实时的恶意软件进程检测和自动进程查杀

Real-time malware process detection and automated process killing

Matilda Rhode, Pete Burnap, Adam Wedgbury

摘要:

基于边界的检测不再足以减轻恶意软件构成的威胁。这一点很明显,因为防病毒(AV)产品被端点检测和响应(EDR)产品所取代,后者允许对实时机器活动的可见性,而不是依赖于AV来过滤恶意伪影。本文认为,由于某些恶意软件的快速和破坏性,在端点上实时的【形】检测恶意软件需要自动响应。该模型在机器学习动态行为恶意软件检测模型的基础上使用统计过滤,以检测单个恶意进程并杀死那些被认为是恶意的进程。在一项衡量该系统实际影响的实验中,我们发现快速行动的勒索软件被阻止破坏92%的文件,误报率为14%。虽然误报率目前仍然太高,无法按原样采用这种方法,但这些初步结果表明需要一种能够在恶意软件执行开始后几秒钟内采取行动的检测模型;以前的工作尚未解决这个时间尺度。

英文摘要:

Perimeter-based detection is no longer sufficient for mitigating the threat posed by malicious software. This is evident as antivirus (AV) products are replaced by endpoint detection and response (EDR) products, the latter allowing visibility into live machine activity rather than relying on the AV to filter out malicious artefacts. This paper argues that detecting malware in real-time on an endpoint necessitates an automated response due to the rapid and destructive nature of some malware. The proposed model uses statistical filtering on top of a machine learning dynamic behavioural malware detection model in order to detect individual malicious processes on the fly and kill those which are deemed malicious. In an experiment to measure the tangible impact of this system, we find that fast-acting ransomware is prevented from corrupting 92% of files with a false positive rate of 14%. Whilst the false-positive rate currently remains too high to adopt this approach as-is, these initial results demonstrate the need for a detection model which is able to act within seconds of the malware execution beginning; a timescale that has not been addressed by previous work.
