August 3rd, 2018 | By Jscrambler | 3 min read

Las Vegas is eagerly awaiting the world’s leading security companies and professionals for Black Hat USA 2018 (and, as you probably know, we’ll be there!). But that’s not nearly the end of it.

As has become a tradition, Black Hat USA is immediately followed by another gigantic conference — DEF CON, a meeting place for hackers from across the globe.

DEF CON 26 will host several leading talks on security, and we’re thrilled that our CTO, Pedro Fortuna, will be doing a talk on protecting crypto exchanges.

The Talk

If we take a look back at the last 12 months, we can spot a massive increase in the value of cryptocurrencies. This, coupled with the emergence of hundreds of new coins and ICOs, got millions of people into a true investment frenzy.

A significant portion of entrants in cryptocurrency trading were non-technical consumers who were hyped into creating accounts on the most popular crypto exchanges like Coinbase or Bitstamp. This resulted in exchanges experiencing meteoric growth like never before.

Known malware families, including Zeus Panda, Ramnit, and Trickbot are already aiming at websites such as or This leads us to this talk: Protecting Crypto Exchanges From a New Wave of Man-in-the-Browser Attacks.

Pedro Fortuna will detail how these attacks work, from account takeover to sending the coins out to attacker-controlled wallets. He will also discuss current defenses (e.g. multi-factor authentication or strong SSL encryption) and why they are failing to mitigate this type of attack.

The talk will take place Friday, August 10th at 2 p.m. in the Packet Hacking Village.
