Are there more people in the penetration testing business who are flooded with emails from AI agents wanting to negotiate scope and purchase a penetration test?
Over the past few weeks, we have received a lot of them - and I mean A LOT - each wilder than the last. Almost all of the emails are from Gmail addresses and none of them have ever been seen or read by a human.
Additionally, almost all of these projects are related to cryptography in some way, such as messengers, crypto wallets, post-quantum stuff, file vaults and attestation tools.
If you are also getting flooded with these, would you mind reaching out to share experiences and maybe discuss them with us?
Edit: resolved

Are there any statistics I could look into? Not looking for engineering advice or suggestions what to use.
I hope to get a better understanding of the engineering practices & workflows and security needs to ensure that our security work in web standards can actually land with the users.
Edit: Specifically, I am interested how people modify/insert HTML :)

Das diese offizielle Verschleierungstaktik nicht hilfreich ist, haben wohl alle gemerkt. Nachgeordnete Einrichtungen sind davon leider genau so betroffen, wie der Rest der BevΓΆlkerung.
Wie auch immer. Da es jetzt kurz vor Freitag um Eins ist, ist das jetzt gesperrt.
Save this for emergency.
