At some point your security will fail. This isn’t pessimism. It’s not because your team and tools aren’t sophisticated enough. It’s the reason we have detections in the first place. And, it’s why once we accept that prevention has its limits, we arrive at an interdiction strategy: finding and disrupting what got in. After the alert The alert tells you something happened. However, gaining access to your network doesn’t necessarily mean attackers have stolen data or disrupted the systems they were targeting. They may need to obtain additional access, move to another machine, or further explore the network. Being able to see and understand that activity is the intervention opportunity. People naturally gravitate toward detections during product evaluations. They’re tangible, easy to compare and quantify, and address the question everyone wants an answer to: Will they catch the attack? There’s often an assumption that the rest will follow, meaning, if the detections are good, surely...

An iMessage flaw could let a remote attacker join a group chat and receive its messages, Apple said yesterday, and it released updates to fix it. The updates also fix a separate iMessage flaw that could let someone added to a group access messages sent before they joined. As of today, other updates released yesterday for the iPhone XS, XS Max and XR, the iPad (7th generation) and some Apple Watch models do not list either fix. The company's notes also do not say whether either flaw has been exploited, what an attacker would need, whether group members would see someone who joined this way, or whether every member must update to be protected. The updates that fix the iMessage flaws also fix a flaw in Google's Brotli compression library. The notes do not mention any attacks using that flaw. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added it to its Known Exploited Vulnerabilities catalog on October 27. The flaw that could let a remote attacker join ...

The Russia-aligned state-sponsored threat actor known as Turla (aka Snake) is wielding a previously undocumented cyber espionage toolset called Cereal that's used to break into victims' Microsoft Exchange servers with an aim to surreptitiously collect emails. According to an ESET report shared with The Hacker News ahead of publication, the sophisticated and modular tool is designed for long-term intelligence gathering and has been observed against two governmental entities in Kazakhstan and Romania in late 2025. "The Cereal toolset is a carefully constructed instrument for long-term, stealthy cyber espionage," the Slovakian cybersecurity company said . "It leaves little on disk, avoids external infrastructure that could be discovered and blocked, and conceals itself within legitimate Exchange processes." "The Cereal toolset demonstrates that, for Turla, Exchange servers are not just mail servers – they are durable collection points, internal e...

Four flaws that attackers could exploit without logging in were fixed today as part of SAP's monthly Security Patch Day—the vendor rates all four 10.0, the maximum CVSS score. Three are in the SAP NetWeaver application server, the software SAP systems run on, and one is in the Web Dispatcher, which receives web requests from the internet and passes them on to that server. The flaws in the Web Dispatcher and the Internet Communication Manager (ICM), which handles the server's web traffic, could allow an attacker who can reach the software over the network to run code, the vendor says. The flaw in the server's SAML 2.0 service provider, which hands off user sign-in to an identity provider, could allow an attacker to log in as any user on some systems that use SAML single sign-on. The flaw in SAP Gateway, which connects the server to other SAP systems and programs, could allow an attacker to impersonate one of the system's own servers and take unauthorized actions...

An October cyberattack on refrigeration controllers at about 700 French retail sites was carried out by a cyber unit of Iran's Islamic Revolutionary Guard Corps (IRGC), the French government said yesterday. The attackers broke into controllers on the night of October 11 and changed their defrost settings to high temperatures. That caused food losses and, in at least 15 cases, fires. The unit is called Shahid Kaveh . It is known mainly through hacktivist personas, such as CyberAveng3rs and Cyber Isnaad Front , that publicly claim some of its attacks, France says. France's Foreign Ministry plans to summon Iran's ambassador and to ask its European partners to adopt new sanctions against Iranian organizations and individuals involved in the attack. The Paris prosecutor's office opened a judicial investigation yesterday against the unit's head, the head's two deputies and anyone else identified. It has asked for international arrest warrants. The offenses u...

Anthropic on Monday released Claude Fable 5.2 and Claude Mythos 5.2 models, which it said exhibit improvements in coding, reasoning, and vision. During pre-release training, the large language models (LLMs) helped its engineers "complete otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in the physics of black holes, made substantial progress on robotics evaluations, and formalized the proof of Fermat’s Last Theorem in 30 hours." The artificial intelligence (AI) company said high-stakes risks arising from misalignment remain low, and claimed the models matched or performed better than Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1 on most alignment measures, resistance to misuse, honesty, and factuality. "It was roughly an order of magnitude less likely than Opus 5.5 and Sonnet 5.5 to publish harmful content to public package registries without encouragement, though it still did...
