Ponovno pozdrav! Opet sam prona\u0161ao otvorenu bazu s medicinskim podacima za vas. Podsje\u010dam vas da su nedavno bile tri moje \u010dlanke o ovoj temi: curenje osobnih podataka pacijenata i lije\u010dnika iz medicinske online usluge DOC+<\/a><\/noindex>, ranjivost usluge \u201eDoktor tu\u201d<\/a><\/noindex> i curenje podataka hitnih medicinskih stanica<\/a><\/noindex>.<\/p>\n

<\/p>\n

Ovaj put je u otvorenom pristupu bio server Elasticsearch s logovima medicinskog IT sustava mre\u017ee laboratorija \u201eCentar molekularne dijagnostike<\/em>\u201c (CMD, www.cmd-online.ru).<\/p>\n

<\/a><\/noindex><\/p>\n

Odri\u010demo se odgovornosti: sve informacije u nastavku objavljuju se isklju\u010divo u obrazovne svrhe. Autor nije imao pristup osobnim podacima tre\u0107ih strana i kompanija. Informacije su preuzete ili iz otvorenih izvora ili su ih autoru dostavili anonimni \u0434\u043e\u0431\u0440\u043e\u0436\u0435\u043b\u0430\u0442\u0435\u043b\u0438.<\/code><\/p>\n

<\/p>\n

Server je otkriven ujutro 1. travnja i nije mi se \u010dinilo nimalo smije\u0161nim. Obavijest o problemu poslana je u CMD oko 10 sati ujutro (MSK) i oko 15:00 baza je postala nedostupna. <\/p>\n

<\/p>\n

Prema podacima pretra\u017eiva\u010da Shodan, ovaj server prvi put je postao dostupan javnosti 09.03.2019. O tome, kako se otkrivaju otvorene baze podataka Elasticsearch<\/a><\/noindex>, pisao sam poseban \u010dlanak.<\/p>\n

<\/p>\n

Iz logova se mogla dobiti prili\u010dno osjetljiva informacija, uklju\u010duju\u0107i ime i prezime, spol, datume ro\u0111enja pacijenata, ime i prezime lije\u010dnika, cijenu istra\u017eivanja, podatke istra\u017eivanja, datoteke s rezultatima screening-a<\/strong> i jo\u0161 mnogo toga.<\/p>\n

<\/p>\n

Primjer loga s rezultatima analiza pacijenta:<\/p>\n

Sve osjetljive podatke zamijenio sam simbolom \u201eX\u201c. U stvarnosti su svi bili pohranjeni u otvorenom obliku.<\/em><\/p>\n
<\/p>\n
Iz takvih logova lako (dekodiranjem iz Base64) je moglo biti mogu\u0107e dobiti PNG datoteke s rezultatima screening-a, ve\u0107 u prikladnom formatu za \u010ditanje:<\/p>\n

<\/p>\n
Ukupna veli\u010dina logova prema\u0161ila je 400 MB i ukupno je sadr\u017eavala vi\u0161e od milijun zapisa. Jasno je da svaki zapis nije predstavljao podatke jedinstvenog pacijenta.<\/p>\n
<\/p>\n
Slu\u017ebeni odgovor CMD-a: <\/p>\n
<\/p>\n
\u017delimo vam zahvaliti na brzo dostavljenim informacijama 01.04.2019. o ranjivosti u bazi podataka za logiranje i pohranu gre\u0161aka Elasticsearch. <\/p>\n
Na temelju tih informacija, na\u0161i zaposlenici u suradnji s relevantnim stru\u010dnjacima ograni\u010dili su pristup nazna\u010denoj bazi. Gre\u0161ka u prijenosu povjerljivih informacija u tehni\u010dku bazu je ispravljena.<\/p>\n
Prilikom razmatranja incidenta utvr\u0111eno je da se pojava nazna\u010dene baze s gre\u0161kom javila zbog ljudskog faktora. Pristup podacima brzo je zatvoren 01.04.2019. <\/p>\n
Trenutno se provode aktivnosti od strane internih i anga\u017eiranih vanjskih stru\u010dnjaka za dodatnu reviziju IT infrastrukture u vezi s za\u0161titom podataka. <\/p>\n
Na\u0161a organizacija je razvila poseban pravilnik o postupanju s osobnim podacima i sustavom razine odgovornosti osoblja. <\/p>\n
Trenutna softverska infrastruktura predvi\u0111a kori\u0161tenje baze Elasticsearch za pohranu gre\u0161aka. Kako bi se pove\u0107ala pouzdanost rada nekih sustava, provest \u0107e se migracija odgovaraju\u0107ih servera u podatkovni centar na\u0161eg partnera, u certifikirano softversko-hardware okru\u017eenje. <\/p>\n
