Print management software provider PaperCut said that it has "evidence to suggest that unpatched servers are being exploited in the wild," citing two vulnerability reports from cybersecurity company Trend Micro. "PaperCut has conducted analysis on all customer reports, and the earliest signature of suspicious activity on a customer server potentially linked to this vulnerability is 14th April 01:29 AEST / 13th April 15:29 UTC," it further  added . The update comes as the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a critical improper access control flaw ( CVE-2023-27350 , CVSS score: 9.8) in PaperCut MF and NG to the Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. Cybersecurity company Huntress, which found about 1,800 publicly exposed PaperCut servers, said it observed PowerShell commands being spawned from PaperCut software to install remote management and maintenance (RMM) software like Atera an...

Lazarus, the prolific North Korean hacking group behind the cascading  supply chain attack targeting 3CX , also breached two critical infrastructure organizations in the power and energy sector and two other businesses involved in financial trading using the trojanized X_TRADER application. The new findings, which come courtesy of  Symantec's Threat Hunter Team , confirm earlier suspicions that the X_TRADER application compromise affected more organizations than 3CX. The names of the organizations were not revealed. Eric Chien, director of security response at Broadcom-owned Symantec, told The Hacker News in a statement that the attacks took place between September 2022 and November 2022. "The impact from these infections is unknown at this time – more investigation is required and is on-going," Chien said, adding it's possible that there's "likely more to this story and possibly even other packages that are trojanized." The development comes as Ma...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added three security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The  three vulnerabilities  are as follows - CVE-2023-28432  (CVSS score - 7.5) - MinIO Information Disclosure Vulnerability  CVE-2023-27350  (CVSS score - 9.8) - PaperCut MF/NG Improper Access Control Vulnerability CVE-2023-2136  (CVSS score - TBD) - Google Chrome Skia Integer Overflow Vulnerability "In a cluster deployment, MinIO returns all environment variables, including MINIO_SECRET_KEY and MINIO_ROOT_PASSWORD, resulting in information disclosure," MinIO maintainers  said  in an advisory published on March 21, 2023. Data gathered by GreyNoise shows that as many as  18 unique malicious IP addresses  from the U.S., the Netherlands, France, Japan, and Finland have  attempted to exploit  the flaw over the past 30 days. ...

A large-scale attack campaign discovered in the wild has been exploiting Kubernetes (K8s) Role-Based Access Control ( RBAC ) to create backdoors and run cryptocurrency miners. "The attackers also deployed DaemonSets to take over and hijack resources of the K8s clusters they attack," cloud security firm Aqua said in a report shared with The Hacker News. The Israeli company, which dubbed the attack  RBAC Buster , said it found 60 exposed K8s clusters that have been exploited by the threat actor behind this campaign. The attack chain commenced with the attacker gaining initial access via a misconfigured API server, followed by checking for evidence of competing miner malware on the compromised server, and then using RBAC to set up persistence. "The attacker created a new ClusterRole with near admin-level privileges," the company said. "Next, the attacker created a 'ServiceAccount', 'kube-controller' in the 'kube-system' namespace. Las...

Cybersecurity researchers have disclosed details of a now-patched zero-day flaw in Google Cloud Platform (GCP) that could have enabled threat actors to conceal an unremovable, malicious application inside a victim's Google account. Dubbed GhostToken by Israeli cybersecurity startup Astrix Security, the shortcoming impacts all Google accounts, including enterprise-focused Workspace accounts. It was discovered and reported to Google on June 19, 2022. The company deployed a global-patch more than nine months later on April 7, 2023. "The vulnerability [...] allows attackers to gain permanent and unremovable access to a victim's Google account by converting an already authorized third-party application into a malicious trojan app, leaving the victim's personal data exposed forever," Astrix  said  in a report. In a nutshell, the flaw makes it possible for an attacker to hide their malicious app from a victim's Google account  application management page , the...

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...

Cisco and VMware have released security updates to address critical security flaws in their products that could be exploited by malicious actors to execute arbitrary code on affected systems. The most severe of the vulnerabilities is a command injection flaw  in Cisco Industrial Network Director  (CVE-2023-20036, CVSS score: 9.9), which resides in the web UI component and arises as a result of improper input validation when  uploading a Device Pack . "A successful exploit could allow the attacker to execute arbitrary commands as NT AUTHORITY\SYSTEM on the underlying operating system of an affected device," Cisco  said  in an advisory released on April 19, 2023. The networking equipment major also resolved a medium-severity file permissions vulnerability in the same product (CVE-2023-20039, CVSS score: 5.5) that an authenticated, local attacker could abuse to view sensitive information. Patches have been made available in  version 1.11.3 , with Cisco c...

A chain of two critical flaws has been disclosed in Alibaba Cloud's ApsaraDB RDS for PostgreSQL and AnalyticDB for PostgreSQL that could be exploited to breach tenant isolation protections and access sensitive data belonging to other customers. "The vulnerabilities potentially allowed unauthorized access to Alibaba Cloud customers' PostgreSQL databases and the ability to perform a supply chain attack on both Alibaba database services, leading to an RCE on Alibaba database services," cloud security firm Wiz  said  in a new report shared with The Hacker News. The  issues , dubbed  BrokenSesame , were reported to Alibaba Cloud in December 2022, following mitigations were deployed by the company on April 12, 2023. There is no evidence to suggest that the weaknesses were exploited in the wild. In a nutshell, the vulnerabilities – a privilege escalation flaw in AnalyticDB and a remote code execution bug in ApsaraDB RDS – made it possible to elevate privileges to root ...
