Malicious npm Package Targets Solana Developers and Hijacks Funds
A malicious npm package targets Solana developers, rerouting funds in 2% of transactions to a hardcoded address.
Localization package provides tools for multilateration and triangulation in 2D
,3D
and on earth surface
.
The current model of the earth, supported by the package, is called Earth1
.
Earth1 models the earth as an ideal sphere having radius of 6378.1 kilometers.
The package has been tested with python2.7 and python3.6. Use pip to install the package:
pip install localization
Typical usage of the package is:
import localization as lx
To initilaize new localization Project use:
P=lx.Project(mode=<mode>,solver=<solver>)
Currently three modes are supported:
Also three solvers can be used:
To add anchors to the project use:
P.add_anchor(<name>,<loc>)
where name denote user provided label of the anchor and is the location of the anchor provided in tuple, e.g., (120,60).
To add target use:
t,label=P.add_target()
t is the target object and label is the package provided label for the target.
Distance measurements must be added to target object like:
t.add_measure(<anchore_lable>,<measured_distance>)
Finally running P.solve() will locate all targets. You can access the estimated location of the target t by t.loc.
t.loc is a point object. Point object B
has x
,y
,z
coordinates available by B.x
, B.y
, B.z
respectively.
Here is a sample use of the package for three anchors and one target scenario:
import localization as lx
P=lx.Project(mode='2D',solver='LSE')
P.add_anchor('anchore_A',(0,100))
P.add_anchor('anchore_B',(100,100))
P.add_anchor('anchore_C',(100,0))
t,label=P.add_target()
t.add_measure('anchore_A',50)
t.add_measure('anchore_B',50)
t.add_measure('anchore_C',50)
P.solve()
# Then the target location is:
print(t.loc)
