Breaking News: Massive Cyber Attack on ChatGPT – Over 100,000 User Accounts Compromised by Malicious Malware
A new malware strain can steal sensitive information from popular chatbot platforms, including ChatGPT. Researchers from cybersecurity firm Group-IB discovered the malware on a hacker forum, where it was being sold for $200. The malware can exfiltrate chat logs, user data and tokens, and other sensitive information stored on the infected machine. Over 100,000 ChatGPT accounts have reportedly been compromised by the malware.

According to data from dark web marketplaces, more than 101,000 ChatGPT user accounts have fallen victim to information-stealing malware over the past year.
Group-IB, a cyberintelligence firm, has identified over a hundred thousand info-stealer logs containing ChatGPT accounts on various underground websites. The peak of these attacks was observed in May 2023, when threat actors posted 26,800 new ChatGPT credential pairs.
The Asia-Pacific region was the most targeted, with almost 41,000 compromised accounts between June 2022 and May 2023, followed by Europe with nearly 17,000, and North America with 4,700.

Information stealers are a type of malware that targets account data stored on applications such as email clients, web browsers, instant messengers, gaming services, and cryptocurrency wallets. These malware types are known for stealing credentials saved to web browsers by extracting them from the program’s SQLite database and abusing the CryptProtectData function to reverse the encryption of the stored secrets. The credentials and other stolen data are then packaged into archives called logs and sent back to the attackers’ servers for retrieval.
ChatGPT accounts, alongside email accounts, credit card data, cryptocurrency wallet information, and other more traditionally targeted data types, signify the rising importance of AI-powered tools for users and businesses. With ChatGPT allowing users to store conversations, accessing one’s account could mean gaining insights into proprietary information, internal business strategies, personal communications, software code, and more.
“Many enterprises are integrating ChatGPT into their operational flow,” comments Group-IB’s Dmitry Shestakov. “Employees enter classified correspondences or use the bot to optimize proprietary code. Given that ChatGPT’s standard configuration retains all conversations, this could inadvertently offer a trove of sensitive intelligence to threat actors if they obtain account credentials.”
Due to these concerns, tech giants like Samsung have banned staff from using ChatGPT on work computers, going as far as threatening to terminate the employment of those who fail to follow the policy.
Group-IB’s data indicates that the number of stolen ChatGPT logs has grown steadily over time, with almost 80% of all logs coming from the Raccoon stealer, followed by Vidar (13%) and Redline (7%).

If you input sensitive data on ChatGPT, consider disabling the chat saving feature from the platform’s settings menu or manually delete those conversations as soon as you are done using the tool. However, it should be noted that many information stealers snap screenshots of the infected system or perform keylogging, so even if you do not save conversations to your ChatGPT account, the malware infection could still lead to a data leak.
Unfortunately, ChatGPT has already suffered a data breach, where users saw other users’ personal information and chat queries. Therefore, those working with extremely sensitive information shouldn’t trust inputting it on any cloud-based services, but only on secured locally-built and self-hosted tools.

Did you hear the news? American car rental giant Avis recently informed customers that cybercriminals breached one of its business applications last month and stole some of their personal information.

The company advised those whose personal information was stolen to remain vigilant against threats of identity theft or fraud. They suggested customers do this by regularly reviewing and monitoring their account statements and credit history for any signs of unauthorized transactions or activity and contacting credit reporting agencies if they suspect any unauthorized activity.
Moreover, Avis offered those affected a free one-year membership to Equifax’s credit monitoring service, which provides assistance with identity theft detection and resolution.

DICK’S Sporting Goods Halts Email & Locks Employee Accounts Following Intense Cyberattack
US retailer Dick’s Sporting Goods suffered a cyberattack, prompting the company to shut down employee email accounts and reset passwords. Discover how the attack unfolded and what measures the company is taking to prevent future incidents.
![DICK'S Sporting Goods Halts Email & Locks Employee Accounts Following Intense Cyberattack 18](https://it-services.com/wp-content/uploads/2024/08/DICKS-Sporting-Goods-Halts-Email-Locks-Employee-Accounts-Following.jpg)
Last Wednesday, DICK’S Sporting Goods, the largest chain of sporting goods retail stores in the United States, discovered a cyberattack that exposed confidential information. With $12.98 billion in revenue in 2023 and over 857 stores across the country, this breach impacts a significant number of people.
Responding to the Cyberattack
In a filing with the U.S. Securities and Exchange Commission (SEC), DICK’S has hired outside cybersecurity experts to help contain the security breach and assess the impact. The company stated, “On August 21, 2024, the Company discovered unauthorized third-party access to its information systems, including portions of its systems containing certain confidential information.”
As soon as the incident was detected, DICK’S activated its cybersecurity response plan and engaged external cybersecurity experts to investigate, isolate, and contain the threat.
Keeping Information Under Wraps
According to an anonymous source, the company has been tight-lipped about the breach and has instructed employees not to discuss it publicly or put any information in writing. The same source revealed that email systems had been shut down, likely to isolate the attack, and all employees were locked out of their accounts. IT staff is now manually validating employees’ identities on camera before granting access to internal systems.
In an internal memo, DICK’S informed employees that most of them no longer have access to their systems due to a “planned activity” and that team leaders will contact them via personal email or text for further instructions.
Business Operations Unaffected
Phone lines at local stores are currently down due to the incident, but the company has reported no disruption to their business operations to date. In their SEC filing, DICK’S stated, “The Company has also notified federal law enforcement. The Company has no knowledge that this incident has disrupted business operations. The Company’s investigation of the incident remains ongoing.”
Although the company believes the incident is not material at this point, the investigation is still in progress, and the full impact remains to be seen.
