Bun\u0103 din nou! Am g\u0103sit din nou pentru voi o baz\u0103 de date deschis\u0103 cu informa\u021bii medicale. \u00cemi amintesc c\u0103 recent au fost publi\u00e9e trei articole ale mele pe aceast\u0103 tem\u0103: scurgerea de date personale ale pacien\u021bilor \u0219i medicilor din serviciul medical online DOC+<\/a><\/noindex>, vulnerabilitatea serviciului \u201eDoctor l\u00e2ng\u0103 mine\u201d<\/a><\/noindex> \u0219i scurgerea datelor sta\u021biilor de ambulan\u021b\u0103<\/a><\/noindex>.<\/p>\n

De data aceasta, a fost f\u0103cut\u0103 public\u0103 un server Elasticsearch cu jurnalele sistemului IT medical al re\u021belei de laboratoare \u201eCentrul de diagnostic molecular<\/em>\u201c (CMD, www.cmd-online.ro).<\/p>\n

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

Declinare de responsabilitate: toate informa\u021biile de mai jos sunt publicate exclusiv \u00een scopuri educa\u021bionale. Autorul nu a avut acces la datele personale ale ter\u021bilor sau ale companiilor. Informa\u021biile sunt preluate fie din surse publice, fie au fost furnizate autorului de c\u0103tre anonimi binevoitori.<\/code><\/p>\n

<\/p>\n

Serverul a fost descoperit diminea\u021ba zilei de 1 aprilie \u0219i nu mi s-a p\u0103rut deloc amuzant. Notificarea despre problem\u0103 a fost trimis\u0103 la CMD \u00een jurul orei 10:00 (ora Moscovei) \u0219i \u00een jurul orei 15:00 baza de date a devenit inaccesibil\u0103. <\/p>\n

<\/p>\n

Potrivit motorului de c\u0103utare Shodan, acest server a fost f\u0103cut public pentru prima dat\u0103 pe 09.03.2019. Despre cum se descoper\u0103 bazele de date deschise Elasticsearch , am scris un articol separat.<\/a><\/noindex>Din jurnale se putea ob\u021bine informa\u021bii foarte sensibile, inclusiv<\/p>\n

<\/p>\n

Nume \u0219i prenume, sex, date de na\u0219tere ale pacien\u021bilor, nume \u0219i prenume ale medicilor, costul cercet\u0103rilor, datele cercet\u0103rilor, fi\u0219iere cu rezultatele screening-ului Un exemplu de jurnal cu rezultatele analizelor unui pacient:<\/strong> \u0219i multe altele.<\/p>\n

<\/p>\n

Exemplu de jurnal cu rezultatele analizelor pacientului:<\/p>\n

<\/p>\n

\"Pa\u0219aport0423BF97FA5E-1DWW98675708386841791018.03.2019\u0420\u041e\u0421\u0421 RU.13\u0421\u041a03.006012iVBORw0KGgoAAAANSUhEUgAABfoAAAfuCAIAAAArOR8rAAD\/\/0lEQVR4Xuy9P7BtQ7u+\/e3oECF6iRAhQoQI0SZCtIkQIdpEiBCxI0SIECFiV50qRKg6VYgQIUKEiDfiRL7rnPtXz+nqHnPMsfb6s+cc61rBqjl79Oh++uoe\/eceT\/c8888\/\/\/\/<\/code><\/pre>\n

Am \u00eenlocuit toate datele sensibile cu simbolul \u201eX\u201d. \u00cen realitate, totul a fost stocat \u00een mod deschis.<\/em><\/p>\n
<\/p>\n
Din astfel de jurnale, prin decodare din Base64, se puteau ob\u021bine fi\u0219iere PNG cu rezultatele screening-ului, deja \u00eentr-o form\u0103 u\u0219or de citit:<\/p>\n

<\/p>\n
Dimensiunea total\u0103 a jurnalelor a dep\u0103\u0219it 400 MB \u0219i con\u021binea \u00een total mai mult de un milion de \u00eenregistr\u0103ri. Este clar c\u0103 nu fiecare \u00eenregistrare reprezenta date ale unui pacient unic.<\/p>\n
<\/p>\n
R\u0103spuns oficial din partea CMD: <\/p>\n
<\/p>\n
Dorim s\u0103 v\u0103 mul\u021bumim pentru informa\u021biile transmise rapid pe 01.04.2019 despre vulnerabilitatea din baza de date de \u00eenregistrare \u0219i stocare a erorilor Elasticsearch. <\/p>\n
Pe baza acestei informa\u021bii, angaja\u021bii no\u0219tri, \u00eempreun\u0103 cu speciali\u0219tii relevan\u021bi, au restric\u021bionat accesul la baza de date men\u021bionat\u0103. Problema transmiterii informa\u021biilor confiden\u021biale \u00een baza tehnic\u0103 a fost rezolvat\u0103.<\/p>\n
\u00cen cursul investig\u0103rii incidentului, s-a constatat c\u0103 apari\u021bia \u00een spa\u021biul public a acestei baze cu jurnalul erorilor a avut loc din cauza factorului uman. Accesul la date a fost \u00eenchis rapid pe 01.04.2019. <\/p>\n
\u00cen prezent, speciali\u0219ti interni \u0219i externa\u021bi desf\u0103\u0219oar\u0103 activit\u0103\u021bi pentru un audit suplimentar al infrastructurii IT \u00een scopul protec\u021biei datelor. <\/p>\n
Organiza\u021bia noastr\u0103 a dezvoltat un regulament special pentru gestionarea datelor personale \u0219i a sistemului de responsabilitate pe niveluri pentru personal. <\/p>\n
Infrastructura software actual\u0103 preconizeaz\u0103 utilizarea bazei Elasticsearch pentru stocarea erorilor. Pentru a \u00eembun\u0103t\u0103\u021bi fiabilitatea oper\u0103rii unor sisteme, va fi realizat\u0103 migrarea serverelor corespunz\u0103toare \u00een data center-ul partenerului nostru, \u00eentr-un mediu software \u0219i hardware certificat. <\/p>\n
