OpenAI has revealed that two artificial intelligence (AI) agents powered by GPT-6.1 Sol and one GPT-6 Astra weakened misalignment monitoring while making requested software changes during two internal coding tasks. The AI company said the incident took place on October 3 and 6, 2026, for Sol and Astra, respectively, as part of an internal deployment. "A GPT-6.1 Sol agent repairing an
PHP has released emergency updates that fix two critical flaws in the language itself, letting an attacker without an account run code on a web server. The fixes are in PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35, and the PHP team says only updating fully protects a server. The flaws, together called PHP2Shell, sit in the PHP runtime, not in any application, so a site is exposed even when its own
Google on Tuesday said it's rolling out improved safeguards in its Chrome browser to secure users against ClickFix attacks when Enhanced Protection is enabled. ClickFix is a popular social engineering technique in which bad actors trick users into copying and pasting malicious code directly into their computer's operating system, thereby bypassing conventional security controls. As part of
Cybersecurity researchers have disclosed details of a previously undocumented China-aligned threat cluster known as Bronze Sandcastle that has been observed targeting organizations in Asia and Africa since mid-2025. "The most distinctive technical marker for Bronze Sandcastle is its consistent use of Sandboxie DLL sideloading," Sophos security researcher Gabor Szappanos said in a post published
Generative AI has changed what a malicious email looks like. Messages that once gave themselves away through clumsy wording, generic pretexts, and reused templates now arrive fluent, personalized, and unique to each recipient, and the behavioral signals email filters have relied on for years are fading as a result. Proofpoint shared several examples of the shift at its Protect 2026 conference.
You cannot fully block the two critical PHP flaws called PHP2Shell before today's fix, and the one setting being passed around as a workaround is not enough on its own, the security firm that suggested it now says. PHP will release the fix at 14:00 UTC on October 21 for two flaws it rates 9.2 out of 10, and has given no workaround of its own. Until you can install it, what lowers your
An AppSec team can point an AI agent running on a general-purpose model at its own web apps with little setup. Sure, the model writes the attacks. But everything that makes those attacks safe to run against production and worth acting on afterward lives in the harness around the model. The harness is where the engineering in AI pentesting sits. The Hugging Face intrusion OpenAI disclosed in July
Attackers took control of more than 300 Tor exit relays in early October and used them to redirect SSH connections to servers that stole login passwords, a researcher found. Exit relays are the last hop in a Tor circuit, where traffic leaves the network for its destination. Only a password login to an SSH server made through Tor between October 1 and 5, after accepting the interception
Unknown threat actors breached TeamUpdraft's website and potentially gained unauthorized access to customers' connection keys for UpdraftCentral, UpdraftVault, and UpdraftClone, using them to backdoor WordPress sites. TeamUpdraft is the developer behind UpdraftPlus, a popular WordPress backup plugin with over four million active installations. The vendor also offers UpdraftCentral, a remote
U.S. federal civilian agencies must remove DeepSeek products from their information technology systems, along with any third-party products or services "developed using DeepSeek implementations," under a Department of Homeland Security order. They may also no longer buy information technology products or services from the Chinese AI developer or its affiliates Homeland Security Secretary
State Bank of India has identified 3,897 customer records containing personal information in a set of about 375,000 records available on the dark web, and it does not yet know where the data came from. The state-owned bank, India's largest, said in a stock-exchange filing dated October 21 that it "has experienced an incident involving the loss of certain data." The count is
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added four vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog, including four vulnerabilities impacting Plex Media Server that's collectively called Plex2Shell. The vulnerabilities are listed below - CVE-2026-96652 (CVSS score: 5.3) - Plex Media Server Server-Side Request Forgery (SSRF)
