DreamHost is warning of a data breach after attackers gained access to its File Manager platform for two months and stole customers' FTP/SFTP usernames and passwords. This follows the American web hosting provider and domain registrar's announcement that it suffered a cybersecurity incident requiring users to reset their email and FTP/SFTP passwords. In a data breach notification, DreamHost now says the breach extended from August 2026 to October 23, 2026, the day it was discovered. "We discovered that an unauthorized third party accessed the server that runs our web-based File Manager at files.dreamhost.com," reads the notification. "The unauthorized third party exploited a vulnerability in that software and was able to access the FTP/SFTP usernames and passwords of individuals who logged into this File Manager between approximately August 2026 and October 23, 2026."
Cyberattacks disrupted refrigeration monitoring systems at three French blood banks, amid similar attacks targeting European supermarkets. A cyberattack has hit three regional blood banks in France, disrupting systems used to monitor and control refrigerated storage facilities. The incident took place overnight between Sunday and Monday, at roughly the same time hackers were targeting supermarket refrigeration systems across several European countries. The attack is particularly concerning because it targeted infrastructure that plays a direct role in protecting public health. Blood products must remain within specific temperature ranges to preserve their quality and ensure they’re safe for medical use. A disruption to refrigeration systems can therefore have consequences that go well beyond a conventional IT outage. According to the French Health Ministry, the incident affected several facilities operated by the French Blood Establishment (EFS). “Several regional facilities of the French Blood Establishment (EFS) were affected by a cybersecurity incident that impacted certain cold storage room monitoring and control systems,” the health ministry said in a statement. “The incident had no impact on blood supplies,” Reuters reported, quoting EFS spokesperson Charley Dubois. Staff working around the clock received alerts about the problems and moved blood products to refrigerators that weren’t connected to the affected systems. This response helped prevent the incident from disrupting blood supplies, demonstrating how important operational procedures and contingency plans are when technology fails. “The situation was under control on Wednesday,” the French Health Ministry said, according to Reuters, which also reported that remote access to the affected refrigerators had been disabled. Investigations are now underway to establish how the attackers gained access, which equipment was affected and when the systems can safely return to normal operation. The timing is also significant. The French blood bank incident coincided with attacks against supermarket refrigeration systems in eight European countries, including Sweden and Belgium. Those attacks forced retailers to discard large quantities of food after hackers interfered with cooling and freezer systems. This wasn’t the first time French supermarkets had faced csxk cx incident. In October, police investigated an attack in which hackers allegedly seized control of cooling units at hundreds of supermarkets, causing fires and significant food losses. These incidents share similarities that deserve attention. They point to a security problem beyond traditional corporate IT systems: the growing exposure of operational technology (OT), including industrial control systems, refrigeration equipment, and the remote management platforms kdch operate them. These systems are often connected to corporate networks or accessible through remote management services. If attackers compromise those access points, they may be able to interfere with physical processes rather than simply steal information or encrypt business data. The consequences can be serious. In a supermarket, an attacker who manipulates refrigeration controls can cause food losses and potentially create safety risks. In a blood bank, the same type of interference could threaten the integrity of medical supplies and disrupt services that hospitals depend on. The French incident didn’t affect blood supplies, but the outcome shouldn’t lead organizations to underestimate the risk. Staff intervention and the availability of independent refrigerators helped contain the damage. Not every facility will have the same resources, response procedures or ability to move critical products at short notice. Organizations operating critical infrastructure need to treat the security of connected equipment as a core operational requirement. This means identifying exposed systems, restricting remote access, enforcing strong authentication, segmenting operational networks and monitoring changes to equipment settings. They also need tested manual procedures that allow essential services to continue when digital systems become unavailable or untrustworthy. The European Union has already raised concerns about vulnerabilities in connected infrastructure amid heightened security tensions following Russia’s invasion of Ukraine in 2022. These latest incidents reinforce the need to consider cyberattacks against physical systems as a real operational and public safety risk, not simply an IT problem. “Investigations are under way into how the attack was carried out, what equipment may have been affected and when systems can safely return to service.” concludes the report.

A large-scale watering hole attack associated with Russian hackers has been targeting iOS and Android users visiting compromised sites or fake ones impersonating legitimate portals. The campaign used multiple high-profile websites in the U.S., Ukraine, the Czech Republic, and Bulgaria that delivered the same payload for profiling visitors and their devices. This initial stage allows the attacker to determine the browser version to deploy "platform-specific n-day exploit chains without user interaction." Researchers at cybersecurity company Sekoia attribute the operation with moderate-to-high confidence to APT29 (aka Midnight Blizzard), a Russian threat group that was recently linked to hotel WiFi attacks. Based on their findings, compromised legitimate sites belong to a Ukrainian gas producer, a U.S. chemical industry trade association, and a Bulgarian military-related site.
A critical Android flaw could allow an attacker to run code on a phone without any user action remotely, Google said in its November security bulletin. The flaw, CVE-2026-58868, affects Android 14 through 17. Phones get the fix with security patch level 2026-11-01 or later, which phone makers and carriers send on their own schedules. As of November 4, Google's bulletin did not report
Developer platform WorkOS suffered a data breach after a threat actor accessed business contact records and summaries of customer communications. According to the company, the attacker used an AI offensive security framework to automate reconnaissance and exploitation attempts. Based on evidence from the investigation, no WorkOS app data or production services were accessed or affected. WorkOS is a developer infrastructure company that provides APIs, SDKs, and tools for integrating services such as enterprise authentication, single sign-on (SSO), user management, and identity management into applications. According to its website, at least 3,000 companies use its services, including OpenAI, Anthropic, Cursor, Perplexity, Snowflake, Plaid, Webglow, and Netlify. “On October 30, 2026, we identified unauthorized access to an internal WorkOS application used by our sales team,” the company says in an incident alert.
Large language model hijacking attacks, also known as LLMjacking, are generating large fraudulent cloud charges, with some organizations losing more than $100,000 per day. Companies can record costs as high as $1 million due to fraudulent calls using stolen API keys, researchers at Google's Threat Intelligence Group (GTIG) and Mandiant in analyzed incidents. Based on their observations, there are "two distinct operational clusters coordinating to compromise and monetize enterprise LLM infrastructure." The researchers identified two categories of threat actors: those who scan for publicly exposed LLM endpoints and those who steal valid API keys from unprotected machines. After gaining initial access, the attackers sell it to services known as LLM mixers, which provide their subscribers with unauthorized access to LLMs.
Synology warns of ransomware attacks exploiting a 2024 flaw in outdated NAS devices, urging users to update DSM immediately. A security fix released in 2024 is now at the centre of ransomware attacks against Synology NAS devices. The company has found attackers targeting systems that still run outdated versions of DiskStation Manager (DSM), putting files stored on these network storage devices at risk of encryption and extortion. Synology disclosed the attacks on October 29, 2026. Its investigation found that threat actors are taking advantage of a vulnerability that the vendor had already addressed in December 2024. “These attacks aim to encrypt data and extort ransom.” The warning highlights how devices left without security updates can remain exposed long after vendors have released a fix. The company hasn’t identified the exact vulnerability used in the attacks. Instead, it refers customers to Synology-SA-24:20, a security advisory published on November 5, 2024, which documents three flaws affecting DSM. The advisory was updated as fixes became available across different software branches, with the DSM 6.2 update released on December 5. The three vulnerabilities have different security implications. CVE-2024-10441 is the most severe, with a CVSS score of 9.8. It affects the system plugin daemon and could allow an unauthenticated remote attacker to execute arbitrary code on a vulnerable device. CVE-2024-50629 has a CVSS score of 5.3 and affects the DSM webapi component. It could allow remote attackers to read limited files. The third issue, CVE-2024-10445, is rated 4.3 and concerns improper certificate validation in the update functionality. It could allow an attacker in an adjacent network position to write limited files. Synology hasn’t confirmed which of these vulnerabilities attackers are exploiting. The three flaws should therefore be considered part of the security advisory, not three confirmed entry points in the current ransomware campaign. The vendor has released corrected builds for all the affected DSM branches. Users should check the full version number installed on their NAS and compare it with the minimum fixed releases listed in the advisory: DSM 7.2.2: 7.2.2-72806-1 or later. DSM 7.2.1: 7.2.1-69057-6 or later. DSM 7.2: 7.2-64570-4 or later. DSM 7.1: 7.1.1-42962-7 or later. DSM 6.2: 6.2.4-25556-8 or later. The impact of a ransomware infection on a NAS can extend well beyond the storage device itself. Businesses often use these systems to keep shared documents, operational files and backup copies in one place. If attackers encrypt that data, employees may lose access to essential information, while recovery can become much harder if the NAS also holds the backups needed to restore other systems. Updating DSM is therefore an immediate priority for administrators and home users alike. Synology is also advising customers to enable automatic updates so that future security fixes don’t depend entirely on someone checking for them manually. “Synology also recommends enabling automatic updates to keep DSM up to date at all times.” concludes the advisory.

A 3AM ransomware affiliate targeted a school estate in the UK and successfully encrypted around 37 of nearly 50 machines reached from an unmanaged host. Researchers at cybersecurity company Bitdefender believe the threat actor may have used AI-generated commands and an automated agentic loop to carry out the operation. The conclusion is based on a sequence of repeated commands that were slightly modified at each attempt and issued at roughly regular intervals of 40 to 100 seconds. "We were not able to access the machine the attacker worked from, so we cannot document anything about the language model itself: which model it was, whether it ran locally or remotely, or even whether a person was copying and pasting instructions and results between the implant and the model," Bitdefender explains.
