注:调试纯粹属于兴趣和技术研究,请不要用于非法用途.本人不承担因非法使用带来的法律责任

限制:没怎么用,不知道功能有什么限制,不过有时间限制

先用PEID查壳,ASPack 2.12 -> Alexey Solodovnikov,只是一个压缩壳,顺手脱了很顺利,运行,出错了:

CuteDraw 2.0 破解手记

到看雪看了下发现也有人再研究不过没深入,只需要把脱壳后的文件改成CuteDraw.Exe就可以了(晕,还有不能改文件名的),改后可以运行了,不过一运行就自动关闭了,有自效验.

反正慢慢的跟了,也没下什么断点,就是耐心的走,发现一处代码再41f5ea处

CuteDraw 2.0 破解手记 00417636  |.  85C0          test    eax, eax

看着4175F0和4175F5处的两处字符串,很像是CRC的比较,417636比较EAX之后就是一个跳转,把它NOP掉,保存再运行,自效验搞定了

不过程序再别的地方还有检验,一进入主界面就会挂掉,不过没关系了,这里要做的就是分析脱壳后的程序的注册流程,挂不挂不管它:)

点击注册,一段时间后弹出注册失败字样,看上去象个MessageBox,下断点,再注册,没有收获......

还是先看看字符串参考里面有没有什么提示信息,找到一个

UNICODE "http://www.cutedraw.com/reg/activate.php"的字串,看来还有网络验证?下断点,再点击注册,果然停下来了,程序访问该网址,并且通过GET请求参数order_id和machine_id,order_id就是输入的序列号,machine_id因该是每台机器都不同,直接再浏览器里面访问返回"ER104",继续跟程序,程序里面有返回值判断,首先判断返回串里面有没有"ER",有就完了,再根据后面跟的东西不同弹出不同的错误信息,把跳转搞掉让它跳到后面的"OK"字串,OK,提示注册成功了,但是,好像没什么反应啊,界面还是留在注册界面,还是要点击继续试用才能进入主界面,看来此路不通....

想想注册提醒是一启动就弹出来,肯定本地还是有注册信息进行效验,看来这个软件的流程是先通过注册码从网络激活,然后再每次启动的时候都本地比较,感觉怪怪的,其实网络验证也不是那么的可信....废话不多说,找了下相关文件,发现Config目录下有个User.Ini,里面存放的就是注册信息了,于是下断点GetPrivateProfileStringW,运行,找到了读取User配置的位置,还发现使用时间也是存在一个sf.tmp的INI文件里面,改一下时间软件就过期了,或者删掉这个文件软件又可以使用一个月了-_-#.读完User.Ini里面的Pass字段就是好大一长串的注册码效验代码,由于这个东西不太好调试,于是只找关键跳就行了,判断完注册码后软件会比较eax的结果是否为1,不为1就是未激活,所以只要再判断注册码最后一个地方有个

xor eax,eax 改成 mov al,1就OK了

或者还有一种改法,再417951处

CuteDraw 2.0 破解手记 0041794A  |.  E8 11100600   call    00478960
0041794F  |.  85C0          test    eax, eax
00417951  |.  0F85 85000000 jnz     004179DC

改成Jmp 4179DC就OK了,用KEYMAKE做个内存补丁改这一处跳转就行.

最后运行还是显示试用版,不过已经没有激活提示了,如图:

破解完成,再强调如果你要使用该软件,请支持正版

How does MySQL index cardinality affect query performance?Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL: Resources and Tutorials for New UsersApr 14, 2025 am 12:16 AM

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

Real-World MySQL: Examples and Use CasesApr 14, 2025 am 12:15 AM

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.

SQL Commands in MySQL: Practical ExamplesApr 14, 2025 am 12:09 AM

SQL commands in MySQL can be divided into categories such as DDL, DML, DQL, DCL, etc., and are used to create, modify, delete databases and tables, insert, update, delete data, and perform complex query operations. 1. Basic usage includes CREATETABLE creation table, INSERTINTO insert data, and SELECT query data. 2. Advanced usage involves JOIN for table joins, subqueries and GROUPBY for data aggregation. 3. Common errors such as syntax errors, data type mismatch and permission problems can be debugged through syntax checking, data type conversion and permission management. 4. Performance optimization suggestions include using indexes, avoiding full table scanning, optimizing JOIN operations and using transactions to ensure data consistency.

How does InnoDB handle ACID compliance?Apr 14, 2025 am 12:03 AM

InnoDB achieves atomicity through undolog, consistency and isolation through locking mechanism and MVCC, and persistence through redolog. 1) Atomicity: Use undolog to record the original data to ensure that the transaction can be rolled back. 2) Consistency: Ensure the data consistency through row-level locking and MVCC. 3) Isolation: Supports multiple isolation levels, and REPEATABLEREAD is used by default. 4) Persistence: Use redolog to record modifications to ensure that data is saved for a long time.

MySQL's Place: Databases and ProgrammingApr 13, 2025 am 12:18 AM

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL: From Small Businesses to Large EnterprisesApr 13, 2025 am 12:17 AM

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

What are phantom reads and how does InnoDB prevent them (Next-Key Locking)?Apr 13, 2025 am 12:16 AM

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.
