“นี่แสดงให้เห็นว่ามีฝ่ายตรงข้ามที่มีทั้งความตั้งใจและความสามารถในการโจมตีและก่อให้เกิดความเสียหายให้กับโครงสร้างพื้นฐานที่สำคัญของทุกประเทศทั่วโลกและภัยคุกคามนี้จะต้องไม่ถูกละเลย” ผู้ก่อตั้งเครือข่าย Nozomi Andrea Carcano
Ukrainian investigators have confirmed that last month’s power outage in the country was the result of a cyberattack by the same group that struck in December 2015, claiming they may be practising for major attacks elsewhere.
The attack last month was smaller scale than the 2015 blitz which left around 230,000 people without power. It occurred at the Pivnichna substation outside the capital Kiev, sources told Motherboard.
They claimed the same attackers are responsible for other cyber campaigns launched at the same time against the country’s rail provider and Ministry of Finance.
The hackers also used some of the same tactics in both power station attacks, overwriting the firmware on remote terminal units (RTUs), thereby causing them to malfunction and forcing engineers to physically restore power, the report claimed.
It’s not known what malware was employed in this latest attack, although the group is said to have used expertly crafted spearphishing emails to access key systems in this and the related attacks.
Marina Krotofil, a researcher at Honeywell Industrial Cyber Security Lab, who helped with the investigation, told the website that the attack was not meant to have a lasting impact on infrastructure.
“They could do many more things, but obviously they didn’t have this as an intent. It was more like a demonstration of capabilities,” she’s reported as saying.
“Ukraine uses equipment and security protections of the same vendors as everybody else around the world. If the attackers learn how to go around those tools and appliances in Ukrainian infrastructures, they can then directly go to the West.”
While the researchers have yet to attribute the attacks to a particular party, Ukrainian intelligence blamed the 2015 outage on the Kremlin, which would make sense given the ongoing conflict between the two countries, and Russia’s significant muscle in this area.
Researchers at iSight Partners claimed early last year that Russian hacking group Sandworm team was responsible for the 2015 outage, armed with BlackEnergy destructive malware.
Experts agreed with the theory that the Ukraine is being used as a testbed for attacks on other countries.
“This illustrates that there are adversaries, with both intent and ability, to launch attacks and cause damage to the critical infrastructure of every country around the globe, and this threat must not be ignored,” argued Nozomi Networks founder Andrea Carcano.
“Cyber resiliency through defence in-depth measures is needed, and that includes network segmentation, firewalls and visibility solutions. All protectors must re-examine their ICS cybersecurity programs carefully and arm themselves with technology that will enable them to detect and respond to attacks, in real time, if they’re to keep the attackers out and the power on.”

Compliance status
We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience,
regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level.
These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible
to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific
disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML,
adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Screen-reader and keyboard navigation
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with
screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive
a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements,
alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website.
In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels;
descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups),
and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag
for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology.
To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on
as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
Disability profiles supported in our website
Epilepsy Safe Mode: this profile enables people with epilepsy to use the website safely by eliminating the risk of seizures that result from flashing or blinking animations and risky color combinations.

Blindness Mode: this mode configures the website to be compatible with screen-readers such as JAWS, NVDA, VoiceOver, and TalkBack. A screen-reader is software for blind users that is installed on a computer and smartphone, and websites must be compatible with it.
Keyboard Navigation Profile (Motor-Impaired): this profile enables motor-impaired persons to operate the website using the keyboard Tab, Shift+Tab, and the Enter keys. Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
Additional UI, design, and readability adjustments
Font adjustments – users, can increase and decrease its size, change its family (type), adjust the spacing, alignment, line height, and more.
Color adjustments – users can select various color contrast profiles such as light, dark, inverted, and monochrome. Additionally, users can swap color schemes of titles, texts, and backgrounds, with over seven different coloring options.
Animations – person with epilepsy can stop all running animations with the click of a button. Animations controlled by the interface include videos, GIFs, and CSS flashing transitions.
Content highlighting – users can choose to emphasize important elements such as links and titles. They can also choose to highlight focused or hovered elements only.
Audio muting – users with hearing devices may experience headaches or other issues due to automatic audio playing. This option lets users mute the entire website instantly.
Cognitive disorders – we utilize a search engine that is linked to Wikipedia and Wiktionary, allowing people with cognitive disorders to decipher meanings of phrases, initials, slang, and others.
Additional functions – we provide users the option to change cursor color and size, use a printing mode, enable a virtual keyboard, and many other functions.
Browser and assistive technology compatibility
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
