@gentlemand warned a few days ago about the hacked of Albits, It is already included in the 2020 list, since that day.

Now some details of the stolen coins have been published:

Quote

An update on the company's website now indicates that "fortunately a good part of the coins were kept on cold storage" and that it will issue partial refunds, not having the wherewithal to fully compensate users.

The cryptocurrencies taken in the hack are now listed as:

Bitcoin (BTC): 6,929 lost out of 14,782 held
Ether (ETH): 23,210 lost out of 32,262
Pirate Chain (ARRR): 3,924,082 lost out of 9,619,754
Verus Coin (VRSC): 414,154 lost out of 852,726
Komodo (KMD): 1,066 lost out of 48,015

The site indicates that users who saw losses must apply for their partial refunds. The bitcoin and ether stolen are valued at around $63,000 at press time.

Someone should probably just keep a thread with all the hacks in alphabetical order so it can be scanned.

I have no doubt real hackers try their hardest to steal coins from exchanges, but you'd think that in such a tech-oriented business these exchanges would know a thing or two about security.

I'm sure most 'hacks' are the owners stealing but one of the biggest of all was Coincheck and that hack was entirely down to them keeping everything that was taken in a hot wallet. They had the free and fully integrated option of multi sig but didn't even do that, let alone pay up to $80 for a Trezor that would've saved them a few hundred million dollars.

Here's a fresh one - https://twitter.com/altsbit/status/1225319347687653377

Note the wording - 'A small part of the funds are safe on cold wallets.'

That feels like the wrong way round.

The question is, are they really that dumb enough or just simply making this as a cover up into their inside job? Why they cant really just consider on putting most of funds on cold storages?

I dont really buy that kind of words from them.Im not that familiar with that Altsbit name though but this start of the year with another exchange been hacked then it isnt really already
a surprising news.Wondering on whose would be the next on line.?

Going through this exchange hack list, quite really sad.
Let's avoid storing funds in exchanges, exchanges should solely be for trading, funds should be stored in non-custodian wallet. Fortunately some good wallets support Multi-assets and exchanges, few like exodus, trust, atomic.

More coins have likely been lost in users' own wallets than at exchanges. For people that aren't highly knowledgeable, I think storing coins on a reputable, regulated exchange is preferable. Of course, most of the coins over the years have been lost by highly knowledgeable people - early users. Storing your coins yourself also involves physical security. Protecting your storage device, as cryptocurrency-specific storage devices have notoriously poor physical security. And of course protecting your seed.

It causes me anxiety to do so, I kid you not.

It's true, you only have this feeling when you really know what can happen at any time.
And even if their exchange is not pirated, they can also close it and disappear forever.

Bitspark Shuts Down Amid Restructuring, Coronavirus and Protests

Quote

Hong Kong-based blockchain remittance startup Bitspark has abruptly announced its closure, citing internal restructuring issues.

On Feb. 3, Bitspark co-founder and CEO George Harrap officially announced the platform’s plans to shut down its services on March 4, 2020.

According to the statement, Bitspark users will be able to withdraw their cryptocurrencies from Feb. 3 to March 4 as the platform’s functionality will stay intact over the period. After March 4, account logins will be disabled for a period of 90 days, with users being able to withdraw their funds via Bitspark customer support, the announcement reads.

Jesus, I've been around long enough to know there were quite a few exchanges that got hacked but I apparently missed this thread and didn't realize there were so many.

Sometimes I've wondered whether some of these so-called hacks were real, or if they were cases of exchange employees pulling inside jobs and stealing funds. That's what happened in Cryptsy's case if I'm not mistaken, and in any case if you're an exchange, claiming you got hacked provides the perfect cover for an exit scam. I have no doubt real hackers try their hardest to steal coins from exchanges, but you'd think that in such a tech-oriented business these exchanges would know a thing or two about security.

I don't do much trading, but I do still buy some altcoins occasionally and even though I trust the exchange I typically use, there's no way in hell I'd keep coins on it for more than a day. It causes me anxiety to do so, I kid you not.

Cryptocompare exchange review
https://www.cryptocompare.com/media/36639870/cryptocompare_exchange_review_2019_11.pdf

The Cryptocompare portal has some interesting reports where they explain how they evaluate the exchanges, in the portal you can select the list of exchanges by centralized, decentralized, by country and some more variables to order the presentation to your liking.

The reports are quite extensive, but they provide a lot of data, reading them will not save us from possible hackers in an exchange, with the information they present we have an "approximate" idea of the veracity of volume or liquidity of the exchange.

If you wish to save yourself from a possible hack and losing funds you have on some exchange you can do only two things, withdraw your funds when you finish with trading or use a decentralized exchange. Withdrawing funds after trading can be expensive, fees are high! Decentralized exchanges are slow with their low volumes. What is better to do, risking with leaving funds on an exchange, or being slow on dex but safe is a question for each of us.

The popular blockchain analytics company, ChainAnalysis, recently posted a review of how 2019 related to previous years in terms of cryptocurrency exchange hacks. The data reveals an increased number of attacks, but less stolen money compared to 2018.

Very complete report, the final part refers to the techniques used to steal the funds and how they prepare the strategy for hacking:

I thought about including scams or vulnerabilities of the wallets, but I think it is better to focus the thread only in the exchanges, but if there is any important news on this subject, it can also be published in the thread.

But this type of news is published quickly in several sections of the forum.
Anyway thanks for your suggestion.

The Concierge of Crypto

One of your posts (second one) includes only Bitcoin Core as software. I think some other wallets could be included as part of that list, namely Electrum, latest version, downloaded from official website, verified signature and file hash. Also Electrum for Android since it's the same except for mobile phones / tablets. Might as well mention Bitcoin Wallet for Android.

With a note that, do not download any updates except from official website or Google Play store. There was a recent phishing attempt, but it has been fixed by preventing showing links in server messages. Still, no one would have gotten their coins stolen if they only checked the official websites and not clicked on a pop up message.

I want extend a thank you to OP from the crypto community on his work. We need to create more awareness on what has happened and how it happened and what we need to do to prevent it from happening in the future. Will be sharing this thread to my friends so that they will know the real values rather than just rumors.

South Korean crypto exchange Upbit has lost cryptocurrency worth $49 million, the exchange has confirmed.

Upbit’s CEO said in a blog post at 9:00 UTC on Wednesday that an abnormal transaction from its wallets had resulted in the outflow of 342,000 ether (ETH) earlier today.

We haven't finished the year and we have another exchange hacked.

Surprisingly the number of exchange hacked on 2019. Seemed like it was worst year for these exchange since they've lost not just money but the trust of the people. I am not already trading with other platforms only those who are at the top exchanges since most secured exchange are on top. But we haven't secured our assets in exchange because anytime it will be hacked even they are the safeat exchange ever.
