- [ ] Was ist Credential Stuffing | ||

} | ||
|
||
Was wird geklaut { | ||
- [ ] Username/E-Mail Adresse+Hash war gestern! | ||
- [ ] Username/E-Mail Adresse+Klartextpasswort ist heute! | ||
- [ ] manchmal auch mehr (Bsp: Ashley Madison) | ||
} | ||
|
||
Beispiel { | ||
- [ ] 1.4 bln beispiel - Bash | ||
- [ ] Collections 1-5 grep | ||
- [ ] Datenqualität, wie alt ist das zeug, repackaging… | ||
} | ||
|
||
Wie schützen? { | ||
- [ ] have i been pwned | ||
- [ ] 2FA | ||
- [ ] sms no no no! | ||
- [ ] OTP App - Wo liegt die restgefahr - Beispiel Authy + Applewatch | ||
- [ ] PW Manager und 2FA App in einem? Oder doch lieber 2 getrennte? | ||
- [ ] Einzelapps (Bsp: Google, Microsoft Authenticator, Wordpress, Gemalto, uvm….) - Online Bestätigung sicherer als OTP Eingabe | ||
- [ ] Best: yubikey: u2f (oder andere) | ||
- [ ] Firmen: Professionelle Dienste wie Recorded Futures | ||
- [ ] Firmen: Daten besorgen und auswerten | ||
} | ||
|
||
Addon: Umgang mit großen Datenmengen (wenn genügend Zeit) { | ||
- [ ] Datenbanken bauen? Schönes Hobbyprojekt - Wer Zeit dafür hat... -> Indexgröße? | ||
- [ ] Schnelle CPU mit vielen Kernen | ||
- [ ] 10gbit vs 40gbit usbc/thunderbolt3 hdd cases + Samsung Evo -> Achtung Strom | ||
- [ ] egrep vs. fgrep | ||
- [ ] egrep langsamer mit jedem einezlnen oder verknüpften Suchstring! | ||
- [ ] LC_ALL=C | ||
- [ ] Cuda grep? Bisher nicht vernünftig zum laufen bekommen! | ||
