CAPEC 描述
An attacker may intercept and log encrypted transmissions for the purpose of analyzing metadata such as packet timing and sizes. Although the actual data may be encrypted, this metadata may reveal valuable information to an attacker. Note that this attack is applicable to VOIP data as well as application data, especially for interactive apps that require precise timing and low-latency (e.g. thin-clients).
CAPEC 信息
前提条件
Use of untrusted communication paths enables an attacker to intercept and log communications, including metadata such as packet timing and sizes.所需技能
These attacks generally require sophisticated machine learning techniques and require traffic capture as a prerequisite.缓解措施
Distort packet sizes and timing at VPN layer by adding padding to normalize packet sizes and timing delays to reduce information leakage via timing.相关弱点

CWE-201 |
Insertion of Sensitive Information Into Sent Data The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor. |
