Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
github.com/renstrom/shortuuid
A Go library that generates concise, unambiguous, URL-safe UUIDs. Based on and
compatible with the Python library
shortuuid
.
Often, one needs to use non-sequential IDs in places where users will see them, but the IDs must be as concise and easy to use as possible. shortuuid solves this problem by generating UUIDs using google/uuid and then translating them to base57 using lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.
package main
import (
"fmt"
"github.com/renstrom/shortuuid"
)
func main() {
u := shortuuid.New() // Cekw67uyMpBGZLRP2HFVbe
}
To use UUID v5 (instead of the default v4), use NewWithNamespace(name string)
instead of New()
.
shortuuid.NewWithNamespace("http://example.com")
It's possible to use a custom alphabet as well, though it has to be 57 characters long.
alphabet := "23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxy="
shortuuid.NewWithAlphabet(alphabet) // u=BFWRLr5dXbeWf==iasZi
Bring your own encoder! For example, base58 is popular among bitcoin.
package main
import (
"fmt"
"github.com/btcsuite/btcutil/base58"
"github.com/renstrom/shortuuid"
"github.com/satori/go.uuid"
)
type base58Encoder struct {}
func (enc base58Encoder) Encode(u uuid.UUID) string {
return base58.Encode(u.Bytes())
}
func (enc base58Encoder) Decode(s string) (uuid.UUID, error) {
return uuid.FromBytes(base58.Decode(s))
}
func main() {
enc := base58Encoder{}
fmt.Println(shortuuid.NewWithEncoder(enc)) // 6R7VqaQHbzC1xwA5UueGe6
}
