Apple (11%), Google (9%), Amazon (7%) and LinkedIn (6%) followed, reflecting attackers’ focus on both enterprise and consumer ecosystems tied to identity, devices and payments. The report underscores a persistent trend: threat actors exploit trusted brands to harvest credentials and gain initial access to personal and corporate environments.

🔒 A new report from Halcyon warns that ransomware has become the fastest-growing and most disruptive cyber threat to the automotive sector, accounting for 44% of attacks on carmakers in 2025 after incidents more than doubled that year. The vendor links the surge to connected vehicle platforms, OTA update mechanisms, cloud services and insecure third-party suppliers. Recommended mitigations include patching edge devices, deploying phishing-resistant MFA, hardening EDR, maintaining immutable offline backups and enforcing supplier security requirements.

🔒 Google Threat Intelligence reports a sharp rise in data leak site (DLS) activity targeting Germany, with German victim posts growing 92% in 2025—triple the European average. Attackers have shifted focus to the digitized industrial base and the Mittelstand, exploiting mid‑tier DLS groups such as SAFEPAY and Qilin. GTI observed forum recruitment and extortion tactics traced to actors like Sarcoma. Caveats note that DLS counts often reflect failed negotiations and are one signal among many; GTI recommends proactive third‑party risk management, multifactor authentication, and endpoint hardening.

⚠️ Cisco Talos details how attackers are misusing the AI workflow automation platform n8n to run sophisticated phishing and malware campaigns. Between October 2025 and March 2026, researchers observed a sharp increase in emails containing n8n webhook URLs that serve dynamic HTML payloads and CAPTCHA-protected bait to initiate downloads. These flows mask malicious payloads behind trusted domains and have been used to deploy modified RMM tools and to fingerprint recipients. Talos urges behavioral detection, IOC sharing, and AI-enhanced email defenses to mitigate this abuse.

🔍 Talos' 2025 Year in Review documents state-sponsored activity from China, Russia, North Korea, and Iran, each pursuing different goals such as espionage, disruption, and financial gain. Despite varied motives, adversaries consistently exploit both newly disclosed and long-known vulnerabilities, and rely on identity-based access and stealthy persistence. Notable examples include rapid exploitation and web shells from China, geopolitically timed campaigns and common malware families from Russia, North Korean social-engineering and a $1.5B crypto theft, and Iran's mix of visible disruption and stealthy APT activity such as ShroudedSnooper. Defenders are urged to prioritise patching, identity security, network visibility, and hunts for long-term presence.

🛡️ Quantum computing is moving from theoretical risk to an imminent threat that undermines current cryptographic protections. Advances in algorithms and reduced qubit requirements mean timelines once measured in decades are now years, prompting Gartner in late 2025 to elevate Post-Quantum Cryptography migration to a board-level priority ahead of 2030. Organizations must inventory sensitive assets, prioritize store-now-decrypt-later risks, and begin crypto-agility planning immediately.

🔒 Vice Admiral Thomas Daum warned that hybrid attacks on Germany's critical infrastructure and Bundeswehr forces abroad have risen noticeably since 2022. At NATO's Locked Shields exercise he cited targeted intrusions against Bundeswehr data centres, alleged phone tapping of deployed personnel and disinformation campaigns in Lithuania. Authorities suspect state actors including Russia, China, Iran and North Korea, while energy firms, banks and local authorities remain at risk.

🔒 Researchers report that the JanelaRAT malware, a modified BX RAT, extensively targeted banks and financial services across Latin America, with telemetry showing 14,739 attack attempts in Brazil and 11,695 in Mexico during 2025. The trojan steals banking and cryptocurrency credentials, captures keystrokes, screenshots and system metadata, and uses custom title-bar detection to trigger actions on matched sites. Attackers shifted delivery from VBScript ZIPs to rogue MSI installers and DLL side-loading, often installing a malicious Chromium extension for persistence and data exfiltration. Vendors including Kaspersky, KPMG, and Zscaler documented multi-stage chains and robust C2 capabilities.

🔍 German authorities have identified the operator of the notorious GandCrab ransomware as Danii Shchukin, who used the aliases UNKN and Unknown and is believed to have led the GandCrab/Revi group. Europol has added Shchukin and an associate, Anatoly Kravchuk, to its most-wanted list amid allegations of organized and commercial extortion dating to 2019. German police say Shchukin is accused in 130 cases, with €1.9 million paid in 25 incidents and total economic damage estimated at €35.4 million; both suspects are believed to be in Russia but could be operating in other countries.
