Wardialing：模拟信号时代的端口扫描

端口扫描 是网络攻击前的常见策略，目的是寻找可利用漏洞。（不过端口扫描不等于网络攻击）而模拟信号时代，也有类似的操作。

Wardialing 是 1980 年代活跃的一种技术，原理是机器自动穷举拨号，尝试了解电话后的设备。比如 电话应答机 会在无人接听时，播放「你好，我是 gledos，我现在不在家。可以给我留言，我会尽快联系你。」这样电话所有者的名字就暴露了。

又或者电话线路连接到了设置为自动应答的传真机，拨号者就能听到传真机握手信号声音。不过 Wardialing 最主要的目的，还是寻找拨号上网不设防的 modem（猫，调制解调器），这样就能轻松黑掉一些电脑。不过攻击细节，维基上没有写……

后来随着 modem 的安全策略加强，以及拨号上网被取代，所以 Wardialing 也就消失了。不过 Wi-Fi 时期，也出现了类似的情况。有人开着汽车，用设备扫描附近的 Wi-Fi 设备，这被叫做 Wardriving。

Telegram announces Search Filters

With the help of the Search Filters option, users can now filter search results by type. They can do that by using the new tabs: Media, Links, Files and others. Searches can be done based on the particular time period like by typing in the date or even “Yesterday”. If users type in the name of a person, group, channel or bot, an extra filter will be applied to the searches.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options.

What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
