Zg\u0142oszono<\/a><\/noindex> o fali atak skierowanych na szyfrowanie repozytori\u00f3w Gita w serwisach GitHub, GitLab i Bitbucket. Atakuj\u0105cy usuwaj\u0105 repozytorium i zostawiaj\u0105 wiadomo\u015b\u0107 z pro\u015bb\u0105 o przes\u0142anie 0,1 BTC (oko\u0142o 700 USD) w celu przywr\u00f3cenia danych z kopii zapasowej (w rzeczywisto\u015bci uszkadzaj\u0105 jedynie nag\u0142\u00f3wki commit\u00f3w, a informacje mog\u0105 by\u0107 przywr\u00f3cono<\/a><\/noindex>). Na GitHubie w ten spos\u00f3b ju\u017c cierpia\u0142<\/a><\/noindex> 371 repozytori\u00f3w.<\/p>\n

Niekt\u00f3rzy ofiary ataku przyznaj\u0105, \u017ce u\u017cywali niesolidnych hase\u0142 lub zapomnieli usun\u0105\u0107 tokeny dost\u0119pu z starych aplikacji. Niekt\u00f3rzy s\u0105dz\u0105 (to wci\u0105\u017c tylko spekulacje i hipoteza nie zosta\u0142a jeszcze potwierdzona), \u017ce przyczyn\u0105 wycieku danych uwierzytelniaj\u0105cych by\u0142a kompromitacja aplikacji SourceTree<\/a><\/noindex>, zapewniaj\u0105cej GUI do pracy z Gitem na macOS i Windows. W marcu w SourceTree zidentyfikowano kilka krytycznych luk bezpiecze\u0144stwa<\/a><\/noindex>, kt\u00f3re umo\u017cliwiaj\u0105 zdalne wykonanie kodu przy dost\u0119pie do repozytori\u00f3w kontrolowanych przez przest\u0119pc\u00f3w.<\/p>\n

Aby przywr\u00f3ci\u0107 repozytorium po ataku, wystarczy wykona\u0107 \u201egit checkout origin\/master\u201d, po czym
\ndowiedzie\u0107 si\u0119 za pomoc\u0105 \u201egit reflog\u201d hasza SHA swojego ostatniego commita i zresetowa\u0107 zmiany atakuj\u0105cych poleceniem \u201egit reset {SHA}\u201d. W przypadku posiadania lokalnej kopii problem rozwi\u0105zuje si\u0119 poprzez wykonanie \u201egit push origin HEAD:master --force\u201d.<\/p>\n
