Hackers Flood NPM with Bogus Packages Causing a DoS Attack
2023-04-10 12:45

Threat actors are flooding the npm open source package repository with bogus packages that briefly even resulted in a denial-of-service attack. "The threat actors create malicious websites and publish empty packages with links to those malicious websites, taking advantage of open-source ecosystems' good reputation on search engines," Checkmarx's Jossef Harush Kadouri said in a report published last week.

Flood of malicious packages results in NPM registry DoS
2023-04-05 11:49

Attackers are exploiting the good reputation and "Openness" of the popular public JavaScript software registry NPM to deliver malware and scams, but are also simultaneously and inadvertently launching DoS attacks against the service. Malicious package on NPM pointing to a site serving malware.

New Study Uncovers Text-to-SQL Model Vulnerabilities Allowing Data Theft and DoS Attacks
2023-01-09 13:37

A group of academics has demonstrated novel attacks that leverage Text-to-SQL models to produce malicious code that could enable adversaries to glean sensitive information and stage denial-of-service attacks. The findings, which were validated against two commercial solutions BAIDU-UNIT and AI2sql, mark the first empirical instance where natural language processing models have been exploited as an attack vector in the wild.

Ethernet VLAN Stacking flaws let hackers launch DoS, MiTM attacks
2022-09-28 15:05

Four vulnerabilities in the widely adopted 'Stacked VLAN' Ethernet feature allows attackers to perform denial-of-service or man-in-the-middle attacks against network targets using custom-crafted packets. Stacked VLANs, also known as VLAN Stacking, is a feature in modern routers and switches that allows companies to encapsulate multiple VLAN IDs into a single VLAN connection shared with an upstream provider.

Russian Hackers Tricked Ukrainians with Fake "DoS Android Apps to Target Russia"
2022-07-21 03:06

Russian threat actors capitalized on the ongoing conflict against Ukraine to distribute Android malware camouflaged as an app for pro-Ukrainian hacktivists to launch distributed denial-of-service attacks against Russian sites. "The apps were not distributed through the Google Play Store, but hosted on a domain controlled by the actor and disseminated via links on third party messaging services."

OpenSSL patches infinite-loop DoS bug in certificate verification
2022-03-18 19:59

Amusingly, if we're allowed to say that, the bug only gets triggered if a program decides to do the right thing when making or accepting a secure connection, and verifies the cryptographic certificate supplied by the other end. The OpenSSL implementation of the Tonelli-Shanks algorithm had a bug problem that was unlikely to show up in normal use, but could be triggered on purpose by feeding in data that would force the code to misbehave.

Apple Releases iPhone and iPad Updates to Patch HomeKit DoS Vulnerability
2022-01-12 20:58

Apple on Wednesday rolled out software updates for iOS and iPadOS to remediate a persistent denial-of-service issue affecting the HomeKit smart home framework that could be potentially exploited to launch ransomware-like attacks targeting the devices. The iPhone maker, in its release notes for iOS and iPadOS 15.2.1, termed it as a "Resource exhaustion issue" that could be triggered when processing a maliciously crafted HomeKit accessory name, adding it addressed the bug with improved validation.

URL Parsing Bugs Allow DoS, RCE, Spoofing & More
2022-01-10 17:55

Eight different security vulnerabilities arising from inconsistencies among 16 different URL parsing libraries could allow denial-of-service conditions, information leaks and remote code execution in various web applications, researchers are warning. Multiple Parsers in Use: Whether by design or an oversight, developers sometimes use more than one URL parsing library in projects.

Critical Apache HTTPD Server Bugs Could Lead to RCE, DoS
2021-12-22 17:59

Don't duck at the latest mention of Apache: Two critical bugs in its HTTP web server - HTTPD - need to be patched pronto, lest they lead to attackers triggering denial of service or bypassing your security policies. Both vulnerabilities are found in Apache HTTP Server 2.4.51 and earlier.

Third Log4J Bug Can Trigger DoS; Apache Issues Patch
2021-12-20 16:01

No, you're not seeing triple: On Friday, Apache released yet another patch - version 2.17 - for yet another flaw in the ubiquitous log4j logging library, this time for a DoS bug. The latest bug isn't a variant of the Log4Shell remote-code execution bug that's plagued IT teams since Dec. 10, coming under active attack worldwide within hours of its public disclosure, spawning even nastier mutations and leading to the potential for denial-of-service in Apache's initial patch.
