AWS Researchers Find an Interlock Server Laden With ToolsRansomware hackers exploited a flaw with a maximum vulnerability score in Cisco firewall management software weeks before the networking giant disclosed the vulnerability in early March. The group has focused extensively on critical infrastructure sectors in North America and Europe.

Cybersecurity researchers are calling attention to a new campaign where threat actors are abusing FortiGate Next-Generation Firewall (NGFW) appliances as entry points to breach victim networks.  The activity involves the exploitation of recently disclosed security vulnerabilities or weak credentials to extract configuration files containing service account credentials and network topology

Researchers warn that a newly identified open-source AI security testing platform called CyberStrikeAI was used by the same threat actor behind a recent campaign that breached hundreds of Fortinet FortiGate firewalls. [...]

In SEC filings, Fortinet and Palo Alto show shrinking product margins taking hold. PCs and datacenters aren't the only devices that need DRAM. The global memory shortage is roiling the cybersecurity market, with the cost of firewalls expected to balloon and hit both customers and vendors in the pocketbook in 2026, according to research analysts Wedbush.…

As exploitation activity against CVE-2025-55182 ramps up, researchers are finding some proof-of-concept exploits contain bypasses for web application firewall (WAF) rules.

Malicious actors have been observed exploiting a now-patched critical security flaw impacting Erlang/Open Telecom Platform (OTP) SSH as early as beginning of May 2025, with about 70% of detections originating from firewalls protecting operational technology (OT) networks

Akira Ransomware Exploited MFA-Protected SonicWall SSL VPNs, Say ResearchersSonicWall said it is probing a surge in attacks against its Gen 7 firewalls, running various firmware versions, which have SSL VPN enabled. Researchers said attackers may have been exploiting a zero-day vulnerability and that multiple victims have been infected with Akira ransomware.

Wiz researchers found an opportunistic threat actor has been targeting vulnerable edge devices, including Ivanti VPNs and Palo Alto firewalls.

Security researchers at Bishop Fox have published complete exploitation details for the CVE-2024-53704 vulnerability that allows bypassing the authentication mechanism in certain versions of the SonicOS SSLVPN application. [...]

Also: US Prosecutors Charge Suspected North Korean IT Worker CollaboratorsThis week, researchers spied Palo Alto firewall flaws, a North Korean IT worker conspiracy, ChatGPT as DDoS vector. Chinese hackers targeted a VPN maker, a fake PyPi package and a Russian threat actor shifted tactics. BreachForums admin faces prison and scammers used the release of Ross Ulbricht.

Actively Targeted Zero Day Patched; Warning Issued After Device Configurations LeakFortinet has released patches to fix a zero-day vulnerability being actively exploited by attackers. Separately, researchers are warning customers to review their infrastructure after attackers leaked configuration details - including firewall rules and plaintext VPN passwords - for 15,000 devices.

Ransomware 'not off the table,' Arctic Wolf threat hunter tells El Reg Miscreants running a "mass exploitation campaign" against Fortinet firewalls, which peaked in December, may be using an unpatched zero-day vulnerability to compromise the equipment, according to security researchers who say they've observed the intrusions.…

Firewall Vendor Warns Attackers Using Valid Credentials They Previously StoleAttackers wielding an emerging strain of ransomware called Helldown have been gaining a foothold in victims' networks by exploiting a previously unknown flaw in their Zyxel firewalls, security researchers warn. Zyxel has warned attackers may be using valid credentials they previously stole.

Amazing that these two bugs got into a production appliance, say researchers Palo Alto Networks (PAN) finally released a CVE identifier and patch for the zero-day exploit that caused such a fuss last week.…

Company Released a Hotfix to the Command Injection VulnerabilityFirewall appliance manufacturer Palo Alto Networks rushed out a hotfix Friday to a command injection vulnerability present in its custom operating system after security researchers spotted a campaign to exploit the zero-day starting in March, likely from a state-backed threat actor.
