The Autodidactic Universe Up for some light reading? Theoretical physicists working with Microsoft released a paper on Friday asserting that the universe is essentially a machine-learning computer. The researchers working with Microsoft published a titled “The Autodidactic Universe,” . It describes our universe as an algorithm that’s continuously learning about itself. Like humans, the universe itself observes and learns about its own laws and structures — and changes as a result. From the paper: “For instance, when we see structures that resemble deep learning architectures emerge in simple autodidactic systems might we imagine that the operative matrix architecture in which our universe evolves laws, itself evolved from an autodidactic system that arose from the most minimal possible starting conditions?” The researchers behind this paper built on research done by physicist Vitaly Vanchurin . Impossible Physics So we’re all living in a huge self-learning algorithm… but what does this mean? For one thing, it makes unifying physics as a whole practically impossible. After all, if the universe is capable of learning and changing its laws as a result, the laws of physics will also be in constant flux. That means that what we currently understand as the laws of physics might have functioned differently in the universe’s past — and will change in its future as well. Of Memes And Men The paper’s authors also dive into the idea that memes are a great example of how the universe might not just be learning out of its own survival — but also purely because it just wants to learn. “The example of memes in human social structures show that a...
Administrators typically use Remote Desktop Protocol (RDP) in order to manage Windows environments remotely. It is also typical RDP to be enabled in systems that act as a jumpstation to enable users to reach other networks. However even though this protocol is widely used most of the times it is not hardened or monitor properly. From red teaming perspective dumping credentials from the lsass process can lead either to lateral movement across the network or directly to full domain compromise if credentials for the domain admin account have been stored. Processes which are associated with the RDP protocol can also be in the scope of red teams to harvest credentials. These processes are: The above processes can be targeted as an alternative method to retrieve credentials without touching lsass which is a heavily monitored process typically by endpoint detection and response (EDR) products. The service host (svchost.exe) is a system process which can host multiple services to prevent consumption of resources. When a user authenticates via an RDP connection the terminal service is hosted by the svchost process. Based on how the Windows authentication mechanism works the credentials are stored in memory of the svchost process in plain-text according to the discovery of Jonas Lyk. However, looking at the process list, there are multiple svchost processes so identification of which process, hosts the terminal service connection can be achieved by executing one of the following commands. Querying the terminal service: Querying which task has loaded the rdpcorets.dll: Running netstat: Looking at the memory strings of the process the password is displayed below the username.

Richard Addiscott (Gartner) Australian organisations are expected to spend over $4.9 billion on enterprise information security and risk management products and services by the end of 2021. This is according to analyst firm Gartner, which claimed spending in the market this year will increase by 8 per cent, year-on-year — higher than 2020’s 6 per cent. Driving this need for IT security and risk solutions, according to Richard Addiscott, senior research director at Gartner, include high profile cyber attacks like the SolarWinds hack, as well as changes to the Security Legislation Amendment (Critical Infrastructure) Bill 2020 and regulatory obligations. Out of the whole enterprise information security and risk management market, security services are expected to be the segment with the highest value this year, with it forecast to reach $3.2 billion in 2021 — representing growth of 7.3 per cent, year on year. Meanwhile, cloud security is anticipated to be the highest growing segment with growth of 33.8 per cent forecast for this year, to $15 million. While up by over a third, this is down from its growth in 2020, when the segment grew by 50.4 per cent. Regardless, the growth in this segment should come as no surprise when considering the firm’s 2021 Gartner CIO Agenda survey from October. Back then, it found 67 per cent of respondents in Australia and New Zealand planned to increase investments in cyber security this year, coming second only to business intelligence and data analytics. Additionally, the survey also found 53 per cent of CIOs intended to invest into cloud services and solutions. Addiscott said Australian government and private sector clients’ priorities...
Overview Machine learning models trained using gradient descent can be forced to make arbitrary misclassifications by an attacker that can influence the items to be classified. The impact of a misclassification varies widely depending on the ML model’s purpose and of what systems it is a part. Description This vulnerability results from using gradient descent to determine classification of inputs via a neural network. As such, it is a vulnerability in the algorithm. In plain terms, this means that the currently-standard usage of this type of machine learning algorithm can always be fooled or manipulated if the adversary can interact with it. What kind or amount of interaction an adversary needs is not always clear, and some attacks can be successful with only minor or indirect interaction. However, in general more access or more interaction options reduce the effort required to fool the machine learning algorithm. If the adversary has information about some part of the machine learning process (training data, training results, model, or operational/testing data), then with sufficient effort the adversary can craft an input that will fool the machine learning tool to yield a result of the adversary’s choosing. In instantiations of this vulnerability that we are currently aware of, “sufficient effort” ranges widely, between and weeks of commodity compute time. Within the taxonomy by , such misclassifications are either perturbation attacks or adversarial examples in the physical domain. There are other kinds of failures or attacks related to ML systems, and other ML systems besides those trained via gradient descent. However, this note is restricted to this specific algorithm vulnerability. Formally, the vulnerability is defined...
Institution of Electronics and Telecommunication Engineers , Nagpur Centre has organized a webinar on topic “ Cyber Security for Women. “Senior Police Inspector Ashok Bagul was key note speaker. Many viewers was on line to understand the modus operandy of cyber crime and remedies to overcome it. Dr. Soni Chaturvedi Asso Professor form PIET was Coordinator for event. Dr. Sanjay Badjate Chairman IETE and Principal SBJITMR, Dr. Suresh Rangankar from SVPCETand Secretary IETE, Dr. Salim Chavan Principal GWCET , Dr.Rajkishor Tugnayat, Principal SSACECE Wardha , Dr. Bhushan Joshi Principal Cummins COE Nagpur and many more members of IETE was on line for webinar. Dr Sanjay Uttarwar a renowned academician and orator from central India and ,Principal of VIT Nagpur was present online for the event. Program starts with introduction of guest and necessity of awareness about cyber crime. At the beginning organizer elaborate the need of hour and importance of cyber security in today’s busy life. During his lucid delivery SPI Ashok Bagul explains the various modes of cyber crime and narrate the consequences of care less attitude on the part of women. Generally it is observed that some womens are casual about their financial transactions and didn’t follow security norms, which results in occurrence of cyber crime. Now a days cyber crime is a burning topic and every now and then we observe that there is occurrence of it in online transactions in Banks. One should not share its credentials, PIN , OTP to any unknown person for any cause. Banks are also alerting us many times for not to share it. Speaker shares the other cyber crimes...
Welcome to Cyber Security Today. This is the Week In Review edition for the week ending Friday March 12th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. In a few minutes I’ll talk with this week’s guest contributor, Terry Cutler of Cyology Labs. But first a look at three of the top news items from the last seven days: IT administrators continue patching their Microsoft Exchange Servers. It’s over a week since urgent updates were issued to cover four serious vulnerabilities called ProxyLogon. However, there’s evidence Exchange Server administrators are not working quickly: On Tuesday — a week after the first alert — Palo Alto Networks said web scans suggest 125,000 internet-connected Exchange servers around the world were still vulnerable, including 4,500 in Canada and 33,000 in the U.S. UPDATE: After this podcast was recorded Palo Alto Networks issued new figures. The number of unpatched servers detected by its Expanse platform had dropped Thursday to 2,700 in Canada and 20,000 in the U.S. One incident response firm here told me on Wednesday that it knows four Canadian organizations had been hacked shortly before Microsoft issued its patches. Among the victim organizations is Norway’s parliamentary email system. Security researchers from ESET think as many as 10 threat groups are taking advantage of vulnerable Exchange servers. Terry and I will talk about this crisis in a few minutes. Verkada is a cloud-based provider of video security for organizations that says its systems are secure by default. However, this week it suffered a major system compromise. According to Bloomberg News, a group of anti-surveillance activists say they accessed and captured live...
