ConnectWise has shut down customer access to its Cloud Backup service (formerly SkyKick Cloud Backup) after hackers accessed application identities and compromised Microsoft 365 tenants. Reports of the malicious activity began emerging on Friday, with administrators observing unauthorized access to client data in Microsoft 365 tenants due to a potential “SkyKick/CW breach.” Later on the same day, managed cybersecurity and threat detection platform Huntress confirmed the worries, saying that it had identified at least 162 compromised tenants in its environment. In a post today, Microsoft also confirmed malicious activity involving ConnectWise’s Cloud Backup service, saying it identified unauthorized authentication attempts from an IP address on October 15. ConnectWise’s cloud backup solutions provide backup and recovery services that help managed service providers (MSPs) and IT teams protect and restore customer data, such as emails and files, in cloud environments including Microsoft 365 and Google Workspace.
Drupal has patched two critical vulnerabilities that could allow attackers to execute code remotely on websites running any supported version of the content management system. The security issues impact the software core's Field UI module and the contributed Entity List module. Drupal issued an advance warning at the beginning of the week, urging administrators to apply updates promptly because attackers could develop exploits shortly after the vulnerabilities’ disclosure. “The Drupal Security Team urges you to reserve time for core updates at that time because exploits might be developed within hours or days,” the project's security team warned. “We recommend updating to the latest supported patch (bugfix) release for your site's version of Drupal before October 14, so that you can address any other upgrade issues before the security window.”
A cyber incident at a BAE Systems subsidiary just stopped every bankruptcy court in the US from sending notices, and the problem started a week ago. A security incident at BAE Systems Inc., the US subsidiary of British defense contractor BAE Systems, has taken the Bankruptcy Noticing Center offline since October 9. The Bankruptcy Noticing Center (BNC) is the system that federal bankruptcy courts use to send official notices. It handles court notices, messages to creditors, and deadline notifications that keep everyone involved in a case informed. “BAE Systems IT and websites that support the operations of the Bankruptcy Noticing Center (BNC) have been impacted by a cybersecurity incident.” reads the official judiciary statement. “As a result of the incident, all access to the BNC systems and websites that BAE operates on behalf of the judiciary and the related bankruptcy noticing process are unavailable at this time, including bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service. The incident has also halted the BNC’s production and distribution of bankruptcy notices for bankruptcy courts.” The disruption has prevented the center, which BAE operates on behalf of the federal judiciary, from generating and sending notices to creditors, courts, and attorneys in federal bankruptcy cases across the country. This is not a minor service disruption. The entire notification system used by federal bankruptcy courts across the country is down. “Several online services supporting US federal courts’ bankruptcy systems have gone offline following a cybersecurity incident involving a court contractor, the Administrative Office of the US Courts (AOC) said on Thursday.” Reuters reported. The US judiciary explained that the BNC sends bankruptcy notices for every federal bankruptcy court in the country. Affected domains include bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service. With that last one down, attorneys using the electronic filing system can’t generate the creditor mailing lists they normally need to serve documents. Courts are still accepting new case filings and electronic notifications to registered attorneys are still going out, but anything tied to the noticing pipeline itself has been dark since last Thursday. A BAE Systems spokesperson said that the company is “aware of a security incident that is isolated to the BNC system” and has taken immediate steps to address it. BAE Systems is “coordinating closely” with the courts on the response, the spokesperson said. Neither BAE nor the judiciary disclosed tachnical details of the incident, whether it was a deliberate cyber attack or a different kind of incident, or whether any data was accessed or taken. The Eastern District of Texas bankruptcy court’s own public notice adds a useful detail: BAE first told the Administrative Office about the problem late on October 9, which means the court system’s administrative leadership knew by that evening. “Late on Friday, October 9, 2026, BAE Systems, the contractor that services the Bankruptcy Noticing Center (BNC), notified the Administrative Office of a service disruption impacting BAE systems that process notices as well as the following websites: bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service website that supports CM/ECF access to address labels (the mailing matrix).” reads the notice. “Because of this disruption, the court polling and certification drop-off process that supports the delivery of electronic and paper notices has been interrupted and the BNC is unable to provide noticing services to the courts at this time.” Courts started posting disruption notices on October 13, but none of them mentioned a cybersecurity incident at that point, several framed it as a service interruption. The public acknowledgment of the word “cybersecurity” didn’t come until October 15. Summarizing, the incident started on or before October 9. The judiciary’s administrative office learned about it that day. Courts informed users of the problem on October 13, and the public announcement confirming a cybersecurity incident came on October 15. That’s six days between the contractor discovering the problem and the public announcement. During that time, bankruptcy cases across the country continued without the system that sends notices to keep courts, creditors, and lawyers informed. No one has announced when the service might be restored, suggesting the investigation is still at an early stage. This incident highlights a recurring problem: critical systems operated by contractors can fail in a single incident, disrupting services across every federal court handling a specific type of case. The public also waited nearly a week for an official statement. This is not a new pattern, but it keeps happening.

Cybersecurity researchers are sounding the alarm related to an active campaign in which unknown threat actors are abusing a compromised Microsoft 365 (M365) credential belonging to ConnectWise Cloud Backup (formerly SkyKick) to gain unauthorized access to customers' M365 environments.

Candiru spyware was delivered to devices at Al Jazeera Media Network via targeted online advertisements in a zero-click attack that required only rendering the malicious ads on the victim's device. Researchers at Citizen Labs investigating the attacks referred to this technique as AdFection, noting that their report is the first public technical confirmation of mercenary spyware delivered through targeted ads. A similar method was documented in late 2025 by Amnesty International, involving ads that infected targets with Predator spyware without them clicking anything. That infection mechanism was called Aladdin and surfaced due to a collection of marketing files and documents leaked from the Intellexa surveillance company that researchers studied and corroborated with technical details from forensic investigations.

Burger King Japan, the Japanese subsidiary of global fast-food giant Burger King, disclosed a major data breach after attackers accessed a server containing 11.18 million customer records. Founded in 1953 in Florida, Burger King is now a multinational fast-food chain with nearly 20,000 locations worldwide, including 350 in Japan. In a Thursday press release, Burger King Japan said it concluded a follow-up investigation on October 13 and apologized to customers whose data was stolen in early October and leaked online. The breached servers stored the personal information for users of the company's official smartphone app, including their names, dates of birth, gender, email addresses, phone numbers, and order history. "We identified a potential unauthorized third-party access to the system that manages member information for our official app and conducted an investigation," Burger King Japan said.
