Original SIM card but still occupied by others Ms. ATH (in Binh Duong) reflected on 2-3 days, she discovered that her phone displayed a message that could not be called, so she went to VNPT Binh Duong Business Center to ask for a check. Here, the technical staff said that the SIM card is not damaged, still works two-way. On March 4, she went to the center to ask for a new SIM card. After that, the phone works normally. On March 12, Ms. H. logged into her credit card account to check and found that the money in the account had been withdrawn in the form of payment for purchases. Suspecting that her SIM information was exposed during the SIM rework, Ms. H. went to VNPT Binh Duong Business Center to find out. Only now did she know that on 2-3 days there was a transaction to replace her SIM at a VNPT center in Ho Chi Minh City. Ms. H. said that this SIM phone number has been registered by her owner before. Now suddenly my SIM was declared and appropriated by someone else, leading to the loss of her credit card more than 58 million dong. “During the settlement process, the representative of VNPT HCMC (where the SIM exchange happened) said he would support me with a scratch card worth 2 million VND, but I did not accept it. The main reason for losing money is because the network operator re-issued the SIM in the wrong process, not because of me, “- Ms. H. shared. Ms. ATH was upset because someone else took control of her phone SIM, so her credit account lost more than 58 million dong. Photo: DANG LE Another case is Mr. Trieu Duc Khai (in Thai Binh) also said on April 21, he made a complaint to VNPT Center in Thai Thuy district, Thai Binh. The content of the complaint about his VinaPhone SIM, although registered by the owner, was still controlled by others, leading to the loss of 35 million VND in his credit card. Through working with VNPT in Thai Thuy district, it was determined that someone had impersonated him to carry out the procedure to lose the SIM and make a new SIM with the subscriber number that Mr. Khai was using. This person only declared five phone numbers to call out, come to the nearest, and then be given a new SIM. Occupying SIM is a trick to appropriate money Exchange with Ho Chi Minh City Law Vo Do Thang, Director of Athena International Security and Network Administration Training Center, said that through the two cases above, it shows that if anyone reports the loss of SIM and only needs to provide five phone numbers to call. going, calling recently, committing to subscriber owner rights to be re-issued with a new SIM is not good at all. This has created a loophole for crooks to steal other people’s SIMs, to the detriment of genuine SIM users. According to Mr. Thang, most of the victims in the SIM loss cases were taken by fraudsters by making online payments. To pay for online purchases, there are three factors: The first is a mobile phone number. The credit card holder must register this phone number with the bank to authenticate transactions and receive bank notifications. The second is the card number (a series of numbers printed on the front of the credit card). The third is the OTP (one-time password) verification code sent to the phone number registered with the bank. In the working minutes and written responses to Ms. H. and Mr. Khai, the network operator confirmed that re-issuing SIM cards to others was not in accordance with the process. Photo: DANG LE. After hijacking the right to use the SIM, the crooks will take the victim’s credit card number to pay online, then use the newly issued SIM to receive the OTP code and complete the payment. The victim’s credit card number has been stolen by the crooks before, appropriating the phone SIM is only the last step to perform the act of appropriating money. According to Mr. Thang, not everyone who loses their phone SIM will lose money in their credit cards and bank accounts. Only when they have had their credit card or account information exposed before can crooks steal money. The victim’s credit card information may be exposed during previous online transactions. The cause is usually because the victim has filled out information on fraudulent websites, installed malicious code on the phone to steal card information, opened attachments of unknown origin or it can also be due to credit institutions. does not guarantee safety in terms of security,” Thang shared. In the working minutes and written responses to Ms. H. and Mr. Khai, the network operator confirmed that re-issuing SIM cards to others was not in accordance with the process. Photo: DANG LE The network operator did the wrong process In both cases mentioned above, in the process of working with customers, the operator has confirmed that the teller when carrying out the SIM reissuance procedure only requires the customer to provide five outgoing and incoming phone numbers. subscriber ownership is not the correct procedure. In response to the recent complaint of VNPT Center in Thai Thuy district, Thai Binh province against Mr. Trieu Duc Khai, it is clear that because of this unfortunate incident, VNPT Center of Thai Thuy district has apologized to customers. The material damage that the impostor causes to the customer, the center will fix and compensate for the loss. As for the case of Ms. ATH, VNPT HCMC said that it will accompany the customer to provide necessary information to serve the investigation agency.

Hanoi is the locality with the most people downloading the anti-epidemic application Bluezone Out of 33 million people using Bluezone, more than 20.58 million people have entered their phone number in the information on the application. The number of people providing phone numbers to the authorities has increased by nearly 1 million people compared to April 28, 2021. The two localities leading the country in the number of people downloading the Bluezone application are Hanoi (3.1 million people) and Ho Chi Minh City (2.83 million people). In the opposite direction, provinces like Dien Bien (70,500 people), Tuyen Quang (121,000 people), Yen Bai (130,000 people), … are the localities with the lowest number of people downloading Bluezone. Considering the percentage of population, Da Nang (43.7%), Hai Duong (40%), Hanoi (38.6%), Quang Ninh (37%), Bac Ninh (34%) are localities has the most number of Bluezoners. However, there is a fact that the number of people who download and actually use the Bluezone application is still a significant difference. In Hanoi, where the most people download Bluezone, the number of Bluezone accounts actually active is only 1.23 million, accounting for 40% of the total number of accounts. Meanwhile, in Ho Chi Minh City, the number of real Bluezone users (turn on Bluetooth for Bluezone to work) is about 1.1 million people, accounting for 38% of the total number of accounts. The same thing happened in Da Nang (40%), Hai Duong (38%), Quang Ninh (38%), Bac Ninh (39%), Hai Phong (38%), Thai Nguyen (38%) when not Which province or city has the number of people actually using Bluezone exceeding 50% of the population. Currently, Hanoi, Bac Ninh, Bac Giang, Vinh Phuc, Da Nang,… all have documents to encourage people to apply technological solutions such as electronic medical declaration and install Bluezone application to prevent , anti-epidemic. The Bluezone application is currently one of the five recommended technology solutions to prevent the spread of Covid-19. This is a low energy Bluetooth technology application solution. Smartphones with Bluezone installed can communicate with each other, recording close contact. The exposure history data will only be saved on the user’s mobile device. When there is a new infection and that person’s mobile phone has Bluezone installed, the contact history will be used to alert those who also have Bluezone installed and have been in close contact with the case. Bluezone can also help alert F2 people (close contact with F1). Bluezone warns if the user has been in close contact with someone infected with Covid-19, helping to reduce the risk of spreading in the community, helping people return to normal life.

The case that the information of 533 million Facebook accounts has just been released by hackers has made the issue of user privacy once again the focus of all attention. Agreeing on the fee of 5 million dong to regain the account after clicking on a strange link sent by a friend thanks to a vote on Facebook, Ms. LA, the owner of a famous beauty spa in Hanoi, spent 2 more days considering the proposal. about identity verification. Due to the characteristics of her job and the desire to create credibility with her partner, Ms. LA accepts to spend an additional 50 million to ask an intermediary to register for a green certificate. People who need to authenticate their Facebook accounts and other social networks like LA are not rare, especially business people, or celebrities. They are willing to spend a small amount of money to assert something that is their own property. While some platforms allow for free and simple identity verification, with Facebook it is both a difficult challenge and an intermediary fee is an option that is almost mandatory. That seemingly absurd thing is still happening every day, every hour, but no one is sure whether those verified accounts are guaranteed forever or not, because of the status of blue-tick accounts being occupied. becoming an online sales channel in recent times is easy to find. Especially when information about the data of 533 million Facebook users has just been released, many people cannot help but worry. The above data source is being sold by hackers on a hacker forum last week, including information such as phone number, login ID, full name, home address, date of birth, profile and email address … Which involves users in 106 countries, with 32 million Americans, 11 million British and 6 million Indians. In this regard, Facebook said the stolen data did not include users’ financial, health and password information. However, these data can provide valuable information for hackers and other breaches. More importantly, this is not the first time Facebook’s user data has been exposed on a large scale. Facebook user data is regularly leaked The 2015 cult case involving the British consulting firm Cambridge Analytica illegally used the personal data of more than 87 million Facebook users to target political ads. This is a scandal that caused Facebook to accept a settlement of up to $ 5 billion, and also caused founder Mark Zuckerberg to testify before the US Congress. Then in September 2019, a database of more than 400 million phone numbers related to Facebook accounts was released, including about 50 million Vietnamese users. Just 3 months later, the information of 267 million users including login IDs, names and phone numbers continued to fall into the hands of hackers. At the same time, the data leak in Belgium and Luxembourg, including that of European Justice Didier Reynders, many EU cabinet members and diplomats, has caused Facebook to suffer for a while. long time. However, Facebook explained that these data leaks were not caused by hackers breaking into the system, but rather by a vulnerability in the sync communication tool that was exploited by vandals in 2019. Facebook later The company has discovered the vulnerability and fixed it, and confirmed that similar incidents will not happen again in the future. Meanwhile, Mike Clark, Facebook’s director of product management, is constantly moving to try to downplay the impact of this large-scale leak. By March 2021, netizens were again shocked by the information that the data of 41 million Facebook users in Vietnam was distributed by hackers. Talking to a VietNamNet reporter at the time, a Facebook representative acknowledged that the leaked data was from users of this social network, but said “this may be information obtained before we (Facebook – PV) made changes over the past few years to protect users’ information. However, whether Facebook really protects users’ information according to what the head of this platform often says, that is another story. Judging by the recent situation, it seems that the problem of leaking Facebook user information is difficult to completely solve and needs to be looked at in detail. The spread of user information may first be because Facebook did not pay attention to this aspect, nor did it establish a complete and strict system to protect user information. At the same time, after a data breach, Facebook did not thoroughly summarize the problem, how to fix loopholes and prevent new problems from appearing. Not only that, a Facebook spokesperson said it is not clear which users should be notified in the recent incident. Because users cannot patch the vulnerabilities themselves and their personal data has been spread on the Internet, Facebook will not specifically notify the users involved. As a result, Facebook’s performance in this area is relatively poor, and user data leaks are frequent. After all, compared to other social software, users’ dependence on Facebook is still very high. If it leaks many times, I am afraid that it will easily cause irreparable losses and bad consequences. Legal privacy of Facebook users With the data of 87 million users exposed in the Cambridge Analytica scandal, the 10 countries with the most Facebook accounts being collected are the US, Philippines, Indonesia, UK, Mexico, Canada, India, Brazil, Vietnam and Australia. Vietnam has 427,446 user accounts whose data has been collected. CEO Mark Zuckerberg admitted that Facebook made mistakes and that his company failed to protect customer data, losing users’ trust. “We have a responsibility to protect your data, and if we can’t do that, we don’t deserve to serve you,” Zuckerberg wrote in a post on his personal Facebook page after the scandal. In addition to the $5 billion settlement with the US Federal Trade Commission (FTC) at the time, the two sides reached a landmark settlement against allegations of misuse of user data. . According to the settlement reached by the FTC, when more than 500 user information is illegally stolen, Facebook is required to report it within 30 days. In connection with this case, Facebook also had to pay £500,000 (about $ 649,000) after a fine from the UK Information Commissioner’s Office (ICO). By October last year, a user group called Facebook You Owe Us in the United Kingdom, led by the law firm Milberg London and supported by former CEO Richard Lloyd, continued to sue Facebook and seek compensation. another large sum. Meanwhile, most of Facebook’s data disclosure scandals have a direct impact on users of this social network in Vietnam. No one has been able to determine how many of the 427,446 Vietnamese user accounts in the Cambridge Analytica incident, or the 41 million accounts in the newly announced case in March 2021, were affected, even appropriated and had to be stolen. spend a small amount of money to get your account back like LA One thing is for sure, users are solely responsible for the security of personal account information in accordance with the general provisions of most platforms, including Facebook. However, if personal information on platforms like Facebook is leaked without subjective reasons from the user, on the contrary due to a security incident from the platform, who will be responsible for this? Since Facebook is obligated to compensate users in the US or EU affected by security incidents on the platform, why are 69,280,000 users using this social network in Vietnam, accounting for 70 .1% of the entire population (statistics as of June 2020), of which many are victims of Facebook incidents, are automatically responsible? This question, the writer would like to leave the answer open, because currently Vietnam does not have specific regulations and sanctions that apply specifically to social networking platforms, or the object of application in this case is outside of Vietnam. the scope of control under applicable law due to not having a home office. However, it is a problem that needs to be solved in the near future…

Basically, landline numbers are now extended to 10 numbers, equivalent to mobile phone numbers, creating uniformity. In addition to the area code, the customer’s fixed subscriber number does not change. Digital warehouse planning opens up conditions for the development of mobile communication networks and the Internet of Things. Of course, not everyone remembers the new landline code system of the provinces and cities. What is the phone area code for Tay Ninh? The landline area code has been transferred to the end of 02x, extending the number of subscribers to 10 numbers. As mentioned, the landline area code is transferred to the end of the 02x number. Previously, the landline code in Tay Ninh was 066, now using the area code 0276. Tay Ninh landline phone number has the form 0276xxx.xxxx, in which the last 7 digits are the customer’s unchanged fixed-line subscriber. To simultaneously convert these numbers in the smartphone directory, users can install supporting applications from the Android and iOS platform stores. Of course, if you call a landline in the same province, the user does not need to enter the area code.

Hackers can obtain sensitive user’s information through the vulnerability in AirDrop. Photo: TU Darmstadt. “An attacker could obtain a user’s phone number and email through AirDrop,” the team said. “They just need to use a device with Wi-Fi capable, reach the target at close range to start the mining process by opening the sharing feature on iOS or macOS device.” According to the 9to5mac There are two steps in the mechanism of AirDrop action leading to this critical vulnerability. First, in order to provide users with the option “Contacts Only” in the AirDrop sharing feature, Apple devices silently collect information on devices within the connection range. To see if the “other party” is in the contacts list, AirDrop uses a mutual authentication mechanism, comparing the user’s phone number and email address with the entries in the address book. The device authentication step in the directory can be exploited to get information. Photo: Monica Chin. In the next step, data is exchanged for both parties. Despite encryption, Apple uses a relatively weak hashing mechanism. Security experts can decompile the hash using a simple technique like a brute-force attack. The team addressed the AirDrop vulnerability with a more secure approach, they named PrivateDrop. However, Apple did not move after being warned of the risk of personal information leaks and privacy breaches. In the immediate future, experts from the Technical University of Darmstadt advise users to protect themselves by disabling AirDrop discovery in the system settings and not opening the share menu. The detailed results of the study will be presented at the USENIX security Symposium taking place in August. Why does iPhone not have USB-C port? In the past 5 years, USB-C has become the suitable connector for a wide variety of devices such as Android phones, laptops and tablets. However, Apple still doesn’t make iPhones with USB-C ports.

Ms. Bui Hang (Thanh Xuan – Hanoi) said: “For a long time there have been no spam calls to my phone, but since the day I applied for stock account registration, advertising calls appear thick. Special, 2-3 days. There was a conversation I had, the other end said that I knew I had submitted the application, but it was a stock trading profile in the domestic market. That employee invited me to join international stocks for more benefits. Why do they know my information so well? “. According to the reflection of Mr. Le Manh Dung (Long Bien-Hanoi), recently, this customer is often tapped. When calling back, there are also introductory content, advertising services. According to the Telecommunications Department, next time, the Department will continue to promote measures to manage and handle violations related to telecommunications waste (spam sim, spam calls, spam messages); At the same time, there are solutions to prevent fake phone calls, prevent the sale of pre-activated sims … contributing to ensuring security and order.

On the KrebsOnSecurity blog, cybersecurity expert Brian Krebs issued a warning about the leaked data, including the application user’s email address, phone number, license plate number, customer birth date, and email address. and password. (Photo: Seacoast Online) Information about the data breach was first discovered by the threat intelligence firm Gemini Advisory based in New York City (USA). “Gemini Advisory shared an image showing that my personal data was publicly available on a crime forum, including my ParkMobile account information in screenshots, along with information about the data. stolen.
