Expert spots vulnerability in Dutch national security, gets trolled with a souvenir t-shirt for his efforts

Shai Eistein, an information security expert on LinkedIn, got more (or perhaps less) than he bargained for when he notified the CERT (Dutch Cyber Security) of a potential loose end in national security.

As Eistein’s LinkedIn post explains, he noticed that one of the Netherlands’ ships was using a satellite router with a default password. After notifying CERT of this, they responded that the “vulnerability was mitigated” and then โ€” they asked for his address.

Why? Because they wanted to send him a T-shirt.

This isn’t a joke, they literally sent him a T-shirt. ๐Ÿ˜ณ

And what did it say? ๐Ÿ‘‡

Good one, Dutch government. Image: Shai Eistein/LinkedIn

Some people in the comments were sceptical of Shai’s image to which he responded with an image of the back of the shirt which very clearly showed the logo for the Dutch government.

An ultimate Dad-level joke. It seems the Rijksoverheid has a sense of humour after all. ๐Ÿ˜‰

Sarah originally arrived in the Netherlands due to an inability to make her own decisions โ€” she was simply told by her mother to choose the Netherlands for Erasmus. Life here has been challenging (have you heard the language) but brilliant for Sarah, and she loves to write about it. When Sarah is not acting as a safety threat to herself and others (cycling), you can find her sitting in a corner of Leiden with a coffee, trying to sound witty.


  1. Well, in Germany you might get in some serious trouble with the law. At least a police raid… Ok it is much higher value, but not that kind of what I prefer. This T-Shirt is suddenly awesome. ๐Ÿ˜‰

  2. In Germany, they would have arrested him and confiscated all his computers. This is why we don’t have many IT security experts in Germany. And the few ones that are still here, won’t disclose exploits etc. to the government, because they like to shoot the messenger. ๐Ÿคท๐Ÿผโ€โ™‚๏ธ

  3. This post misses out on the Monkey Island reference this shirt seems to be. If that is intentional by the dutch government this is even sweeter.

  4. I would’ve hanged the t-shirt outside my house upside down – distress kind of message and shot some live videoes thanking the gov agency for their amazing generosity and compassion during these dire times … You never know where would that play a string or two
