Are millions of enterprise users, who rely on the next-generation firewalls for protection, actually protected from hackers? Probably Not. Just less than a month after an unauthorized backdoor found in Juniper Networks firewalls, an anonymous security researcher has discovered highly suspicious code in FortiOS firewalls from enterprise security vendor Fortinet. According to the leaked information, FortiOS operating system, deployed on Fortinet's FortiGate firewall networking equipment, includes an SSH backdoor that can be used to access its firewall equipment. Anyone can Access FortiOS SSH Backdoor Anyone with " Fortimanager_Access " username and a hashed version of the " FGTAbc11*xy+Qqz27 " password string, which is hard coded into the firewall, can login into Fortinet's FortiGate firewall networking equipment. However, according to the company's product details, this SSH user is created for challenge-and-response authenti...

Threat hunters are calling attention to a new campaign that has targeted Fortinet FortiGate firewall devices with management interfaces exposed on the public internet. "The campaign involved unauthorized administrative logins on management interfaces of firewalls, creation of new accounts, SSL VPN authentication through those accounts, and various other configuration changes," cybersecurity firm Arctic Wolf said in an analysis published last week. The malicious activity is believed to have commenced in mid-November 2024, with unknown threat actors gaining unauthorized access to management interfaces on affected firewalls to alter configurations and extract credentials using DCSync . The exact initial access vector is currently not known, although it has been assessed with "high confidence" that it's likely driven by the exploitation of a zero-day vulnerability given the "compressed timeline across affected organizations as well as firmware versions af...

A now-patched security flaw in Veeam Backup & Replication software is being exploited by a nascent ransomware operation known as EstateRansomware. Singapore-headquartered Group-IB, which discovered the threat actor in early April 2024, said the modus operandi involved the exploitation of CVE-2023-27532 (CVSS score: 7.5) to carry out the malicious activities. Initial access to the target environment is said to have been facilitated by means of a Fortinet FortiGate firewall SSL VPN appliance using a dormant account. "The threat actor pivoted laterally from the FortiGate Firewall through the SSL VPN service to access the failover server," security researcher Yeo Zi Wei said in an analysis published today. "Before the ransomware attack, there were VPN brute-force attempts noted in April 2024 using a dormant account identified as 'Acc1.' Several days later, a successful VPN login using 'Acc1' was traced back to the remote IP address 149.28.106[.]25...

The zero-day exploitation of a now-patched medium-severity security flaw in the Fortinet  FortiOS  operating system has been linked to a suspected Chinese hacking group. American cybersecurity company Mandiant, which made the attribution, said the activity cluster is part of a broader campaign designed to deploy backdoors onto Fortinet and VMware solutions and maintain persistent access to victim environments. The Google-owned threat intelligence and incident response firm is tracking the malicious operation under its uncategorized moniker UNC3886 , describing it as a China-nexus threat actor. "UNC3886 is an advanced cyber espionage group with unique capabilities in how they operate on-network as well as the tools they utilize in their campaigns," Mandiant researchers  said  in a technical analysis. "UNC3886 has been observed targeting firewall and virtualization technologies which lack EDR support. Their ability to manipulate firewall firmware and exploit a zer...

2021 was a year peppered by cyberattacks, with numerous data breaches happening. Not only that, but ransomware has also become a prominent player in the hackers' world. Now, more than ever, it's important for enterprises to step up cybersecurity measures. They can do this through several pieces of technology, such as an open-source security platform like Wazuh .  Wazuh is a free and open source security platform that unifies XDR and SIEM capabilities, which not only enables companies to detect sophisticated threats, but can also help immensely in preventing data breaches and leaks from happening. As a result, it can save businesses from costly fixes that can ultimately end in their closure. It is also possible to integrate Wazuh with a number of external services and tools. Some of them are VirusTotal, YARA, Amazon Macie, Slack, and Fortigate Firewall. Consequently, companies can improve their security against hackers from penetrating their networks. What's great abou...

Welcome to your weekly cybersecurity scoop! Ever thought about how the same AI meant to protect our hospitals could also compromise them? This week, we're breaking down the sophisticated world of AI-driven threats, key updates in regulations, and some urgent vulnerabilities in healthcare tech that need our attention. As we unpack these complex topics, we'll equip you with sharp insights to navigate these turbulent waters. Curious about the solutions? They're smarter and more unexpected than you might think. Let's dive in. ⚡ Threat of the Week Juniper Networks Routers Targeted by J-magic — A new campaign targeted enterprise-grade Juniper Networks routers between mid-2023 and mid-2024 to infect them with a backdoor dubbed J-magic when certain precise conditions. The malware is a variant of a nearly 25-year-old, publicly available backdoor referred to as cd00r, and is designed to establish a reverse shell to an attacker-controlled IP address and port. Semiconductor, energy, manuf...

With breaches making the headlines on an almost weekly basis, the cybersecurity challenges we face are becoming visible not only to large enterprises, who have built security capabilities over the years, but also to small to medium businesses and the broader public. While this is creating greater awareness among smaller businesses of the need to improve their security posture, SMBs are often left facing a gap in the market, unable to find security tooling that is both easy for them to use and which they can afford. When we consider the needs of SMBs, we need to focus both on the development of threat intelligence, which is necessary to understand and identify the threats being faced, as well  as the tools used to provide protection . NTTSH has built a pedigree of over 20 years' experience in the research and curation of threat intelligence as well as the development of capabilities and products which leverage its threat intelligence to protect customers. After many years of focus...

Details have emerged about a new unpatched security vulnerability in Fortinet's web application firewall (WAF) appliances that could be abused by a remote, authenticated attacker to execute malicious commands on the system. "An OS command injection vulnerability in FortiWeb's management interface (version 6.3.11 and prior) can allow a remote, authenticated attacker to execute arbitrary commands on the system, via the SAML server configuration page," cybersecurity firm Rapid7  said  in an advisory published Tuesday. "This vulnerability appears to be related to  CVE-2021-22123 , which was addressed in  FG-IR-20-120 ." Rapid7 said it discovered and reported the issue in June 2021. Fortinet is expected to release a patch at the end of August with version Fortiweb 6.4.1. The command injection flaw is yet to be assigned a CVE identifier, but it has a severity rating of 8.7 on the CVSS scoring system. Successful exploitation of the vulnerability can allow auth...
