U.S. Seizes NightmareStresser Domains Linked to Hundreds of Thousands of DDoS Attacks

The U.S. Department of Justice (DoJ) on Tuesday announced the court-authorized seizure of internet domains associated with a distributed denial-of-service (DDoS)-for-hire service known as NightmareStresser. The domains in question are: nightmare-stresser[.]com and nightmarestresser[.]org. Visitors to the site are now greeted by a seizure banner that states - "This domain has been seized by the Federal Bureau of Investigation in accordance with a seizure warrant pursuant to 18 U.S.C. §§ 981(a)(1)(A) and (b), 982(b)(1), and 1030(i) (1)(A); and 21 U.S.C. § 853 issued by the United States District Court for the District of Alaska as part of a joint international law enforcement operation and action by: United States Attorney's Office for the District of Alaska, Federal Bureau of Investigation (FBI) Anchorage Field Office, [and] Royal Canadian Mounted Police (RCMP)." These so-called booter services are usually advertised as stress testing utilities but have been used ...

Attackers Exploit Issabel Framework Flaw Enabling Unauthenticated OS Command Execution

A critical security flaw in Issabel Framework , a web-based framework for the open-source unified communications PBX software, has come under active exploitation. The vulnerability in question is CVE-2026-89026 (CVSS v3.1 score: 9.8/CVSS v4.0 score: 9.3), which can allow an unauthenticated remote attacker to execute arbitrary operating system (OS) commands by taking advantage of a hard-coded JSON Web Token (JWT) signing key. The Issabel Framework "contains a hard-coded HS256 JWT signing key in the pbxapi index.php file that is identical across every installation, allowing unauthenticated remote attackers to forge valid bearer tokens," VulnCheck said in an alert. "Attackers can use the forged token to call the manager '/pbxapi/manager/originate' endpoint with the System application parameter, causing Asterisk to execute arbitrary OS commands as the Asterisk user." A patch for the vulnerability was pushed on August 1, 2026, and plugs the flaw by r...

Three Threat Groups Target Russian Enterprises With Backdoors, Ransomware, and Wipers

Enterprises in Russia have emerged as the target of three threat activity clusters tracked as NightEagle , Hacking Cat , and Toy Ghouls , according to multiple reports from Kaspersky. The cybersecurity vendor said it has identified attacks mounted by NightEagle (aka APT-Q-95), a threat actor known to be active since at least 2023, that involve new techniques for persistence and lateral movement. "In most incidents, the attackers used compromised valid credentials to gain access to corporate VPNs," Kaspersky said in an analysis published today. "VPN connections originated from IP addresses in the Russian segment linked to Cloudflare WARP tunnels, as well as from IP addresses associated with European virtual infrastructure providers." The attacks, as highlighted in July 2025, involve the deployment of GhostContainer , a known modular backdoor that grants the operators complete access to a victim's Microsoft Exchange Server, as well as run arbitrary code, ...

One Extension Could Hijack AI Assistants Across Chrome, Comet, Edge, Opera Neon and Claude

Security researchers at Forever Security have shown that one ordinary browser extension could take control of the AI assistants built into five Chromium-based products: Gemini Live in Chrome, Perplexity Comet, Microsoft Edge, Opera Neon and the Claude in Chrome extension. Once the extension was installed, it could access each product's built-in AI with a single click. On Comet, Edge, Opera Neon, and Claude in Chrome, it could drive the AI agent to act on behalf of the attacker; on Chrome and Comet, it could read files from the user's computer, and on Chrome, it could also switch on the camera and microphone. The findings are researcher demonstrations, not attacks seen in the wild, and each requires the attacker's extension to be already running in the victim's browser. These products all work the same way. The AI has a "body" inside the browser that can see the screen, open files, use the camera, and take actions, and a "brain" that runs on th...

Attacker Hijacks AI Coding Assistant Session, Spreads Shai-Hulud Across About 100 Repositories

Mandiant says an attacker hijacked an active AI coding-assistant session at an unnamed software-as-a-service provider and later spread  Shai-Hulud  across about 100 internal code repositories. Before the repository spread, the assistant recommended software that the attacker had poisoned, and the recommendation was accepted. The worm stole repository secrets and source code for the company's products. The case appears in  Mandiant's September 2026 report . The public case study does not say when the intrusion happened or how the attacker took over the active coding-assistant session. How the Attack Unfolded After the recommendation was accepted, the attacker used the developer's active session to install an infostealer through a poisoned PyPI package. The attacker also stole GitHub OAuth tokens. The attacker then deployed the self-spreading Shai-Hulud worm across approximately 100 internal code repositories. The attacker also poisoned a package in the company...

Parallels Desktop Flaw Lets Non-Admin Mac Users Gain Root, but Intel Macs Can't Install Fix

Parallels Desktop for Mac has a flaw that lets an ordinary local account run code as root, the highest level of access on a Mac, software company JFrog said this week. The attack needs code already running on the machine as a normal user, so it does not work over the network. JFrog says the fix is in Parallels Desktop 27, a version that Intel Macs cannot install. Yuval Moravchick, who leads JFrog's vulnerability research team,  published the finding  on Tuesday and calls it ParaShells. The flaw is tracked as  CVE-2026-90894 , an identifier JFrog assigned itself, and JFrog rates it 7.8 out of 10. Parallels Desktop runs Windows and Linux inside virtual machines on a Mac. It installs a background service called prl_disp_service that runs as root, because its work includes setting up host networking and unpacking virtual machine packages. The flaw is on the Mac side of the product, so the machine at risk is the Mac itself rather than the virtual machines on...

N0va Phishkit Targets US and EU Businesses: A New Challenge for Identity Security

N0va is targeting organizations across North America and Europe with phishing campaigns that impersonate trusted services and abuse legitimate authentication flows. Successful attacks can give threat actors access to valid accounts without relying on obvious malware activity. From there, a single compromised identity can open the door to sensitive data, business systems, and additional cloud resources. The longer that access goes unnoticed, the greater the potential for wider compromise, operational disruption, and financial loss. N0va Is Reaching Organizations Across High-Risk Sectors N0va activity has been observed across organizations in government, technology, consulting, healthcare, and other sectors in North America and Europe. Its use of trusted business platforms and cloud services makes the campaign relevant across a wide range of organizations. N0va phishing campaign attack details Related activity can be traced in ANY.RUN’s Threat Intelligence Lookup using a chara...

Google Patches Pixel Modem Flaw Amid Signs of Limited Targeted Exploitation

Google has disclosed that a high-severity security flaw in its Pixel Cellular Modem has come under exploitation in the wild. The vulnerability, tracked as CVE-2026-58704 (CVSS score: 8.0), is a privilege escalation flaw. "In Cellular Modem, there is a possible permission bypass due to a logic error in the code," according to a description of the bug in the NIST National Vulnerability Database (NVD). "This could lead to remote (proximal/adjacent) escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation." In an advisory issued Tuesday, Google acknowledged that it has found indications that "CVE-2026-58704 may be under limited, targeted exploitation" but stopped short of sharing any further details surrounding the nature of the attacks exploiting it, as well as the identity of the threat actor behind them. Besides CVE-2026-58704, Google has addressed 109 other security flaws as part of...
