Thousands of Public Google Cloud API Keys Exposed with Gemini Access After API Enablement

Feb 28, 2026Generative AI / API Security

New research has found that Google Cloud API keys, typically designated as project identifiers for billing purposes, could be abused to authenticate to sensitive Gemini endpoints and access private data. The findings come from Truffle Security, which discovered nearly 3,000 Google API keys (identified by the prefix "AIza") embedded in client-side code to provide Google-related services like embedded maps on websites. "With a valid key, an attacker can access uploaded files, cached data, and charge LLM-usage to your account," security researcher Joe Leon said , adding the keys "now also authenticate to Gemini even though they were never intended for it." The problem occurs when users enable the Gemini API on a Google Cloud project (i.e., Generative Language API), causing the existing API keys in that project, including those accessible via the website JavaScript code, to gain surreptitious access to Gemini endpoints without any warning or notice.

Pentagon Designates Anthropic Supply Chain Risk Over AI Military Dispute

Feb 28, 2026National Security / Artificial Intelligence

Anthropic on Friday hit back after U.S. Secretary of Defense Pete Hegseth directed the Pentagon to designate the artificial intelligence (AI) upstart as a "supply chain risk." "This action follows months of negotiations that reached an impasse over two exceptions we requested to the lawful use of our AI model, Claude: the mass domestic surveillance of Americans and fully autonomous weapons," the company said . "No amount of intimidation or punishment from the Department of War will change our position on mass domestic surveillance or fully autonomous weapons." In a social media post on Truth Social, U.S. President Donald Trump said he was ordering all federal agencies to phase out the use of Anthropic technology within the next six months. A subsequent X post from Hegseth mandated that all contractors, suppliers, and partners doing business with the U.S. military cease any "commercial activity with Anthropic" effective immediately. "I...

DoJ Seizes $61 Million in Tether Linked to Pig Butchering Crypto Scams

Feb 27, 2026Financial Crime / Social Engineering

The U.S. Department of Justice (DoJ) this week announced the seizure of $61 million worth of Tether that were allegedly associated with bogus cryptocurrency schemes known as pig butchering . The confiscated funds were traced to cryptocurrency addresses used for the laundering of criminally derived proceeds stolen from victims of cryptocurrency investment scams, the department added. "Criminal actors and professional money launderers use cyber-enabled fraud schemes to swindle their victims and conceal their ill-gotten gains," said HSI Charlotte Acting Special Agent in Charge Kyle D. Burns. "HSI special agents work diligently to trace the illicit proceeds of crime across the globe to disrupt and dismantle the transnational criminal organizations that seek to defraud hardworking Americans." As is the norm in such cybercrime operations, threat actors are known to target individuals by cultivating romantic relationships after approaching them on dating and social m...

900+ Sangoma FreePBX Instances Compromised in Ongoing Web Shell Attacks

Feb 27, 2026Network Security / Vulnerability

The Shadowserver Foundation has revealed that over 900 Sangoma FreePBX instances still remain infected with web shells as part of attacks that exploited a command injection vulnerability starting in December 2025. Of these, 401 instances are located in the U.S., followed by 51 in Brazil, 43 in Canada, 40 in Germany, and 36 in France. The non-profit entity said the compromises are likely accomplished via the exploitation of CVE-2025-64328 (CVSS score: 8.6), a high-severity security flaw that could enable post-authentication command injection. "The impact is that any user with access to the FreePBX Administration panel could leverage this vulnerability to execute arbitrary shell commands on the underlying host," FreePBX said in an advisory for the flaw in November 2025. "An attacker could leverage this to obtain remote access to the system as the asterisk user." The vulnerability affects FreePBX versions higher than and including 17.0.2.36. It was resolved in...

Malicious Go Crypto Module Steals Passwords, Deploys Rekoobe Backdoor

Feb 27, 2026Malware / Linux Security

Cybersecurity researchers have disclosed details of a malicious Go module that's designed to harvest passwords, create persistent access via SSH, and deliver a Linux backdoor named Rekoobe. The Go module, github[.]com/xinfeisoft/crypto, impersonates the legitimate "golang.org/x/crypto" codebase, but injects malicious code that's responsible for exfiltrating secrets entered via terminal password prompts to a remote endpoint, fetches a shell script in response, and executes it. "This activity fits namespace confusion and impersonation of the legitimate golang.org/x/crypto subrepository (and its GitHub mirror github.com/golang/crypto)," Socket security researcher Kirill Boychenko said . "The legitimate project identifies go.googlesource.com/crypto as canonical and treats GitHub as a mirror, a distinction the threat actor abuses to make github.com/xinfeisoft/crypto look routine in dependency graphs." Specifically, the backdoor has been placed with...

ScarCruft Uses Zoho WorkDrive and USB Malware to Breach Air-Gapped Networks

Feb 27, 2026Malware / Surveillance

The North Korean threat actor known as ScarCruft has been attributed to a fresh set of tools, including a backdoor that uses Zoho WorkDrive for command-and-control (C2) communications to fetch more payloads and an implant that uses removable media to relay commands and breach air-gapped networks. The campaign, codenamed Ruby Jumper by Zscaler ThreatLabz, involves the deployment of malware families, such as RESTLEAF, SNAKEDROPPER, THUMBSBD, VIRUSTASK, FOOTWINE, and BLUELIGHT to facilitate surveillance on a victim's system. It was discovered by the cybersecurity company in December 2025. "In the Ruby Jumper campaign, when a victim opens a malicious LNK file, it launches a PowerShell command and scans the current directory to locate itself based on file size," security researcher Seongsu Park said . "Then, the PowerShell script launched by the LNK file carves multiple embedded payloads from fixed offsets within that LNK, including a decoy document, an executable pa...

Trojanized Gaming Tools Spread Java-Based RAT via Browser and Chat Platforms

Feb 27, 2026Endpoint Security / Windows Security

Threat actors are luring unsuspecting users into running trojanized gaming utilities that are distributed via browsers and chat platforms to distribute a remote access trojan (RAT). "A malicious downloader staged a portable Java runtime and executed a malicious Java archive (JAR) file named jd-gui.jar," the Microsoft Threat Intelligence team said in a post on X. "This downloader used PowerShell and living-off-the-land binaries (LOLBins) like cmstp.exe for stealthy execution." The attack chain is also designed to evade detection by deleting the initial downloader and by configuring Microsoft Defender exclusions for the RAT components. Persistence is achieved by means of a scheduled task and Windows startup script named "world.vbs," before the final payload is deployed on the compromised host. The malware, per Microsoft, is a "multi-purpose malware" that acts as a loader, runner, downloader, and RAT. Once launched, it connects to an external ...

Meta Files Lawsuits Against Brazil, China, Vietnam Advertisers Over Celeb-Bait Scams

Feb 27, 2026Online Scam / Digital Advertising

Meta on Thursday said it's taking legal action to tackle scams on its platforms by filing lawsuits against what it calls deceptive advertisers based in Brazil, China, and Vietnam. As part of the effort, the advertisers' methods of payment have been suspended, related accounts have been disabled, and the website domain names used to pull off the scams have been blocked. Concurrently, the social media giant said it has also issued cease and desist letters to eight marketing consultants who advertised the ability to bypass its ad policy enforcement systems. This included fake "un-ban" or account restoration services and renting access to trusted accounts so as to help clients bypass its controls. At least three advertisers, two from Brazil and one from China, were found to engage in celeb-bait scams, which often involve misusing the image of well-known figures to trick people into clicking on bogus ads that lead to scam sites. These websites are designed to harvest ...

Aeternum C2 Botnet Stores Encrypted Commands on Polygon Blockchain to Evade Takedown

Feb 26, 2026Malware / Blockchain

Cybersecurity researchers have disclosed details of a new botnet loader called Aeternum C2 that uses a blockchain-based command-and-control (C2) infrastructure to make it resilient to takedown efforts. "Instead of relying on traditional servers or domains for command-and-control, Aeternum stores its instructions on the public Polygon blockchain," Qrator Labs said in a report shared with The Hacker News. "This network is widely used by decentralized applications, including Polymarket, the world's largest prediction market. This approach makes Aeternum's C2 infrastructure effectively permanent and resistant to traditional takedown methods." This is not the first time botnets have been found relying on blockchain for C2. In 2021, Google said it took steps to disrupt a botnet known as Glupteba that uses the Bitcoin blockchain as a backup C2 mechanism to fetch the actual C2 server address. Details of Aeternum C2 first emerged in December 2025, when Outpos...

UAT-10027 Targets U.S. Education and Healthcare with Dohdoor Backdoor

Feb 26, 2026Malware / Threat Intelligence

A previously undocumented threat activity cluster has been attributed to an ongoing malicious campaign targeting education and healthcare sectors in the U.S. since at least December 2025. The campaign is being tracked by Cisco Talos under the moniker UAT-10027 . The end goal of the attacks is to deliver a never-before-seen backdoor codenamed Dohdoor. "Dohdoor utilizes the DNS-over-HTTPS (DoH) technique for command-and-control (C2) communications and has the ability to download and execute other payload binaries reflectively," security researchers Alex Karkins and Chetan Raghuprasad said in a technical report shared with The Hacker News. Although the initial access vector used in the campaign is currently not known, it's suspected to involve the use of social engineering phishing techniques, leading to the execution of a PowerShell script. The script then proceeds to download and run a Windows batch script from a remote staging server, which, for its part, facilitat...

Expert Recommends: Prepare for PQC Right Now

Feb 26, 2026Encryption / Data Protection

Introduction: Steal It Today, Break It in a Decade Digital evolution is unstoppable, and though the pace may vary, things tend to fall into place sooner rather than later. That, of course, applies to adversaries as well. The rise of ransomware and cyber extortion generated funding for a complex and highly professional criminal ecosystem. The era of the cloud brought general availability of almost infinite amounts of storage. So there is literally nothing that stops criminals from stealing and trafficking heaps of data, be it encrypted or not.  Patient adversaries are employing a "Harvest Now, Decrypt Later" (HNDL) strategy. They are quietly accumulating encrypted data with the intention of decrypting it later using quantum computers. Any data requiring long-term security, such as trade secrets or classified designs, is vulnerable because its lifespan will inevitably outlive its current encryption. Therefore, it is crucial that organizations begin planning their PQC migrati...
