英会話・英語 アミック What is ransomware?
Ransomware is malicious code that is used by cybercriminals to launch data kidnapping and lockscreen attacks. The motive for ransomware attacks is monetary, and unlike other types of attacks, the victim is usually notified that an exploit has occurred and is given instructions for how to recover from the attack. Payment is often demanded in virtual currency to protect the criminal’s identity.
Ransomware malware can be spread through malicious e-mail attachments, infected software apps, infected external storage devices and compromised websites. In a lockscreen attack, the malware may change the victim’s login credentials for a computing device; in a data kidnapping attack, the malware may encrypt files on the infected device as well as other connected network devices.
Ransomware kits on the deep web have allowed cybercriminals with little or no technical background to purchase inexpensive ransomware-as-a-service (RaaS) programs and launch attacks with very little effort. Attackers may use one of several different approaches to extort digital currency from their victims. For example:
The victim may receive a pop-up message or email warning that if the ransom is not paid by a certain date, the private key required to unlock the device or decrypt files will be destroyed.
The victim may be duped into believing he is the subject of an official inquiry. After being informed that unlicensed software or illegal web content has been found on his computer, the victim is given instructions for how to pay an electronic fine.
The attacker encrypts files on infected computed devices and makes money by selling a product that promises to help the victim unlock files and prevent future malware attacks.
To protect against ransomware attacks and other types of cyberextortion, experts urge users to backup computing devices on a regular basis and update software — including anti-virus software — on a regular basis. End users should beware of clicking on links in emails from strangers or opening email attachments and victims should do all they can to avoid paying ransoms.
While ransomware attacks may be nearly impossible to stop, there are important data protection measures individuals and organizations can take to insure that damage is minimal and recovery is a quick as possible. Strategies include compartmentalizing authentication systems and domains, keeping up-to-date storage snapshots outside the main storage pool and enforcing hard limits on who can access data and when access is permitted.
英会話・英語 アミック Is it cool to tan?
With the warmer weather beginning and spring vacation just finished many of us are either blessing or condemning becoming sun-kissed. Growing up in the UK, a sunny day is something to be celebrated, with short sleeves and shorts, ice-creams and sea sides… and the inevitable red patches of sunburn. Due to the lack of sunlight in the UK, Brits are recommended to have 15 minutes in the sun without using sun-screen, this is because the body generates an essential vitamin through direct contact with sunlight: Vitamin D. This coupled with the notion of “a healthy glow” it has become very popular for us to tan, completely opposite to the traditional “English Rose” portrayed in classical British literature with pure white skin and dark hair.
One of my biggest culture shocks when I first moved to Thailand, was the amount of “whitening” products that were available, certainly comparable to the amount of “tanning” products that are available in the UK. When I moved to Japan, I was expecting to see a similar variety of these “whitening” products and although I have seen some, there are less than I expected. There is a greater selection of sun protection products however and this seems, to me, to be a more natural and healthier option. Although it is not unusual to see a sun parasol in Thailand, they are much more common place in Japan. This with the UV protection clothing and higher SPF sun-screen, it is certainly easier to maintain a whiter skin shade.
Do you think it’s better to tan or not and what are your reasons?
英会話・英語 アミック Early May Bank Holiday in the U.K.
The first Monday of May is a bank holiday in the United Kingdom. It is called May Day in England, Wales and Northern Ireland. It is known as the Early May Bank Holiday in Scotland. It probably originated as a Roman festival honoring the beginning of the summer season (in the northern hemisphere). In more recent times, it has been as a day to campaign for and celebrate workers’ rights.
英会話・英語 アミック Golden Week
I feel very blessed to have spent another wonderful Golden Week with good friends and family. We spent ten days in Phuket relaxing, catching up with friends, island-hopping, and eating authentic Thai food. There are too many highlights for me to mention, but one of them would have to be visiting the islands of Phang Nga and Phi Phi. I have visited these islands over a dozen times and they continue to captivate me. Nature truly has a magical way of healing and rejuvenating your mind and body. The picture below is one of my favorite spots in Phi Phi.
I hope you all had a splendid Golden Week.
英会話・英語 アミック What day were you born?
Some people believe that the day of the week you were born can say a lot about who you are. Fortune-telling by days of birth is different in many parts of the world with astrology being the most popular.
One that I can vaguely recall is a nursery rhyme. I can’t remember which version of the rhyme I learnt so this is the traditional rhyme I found online.
Monday’s child is fair of face,
Tuesday’s child is full of grace,
Wednesday’s child is full of woe,
Thursday’s child has far to go,
Friday’s child is loving and giving,
Saturday’s child works hard for a living,
But the child who is born on the Sabbath day
Is bonnie and blithe and good and gay.
It may ring true for some people, but I don’t take it too seriously. Just enjoy it for its lightheartedness.
