GitHub | Breaking Cybersecurity News | The Hacker News

Threat actors are increasingly making use of GitHub for malicious purposes through novel methods, including abusing secret Gists and issuing malicious commands via git commit messages. "Malware authors occasionally place their samples in services like Dropbox, Google Drive, OneDrive, and Discord to host second stage malware and sidestep detection tools," ReversingLabs researcher Karlo Zanki  said  in a report shared with The Hacker News. "But lately, we have observed the increasing use of the GitHub open-source development platform for hosting malware." Legitimate public services are  known  to be  used  by  threat actors  for hosting malware and acting as  dead drop resolvers  to fetch the actual command-and-control (C2) address. While using public sources for C2 does not make them immune to takedowns, they do offer the benefit of allowing threat actors to easily create attack infrastructure that's both inexpensive and reliable. This technique is sneaky

Let's begin with a thought-provoking question: among a credit card number, a social security number, and an Electronic Health Record (EHR),  which commands the highest price on a dark web forum?   Surprisingly, it's the EHR, and the difference is stark: according to a  study , EHRs can sell for up to $1,000 each, compared to a mere $5 for a credit card number and $1 for a social security number. The reason is simple: while a credit card can be canceled, your personal data can't. This significant value disparity underscores why the healthcare industry remains a prime target for cybercriminals. The sector's rich repository of sensitive data presents a lucrative opportunity for profit-driven attackers. For 12 years running, healthcare has faced the highest average costs per breach compared to any other sector.  Exceeding an average of $10 million per breach , it surpasses even the financial sector, which incurs an average cost of around $6 million. The severity of this iss

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

New research has found that over 15,000 Go module repositories on GitHub are vulnerable to an attack called repojacking. "More than 9,000 repositories are vulnerable to repojacking due to GitHub username changes," Jacob Baines, chief technology officer at VulnCheck,  said  in a report shared with The Hacker News. "More than 6,000 repositories were vulnerable to repojacking due to account deletion." Collectively, these repositories account for no less than 800,000 Go module-versions. Repojacking , a portmanteau of "repository" and "hijacking," is an attack technique that allows a bad actor to take advantage of account username changes and deletions to create a repository with the same name and the pre-existing username to stage open-source software supply chain attacks. Earlier this June, cloud security firm Aqua  revealed  that millions of software repositories on GitHub are likely vulnerable to the threat, urging organizations that undergo

The title of this article probably sounds like the caption to a meme. Instead, this is an actual problem GitGuardian's engineers had to solve in implementing the mechanisms for their new  HasMySecretLeaked service . They wanted to help developers find out if their secrets (passwords, API keys, private keys, cryptographic certificates, etc.) had found their way into public GitHub repositories. How could they comb a vast library of secrets found in publicly available GitHub repositories and their histories and compare them to your secrets without you having to expose sensitive information? This article will tell you how. First, if we were to set a bit's mass as equal to that of one electron, a ton of data would be around 121.9 quadrillion petabytes of data at standard Earth gravity or $39.2 billion billion billion US dollars in MacBook Pro storage upgrades (more than all the money in the world). So when this article claims GitGuardian scanned a "ton" of GitHub public commit data, t

Cybersecurity researchers are warning of publicly exposed Kubernetes configuration secrets that could put organizations at risk of supply chain attacks. "These encoded Kubernetes configuration secrets were uploaded to public repositories," Aqua security researchers Yakir Kadkoda and Assaf Morag  said  in a new research published earlier this week. Some of those impacted include two top blockchain companies and various other fortune-500 companies, according to the cloud security firm, which leveraged the GitHub API to fetch all entries containing .dockerconfigjson and .dockercfg types that  store credentials  for accessing a container image registry. Of the 438 records that potentially held valid credentials for registries, 203 records – about 46% – contained valid credentials that provided access to the respective registries. Ninety-three of the passwords were manually set by individuals, as opposed to the 345 that were computer-generated. "In the majority of cases, these creden

A new ongoing campaign dubbed  EleKtra-Leak  has set its eyes on exposed Amazon Web Service (AWS) identity and access management (IAM) credentials within public GitHub repositories to facilitate cryptojacking activities. "As a result of this, the threat actor associated with the campaign was able to create multiple AWS Elastic Compute (EC2) instances that they used for wide-ranging and long-lasting cryptojacking operations," Palo Alto Networks Unit 42 researchers William Gamazo and Nathaniel Quist  said  in a technical report shared with The Hacker News. The operation, active since at least December 2020, is designed to mine Monero from as many as 474 unique Amazon EC2 instances between August 30 and October 6, 2023. A standout aspect of the attacks is the automated targeting of AWS IAM credentials within four minutes of their initial exposure on GitHub, indicating that threat actors are  programmatically cloning and scanning the repositories  to capture the exposed keys.

GitHub has  announced  an improvement to its secret scanning feature that extends validity checks to popular services such as Amazon Web Services (AWS), Microsoft, Google, and Slack. Validity checks,  introduced  by the Microsoft subsidiary earlier this year, alert users whether exposed tokens found by  secret scanning  are active, thereby allowing for effective remediation measures. It was first enabled for GitHub tokens. The cloud-based code hosting and version control service said it intends to support more tokens in the future. To toggle the setting, enterprise or organization owners and repository administrators can head to Settings > Code security and analysis > Secret scanning and check the option "Automatically verify if a secret is valid by sending it to the relevant partner." Earlier this year, GitHub also  expanded  secret scanning alerts for all public repositories and announced the  availability of push protection  to help developers and maintainers pr

A new deceptive campaign has been observed hijacking GitHub accounts and committing malicious code disguised as Dependabot contributions with an aim to steal passwords from developers. "The malicious code exfiltrates the GitHub project's defined secrets to a malicious C2 server and modify any existing javascript files in the attacked project with a web-form password-stealer malware code effecting any end-user submitting its password in a web form," Checkmarx  said  in a technical report. The malware is also designed to capture GitHub secrets and variables to a remote server by means of a GitHub Action. The software supply chain security firm said it observed the atypical commits to hundreds of public and private GitHub repositories between July 8 and 11, 2023. It has emerged that the victims had their GitHub personal access tokens stolen and used by the threat actors to make falsified code commits to users' repositories by posing as Dependabot. Dependabot  is d

Microsoft on Monday said it took steps to correct a glaring security gaffe that led to the exposure of 38 terabytes of private data. The leak was discovered on the company's AI GitHub repository and is said to have been inadvertently made public when publishing a bucket of open-source training data, Wiz said. It also included a disk backup of two former employees' workstations containing secrets, keys, passwords, and over 30,000 internal Teams messages. The repository, named " robust-models-transfer ," is no longer accessible. Prior to its takedown, it featured source code and machine learning models pertaining to a  2020 research paper   titled  "Do Adversarially Robust ImageNet Models Transfer Better?" "The exposure came as the result of an overly permissive  SAS token  – an Azure feature that allows users to share data in a manner that is both hard to track and hard to revoke," Wiz  said  in a report. The issue was reported to Microsoft on J

A new vulnerability disclosed in GitHub could have exposed thousands of repositories at risk of repojacking attacks, new findings show. The flaw "could allow an attacker to exploit a race condition within GitHub's repository creation and username renaming operations," Checkmarx security researcher Elad Rapoport  said  in a technical report shared with The Hacker News. "Successful exploitation of this vulnerability impacts the open-source community by enabling the hijacking of over 4,000 code packages in languages such as Go, PHP, and Swift, as well as GitHub actions." Following responsible disclosure on March 1, 2023, the Microsoft-owned code hosting platform has addressed the issue as of September 1, 2023. Repojacking , short for  repository hijacking , is a technique where a threat actor is able to bypass a security mechanism called popular repository namespace retirement and ultimately control of a repository. What the protection measure does is preven

Millions of software repositories on GitHub are likely vulnerable to an attack called RepoJacking , a new study has revealed. This includes repositories from organizations such as Google, Lyft, and several others, Massachusetts-based cloud-native security firm Aqua  said  in a Wednesday report. The supply chain vulnerability, also known as dependency repository hijacking, is a  class of attacks  that makes it possible to take over retired organization or user names and publish trojanized versions of repositories to run malicious code. "When a repository owner changes their username, a link is created between the old name and the new name for anyone who downloads dependencies from the old repository," researchers Ilay Goldman and Yakir Kadkoda said. "However, it is possible for anyone to create the old username and break this link." Alternatively, a similar scenario could arise when a repository ownership is transferred to another user and the original account

At least half of dozen GitHub accounts from fake researchers associated with a fraudulent cybersecurity company have been observed pushing malicious repositories on the code hosting service. All seven repositories, which are still available as of writing, claim to be a proof-of-concept (PoC) exploit for purported zero-day flaws in Discord, Google Chrome, and Microsoft Exchange Server. VulnCheck, which discovered the activity,  said , "the individuals creating these repositories have put significant effort into making them look legitimate by creating a network of accounts and Twitter profiles, pretending to be part of a non-existent company called High Sierra Cyber Security." The cybersecurity firm said it first came across the rogue repositories in early May when they were observed releasing similar PoC exploits for zero-day bugs in Signal and WhatsApp. The repositories hosting the two PoCs have since been taken down. Besides sharing some of the purported findings on Tw

The most precious asset in today's information age is the secret safeguarded under lock and key. Regrettably, maintaining secrets has become increasingly challenging, as highlighted by the  2023 State of Secrets Sprawl  report, the largest analysis of public GitHub activity.  The report shows a  67% year-over-year increase  in the number of secrets found, with 10 million hard-coded secrets detected in 2022 alone. This alarming surge in secrets sprawl highlights  the need for action  and underscores the importance of secure software development. Secrets sprawl refers to secrets appearing in plaintext in various sources, such as source code, build scripts, infrastructure as code, logs, etc. While secrets like API tokens and private keys securely connect the components of the modern software supply chain, their widespread distribution among developers, machines, applications, and infrastructure systems heightens the likelihood of leaks. Cybersecurity Incidents Highlight the Danger

GitHub has announced the general availability of a new security feature called  push protection , which aims to prevent developers from inadvertently leaking keys and other secrets in their code. The Microsoft-owned cloud-based repository hosting platform, which began  testing the feature  a year ago, said it's also extending push protection to all public repositories at no extra cost. The functionality is designed to work hand-in-hand with the existing  secret scanning feature , which scans repositories for known secret formats to prevent their fraudulent use and avert potentially serious consequences. "Push protection prevents secret leaks without compromising the developer experience by scanning for highly identifiable secrets before they are committed," GitHub  said  earlier this week. "When a secret is detected in code, developers are prompted directly in their IDE or command line interface with remediation guidance to ensure that the secret is never expo

The supply chain attack targeting 3CX was the result of a prior supply chain compromise associated with a different company, demonstrating a new level of sophistication with North Korean threat actors. Google-owned Mandiant, which is  tracking  the attack event under the moniker  UNC4736 ,  said  the incident marks the first time it has seen a "software supply chain attack lead to another software supply chain attack." The Matryoshka doll-style cascading attack against 3CX first came to light on March 29, 2023, when it  emerged  that Windows and macOS versions of its communication software were trojanized to deliver a C/C++-based data miner named ICONIC Stealer by means of a downloader, SUDDENICON, that used icon files hosted on GitHub to extract the server containing the stealer. "The malicious application next attempts to steal sensitive information from the victim user's web browser," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  said

The notorious North Korea-aligned state-sponsored actor known as the  Lazarus Group  has been attributed to a new campaign aimed at Linux users. The attacks are part of a persistent and long-running activity tracked under the name  Operation Dream Job , ESET said in a  new report  published today. The findings are crucial, not least because it marks the first publicly documented example of the adversary using Linux malware as part of this social engineering scheme. Operation Dream Job , also known as  DeathNote or NukeSped , refers to multiple attack waves wherein the group leverages fraudulent job offers as a lure to trick unsuspecting targets into downloading malware. It also  exhibits overlaps  with two other Lazarus clusters known as Operation In(ter)ception and Operation North Star. The attack chain discovered by ESET is no different in that it delivers a fake HSBC job offer as a decoy within a ZIP archive file that's then used to launch a Linux backdoor named SimplexTea
