The investigation into the breach of security has uncovered the fact that 5.1 million documents were taken from the database that the investigators are in possession of.

When the security compromise was discovered

As a result of the data breach, it has come to light that 29k April worked as a member of the security personnel that the Hacking Team employed. April, in her function as a member of this team, was given the responsibility of investigating reports that a secure internal network had been breached.

The results of the investigation indicate that on April 29, an unknown hacker contacted the system administrators of Hacking Team through email to warn them of a data breach and demand a ransom for the data. The hacker also demanded that a ransom be paid in exchange for the data. This connection enabled the recipient to see the stolen files. As soon as the security team at Hacking Team got this email, they immediately started looking for any signs that their systems had been compromised in any way. They discovered that someone had hacked into their system.

Our security experts reached to the conclusion that there was no indication of a breach in the networks that were maintained by the Hacking Team after conducting an analysis of the information that was obtained and taking into account their findings. We have a strong suspicion that the hacker gained access to April’s network by sending her an email that contained a malicious link or attachment (or by tricking her into clicking on a bogus website address), both of which resulted in the compromise of her laptop and allowed the hacker to gain access to the network. Alternatively, we have a strong suspicion that the hacker gained access to April’s network by sending her an email that contained a harmful link or attachment.


April 29, 2019

The investigation of the event that took place in March 2019 that we have been carrying out is not yet finished. We have determined that there were more than 5.1 thousand lines of code in the release that was made on the 29th of April, whereas there were only 1.4 thousand lines of code in the release that was made on the 4th of April, during a time when we believe an intentional change was made to one or more files related to our test suite that would impact performance. We have determined this by comparing the number of lines of code in each of the two releases. Comparing the total amount of lines of code included in each version allowed us to reach this conclusion.

Impact on the Consumer Base

Impact on the Consumer Base

As a result of the event, a number of customers that depend on Codecov’s services for automated code reviews and testing before deploying new software versions into production settings have expressed worry. These customers use Codecov’s services to prepare for new software version deployments. Before releasing new versions of their software, these clients make advantage of the services that Codecov provides.

Organizations such as IBM and Atlas Sian were quick to react by posting announcements informing users about the actions they were taking as a response to the intrusion in their systems. These announcements informed users about the actions that IBM and Atlas Sian were taking as a response to the intrusion in their systems. These notifications were published as a reaction to the fact that the organizations had identified the vulnerability in their respective computer systems (e.g., reviewing credentials associated with their accounts).

In a similar vein, it has been reported that government agencies such as NASA are currently in the process of reviewing all of the existing contracts that have been signed with Codecov, while at the same time temporarily suspending the signing of any new contracts until further notice. This is being done so that they may analyze any potential vulnerabilities that may exist within their own systems and which may have been exposed as a consequence of this occurrence.

Information about the Data That Have Been Compromised

On the 15th of April, 2021, Codecov disclosed that an unauthorized actor had accessed their Bash Uploader script, which allowed the intruder access to sensitive client data such as API tokens, passwords, and user keys. In addition, the intruder was able to access the script itself. Because of the unauthorized access, the confidentiality of this information was jeopardized.

During additional examination, it was discovered that the systems in issue had been penetrated by attackers throughout the course of a period of three months beginning on the 31st of January, 2021. The time period in question was determined to have begun on the 31st of January, 2021. During this time period, it is thought that they had access to client data; however, there has been no evidence to infer that any consumer data was exploited or stolen in any kind. This idea is developed from pieces of supplementary evidence.

Ongoing investigations explore what caused the event

Since the security flaw was discovered, investigators have been working diligently to determine its breadth and identify the types of information that may have been accessed by those responsible for the incident. Since the security flaw was discovered, investigators have been working diligently to determine its breadth. Investigators have been putting in a lot of effort to find out how widespread the security weakness is since it was discovered.

In order to achieve this aim, Codecov has been conducting interviews with witnesses and examining logs obtained from both its own systems and logs taken from third-party services with whom it interacts (such as cloud hosting providers).

Despite the fact that the investigations are still underway, the investigators have not yet uncovered any proof of malicious conduct or illicit use of client data. Despite this, the investigations are still in their early stages.

Reuters’ April Satter’s Reporting on the Investigation into the Incident

Reuters released a report on April 23, 2021, after they had finished their investigation into the incident and discussed some of the findings and inferences they had drawn as a result of their investigation. The report discussed some of the conclusions they had drawn as a result of their investigation.

According to their sources inside Codecov’s internal security team, the attacker had full access to some parts of Codecov’s computer infrastructure for more than three months. It’s conceivable that the attacker inserted harmful code or obtained access to a considerable quantity of sensitive data without being recognized, both of which are possibilities.

In addition to this, they said that Codecov has discovered more potential entry points for attackers, which are now undergoing further investigation by the security teams of both Codecov and the third-party services with whom they interact (such as cloud hosting providers).


Investigators are very knowledgeable people that have been through a significant amount of training and are able to assist you with your data breach.
