Rogue Developer Infects Widely Used NodeJS Module to Steal Bitcoins

A widely used third-party NodeJS module with nearly 2 million downloads a week was compromised after one of its open-source contributor gone rogue, who infected it with a malicious code that was programmed to steal funds stored in Bitcoin wallet apps.

The Node.js library in question is "Event-Stream," a toolkit that makes it easy for developers to create and work with streams, a collection of data in Node.js — just like arrays or strings.

The malicious code detected earlier this week was added to Event-Stream version 3.3.6, published on September 9 via NPM repository, and had since been downloaded by nearly 8 million application programmers.

Event-Stream module for Node.js was originally created by Dominic Tarr, who maintained the Event-Stream library for a long time, but handed over the development and maintenance of the project several months ago to an unknown programmer, called "right9ctrl."

Apparently, right9ctrl gained Dominic's trust by making some meaningful contributions to the project.

After gaining access to the library, the new rightful maintainer "Right9ctrl" released Event-Stream version 3.3.6, containing a new library, called Flatmap-Stream, as a dependency, which was specifically crafted for the purposes of this attack and includes the malicious code.

Since the flatmap-stream module was encrypted, the malicious code remained undetected for more than 2 months until Ayrton Sparling (FallingSnow), a computer science student at California State University, flagged the issue Tuesday on GitHub.

After analyzing the obfuscated code and encrypted payload, open source project manager NPM which hosted event-stream found that the malicious module has been designed to target people using BitPay's open-source bitcoin wallet app, Copay, a company that incorporated event-stream into its app.

The malicious code attempted to steal digital coins stored in the Dash Copay Bitcoin wallets—distributed through the Node Package Manager (NPM)—and transfer them to a server located in Kuala Lumpur.

Officials from NPM—the open source project manager that hosted event-stream code library—removed the backdoor from NPM's listing on Monday this week.

BitPay also published an advisory saying Copay versions 5.0.2 through 5.1.0 were affected by the malicious code and that users with these versions installed should avoid running or opening the app until they install Copay version 5.2.0.

"Users should assume that private keys on affected wallets may have been compromised, so they should move funds to new wallets (v5.2.0) immediately," BitPay says in the advisory.

"Users should first update their affected wallets (5.0.2-5.1.0) and then send all funds from affected wallets to a brand new wallet on version 5.2.0, using the Send Max feature to initiate transactions of all funds."

BitPay also says that its team continues to investigate this issue and the extent of the vulnerability to know whether the malicious code was ever exploited against Copay users.

BitPay assures its users that the BitPay app was not vulnerable to the malicious code.

Tr0ll 1.0 – Vulnhub CTF Challenge Walkthrough

Tr0ll 1.0 is an intentionally vulnerable machine, which is more of a CTF like type than real world scenario. Nevertheless, this machine has its own difficulties and you can learn some new stuff from it. So, let’s start. Enumeration Phase Let’s first run netdiscover to find the IP of our machine. netdiscover -r 192.168.1.1/24 After that, we run our typical nmap scan to see the open ports in the machine. nmap -A -sS -Pn -vv [target] Great we see many interesting stuff here. First of all, there is an open FTP port and we can connect to it with anonymous access . Also there is an open http port, we will run a nikto scan for it. The ssh port will be valuable later. From the nikto scan we got an interesting /secret/ folder. When we get inside, we can understand why the machine got this name. Nothing interesting here, as you can see. we got trolled Let’s connect to the ftp server. When we get asked for the username we type ‘ anonymous ‘ and we l

Uber fined $1.1 million by UK and Dutch regulators over 2016 data breach

British and Dutch data protection regulators Tuesday hit the ride-sharing company Uber with a total fine of $1,170,892 (~ 1.1 million) for failing to protect its customers’ personal information during a 2016 cyber attack involving millions of users. Late last year, Uber unveiled that the company had suffered a massive data breach in October 2016, exposing names, email addresses and phone numbers of 57 million Uber riders and drivers along with driving license numbers of around 600,000 drivers. Besides this, it was also reported that instead of disclosing the breach at the time, the company paid $100,000 in ransom to the two hackers with access to the stolen data in exchange for keeping the incident secret and deleting the information. Today Britain’s Information Commissioner’s Office (ICO) fined Uber 385,000 pounds ($491,102), while the Dutch Data Protection Authority (Dutch DPA) levied a 600,000 euro ($679,790) penalty on Uber for failing to protect the personal informa
