Hackers Drain $1.5 Million Bitcoin ATMs Using 0-day Bug



Increase / BATM sold by General Bytes.

common bytes

Hackers siphoned millions of dollars worth of digital coins from cryptocurrency ATMs by exploiting a zero-day vulnerability, leaving customers on the hook for unrecoverable losses, the kiosk maker said.

The robbery involved ATMs sold by General Bytes, a company with several offices around the world. These BATMs, short for bitcoin ATMs, can be installed in stores and other businesses to allow people to exchange bitcoins for other currencies and vice versa. Clients connect BATM to cryptographic application server (CAS) that they can manage, or, until now, General Bytes could manage for them. For reasons that are not entirely clear, BATMs offer an option that allows clients to upload video from a terminal to a CAS using a mechanism known as the master server interface.

I’m going, I’m going, I’m gone

On the weekend General Bytes disclosed that more than $1.5 million worth of bitcoins were withdrawn from CAS operated by the company and clients. To carry out the robbery, an unknown attacker exploited a previously unknown vulnerability that allowed him to use this interface to download and execute a malicious Java application. The actor then emptied various hot wallets of about 56 BTC worth about $1.5 million. General Bytes fixed the vulnerability 15 hours after it became known, but due to the way cryptocurrencies work, the losses were irreparable.

General Bytes officials wrote:

The night of March 17-18 was the most difficult time for us and some of our clients. The entire team is working around the clock to collect all security breach data and are constantly working to resolve all incidents to help customers get back online and continue working with their ATMs as soon as possible. We apologize for what happened, will review all of our security procedures and are currently doing everything we can to keep our affected customers afloat.

The report states that the course of the attack was as follows:

1. An attacker discovered a security vulnerability in the main service interface that BATMs use to upload videos to CAS.

2. The attacker scanned the IP address space managed by the DigitalOcean Ocean cloud host to identify running CAS services on ports 7741, including the General Bytes Cloud service and other BATM operators using their servers in Digital Ocean.

3. Using the vulnerability, an attacker uploaded a Java application directly to the application server used by the administrative interface. The application server is configured by default to run applications in its deployment folder.

After running the malicious application on the server, the attacker was able to (1) access the database, (2) read and decrypt the encrypted API keys needed to access funds in hot wallets and exchanges, (3) transfer funds from hot wallets to the wallet, controlled by an attacker, (4) downloading username and password hashes and disabling 2FA, and (5) accessing terminal event logs and looking for instances where customers scanned private keys at an ATM. The sensitive data in step 5 was registered by older versions of the ATM software.

BATM clients are now on their own

Going forward, General Bytes will no longer operate CAS on behalf of customers, in a release this weekend. This means that terminal owners will have to manage the servers themselves. The company is also collecting data from customers to verify all hack-related losses, conducting internal investigations, and cooperating with authorities in an attempt to identify the perpetrator.

General Bytes said the company has gone through “several security reviews” since 2021, and none of them found a exploited vulnerability. The company is currently seeking additional assistance in securing its BATMs.

The incident highlights the risk of storing cryptocurrencies in wallets available online, commonly referred to as hot wallets. Over the years, attackers who exploit various vulnerabilities in cryptocurrency infrastructures, or trick wallet owners into providing the encryption keys needed to withdraw funds, have been illegally draining untold amounts of digital coins from hot wallets.

Security practitioners have long advised people to store funds in cold wallets, which means they are not directly accessible from the internet. Unfortunately, BATMs and other types of cryptocurrency ATMs generally cannot follow this best practice because terminals must be connected to hot wallets in order for them to make real-time transactions. This means that BATM is likely to remain a prime target for hackers.

Positive Grid Introduces Spark Go Ultra-Portable Enhanced Guitar Amplifier



Positive Grid has a new ultra-portable version of its high-tech Spark guitar amp. Designed for musicians who need a versatile and powerful practice amp, the 3.5″ tall Spark Go works with a companion app loaded with virtual amps, pedals and other effects, and can even flesh out your sound with AI drums and other accompaniments. tools.

Like its predecessors, Spark Go is paired with an iOS/Android app to go far beyond enhancing your strumming and gaming; it digitally enlarges it. It includes 50,000 tones (ranging from boutique to modern), 33 amps and 43 effects and pedals, giving you many new ways to shape your sound. The app can even “jam with you” by listening to your playing and learning from it by creating an appropriate background track. And if you want to learn new tunes, the app can sync with Spotify or Apple Music to display AI-generated chords for the song you hear.

A 2021 review of the Spark Pearl (a larger model in the same line) by Engadget found the app to have some rough edges, including an unconvincing AI drummer. However, the company has had plenty of time to iron this out, so we reserve the right to judge the current iteration until we test it again. After all, you may have heard that generative AI has made some impressive leaps since then.

The amplifier has a solid construction and “extra hard grille” to (at least in theory) live up to its “on the go” brand; Positive Grid says it’s even suitable for pedalboarding. The company suggests laying it flat for omnidirectional sound, or placing it on the edge for “sound in the face.” In addition, it uses computational audio that delivers “surprisingly big, full sound” from its tiny body. (And you can plug in headphones to practice in private.) The amp’s battery supposedly lasts up to eight hours and charges via USB-C. Finally, it supports four presets when you find a mix you want to keep close at hand.

Positive Grid accepts early registration to be notified when Spark Go pre-orders go live. Whenever they open (the company hasn’t announced a date yet), the company will offer the amplifier at an aggressive $109 price point, although it will eventually increase to the recommended $149.
