Other research that will be presented in Financial Cryptography 2016 entitled "The Bitcoin Brain Drain" will discuss some things, such as how many brain wallets are in the blockchain today, and how many have been burglarized and stolen. Castellucci and some of its colleagues found 884 active wallets in September 2011 up to August 2015 and had received as many as 1,806 BTC (about $ 100 thousand). They are not the first to find this case. All but the 21 wallets have been stolen within 24 hours even in minutes. This shows the technique described in this study is a technique that is commonly used.
If you use a brain wallet, then you should review your wallet security level, even if necessary, move it to a safer wallet.

There are many ways in which a hacker can infiltrate or get into anything that is online. It is up to us to make the necessary precautions in order to at least minimize the risk of being the victim of such criminal activities. Also, online wallet services should make sure they are a step ahead of the hackers in terms of looking at possible loopholes in the site security.
can they hack into our wallet. There are many professional hackers out there. What are the chances? Also what is the safest way to safeguard ourself?
I don't think that there can be any hacker , who can hack Bitcoin wallet .If suppose someone hacked your wallet ( of blockchain ) then still he need to verify your account with email IP change link .
So he needed to hack the Gmail account also .
But suppose anyone get success to hack.the both two then still he can't use the Bitcoin until he will cross secondary password , which is the main password to make the transaction successful .
And as in the blockchain there is no option for the reset password , so there is no chance to hack.the wallet at all .
But if you are going to share all of your details to anyone or you are using third-party wallet then I am.sure that your money is at risk and anyone can steal.your money .
It is always perilous to make a contract via online. I think you should embrace it. 
yes, it can. there are online wallets and offline wallets.
online wallets gets hacked by hackers by compromising server. while offline wallets can get hacked by virus/trojan and this can lead to compelte losss of bitcoins.
the best option is keep the wallet offline., there are hardware wallets available., if you really need something very secure., then hardware wallets is the only option for now.,

Online wallet including a wallet that is vulnrable to hack especially if you use a wallet online that is not so famous?Make sure you add pin or 2fa (google auth, etc) so your wallet will be very safe. Even I doubt hackers can hack them
The most recent hacking incident right now is MEW. There are a lot of phishing site that when you click it and you enter your private key it automatically copied by their computer. And in a blink your MEW is already hacked. Don't easily click the link that you see better to save the url of the MEW.

It might also be a good idea to store your coins in a few different wallets, just in case one wallet for whatever reason is compromised.
That's good mate, storing your bitcoins at different wallet can prevent hackers from initiating and attack for your bitcoins. If ever there is a certaim possibilities and you see signs of hack attemps you can really have to generate and offline wallet just to store your bitcoin amounts.

Some hackers may have the ability to hack in your wallet most specially if you do not have multiple wallets wherein it could make you're bitcoin safer than ever. Having a very unique and strong password may help you avoid getting hacked. And worry less because they can only break into our bitcoin if they have excessive knowledge on how to hack it using their computers.

My experience says it can be, but if your question can get into the account. This is already the protection of every user on his computer.
At this time, an attempt is being made to crack my server password in order to get all the monetary data. But there are very few chances to succeed. And if succeed then everything will be lost. I'm also looking for more information about how to protect a server that contains a bitcoin wallet.

It is is possible if you haven't secured enough your wallet, or if your password or/and email get hacked or stolen. You need to secure your wallet and link it to your phone if you are using the online wallets and choose complicated passwords, and of course store your private key

One other topic I did not addressed (directly) above is that there are multiple vectors of attack (various ways hackers ccould get in).
A strong password helps a lot (but not of yoru computer has a keystroke logger, everyone's nightmare...)
A hardware wallet with good password and 2FA is good. Don't lose it! And keep the seed words hidden away securely!
Some online wallets are apparently better than others...
Access by others to your computer is another possible threat...

I think you have to make a good passwords. and you need extra security fow your wallet.
It was possible indeed, there's a lot of ways.
We have to put extra-security measure on our wallet, even it was online or offline wallet,
1. Enable two-factor authentication
2. Encrypting your wallet or your smartphone
3. Use strong password, it must contain letters, numbers, punctuation marks and must be at least 16 characters long
4. Always use a VPN
Rule of thumb's : don't' put all your eggs in one basket.

Hackers can simulate crack, but it requires a large amount of computation, quantum computer has been realized for example can crack the bitcoin wallet, but he won't be used in the above, he has a more important role. So you can rest assured that hackers generally steal your private key and information to steal your bitcoins 
Always try to private key is secure.But there are many expert hacker can hacked wallet.

there is no simple answer to the first part of your question. there are lots of different types of wallets and each type has multiple wallets. it is simpler for some to get hacked (like web wallets) while it is hard or even impossible for others to get hacked (eg. desktop and paper wallet).
as for the second part, just learn what a cold storage is. how to install a wallet offline and how to spend from an offline wallet and you are safe.
