Look,cerita lucah kakak kandung we get it: cybersecurity is hard.

Still, you'd think the folks at the Black Hat cybersecurity conference in Las Vegas this week would have a better handle on things. And yet, according to noted French security researcher Baptiste Robert, they still managed to release a conference app that could put attendees' phones at risk.

The conference, which is now in its 22nd year, runs Aug. 3-8, and is ground zero for cybersecurity companies peddling their wares. It's followed by the DEF CON hacking conference, also in Las Vegas, which has a decidedly non-corporate ethos.

"The official Android app of #BHUSA is a joke," wrote Robert, who is in town for both Black Hat and DEF CON. "For an event of this size this is not serious @BlackHatEvents."

Robert, who goes by the handle Elliot Alderson on Twitter, laid bare what he says are the Android app's flaws in no uncertain terms.

"Thanks to the #BlackHat app, an attacker can: - Open a random url in the app browser - Pre dial a number - Create an email - Open Chrome to download a file."

Now, importantly, Robert added that the Black Hat app alone is not enough for a theoretical attacker to ruin someone's day. Rather, it would be a part of a one-two punch involving tricking a victim into downloading another app of the attacker's making.

And, before everyone at Black Hat abandons their phones in the desert, Robert assured those concerned that it's "not a high priority."

Even so, he wrote, "it's still a shame to have something like this in the app of the biggest security conference of the world."

And perhaps that's the real takeaway: Even the pros can make mistakes.

We contacted Robert to ask just how easy this type of attack would be to pull off in the wild, and will update if we hear back.

That an app associated with a security conference has its own security issues isn't exactly reassuring. It also isn't the first time it's happened. In 2018, the RSA security conference app exposed attendees' personal data, forcing organizers to scramble to resolve the issue.

We reached out to Black Hat in an attempt to determine just what, if anything, it plans to do to resolve the issues highlighted by Robert. While we have not heard back as of press time, we assume the organizers of "the world's leading information security event" are totally on top of things.
