Grinex, a Kyrgyzstan-incorporated cryptocurrency exchange sanctioned by the U.K. and the U.S. last year, said it's suspending operations after it blamed Western intelligence agencies for a $13.74 million hack. The exchange said it fell victim to what it described as a large-scale cyber attack that bore hallmarks of foreign intelligence agency involvement. This attack led to the theft of over 1 billion rubles in user funds. "Digital forensic evidence and the nature of the attack point to an unprecedented level of resources and technological sophistication – capabilities typically available exclusively to the agencies of hostile states," the company said in a statement posted on its website. "Preliminary findings suggest the attack was coordinated with the specific objective of inflicting direct damage upon Russia's financial sovereignty." A spokesperson for the company went on to state that the exchange's infrastructure had been under attack since ...

Threat actors are exploiting security flaws in TBK DVR and end‑of‑life (EoL) TP-Link Wi-Fi routers to deploy Mirai -botnet variants on compromised devices, according to findings from Fortinet FortiGuard Labs and Palo Alto Networks Unit 42. The attack targeting TBK DVR devices has been found to exploit CVE-2024-3721 (CVSS score: 6.3), a medium-severity command injection vulnerability affecting TBK DVR-4104 and DVR-4216 digital video recording devices, to deliver a Mirai variant called Nexcorium . "IoT devices are increasingly prime targets for large-scale attacks due to their widespread use, lack of patching, and often weak security settings," security researcher Vincent Li said . "Threat actors continue exploiting known vulnerabilities to gain initial access and deploy malware that can persist, spread, and cause distributed denial-of-service (DDoS) attacks." This is not the first time the vulnerability has been exploited in the wild. Over the past year, the ...

Huntress is warning that threat actors are exploiting three recently disclosed security flaws in Microsoft Defender to gain elevated privileges in compromised systems. The activity involves  the exploitation of three vulnerabilities that are codenamed BlueHammer (requires GitHub sign-in), RedSun , and UnDefend , all of which were released as zero-days by a researcher known as Chaotic Eclipse (aka Nightmare-Eclipse) in response to Microsoft's handling of the vulnerability disclosure process. While both BlueHammer and RedSun are local privilege escalation (LPE) flaws impacting Microsoft Defender, UnDefend can be used to trigger a denial-of-service (DoS) condition and effectively block definition updates. Microsoft moved to address BlueHammer as part of its Patch Tuesday updates released earlier this week. The vulnerability is being tracked under the CVE identifier CVE-2026-33825 . However, the other flaws do not have a fix as of writing. In a series of posts shared on X, Hunt...

Google this week announced a new set of Play policy updates to strengthen user privacy and protect businesses against fraud, even as it revealed it blocked or removed over 8.3 billion ads globally and suspended 24.9 million accounts in 2025. The new policy updates relate to contact and location permissions in Android, allowing third-party apps to access the contact lists and a user's location in a more privacy-friendly manner. This includes a new Contact Picker, which offers a standardized, secure, and searchable interface for contact selection. "This feature allows users to grant apps access only to the specific contacts they choose, aligning with Android's commitment to data transparency and minimized permission footprints," Google said . Previously, apps requiring access to a specific user's contacts relied on READ_CONTACTS, an overly broad permission that granted apps the ability to access all contacts and their associated information. With the latest cha...

The National Institute of Standards and Technology (NIST) has announced changes to the way it handles cybersecurity vulnerabilities and exposures (CVEs) listed in its National Vulnerability Database (NVD), stating it will only enrich those that fulfil certain conditions owing to an explosion in CVE submissions. "CVEs that do not meet those criteria will still be listed in the NVD but will not automatically be enriched by NIST ," it said . "This change is driven by a surge in CVE submissions, which increased 263% between 2020 and 2025. We don’t expect this trend to let up anytime soon." The prioritization criteria outlined by NIST, which went into effect on April 15, 2026, are as follows - CVEs appearing in the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) Known Exploited Vulnerabilities (KEV) catalog. CVEs for software used within the federal government. CVEs for critical software as defined by Executive Order 14028: this includes soft...

An international law enforcement operation has taken down 53 domains and arrested four people in connection with commercial distributed denial-of-service (DDoS) operations that were used by more than 75,000 cybercriminals. The ongoing effort, dubbed Operation PowerOFF , disrupted access to the DDoS-for-hire services, took down the technical infrastructure supporting them, and obtained access to databases containing over 3 million criminal user accounts. Authorities are also sending warning emails and letters to the identified criminal users, and 25 search warrants have been issued. As many as 21 countries participated in the action: Australia, Austria, Belgium, Brazil, Bulgaria, Denmark, Estonia, Finland, Germany, Japan, Latvia, Lithuania, Luxembourg, the Netherlands, Poland, Portugal, Sweden, Thailand, the U.K., and the U.S. "Booter services allow users to launch DDoS attacks against targeted websites, servers, or networks," Europol said in a statement. "Their inf...

A recently disclosed high-severity security flaw in Apache ActiveMQ Classic has come under active exploitation in the wild, per the U.S. Cybersecurity and Infrastructure Security Agency (CISA). To that end, the agency has added the vulnerability, tracked as CVE-2026-34197 (CVSS score: 8.8), to its Known Exploited Vulnerabilities ( KEV ) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by April 30, 2026. CVE-2026-34197 has been described as a case of improper input validation that could lead to code injection, effectively allowing an attacker to execute arbitrary code on susceptible installations. According to Horizon3.ai's Naveen Sunkavally, CVE-2026-34197 has been "hiding in plain sight" for 13 years.  "An attacker can invoke a management operation through ActiveMQ's Jolokia API to trick the broker into fetching a remote configuration file and running arbitrary OS c...

Cybersecurity researchers have warned of an active malicious campaign that's targeting the workforce in the Czech Republic with a previously undocumented botnet dubbed PowMix since at least December 2025. "PowMix employs randomized command-and-control (C2) beaconing intervals, rather than persistent connection to the C2 server, to evade the network signature detections," Cisco Talos researcher Chetan Raghuprasad said in a report published today. "PowMix embeds the encrypted heartbeat data along with unique identifiers of the victim machine into the C2 URL paths, mimicking legitimate REST API URLs. PowMix has the capability to remotely update the new C2 domain to the botnet configuration file dynamically." The attack chain begins with a malicious ZIP file, likely delivered via a phishing email, to activate a multi-stage infection chain that drops PowMix. Specifically, it involves a Windows Shortcut (LNK) that's used to launch a PowerShell loader, which ...

You know that feeling when you open your feed on a Thursday morning and it's just... a lot? Yeah. This week delivered. We've got hackers getting creative in ways that are almost impressive if you ignore the whole "crime" part, ancient vulnerabilities somehow still ruining people's days, and enough supply chain drama to fill a season of television nobody asked for. Not all bad though. Some threat actors got exposed with receipts, a few platforms finally tightened things up, and there's research in here that's genuinely worth your time. Grab your coffee and keep scrolling. Targeted wallet breach Zerion Hack Likely Linked to North Korea Cryptocurrency wallet service Zerion has disclosed that one of its team member's devices was compromised, resulting in the theft of approximately $100K in stolen funds from internal company hot wallets. The company noted that user funds, Zerion apps, or infrastructure were...

In 2024, compromised service accounts and forgotten API keys were behind 68% of cloud breaches. Not phishing. Not weak passwords. Unmanaged non-human identities that nobody was watching. For every employee in your org, there are 40 to 50 automated credentials: service accounts, API tokens, AI agent connections, andOAuth grants. When projects end or employees leave, most of these stay active. Fully privileged. Completely unmonitored. Attackers don't need to break in. They just pick up the keys you left out. Join our upcoming webinar where we’ll show you how to find and eliminate these "Ghost Identities" before they become a back door for hackers. AI agents and automated workflows are multiplying these credentials at a pace security teams can't manually track. Many carry admin-level access they never needed. One compromised token can give an attacker lateral movement across your entire environment, and the average dwell time for...

Cisco has announced patches to address four critical security flaws impacting Identity Services and Webex Services that could result in arbitrary code execution and allow an attacker to impersonate any user within the service. The details of the vulnerabilities are below - CVE-2026-20184 (CVSS score: 9.8) - An improper certificate validation in the integration of single sign-on (SSO) with Control Hub in Webex Services that could allow an unauthenticated, remote attacker to impersonate any user within the service and gain unauthorized access to legitimate Cisco Webex services. CVE-2026-20147 (CVSS score: 9.9) - An insufficient validation of user-supplied input vulnerability in Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) that could allow an authenticated, remote attacker in possession of valid administrative credentials to achieve remote code execution by sending crafted HTTP requests. CVE-2026-20180 and CVE-2026-20186 (CVSS scores: 9.9) ...

A "novel" social engineering campaign has been observed abusing Obsidian, a cross-platform note-taking application, as an initial access vector to distribute a previously undocumented Windows remote access trojan called PHANTOMPULSE in attacks targeting individuals in the financial and cryptocurrency sectors. Dubbed REF6598 by Elastic Security Labs, the activity has been found to leverage elaborate social engineering tactics through LinkedIn and Telegram to breach both Windows and macOS systems, approaching prospective individuals on the professional social network under the guise of a venture capital firm and then moving the conversation to a Telegram group where several purported partners are present. The Telegram group chat is engineered to lend the operation a smidgen of credibility, with the members discussing topics related to financial services and cryptocurrency liquidity solutions. The target is then instructed to use Obsidian to access what appears to be a s...
