Certificate authority eMudhra revoked eight compromised intermediate certificates after researchers found their private keys were so weak that anyone could recover them almost instantly and use them to forge trusted certificates for legitimate websites.
The PHP security team is warning administrators to prepare for emergency security updates tomorrow to address two critical vulnerabilities, as information about the flaws has reportedly leaked ahead of their scheduled disclosure. PHP powers many websites and web applications, including content management systems, e-commerce platforms, and custom web services. In an advisory published Tuesday, the PHP development team announced that it plans to release security updates on Wednesday, October 21, at 14:00 UTC (10:00 AM Eastern), to address two vulnerabilities, each rated 9.2 under CVSS v4.0. The PHP security team also sent a notice to its ANNOUNCE mailing list, urging administrators to prepare to install the security updates as soon as they become available. "We reserve the right to release earlier should details of either vulnerability become public, or should evidence of active exploitation appear in the wild," the PHP security team warned.
Development platform Zeabur has disclosed details of a cybersecurity incident in which an attacker used leaked internal credentials stored in plaintext to compromise its infrastructure and steal over 3.2 million environment variable records and information for 321,810 accounts.
OpenAI confirmed that its newer models are much better at writing and migrating software in older programming languages. The company lists programming languages such as COBOL, Fortran, and Visual Basic as a few examples where it has seen significant improvements. OpenAI says COBOL supports more than 40% of online banking systems, 80% of in-person credit card transactions, and 95% of ATM transactions, while Fortran is still used in areas such as weather forecasting and nuclear reactor safety analysis. "These languages have less code and documentation available for models to learn from than languages like Python and JavaScript, yet support critical infrastructure and essential services around the world," OpenAI explained in a blog post. To measure progress, OpenAI created MultiLangBench, which asks models to build a SQLite-compatible database engine from scratch across 20 programming languages.
The private keys of eight eMudhra intermediate certificate authority (CA) certificates are compromised, Mozilla and Google's Chrome Root Program confirms on October 20. An intermediate CA signs the certificates that websites present, so anyone holding one of these keys could issue a certificate for any website that a browser would accept. A researcher reported the
Google Cloud’s London outage disrupted Revolut payments and ATM withdrawals, while ING Germany reported online banking issues. Multiple Google Cloud services went offline in the London region this morning, according to Google’s status page, and the disruption didn’t stay contained to infrastructure dashboards. BREAKING: Revolut's app and cards have stopped working across Europe. Google Cloud's London region is affected by network failures. Revolut, and many other services, runs on Google Cloud. Revolut says money and data are safe but has not named a cause. pic.twitter.com/kyxOMlVaak — International Cyber Digest (@IntCyberDigest) October 20, 2026 British digital bank Revolut reported a widespread service outage at roughly the same time, and a person familiar with the matter told Reuters the two events were directly connected. “Multiple Google Cloud services experienced disruptions in the company’s London region on Tuesday, according to its service status page, while British digital bank Revolut also reported a service outage.” Reuters states, “A person familiar with the matter told Reuters that Revolut’s service outage was related to the Google Cloud service disruption.” The outage affected Google’s europe-west2 data center, its main facility in London. Google’s engineering team said they were investigating the problem. Alphabet did not immediately respond to Reuters’ request for more information. This is common during an ongoing incident, but it leaves customers unsure when their cards will work again. Revolut’s own status page showed most services as unavailable or partially unavailable, including card payments and ATM withdrawals. For a bank that exists entirely as an app with no physical branches to fall back on, that’s not a minor inconvenience. “We are currently experiencing a service disruption affecting multiple services. We can confirm that all our customers’ money and data are safe. We’ve been working to fix the issue since it was identified this morning and apologise to anyone affected and for any inconvenience.” the financial company wrote on X. We are currently experiencing a service disruption affecting multiple services. We can confirm that all our customers’ money and data are safe. We’ve been working to fix the issue since it was identified this morning and apologise to anyone affected and for any inconvenience… — Revolut (@Revolut) October 20, 2026 That last sentence is the right thing to say, and it’s also exactly what every bank says during an outage regardless of whether the underlying cause is confirmed. Money and data being safe is a different question from whether you can pay for your coffee. ING Germany also reported problems on Tuesday. Customers had trouble logging into online banking and the mobile app because of a technical issue. Reuters did not link these problems to the Google Cloud outage, and ING has not explained the cause. Two major financial services companies experiencing problems on the same morning could be a coincidence. However, it also raises questions about how much European banks depend on a small number of cloud providers. Google Cloud’s europe-west2 region in London supports many UK and European fintech services. Revolut alone serves tens of millions of customers across Europe. When a major data center goes down, the impact can quickly reach customers, preventing them from paying or accessing banking services before the cause is fully understood.

Cybersecurity researchers have released a proof-of-concept (PoC) exploit for a recently patched critical security flaw impacting Fortinet FortiSIEM that could result in arbitrary code execution. The vulnerability, tracked as CVE-2026-106173 (CVSS score: 9.4), is a critical path traversal flaw that could allow an unauthenticated attacker to execute unauthorized code or commands via specially
The U.S. Department of Homeland Security (DHS) is ordering federal civilian agencies to stop using DeepSeek products and remove them from government systems. The order also covers products from the Chinese AI company's affiliates and third-party products and services built using DeepSeek technology. DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd) develops large language models and offers a chatbot, API services, and models suitable for coding and reasoning tasks. Its AI tools became extremely popular early on, but were but were soon followed by reports of security risks [1, 2, 3, 4] and concerns about the potential for Chinese authorities to access users’ conversations. The DHS is now taking regulatory action to limit the use of DeepSeek and derivatives on critical systems in the United States, and has issued a notice of order for agencies to:
A Chinese-speaking criminal pointed autonomous AI agents at company websites and let them break in with almost no help, and a security researcher watched it happen because the operators left their control panels open on the internet. The agents tried more than 1,200 sites and reached websites belonging to more than 100 companies, including farm-equipment maker Deere, appliance company
The iPhone of Vladan Đokić, rector of the University of Belgrade and a prominent supporter of Serbia's student protest movement, was infected with NSO Group's Pegasus spyware in 2026, the Citizen Lab said on October 19. The finding came six days before Serbia's October 25 snap parliamentary election. The infection used a zero-click exploit, meaning Đokić did not have to tap a link or
