Ethereum Parity Bug Destroys Over $250 Million In Tokens


If you are into cryptocurrency or blockchain at all, you will have heard about the Ethereum Parity Bug that has basically thrown $280 Million value or more of Ethereum tokens in the bin.

Ethereum Parity Bug Destroys Over $250 Million In Tokens


It’s a bit of a mess really, and a mistake by the developers who introduced it after fixing another bug back in July to do with multisig wallets (wallets which multiple people have to agree to transactions).

You can see the thread on Github here: anyone can kill your contract #6995

There’s a lot of hair-pulling among Ethereum alt-coin hoarders today – after a programming blunder in Parity’s wallet software let one person bin $280m of the digital currency belonging to scores of strangers, probably permanently.

Parity, which was set up by Ethereum core developer Gavin Woods, admitted today that a user calling themselves devops199 had “accidentally” triggered a bug in its multi-signature wallets that hold Ethereum coins. As a result, wallets created after July 20 are now locked down and inaccessible, quite possibly permanently, thus nuking $90m of Woods’ own savings.

Multi-signature wallets mean more than one person has to sign off on a transaction before funds are moved, and are popular with companies and investment groups looking to protect their assets. Unfortunately, Parity’s technology is seriously flawed: in July a hacker managed to exploit errors in the multi-signature code to steal about $30m in Ethereum.

In response to that cockup, rity updated its wallet software to address the vulnerability, and rolled out a new version. However, that update contained another disastrous bug, one that would lock people out of their wallets. It was set off by devops199 on Monday, affecting anyone who had installed the new code since its release.


So far it seems this Ethereum Parity Bug has affected 573 wallets, which is quite a lot – shown on the tool to check if you were affected:

Parity MultiSig Freeze Tool

This includes the loss of $90 Million or so owned by the Parity wallet owner and Etherum core developer Gavin Woods.

“That code still contained another issue – it was possible to turn the Parity Wallet library contract into a regular multi-sig wallet and become an owner of it by calling the initWallet function,” Parity’s advisory stated.

“It would seem that issue was triggered accidentally 6th Nov 2017 02:33:47 PM +UTC and subsequently a user suicided the library-turned-into-wallet, wiping out the library code which in turn rendered all multi-sig contracts unusable since their logic (any state-modifying function) was inside the library.”

In a series of posts on GitHub, devops199 said they were a newbie to the crypto-currency system, and had created a multi-signature wallet in a way the software did not expect. When devops199 tried to delete the buggy money pouch, it bafflingly locked down all multi-signature Parity wallets created after the last software update.

A full list of 70-odd affected wallets has been uploaded to Pastebin.

Parity has confirmed the above sequence of events leading to this week’s catastrophe with The Register. So far there’s no response on whether it will be possible to unlock the wallets, or if there are any plans to recover punters’ digital dosh. We’ll post more information when it becomes available.

That’s a lot of money that just went in the bin and I’d guess a whole bunch of angry people just went from being millionaires to nothing. I hope those with a lot of coins, who suffered a loss, didn’t invest a lot of their own real World money to get them.

That would be really painful.

It’s also interesting to note that following this the value of Ethereum has actually gone up, maybe because there’s less in circulation now? Or just more people found out about it.

There’s also no real way to fix Ethereum Parity Bug unless Ethereum forks back to before the tokens got wiped out by the bug, which seems pretty unlikely. Also Vitalik has been pretty quiet about the whole thing only tweeting this.

The last crypto thing that most people didn’t know about was that most Bitcoin vendors are actually compromising the supposed Anonymity of using Cryptocurrencies.

Malaysia Telco Hack – Corporations Spill 46 Million Records


The Malaysia Telco Hack has been blowing up in the news with over 46 Million Records being leaked including IMEI numbers, SIM card details, serial numbers and home addresses.

Malaysia Telco Hack - Corporations Spill 46 Million Records


This is an interesting one for me as I live in Malaysia, so this Malaysia Telco Hack was big news over here, especially seen as though from the numbers it looks to affect pretty much every single person in the country (and many more than once with a popular of 31 million).

It’s also a pretty big leak, even on the global scale with the recent large with other recent high-profile cases like Taringa hack being 27 million, Equifax hack at 143 Million or more and Time Warner Cable hack with a paltry 4 Million.

The personal data of millions of Malaysians has been swiped by hackers who raided government servers and databases at a dozen telcos in the southeast Asia nation.

Information on 46.2 million cellphone accounts was slurped from Malaysians telecoms providers. To put that in context, the population of Malaysia is 31.2 million; obviously, some people have more than one number.

The stolen telco records include people’s mobile phone numbers, SIM card details, device serial numbers, and home addresses, all of which are useful to identity thieves and scammers. Some 80,000 medical records were also accessed during the hacking spree, and government websites as well as Jobstreet.com were attacked and infiltrated, too, we’re told.

The Malaysian Communications and Multimedia Commission, along with the police, are probing the computer security breaches. DiGi.Com and Celcom Axiata are among the dozen compromised telcos assisting investigators.


The breach was first seen on LowYat.net a local technology forum, but the article was taken down very shortly afterwards by the Multimedia Commission of Malaysia (MCMC).

The data itself appeared on the darknet selling the files for an undisclosed amount of Bitcoin, which is a fairly normal thing to happen to leaked data although it seems the hack (or hacks?) took place some time in 2014.

The intrusions were first reported by Malaysian news site lowyat.net, which spotted, in the middle of last month, a mystery scumbag trying to flog the stolen data for Bitcoins.

Malaysian officials confirmed this week that nearly 50 million mobile phone account records were accessed by hackers unknown. The authorities also warned that people’s private data was stolen from the Malaysian Medical Council, the Malaysian Medical Association, the Academy of Medicine, the Malaysian Housing Loan Applications body, the Malaysian Dental Association, and the National Specialist Register of Malaysia.

It’s believed the systems were actually hacked as far back as 2014, The Star reported.

Incredible as it may seem there’s at least a couple of precedents for a huge chunk of the population of an entire country getting caught up in a database security breach.

Apart from telcos there appeared to be data from some other large Malaysian corporations including Jobstreet, the Malaysian Medical Council, Malaysian Housing Loan Applications, the Dental Association and some others.

And those were big too with the Jobstreet database alone having almost 17 Million rows of customer information including address and phone number for many people, which seemed to date back slightly further to 2012-2013.

The Malaysia Telco hack data included every major telco and MVNO in the country, Celcom, DiGi, Maxis, Umobile, Friendi, Tunetalk, Redtone, XOX, Altel, PLDT and EnablingAsia.

It’s very likely the data has been for sale for quite some time on the darknet markets, someone probably bought it cheaply as it’s quite old and exposed it by trying to make a quick buck on a clearnet forum.
