this service to conceal counterfeit websites.

Several URL shortening services in the market, be it: bit.ly, x.co, goo.gl, tiny.cc and much more grew in a short span of time because including regular, long URLs in a Social Media platform like Twitter was a problem. This technique soon became popular among crooks and scammers, who took the advantage of these services to conceal their malicious links and pass it on like genuine links to various users. Couple this obfuscation trick with a neatly worded email that will convince any user of its “genuineness” in no time.
You may have come across links that appear exactly like a genuine link but yet they’re from a hacker out to phish your credentials. Let’s take a look at a phishing email here.

What’s the problem you might ask: notice how, in the email font shown, "paypal" appears to end with a lowercase "l", but it’s actually an uppercase "I". This is possibly the most dangerous trick of all because the naked eye simply can’t identify the difference.
