The Hacker News | #1 Trusted Source for Cybersecurity News

Stuff broke again. Not in a movie way. An old tool was left exposed. An abandoned package was abused. A deprecated feature was still running in prod. This week is the same lesson in a new form: phishing kits are easier to rent, AI names are useful bait, old login paths still fail, and forgotten software keeps becoming someone else's entry point. Scroll through the full Monday Cybersecurity Recap below for the news, tools, webinars, and fixes worth your time this week. ⚡ Threat of the Week Google Patches Actively Exploited Chrome 0-Day - Google released security updates to address 74 vulnerabilities, including one that has come under active exploitation in the wild. The high-severity vulnerability, tracked as CVE-2026-11645 (CVSS score: 8.8), has been described as an out-of-bounds memory access in V8, Chrome's JavaScript and WebAssembly engine.

Employee onboarding is a busy time for IT teams. New starters need devices, accounts, access permissions, and passwords, all delivered within a tight timeframe. That usually means sharing a temporary "first-day" password so employees can access systems for the first time. The issue is that these passwords don't always stay temporary. They may be sent over email or SMS, reused across accounts, or never changed at all, creating unnecessary risk during the onboarding process. For attackers, weak or poorly managed onboarding credentials can provide an easy route into corporate systems. To make the onboarding process more secure without slowing new employees down, it's important to understand why typical password-sharing methods introduce risk. When convenience overrides security The most common approach to sharing initial credentials with new employees is to send them in plain text over email or SMS. It's quick and convenient, especially during busy onboardin...

An attacker tampered with trusted JavaScript files used by WordPress sites running PushEngage , OptinMonster , and TrustPulse , turning those files into a way to break into the sites. When a site administrator was logged in as the file loaded, the code created an admin account under the attacker's control and installed a hidden plugin that opened a way back in. Ordinary visitors did not trigger it. Any site that was hit should be treated as compromised. All three plugins are run by one company, Awesome Motive, which had not commented on the two larger plugins as of June 15. Security firm Sansec disclosed the wider campaign on June 13, finding the same malicious code in JavaScript served for all three plugins. PushEngage followed a day later with its own incident notice , confirming an attacker had served tampered copies of its script and that sites loading them could be taken over. PushEngage, acquired by Awesome Motive years ago, is so far the only one of the three to ...

Cybersecurity researchers have disclosed details of fraudulent activity targeting users across the Middle East and North Africa by employing various fraudulent Facebook accounts impersonating politicians, public figures, and trusted organizations. "These accounts promoted fake offers, including free mobile internet packages, financial compensation, and government subsidy programs," Group-IB analysts Anna Yurtaeva and Viacheslav Shevchenko said . "Victims were encouraged to click embedded links to claim the advertised benefits, but were instead redirected through a chain of intermediary websites that ultimately led to phishing and traffic monetization infrastructure." The Singapore-headquartered cybersecurity company has these campaigns to Sniper Dz , a turnkey phishing-as-a-service (PhaaS) platform that was taken down last month in an INTERPOL-led operation. The findings indicate that the platform goes beyond facilitating credential theft, generating illicit ...

Palo Alto Networks has revealed that it has observed "active exploitation" of a recently disclosed PAN-OS vulnerability by an unknown threat actor to obtain unauthorized access to GlobalProtect portals. The vulnerability in question is CVE-2026-0257 (CVSS score: 7.8), an authentication bypass flaw affecting the portal and gateway components of PAN-OS software that could be exploited by bad actors to set up VPN connections. According to the network security company, the security defect could be exploited by a bad actor to bypass security controls and initiate VPN connections. The vulnerability has been exploited in the wild in limited attacks, with initial activity observed on May 17, 2026. It's currently unknown who is behind the exploitation efforts. "No post-access behavior or lateral movement has been identified as of this time," Palo Alto Networks said . "Only a small portion of the probed devices actually established VPN sessions, resulting ...

Splunk has released security updates to address a critical security flaw in Splunk Enterprise that could be exploited to conduct unauthenticated file operations and even remote code execution. The vulnerability, tracked as CVE-2026-20253 , is rated 9.8 on the CVSS scoring system. "In Splunk Enterprise versions below 10.2.4 and 10.0.7, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint," Splunk said in an alert this week. "The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials." The issue has been addressed in the following versions - Splunk Enterprise 10.0.0 to 10.0.6 - Fixed in 10.0.7 Splunk Enterprise 10.2.0 to 10.2.3 - Fixed in 10.2.4 Splunk Enterprise 10.4 - Not affected Splunk, which is part of Cisco, said Splunk Cloud is not impacted by the vulnera...

Anthropic said on Friday it will "abruptly disable" its most advanced artificial intelligence (AI) models, Claude Fable 5 and Mythos 5 , for all users after the U.S. government ordered it to suspend access to the models for foreign nationals, whether inside or outside the U.S., citing national security concerns. The AI company said it received an order at 5:21 p.m. ET, instructing it to suspend all access to the models by foreign nationals. It said that it believed there was a "misunderstanding" and that it is working to restore access to the models as soon as possible. Access to other models will not be affected by the export control directive. "Our understanding is that the government believes it has become aware of a method of bypassing, or 'jailbreaking' Fable 5," the company said. "We reviewed a demonstration of this specific technique being used to identify a small number of previously known, minor vulnerabilities. These vulner...

Attackers took over more than 400 packages in the Arch User Repository (AUR) this week and rewrote their build scripts to install a credential stealer on any machine that built them. The malware is a Rust binary built to harvest developer secrets. When it lands with root, it can also load an eBPF rootkit to hide itself. The AUR is Arch Linux's community package collection, and it is separate from the official Arch repositories, which were not affected. If you installed or updated an AUR package on or after June 11, check it against the current affected-package lists before trusting the host. The list of names is large, still growing, and not yet complete. This attack goes after the trust model, not a software flaw. The compromised packages kept their names, their histories, and the trust that came with them. Only the build instructions changed. The trap sat in the recipe, leaving the package itself looking exactly like the software users meant to install. No exploit, no ze...

Google on Friday said it's pursuing legal action against a Chinese cybercrime network, accusing it of using its Gemini artificial intelligence (AI) agent to send phishing text messages targeting Americans. The network is said to be behind the development and management of a phishing-as-a-service (PhaaS) software kit called Outsider, per the tech giant. "The operation weaponized Gemini to help generate fraudulent phishing pages and deploy massive SMS phishing ('smishing') attacks, often through text messages impersonating legitimate brands, alerting recipients of 'brokerage account issues' or insisting they are eligible for 'rewards through their mobile phone carrier,'" Google said . "The texts prompt users to click a link leading to a fraudulent website that mimics trusted institutions to steal personal and financial information." Google said it's filing the lawsuit to dismantle the network's infrastructure, and that it...

Instead of hiding on the laptops and servers defenders watch most closely, a China-nexus group spent close to a decade hidden inside the Linux login system itself. Sygnia, which tracks the group as Velvet Ant , says it backdoored the PAM and OpenSSH components that decide who is allowed to sign in, planting its access where ordinary cleanup could not reach it. The network it targeted had no direct internet access, so the group first staged through internet-facing systems to get there. The earliest traces go back to 2016. Instead of dropping new malware that a scanner might catch, the attacker changed the trusted login programs themselves. Nothing obvious appeared, and no exploit was needed, so the activity looked like normal administration. On many machines, the attacker replaced the main PAM login module with backdoored copies. Some let them in with a secret password; others quietly recorded real usernames and passwords as people logged in. Researchers found nine separate ver...

Cybersecurity researchers have described what they say is a new class of attack that can trick artificial intelligence (AI) coding agents into running arbitrary code on developer machines. Called Agentjacking by Tenet Security, the attack can be triggered by means of a fake error report crafted using Sentry, an open-source error-tracking and performance-monitoring platform. "The attack exploits a critical architectural flaw at the intersection of Sentry's event ingestion (which accepts arbitrary payloads from anyone with the DSN) and the Sentry MCP server (which returns this data to AI agents as trusted system output)," security researchers Ron Bobrov, Barak Sternberg, and Nevo Poran said . The idea is to inject crafted input into Sentry error events, which are then interpreted by coding agents like Claude Code and Cursor as legitimate diagnostic resolution steps and run attacker-controlled code. A successful attack of this kind can expose sensitive data, includ...
