Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
ByteBuffer
Advanced tools
nodejs版本的ByteBuffer和C++通信的利器!
var ByteBuffer = require('./ByteBuffer');
/*************************基本操作****************************/
//压包操作
var sbuf = new ByteBuffer();
var buffer = sbuf.string('abc123你好')//变长字符串,前两个字节表示长度
.int32(-999).uint32(999).float(-0.5)
.int64(9999999).double(-0.000005).short(32767).ushort(65535)
.byte(255)
.vstring('abcd',5)//定长字符串,不足的字节补0x00
.byteArray([65,66,67,68,69],5)//字节数组,不足字节补0x00
.pack();//结尾调用打包方法
console.log(buffer);
//解包操作
var rbuf = new ByteBuffer(buffer);
//解包出来是一个数组
var arr = rbuf.string()//变长字符串,前两个字节表示长度
.int32().uint32().float()
.int64().double().short().ushort()
.byte()
.vstring(null,5)//定长字符串,不足的字节补0x00
.byteArray(null,5)//字节数组,不足字节补0x00
.unpack();//结尾调用解包方法
console.log(arr);
/*************************更多操作****************************/
//指定字符编码(默认:utf8):utf8/ascii/
var sbuf = new ByteBuffer().encoding('ascii');
//指定字节序(默认:BigEndian)
var sbuf = new ByteBuffer().littleEndian();
//指定数据在二进制的初始位置 默认是0
var sbuf = new ByteBuffer(buffer,2);
//插入数据到指定位置
var sbuf = new ByteBuffer();
sbuf.int32(9999,0);//把这个int32数据插入到ByteBuffer的第一个位置
//在打包的时候在开始位置插入一个short型表示包长(通信层中的包头)
var buffer = sbuf.pack(true);
install
npm install ByteBuffer -g
