Identity-related data breaches are more severe and costly than run-of-the-mill incidents, according to RSA. 40% of respondents reported an identity-related security breach. Of those, 66% reported it as a severe event that affected their organization. 4… Continue reading Identity-related data breaches cost more than average incidents
RSA and Swissbit announced that RSA will start introducing its next-generation hardware authenticators RSA iShield Key 2 series powered by Swissbit alongside RSA ID Plus for Government. Built to meet the highest security standards, the RSA iShield Key … Continue reading RSA and Swissbit join forces to secure government agencies
I have setup an AlmaLinux9 server with SSHD. I have also generated a priv+pub key on my workstation, and when I check the algorithm used by my key it shows:
ssh-keygen -l -f myprivatekey.pem

During a CTF, as www-data, I managed to exfiltrate an .rnd file used by phpseclib on a PHP app (I exfiltrated the entire app). Since SSHD is configured with PubkeyAuthentication yes and PasswordAuthentication no, my guess is that i… Continue reading exfiltred .rnd file exploitation
RSA announced new passwordless, phishing-resistant capabilities that meet stringent technical standards and can help public sector agencies, contractors, and systems integrators fulfill Executive Order 14028 and National Security Memo 8 to improve the … Continue reading RSA Authenticator App improves cybersecurity for federal agencies
when i check connection status with google services (gmail for instance) i see that connection is secure. Then I can check certificate details. Chrome shows that it uses 3 different certificates with different public keys.
Hierarchy:
GTS … Continue reading Why chrome shows several certificates for encryption?
Ah, generic unbranded IP cameras. Safe, secure? Probably not. [Alex] has been hacking around with one of his very own, and he’s recently busted the thing wide open. Determining that …read more Continue reading Hacking an IP Camera To Run Your Own Software
Cryptography ain’t easy. Seemingly small details like how many times a computationally intensive loop runs can give the game away. [Lord Feistel] gives us a demo of how this could …read more Continue reading Undo Arduino Encryption with an Oscilloscope
I’ve noted that SHA256 of CSRs for RSA keys, generated as
openssl req -new -config leaf.conf -key rsa.key rsa.csr
are always the same, given the same key and configuration. In the same time, every time I regenerate CSR for ECC (P-384) key,… Continue reading Are ECC CSR always different and if yes, why? [closed]
Does anyone know what kind of keys are being generated when you make a Fido2/Webauthn passkey? rsa2048, rsa4096, Ed25519, or something else? Just worried if its rsa2048 it might soon be crackable, at least by state actors.
