Major providers are testing a quantum-safe version of HTTPS that shrinks certificates to one-tenth their previous size, decreasing latency and adding transparency.
ThreatsDay Bulletin is back on The Hacker News, and this week feels off in a familiar way. Nothing loud, nothing breaking everything at once. Just a lot of small things that shouldn’t work anymore but still do. Some of it looks simple, almost sloppy, until you see how well it lands. Other bits feel a little too practical, like they’re already closer to real-world use than anyone
Cybersecurity researchers have disclosed a new Android malware family called Perseus that's being actively distributed in the wild with an aim to conduct device takeover (DTO) and financial fraud. Perseus is built upon the foundations of Cerberus and Phoenix, at the same time evolving into a "more flexible and capable platform" for compromising Android devices through dropper apps distributed
Security teams have spent years building identity and access controls for human users and service accounts. But a new category of actor has quietly entered most enterprise environments, and it operates entirely outside those controls. Claude Code, Anthropic's AI coding agent, is now running across engineering organizations at scale. It reads files, executes shell commands, calls external APIs,
A new exploit kit for Apple iOS devices designed to steal sensitive data from is being wielded by multiple threat actors since at least November 2025, according to reports from Google Threat Intelligence Group (GTIG), iVerify, and Lookout. According to GTIG, multiple commercial surveillance vendors and suspected state-sponsored actors have utilized the full-chain exploit kit, codenamed DarkSword
These rulings prohibit the entities from entering or doing business in the European Union.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has urged government agencies to apply patches for two security flaws impacting Synacor Zimbra Collaboration Suite (ZCS) and Microsoft Office SharePoint, stating they have been actively exploited in the wild. The vulnerabilities in question are as follows - CVE-2025-66376 (CVSS score: 7.2) - A stored cross-site scripting
In episode 459 of Smashing Security, we dive into a chillingly clever account takeover attempt targeting WordPress co-founder Matt Mullenweg - involving MFA fatigue, real Apple alerts, a convincing support call, and a phishing page that oh-so-nearly worked. If a famous techie could have this happen to you, can you be sure you're immune? Plus: would you donate your lifetime medical history to science if you were promised anonymity? We unpack serious concerns around UK Biobank, where “de-identified” data may not be as anonymous as you think — and how surprisingly little information it takes to reveal everything. And! Human-powered “AI”, and a punishment worse than prison: eight hours on the RSA expo floor... All this, and much more, in episode 459 of the "Smashing Security" podcast with cybersecurity veteran Graham Cluley, and special guest Paul Ducklin.
In addition to enabling remote access, the malware supports a wide range of capabilities, including data theft and spying.
A sophisticated iOS exploit chain leverages multiple zero-day vulnerabilities and is targeting users in Saudi Arabia, Turkey, Malaysia, and Ukraine.
The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has sanctioned six individuals and two entities for their involvement in the Democratic People's Republic of Korea (DPRK) information technology (IT) worker scheme with an aim to defraud U.S. businesses and generate illicit revenue for the regime to fund its weapons of mass destruction (WMD) programs. "The North Korean
Amazon Threat Intelligence is warning of an active Interlock ransomware campaign that's exploiting a recently disclosed critical security flaw in Cisco Secure Firewall Management Center (FMC) Software. The vulnerability in question is CVE-2026-20131 (CVSS score: 10.0), a case of insecure deserialization of user-supplied Java byte stream, which could allow an unauthenticated, remote attacker to
A prompt injection vulnerability paired with other flaws can turn a Google search into a full attack chain that could threaten enterprise networks.
Tracking pixels let social media companies spy on their users even after they click over to advertiser sites, gleaning credit card info, geolocations, and more, according to an analysis.
The suspected India-linked threat group targets governments, telecom, and critical infrastructure using spear-phishing, old vulnerabilities, and rapidly rotating infrastructure to maintain persistent access.
Cybersecurity researchers have disclosed a critical security flaw impacting the GNU InetUtils telnet daemon (telnetd) that could be exploited by an unauthenticated remote attacker to execute arbitrary code with elevated privileges. The vulnerability, tracked as CVE-2026-32746, carries a CVSS score of 9.8 out of 10.0. It has been described as a case of out-of-bounds write in the LINEMODE Set
When a Magecart payload hides inside the EXIF data of a dynamically loaded third-party favicon, no repository scanner will catch it – because the malicious code never actually touches your repo. As teams adopt Claude Code Security for static analysis, this is the exact technical boundary where AI code scanning stops and client-side runtime execution begins. A detailed analysis of where Claude
Credential theft soared in the second half of 2025, thanks in part to the industrialization of infostealer malware and AI-enabled social engineering.
