Exim has released security updates to address a severe security issue affecting certain configurations that could enable memory corruption and potential code execution. Exim is an open-source Mail Transfer Agent (MTA) designed for Unix-like systems to receive, route, and deliver email. The vulnerability, tracked as CVE-2026-45185 (CVSS score: 9.8), aka Dead.Letter, has been described as a use-after-free vulnerability in Exim's binary data transmission (BDAT) message body parsing when a TLS connection is handled by GnuTLS. "The vulnerability is triggered during BDAT message body handling when a client sends a TLS close_notify alert before the body transfer is complete, and then follows up with a final byte in cleartext on the same TCP connection," Exim said in an advisory released today. "This sequence of events can cause Exim to write into a memory buffer that has already been freed during the TLS session teardown, leading to heap corruption. An attacker onl...

RubyGems , the standard package manager for the Ruby programming language, has temporarily paused account sign ups following what has been described as a "major malicious attack." "We're dealing with a major malicious attack on RubyGems right now," Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, said in a post on X. "Signups are paused for the time being. Hundreds of packages involved – mostly targeting us, but some carrying exploits." Visitors to RubyGems' sign up page are now greeted with the message: "New account registration has been temporarily disabled." Mend.io, which secures RubyGems, said it intends to release more details once the incident is contained. It's currently not known who is behind the attack. The development comes as software supply chain attacks targeting open-source ecosystems have been on the rise, with threat actors like TeamPCP compromising widely used packages ...

Cybersecurity researchers have flagged a new version of the TrickMo Android banking trojan that uses The Open Network (TON) for command-and-control (C2). The new variant, observed by ThreatFabric between January and February 2026, has been observed actively targeting banking and cryptocurrency wallet users in France, Italy, and Austria. "TrickMo relies on a runtime-loaded APK  (dex.module), used also by the previous variant, but updated with new features adding new network-oriented functionality, including reconnaissance, SSH tunnelling, and SOCKS5 proxying capabilities that allow infected devices to function as programmable network pivots and traffic-exit nodes," the Dutch mobile security company said in a report shared with The Hacker News. TrickMo is the name assigned to a device takeover (DTO) malware that's been active in the wild since late 2019. It was first flagged by CERT-Bund and IBM X-Force , describing its ability to abuse Android's accessibility ser...

Why do the Riskiest SOC Alerts Go Unanswered? Security operations teams are drowning in alerts. But the real problem isn't always alert volume; it's the blind spots. The most dangerous alerts are the ones no one is investigating. A recent report from The Hacker News examined why certain high-risk alert categories - WAF, DLP, OT/IoT, dark web intelligence, and supply chain signals- consistently go uninvestigated across enterprise SOCs. The findings point to a structural gap in how security coverage is delivered today: not a lack of tooling, but a ceiling built into every existing model. Your SOC Model Has a Coverage Ceiling In-house SOC teams are the first to feel the gap. Overloaded with high-volume, routine alerts, analysts rarely have the capacity, or the specialized expertise, to investigate WAF events, DLP anomalies, or signals from operational technology environments. These alert types require deep, domain-specific knowledge that most SOC teams simply don't have...

TeamPCP , the threat actor behind the recentsupply chain attack spree, has been linked to the compromise of the npm and PyPI packages from TanStack, UiPath, Mistral AI, OpenSearch, and Guardrails AI as part of a fresh Mini Shai-Hulud campaign. The affected npm packages have been modified to include an obfuscated JavaScript file ("router_init.js") that's designed to profile the execution environment and launch a comprehensive credential stealer capable of targeting cloud providers, cryptocurrency wallets, AI tools, messaging apps, and CI systems, including Github Actions, multiple reports from Aikido Security , Endor Labs , SafeDep , Socket , StepSecurity , and Snyk show. The data is exfiltrated to the "filev2.getsession[.]org" domain. Using Session Protocol infrastructure is a deliberate attempt on the part of the attackers to evade detection, as the domain is unlikely to be blocked within enterprise environments, given that it belongs to a decentralize...

Agentic AI is already running in production environments across many organizations today. It is executing tasks, consuming data, and taking actions — most likely without meaningful involvement from the security team. The industry conversation has largely framed this as a question of policy: allow it, restrict it, or monitor it? However, that framing misses the point.  The more urgent question is whether security professionals actually understand what they are dealing with. In most organizations, they don't right now. And that gap is compounding by the week. You cannot secure what you do not understand The foundational principle of information security has not changed: genuine fluency in a technology must come before you can meaningfully defend it. Think about firewalls. You cannot configure one well without understanding networking. When cloud computing arrived, organizations that skipped the foundational work ended up with environments they could not reason about — tools purc...

American educational technology company Instructure, the parent company of Canvas, said it reached an "agreement" with a decentralized cybercrime extortion group after it breached its network and threatened to leak stolen information from thousands of schools and universities. In an update shared on Monday, the Utah-based firm said it "reached an agreement with the unauthorized actor involved in this incident," citing "concerns about the potential publication of data." In taking the controversial decision to pay a ransom to avoid a leak, the company said the agreement covers all its impacted customers and that the pilfered data was returned to it, along with digital confirmation of data destruction. It also said it has been informed that none of the company's customers will be separately extorted as a result of the hack. "While there is never complete certainty when dealing with cyber criminals, we believe it was important to take every step...
