Binance Hacker attacks do not begin with some complex attack on the front door of the exchange. According to a preliminary investigation timeline, the attackers first infiltrated employees, stole credentials, and ultimately gained access to the platform's internal wallet signing service.

This process has raised concerning internal security issues. Three engineers became part of the attack chain, ultimately leading to unauthorized asset transfers.

Binance Hacker attacks begin with tampered-down download files

It is alleged that the troubles first appeared in June. At that time, Engineer A from Wallet DevOps downloaded a tampered Homebrew installer while configuring a AI coding tool. Binance discovered this incident, replaced the device, and rotated the credentials. However, the relevant information of this engineer and his colleagues has been exposed.

Then September arrived. Engineer B downloaded a malicious code repository during what seemed to be a fake job interview, which led to his work computer being compromised.

Stolen credentials opened the internal doors.

On October 20th, attackers allegedly used compromised devices and an internal AI tool to take control of engineers A and C. They also discovered a container deployment permission token on engineer A's computer.

This operation was further escalated on October 29th. The attackers accessed Engineer C's device, used credentials stolen from location A to deploy a container, and executed malicious scripts. This process ultimately allowed them to initiate unauthorized transfers through the internal wallet signing service of Binance.

Claims regarding the Google advertisement have not been confirmed yet.

Another commentator stated that this approximately $6 billion Binance hacking incident stemmed from a developer clicking on a malicious Google advertisement, and believed that Google should be held responsible for it.

However, this preliminary timeline does not confirm this association. It describes the tampered installation programs and malicious repositories, rather than the confirmed Google advertising entry points.

This distinction is very important. The timeline of the hacker attack Binance points to the compromised engineers, the exposed credentials, and the deployment permissions, which are considered key aspects of the attack. Blaming the advertising platform without evidence may cover up specific security failures that investigators are still reviewing.
