Monday starts with the usual promise that everything is under control. Then the logs wake up.
This week, trusted tools crossed lines, old flaws found new work, exposed systems stayed exposed, and attackers kept hiding inside normal-looking services. Nothing looked strange at first. That helped.
That is the mood. Here is the full recap.

OpenAI Says Its AI Agent Went Rogue
Cybersecurity researchers have flagged a Microsoft Teams-themed phishing campaign that employs "secure document" lures to deliver legitimate remote monitoring and management (RMM) tools.
"The victim was directed through compromised web infrastructure to a counterfeit Microsoft Store page claiming that Microsoft Teams had to be updated before the shared document could be opened," ZeroBEC said in
The China-linked cybercrime group behind the use of income tax-related phishing lures targeting Indian taxpayers, tax professionals, and corporate finance teams has been observed using a sophisticated crypter service called Cruciferra.
According to a new analysis by Proofpoint, Cruciferra has been utilized by various unrelated cybercriminal threat clusters to deliver a wide array of remote
Cybersecurity researchers have flagged fresh malicious cyber activity by a threat actor with ties to East Asia targeting government entities in the Middle East.
The intrusions have resulted in the deployment of previously unreported malware families dubbed TELESHIM, MIXEDKEY, and BINDCLOAK, according to Zscaler ThreatLabz. The cybersecurity firm said it detected the campaign earlier this month.
GitHub has announced a new cooldown mechanism in Dependabot, allowing the tool to wait at least three days after a release is published before opening a pull request.
"The cooldown configuration option in the dependabot.yml still controls the behavior, though, so you can choose a different cooldown parameter that fits your project," the Microsoft-owned subsidiary said.
According to GitHub, the
Threat actors linked to the Cl0p (aka Chubby Scorpius, FIN11, Graceful Spider, and Lace Tempest) ransomware campaign are exploiting flaws in internet-exposed PTC Windmill and FlexPLM deployments as part of a new data extortion campaign.
"Attackers chain a pre-authentication information disclosure in the FlexPLM WSDL endpoint with a server-side flaw in the Windchill login servlet, enabling
The operators of the DevMan ransomware-as-a-service (RaaS) scheme are maintaining a dedicated web platform that offers affiliates the ability to build payloads, oversee earnings, and manage various aspects related to victims.
Swiss cybersecurity company PRODAFT is tracking the centrally administered RaaS operation under the name Funky Mantis.
"The portal combined build generation, finance,
The North Korean threat actors behind the ClickFix-style campaigns that employ typosquatted Zoom and Microsoft Teams domains have been found to operate an active phishing kit to impersonate the videoconferencing platforms in social engineering campaigns designed to deliver malware.
"BlueNoroff has operationalised trust abuse by combining compromised industry contacts, social engineering, wallet
Cybersecurity researchers have disclosed a critical vulnerability in OpenAI's ChatGPT Workspace Agents that could have allowed a single phishing link to stealthily build, authorize, and deploy an autonomous artificial intelligence (AI) agent inside a victim's organization.
The vulnerability has been codenamed AgentForger by Zenity Labs. The issue has since been addressed by OpenAI as of June 8,
The threat actors behind the Golden Chickens malware-as-a-service (MaaS) ecosystem have resurfaced with four new malware families, indicating that the operators are showing no signs of stopping despite extensive public disclosures into their inner workings.
The malware families in question are: TinyEgg, ChonkyChicken, a modularized variant of ChonkyChicken, and a modified web browser credential
The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new campaign that involves the use of a malicious program that's dressed up as a Notepad++ plugin to compromise Windows systems.
The activity has been attributed by the agency to a threat cluster it tracks as UAC-0099, a Russia-aligned group that has previously observed weaponizing security flaws in WinRAR software to
Most of this week's trouble came dressed as something useful.
A package stole data. A fake extension opened remote access. A safety app became spyware. An image gave hidden orders to an AI agent. Other threats hid in open systems, weak code, and normal network traffic.
The threats change every week. Subscribe, and weβll alert you when each new ThreatsDay Bulletin is out.
The danger was
Cybersecurity researchers have uncovered a sandbox escape vulnerability in Anthropic's Claude Cowork that makes it possible to break out of the confines of a Linux virtual machine (VM) within which the agent runs to read or write files anywhere on the Mac.
Accomplish AI, which shared details of the vulnerability with The Hacker News ahead of publication, said about 500,000 macOS users running
Cybersecurity researchers have shed light on a large-scale campaign that has turned compromised GitHub repositories into distributed attack infrastructure designed to target cPanel and WebHost Manager (WHM) instances.
The activity involves malicious Packagist development versions spanning 10 packages associated with a legitimate PHP and DevOps developer, dinushchathurya, between July 12 and 13,
Google on Thursday announced a new way for users to sign-in to their accounts by letting them take a selfie video.
The selfie for sign-in, per the tech giant, is another option on top of existing recovery methods to log in to an account, including an email address or a phone number. The idea is to use a video selfie as a way to regain access if a user ever gets locked out or doesn't have access
Check Point has released security updates to address multiple vulnerabilities impacting Security Management and Multi-Domain Management (MDSM) products, including a critical flaw that has come under active exploitation in the wild.
The security flaw, tracked as CVE-2026-16232 (CVSS score: 9.3), is an authentication bypass affecting the Check Point SmartConsole login process that allows an
Cybersecurity researchers have disclosed details of a new local privilege escalation (LPE) vulnerability in snap-confine that an unprivileged user can trigger to obtain root access and gain complete control of a target environment.
The high-severity flaw, tracked as CVE-2026-8933 (CVSS score: 7.8), impacts default installations of Ubuntu Desktop 24.04, 25.10, and 26.04. The disclosure comes as
Cybersecurity researchers have disclosed details of a now-patched vulnerability chain in the Adobe Acrobat Chrome extension that has over 314 million users, which, if exploited, could facilitate a silent hijack of a user's WhatsApp data.
The shortcoming has been codenamed HermeticReader by Guardio Labs. It's officially tracked as CVE-2026-48294 (CVSS score: 7.4), with the vulnerability
A high-severity security flaw impacting open-source developer platform Windmill has come under active exploitation in the wild, per VulnCheck.
The vulnerability in question is CVE-2026-29059 (CVSS score: 7.5), a case of unauthenticated path traversal impacting Windmill's "get_log_file" endpoint ("/api/w/{workspace}/jobs_u/get_log_file/{filename}").

OpenAI on Tuesday said a combination of its artificial intelligence (AI) models, including GPT-5.6 Sol and an "even more capable pre-release model," was behind the security incident that targeted Hugging Face's production infrastructure last week.
The AI company said the models were operating with "reduced cyber refusals for evaluation purposes" that might otherwise limit their ability to
