What is tabnabbing?

Tabnabbing is a phishing attack that takes advantage of an idle tab in your internet browser. When a malicious script detects that the user has moved to another tab or has been inactive for some time, it quietly refreshes the idle background tab, redirecting it to a fake login page of a seemingly legitimate website. When you click on the tab, you’ll probably assume that you opened the site yourself. If you log in, your credentials are sent to the owner of the malicious website.

To prevent tabnabbing, keep as few tabs open as possible. Check the address bar for the correct url. Look out for differences between the page and the genuine site (e.g., spelling mistakes and unusual layouts).

Tabnabbing is a social engineering attack. It depends on the victim’s attentiveness and the ability of the hacker to con the victim into believing in his malicious site.

What types of gardens are there in the world?

World of Gardens

In every part of the world, people have a favourite kind of garden. In a formal garden, flowers are arranged in squares, circles, or fancy shapes. Bushes are often trimmed to points, squares, or balls. Garden paths are long and straight. In Japan, many gardens have little bridges in them. In India, gardens often have ponds filled with water lilies. Gardens in Hawaii may have many ferns. Gardeners in other parts of the world often copy these favourite gardens.

Which are the sweetest smelling flowers?

A Scent Garden

One of the most wonderful things about plants is the way some of them smell. Lovely scents come from their flowers or their leaves.

The rose is a sweet-smelling favourite around the world. The sweet pea is a fragrant climbing plant. The tiny, white, bell-shaped lily of the valley has a strong perfume. Many people think that heliotrope smells like vanilla, apple, or cherry pie. One kind of cosmos smells like chocolate.

Fragrant flowering shrubs include the winter jasmine and the gardenia. The leaves of the myrtle plant have a spicy smell when crushed. Daphne and lilacs are also favorites.

How do you start a Rock garden?

A Rock Garden

If your garden has a sunny place that slopes a little, like a small hill, you can make a rock garden. It should look like a tiny bit of mountainside, where small, bright flowers grow among the rocks.

First, bring rocks to the slope. Scoop out shallow holes for them. Put the biggest rocks at the bottom. Put the smaller stones higher up on the slope. Place some of them close together and some further apart. At least half of each rock should be buried in the soil.

Finally, plant small ferns and flowering plants between the rocks. Use plants that won’t grow more than 30 centimetres high.

How do you start a butterfly garden?

A Butterfly Garden

It’s hard to imagine anything prettier than the flashing colours of butterfly wings in a sunny garden. You can grow a garden to attract butterflies by simply choosing the right plants.

Butterflies like to sip nectar, so colourful flowers that make a lot of sweet nectar attract them. Queen Anne’s lace attracts butterflies called black swallowtails. The perfume of sweet William, lavender, and heliotrope also will attract butterflies to your garden. Butterfly weed, sunflowers, and peonies are other butterfly favorites.

Butterflies also will come to a garden to lay their eggs on plants that their caterpillars like to eat. Milkweed is one of these plants. The caterpillar of the monarch butterfly eats milkweed. The caterpillar of the black swallowtail butterfly eats parsley. Several types of caterpillars feed on nettles and clover.

To welcome butterflies, you can put out large flat rocks for them to “sunbathe” on. You might also provide puddles of water where they can drink.
