Un grup de cercet\u0103tori de la Universitatea Politehnic\u0103 din Virginia, precum \u0219i companiile Cyentia \u0219i RAND, a publicat<\/a><\/noindex> rezultatele analizei riscurilor asociate cu aplicarea diferitelor strategii de corectare a vulnerabilit\u0103\u021bilor. Studiind 76.000 de vulnerabilit\u0103\u021bi identificate \u00eentre 2009 \u0219i 2018, s-a constatat c\u0103 doar 4.183 dintre acestea (5.5%) au fost folosite \u00een atacuri reale. Rata ob\u021binut\u0103 este de cinci ori mai mare dec\u00e2t prognozele publicate anterior, care estimau num\u0103rul problemelor exploatate la aproximativ 1.4%.<\/p>\n

\u00cen acela\u0219i timp, nu a fost g\u0103sit\u0103 nicio corela\u021bie \u00eentre publicarea prototipurilor de exploit \u00een acces liber \u0219i \u00eencerc\u0103rile de a exploata vulnerabilit\u0103\u021bile. Din toate cazurile de exploatare a vulnerabilit\u0103\u021bilor cunoscute de cercet\u0103tori, doar \u00een jum\u0103tate dintre situa\u021bii prototipul exploit-ului a fost anterior publicat \u00een surse deschise. Absen\u021ba unui prototip de exploit nu \u00eei opre\u0219te pe atacatori, care, dac\u0103 este cazul, \u00ee\u0219i creeaz\u0103 singuri exploiturile.<\/p>\n

Din alte concluzii, se observ\u0103 c\u0103 vulnerabilit\u0103\u021bile cu un nivel ridicat de severitate conform clasific\u0103rii CVSS sunt cele mai c\u0103utate pentru exploatare. Aproape jum\u0103tate dintre atacuri au folosit vulnerabilit\u0103\u021bi cu un punctaj de cel pu\u021bin 9. <\/p>\n

Num\u0103rul total de prototipuri de exploits publicate \u00een perioada analizat\u0103 a fost estimat la 9.726. Datele utilizate \u00een studiu privind exploiturile au fost ob\u021binute din
\ncolec\u021biile Exploit DB, Metasploit, Elliot Kit D2 Security, Canvas Exploitation Framework, Contagio, Reversing Labs \u0219i Secureworks CTU.
\nInforma\u021biile despre vulnerabilit\u0103\u021bi au fost ob\u021binute din baza de date NIST NVD<\/a><\/noindex> (National Vulnerability Database). Informa\u021biile despre incidentele de exploatare au fost consolidate pe baza datelor de la FortiGuard Labs, SANS Internet Storm Center, Secureworks CTU, OSSIM de la Alienvault \u0219i ReversingLabs.<\/p>\n

Studiul a fost realizat pentru a determina echilibrul optim \u00eentre aplicarea actualiz\u0103rilor \u00een cazul identific\u0103rii unor vulnerabilit\u0103\u021bi \u0219i remedieri doar pentru cele mai periculoase probleme. \u00cen primul caz, se asigur\u0103 o eficien\u021b\u0103 ridicat\u0103 a protec\u021biei, dar sunt necesare resurse mari pentru \u00eentre\u021binerea infrastructurii, care sunt cheltuite \u00een principal pentru corectarea problemelor minore. \u00cen al doilea caz, exist\u0103 un risc mare de a pierde o vulnerabilitate care poate fi folosit\u0103 pentru a lansa un atac. Studiul a ar\u0103tat c\u0103, atunci c\u00e2nd se iau decizii cu privire la instalarea unei actualiz\u0103ri pentru remedierea unei vulnerabilit\u0103\u021bi, nu ar trebui s\u0103 ne baz\u0103m pe absen\u021ba unui prototip de exploit publicat, iar \u0219ansa de exploatare depinde direct de nivelul de pericol al vulnerabilit\u0103\u021bii.<\/p>\n
