A connected world will be a playground for hackers - Cyber security - The Economist, Sep 2019
"Few companies making connected gadgets have much experience with cyber security"

"AS WAYS TO break into casinos go, a fish tank is an unusual route. Yet that is what was used in an unnamed American gambling house in 2017. It had invested in a fancy internet-connected tank in which the temperature and salinity of the water were remotely controlled. Its owners were not naive: when they installed it, they isolated its controls on their own specific part of their company network, away from all their sensitive systems.

It made no difference. According to Darktrace, a computer-security firm, attackers from Finland managed to break into the tank’s systems, then used it as a stepping stone for the rest of the casino’s networks. They made off with around 10GB of data."

Exclusive: Russia Carried Out A 'Stunning' Breach Of FBI Communications System, Escalating The Spy Game On U.S. Soil | HuffPost Sep 2019
"Both compounds, and at least some of the expelled diplomats, played key roles in a brazen Russian counterintelligence operation that stretched from the Bay Area to the heart of the nation’s capital, according to former U.S. officials. The operation, which targeted FBI communications, hampered the bureau’s ability to track Russian spies on U.S. soil at a time of increasing tension with Moscow, forced the FBI and CIA to cease contact with some of their Russian assets, and prompted tighter security procedures at key U.S. national security facilities in the Washington area and elsewhere, according to former U.S. officials. It even raised concerns among some U.S. officials about a Russian mole within the U.S. intelligence community."

"American officials discovered that the Russians had dramatically improved their ability to decrypt certain types of secure communications and had successfully tracked devices used by elite FBI surveillance teams."

Joel Brenner: "we were neither organized nor resourced to deal with counterintelligence in networks, technical networks, electronic networks.”

"Russian spies also deployed “mobile listening posts.” Some Russian intelligence officers, carrying signals intelligence gear, would walk near FBI surveillance teams. Others drove vans full of listening equipment aimed at intercepting FBI teams’ communications."

Simjacker – Next Generation Spying Over Mobile | Mobile Security News | AdaptiveMobile, Sep 2019
Via Amie Stepanovich

"... Simjacker. We believe this vulnerability has been exploited for at least the last 2 years by a highly sophisticated threat actor in multiple countries, primarily for the purposes of surveillance. Other than the impact on its victims, from our analysis, Simjacker and its associated exploits is a huge jump in complexity and sophistication compared to attacks previously seen over mobile core networks. It represents a considerable escalation in the skillset and abilities of attackers seeking to exploit mobile networks. "

"This S@T Browser software is not well known, is quite old, and its initial purpose was to enable services such as getting your account balance through the SIM card. Globally, its function has been mostly superseded by other technologies, and its specification has not been updated since 2009, however, like many legacy technologies it is still been used while remaining in the background."

How dangerous is the KNOB Bluetooth vulnerability and what should I be - Aug 2019
Via Dale Hatfield

"Security researchers recently discovered a way to intercept a Bluetooth connection between two devices, leading to the ability to plainly view all of the data being transmitted between the two devices. The ‘attack’ was successful on 17 different kinds of Bluetooth chips on 24 different devices that they tested, which means that every popular brand of device that uses Bluetooth is vulnerable."

"In essence, the security researchers figured out how to lower the encryption level used to keep Bluetooth connections secured, by jumping in during the initial negotiation process prior to making a connection."

"In order to actually pull this off in real life, the perpetrator would need a really specialized and expensive piece of equipment, be relatively nearby and could only exploit the connection at the very moment that the two devices where attempting to pair with one another."

Hackers Made an App That Kills to Prove a Point | WIRED, Jul 2019
"... yet months of negotiations with Medtronic and regulators to implement a fix proved fruitless. So the researchers resorted to drastic measures. They built an Android app that could use the flaws to kill people."

"The researchers, who also include Jesse Young and Carl Schuett, say they found it easy to reverse engineer the simple encoding and validity checks meant to protect the signal, enabling an attacker to capture the fob's commands. A hacker could then use readily available, open source software to program a radio that masquerades as a legitimate MiniMed remote, and send commands that the pumps will trust and execute. After establishing that initial contact, hackers can then control that radio through a simple smartphone app to launch attacks"

"Both Medtronic and regulators acknowledge that there is no way to patch the flaws on the affected insulin pump models, or to completely disable the remote feature. "

"Rios says the research group demonstrated its proof of concept app to FDA officials in mid-June of this year; Medtronic announced its voluntary recall program a week later. "

Serious Zoom security flaw could let websites hijack Mac cameras - The Verge, Jul 2019
"Today, security researcher Jonathan Leitschuh has publicly disclosed a serious zero-day vulnerability for the Zoom video conferencing app on Macs. He has demonstrated that any website can open up a video-enabled call on a Mac with the Zoom app installed. That’s possible in part because the Zoom app apparently installs a web server on Macs that accepts requests regular browsers wouldn’t. In fact, if you uninstall Zoom, that web server persists and can reinstall Zoom without your intervention."

Hospital viruses: Fake cancerous nodes in CT scans, created by malware, trick radiologists - The Washington Post, Apr 2019
"But what if the scan had shown faked cancerous nodules, placed there by malware exploiting vulnerabilities in widely used CT and MRI scanning equipment? Researchers in Israel say they have developed such malware to draw attention to serious security weaknesses in critical medical imaging equipment used for diagnosing conditions and the networks that transmit those images — vulnerabilities that could have potentially life-altering consequences if unaddressed."

"Mirsky said the attack works because hospitals don’t digitally sign the scans to prevent them from being altered without detection and don’t use encryption on their PACS networks, allowing an intruder on the network to see the scans and alter them."

Researchers find 36 new security flaws in LTE protocol | ZDNet
"A group of academics from South Korea have identified 36 new vulnerabilities in the Long-Term Evolution (LTE) standard used by thousands of mobile networks and hundreds of millions of users across the world.

The vulnerabilities allow attackers to disrupt mobile base stations, block incoming calls to a device, disconnect users from a mobile network, send spoofed SMS messages, and eavesdrop and manipulate user data traffic."

"The research team's discoveries aren't exactly new. Several academic groups have identified similar vulnerabilities in LTE over the past years on numerous occasions --July 2018, June 2018, March 2018, June 2017, July 2016, October 2015 ... These vulnerabilities have been the driving force behind efforts to create the new and improved 5G standard --which, unfortunately, isn't that secure either, with some researchers already poking holes in it as well."

"They discovered this sheer number of flaws by using a technique known as fuzzing --a code testing method that inputs a large quantity of random data into an application and analyzes the output for abnormalities, which, in turn, give developers a hint about the presence of possible bugs."

"Because the flaws reside in both the protocol itself and how some vendors have implemented LTE in their devices, researchers believe many other flaws still exist in the real world."

Family tracking app leaked real-time location data for weeks - Engadget Mar 2018
"Family tracking apps can be very helpful if you're worried about your kids or spouse, but they can be nightmarish if that data falls into the wrong hands. Security researcher Sanyam Jain has revealed to TechCrunch that React Apps' Family Locator left real-time location data (plus other sensitive personal info) for over 238,000 people exposed for weeks in an insecure database. It showed positions within a few feet, and even showed the names for the geofenced areas used to provide alerts. You could tell if parents left home or a child arrived at school, for instance."

"While the data is safe for now, the incident illustrates a problem with tracking apps as a whole: it's difficult to verify that developers are securing your location info every step of the way. If they don't and there's a breach, it could lead to very real threats that could include physical danger."

Security Researcher Assaulted Following Vulnerability Disclosure - cybersec Feb 2019
"Following a serious vulnerability disclosure affecting casinos globally, an executive of casino technology vendor Atrient has assaulted the security researcher who disclosed the vulnerability at the ICE conference in London"

"These kiosks and the back end server communicate the personal details of their users and send data like drivers license scans (used for enrollment), user home addresses and contact details, as well as details about user activity, unencrypted over publicly accessible internet. When the researcher discovered that the unauthenticated reward server was directly connected to the kiosks on the casino floor they realized that the API the kiosks used was wide open and extremely vulnerable to criminal abuse."

Yes, you can remotely hack factory, building site cranes. Wait, what? • The Register
"Did you know that the manufacturing and construction industries use radio-frequency remote controllers to operate cranes, drilling rigs, and other heavy machinery? Doesn't matter: they're alarmingly vulnerable to being hacked, according to Trend Micro."

"In addition to basic replay attacks, where commands broadcast by a legitimate operator are recorded by an attacker and rebroadcast in order to take over a targeted plant, attack vectors also included command injection, "e-stop abuse" (where miscreants can induce a denial-of-service condition by continually broadcasting emergency stop commands) and even malicious reprogramming. During detailed testing of one controller/receiver pair, Trend Micro researchers found that forged e-stop commands drowned out legitimate operator commands to the target device."

"Just to keep site managers' blood pressure high, Trend Micro highlighted that not only could script kiddies carry out some of these types of attack against industrial plants, a remote attacker could achieve persistent access by using a battery-powered cellular modem dropped off at a quiet part of a site with a drone."

The “robust yet fragile” nature of the Internet | PNAS 2005
Abstract

The search for unifying properties of complex networks is popular, challenging, and important. For modeling approaches that focus on robustness and fragility as unifying concepts, the Internet is an especially attractive case study, mainly because its applications are ubiquitous and pervasive, and widely available expositions exist at every level of detail. Nevertheless, alternative approaches to modeling the Internet often make extremely different assumptions and derive opposite conclusions about fundamental properties of one and the same system. Fortunately, a detailed understanding of Internet technology combined with a unique ability to measure the network means that these differences can be understood thoroughly and resolved unambiguously. This article aims to make recent results of this process accessible beyond Internet specialists to the broader scientific community and to clarify several sources of basic methodological differences that are relevant beyond either the Internet or the two specific approaches focused on here (i.e., scale-free networks and highly optimized tolerance networks).

CenturyLink's outage started in Denver, spread across country - Denver Post, Jan 2019
"For about 30 hours, from the early morning hours of Dec. 27 until late on Dec. 28, chaos reigned on CenturyLink’s system as a faulty third-party network management card in Denver caused a series of outages across the country. "

"For about 30 hours, from the early morning hours of Dec. 27 until late on Dec. 28, chaos reigned on CenturyLink’s system. Western states that depend most heavily on the company’s fiber-optic system were hardest hit, but reports of outages and slower speeds came in from Alaska to Florida, according to downdetector.com."

"Computer scientists borrowed the term “Sorcerer’s Apprentice Syndrome” to describe what happens when a part of a network sends out “packets” of bad information that then get replicated and sent out over and over"

“Once on the secondary communication channel, the invalid frame packets multiplied, forming loops and replicating high volumes of traffic across the network, which congested controller card CPUs (central processing unit) network-wide, causing functionality issues and rendering many nodes unreachable,” the company said in a statement.

"Massey, who worked on cybersecurity issues at the Department of Homeland Security before joining CU, said most states have invested very little in cybersecurity and other safeguards when it comes to their 911 centers. They are not as failproof as they need to be."

According to NANU 2016008 it was marked unusable at 15:36 UTC on 25th January and decommissioned at 22:00 UTC later that same day. Unfortunately (for reasons not yet fully known) the UTC signal on some satellites was off by 13 microseconds. This Case Study charts the activity undertaken by the Chronos support team during and after this unprecedented GPS anomaly event. For some with long memories this is not the first time that SVN23 has caused a problem. The last time was 1st January 2004."

Protecting the power grid from GPS spoofing -- GCN Sep 2018
"It’s relatively simple for bad actors to bring down a power grid by spoofing the GPS signals the grid uses to time stamp sensor measurements, according to researchers at the University of Texas at San Antonio."

The sensors -- phasor measurement units -- are installed in fixed locations throughout the grid and transmit 30 measurements per second to the control center, where operators monitor grid performance and increase or decrease the supply of electricity depending on the readings. That data is time stamped with the signals received by the sensors’ on-board GPS receivers.

"The team is also exploring using the algorithm to protect against time-synchronization attacks against financial institutions, which use the GPS timing data to time stamp financial transactions."

A survey of the existence of GPS interference in Europe « Electronic Environment
"One of the objectives of STRIKE3 is the deployment and operation of an international GNSS interference monitoring network to capture the scale and dynamics of the problem, and to work with international GNSS partners to develop, negotiate, promote and implement standards for threat reporting and receiver testing."

"This article presents measurement results from a survey of the existence of GPS interference and jammers within Europe. The measurement started in the late March 2016 and ended in the beginning of July 2016. Interference detection equipment were deployed ‘as is’ in seven European countries; Sweden, UK, France, Czech Republic, Poland, Slovakia and Finland, see fig. 1. In total eleven different site locations are covered among these countries."

"there is a huge variation in the number of weekly events at each site, with some sites having only a few detections per week whereas others have several hundred ... The most active sites appear to be those next to major roads or in city center locations. These are also the busiest sites in terms of vehicles (which may carry jammers) and other sorts of activity"

", the greatest number of chirp type events (which are likely to be intentional and are associated with vehicle jammers) are seen at site 8 and site 10, with a significant number also seen at site 5. Those three sites are close to busy roads and hence that probably explains the high number of these types of events."

How can airlines stop hackers pwning planes over the air? And don't say 'regular patches' • The Register
Via Dale Hatfield

See discussion thread: https://forums.theregister.co.uk/forum/1/2017/11/15/airplanes_vulnerable_rf_hacking/

"A plane was compromised as it sat on the tarmac at a New Jersey airport by a team of boffins from the worlds of government, industry and academia, we're told. During the hack – the details of which are classified – experts accessed systems on the Boeing 757 via radio-frequency communications."

"A couple of years ago, security researcher Chris Roberts was accused of hacking into the controls of a United Airlines plane in midair via the inflight entertainment system. Roberts tweeted about airplane network security during the flight to Syracuse, New York. He was questioned on arrival by the Feds. However, there is no evidence he accessed flight control systems, and no charges were ever brought.

In 2014, Brad Haines poked air traffic control and ADS-B security, and found various threats to installations."

"Recently designed commercial aircraft – such as Boeing’s 787 and the Airbus Group A350 – were drafted with computer security in mind, we're told, but resisting or preventing cyber-attacks were not on the design criteria list for older aircraft, which still make up the vast majority of airline fleets."

Network security: threats and opportunities for operators
"The software-controlled transformation of CSPs’ organisations and network infrastructures creates both opportunities and risks in terms of network security. The increased openness, speed and flexibility of software-defined networking (SDN) and network function virtualisation (NFV) create a host of new vulnerabilities that increase the level of risk to the organisation and its customers. Conversely, that same openness, speed and flexibility provides the CSP with very much better tools with which to spin-up and deploy security features to detect and mitigate real-time threats in its networks."

"Another example is the risk of DDoS attacks originating in the 5G radio access network. This already represents a threat to network availability in the current 3G and 4G network environments, but this will escalate with the introduction of 5G endpoints capable of supporting up to 100 Mbps. There are new opportunities for vendors in delivering products and feature sets that will meet these new 5G security challenges."
