a9t9.com/copyfish – More Information

The company behind the a9t9.com/copyfish site is a legitimate software development vendor called a9t9 SOftware. Recently they reported that computer hackers have been able to abuse their services and have taken control of the Google Chrome browser extension used by their product. The company is based in Germany listed at the following address:

a9t9 Software GmbH
Altrottstrasse 31
Walldorf, 69190, Europe (Germany)
Phone: +49-6227-6989-787

a9t9.com/copyfish notice image

The company posted a blog post notice (July 30 2017) detailing how the attack occured. The first alert that something went wrong was received on Friday (28 July) when an a9t9 Software team member received an email message that appears to have been sent by Google. It was a Chrome Web Store notification that requested the company to update their extension or else it would be removed from the software repository. This lead to a password prompt where the developer entered the account credentials. Later it was discovered that this is a phishing site that had just overtaken the main developer account of the company. This is also the source of the malicious browser extensions. The criminals behind the attack were able to push an update (version 2.8.5) to the Chrome Web Store which contains malicious code.

a9t9.com/copyfish – Data Collection and Tracking

The primary goal of the dangerous a9t9.com/copyfish browser hijacker is to launch malicious ads and initiate spam attacks against hacker-provided targets. The malicious code can also spam the victim computers with endless banners, pop-ups and other related messages.

As the Google Chrome extensions can modify the the behavior of the application itself it can be used to make the usual changes done by browser hijackers in general:

  1. Browser Settings Modification — Browser hijackers like Copyfish can modify essential settings on the victim web browsers. Typically the intent is to redirect the victim to a hacker-controlled page or service that can inflict further damage to them. The most popular values are modiifed to reflect the hacker–provided address: default home page, search engine and tabs page. Advanced threats can also change security settings and reroute the traffic through hacker-provided gateways.
  2. Information Harvesting — The browser extension can harvest all data stored in the web browser. This includes all form data, stored cookies, history, preferences, passwords, account credentials and bookmarks. The collected data can be used to perform identity theft and financial crimes.
  3. Deliver Additional Malware — Malicious extensions are usually a popular method for spreading additional viruses of all types to the infected computers.

The a9t9.com/copyfish browser hijacker might be further updated with other features as the legitimate software developers have lost control to the Chrome Web Store instance. After the incident has been reported to Google, it has been removed from the software repository. However this does not eliminate the possibility of having the malware code posted in other extensions available on the platform as well as other hacker-controlled sites.

Note! This incident that computer users should not trust extensions even if they appear as being posted by a legitimate company. The hacked Google Chrome browser extensions is merely a detected instance, at any time criminals can take over control other plugins using this or another tactic.
