1 Web

FUSE: Finding File Upload Bugs via Penetration Testing
该论文设计并实现了FUSE,这是第一个用于发现服务器端PHP web应用程序中的无限制文件上传(UFU)和不受限制的可执行文件上传(UEFU)漏洞的渗透测试工具。FUSE的目标是生成上传请求;每个请求都会成为一个可触发UFU或UEFU漏洞的攻击载荷。作者们通过精心设计对标准上传请求进行了改变,解决了一些技术挑战,使得改变后的操作可以绕过内容过滤检查,并且不会篡改上传文件的执行。FUSE发现了30个以前未报告的UEFU漏洞,包括33个真实web应用程序中的15个cve,从而证明了它通过文件上传查找代码执行错误的有效性。

10 Side Channels

ABSynthe: Automatic Blackbox Side-channel Synthesis on Commodity Microarchitectures
该论文提出了一种以目标程序和微体系结构为输入,自动合成网络侧信道的系统ABsynthe。关键的见解是,通过限制作者自己使用(通常在核心上)基于竞争的侧通道,可以将目标CPU微体系结构视为一个黑匣子,从而实现自动化。为了使ABsynthe成为可能,作者为各种x86_64微体系结构自动生成了泄漏映射。为了利用优化后的指令序列来恢复秘密信息,ABsynthe依赖于递归神经网络来制造实用的侧信道攻击来恢复秘密比特流。评估表明,与目前针对单个组件的基于竞争的攻击相比,Absynth可以同时利用多个组件上的竞争来合成更好的攻击。此外,Absynth实现的自动化允许在本机和虚拟化环境中对四个不同的加密软件目标合成各种微体系结构的跨线程攻击。

Revisiting Leakage Abuse Attacks
该论文以多种方式重新审视了泄漏滥用攻击。作者首先强调了众所周知的IKK和Count攻击的一些实际限制和假设。然后,作者设计了四种新的泄漏滥用攻击,它们依赖于更弱的假设。其中三种攻击都是容量攻击,因为它们只利用与文档大小相关的泄漏。作者还介绍了两种容量注入攻击,它们使用对抗性文件添加来恢复查询,甚至可以从基于ORAM的解决方案中恢复查询。作者对所有攻击进行了经验评估,并考虑了许多实验设置,实验结果表明在实际假设下,导致合理恢复率的唯一设置是具有泄漏配置文件的高选择性查询,对于这一特定设置,作者提出了一些建议和对策。

15 Systems Security(5篇)

(Mostly) Exitless VM Protection from Untrusted Hypervisor through Disaggregated Nested Virtualization
该论文介绍了CloudVisor-D,这是一种有效的嵌套虚拟机管理程序设计,同时包含强大的保护和高性能。CloudVisor-D的核心思想是通过将主要的保护逻辑与每个来宾VM隔离到受保护的Guardian-VM中来分解嵌套的虚拟机管理程序。Guardian-VM由嵌套的虚拟机管理程序安全地隔离和保护,并为来宾VM的大多数特权操作提供安全服务。通过利用最新的硬件功能,来宾VM的大多数特权操作都不需要退出嵌套虚拟机管理程序的VM,这是先前设计中性能下降的主要来源。实验评估表明,即使对于I / O密集型基准测试,CloudVisor-D所产生的性能开销也可以忽略不计。

An Observational Investigation of Reverse Engineers’ Processes
该论文的目的是为改进逆向工程工具的交互设计提供见解。作者介绍了反向工程师(N = 16)的半结构化观察访谈研究的结果。每个观察都调查了逆向工程师在探查程序时提出的问题,他们如何回答这些问题以及在整个逆向工程过程中做出的决策。从访谈回复中,作者提取了逆向工程过程的模型,分为三个阶段:概述,子组件扫描和重点实验。随着反向工程师的心理表述变得更加具体,每个分析阶段的结果将进入下一个阶段。作者发现,逆向工程师通常在前两个阶段使用静态方法,而在最后阶段使用动态方法,并在每个阶段都扮演着重要角色,但角色各不相同。基于这些结果,作者为逆向工程工具提供了五种交互设计指南。

18 Side Channel Attacks(6篇)

RELOAD+REFRESH: Abusing Cache Replacement Policies to Perform Stealthy Cache Attacks
该论文指出,如果不改变缓存状态并因此强制对所观察的进程进行驱逐,就不可能观察到共同驻留进程的缓存活动,这一事实有力地帮助了检测。我们证明了这种广泛持有的假设是不正确的。通过巧妙地使用高速缓存替换策略,可以跟踪受害者进程的高速缓存访问而无需强制逐出根据受害者的数据。因此,可以绕过依赖于这些驱逐的在线检测机制,因为它们不会检测到引入的RELOAD + REFRESH攻击,攻击需要对缓存替换策略有深刻的理解。作者提出了一种恢复替换策略的方法,并将其应用于最近五代英特尔处理器。通过进一步经验证明了,在加密实现上,RELOAD+REFRESH的性能与其他广泛使用的缓存攻击相媲美。

Scaling Verifiable Computation Using Efficient Set Accumulators
可验证的外包系统将大量计算任务卸载到远程服务器,但要求远程服务器提供简洁的证明(称为SNARK),以证明服务器正确执行了计算。实际上,状态更新的可验证外包是通过更新Merkle树的叶子,重新计算所得的Merkle根以及使用SNARK证明状态更新正确完成来完成的。该论文将现有技术和新颖技术结合使用,在SNARK内部实现了RSA累加器,并将其用作Merkle树的替代品。作者专门优化了累加器,使其与SNARK兼容。实验表明,与使用Merkle树提交到当前状态的现有方法相比,生成的系统可以大大降低成本。

That Was Then, This Is Now: A Security Evaluation of Password Generation, Storage, and Autofill in Browser-Based Password Managers
该论文指出,先前的研究已经发现了现有密码管理器中的重大漏洞,特别是在基于浏览器的密码管理器中。但从那时起,已经过去了五年,目前尚不清楚密码管理器是否仍然易受攻击或是否已解决已知的安全问题。为了回答这个问题,作者评估了十三种流行的密码管理器。该评估是对密码管理器中密码生成的首次分析,通过查找几种非随机字符分布,并确定实例,结果其中所生成的密码容易受到在线和离线猜测攻击。对于密码存储和自动填充,作者复制了以前的评估结果,并表明尽管自从先前的评估以来,密码管理器已有所改进,但仍然存在重大。根据结果,作者确定了需要避免的密码管理器,并提供了有关如何改进现有密码管理器的建议。

3 未来值得研究的方向

3.1 研究方向

通过对三个会议的对比与分析,可以看到有关Web、隐私保护、机器学习、侧信道、系统与应用安全、加密、认证、网络安全等方向的论文较多,比较热门,而最近新兴的一些如区块链和加密货币、移动互联安全、硬件安全、用户行为分析、物联网安全等也很热门,所以未来值得研究的方向有:区块链、物联网安全、用户行为分析、移动互联安全、web、隐私保护、机器学习。

4 总结

通过对四大顶会论文的查找与分析,开拓了自己的视野,增长了见识,了解到了许多知识。虽然对只是简单的了解了论文的研究内容,但也算是对目前的主流的方向有了认识。因为之前对一些知识不太了解,再加上自己的英语不好,Emmmm,有些翻译出来的词,真的是看上去有点懵,然后再单独查一下有没有这个词,才能知道是什么。尤其要说的是,一定要尽早完成自己的任务,555555555555,要是不拖着,也不至于多出来156篇论文,(7月1号我看到了USENIX会议的录取列表),大补特补。
