Fake the Source of Data
Attack Pattern ID: 194 (Standard Attack Pattern Completeness: Stub)Typical Severity: MediumStatus: Draft
+ Description


The attacker provides data under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or it might be an attempt by the attacker to assume the rights granted to another identity. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. Results of the attack vary depending on the details of the attack, but common results include privilege excalation, obfuscation of other attacks, and data corruption/manipulation. This attack represents a subset of the Identity Spoofing and Content Spoofing attacks. Identity spoofing is a broader pattern, including situations where no data is exchange (for example, logging into a computer under an assumed name). Content Spoofing is likewise very similar, but would include cases where there is not an active attempt to fake a data source (for example, appending content onto an existing email message without changing the From field would be considered Content Spoofing, but not Faking the Source of Data since the data source was not faked).

+ Attack Prerequisites

The target application must associate data with its source. This association could be as simple as logging the source of the data (in which case this attack seeks to create a false trail in the log) or the target application could associate some increased level of access with certain identities (in which case an attacker might seek to impersonate those identities in order to increase privileges).

+ Resources Required

Resources required vary depending on the nature of the attack. Possible tools needed by an attacker could include tools to create custom network packets, specific client software, and tools to capture network traffic. Many variants of this attack require no attacker resources, however.
