Researchers have discovered a new side-channel that they say can be reliably exploited to leak information from web browsers that could then be leveraged to track users even when JavaScript is completely disabled. "This is a side-channel attack which doesn't require any JavaScript to run," the researchers said. "This means script blockers cannot stop it. The attacks work even if you strip out all of the fun parts of the web browsing experience. This makes it very difficult to prevent without modifying deep parts of the operating system." In avoiding JavaScript, the side-channel attacks are also architecturally agnostic, resulting in microarchitectural website fingerprinting attacks that work across hardware platforms, including Intel Core, AMD Ryzen, Samsung Exynos 2100, and Apple M1 CPUs — making it the first known side-channel attack on the iPhone maker's new ARM-based chipsets. The  findings , which come from a group of academics from the Ben-Gurion U...

Firewall and distributed denial-of-service (DDoS) attack prevention mechanisms in Cloudflare can be circumvented by exploiting gaps in cross-tenant security controls, defeating the very purpose of these safeguards, it has emerged. "Attackers can utilize their own Cloudflare accounts to abuse the per-design trust-relationship between Cloudflare and the customers' websites, rendering the protection mechanism ineffective," Certitude researcher Stefan Proksch  said  in a report published last week. The problem, per the Austrian consulting firm, is the result of shared infrastructure available to all tenants within Cloudflare, regardless of whether they are legitimate or otherwise, thereby making it easy for malicious actors to abuse the implicit trust associated with the service and defeat the guardrails. The first issue stems from opting for a shared Cloudflare certificate to authenticate HTTP(S) requests between the service's reverse proxies and the customer's o...

A highly critical vulnerability has been uncovered in the GNU C Library (glibc) , a key component of most Linux distributions, that leaves nearly all Linux machines, thousands of apps and electronic devices vulnerable to hackers that can take full control over them. Just clicking on a link or connecting to a server can result in remote code execution (RCE), allowing hackers to steal credentials, spy on users, seize control of computers, and many more. The vulnerability is similar to the last year's  GHOST vulnerability (CVE-2015-0235) that left countless machines vulnerable to remote code execution (RCE) attacks , representing a major Internet threat. GNU C Library (glibc) is a collection of open source code that powers thousands of standalone apps and most Linux distributions, including those distributed to routers and other types of hardware. The recent flaw, which is indexed as CVE-2015-7547 , is a stack-based buffer overflow vulnerability in glibc's D...

The threat actors behind the CatDDoS malware botnet have exploited over 80 known security flaws in various software over the past three months to infiltrate vulnerable devices and co-opt them into a botnet for conducting distributed denial-of-service (DDoS) attacks. "CatDDoS-related gangs' samples have used a large number of known vulnerabilities to deliver samples," the QiAnXin XLab team  said . "Additionally, the maximum number of targets has been observed to exceed 300+ per day." The flaws impact routers, networking gear, and other devices from vendors such as Apache (ActiveMQ, Hadoop, Log4j, and RocketMQ), Cacti, Cisco, D-Link, DrayTek, FreePBX, GitLab, Gocloud, Huawei, Jenkins, Linksys, Metabase, NETGEAR, Realtek, Seagate, SonicWall, Tenda, TOTOLINK, TP-Link, ZTE, and Zyxel, among others. CatDDoS was previously documented by  QiAnXin  and  NSFOCUS  in late 2023, describing it as a  Mirai botnet variant  capable of performing DDoS attacks using...

Distributed Denial of Service attacks have increased in scale, intensity and frequency. The wide range of motives for these attacks political , criminal, or social makes every merchant or organization with an online presence a potential target. Over the weekend Incapsula mitigated a unique DDoS attack against a large gaming website, in which they have discovered a DDoS attack using thousands of legitimate WordPress blogs without the need for them to be compromised. Incapsula released the list of approximately 2,500 WordPress sites from where the attack was originated, including some very large sites like Trendmicro.com, Gizmodo.it and Zendesk.com . In a recent report , we posted about another method for DDoS attacks using DNS amplification , where a DNS request is made to an open DNS resolver with the source IP address forged so that it is the IP address of the targeted site to which the response is thus sent, but this new method uses HTTP rather tha...
