Berlin Refuses to Pay Hackers Who Stole Data From the City's State Network

Berlin Refuses to Pay Hackers Who Stole Data From the City's State Network

Aug 28, 2026 Data Breach / Ransomware
Berlin's state government has confirmed that it is the target of an extortion attempt following the August compromise of the city's state administrative network, and said it will not meet the extortionists' demands. The same statement disclosed that forensic work had found further data outflows in the portfolio of the Senate Department for Mobility, Transport, Climate Protection and Environment, with the exfiltration dated between August 7 and August 12, 2026. Scope and content are still being examined, and the Senate Chancellery said personal or other non-public data cannot be excluded from what was taken. The department first reported an outflow on August 7, the Senate Chancellery said in response to questions, seven days before it was cut off from the network on August 14. Berlin has published no figure for how much left the network. The only itemized account in circulation is the attackers' own, a leak-site post indexed on August 28 that claims 5.79 terabyt...
Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

Aug 28, 2026 Vulnerability / Blockchain
Cosmos Labs has warned that a critical balance-handling flaw in the shared Cosmos EVM module was exploited to drain funds from six blockchains between August 20 and August 25, 2026. The vulnerability, designated GHSA-7g4w-cg88-2cq2 , is rated Critical by Cosmos Labs and was published without a CVE identifier, a weakness classification, or a CVSS score. Affected versions are < 0.6.2 and >= 0.7.0 < 0.7.2 , and the fix shipped in v0.6.2 and v0.7.2 on August 19. Chain operators are told to upgrade to one of those releases or later, a change that is state-breaking and requires a coordinated network upgrade. Operators who cannot upgrade immediately are told to halt the chain rather than attempt a coordinated governance upgrade. In a post-mortem published August 28 , Cosmos Labs said the flaw was reported through its bug bounty program on April 25 and was assessed at the time as posing no risk to funds on live networks. "We were unable to reproduce the vulnerability ...
Attackers Chain Two PaperCut Flaws to Execute Code Without Authentication

Attackers Chain Two PaperCut Flaws to Execute Code Without Authentication

Aug 28, 2026 Vulnerability / Web Security
Malicious actors are exploiting a newly patched security flaw in PaperCut NG and MF to execute arbitrary code on susceptible instances, as the company released a fresh emergency fix with additional hardening. "This vulnerability gives an unauthenticated attacker remote control over PaperCut's trusted configuration, which could be used to execute arbitrary Java code inside the application's process," Huntress researchers John Hammond and Andrew Brandt said . Specifically, an attacker can leverage an unauthenticated request to make changes to the server configuration and ultimately achieve code execution. Huntress has explained the flaw as follows - In unpatched versions of PaperCut NG and PaperCut MF,  a specifically crafted request can refer to one page that is rendered for the response, and another page that owns the component or action being executed. PaperCut's authorization check could trust the rendered page and miss the permissions required by the...

Android 17 Adds OS-Wide ECH to Hide Website Visits From Network Providers

Android 17 Adds OS-Wide ECH to Hide Website Visits From Network Providers

Aug 28, 2026 Cellular Security / Encryption
Google on Thursday announced new network security protections in Android 17 to bolster connection privacy, address cellular vulnerabilities, and safeguard the privacy of users' home networks. Topping the list is support for Encrypted Client Hello ( ECH ), a privacy standard that prevents networks from eavesdropping on which websites a user is visiting. "This new privacy standard works in tandem with private DNS to obscure the domain names you visit, hiding metadata that can be used to profile you," Google's Bram Bonné and Shuaibo Huang said . "By encrypting the destination website name from the very start, ECH helps ensure that, for supported websites and apps, network providers and network snoopers can no longer easily see which websites or apps you are accessing."
ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

Aug 28, 2026 Vulnerability / Cyber Espionage
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical security flaw impacting ownCloud to its Known Exploited Vulnerabilities ( KEV ) catalog following reports that a Chinese-speaking threat actor weaponized the vulnerability to target a nuclear research body in the Philippines. The vulnerability, tracked as CVE-2023-49105 (CVSS score: 9.8), is a case of WebDAV API authentication bypass that could allow an attacker to access, modify or delete any file without authentication if the username of the victim is known and the victim has no signing-key configured, which is the default configuration. Disclosed by ownCloud in November 2023, the issue impacts "core" versions from 10.6.0 through 10.13.0. It was fixed in version 10.13.1. CISA's addition of the flaw to the KEV catalog comes a couple of days after Hunt.io said it identified an open directory on the host "31.58.209[.]241," which staged custom Python scripts, o...
