勒索病毒代码分析(勒索病毒源代码样本)

这是什么,两次出现这个蓝屏了,是不是中了最近的那个勒索病毒

不是“永恒之蓝”勒索病毒。

0x0000001E (等同于新式蓝屏表示代码 BCCode:1e)

错误名称 0x0000001E:KMODE_EXCEPTION_NOT_HANDLED

故障分析 0x0000001E 错误表示Windows检测到一个非法的或未知的进程指令。这个错误一般是因为内存发生故障引起的,或者与0x0000000A错误相似,表示在内核模式中存在以过高的进程内部请求级别(IRQL)访问其没有权限访问的内存地址。 如果遇到0x0000001E错误,建议首先检查一下软件及硬件兼容性,看看最近有没有安装过新的应用软件、硬件设备或驱动程序。如果有的话,请将最近安装过的软件及硬件逐一卸载,看看问题能否解决;其次,请检查一下蓝屏故障提示中是否提到问题是由Win32K.SYS文件引起的,如果是的话,那么很可能是远程控制类软件引起的故障。

.

检查系统日志-按Win+R键或点击屏幕左下角"开始"运行输入:EventVwr.msc(也可以打开控制面板管理工具事件查看器)打开后.点击"自定义视图管理事件"和"Windows日志"下各项日志,双击打开红色错误和黄色警告项,查看具体的报错信息了.然后根据具体的报错信息进行相应的修复.涉及到第三方软件的错误,就卸载该软件.属于系统错误可以尝试手动修复或系统还原.注销或重启电脑.再进系统看看是否已恢复系统正常.如果依然报错,无法修复的话,可以使用系统备份恢复系统初始状态,或者彻底重装操作系统.

第一,什么是电脑病毒?什么又是勒索病

计算机病毒(电脑病毒)是编制者在计算机程序中插入的破坏计算机功能或者数据的代码,能影响计算机使用,能自我复制的一组计算机指令或者程序代码。

计算机病毒具有传播性、隐蔽性、感染性、潜伏性、可激发性、表现性或破坏性。计算机病毒的生命周期:开发期→传染期→潜伏期→发作期→发现期→消化期→消亡期。

计算机病毒是一个程序,一段可执行码。就像生物病毒一样,具有自我繁殖、互相传染以及激活再生等生物病毒特征。计算机病毒有独特的复制能力,它们能够快速蔓延,又常常难以根除。它们能把自身附着在各种类型的文件上,当文件被复制或从一个用户传送到另一个用户时,它们就随同文件一起蔓延开来。

勒索病毒(WannaCry),一种“蠕虫式”的勒索病毒软件,大小3.3MB,被人利用泄露的危险漏洞“EternalBlue”(永恒之蓝)进行传播,勒索病毒肆虐,俨然是一场全球性互联网灾难,给广大电脑用户造成了巨大损失。最新统计数据显示,100多个国家和地区超过10万台电脑遭到了勒索病毒攻击、感染。 勒索病毒是自灰鸽子和熊猫烧香以来影响力最大的病毒之一。WannaCry勒索病毒全球大爆发,至少150个国家、30万名用户中招,造成损失达80亿美元,已经影响到金融,能源,医疗等众多行业,造成严重的危机管理问题。中国部分Windows操作系统用户遭受感染,校园网用户首当其冲,受害严重,大量实验室数据和毕业设计被锁定加密。部分大型企业的应用系统和数据库文件被加密后,无法正常工作,影响巨大。

勒索病毒是什么

很难再次有大爆发,首次爆发的根本原因是教育网以及内网单位对445端口的麻痹大意造成的,是防御上的弱B,而非病毒的牛B,有了第一次的教训后没谁还敢轻易开放445端口了,病毒大范围爆发的根本条件已经不具备。

本次爆发的勒索病毒借用了最新的“永恒之蓝”windows攻击工具,使其可以对局域网中所有未防备445端口的开机电脑主动进行感染,具备了之前电脑病毒不具有的主动入侵性,所以才造成大爆发。勒索病毒和其他病毒一样,依旧可以经由网络下载和U盘感染等传统方式入侵计算机,并不是防备了445端口就万无一失。

盗号什么的不必担心,勒索病毒只是强制给你电脑中所有的文档、图片、视频、压缩包等等重要文件进行加密,而且加密强度极高,基本不存在强行解密的可能,对特殊人群的电脑有毁灭性的伤害,而其盈利也正是针对这些特殊人群索要赎金而已。

什么是勒索病毒?

勒索病毒,是一种新型电脑病毒,主要以邮件、程序木马、网页挂马的形式进行传播。该病毒性质恶劣、危害极大,一旦感染将给用户带来无法估量的损失。这种病毒利用各种加密算法对文件进行加密,被感染者一般无法解密,必须拿到解密的私钥才有可能破解。

勒索病毒是什么?

勒索病毒,是一种新型电脑病毒,主要以邮件,程序木马,网页挂马的形式进行传播。该病毒性质恶劣、危害极大,勒索病毒文件一旦进入本地,就会自动运行,同时删除勒索软件样本,以躲避查杀和分析。勒索病毒利用各种加密算法对文件进行加密,要破解若非病毒开发者本人及其团体,必须拿到解密的私钥才有可能破解。

网页挂马

网页挂马就是在网页的源代码中加入一些代码,利用漏洞实现自动下载他的木马到你的机器里

.Cale是什么勒索病毒?

GlobeImposter家族勒索病毒变种,主要以国内公共机构服务器作为攻击对象。据腾讯企业安全技术专家指出,从捕获的传播样本来看,其恶意代码框架和流程是一致的,唯一不同的就是加密文件的后缀名和攻击者的邮箱地址信息。恶意代码样本为了防止被轻易地分析,加密了大多数字符串和一部分API,而加密后的文件后缀将会重命名为.TRUE等。
