Researchers Find New Approach to Attacking Cloud Infrastructure

www.darkreading.com/cloud/researchers-find-new-approach-to-attacking-cloud-infrastructure/d/d-id/1336327?_mc=rss_x_drr_edt_aud_dr_x_x-rss-simple Cloud APIs’ accessibility over the Internet opens a new window for adversaries to gain highly privileged access to cloud assets.. At this year’s Black Hat Europe, Gofman and Shani plan to demonstrate an alternative new approach to attacking cloud infrastructure in a talk titled “Inside Out The Cloud Has Never Been So Close.” Their methodology involves using a graph to show permission relationships between different entities,. revealing risky choke points that need to be addressed and eliminated. The outcome of this graph, they say, can be used by red and blue teams to gain deeper understanding of permission relationships in cloud environments. After explaining the connections, they’ll show how attackers can abuse features to gain privileges.

cyberstability.org/report/ [T]he Global Commission on the Stability of Cyberspace (GCSC) was convened to make recommendations for advancing cyberstability.. […] the Commission crafted eight norms designed to better ensure the stability of cyberspace and address technical concerns or gaps in previously declared norms. [T]he Commission makes six recommendations which focus on strengthening the multistakeholder model, promoting norms adoption and implementation, and ensuring that those who violate norms are held accountable.. For the members and supporters of the GCSC, however, as well as all those who support its goals, the hard work required to implement these principles, norms, and recommendations is just beginning. Begin it must, as the benefits of cyberspace will be lost if its stability is not ensured.

PureLocker: New Ransomware-as-a-Service Being Used in Targeted Attacks Against Servers

www.intezer.com/blog-purelocker-ransomware-being-used-in-targeted-attacks-against-servers/ We have found a new and undetected ransomware threat that is being used for targeted attacks against production servers of enterprises. Using code reuse analysis, we discovered this threat is closely related to the more_eggs backdoor malware, which is sold on the dark web by a veteran MaaS provider and has been used by the Cobalt Gang, FIN6, and other threat groups.. We have named this ransomware PureLocker because its written in the PureBasic programming language.. Its worth noting that the ransom note does not ask for the payment type or for the monetary amount inside of the note itself, instead instructing the victim to contact the attacker via email. The attackers use the anonymous and encrypted Proton email service.

Page Cache Attacks paper, new version at CCS 19

misc0110.net/web/files/pagecacheattacks.pdf We systematically analyze the side channel by demonstrating different hardware-agnostic local attacks, including a sandbox-bypassing high-speed covert channel, an ASLR break on Windows 10, and various information leakages that can be used for targeted extortion, spam campaigns, and more directly for UI redressing attacks.. We also show that, as with hardware cache attacks, we can attack the generation of temporary passwords on vulnerable cryptographic implementations. Our hardware-agnostic attacks can be mitigated with our proposed security patches, but the basic side channel remains exploitable via timing measurements.

TAA and other RIDL issues

mdsattacks.com/#ridl-ng On Nov 12, 2019, we (VUSec) disclose TSX Asynchronous Abort (TAA), a new speculation-based vulnerability in Intel CPUs as well as other MDS-related issues, as described in our new RIDL addendum. In reality, this is no new vulnerability. We disclosed TAA (and other issues) as part of our original RIDL submission to Intel in Sep 2018. Unfortunately, the Intel PSIRT team missed our submitted . proof-of-concept exploits (PoCs), and as a result, the original MDS mitigations released in May 2019 only partially addressed RIDL. You can read the full story below.. Addendum at


Update: New Variant of ZombieLoad enables attacks on MDS-resistant CPUs

zombieloadattack.com/ With November 14th, 2019, we present a new variant of ZombieLoad that enables the attack on CPUs that include hardware mitigations against MDS in silicon. With Variant 2 (TAA), data can still be leaked on microarchitectures like Cascade Lake where other MDS attacks like RIDL or Fallout are not possible. Furthermore, we show that the software-based mitigations in combinations with microcode updates . presented as countermeasures against MDS attacks are not sufficient..

Telegram MTProxy Servers Used to DDoS Iranian Cloud Provider

www.bleepingcomputer.com/news/security/telegram-mtproxy-servers-used-to-ddos-iranian-cloud-provider/ As Telegram continues to be banned in Iran, users in this country route their messenger communication through MTProxy servers, which make the traffic look random through encryption. This makes restricting it difficult, allowing servers to fulfill their anti-censorship purpose.. The company notes that these distributed attacks are different from what was seen before. They targeted Arvan Cloud edge servers, had no domain defined in the requests, traffic was recorded at layer two (data link) and did not use a common protocol.

Plugging the Data Leak in Manufacturing

threatpost.com/plugging-data-leak-manufacturing/150132/ Increasingly, manufacturers are deploying IoT technology to better facilitate automation and help increase productivity. Car manufacturers, railways and even companies in the food and beverage space are using families of networked sensors, actuators and other devices to collect production data and feed it to the cloud to gather further insight into their systems efficiency.. However, IIoT-generated data calibrations, measurements and other parameters still need to be stored, managed and shared securely to provide a company with maximum impact. Failing to do so could have a drastic outcome and result in service disruptions, the loss of intellectual property and data leaks.
