Why no motion of all coins from the hot wallets to cold, as a security precaution?
Has this been done?
This would be the first move to make if keys are compromised.

Todays message from Cryptopia Discord server:

Quote
Update from Managing Director of Cryptopia Exchange.
The co-founders, shareholders, executive and the entire Cryptopia Team appreciate the support that is being demonstrated here.
We cannot even consider re-opening the exchange while the investigation is in progress.
To even consider doing so would be totally irresponsible of us as it could likely make the way clear for further attacks and even more damage.
Please have patience and faith. We will continue to update everyone as and when we can. Take no notice of the armchair experts.

Actually a very responsible thing would be to allow read-only access, so that customers may take snapshots of their accounts.

If we think about it, whichever wallet was compromised would be emptied; for example why would the hacker get 1000 ETH if the wallet had 2000 ETH?
So what's stolen is stolen. I don't think it's possible to hack a new wallet while the exchange is not operating.

You would think in these days of all these new computer programming languages and AI that batch files could be run of each user's remaining balances, and a text file dump of that information be given to each person upon a log in.    Maybe in five years, or maybe people in general are just too uncaring or lazy of think of that and create it.

Any wallet/coin could possibly be compromised.
The second (the very second) you know that unauthorized TX have been sent you immediately shift funds to new privkeys as fast as their block chains can move.

Next you inform and sign where/howmany COINS you still have in secured custody.

Dead simple.

Before Christmas Cryptpoia sent out a blanket email stating that they had been hacked by 100+ alt coins (via a 51 % attack) and were closing those markets.
<snip>

xtraely and lafu and anyone else claiming to be representatives of Cryptopia definitely aren't because they would have been instructed not to make any statements while a criminal investigation is on going.


Neither Lafu nor myself are employees of Cryptopia. Nor are we authorized to make any statements on their behalf.  There is no official representation of Cryptopia on Bitcointalk as they only consider discord and twitter as official media channels.

As a client of the exchange I probably have more $ at risk than most.

You are correct that their staff have instructed not to make any statements. Most are on leave as the offices are considered a crime scene.


The other incidents last year that you mentioned are different.

A 51% attack by definition is a blockchain based attack. https://www.investopedia.com/terms/1/51-attack.asp It means the blockchain has been exploited and fraudulent transactions by a single attacker have caused the genuinely mined transactions to be discarded through chain re-organisation and orphaned. Some reputable devs have re-embused their customers that have been affected by a blockchain 51% attack.

I explained how such an attack works here: https://bitcointalk.org/index.php?topic=5035336.msg46025953#msg46025953

Quote
In May Bittrex was the victim of a 51% double spend attack on the Bitcoin Gold network. The Bitcoin Gold developers only offered to partially compensate Bittrex for the losses and Bittrex chose to delist Bitcoin Gold instead.

A coin network that allows a 51% attack double spend happen is neither decentralized nor immutable. Both of which are essential for a trustless network.

Many coins have changed from POW to Hybrid, POS or a more complex algo or discontinued because they are unable to prevent attacks on the coin network.

In regards to 51% attack please read https://bitcointalk.org/index.php?topic=494708.msg48633011#msg48633011
One day or initial wave of hacking is on devs.
10 days of hacking is on exchange.


Do you agree?

Actually it was on the customers.
Lost coins & Lost listing.

[which in hindsight is not a bad deal]

P.S.: Not making fun of your loss just pointing out the facts. I myself have had ~0.35 BTC in alts, BTC and LTC in topia when they went dark.

I don't understand why hasn't the community found out if Cryptopia's BTC wallets have been emptied as well or not.

I hadn't deposited or withdrew any BTC recently and I don't think I can find my last transaction with Cryptopia and track it, but I'll try it.
Wouldn't someone else have it traced and found their BTC addresses though?

Okay I think I found the Cryptopia's BTC wallet. My deposit there is kinda old and I can't recall 100% if it's the address I deposited was Cryptopia's or another exchange's, but I traced the movement and since the wallet's movements stopped on 14th January I'm 99% sure it's Cryptopia's.

This is their wallet: 3ALZ4ALw2T4jebXXUy8GMv2rLB7JpFL1JD

After many hops between 1-use addresses, I find a big amount of funds consecrated here: 12YBZCaPe45LFbvgYWP5AVm3pvZTtHTiNY
This was a new address created on 13th January.
It seems that after gathering BTC from different Cryptopia's wallets, summing 392.31 BTC, they sent a "test" transaction of 3 BTC on 14th January and 10 minutes later they sent all the amount to the same address.

From that point on, it seems like the funds were split to multiple addresses, probably many of which are exchanges.

Your thoughts? Anything I missed maybe?

I can provide transactions towards my cryptopia deposit address if some1 is interested. now that address is empty.

if you're right, other 14M$ in BTC have been stolen? I had 99% of my funds in BTC.

I think bankruptcy is right out there.

The $14M in BitCoin above and this $13M from ETH (tokens) listed on this page: https://www.reddit.com/r/Cryptopia/comments/ag75rs/cryptopia_hack_analysis_min_13000000_stolen/ plus a few other cryptos ( LTC $1M https://bitcointalk.org/index.php?topic=5097916.msg49253290#msg49253290 ) - ( not to mention any other Coin not listed yet) we're looking at $28M confirmed and probably ~ $30M all up.

Just an FYI - that's 23 million New Zealand dollars, or, $16M US$

Quote
Analysis of what happened has been published by a blockchain software company based in New York called Elementus whose analyst, Max Galta, estimated the unauthorised transfers were valued about US$16m (NZ23m).

(Try to be a bit clearer when quoting please)

Further reading on those $16M worth of Tokens stolen can be found here: https://elementus.io/blog/cryptopia-hack-transparency/

https://www.reddit.com/r/Cryptopia/comments/aib9ic/on_the_hack/ - Read this.

"After Cryptopia discovered the hack, they watched the funds continue to flow out of their wallets for four more days, seemingly powerless to stop it. As these wallets were not smart contracts, there should have been no technical complications preventing Cryptopia from securing the funds. The only plausible explanation for Cryptopia's inaction is that they no longer had access to their own wallets."
