Stručnjak za sigurnost najavljuje što mogu očekivati u idućim danima i na što treba obratiti pozornost [alias] => trebaju-li-korisnici-a1-strahovati-od-posljedica-ovog-hakerskog-strucnjak-za-sigurnost-najavljuje-sto-mogu-ocekivati-u-iducim-danima-i-na-sto-treba-obratiti-pozornost [catid] => 142 [published] => 1 [introtext] => [fulltext] =>

Nakon hakerskog napada na A1, moguće posljedice komentirao je za N1 stručnjak za sigurnost Markom Rakarom koji je, među ostalim, govorio o tome kako se zaštititi na internetu.

“Lozinka prvenstveno mora biti jako dugačka. 12 ili 14 znakova. Passwordi koji su 14 znakova ili više se smatraju sigurnima danas i jako ih je teško probiti, matematički broj permutacija potreban da bi se provalio je toliki da ga je jako teško probiti”, rekao je Rakar.

Komentirajući individualnu sigurnost korisnika na internetu, Rakar je rekao da su, ako se promatra povijest svih hakerskih napada dosad, uglavnom hakirani razni sustavi.

“Moć individualnog korisnika da spriječi takvu krađu je iznimno mala. Ono što se dogodilo ovaj tjedan A1 dogodilo se i drugima. Neusporedivo veće i moćnije kompanije bile su na udaru hakera. Svaka kompanija koju možete zamisliti je svakodnevno pod raznim napadima, a nekad ti napadi urode plodom za onog koji napada”, rekao je Rakar. Haker, dodao je, ne mora biti osobito talentiran.

“Iznimno je teško braniti kompleksne sustave. U konkretnom slučaju, proboj se po svoj prilici dogodio na način da je haker iskoristio pristup u neku od aplikacija koju A1 koristi za upravljanje svojim korisnicima. Sigurnost u toj aplikaciji očigledno nije bila adekvatna. Kako je on došao da uđe u tu aplikaciju ne možemo znati, ali tehnički gledano mogao se u nekom centru A1 nagnuti i pogledati link u pregledniku djelatnika i to iskoristiti”, rekao je Rakar. Komentirao je i koje su posljedice koje mogu trpjeti korisnici čiji su podaci iscurili.

“Ti će ljudi početi dobivati spam mailove raznih dućana koji će im slati svoju propagandnu poruku. To je najbenigniji korak. Sljedeći korak je, budući da imamo imena i prezimena, mail adrese i ujedno i korisnička imena, koja se mogu koristiti da bi se netko prijavio u vaš mail”, rekao je Rakar, dodavši da postoje programi koji pretražuju baze dosad korištenih lozinki.

“Vi danas za 3 minute možete downloadati dokument s interneta gdje se nalaze dvije tri milijarde passworda koje su probijene. Treba samo otkriti koji password je korišten od kojeg korisnika”, rekao je Rakar za N1.

Nakon hakerskog napada na A1, moguće posljedice komentirao je za N1 stručnjak za sigurnost Markom Rakarom koji je, među ostalim, govorio o tome kako se zaštititi na internetu.

“Lozinka prvenstveno mora biti jako dugačka. 12 ili 14 znakova. Passwordi koji su 14 znakova ili više se smatraju sigurnima danas i jako ih je teško probiti, matematički broj permutacija potreban da bi se provalio je toliki da ga je jako teško probiti”, rekao je Rakar.

Komentirajući individualnu sigurnost korisnika na internetu, Rakar je rekao da su, ako se promatra povijest svih hakerskih napada dosad, uglavnom hakirani razni sustavi.

“Moć individualnog korisnika da spriječi takvu krađu je iznimno mala. Ono što se dogodilo ovaj tjedan A1 dogodilo se i drugima. Neusporedivo veće i moćnije kompanije bile su na udaru hakera. Svaka kompanija koju možete zamisliti je svakodnevno pod raznim napadima, a nekad ti napadi urode plodom za onog koji napada”, rekao je Rakar. Haker, dodao je, ne mora biti osobito talentiran.

“Iznimno je teško braniti kompleksne sustave. U konkretnom slučaju, proboj se po svoj prilici dogodio na način da je haker iskoristio pristup u neku od aplikacija koju A1 koristi za upravljanje svojim korisnicima. Sigurnost u toj aplikaciji očigledno nije bila adekvatna. Kako je on došao da uđe u tu aplikaciju ne možemo znati, ali tehnički gledano mogao se u nekom centru A1 nagnuti i pogledati link u pregledniku djelatnika i to iskoristiti”, rekao je Rakar. Komentirao je i koje su posljedice koje mogu trpjeti korisnici čiji su podaci iscurili.

“Ti će ljudi početi dobivati spam mailove raznih dućana koji će im slati svoju propagandnu poruku. To je najbenigniji korak. Sljedeći korak je, budući da imamo imena i prezimena, mail adrese i ujedno i korisnička imena, koja se mogu koristiti da bi se netko prijavio u vaš mail”, rekao je Rakar, dodavši da postoje programi koji pretražuju baze dosad korištenih lozinki.

“Vi danas za 3 minute možete downloadati dokument s interneta gdje se nalaze dvije tri milijarde passworda koje su probijene. Treba samo otkriti koji password je korišten od kojeg korisnika”, rekao je Rakar za N1.
