Jednom prilikom je bio phishing sa mup.gov.rs adrese i nekim cudom sam posmatrao gov.rs kao tld a ne domen (nisam nikada proveravao).
Kad ono medjutim, gov.rs je domen registrovan 10.3.2008 i po history-u nikada nije imao DMARC record DNS zapisu cime je moguce spoofovati SVE adrese sa liste:
Alarmantno!

mozete i sami proveriti: https://www.smartfense.com/en-us/tools/spoofcheck/

Ukoliko tragate za besplatnim alatima otvorenog koda za security, postoji sajt https://securityonline.info/ na kome mozete pored vesti pronaci mnostvo korisnih alata.
To je odlicna pocetna tacka ako ste novi u security-ju i ne znate jos sta sve postoji i cime bi ste se konkretno bavili, pa mozete lako isprobati neke alate i odluciti sta vam je korisno i sta vam se svidja.
Ja koristim ovaj sajt da sa vremena na vreme vidim koji novi alati i za koje napade/odbrane/analize su izasli i ako me opis 'kupi' probam i onda uvrstim u svoj arsenal.
Nadam se da ce i drugima ovaj sajt pomoci ako sto je i meni. Smile

Svako ima neke svoje sajtove koje prati za vesti u vezi najnovijih sajber vesti.

Bio vam to posao ili ne korisno je cesto informisati se o najnovijim vrstama napada, otkrivenim propustima i hakovanim firmama kako bi znali da li ste i vi ugrozeni, vasi podaci (na vasim uredjajima ili u posedstvu servisa koji koristite) ili softver i hardver koji koristite.

Evo liste sajtova koje ja pratim i sa kojih se informisem za najnovije vesti ali i detaljnije analize virusa i propusta kao i hakerskih taktika.

Izvor: https://qutech.nl/2022/10/03/untappable-...echnology/. Termin za istraživanje tehnologije: "The superconducting nanowire single-photon detector (SNSPD or SSPD)".

Glavna razlika u odnosu na dosadašnje sisteme PKI i monitoring je:

Quote:A solution to eavesdropping—now and in the future—is the use of quantum key distribution (QKD). In quantum communication, eavesdropping on a message disturbs transmission of the quantum key. Slater: “If the quantum signals are disturbed, the users know not to use the generated key for their secure communication line. Once the quantum key is successfully shared with the intended recipient, the rest of the secure communication benefits from ‘forward secrecy’: the assurance that the key distribution cannot be cracked now or in the future.”
