Attackers uniquely fingerprint victims before delivering spear-phishing payloads aimed at espionage, in the latest campaign from the Belarussian nation-state threat group.

A threat actor with affiliations to China has been linked to a "multi-wave intrusion" targeting an unnamed Azerbaijani oil and gas company between late December 2025 and late February 2026, marking an expansion of its targeting. The activity has been attributed by Bitdefender with moderate-to-high confidence to a hacking group known as FamousSparrow (aka UAT-9244), which shares some level of

The cyberthreat group targets an Azerbaijani oil and gas firm with repeated attacks, as the China-linked actors extend targeting beyond hospitality, telecom, and government sectors.

In the latest evolution of automated cyberattacks, threat actors heavily leveraged AI agents to support campaigns against entities in Mexico and Brazil.

Foxconn, the world's largest electronics manufacturer, says some of its North American factories are now working to resume normal operations after a cyberattack. [...]

TL;DR: Stop chasing thousands of "toast" alerts. Join experts from Wiz to learn how hackers connect tiny flaws to build a "Lethal Chain" to your data—and how to break it. Register for the Strategic Briefing Here. Most security tools work like a smoke alarm that goes off every time you burn a piece of toast. You get so many alerts that you eventually start to ignore them. The real danger? While

Security teams have never had better visibility into their environments and never been worse at confirming what they fix stays fixed. Mandiant's M-Trends 2026 report puts the mean time to exploit at an estimated negative seven days. The Verizon 2025 DBIR puts median time to remediate edge device vulnerabilities at 32 days. These numbers have understandably driven the industry toward a clear

Microsoft on Tuesday released patches for 138 security vulnerabilities spanning its product portfolio, although none of them have been listed as publicly known or under active attack. Of the 138 flaws, 30 are rated Critical, 104 are rated Important, three are rated Moderate, and one is rated Low in severity. As many as 61 vulnerabilities are classified as privilege escalation bugs, followed by

Cybersecurity researchers are calling attention to a new campaign dubbed GemStuffer that has targeted the RubyGems repository with more than 150 gems that use the registry as a data exfiltration channel rather than for malware distribution. "The packages do not appear designed for mass developer compromise," Socket said. "Many have little or no download activity, and the payloads are repetitive,

Google on Tuesday unveiled a new opt-in Android feature called Intrusion Logging for storing forensic logs to better analyze sophisticated spyware attacks. Intrusion Logging, available as part of Advanced Protection Mode, enables "persistent and privacy-preserving forensics logging to allow for investigation of devices in the event of a suspected compromise," the company said. The feature, it

The U.S. House Committee on Homeland Security is calling on Instructure executives to testify about two cyberattacks by the ShinyHunters extortion group that targeted the company's Canvas platform, allowing threat actors to steal student data and disrupt schools during final exams. [...]

Artificial intelligence platforms may be just as susceptible to social engineering as human beings, but they are proving remarkably good at finding security vulnerabilities in human-made computer code. That reality is on full display this month with some of the more widely-used software makers -- including Apple, Google, Microsoft, Mozilla and Oracle -- fixing near record volumes of security bugs, and/or quickening the tempo of their patch releases.

It's the first time in two years with no zero-days. But with 137 flaws to patch, including nine critical ones, admins still have plenty of work to do.

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

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.

A tokenizer library file present in Hugging Face AI models can be manipulated to hijack the model's outputs and exfiltrate data.

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),
