Last November, local fashion and retail group E-Land was also “inquired” by hackers, forcing 23 of the 50 branches of the NC Department Store and NewCore Outlet to suspend operations. Mr. Kim Seung-joo, Professor of Cyber ​​Security at University Korea , commented that as companies are forced to choose to increase their reliance on remote work during the pandemic, cyber attacks malicious code Blackmail has become a bigger threat because they can paralyze the entire working system. This has led to many companies paying a ransom and has led hackers to carry out more attacks. He urged businesses to invest in cybersecurity to prevent the threat in the first place. In response to ransomware attacks in the near future, last month, the Korean Ministry of Information and Communications Technology set up a 24-hour monitoring group to support hacked companies. . The government is now providing assistance to affected companies in system recovery.

The move comes after the attack on the US oil and gas shipping company Colonial Pipeline and the growing damage caused by cybercriminals. The US raised the level of investigation into the crime of extortion hackers to the level of ‘terrorists’. Photo: REUTERS In an internal guideline document sent to law offices across the United States on June 3, the US Department of Justice directed that investigations into ransomware should be coordinated with the central government, specifically: A new task force was established in Washington. “This will be a specialized process to ensure we can track all cases of extortion hackers regardless of where they happen in the US, so we can capture the connection between subjects and proceed to break the whole link,” said Deputy Attorney General John Carlin. Previously, in May, the largest US oil pipeline system, the Colonial Pipeline, was crippled by hackers. Colonial Pipeline has decided to pay hackers who have compromised their systems nearly $5 million to regain access. According to the Reuters , the DOJ’s guidance document specifically mentions the Colonial attack as an example of “the growing threat posed by cybercriminals and digital ransomware to the nation.” . “To ensure we can uncover connections between incidents and investigations across the country and globally, and to paint a big picture of national security and economic threats, The economy we face, we must strengthen and focus our internal monitoring,” the guidance document states. Reuters Citing US officials, the decision to include ransomware attacks in a special process by the Department of Justice shows that the issue is being prioritized. “We’ve used this model in the past for counterterrorism, but never with ransomware,” said Carlin, adding that the process typically applies to cases involving direct national security. In practice, this means that investigators at US attorneys’ offices dealing with ransomware cases will have to share both up-to-date case details and technical information with officials in Washington. The guidelines also require offices to review and report other investigations related to the large-scale cybercrime ecology. According to the guidelines, the list of investigations currently required to be reported to the central government includes: anti-virus services, illegal online forums or marketplaces, cryptocurrency exchanges, cybercriminal server services, botnets, and online money laundering services. “We would like to emphasize that prosecutors and criminal investigators need to report and conduct monitoring of cryptocurrency exchanges, illegal online forums or marketplaces for trading hacking tools. , as well as tracking botnets that serve a variety of purposes,” said Carlin. According to Mark Califano, a former US attorney and cybercrime expert, raising the level of investigation could allow the US Justice Department to “deploy resources more effectively” and “identify common exploits” variables” used by cybercriminals.

UC Browser is developed by UCWeb, a subsidiary of Alibaba (China). This is one of the most popular mobile browsers in Asia, with over 500 million downloads on Google Play alone. According to security researcher Gabi Cirlig, UC Browser silently sent iPhone users’ browsing data (even with incognito mode enabled) to UCWeb servers (registered in China, but located in the US). ). This is in stark contrast to the company’s previous statement, which does not record a user’s “browsing and search history” when incognito mode is activated. More worryingly, UC Browser also collects IDs (unique identifiers) to track users across various websites. The collection of user data happens on both Android and iOS versions, not sure what UCWeb is doing with all this information? Interested readers can watch the video at: “This kind of tracking is done on purpose,” Cirlig told Forbes. When compared with Google Chrome browser and some other popular browsers, he found there is no browser like UC Browser. UC Browser just rolled out a new update last week, but the company never mentioned monitoring users’ browsing activity. Currently the English version of UC Browser has been removed from the App Store, but the Chinese version still exists, and unlike the English version, it does not send data back to the UCWeb server. Earlier in 2019, the UC Browser version for Android also violated Google Play’s policies.

AMD recorded 8.9% growth in the first quarter of 2021, the highest in 15 years In 2020 and into the first quarter of 2021, AMD has focused on high-end desktop CPUs and EPYC chips for servers. The first quarter of the year recorded a record increase of 41% over the same period last year, which is the highest number for the CPU market in 25 years. AMD’s biggest growth most recently came in 2006, when the chipmaker saw its server CPU market share increase from about 5-7% to about 22% in just 18 months with the 64-bit Opteron processor. bits. Then, Intel overtook AMD to let Intel regain its leadership in technology and hold it for 10 years. AMD has launched EPYC Milan and it is used for data centers and supercomputers. Consistent growth in the first quarter will propel AMD further in its goal of becoming a leader in the server CPU segment. The choice of EPYC chip has proven that AMD’s direction is appropriate in recent times. One question is what the growth of ARM architecture means for ARM and Intel in the near future, while Nvidia, Microsoft and others are gradually moving to produce ARM-based CPUs. As for Intel, most recently launched Rocket Lake processors and they compete directly with AMD Ryzen 5000. However, Intel’s chips are more commonly found in retail stores at very affordable prices. competition while AMD’s chips are still rare on store shelves. AMD still has a strong portfolio of next-gen EPYC CPUs such as the 4th Gen EPYC Genoa chips that are expected to be announced next year and will feature the all-new Zen 4 core architecture and a host of other features to addresses Intel Sapphire Rapids & Granite Rapids Xeon CPUs.

Using a separate wifi for smart home systems is necessary because sharing a wifi system has many potential safety risks. Smarthome prioritizes the system to be able to self-alert to abnormal intrusion to ensure safety, so users should use devices with automatic alarm setting feature. When there is an unusual intrusion, a notification will be sent to the homeowner’s phone immediately. In smarthome, not only home lock, smart home control applications need abnormal login warning feature, this helps homeowners recognize the risk of network attack to implement instant protection options. then. In a smart home, if there is a smart speaker with a screen or camera, users should consider turning off or covering the camera when there is no need to use it. This is similar to the fact that many people have a habit of covering the webcam on their laptop to avoid unfortunate images being recorded. Smart devices of unknown origin are at risk of being installed with spyware, which is easy to lose control and have data stolen. To be safe, it is recommended to use equipment from reputable companies, need to check the company history, product support period. From this information, a decision can be made whether to buy the product or not. And more specifically, it is very important to check the owner of the servers that will contain his home’s information because most smarthome devices used in the home communicate with servers in the cloud. In the process of studying the operation of the smart home control system, security experts have discovered serious security holes. Security flaws in the cloud infrastructure and remote code execution, causing a third party to acquire the “super user” right to access and control the smart home system.

In addition, the figure has been maintained very well. She still takes the girly route, especially in private. The airport clothes are all dressed between 20-30 years old. Recently, Yang Ying has rarely appeared at the airport. It has been a long time since the last airport show. This time she wore a yellow denim jacket and skirt with small white shoes, fresh and handsome. Yellow drives away the small heat of early summer in a second, and is full of brightness. At this time, many fashionable elites have put on a variety of colored items. Yellow is the most unforgettable color.

Yang Ying’s goose yellow is not so eye-catching, fresh and soft. The denim jacket and the denim half skirt give her a girlish atmosphere. Denim skirts are more feminine than jeans. Denim jackets and denim skirts are all solid colors, basically no other colors are added, and they look very simple. Yellow itself is already very colorful. No other colors are needed. It is simple and high-end. The denim jacket has both a zipper design, a vertical row of concealed buttons, and a symmetrical tooling pocket. There are many small designs.

Inside the denim jacket is a white T-shirt. The combination of light yellow and white is fresher and brighter than matching black. The T-shirt is also pure white, and the shape follows the ultimate simplicity. The T-shirt is pierced into the denim skirt to create the best proportions. The denim skirt has a simpler design, with the simplest silver buttons, echoing the concealed buttons on the top. Both tops and skirts are of the more self-cultivating styles, especially tops, which are short styles. Such suits can also be worn by small people and are fashionable and versatile.

The short skirt reveals beautiful legs to the greatest extent. Yang Ying’s legs are slender and slender. The white shoes on her feet are not the same in general style. The soles are thicker and look like ultra-short Martin boots. They are cooler than ordinary white shoes. . Yang Ying’s crotch is not very good-looking, this time the shape perfectly covers the crotch, the T-shirt and short skirt wear a loose feeling, not close to the waist and crotch. Apple-shaped girls are very suitable to wear this way, without deliberately highlighting the waistline, straight skirts are very good to modify the figure, hidden meat can lengthen the figure.

Wearing a black baseball cap on her head, Yang Ying likes baseball caps privately. Masks and hats cover her small face. The simple white letters break the monotony of the hat. The letter baseball caps will never go out of style. Hair is soft and natural. During this period, black long straight hair is all the rage in domestic entertainment. This kind of hairstyle is pure and neat, returning to the feeling of first love in a second. The yellow denim suit comes from the brand Alberta Ferretti. Although it is a suit, it can also be worn separately. It must have a different feel. The shoes are from Dior.

The 31-year-old Yang Ying is still so girly. This body shape shows a full of pure vitality. Wearing a round neck can not block the slender neck. The head-to-body ratio and body ratio are very superior. She deserves to be a female star. From the side angle, I saw the red heart on the white shoes, and there was a surprise. Appropriate red embellishment always makes people’s eyes bright. Looking down on the screen of the mobile phone, people who don’t know will completely think that she is an 18-year-old young girl, and Yang Ying is in a good state.

Denim items are classic and timeless, especially denim skirts are liked by many urban girls. If you want to wear a novel look, colorful denim skirts are the first choice. In addition to the yellow line, Yang Ying’s pink denim skirt is also impressive. It is no longer a miniskirt, but a knee-length skirt, but with diagonal slits and cleverly exposed legs. In addition to the split ends, the waistband is also very unique and irregular in design. These two points make the denim skirt different from the general style in an instant, and the small personality is just right.

Paired with white T-shirt and white shoes, it is full of freshness. The color denim skirt is matched with white single product, and the freshness is doubled. There is a small flower on the T-shirt, which is simple and chic. The hats and white shoes on the head have pink patterns. This color echoes the real high-end. As the top stream of the post-85s, Yang Ying has been rumored that resources have dropped a lot during this period, but there will be no significant short-term. The change depends on whether the follow-up can counterattack by word of mouth?

Doctor Web researchers discovered 10 seemingly harmless apps on AppGallery – Huawei’s official app market – that contain codes that connect to malicious C&C servers to take over additional configuration and components. These additional components bypass the user, automatically signing up for the paid service. To cover the phone’s owner, they demanded access to the notification and then interfered with the SMS verification code sent by the paid service. According to experts, the malicious code will subscribe to up to 5 such services, although developers can change the limit at any time. The list of infected applications range from virtual keyboards, photography, launchers, texting to stickers, games. Most have the same developer, Shanxi Kuailaipai Network Technology. In total, 10 apps were downloaded by more than 538,000 Huawei users. Doctor Web reported to Huawei and the company removing them from AppGallery. However, downloaders still have to manually delete the device. Below is a list of software that need to be removed immediately: Super Keyboard, Happy Color, Fun Color, New 2021 Keyboard, Camera MX – Photo Video Camera, BeautyPlus Camera, Color RollingIcon, Funney Meme Emoji, Happy Tapping, All-in-One Messenger. Experts say that modules downloaded from the malicious AppGallery also appear in other apps on Google Play. Once activated, they contact the remote server to receive the configuration file, which contains the task list, the paid service website, and the JavaScript mimics the user’s actions. The Joker malware was born in 2017, continuously detected in apps on Google Play Store. In October 2019, Kaspersky malware analyst Tatyana Shishkova tweeted about more than 70 malicious applications on the Google market. According to Google, they have removed about 1,700 Joker malicious apps since 2017. Du Lam (According to BleepingComputer)
