Zidentyfikowano kompromitacj\u0119 oficjalnego dodatku Claude Code do VS Code, dostarczanego przez firm\u0119 Anthropic, kt\u00f3ry ma 63 miliony pobra\u0144. Atakuj\u0105cemu uda\u0142o si\u0119 umie\u015bci\u0107 w katalogu Open-VSX wersj\u0119 anthropic.claude-code@2.1.313, zawieraj\u0105c\u0105 z\u0142o\u015bliwy kod do zdalnego dost\u0119pu do systemu u\u017cytkownika. Publikacja z\u0142o\u015bliwej wersji pakietu w repozytorium Microsoftu nie zosta\u0142a potwierdzona, ale stworzono r\u00f3wnie\u017c raport z ostrze\u017ceniem dla niej. Obecnie problematyczna wersja zosta\u0142a usuni\u0119ta z repozytorium Open-VSX, a nast\u0119pnie opublikowano poprawion\u0105 wersj\u0119 2.1.314.<\/p>\n

Kod do za\u0142adowania z\u0142o\u015bliwych komponent\u00f3w zosta\u0142 dodany na pocz\u0105tku pliku extension.js i zosta\u0142 aktywowany przy inicjalizacji dodatku po uruchomieniu VS Code (do aktywacji z\u0142o\u015bliwego kodu nie by\u0142o wymagane interakcja u\u017cytkownika z Claude). Z\u0142o\u015bliwa aktywno\u015b\u0107 ogranicza\u0142a si\u0119 do utworzenia katalogu ~\/.ssh i dodania do pliku ~\/.ssh\/authorized_keys otwartego klucza ssh-ed25519 z adnotacj\u0105 \u201esvc-telemetry\u201d. Nast\u0119pnie przeprowadzano sprawdzenie obecno\u015bci procesu sshd w systemach Linux i macOS oraz aktywacj\u0119 serwera SSH w przypadku jego braku. W systemie Windows za pomoc\u0105 PowerShell instalowano OpenSSH. <\/p>\n

Nast\u0119pnie z\u0142o\u015bliwy kod zapisywa\u0142 prywatny klucz do tymczasowego pliku o nazwie \u201e.stk_*\u201d i konfigurowa\u0142 odwr\u00f3cony tunel z zewn\u0119trznym serwerem SSH 134.209.82.225 w celu zdalnego dost\u0119pu, uruchamiaj\u0105c ssh z opcjami \u201e-N -R \u2018*:0:localhost:22\u2019\u201d. Po\u0142\u0105czenie by\u0142o od\u015bwie\u017cane co 60 sekund. Skrypty do aktualizacji tunelu i przesy\u0142ania danych do zewn\u0119trznych. serwery<\/a> by\u0142y przechowywane w plikach ~\/.config\/.smt oraz ~\/.config\/.smtk. Okresowe uruchamianie w systemie Linux by\u0142o konfigurowane przez cron, w macOS przez LaunchAgent (com.apple.sysmond.plist), a w Windows przez SysMon i autostart.<\/p>\n

Dodatkowo w systemie zbierano informacje na temat nazwy hosta, zarejestrowanych u\u017cytkownik\u00f3w, systemu operacyjnego, katalogu domowego, email (przez git config \u2014global user.email) oraz zmiennych \u015brodowiskowych z nazwami zawieraj\u0105cymi s\u0142owa KEY, TOKEN, SECRET, PASS, AWS i GCP. Zebrane dane wysy\u0142ano w formacie JSON pod adres URL http:\/\/134.209.82.225:8099\/beacon.<\/p>\n

U\u017cytkownikom dodatku Claude Code do VS Code zaleca si\u0119 sprawdzenie swoich system\u00f3w pod k\u0105tem instalacji z\u0142o\u015bliwej wersji 2.1.313. Wska\u017anikami kompromitacji systemu s\u0105 pojawienie si\u0119 plik\u00f3w ~\/.config\/.smt, ~\/.config\/.smtk, ~\/.Library\/LaunchAgents\/com.apple.sysmond.plist, ${TMPDIR}\/.stk_*, ~\/.config\/smt.cmd,
\n~\/.config\/smtk, SysMon i sysmon.cmd, a tak\u017ce po\u0142\u0105czenia na portach 22 i 8099. adresem IP<\/a> 134.209.82.225 oraz wysy\u0142anie \u017c\u0105da\u0144 HTTP\/HTTPS do host\u00f3w ifconfig.me i api.ipify.org.<\/p>\n

Nie jest jeszcze jasne, jak dok\u0142adnie przest\u0119pcy uzyskali mo\u017cliwo\u015b\u0107 wstrzykni\u0119cia z\u0142o\u015bliwego kodu do dodatku. Zak\u0142ada si\u0119, \u017ce mog\u0142a zosta\u0107 zhakowana konto pracownika Anthropic odpowiedzialnego za wsparcie pakietu lub wykorzystano luk\u0119 w systemie publikacji wyda\u0144.
