Iran-Linked Hackers Breach FBI Director’s Personal Email, Hit Stryker With Wiper Attack

Mar 28, 2026 Hacktivism / Critical Infrastructure
Threat actors with ties to Iran successfully broke into the personal email account of Kash Patel, the director of the U.S. Federal Bureau of Investigation (FBI), and leaked a cache of photos and other documents to the internet. Handala Hack Team , which carried out the breach, said on its website that Patel "will now find his name among the list of successfully hacked victims." In a statement shared with Reuters, the FBI confirmed Patel's emails had been targeted, and noted necessary steps have been taken to "mitigate ​potential risks associated with this activity." The agency also said the published data was "historical in nature and involves no government information." The leak includes emails from ​2010 and 2019 allegedly sent by Patel. Handala Hack is assessed to be a pro-Iranian, pro-Palestinian hacktivist persona adopted by Iran's Ministry of Intelligence and Security ( MOIS ). It's tracked by the cybersecurity community under the m...

Citrix NetScaler Under Active Recon for CVE-2026-3055 (CVSS 9.3) Memory Overread Bug

Mar 28, 2026 Vulnerability / Network Security
A recently disclosed critical security flaw impacting Citrix NetScaler ADC and NetScaler Gateway is witnessing active reconnaissance activity, according to Defused Cyber and watchTowr . The vulnerability, CVE-2026-3055 (CVSS score: 9.3), refers to a case of insufficient input validation leading to memory overread, which an attacker could exploit to leak potentially sensitive information.

Apple Sends Lock Screen Alerts to Outdated iPhones Over Active Web-Based Exploits

Mar 27, 2026 Spyware / Mobile Security
Apple is now sending Lock Screen notifications to iPhones and iPads running older versions of iOS and iPadOS to alert users of web-based attacks and urge them to install the update. The development was first reported by MacRumors. "Apple is aware of attacks targeting out-of-date iOS software, including the version on your iPhone. Install this critical update to protect your iPhone," the notification issued by Apple reads. The development comes a week after Apple released a support document, asking users running older versions of iOS and iPadOS to update their devices following the discovery of new iOS exploit kits like Coruna and DarkSword . Multiple threat actors of varied motivations have been found to leverage these kits over the past year to deliver malicious payloads when unsuspecting users visit a compromised website. While Coruna targets iOS versions between 13.0 and 17.2.1, DarkSword is designed to target iPhones running iOS versions between 18.4 and 18.7. A...

TeamPCP Pushes Malicious Telnyx Versions to PyPI, Hides Stealer in WAV Files

TeamPCP Pushes Malicious Telnyx Versions to PyPI, Hides Stealer in WAV Files

Mar 27, 2026 Cybersecurity / Malware
TeamPCP, the threat actor behind the supply chain attack targeting Trivy , KICS , and litellm , has now compromised the telnyx Python package by pushing two malicious versions to steal sensitive data. The two versions, 4.87.1 and 4.87.2, published to the Python Package Index (PyPI) repository on March 27, 2026, concealed their credential harvesting capabilities within a .WAV file. Users are recommended to downgrade to version 4.87.0 immediately. The PyPI project is currently quarantined. Various reports from Aikido , Endor Labs , JFrog ,  Ossprey Security , SafeDep , Socket , and StepSecurity indicate the malicious code is injected into "telnyx/_client.py," causing it to be invoked when the package is imported into a Python application. The malware is designed to target Windows, Linux, and macOS systems. "Our analysis reveals a three-stage runtime attack chain on Linux/macOS consisting of delivery via audio steganography, in-memory execution of a data harvester, ...
Open VSX Bug Let Malicious VS Code Extensions Bypass Pre-Publish Security Checks

Open VSX Bug Let Malicious VS Code Extensions Bypass Pre-Publish Security Checks

Mar 27, 2026 Software Security / DevSecOps
Cybersecurity researchers have disclosed details of a now-patched bug impacting Open VSX's pre-publish scanning pipeline to cause the tool to allow a malicious Microsoft Visual Studio Code (VS Code) extension to pass the vetting process and go live in the registry. "The pipeline had a single boolean return value that meant both 'no scanners are configured' and 'all scanners failed to run,'" Koi Security researcher Oran Simhony said in a report shared with The Hacker News. "The caller couldn't tell the difference. So when scanners failed under load, Open VSX treated it as 'nothing to scan for' and waved the extension right through." Early last month, the Eclipse Foundation, which maintains Open VSX, announced plans to enforce pre-publish security checks before VS Code extensions are published to the repository in an attempt to tackle the growing problem of malicious extensions. With Open VSX also serving as the extension market...
AitM Phishing Targets TikTok Business Accounts Using Cloudflare Turnstile Evasion

AitM Phishing Targets TikTok Business Accounts Using Cloudflare Turnstile Evasion

Mar 27, 2026 Ransomware / Malware
Threat actors are using adversary-in-the-middle (AitM) phishing pages to seize control of TikTok for Business accounts in a new campaign, according to a report from Push Security. Business accounts associated with social media platforms are a lucrative target, as they can be weaponized by bad actors for malvertising and distributing malware. "TikTok has been historically abused to distribute malicious links and social engineering instructions," Push Security said . "This includes multiple infostealers like Vidar, StealC, and Aura Stealer delivered via ClickFix-style instructions with AI-generated videos posed as activation guides for Windows, Spotify, and CapCut." The campaign begins with tricking victims into clicking on a malicious link that directs them to either a lookalike page impersonating TikTok for Business or a page that's designed to impersonate Google Careers, along with an option to schedule a call to discuss the opportunity. It's worth n...

We Are At War

Mar 27, 2026 Hacktivism / Threat Intelligence
Rising geopolitical tensions are reflected (or in some cases preceded) by cyber operations, while technology itself has become politicized. Let’s admit it: we are in the middle of it.  Introduction: One tech power to rule them all is a thing of the past  The relative safety, peace and prosperity that much of the world has enjoyed since 1945 was not accidental. It emerged from the ashes of two world wars and the deliberate construction of a new global order. The United States of America set the terms of this new world. The long peace under Pax Americana provided a stable foundation, but that foundation is shifting. Europe’s deep strategic dependence on the U.S.’s technological and cybersecurity capabilities, from intelligence and infrastructure to frameworks and funding, is now being tested. Those tectonic geopolitical changes are undermining trust, threatening the state of safety, and compelling European organizations to rethink digital architectures and approaches at ever...

Bearlyfy Hits Russian Firms with Custom GenieLocker Ransomware

Mar 27, 2026 Threat Intelligence / Vulnerability
A pro-Ukrainian group called Bearlyfy has been attributed to more than 70 cyber attacks targeting Russian companies since it first surfaced in the threat landscape in January 2025, with recent attacks leveraging a custom Windows ransomware strain codenamed GenieLocker. "Bearlyfy (also known as Labubu) operates as a dual-purpose group aimed at inflicting maximum damage upon Russian businesses; its attacks serve the dual objectives of extortion for financial gain and acts of sabotage," Russian security vendor F6 said . The hacking group was first documented by F6 in September 2025 as leveraging encryptors associated with LockBit 3 (Black) and Babuk, with early intrusions focusing on smaller companies before upping the ante and demanding ransoms to the tune of €80,000 (about $92,100). By August 2025, the group had claimed at least 30 victims. Beginning May 2025, Bearlyfy actors also utilized a modified version of PolyVice , a ransomware family attributed to Vice Society ...
