Axios npm package compromised in supply chain attack on July 23, 2026
On July 23, 2026, the Axios npm package, a widely used JavaScript HTTP client, was compromised in a sophisticated supply chain attack. The attackers hijacked a maintainer account and injected a malicious dependency, `plain-crypto-js`, into versions `axios@1.14.1` and `axios@0.30.4`. This malicious dependency was designed to download multi-stage payloads, including a remote access trojan, onto developer machines and CI/CD pipelines globally. The compromise was detected and the malicious packages were removed from npm within approximately three hours. The attack was characterized by its operational sophistication, bypassing standard security controls like MFA through a targeted social engineering campaign against the maintainer. The malicious code was capable of breaching major operating systems including Windows, macOS, and Linux. CISA issued an alert providing guidance for detection and remediation, urging organizations to monitor code repositories, CI/CD pipelines, and developer machines, and to rotate credentials that may have been exposed. Google Threat Intelligence Group publicly attributed the compromise to UNC1069, a North Korea-nexus, financially motivated threat actor. The incident highlights the significant risks associated with software supply chain attacks and the importance of robust security measures for open-source dependencies.

Dropbox Suffers Data Breach in Phishing Attack Targeting GitHub Account
Dropbox, a cloud storage company, experienced a data breach when its GitHub account was compromised on October 13. The attackers gained access to 130 code repositories containing sensitive data, including API keys used by Dropbox developers. The incident was a result of a successful email phishing campaign that targeted Dropbox employees, impersonating CircleCI, a continuous integration and delivery platform. The phishing emails directed victims to a fake login page where they were prompted to enter their GitHub credentials and a One-Time Password (OTP) from their hardware authentication key. Dropbox was notified of the potential breach by GitHub on October 14. While the attackers accessed some credentials and API keys, Dropbox stated that customer accounts, passwords, or payment information were not compromised, nor were its core apps or infrastructure. The data accessed also included the names and email addresses of a few thousand Dropbox employees, current and past customers, sales leads, and vendors. In response, Dropbox is enhancing its security by implementing WebAuthn and hardware tokens or biometrics.

DoorDash Confirms Data Breach After Social Engineering Attack
DoorDash, the popular food delivery platform, publicly acknowledged a cybersecurity incident that compromised the personal information of an undisclosed number of users. The breach, which occurred on October 25, was a result of a social engineering attack targeting a company employee. This allowed an unauthorized third party to gain access to DoorDash's internal systems. The compromised data varied by individual but potentially included first and last names, phone numbers, email addresses, and physical addresses of customers, Dashers (delivery drivers), and merchants across the United States, Canada, Australia, and New Zealand. DoorDash emphasized that no sensitive financial information, such as Social Security numbers, government-issued IDs, driver's license details, bank information, or payment card data, was accessed. The company's security team identified and shut down the unauthorized access shortly after its detection, launched an internal investigation, and notified law enforcement. DoorDash has also implemented multiple security enhancements, including upgraded security systems and additional employee training programs focused on social engineering awareness. While the company has stated there is no indication the data has been misused for fraud or identity theft, affected users are advised to be cautious of unsolicited communications requesting personal information. This incident marks DoorDash's third known cybersecurity incident in six years, highlighting the persistent threat of social engineering attacks.

Singapore Land Authority Data Breach Exposes 70,000 Records via IBM Testing Environment
Singapore Land Authority data breach exposes 70,000 records after IBM testing environment compromised SINGAPORE, July 3 — Personal data belonging to about 70,000 individuals has been compromised in a cybersecurity incident involving the Singapore Land Authority (SLA) and a cloud environment managed by IBM. SLA said the breach stemmed from unauthorised access to a dataset created for vendor development and systems integration testing, CNA reported. IBM oversees the testing environment for the Singapore Titles Automated Registration System (STARS) and eLodgment System (ELS), which are used to submit property transfer and caveat documents. Preliminary checks showed the dataset, first created in 1998 and updated periodically, was intended to contain only mock and anonymised records. It was later discovered to include real information such as names, NRIC numbers and past property addresses of around 70,000 people. SLA stressed that the affected environment is separate from its live operational systems, adding that property ownership and lodgment records in STARS and ELS remain secure. IBM has revoked access to the compromised system to prevent further unauthorised entry. As a precaution, SLA has begun notifying affected individuals and advising them on assistance measures. The authority said it is working with IBM, the Government Technology Agency of Singapore and the Cyber Security Agency of Singapore to investigate the incident and implement remedial steps. According to CNA, a police report has been lodged and the Personal Data Protection Commission has been notified. SLA has not yet disclosed when the breach occurred or how many affected individuals have been contacted.

IBM was appointed to support and maintain SLA’s Singapore Titles Automated Registration System (Stars) and eLodgment System (ELS), which underpin property title registration and the lodgement of property documents in the city-state. As part of that work, the supplier managed the development and systems integration testing environment for the two systems. In a statement on 3 July 2026, SLA said it had been informed by IBM of the incident, with preliminary investigations indicating that a dataset created solely for development and testing purposes had been accessed without authorisation. The dataset, created in 1998 and updated periodically over the years, was meant to contain only mock and anonymised testing data based on property ownership and lodgement records. However, SLA said it has since uncovered that the dataset also contained the names, National Registration Identity Card (NRIC) numbers and property addresses of the affected individuals at the time. “This information should have been anonymised but was not,” the agency said, adding that investigations are ongoing to determine how this occurred. SLA noted that the affected environment is “distinct and separate” from its operational systems, with no connection to, or compromise of, the live systems that run Stars, ELS or any other SLA systems. Property ownership and lodgement records remain secure and unaffected, it added. IBM has revoked access associated with the affected environment to prevent further unauthorised access, while SLA has identified the individuals whose information was contained in the dataset, and has begun notifying them and advising them on how to seek further information and assistance.

Philippine bank BDO is shoring up its cyber security capabilities to protect its data and systems as it moves more services to the cloud and expands its physical presence into remote areas of the archipelago. The agency is working with IBM, the Government Technology Agency and the Cyber Security Agency of Singapore (CSA) to establish the full facts and ensure remedial measures are taken. It has also lodged a police report and notified the Personal Data Protection Commission, and urged the public to remain vigilant against phishing emails, websites, text messages and phone calls from parties claiming to represent government agencies or other organisations. “We apologise for the concern and inconvenience this incident may cause,” the SLA said. The incident underscores the long-standing risk of real personal data finding its way into development and test environments , which are typically less closely guarded than production systems – a risk that is compounded when those environments are operated by third parties. It is also the latest in a series of supply chain security incidents in Singapore in recent years. In April 2025, Toppan Next Tech, a printing supplier for DBS Bank and the Singapore branch of Bank of China, was hit by a ransomware attack that saw customer data stolen by the threat actor . Some 8,200 DBS customers – mostly holders of DBS Vickers trading accounts and Cashline loans – and around 3,000 Bank of China customers were potentially affected. A year earlier, in August 2024, a hacker who gained unauthorised access to Mobile Guardian , a mobile device management platform then deployed across Singapore’s schools, remotely wiped the iPads and Chromebooks of about 13,000 students from 26 secondary schools. The Ministry of Education subsequently removed the software from all student devices and terminated its contract with the supplier.
