North Korean infiltrator caught working in Amazon IT department thanks to lag — 110ms keystroke input raises red flags over true location

North Korean infiltrator caught working in Amazon IT department thanks to lag — 110ms keystroke input raises red flags over true location

Amazon security experts took a closer look at the flagged ‘U.S. remote worker’ and determined that their remote laptop was being remotely controlled – causing the extra keystroke input lag. Schmidt emphasizes that good-quality security software was key to this investigation.

It turns out that the DPRK had access to this Amazon laptop located in Arizona. A woman found to be facilitating this fraud on behalf of North Korean imposter workers was sentenced to several years in prison earlier this year.

As well as red flag computer network symptoms, the fumbling use of American idioms and English-language articles continues to be a giveaway when conversing with such impostors.

The problem of North Koreans infiltrating U.S. corporations for profit, mischief, and more is undoubtedly a serious one. We’ve covered sizable FBI seizures of equipment recently, perhaps showing just the tip of the iceberg. More successful infiltrations by the DPRK, as well as hostile nations like Iran, Russia, and China, are likely to be ongoing.

llehcida I'd like to hire the NK IT department for where I work: he is jumping through at least two vpns, spoofing ip, maybe a tor system, and a trans-pacific cable. His latency is half what I have to deal with on a day to day basis and everything I connect to is in the same building or half a mile away. I'm literally jealous of his NK technology. And yes, I made an account for the first time because I'm waiting on my systems and I'm impressed with his. Reply

gggplaya Unfortunately, this will just be a lesson for them on how to thwart Amazon again. Amazon should have never released information on how they were caught. Now, they'll still remote into the laptop, but then also use something like a raspberry pi has an HID (keyboard and mouse) and remote into the raspberry pi attached to the laptop. Reply

In all likelihood, it probably was no longer a secret. And also tbf, it required Amazon work laptops, and the woman who was selling them out to NKs was arrested years ago, so the NKs probably caught on at that point. Reply

What you might be referring to is, at best, their ingenuity and persistence in utilizing them. Reply

JamesJones44 I wonder if NK paid to fly him over for the interview and got a Visa? It's rare Amazon does IT interviews remote, but I suppose it's possible. Reply

I have no idea how the situation here developed, but from what I understand for this kind of thing for similar situations, what will sometimes happen is Person A shows up as the candidate and goes and does all the interviewing, but is actually a proxy for Person B, who is the one who ends up actually doing the job after Person A gets "hired". I've heard stories where a company has interviewed and hired someone, then on the start date a completely different person shows up for the job pretending to be the original person. In some large companies with multiple layers of bureaucracy and management, it can be quite some time before the switcheroo even gets noticed, if it gets noticed at all. Reply

Or Person A, after having the job for a while, outsources his functions. Passes it off as his work, but it isn't. Reply

Snowrosered Hard to understand why anyone would work for them. They are a scourge. Talking about NKR Of course. Reply
