Context #

During a TCP+TLS connection, the server must supply a certificate chain so that the client can authenticate it. That chain can be long and complex, and transferring all the necessary x509 certificates costs packet round trips at connection time. For mail servers, an alternative is seeing growing use: DANE. Built on DNS and authenticated by DNSSEC, DANE binds TLS certificates to services on domain names. The DNS infrastructure delivers that data to clients efficiently and keeps certificates cached for later reuse.

RDAP: Frontier between protocol specification and implementation

Thu, 28 Sep 2023 00:00:00 +0000

DNS stands for Domain Name System, and domain names are what our research is about. They are an integral part of our daily lives. You’ve already come across domain names such as “google.com”, “univ-grenoble-alpes.fr”, or “amazon.com”. But what about “support-tech-apple.com”, “bank-of-america-help.com” or even “paypall.com”? All of these are malicious domain names, built to mislead users into a phishing site.

By studying domain names, we can improve Internet security. One of our team’s earlier projects, COMAR, distinguishes compromised domain names from malicious ones. For example, if the domain name “univ-grenoble-alpes.fr” hosts malicious content, should it be taken down? And what about paypall.com? COMAR separates the compromised domain — here univ-grenoble-alpes.fr — whose administrator should be notified, from paypall.com, where the right response is to act against the domain name itself.

Internships in Cybersecurity 2022/2023 (M1/M2 students)

Fri, 21 Oct 2022 00:00:00 +0000

The Drakkar research group at LIG Lab is looking for M1/M2 interns. Some of the topics addressed by our team are strongly related to a wide range of practical aspects of cybersecurity. They would allow you to work on subjects such as:

Application of machine learning/artificial intelligence methods to cybersecurity problems
Phishing attacks (e.g., discovering malicious domains, typosquatting, phishing attacks against financial institutions, etc.)
Denial-of-Service attacks and defenses (e.g., prevention, discovering protocols and networks enabling attacks)
Internet-wide vulnerability scanning (e.g., building tools to search for vulnerabilities, vulnerability notifications)
Cybercrime (e.g., bulletproof hosting providers)
IoT Honeypots, sandboxes, botnets, malicious infrastructures
Bypassing security measures, creating effective countermeasures and secure systems
Network security (e.g., BGP, DNS)
Measurements of the deployment of secure protocols (e.g., DNSSEC, DMARC)
Malware reverse engineering

If you are motivated and have a background in any of the topics listed above or other areas of cybersecurity and you’d like to propose your own subject, please send your CV to Maciej Korczynski [maciej.korczynski at univ-grenoble-alpes.fr]. Solid systems and programming skills are a big plus, but not required.

Internships in Cybersecurity 2021/2022 (M1/M2 students)

Fri, 29 Oct 2021 00:00:00 +0000

The Drakkar research group at LIG Lab is looking for M1/M2 interns. Some of the topics addressed by our team are strongly related to empirical aspects of cybersecurity and would allow you to work on subjects such as:

Phishing attacks (e.g.: discovering malicious domains, typosquatting, phishing attacks against financial institutions, etc.)
Denial-of-Service attacks and defenses (e.g.: prevention, discovering protocols and networks enabling attacks)
Internet-wide vulnerability scanning (e.g.: building tools to search for vulnerabilities, vulnerability notifications)
Cybercrime (e.g.: bulletproof hosting providers)
IoT Honeypots

If you are motivated and have a background in any of the topics listed above, or other areas of cybersecurity and you’d like to propose your own subject, please contact Maciej Korczynski [maciej.korczynski at univ-grenoble-alpes.fr]. We can meet to discuss and potentially define an internship project. International students are encouraged to apply. You may also be able to go on to a PhD in the Drakkar team after your internship, or find a job at one of the security organizations we work closely with.

Dynamic compression rate over TCP connections

Compression is a well-known technique for increasing the available bandwidth on slow networks.

While working on the implementation of a Network File System, we have designed a preliminary algorithm that modulates the compression level given the available network bandwidth:

Internships in Cybersecurity 2019/2020

Mon, 16 Dec 2019 00:00:00 +0000

Denial-of-Service attacks and defenses (e.g.: prevention, discovering protocols and networks enabling attacks)
Internet-wide vulnerability scanning (e.g.: building tools to search for vulnerabilities, vulnerability notifications)
Phishing attacks (e.g.: discovering malicious domains, typo squatting, phishing attacks against financial institutions, etc.)
Economics of cybersecurity (e.g. why attackers tend to register malicious domains rather than compromising vulnerable websites)
Cybercrime (e.g.: bulletproof hosting providers)

If you are motivated and have a background in any of the topics listed above, or other areas of cybersecurity and you’d like to propose your own subject, please contact Maciej Korczyński [maciej.korczynski at univ-grenoble-alpes.fr], send your CV and explain your motivation. We can meet to discuss and potentially define an internship project. International students are encouraged to apply. A doctoral position may be available at the end of the internship, so that the intern can carry the work on as a PhD student.
