I know what you ordered last summer @ Winterkongress 2024
Dennis and I already published blog posts about our research project dealing with vulnerabilities in parcel tracking implementations at DHL and DPD. At the Winterkongress (winter congress) in Winterthur, Switzerland, we had the great opportunity to give a talk about the matter. The talk was recorded and can be watched here.
DigiGes held the Winterkongress, which took place in Winterthur on 01.03. till 02.03.2024. The main topics are ethics, threats, and opportunities of IT. This year, many talks looked at AI in some way. Continue reading “I know what you ordered last summer @ Winterkongress 2024”

This blog post is the continuation of our parcel research. We already reported about how we broke parcel tracking at DHL and the disclosure process of the identified problems. As DHL is not the only parcel service in Germany, we also investigated the other available parcel services. In this blog post, we want to talk about DPD, also called Geopost, which belongs to the French Post Office.

At Troopers 2023, we gave a talk on how to attack DHL parcel tracking information based on OSINT. Since we previously had an exemplary disclosure process about this attack with DHL, Mr. Kiehne (from DHL) joined us to provide interesting background information and insights on how they addressed our findings.

The Reason
I recently stumbled upon a strange behavior in my Firefox: I visited an HTTPS-enabled website that I had visited before and saw that my Firefox connected insecurely via HTTP. I found that strange because nowadays, most websites set the HSTS header, which is supposed to force the browser to connect via HTTPS. I checked whether this website set the HSTS header – and it did. This means my Firefox was ignoring/forgetting about the HSTS header right after my visit. Continue reading “Analysis of HSTS Caches of Different Browsers”

The Situation
Last year, the CISO of a customer sent me a laptop for analysis. The reason was that he feared the company could have been victim of industrial espionage. Starting in spring 2020, the IT help desk got several employee laptops with full hard drives, caused by a huge amount of audio recordings. The audio files contained recordings even of highly sensitive telephone conferences. An automated scan on all employee computers for such audio recordings showed that about 300 devices were affected.

I am glad to announce the release of the ERNW whitepaper 71 containing information about quarantine file formats of different AV software vendors. It is available here.
Anti-Virus Software
I took quarantine files from real-life incidents and created some in a lab environment. Afterwards I tried to identify metadata, like timestamps, path names, malware names, and the actual malicious file in the quarantine files. One goal was to use this information to support our incident analyses: Using the results, we can now easily create timelines showing information about quarantined files, extract the detected malware, and sometimes even find information about processes that created the malicious files.
