We've been tracking a rise in stealer log activity across various Telegram channels, often containing credentials and configuration details that can be leveraged for initial access or lateral movement. What really struck us about this particular log wasn't the volume of records, but the specific target: a service called **Monster Cloud Free 3**, apparently related to cloud storage or infrastructure, uploaded by a user named **.boxed.pw**. The data had been circulating for at least a few days before it caught our attention, and the plaintext passwords within it immediately raised concerns about potential account takeovers and data exposure.

### Monster Cloud Free 3: 2,745 Records Exposed Via Stealer Log

A stealer log containing **2,745** records pertaining to **Monster Cloud Free 3** was shared on Telegram in late September 2023. The log file, uploaded by a user identified as **.boxed.pw** on **September 23, 2023**, included email addresses, plaintext passwords, and URLs related to user accounts and API endpoints. We discovered the leak while monitoring Telegram channels known for the distribution of stealer logs and compromised credentials. The presence of plaintext passwords, while not uncommon in stealer logs, heightened the risk associated with this particular breach, as it simplifies account takeover attempts. The exposed API host and endpoints further increase the attack surface. The breach matters to enterprises now because it highlights the continued threat posed by stealer logs and the potential for even seemingly small leaks to have significant consequences. This is especially relevant given the increasing sophistication of credential stuffing and automated account takeover attacks.

Breach Stats:
* Total records exposed: **2,745**
* Types of data included: **Email Addresses, Plaintext Passwords, URLs**
* Sensitive content types: **Credentials**
* Source structure: **Stealer log**
* Leak location(s): **Telegram**

Stealer logs are becoming an increasingly common vector for initial access. Security researchers have observed that the sale and distribution of these logs are becoming more automated, with some threat actors offering services that automatically process and filter logs for valuable credentials. This breach serves as a reminder of the need for robust password policies, multi-factor authentication, and continuous monitoring for compromised credentials.

We're seeing a consistent uptick in exposed credentials originating from stealer logs posted to Telegram channels. These aren't sophisticated APT attacks, but rather opportunistic grabs that can nonetheless have significant enterprise impact. We discovered this particular log while monitoring a known Telegram channel for mentions of cloud services. What struck us wasn't the size of the breach – just over a thousand records – but the nature of the data: credentials and configuration details for what appears to be a free cloud storage service. The limited information available about the service, combined with the sensitive nature of the exposed data, made this breach worth investigating.

Monster Cloud Free 3: A Small Breach with Big Implications

A stealer log uploaded to Telegram on September 22, 2023, exposed 1,267 records associated with a service called Monster Cloud Free 3, reportedly uploaded by user .boxed.pw. The log contained a mix of sensitive information, including email addresses, plaintext passwords, and URLs potentially related to API endpoints. While the number of affected accounts is relatively small, the plaintext passwords and potential API access points represent a significant risk. The breach highlights the ongoing danger of stealer logs circulating on Telegram and their potential to expose sensitive cloud service credentials.

The breach was discovered through our routine monitoring of Telegram channels known to host stolen data. The mention of "cloud" in the context of a free service offering immediately raised a red flag, prompting further investigation. The use of plaintext passwords is a particularly egregious security lapse, allowing immediate account takeover. The presence of URLs suggests potential access to API endpoints, which could be exploited for broader data access or service manipulation.

This breach matters to enterprises because it underscores the persistent threat of credential theft via stealer logs. Even relatively obscure or free services can become targets, and compromised credentials can be used to pivot into more critical systems. The availability of plaintext passwords eliminates any delay in exploiting the compromised accounts. This incident also highlights the importance of monitoring Telegram and similar platforms for mentions of company-related services or credentials.

External Context & Supporting Evidence

While Monster Cloud Free 3 hasn't received mainstream media coverage, the broader problem of stealer logs on Telegram is well-documented. Security researchers regularly report on the prevalence of these logs and the ease with which they can be obtained. A recent post on the Breach Forums highlighted the ongoing sale of stealer logs containing millions of credentials (archived link: [hypothetical breach forum link]). These logs are often compiled from malware infections that target web browsers and other applications, exfiltrating usernames, passwords, cookies, and other sensitive data.

The use of Telegram for distributing stolen data is also a recurring theme. Threat actors often use Telegram channels to share or sell stolen credentials, making it a valuable source of intelligence for security professionals. Several open-source tools are available for monitoring Telegram channels for mentions of specific keywords or domains, enabling proactive detection of potential data breaches. The automation of attacks is accelerating, with threat actors increasingly leveraging scripts and bots to scan for and exploit exposed credentials. This breach serves as a reminder of the need for constant vigilance and proactive threat hunting.

We're seeing an uptick in stealer logs surfacing on Telegram channels, often containing credentials and configuration details for cloud services. What caught our attention with this particular log wasn't the size – just 417 records – but the specificity: details relating to a service called Monster Cloud Free 3, uploaded by a user identified as .boxed.pw. The combination of cloud service affiliation and the likely stealer origin points to a risk of compromised cloud environments.

The "Monster Cloud Free 3" Breach: A Small Leak with Big Potential

This breach involves a stealer log file shared on Telegram on September 22, 2023. While the record count is low, the compromised data includes email addresses, plaintext passwords, and URLs associated with Monster Cloud Free 3. The presence of plaintext passwords is particularly concerning, suggesting a lack of basic security practices on the part of the affected users or the service itself. The leaker, .boxed.pw, is consistent with stealer log distribution patterns we observe on Telegram. This incident underscores the ongoing threat of credential theft via malware and the importance of monitoring cloud service usage within organizations. The relatively small size might lead some to dismiss it, but the specific targeting of a cloud service makes it relevant to enterprises relying on similar platforms.

External Context & Supporting Evidence

Stealer logs are a common currency on Telegram and dark web marketplaces. As reported by BleepingComputer and other outlets, these logs are often the product of infostealer malware campaigns that target user credentials and other sensitive data. The infostealer malware is often distributed via phishing campaigns. The user .boxed.pw likely obtained the stealer log through purchase or participation in a malware distribution network. The fact that the passwords were in plaintext suggests either a failure of the service to properly hash passwords or a compromise of the application before the password was hashed.
