Cybersecurity Week in Review (03/05/24)

Millions of Malicious ‘Imageless’ Containers Planted on Docker Hub Over 5 Years

Cybersecurity researchers have discovered multiple campaigns targeting Docker Hub by planting millions of malicious “imageless” containers over the past five years, once again underscoring how open-source registries could pave the way for supply chain attacks.

What’s more, the documentation has no connection whatsoever to the container. Instead, it’s a web page that’s designed to lure users into visiting phishing or malware-hosting websites.

Of the 4.6 million imageless Docker Hub repositories uncovered, 2.81 million of them are said to have been used as landing pages to redirect unsuspecting users to fraudulent sites as part of three broad campaigns.

New R Programming Vulnerability Exposes Projects to Supply Chain Attacks

A security vulnerability has been discovered in the R programming language that could be exploited by a threat actor to create a malicious RDS (R Data Serialization) file such that it results in code execution when loaded and referenced.

The flaw, assigned the CVE identifier CVE-2024-27322 (CVSS score: 8.8), “involves the use of promise objects and lazy evaluation in R,” AI application security company HiddenLayer said in a report shared with The Hacker News.

RDS, like pickle in Python, is a format used to serialize and save the state of data structures or objects in R, an open-source programming language used in statistical computing, data visualization, and machine learning.

New Cuttlefish malware infects routers to monitor traffic for credentials

A new malware named ‘Cuttlefish’ has been spotted infecting enterprise-grade and small office/home office (SOHO) routers to monitor data that passes through them and steal authentication information.

Lumen Technologies’ Black Lotus Labs examined the new malware and reports that Cuttlefish creates a proxy or VPN tunnel on the compromised router to exfiltrate data discreetly while bypassing security measures that detect unusual sign-ins.

The malware can also perform DNS and HTTP hijacking within private IP spaces, interfering with internal communications and possibly introducing more payloads.

Avast fined nearly $15M for GDPR violations

The Office for Personal Data Protection (ÚOOÚ) in the Czech Republic has imposed a fine of approximately $14.8 million on Avast Software for General Data Protection Rules (GDPR) after investigating the company’s Czech branch, Jumpshot, INC.

According to ÚOOÚ, the company processed personal data from Avast antivirus software and browser extensions in 2019 without authorization.

The company transferred the data of 100 million of its users to Jumpshot, a company that marketed itself, among other things, as providing insights into online consumer behavior to third parties.

ÚOOÚ says that Avast misled users. While it claimed to use robust anonymization techniques, at least a portion of data subjects could be reidentified.

CISA Warns of Active Exploitation of Severe GitLab Password Reset Vulnerability

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical flaw impacting GitLab to its Known Exploited Vulnerabilities (KEV) catalog, owing to active exploitation in the wild.

Tracked as CVE-2023-7028 (CVSS score: 10.0), the maximum severity vulnerability could facilitate account takeover by sending password reset emails to an unverified email address.

GitLab, which disclosed details of the shortcoming earlier this January, said it was introduced as part of a code change in version 16.1.0 on May 1, 2023.

Successful exploitation of the issue can have serious consequences as it not only enables an adversary to take control of a GitLab user account, but also steal sensitive information, credentials, and even poison source code repositories with malicious code, leading to supply chain attacks.

CISA and Partners Release Fact Sheet on Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity

Today, CISA, in collaboration with U.S. and international partners, published a joint fact sheet, Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity. This fact sheet provides information and mitigations associated with cyber operations conducted by pro-Russia hacktivists who seek to compromise industrial control systems (ICS) and small-scale operational technology (OT) systems in North American and European critical infrastructure sectors, including Water and Wastewater Systems, Dams, Energy, and Food and Agriculture Sectors.

The pro-Russia hacktivist activity appears mostly limited to unsophisticated techniques that manipulate ICS equipment to create nuisance effects. However, investigations have identified that these actors are capable of techniques that pose physical threats against insecure and misconfigured OT environments.

CISA and partners encourage OT operators in critical infrastructure sectors to apply the recommendations listed in the fact sheet to defend against this activity. To learn more about secure by design principles and practices, visit CISA’s Secure by Design webpage. For more information and guidance on protection against the most common and impactful threats, tactics, techniques, and procedures, visit CISA’s Cross-Sector Cybersecurity Performance Goals.
