“My little birds are in all places, even all the way through the North, they whisper to me the strangest tales.” – Lord Varys
Whispers is a static code research software designed for parsing fairly numerous commonplace knowledge codecs searching for hardcoded credentials and dangerous purposes. Whispers can run all the way through the CLI or you’ll be able to combine it on your CI/CD pipeline.
- API tokens
- AWS keys
- Non-public keys
- Hashed credentials
- Authentication tokens
- Unhealthy purposes
- Delicate data
Whispers is meant to be a structured textual content parser, not a code parser.
The next steadily used codecs are in recent years supported:
- conf / ini
- Shell scripts
Python3 data are parsed as ASTs because of local language toughen.
Declaration & Project Codecs
The next language data are parsed as textual content, and checked for commonplace variable declaration and task patterns:
- AWS credentials data
- JDBC connection strings
- Jenkins config data
- SpringFramework Beans config data
- Java Properties data
- Dockercfg private registry auth data
- Github tokens

There are a number of configuration imaginable alternatives to be had in Whispers. It’s imaginable to incorporate/exclude ends up in maintaining with record trail, key, or cost. File trail specs are interpreted as globs. Keys and values settle for no longer strange expressions and reasonably numerous other different parameters. There’s a default configuration record integrated that can be used for individuals who don’t supply a customized one.
config.yml will have to have the next construction:
- "**/take a look at/**/*"
message: Whispers from the North
regex: (Aria|Ned) Stark
The quickest way to tweak detection (ie: take away false positives and undesirable effects) is to duplicate the default config.yml into a brand new record, adapt it, and transfer it as a subject to Whispers.
whispers --config config.yml --rules starks src/record/or/dir
Rules specify the true issues that are meant to be pulled out from key-value pairs. There are a number of commonplace ones that come integrated, reminiscent of AWS keys and passwords, on the other hand the software is made to be simply expandable with new tips.
- Customized tips can be outlined in the principle config record beneath
- Customized tips can be added to whispers/tips
rule-id: # distinctive rule identify
description: Values formatted like AWS Consultation Token
message: AWS Consultation Token # file will display this message
severity: BLOCKER # one among BLOCKER, CRITICAL, MAJOR, MINOR, INFO
key: # specify key construction
ignorecase: True # case-insensitive matching
cost: # specify cost construction
ignorecase: False # case-sensitive matching
minlen: 270 # cost is at least this lengthy
isBase64: True # cost is base64-encoded
isAscii: False # cost is binary knowledge when decoded
isUri: False # cost isn't formatted like a URI
similar: 0.35 # most allowed similarity between key and price
# (1.0 being precisely the similar)
All parsing capability is performed by way of plugins. Each and every plugin implements a category with the
pairs() implies that runs by way of data and returns the key-value pairs to be checked with tips.
def pairs(self, record):
yield "key", "cost"
