The Rising Threat of Secrets Sprawl and the Need for Action

The Rising Threat of Secrets Sprawl and the Need for Action

May 23, 2023 Application Security
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.

GitHub Extends Push Protection to Prevent Accidental Leaks of Keys and Other Secrets

GitHub Extends Push Protection to Prevent Accidental Leaks of Keys and Other Secrets

May 11, 2023
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 ...
Product Walkthrough: How Reco Discovers Shadow AI in SaaS

Product Walkthrough: How Reco Discovers Shadow AI in SaaS

Jan 09, 2025AI Security / SaaS Security
As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...
N.K. Hackers Employ Matryoshka Doll-Style Cascading Supply Chain Attack on 3CX

N.K. Hackers Employ Matryoshka Doll-Style Cascading Supply Chain Attack on 3CX

Apr 21, 2023 Supply Chain Attack
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 (CI...

Lazarus Group Adds Linux Malware to Arsenal in Operation Dream Job

Lazarus Group Adds Linux Malware to Arsenal in Operation Dream Job

Apr 20, 2023 Linux / Cyber Attack
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 launc...
Are Source Code Leaks the New Threat Software vendors Should Care About?

Are Source Code Leaks the New Threat Software vendors Should Care About?

Apr 07, 2023 DevOps / Software
Less than a month ago, Twitter indirectly acknowledged that some of its source code had been leaked on the code-sharing platform GitHub by sending a copyright infringement notice to take down the incriminated repository. The latter is now inaccessible, but according to the media, it was accessible to the public for several months. A user going by the name FreeSpeechEnthousiast committed thousands of documents belonging to the social media platform over several months.  While there is no concrete evidence to support this hypothesis, the timing of the leak and the ironic username used by the perpetrator suggest that the leak was a deliberate act aimed at causing harm to the company. Although it is still too early to measure the impact of this leak on the health of Twitter, this incident should be an opportunity for all software vendors to ask a simple question:  what if this happened to us? Protecting sensitive information in the software industry is becoming increasingly cr...
GitHub Swiftly Replaces Exposed RSA SSH Key to Protect Git Operations

GitHub Swiftly Replaces Exposed RSA SSH Key to Protect Git Operations

Mar 24, 2023 Cloud Security / Programming
Cloud-based repository hosting service GitHub said it took the step of replacing its RSA SSH host key used to secure Git operations "out of an abundance of caution" after it was briefly exposed in a public repository. The activity, which was carried out at 05:00 UTC on March 24, 2023, is said to have been undertaken as a measure to prevent any bad actor from impersonating the service or eavesdropping on users' operations over SSH. "This key does not grant access to GitHub's infrastructure or customer data," Mike Hanley, chief security officer and SVP of engineering at GitHub,  said  in a post. "This change only impacts Git operations over SSH using RSA." The move does not impact Web traffic to GitHub.com and Git operations performed via HTTPS. No change is required for ECDSA or Ed25519 users. The Microsoft-owned company said there is no evidence that the exposed SSH private key was exploited by adversaries. It did not disclose how long the se...

Hackers Can Abuse Legitimate GitHub Codespaces Feature to Deliver Malware

Hackers Can Abuse Legitimate GitHub Codespaces Feature to Deliver Malware

Jan 17, 2023 Threat Response / Malware
New research has found that it is possible for threat actors to abuse a legitimate feature in GitHub Codespaces to deliver malware to victim systems. GitHub Codespaces  is a cloud-based configurable development environment that allows users to debug, maintain, and commit changes to a given codebase from a web browser or via an integration in Visual Studio Code. It also comes with a port forwarding feature that makes it possible to access a web application that's running on a particular port within the codespace directly from the browser on a local machine for testing and debugging purposes. "You can also forward a port manually, label forwarded ports, share forwarded ports with members of your organization, share forwarded ports publicly, and add forwarded ports to the codespace configuration," GitHub  explains  in its documentation. It's  important  to note here that any forwarded port that's made public will also permit any party with knowledge of the UR...
Hackers Using CAPTCHA Bypass Tactics in Freejacking Campaign on GitHub

Hackers Using CAPTCHA Bypass Tactics in Freejacking Campaign on GitHub

Jan 06, 2023 Cryptocurrency / GitHub
A South Africa-based threat actor known as Automated Libra has been observed employing CAPTCHA bypass techniques to create GitHub accounts in a programmatic fashion as part of a freejacking campaign dubbed PURPLEURCHIN. The group "primarily targets cloud platforms offering limited-time trials of cloud resources in order to perform their crypto mining operations," Palo Alto Networks Unit 42 researchers William Gamazo and Nathaniel Quist  said . PURPLEURCHIN first came to light in October 2022 when Sysdig  disclosed  that the adversary created as many as 30 GitHub accounts, 2,000 Heroku accounts, and 900 Buddy accounts to scale its operation. Now according to Unit 42, the cloud threat actor group created three to five GitHub accounts every minute at the height of its activity in November 2022, totally setting up over 130,000 bogus accounts across Heroku, Togglebox, and GitHub. More than 22,000 GitHub accounts are estimated to have been created between September and No...
Hackers Breach Okta's GitHub Repositories, Steal Source Code

Hackers Breach Okta's GitHub Repositories, Steal Source Code

Dec 22, 2022 Software Security / Data Breach
Okta, a company that provides identity and access management services, disclosed on Wednesday that some of its source code repositories were accessed in an unauthorized manner earlier this month. "There is no impact to any customers, including any HIPAA, FedRAMP, or DoD customers," the company  said  in a public statement. "No action is required by customers." The security event, which was  first reported  by Bleeping Computer, involved unidentified threat actors gaining access to the Okta Workforce Identity Cloud ( WIC ) code repositories hosted on GitHub. The access was subsequently abused to copy the source code. The cloud-based identity management platform noted that it was alerted to the incident by Microsoft-owned GitHub in early December 2022. It also emphasized that the breach did not result in unauthorized access to customer data or the Okta service. Upon discovering the lapse, Okta said it placed temporary restrictions on repository access and that i...

Dropbox Breach: Hackers Unauthorizedly Accessed 130 GitHub Source Code Repositories

Nov 02, 2022
File hosting service Dropbox on Tuesday disclosed that it was the victim of a phishing campaign that allowed unidentified threat actors to gain unauthorized access to 130 of its source code repositories on GitHub. "These repositories included our own copies of third-party libraries slightly modified for use by Dropbox, internal prototypes, and some tools and configuration files used by the security team," the company  revealed  in an advisory. The breach resulted in the access of some API keys used by Dropbox developers as well as "a few thousand names and email addresses belonging to Dropbox employees, current and past customers, sales leads, and vendors." It, however, stressed that the repositories did not contain source code related to its core apps or infrastructure. Dropbox, which offers cloud storage, data backup, and document signing services, among others, has over 17.37 million paying users and 700 million registered users as of  August 2022 . The di...
GitHub Repojacking Bug Could've Allowed Attackers to Takeover Other Users' Repositories

GitHub Repojacking Bug Could've Allowed Attackers to Takeover Other Users' Repositories

Oct 31, 2022
Cloud-based repository hosting service GitHub has addressed a high-severity security flaw that could have been exploited to create malicious repositories and mount supply chain attacks. The RepoJacking technique,  disclosed  by Checkmarx, entails a bypass of a protection mechanism called  popular repository namespace retirement , which aims to prevent developers from pulling unsafe repositories with the same name. The issue was addressed by the Microsoft-owned subsidiary on September 19, 2022 following responsible disclosure. RepoJacking  occurs  when a creator of a repository opts to change the username, potentially enabling a threat actor to claim the old username and publish a rogue repository with the same name in an attempt to trick users into downloading them. While Microsoft's countermeasure "retire[s] the namespace of any open source project that had more than 100 clones in the week leading up to the owner's account being renamed or deleted," Che...

Hackers Using Fake CircleCI Notifications to Hack GitHub Accounts

Hackers Using Fake CircleCI Notifications to Hack GitHub Accounts

Sep 23, 2022
GitHub has put out an advisory detailing what may be an ongoing phishing campaign targeting its users to steal credentials and two-factor authentication (2FA) codes by impersonating the CircleCI DevOps platform. The Microsoft-owned code hosting service said it learned of the attack on September 16, 2022, adding the campaign impacted "many victim organizations." The fraudulent messages claim to notify users that their CircleCI sessions have expired and that they should log in using GitHub credentials by clicking on a link. Another bogus email  revealed by CircleCI  prompts users to sign in to their GitHub accounts to accept the company's new Terms of Use and Privacy Policy by following the link embedded in the message. Regardless of the lure, doing so redirects the target to a lookalike GitHub login page designed to steal and exfiltrate the entered credentials as well as the Time-based One Time Password (TOTP) codes in real-time to the attacker, effectively allowing ...
