360安全卫士for Linux使用结果:F*CK

测试了一把,结果显示360基本对Linux社区规范和安全常识not give a f*ck。 首先,这个deb包就是胡乱打包,依赖关系就没弄好:

$ dpkg-deb -I 360safeforlinux-3.0.0.66-stripped.deb 
[...]
 Package: 360safeforlinux
 Version: 3.0.0.66
 Architecture: amd64
 Maintainer: qihu360 company
 Installed-Size: 23617
 Depends: libc6 (>= 2.14),libglib2.0-0 (>= 2.38),python2.7 (>= 2.7.6),openssl(>= 1.0),curl,libqt4-network(>= 4.8.5),libqt4-sql(>= 4.8.5)
 Section: gnome
 Priority: required
 Essential: yes
 Description: 360 safe for linux

但是还实际依赖了libpython2.7和libqtgui4两个库没有标明,要我手动修复。 这个打包还通过滥用Essential标记来制造卸载的麻烦。

root@debian-amd64:/home/user# apt-get remove 360safeforlinux
[...]
The following packages will be REMOVED:
  360safeforlinux

关于Essential打包政策,DebianUbuntu都只保留给最必要的包。 安装后dpkg配置时它的postinst脚本直接给加上了setuid。如此随意地使用setuid,还能自称是安全?

if [ "$1" = "configure" ];then
    chmod u+s /opt/360safeforlinux/s360SafeForLinux
[...]
fi

这个的意思就是,以普通用户权限运行这个东西,它会变成root:

user@debian-amd64:~$ id
uid=1000(user) gid=1000(user) groups=1000(user),24(cdrom),25(floppy),29(audio),30(dip),44(video),46(plugdev)
user@debian-amd64:~$ start360 &
[1] 4512
user@debian-amd64:~$ pstree -u
init─┬─dhclient
     ├─5*[getty]
     ├─login───bash(user)───startx───xinit─┬─Xorg(root)
     │                                     └─x-window-manage
[...]
     ├─urxvtd(user)
     └─urxvtd(user)─┬─bash───start360(root)─┬─{BackendTaskThre}
                    │                       ├─{BrowserHomePage}
                    │                       ├─{CpuMemUseState}
                    │                       ├─{FileWatcher}
                    │                       ├─{IsolateZone}
                    │                       ├─{LogCleanThread}
                    │                       ├─2*[{MyThread}]
                    │                       ├─{VdUpload}
                    │                       └─3*[{start360}]
                    └─bash───pstree

dpkg的prerm脚本还有奇怪的东西:

rc=`lsmod | grep "rk360" | xargs echo`
if [ -n "$rc" ];then
    rmmod rk360 2>/dev/null 1>&2
    rm -rf /etc/360safe/360safe.ko 2>/dev/null 1>&2
fi

rc=`lsmod | grep "immu" | xargs echo`
if [ -n "$rc" ];then
    rmmod immu 2>/dev/null 1>&2
    rm -rf /etc/360safe/immu.ko 2>/dev/null 1>&2
fi

360不仅不满足于root权限,还在用内核模块?不过这次使用中并未发现这两个内核模块。 start360启动,然后有两个运行时怪现状:

  1. 把pid保存到/etc/360safe/360safeforlinux.pid。会不会遵守FHS?
  2. 疯狂扫描系统文件,powertop显示闲置状态每秒30个唤醒,笔记本电池寿命已死。会不会用inotify?

它提供了一些功能。

  • 全盘扫描。所有文件都是按照标准设计的,哪个恶意哪个不恶意真不是360能说了算的。
  • 一键清理。可以使用这个命令替代:rm -r ~/.adobe ~/.cache ~/.local ~/.macromedia ~/.thumbnails /tmp/*。但是这些临时文件是有用的,也占不了多大空间。
  • 优化加速。就是把update-rc.d/chkconfig封装了一个图形界面。
  • 软件管家。360的私货app store。
  • 文件粉碎。Linux下有什么无法删除的“顽固”文件?还是重新发明了coreutils的/usr/bin/shred?来删除/proc试试?
  • 网盾。就是Firefox和Chrome的插件。
./etc/360safe/urlcheck
./etc/360safe/urlcheck/normalize.py
./etc/360safe/urlcheck/Firefox
./etc/360safe/urlcheck/Firefox/360webshield@qihoo.com.xpi
./etc/360safe/urlcheck/lcloud.ini
./etc/360safe/urlcheck/browserextensionsinstaller.py
./etc/360safe/urlcheck/Chrome
./etc/360safe/urlcheck/Chrome/360WebShield.crx
  • 还有二进制库的“云查杀”,QEX引擎,BitDefender引擎。不了解有什么用处。

360唯有一点用功了,就是列了一大堆非GPL的许可证:

license/zlib_license.txt
license/c-ares_license.txt
license/qt_license_lgpl.txt
license/unrar_license.txt
license/sqlite_license.txt
license/elftoolchain_license.txt
license/libcurl_license.txt
license/7-Zip_license.txt
license/boost_license.txt
license/openssl_licnese.txt
license/minizip_license.txt
license/jsoncpp_license.txt
license/protobuf_license.txt
license/Noto fonts_license.txt
license/qt_lgpl_exception.txt

这样人们就无权索要源代码。不过,一个安全产品不公开源代码,然后用setuid拿了root还要搞内核模块,谁知道你要干嘛?总之,360对Linux社区规范和安全常识基本not give a f*ck。
