GitLab has released security updates to address two critical vulnerabilities, including one that could be exploited to take over accounts without requiring any user interaction. Tracked as  CVE-2023-7028 , the flaw has been awarded the maximum severity of 10.0 on the CVSS scoring system and could facilitate account takeover by sending password reset emails to an unverified email address. The DevSecOps platform said the vulnerability is the result of a bug in the email verification process, which allowed users to reset their password through a secondary email address. It affects all self-managed instances of GitLab Community Edition (CE) and Enterprise Edition (EE) using the below versions - 16.1 prior to 16.1.6 16.2 prior to 16.2.9 16.3 prior to 16.3.7 16.4 prior to 16.4.5 16.5 prior to 16.5.6 16.6 prior to 16.6.4 16.7 prior to 16.7.2 GitLab said it addressed the issue in GitLab versions 16.5.6, 16.6.4, and 16.7.2, in addition to backporting the fix to versions 16.1....

Cybersecurity researchers have identified a new attack that exploits misconfigurations in Apache Hadoop and Flink to deploy cryptocurrency miners within targeted environments. "This attack is particularly intriguing due to the attacker's use of packers and rootkits to conceal the malware," Aqua security researchers Nitzan Yaakov and Assaf Morag  said  in an analysis published earlier this week. "The malware deletes contents of specific directories and modifies system configurations to evade detection." The infection chain targeting Hadoop leverages a misconfiguration in the YARN's (Yet Another Resource Negotiator)  ResourceManager , which is responsible for tracking resources in a cluster and scheduling applications. Specifically, the misconfiguration can be exploited by an unauthenticated, remote threat actor to execute arbitrary code by means of a crafted HTTP request, subject to the privileges of the user on the node where the code is executed. The ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a critical security vulnerability impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The issue, tracked as  CVE-2023-29357  (CVSS score: 9.8), is a privilege escalation flaw that could be exploited by an attacker to gain administrator privileges. Microsoft  released patches  for the bug as part of its June 2023 Patch Tuesday updates. "An attacker who has gained access to spoofed JWT authentication tokens can use them to execute a network attack which bypasses authentication and allows them to gain access to the privileges of an authenticated user," Redmond said. "The attacker needs no privileges nor does the user need to perform any action." Security researcher Nguyễn Tiến Giang (Jang) of StarLabs SG  demonstrated an exploit  for the flaw at the Pwn2Own Vancouver hacking contest last ye...

The ubiquity of GitHub in information technology (IT) environments has made it a lucrative choice for threat actors to host and deliver malicious payloads and act as  dead drop resolvers , command-and-control, and data exfiltration points. "Using GitHub services for malicious infrastructure allows adversaries to blend in with legitimate network traffic, often bypassing traditional security defenses and making upstream infrastructure tracking and actor attribution more difficult," Recorded Future  said  in a report shared with The Hacker News. The cybersecurity firm described the approach as "living-off-trusted-sites" (LOTS), a spin on the living-off-the-land (LotL) techniques often adopted by threat actors to conceal rogue activity and fly under the radar. Prominent among the methods by which GitHub is  abused   relates  to  payload   delivery , with some actors leveraging its features for command-and-control (C2) obfuscation. Last month, Reve...

Cybersecurity researchers have  developed  a proof-of-concept (PoC) code that exploits a  recently disclosed critical flaw  in the Apache OfBiz open-source Enterprise Resource Planning (ERP) system to execute a memory-resident payload. The vulnerability in question is  CVE-2023-51467  (CVSS score: 9.8), a bypass for another severe shortcoming in the same software ( CVE-2023-49070 , CVSS score: 9.8) that could be weaponized to circumvent authentication and remotely execute arbitrary code. While it was fixed in  Apache OFbiz version 18.12.11  released last month, threat actors have been observed attempting to exploit the flaw, targeting vulnerable instances. The latest findings from VulnCheck show that CVE-2023-51467 can be exploited to execute a payload directly from memory, leaving little to no traces of malicious activity. Security flaws disclosed in Apache OFBiz (e.g.,  CVE-2020-9496 ) have been  exploited  by threat actors ...

A new Python-based hacking tool called  FBot  has been uncovered targeting web servers, cloud services, content management systems (CMS), and SaaS platforms such as Amazon Web Services (AWS), Microsoft 365, PayPal, Sendgrid, and Twilio. "Key features include credential harvesting for spamming attacks, AWS account hijacking tools, and functions to enable attacks against PayPal and various SaaS accounts," SentinelOne security researcher Alex Delamotte  said  in a report shared with The Hacker News. FBot is the latest addition to the list of cloud hacking tools like  AlienFox, GreenBot  (aka Maintance),  Legion , and  Predator , the latter four of which share code-level overlaps with AndroxGh0st. SentinelOne described FBot as "related but distinct from these families," owing to the fact that it does not reference any source code from AndroxGh0st, although it exhibits similarities with Legion, which first came to light last year. The end goal of...

Generative AI will enable anyone to launch sophisticated phishing attacks that only Next-generation MFA devices can stop The least surprising headline from 2023 is that ransomware again set new records for a number of incidents and the damage inflicted. We saw new headlines every week, which included a who's-who of big-name organizations. If MGM, Johnson Controls, Chlorox, Hanes Brands, Caesars Palace, and so many others cannot stop the attacks, how will anyone else? Phishing-driven ransomware is the cyber threat that looms larger and more dangerous than all others. CISA and Cisco report that 90% of data breaches are the result of phishing attacks and monetary losses that exceed $10 billion in total. A report from Splunk revealed that 96 percent of companies fell victim to at least one phishing attack in the last 12 months and 83 percent suffered two or more. Protect your organization from phishing and ransomware by learning about the benefits of Next-Generation MFA. Download th...

Cybersecurity researchers have identified an updated version of a macOS information stealer called  Atomic  (or AMOS), indicating that the threat actors behind the malware are actively enhancing its capabilities. "It looks like Atomic Stealer was updated around mid to late December 2023, where its developers introduced payload encryption in an effort to bypass detection rules," Malwarebytes' Jérôme Segura  said  in a Wednesday report. Atomic Stealer  first emerged  in April 2023 for a monthly subscription of $1,000. It's capable of harvesting sensitive information from a compromised host, including Keychain passwords, session cookies, files, crypto wallets, system metadata, and the machine's password via a fake prompt. Over the past several months, the malware has been observed propagated via  malvertising  and  compromised sites  under the guise of legitimate software and web browser updates. Malwarebytes' latest analysis shows th...

The compromise of Mandiant's X (formerly Twitter) account last week was likely the result of a "brute-force password attack," attributing the hack to a drainer-as-a-service (DaaS) group. "Normally, [two-factor authentication] would have mitigated this, but due to some team transitions and a change in X's 2FA policy , we were not adequately protected," the threat intelligence firm  said  in a post shared on X. The attack, which took place on January 3, 2023,  enabled  the threat actor to take control of the company's X account and distribute links to a phishing page hosting a cryptocurrency drainer tracked as CLINKSINK. Drainers refer to malicious scripts and smart contracts that facilitate the theft of digital assets from the victim's wallets after they are tricked into approving the transactions. According to the Google-owned subsidiary, multiple threat actors are believed to have leveraged CLINKSINK since December 2023 to siphon funds and tok...

A pair of zero-day flaws identified in Ivanti Connect Secure (ICS) and Policy Secure have been chained by suspected China-linked nation-state actors to breach less than 10 customers. Cybersecurity firm Volexity, which  identified  the activity on the network of one of its customers in the second week of December 2023, attributed it to a hacking group it tracks under the name  UTA0178 . There is evidence to suggest that the VPN appliance may have been compromised as early as December 3, 2023. The two vulnerabilities that have been exploited in the wild to achieve unauthenticated command execution on the ICS device are as follows - CVE-2023-46805  (CVSS score: 8.2) - An authentication bypass vulnerability in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows a remote attacker to access restricted resources by bypassing control checks. CVE-2024-21887  (CVSS score: 9.1) - A command injection vulnerability in web components...

Cisco has released software updates to address a critical security flaw impacting Unity Connection that could permit an adversary to execute arbitrary commands on the underlying system. Tracked as  CVE-2024-20272  (CVSS score: 7.3), the vulnerability is an arbitrary file upload bug residing in the web-based management interface and is the result of a lack of authentication in a specific API and improper validation of user-supplied data. "An attacker could exploit this vulnerability by uploading arbitrary files to an affected system," Cisco  said  in an advisory released Wednesday. "A successful exploit could allow the attacker to store malicious files on the system, execute arbitrary commands on the operating system, and elevate privileges to root." The flaw impacts the following versions of Cisco Unity Connection. Version 15 is not vulnerable. 12.5 and earlier (Fixed in version 12.5.1.19017-4) 14 (Fixed in version 14.0.1.14006-5) Security researcher Maxim ...

A new Mirai-based botnet called  NoaBot  is being used by threat actors as part of a crypto mining campaign since the beginning of 2023. "The capabilities of the new botnet, NoaBot, include a wormable self-spreader and an SSH key backdoor to download and execute additional binaries or spread itself to new victims," Akamai security researcher Stiv Kupchik said in a report shared with The Hacker News. Mirai , which had its source code leaked in 2016, has been the progenitor of a number of botnets, the most recent being  InfectedSlurs , which is capable of mounting distributed denial-of-service (DDoS) attacks. There are indications that NoaBot could be linked to another botnet campaign involving a Rust-based malware family known as  P2PInfect , which recently received an update to target routers and IoT devices. This is based on the fact that threat actors have also experimented with dropping P2PInfect in place of NoaBot in recent attacks targeting SSH servers, i...
