系统安全防护措施建议：
1.多台机器，不要使用相同的账号和口令
2.登录口令要有足够的长度和复杂性，并定期更换登录口令
3.重要资料的共享文件夹应设置访问权限控制，并进行定期备份
4.定期检测系统和软件中的安全漏洞，及时打上补丁。
5.定期到服务器检查是否存在异常。
6.安装安全防护软件，并确保其正常运行。
7.从正规渠道下载安装软件。
8.对不熟悉的软件，如果已经被杀毒软件拦截查杀，不要添加信任继续运行。
9.保存良好的备份习惯，尽量做到每日备份，异地备份。

标题：.wstop扩展名勒索数据库恢复

操作系统文件被加密成.[[gmtaP2R5]].[[dataserver@airmail.cc]].wstop扩展名,类似

运行的oracle数据库文件,从名称上看没有被加上明显的后缀名

通过winhex打开文件分析,虽然文件名称没有改变,但是文件依旧被破坏

通过专业工具检测具体破坏情况,每个文件破坏三段,破坏24个block左右

因为损坏block较少,这种情况,可以通过我开发的Oracle数据文件勒索加密工具进行处理,然后open数据库

类似勒索病毒预防建议：
1. 教育和培训：提高用户的网络安全意识非常重要。通过定期的网络安全培训和教育，向用户传达有关勒索病毒及其传播方式的知识，让他们能够警惕潜在的威胁，并学会如何正确应对可疑的电子邮件、链接和附件。
2. 更新和维护：及时更新操作系统、应用程序和安全软件，以修补已知的漏洞，并确保系统能够及时获取最新的安全补丁。此外，定期进行系统维护和检查，确保系统的安全配置和设置。
3. 备份数据：定期备份重要的数据和文件，并将备份存储在安全的离线或云存储中。确保备份是完整的、可靠的，并且能够及时恢复，以便在发生勒索病毒感染或其他数据丢失事件时能够快速恢复数据。
4. 网络安全工具：使用可信赖的网络安全工具，包括防病毒软件、防火墙、入侵检测系统等，以提高系统的安全性和防护能力。定期对系统进行全面的安全扫描和检测，及时发现并清除潜在的威胁。
5. 访问控制：实施严格的访问控制措施，限制用户对系统和文件的访问权限，避免使用管理员权限进行日常操作，以减少恶意软件感染的风险。此外，定期审查和更新访问控制策略，确保系统安全性得到有效维护。
6. 应急响应计划：制定和实施应急响应计划，明确团队成员的责任和任务，建立应对勒索病毒和其他安全事件的应急响应流程，以最大程度地减少损失并快速恢复业务正常运营。

::: Greetings :::

Little FAQ:

.1. 
Q: Whats Happen?
A: Your files have been encrypted. The file structure was not damaged, we did everything possible so that this could not happen.

.2. 
Q: How to recover files?
A: If you wish to decrypt your files you will need to pay us.

.3. 
Q: What about guarantees?
A: Its just a business. We absolutely do not care about you and your deals, except getting benefits. If we do not do our work and liabilities - nobody will cooperate with us. Its not in our interests.
To check the ability of returning files, you can send to us any 2 files with SIMPLE extensions(jpg,xls,doc, etc... not databases!) and low sizes(max 1 mb), we will decrypt them and send back to you. That is our guarantee.

.4.
Q: How to contact with you?
A: You can write us to our mailboxes: tsai.shen@mailfence.com or nicetomeetyou@onionmail.org

.5.
Q: How will the decryption process proceed after payment?
A: After payment we will send to you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files.

.6.
Q: If I don抰 want to pay bad people like you?
A: If you will not cooperate with our service - for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice - time is much more valuable than money.



:::BEWARE:::
DON'T try to change encrypted files by yourself! 
If you will try to use any third party software for restoring your data or antivirus solutions - please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.

通过分析确认该文件就是头部32个block被破坏,因为oracle数据库中前面32个block是不含业务数据(主要是文件头和位图信息),通过自研的Oracle数据文件加密勒索恢复工具对其进行修复

重建ctl之后,open数据库查询用户创建时间证明库是直接open成功的

有可能数据库被勒索加密扩展名为:.[metro777@cock.li].Elbie,以前有过类似恢复.mkp和.Elbie勒索加密数据库可恢复
metro777@cock.li.Elbie

通过工具分析文件损坏情况

对于这种文件损坏较少的oracle数据文件,可以通过自研的Oracle数据文件勒索恢复工具直接进行恢复

然后直接打开数据库,使用expdp导出数据(由于system文件中损坏的少量block刚好是i_col3这个index,对其进行处理之后,导出成功)
