Worldwide attacks on SS7/SIGTRAN networkP1Security
Publication performed by Alexandre De Oliveira and Pierre-Olivier Vauboin during Hackito Ergo Sum 2014
Mobile telecommunication networks are complex and provide a wide range of services, making them a tempting target for fraudsters and for intelligence agencies. Moreover, the architecture, equipment and protocols used on these networks were never designed with security in mind, availability being the first concern. Today, even though some telecom operators are investing money into securing their network, events confirm that for most of them maturity in term of security is yet to come, as recently shown with the example of massive traffic interception on compromised SCCP and GRX providers like Belgacom’s BICS. Here we present the most typical and legitimate telecom callflows from making a mobile phone call to sending a SMS. Then we describe the protocol layers involved and how to abuse them, which fields can be manipulated in order to attack both the operator infrastructure and its subscribers. Finally, we show a real life example of scan performed from an international SS7 interconnection and practical attacks on subscribers such as spam, spoofed SMS and user location tracking.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
4. Encryption & Authentication used in IEEE
802.11 Environment:
Wired Equivalent Privacy (WEP) – WEP uses RC4 encryption algorithm which has
several weaknesses. WEP relies on secret key “shared” between a wireless device
and the AP
Wi-Fi Protected Access (WPA) – WPA protocol implements majority of IEE 802.11i standard
requirements. WPA makes use of Temporal Key Integrity Protocol (TKIP) instead of RC4 used
in its predecessor WEP. To offer greater security
WPA Personal – Commonly referred as WPA – Pre shared key (PSK). The clients authenticate
with the AP’s using the 256 bit keys.
WPA Enterprise – Mainly designed for Enterprise networks and requires authentication using
RADIUS server. Extensible Authentication Protocol (EAP) is used for authentication, which
comes in different flavors (EAP-TLS, EAP-TTLS).
RADIUS protocol inherently only allows for password based authentication i.e. the password
is sent as MD5 Hash or response to a challenge, (EAP) is an authentication framework
included in Windows Client and Windows Server operating systems
5. Wi-Fi authentication mode

8. Wi-Fi vulnerability assessment checklist
• Vulnerability assessments can help you find and fix WLAN
weaknesses before attackers take advantage of them
Wireless Sniffing
• Wireless Card can be only on one channel at a time
• Can not sniff on all channels and band at the same time
• Wireless card needs to be capable of operate a/b/g/n/h ?
For each discovered 802.11 access point, document:
Media Access Control (MAC) address (BSSID)
Extended service set identifier (ESSID)
Channel Number
Average/Peak signal-to-noise ratio (SNR)
Beaconed security parameters (i.e., WEP, Wpa, wpa2 security)
13. Wi-Fi Security Assessment
Wi-Fi authentication process using centralized authentication server
Client Request Connection
