Proofpoint has disclosed details of a targeted email campaign in which threat actors with ties to Russia are leveraging the recently disclosed DarkSword exploit kit to target iOS devices. The activity has been attributed with high confidence to the Russian state-sponsored threat group known as TA446, which is also tracked by the broader cybersecurity community under the monikers Callisto,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a critical security flaw impacting F5 BIG-IP Access Policy Manager (APM) to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability in question is CVE-2025-53521 (CVSS v4 score: 9.3), which could allow a threat actor to achieve remote code execution. "When a

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 "Apple is aware of attacks targeting out-of-date iOS software, including the version on your iPhone.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

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

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

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

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

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;

Cybersecurity researchers have disclosed three security vulnerabilities impacting LangChain and LangGraph that, if successfully exploited, could expose filesystem data, environment secrets, and conversation history. Both LangChain and LangGraph are open-source frameworks that are used to build applications powered by Large Language Models (LLMs). LangGraph is built on the foundations of

World Leaks is a cyber extortion operation that steals sensitive data from organizations and threatens to leak it via the dark web if a ransom is not paid. Read more in my article on the Fortra blog.

A long-term and ongoing campaign attributed to a China-nexus threat actor has embedded itself in telecom networks to conduct espionage against government networks. The strategic positioning activity, which involves implanting and maintaining stealthy access mechanisms within critical environments, has been attributed to Red Menshen, a threat cluster that's also tracked as Earth Bluecrow,

Most teams have security tools in place. Alerts are firing, dashboards look clean, threat intel is flowing in. On the surface, everything feels under control. But one question usually stays unanswered: Would your defenses actually stop a real attack? That’s where things get shaky. A control exists, so it’s assumed to work. A detection rule is active, so it’s expected to catch something. But very

Cybersecurity researchers have disclosed a vulnerability in Anthropic's Claude Google Chrome Extension that could have been exploited to trigger malicious prompts simply by visiting a web page. The flaw "allowed any website to silently inject prompts into that assistant as if the user wrote them," Koi Security researcher Oren Yomtov said in a report shared with The Hacker News. "No clicks, no

Unmasking impostors is something the art world has faced for decades, and there are valuable lessons from the works of Elmyr de Hory that can apply to the world of defensive cybersecurity. During the 1960s, de Hory gained infamy as a premier forger, passing off counterfeit masterworks of Picasso, Matisse, and Renoir to unsuspecting collectors and renowned museums. Over the next several decades,

Some weeks in security feel loud. This one feels sneaky. Less big dramatic fireworks, more of that slow creeping sense that too many people are getting way too comfortable abusing things they probably shouldn’t even be touching. There’s a little bit of everything in this one, too. Weird delivery tricks, old problems coming back in slightly worse forms, shady infrastructure doing

A disgruntled data analyst decides that the best response to losing his contract is to steal the entire company payroll database and demand $2.5 million in Bitcoin - signing his extortion emails from a company called "Loot." Meanwhile, two people drive up to the entrance of the UK's nuclear submarine base at Faslane and politely ask if they can have a look around. Tourists? Spies? Something in between? All this and more in episode 460 of the "Smashing Security" podcast with cybersecurity veteran Graham Cluley, and special guest Jenny Radcliffe.

The kernel exploit for two security vulnerabilities used in the recently uncovered Apple iOS exploit kit known as Coruna is an updated version of the same exploit that was used in the Operation Triangulation campaign back in 2023, according to new findings from Kaspersky. "When Coruna was first reported, the public evidence wasn't sufficient to link its code to Triangulation — shared

Cybersecurity researchers have discovered a new payment skimmer that uses WebRTC data channels as a means to receive payloads and exfiltrate data, effectively bypassing security controls. "Instead of the usual HTTP requests or image beacons, this malware uses WebRTC data channels to load its payload and exfiltrate stolen payment data," Sansec said in a report published this week. The attack,

The alleged administrator of the LeakBase cybercrime forum has been arrested by Russian law enforcement authorities, state media reported Thursday. According to TASS and MVD Media, a news website linked to the Russian Interior Ministry, the suspect is a resident of the city of Taganrog. The suspect is said to have been detained for creating and managing a criminal site that allowed stolen

Cybersecurity researchers have flagged a new evolution of the GlassWorm campaign that delivers a multi-stage framework capable of comprehensive data theft and installing a remote access trojan (RAT), which deploys an information-stealing Google Chrome extension masquerading as an offline version of Google Docs. "It logs keystrokes, dumps cookies and session tokens, captures screenshots, and
