SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell Secureworks Counter Threat Unit℠ Threat Intelligence
SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell SecureWorks Counter Threat Unit℠ Threat Intelligence Presented at Black Hat Europe – March 14, 2012. Introduction Secure Sockets Layer (SSL) [1] and its successor Transport Layer Security (TLS) [2] have become key components of the modern Internet. The privacy, integrity, and authenticity [3] [4] provided by these protocols are critical to allowing sensitive communications to occur. Without these systems, e- commerce, online banking, and business-to-business exchange of information would likely be far less frequent. Threat actors have also recognized the benefits of transport security, and they are increasingly turning to SSL to hide their activities. Advanced Persistent Threat (APT) attackers [5], botnets [6], and even commodity web attacks can leverage SSL encryption to evade detection. To counter these tactics, organizations are increasingly deploying security controls that intercept end- to-end encrypted channels. Web proxies, data loss prevention (DLP) systems, specialized threat detection solutions, and network intrusion prevention systems (NIPS) offer functionality to intercept, inspect, and filter encrypted traffic. Similar functionality is present in lawful intercept systems and solutions enabling the broad surveillance of encrypted communications by governments. Broadly classified as “SSL/TLS interception proxies,” these solutions act as a “man in the middle,” violating the end-to-end security promises of SSL. This type of interception comes at a cost. Intercepting SSL-encrypted connections sacrifices a degree of privacy and integrity for the benefit of content inspection, often at the risk of authenticity and endpoint validation. Implementers and designers of SSL interception proxies should consider these risks and understand how their systems operate in unusual circumstances. -

HP Laserjet Pro Devices – Installing 2048 Bit SSL Certificates

These references are provided for example and demonstration purposes only and are not intended as an endorsement of any products, services, or companies. Introduction A recent publication of the National Institute of Standards and Technology (NIST Special Publication 800-131A) announced that the use of 1024 bit SSL/TLS certificates is no longer recommended and will be “disallowed” after December 31, 2013. The publication recommends the use of 2048 bit certificates to maintain network security and integrity. As a result, most Certificate Authorities (CAs) will no longer issue 1024 bit certificates. And, most Web browsers will no longer honor such certificates as safe and secure. In order to avoid error messages and the risk of a security breach, systems and devices that rely on the SSL/TLS protocols will need to have 2048 bit Certificates installed. -
Threat Landscape Report – 1St Quarter 2018
TLP-AMBER Threat Landscape Report – 1st Quarter 2018 (FINAL) V1.0 – 10/04/2018 This quarterly report summarises the most significant direct cyber threats to EU institutions, bodies, and agencies (EU-I or 'Constituents') in Part I, the development of cyber-threats on a broader scale in Part II, and recent technical trends in Part III. KEY FINDINGS Direct Threats • In Europe, APT28 / Sofacy threat actor (likely affiliated to Russia military intelligence GRU) targeted government institutions related to foreign affairs and attendees of a military conference. Another threat actor, Turla (likely affiliated to Russia’s security service FSB) executed a cyber-operation against foreign affairs entities in a European country. • A spear-phishing campaign that targeted European foreign ministries in the end of 2017 was attributed to a China-based threat actor (Ke3chang) which has a long track record of targeting EU institutions (since 2011). As regards cyber-criminality against EU institutions, attempts to deliver banking trojans are stable, ransomware activities are still in decline and cryptojacking on the rise. Phishing lures involve generic matters (’invoice’, ‘payment’, ‘purchase’, ‘wire transfer’, ‘personal banking’, ‘job application’) and more specific ones (foreign affairs issues, European think tanks matters, energy contracts, EU delegation, EU watch keeper). Almost all EU-I are affected by credential leaks (email address | password) on pastebin-like websites. Several credential- harvesting attempts have also been detected. Attackers keep attempting to lure EU-I staff by employing custom methods such as spoofed EU-I email addresses or weaponisation of EU-I documents. Broader Threats • Critical infrastructure. In the energy sector, the US authorities have accused Russian actors of targeting critical infrastructure (including nuclear) for several years and are expecting this to continue in 2018. -

Computer Security EITA25 Department of Electrical and Information Technology Lund University March 12, 2018, 8-13
Final exam in Computer Security EITA25 Department of Electrical and Information Technology Lund University March 12, 2018, 8-13 • You may answer in either Swedish or English. • If any data is lacking, make (and state) reasonable assumptions. • Use legible hand writing. If your answers cannot be read, you will receive zero points on that problem. • Only pencil and eraser is allowed. • Grading is done as follows. Grade 3 = 20{29 points, Grade 4 = 30{39 points, Grade 5 = 40{50 points. Problem 1. Consider the following permissions on a file in Windows. Determine for each case if Alice, who is member of group Students, can read the file or not. a) User Alice has file permission "write", group Students has file permission "read + write". b) User Alice has file permission "read", group Students is denied permission "read". c) Parent folder has share permission "read" for everyone and file has file permission "write" for Alice. Alice accesses the file over the network. Answer a) Yes b) No c) No (1+1+1 points) Problem 2. Stream ciphers require IVs for practical use. What is an IV and how does it improve the security of stream ciphers? Answer It is a public initialization vector that is unique for each keystream generated under a given key. It is used to make sure that two different plaintexts, p1 and p2, are always encrypted using different keystreams. Adding two ciphertext bits, c1 and c2, encrypted with the same keystream bit, will leak information about the corresponding plaintext bits. i i i i i i i i c1 ⊕ c2 = k1 ⊕ k2 ⊕ p1 ⊕ p2 = p1 ⊕ p2 (3 points) Problem 3. -
