ATHENE Distinguished Lecture with Anat Bremler-Barr| hybrid

Prof. Anat Bremler-Barr from Blavatnik School of Computer Science, Tel-Aviv University is our guest at the ATHENE Distinguished Lecture Series. She talks about: "Cloud Auto-scaling Mechanisms Under DDoS Attacks: Yo-Yo Attack and Tandem Attack".

At the ATHENE Distinguished Lectures, we invite established national and inter­national cybersecurity experts to give us insights into their latest research findings.
The lectures are mostly held hybrid (on-site at Fraunhofer SIT in Darmstadt), so that there is also the possibility to meet and exchange with the key players in cybersecurity in person after the lecture with tasty snacks and drinks.
The language of the lecture is English.
ATHENE Distinguished Lecture Series is organized by Prof. Haya Shulman, ATHENE | Goethe University Frankfurt | Fraunhofer SIT.

On June 22, Anat Bremler-Barr from Blavatnik School of Computer Science, Tel-Aviv Universitywill be our guest.

Title: Cloud Auto-scaling Mechanisms Under DDoS Attacks: Yo-Yo Attack and Tandem Attack

It is a common belief that Auto-scaling mechanisms serve as a mitigation for Distributed Denial of Service (DDoS) attacks on cloud computing infrastructures by dynamically adding machines to cope with the additional load. Intuitively, such attacks are mostly associated with Economic Denial of Sustainability (EDoS) derived from paying for the extra resources required to process the malicious incoming traffic.

Contrary to this belief, we present and analyze the Yo-Yo attack, a new attack against the auto-scaling mechanism that can cause significant performance degradation in addition to economic damage. We demonstrate the attack on Amazon EC2, Kubernetes, and serverless architecture. We then present and analyze Tandem Attack, a new attack on Microservices architecture. In this attack, the attacker exploits the tandem behavior of services with different auto-scaling mechanisms, causing both economic and performance damage.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
