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

With browser makers steadily clamping down on third-party tracking, advertising technology companies are increasingly embracing a DNS technique to evade such defenses, thereby posing a threat to web security and privacy. Called  CNAME Cloaking , the practice of blurring the distinction between first-party and third-party cookies not only results in leaking sensitive private information without users' knowledge and consent but also "increases [the] web security threat surface," said a group of researchers Yana Dimova, Gunes Acar, Lukasz Olejnik, Wouter Joosen, and Tom Van Goethem in a new study. "This tracking scheme takes advantage of a CNAME record on a subdomain such that it is same-site to the including web site," the researchers  said  in the paper. "As such, defenses that block third-party cookies are rendered ineffective." The findings are expected to be presented in July at the 21st Privacy Enhancing Technologies Symposium (PETS 2021). Rise

If forecasters are right, over the course of today, consumers will spend  $13.7 billion . Just about every click, sale, and engagement will be captured by a CRM platform. Inventory applications will trigger automated re-orders; communication tools will send automated email and text messages confirming sales and sharing shipping information.  SaaS applications supporting retail efforts will host nearly all of this behind-the-scenes activity. While retailers are rightfully focused on sales during this time of year, they need to ensure that the SaaS apps supporting their business operations are secure. No one wants a repeat of one of the biggest retail cyber-snafus in history, like when one U.S.-based national retailer had 40 million credit card records stolen.  The attack surface is vast and retailers must remain vigilant in protecting their entire SaaS app stack. For example, many often use multiple instances of the same application. They may use a different Salesforce tenant for eve

Just a year after Mirai —biggest IoT-based malware that caused vast Internet outages by launching massive DDoS attacks—completed its first anniversary, security researchers are now warning of a brand new rapidly growing IoT botnet. Dubbed ' IoT_reaper ,' first spotted in September by researchers at firm Qihoo 360, the new malware no longer depends on cracking weak passwords; instead, it exploits vulnerabilities in various IoT devices and enslaves them into a botnet network. IoT_reaper malware currently includes exploits for nine previously disclosed vulnerabilities in IoT devices from following manufactures: Dlink (routers) Netgear (routers) Linksys (routers) Goahead (cameras) JAWS (cameras) AVTECH (cameras) Vacron (NVR) Researchers believe IoT_reaper malware has already infected nearly two million devices and growing continuously at an extraordinary rate of 10,000 new devices per day. This is extremely worrying because it took only 100,000 infected devices

Patches Released for BIND Denial-of-service Vulnerability There's a new vulnerability in the popular BIND name server software that is causing various versions of the application to crash unexpectedly after logging a certain kind of error. The Internet Systems Consortium (ISC), an organization that maintains several software products critical for Internet infrastructure, has released a patch for an actively exploited denial-of-service vulnerability in the widely used BIND DNS server. The internet Systems Consortium (ISC) have described the problem as follows: An as-yet unidentified network event caused BIND 9 resolvers to cache an invalid record, subsequent queries for which could crash the resolvers with an assertion failure... Affected servers crashed after logging an error in query.c with the following message: "INSIST(! dns_rdataset_isassociated(sigrdataset)) More details are available in their advisory . As of this posting, ISC had not revealed the underlying problem,
