  • ConnectWise Suspends Cloud Backup After Attackers Compromise Microsoft 365 Tenants

    ConnectWise Suspends Cloud Backup After Attackers Compromise Microsoft 365 Tenants

    ConnectWise has disabled seven application identities and suspended its Cloud Backup service after unknown attackers gained unauthorized access to the credentials and compromised Microsoft 365 tenants. The company took action on October 17, 2026, by revoking certificates used for affected application connections across all users. ConnectWise noted that while scheduled backups are not running and restoration capabilities are unavailable, existing backup archives remain encrypted and preserved with no evidence of breach or unauthorized access.

    The company identified the security incident on October 14 through its monitoring systems. Attackers used the stolen application credentials to authenticate as ConnectWise applications and potentially access customer Microsoft 365 environments, including mailboxes, SharePoint documents, Teams messages, and directory information. Security researchers at Huntress confirmed malicious activity through October 15 and identified a second wave of targeted attempts against 16 tenants in policy, national security, trade, and critical mineral sectors, though these efforts were unsuccessful.

  • New drug reverses severe fatty liver disease by repairing the gut

    New drug reverses severe fatty liver disease by repairing the gut

    Researchers at Michigan Medicine have developed an experimental drug called DT-109 that reversed severe fatty liver disease in animal studies by targeting the gut rather than the liver directly. The compound works by reducing harmful gut bacteria, strengthening the intestinal lining, and preventing inflammatory substances from entering the liver. The findings, published in The Journal of Clinical Investigation, demonstrate a new approach to treating metabolic dysfunction-associated steatohepatitis (MASH), a serious form of fatty liver disease affecting approximately 7% of the global population.

    MASH causes excess fat accumulation in the liver, leading to inflammation and cellular damage that can progress to cirrhosis, liver cancer, and liver failure. The research revealed that DT-109 interrupts a damaging cycle by reducing levels of harmful bacteria that produce ammonia, which weakens the gut’s protective barrier and allows toxins to reach the liver. While results in mice and nonhuman primates were encouraging, the drug remains experimental and has not yet been tested in humans. Researchers plan further evaluation with the goal of advancing DT-109 toward clinical trials to determine its safety and effectiveness in patients.

  • MALFEX npm Package ‘imgdecode’ Hides Shellcode Loader in Windows Native Addon

    MALFEX npm Package ‘imgdecode’ Hides Shellcode Loader in Windows Native Addon

    Researchers have identified a malicious npm package called “imgdecode” as part of a supply chain attack campaign named MALFEX. Uploaded on September 30, 2026, the package contains a Windows dynamic-link library that downloads encrypted shellcode from GitHub, decrypts it, and injects it into a new process when loaded. The package has been downloaded 979 times and remains available on npm. The MALFEX campaign, active since August 2023, has distributed eight malicious packages across five publisher accounts designed to compromise Windows systems through various infection methods.

    The threat actor behind MALFEX has demonstrated responsiveness to public disclosures and npm removals by quickly publishing replacement packages. The malware performs anti-analysis checks and harvests sensitive files, cryptocurrency wallet information, and data from web browsers and gaming applications. It also establishes command-and-control connections enabling shell execution, file transfers, and system monitoring. Developers who installed these packages should immediately isolate affected Windows systems, check for persistence mechanisms, rotate credentials, and move cryptocurrency to new wallets if seed phrases were compromised.

  • Hackers breach Microsoft 365 tenants via ConnectWise supply-chain attack

    Hackers breach Microsoft 365 tenants via ConnectWise supply-chain attack

    ConnectWise has suspended access to its Cloud Backup service following a security breach involving unauthorized access to application identities that compromised Microsoft 365 tenants. The attack began around October 15 from a single IP address, with Huntress identifying at least 162 compromised tenants. Microsoft confirmed the malicious activity on the same date. The attacker used the backup service’s existing permissions to access customer data, including emails, files, and Teams chats. Since the attack involved automated scripts rather than user logins, security measures like multi-factor authentication proved ineffective.

    Multiple cybersecurity firms documented the breach’s scope and methods. Todyl researchers found that attackers directly authenticated to Microsoft 365 using the backup application’s credentials, while Huntress observed persistence attempts on nearly 50 monitored tenants where attackers assigned themselves administrative roles. Microsoft characterized the incident as an active supply-chain attack. ConnectWise stated that stored backup data had not been compromised and would remain accessible once services resume, though the company provided no timeline for restoration. Administrators have been advised to review application credentials, sign-in activities, and remove unauthorized additions since October 13.

  • Employees using personal ChatGPT at work? Here’s what IT admins need to do

    Employees using personal ChatGPT at work? Here’s what IT admins need to do

    Information technology administrators face challenges when employees use personal ChatGPT accounts on work devices, even when organizations provide corporate subscriptions. Security teams must identify which employee and account are involved, determine what sensitive information may have been submitted to the service, and understand why the employee bypassed the approved corporate tool. Common reasons include expired sessions, slow authentication processes, or employee confusion about policies. Administrators should then assess the severity of any data exposure and determine appropriate next steps based on what information was actually shared.

    To prevent future incidents, IT leaders should ensure corporate ChatGPT access functions reliably so employees have no reason to use personal accounts. They should also review and clarify data submission policies. Some security tools can block prompts containing specific sensitive data patterns before information leaves the device, stopping submissions automatically and notifying employees of the restriction. Documentation of incidents should accurately record only confirmed facts about what occurred and which controls either failed or successfully prevented data exposure, without speculation about whether data entered model training or became public.

  • Hackers Use Compromised ConnectWise Credential to Sign In to 173 Microsoft 365 Tenants

    Hackers Use Compromised ConnectWise Credential to Sign In to 173 Microsoft 365 Tenants

    Cybersecurity researchers have identified an active attack campaign in which unknown threat actors are exploiting a compromised Microsoft 365 credential from ConnectWise Cloud Backup to gain unauthorized access to customer environments. Security firm Huntress confirmed unauthorized sign-ins across 173 partner and customer tenants using the stolen credential. Because ConnectWise Cloud Backup requires broad permissions to access mailboxes, OneDrive, SharePoint, Teams, and directory data, attackers with the compromised credential can access sensitive information across affected organizations. The attacker used a specific IP address to obtain tokens and systematically moved through tenants in a scripted manner between October 15 and early morning hours UTC.

    In response, ConnectWise has suspended Cloud Backup application access pending further investigation. Security researchers recommend that organizations immediately disable the application, enable Microsoft Graph activity logging, and audit for any unauthorized credential additions or suspicious directory role assignments since October 13. Experts caution that some types of unauthorized access may leave no audit trail, making immediate action preferable to waiting for evidence of data compromise. ConnectWise stated it found no evidence that customer backup data was compromised, though the full impact depends on permissions configured in each affected tenant.

  • US measles cases grow by 8% in 1 week for a total of 4,410 cases

    US measles cases grow by 8% in 1 week for a total of 4,410 cases

    Measles cases in the United States have reached 4,410 this year, representing an 8% increase over the past week alone. This single-week surge of 330 cases already exceeds the entire 2024 measles total of 285 cases. The outbreak has spawned 42 new outbreaks across the country, with 96% of confirmed cases occurring in people who were unvaccinated or had unknown vaccination status. Public health experts believe the actual number of infections is substantially higher than reported figures due to underreporting of milder cases treated at home rather than in medical settings.

    Pennsylvania has been particularly hard hit, reporting 1,260 confirmed cases and six deaths. Health officials estimate the true number of infections in the state could exceed 6,000 based on historical measles mortality rates. The CDC has deployed epidemiologists to help contain multiple outbreaks in Pennsylvania counties. Other states experiencing significant measles activity include Kentucky with 170 cases, New York with 126 cases and a declared statewide health emergency, and Ohio with 252 cases.

  • Critical BlockStrap flaw lets hackers run code on Magento servers

    Critical BlockStrap flaw lets hackers run code on Magento servers

    A maximum-severity vulnerability affecting Magento and Adobe Commerce platforms could allow hackers to execute malicious code on store servers. Known as BlockStrap and identified as CVE-2026-103849, the flaw impacts September versions of Adobe Commerce and Magento Open Source through 2.4.9, as well as Adobe Commerce B2B through 1.5.3. Security researchers at Sansec have identified four potential attack paths within 24 hours, though active exploitation has not yet been documented.

    Sansec researchers contend that Adobe’s priority rating of the vulnerability does not adequately reflect its severity and urgency, warning that attackers using artificial intelligence tools could develop working exploits relatively quickly. The company notes that administrators must apply both the latest patches and previous security fixes to fully address the risk, as BlockStrap and an earlier flaw called StyleSmuggler require separate corrections. Sansec expects mass attack campaigns to begin soon and plans to provide updates as attacks emerge.

    Kenya Confirms Third Ebola Case as DRC Outbreak Expands to Eighth Province with Over 9,200 Infections

    Kenya has confirmed a third Ebola case, involving a 65-year-old woman who is a close relative of the country’s first two infected individuals. The woman entered quarantine before symptoms appeared. Meanwhile, the Democratic Republic of Congo’s outbreak has expanded to an eighth province, North Ubangi, where two cases have been detected, though officials have not yet made an official announcement. The virus has now affected multiple provinces across the DRC, with Ituri province reporting the highest number of cases. According to the CDC, the outbreak has infected over 9,200 people and caused more than 4,400 deaths.

    The situation has been particularly severe among schoolchildren in the DRC, with 10 students dying from the Bundibugyo Ebola virus despite schools reopening only recently. Twenty-five confirmed cases have been identified among schoolchildren in Ituri province, with seven survivors still receiving treatment. Humanitarian organizations report that approximately seven children have died daily from Ebola since the outbreak began in May, totaling 961 child deaths. Currently, no vaccine or specific treatment exists for the Bundibugyo virus, but researchers in Uganda have initiated a phase 1 clinical trial to test a candidate vaccine’s safety and immune response effectiveness.
