Bitcoin Payment Processor BIPS under DDoS Attack, Over $1m Stolen

Europe’s primary bitcoin payment processor for merchants and free online wallet service, BIPS, was the target of a major DDoS attack and subsequent theft in the past few days that saw 1,295 BTC (just over $1m on CoinDesk’s BPI) stolen. Kris Henriksen, BIPS’ CEO, said most of the missing funds were “from the company’s own holdings”. BIPS uses an algorithm, based on supply and demand, to work out the amount of bitcoins it needs to keep it in a ‘hot wallet’. The heist, however, was apparently not due to any vulnerability in the code itself. He also said merchants who had chosen to instantly convert their bitcoin to fiat currency bank accounts were not affected. Theft The Copenhagen, Denmark-based company was targeted on 15th November by a massive DDoS attack. Then on 17th November, it was followed up by a subsequent attack that disabled the site and “overloaded our managed switches and disconnected the iSCSI connection to the SAN on BIPS servers”. “Regrettably, despite several layers of protection, the attack caused vulnerability to the system, which has then enabled the attacker/s to gain access and compromise several wallets,” the company said in a written statement. BIPS believes the two attacks were connected, and at least the initial DDoS attack was “found to originate from Russia and neighboring countries”. The company moved fast to restore full merchant payment and transfer services by 19th November, but disabled all wallet functions in order to complete a full forensic analysis. Its help desk also went down for a few days, but was restored on 22nd November. Investigation Under BIPS’ privacy policy, it is not allowed to disclose users’ information to anyone, even the authorities. They will now set up a system for affected wallet users to voluntarily sign the required permission documents, to engage in a more thorough investigation with law enforcement to track down the culprits. Henriksen stressed that merchant processing “was restored very quickly, and if you had auto-convert on, there is nothing to worry about”. BIPS’ official statement on its site read: To protect the successful merchant processing business, BIPS has decided to temporarily close down its consumer wallet initiative. BIPS has been a target of a coordinated attack and subsequent security breached. Several consumer wallets have been compromised and BIPS will be contacting the affected users. As a consequence BIPS will temporarily close down the wallet initiative to focus on real-time merchant processing business which does not include storing of bitcoins. Subsequently BIPS will consider to reintroduce the wallet initiative with a re-architected security model. The consumer wallet initiative has not been BIPS’ core business and, as such, regrettably affecting several users has not affected BIPS merchant acquiring. All existing users will be asked to transfer bitcoins to other wallet solutions, and users affected by the security breach will be contacted. Restoration of merchant services did little to comfort individual wallet owners, though. On the Bitcoin Talk forum, several users voiced anger at the prospect of losing their funds, and what they saw as unclear statements from BIPS about exactly what had been stolen, from whom, and how much. One member even created a ‘bips.me potential lawsuit signup form’ for users to input their contact details and number of bitcoins missing, in an effort to prompt a negotiated solution. Though the attack and theft highlights problems that some online wallet services have faced with security, it is significant given BIPS’ comparatively large user base and prominence in the market. As well as online accounts, BIPS had also offered a paper wallet function for those wishing for a safer long-term storage solution.

AFP and RBA websites hit by DDoS attacks

The websites for the Australian Federal Police (AFP) and the Reserve Bank of Australia were hit overnight by distributed denial of service attacks claimed to be brought about by Indonesians angry over the leaks that reveal Australian Signals Directorate (ASD) had been tapping the phones of high ranking Indonesian government officials, including President Susilo Bambang Yudhoyono. The AFP’s website was for some time overnight but was restored this morning, with one Twitter user claiming responsibility for bringing the sites down using the hashtags #AnonymousIndonesia and #IndonesiaCyberArmy. The AFP said it was taking the attack “very seriously” but said that no sensitive information was hosted on the public-facing website. “The AFP website is not connected to AFP IT systems. The AFP website is not hosted by AFP ICT infrastructure. It is hosted by a third party hosting provider,” the AFP spokesperson said in a statement. The spokesperson said he was not at liberty to divulge the name of the hosting company. The AFP said the attacks were irresponsible and would not influence government policy. “Activities such as hacking, creating or propagating malicious viruses or participating in DDOS attacks are not harmless fun. They can result in serious long-term consequences for individuals, such as criminal convictions or jail time,” he said. “AFP Cyber Crime Operations identifies, investigates and prosecutes individuals or groups for offences committed against Australian critical infrastructure and information systems.” The RBA’s website was affected by the DDoS attacks, but a spokesperson for the RBA denied that the website had been brought down. “There has been no outage but the Bank’s website has been experiencing access delays for some users,” the spokesperson said. “The bank has DOS protection for its website, which has been effectively deployed. The bank’s website and systems remain secure.” The attacks come as Australia’s relationship with Indonesia continues to strain in the wake of the phone tapping revelations leaked earlier this week by former NSA contractor Edward Snowden. Prime Minister Tony Abbott is facing increasing pressure from the Indonesian government to explain the revelations.

Bitstamp Suffers Banking Software Issue and DDoS Attack

Bitstamp’s website has been experiencing a number of difficulties over the past couple of days. Yesterday, the Slovenia-based company experienced problems with the banking software it uses. A statement on the company’s blog and Facebook page reads: Dear Bitstamp clients, We are currently experiencing some problems with our banking software. As a result, deposits and withdrawals may be delayed. We expect this issue to be solved be resolved tomorrow or the next day. We kindly ask our customers with pending transfers to remain patient and refrain from submitting additional support tickets on the matter. We will announce as soon as this issue gets resolved. Thank you for your understanding. Best regards, The Bitstamp team With a tweet 19 hours ago stating: Bitstamp CEO Nejc Kodri? said the issue related to the company’s transaction log: “We were missing bank transaction log from Friday. Also sending transfers out was disrupted, but it now works.” This afternoon, the site suffered a DDoS attack. The last time CoinDesk was successfully able to access price data from Bitstamp was 14:05 (GMT). The site is still experiencing problems. Kodri? said his team is “still working on this” issue. Kodri? said the site hasn’t experienced any difficulties because of increased user traffic over the past couple of days, during which the bitcoin price has increased sharply. In fact, the entrepreneur said the site experienced a record number of visits yesterday with no problems. Source: http://www.coindesk.com/bitstamp-suffers-banking-software-issue-ddos-attack/

Radio Free Europe/Radio Liberty (RFE/RL) Targeted for DDoS attack

Radio Free Europe/Radio Liberty has been targeted in an Internet attack known as a distributed denial of service (DDoS). The attack has disrupted RFE/RL’s global multimedia news and information services intermittently since November 14. Nonetheless, its computer network was working on November 18 and broadcasts have continued normally. The attack has not prevented the public from accessing RFE/RL’s web pages. But it has slowed the ability of RFE/RL’s broadcasting services to upload fresh news stories, photographs, and video to the Internet. RFE/RL President Kevin Klose said information is still being gathered about the attack, but he confirmed that it is believed to be “targeted.” Klose said a decision was taken on November 18 to report on the attack in response to the needs of the broadcasters’ audiences, “who rely on RFE/RL reporting, and who themselves contend with countless obstacles to connect with us every day.” RFE/RL’s content-management system also supports Voice of America, Middle East Broadcasting, and the Office of Cuba Broadcasting. Those U.S. international media networks also have been adversely affected by the attacks but continue to operate. Klose described the attack as “stark evidence of the challenges that confront the free dissemination and exchange of information in this age.” A DDoS attack floods the target with fake requests that come from thousands or even millions of computers that have been compromised or infected with viruses or malware. RFE/RL experienced a more limited DDoS attack against its Belarusian language service in 2008. RFE/RL Director of Technology Luke Springer said the latest attack was discovered on November 14 when hardware for the international media organization’s computer network began receiving many times more requests than normal. At the peak of the attack, the RFE/RL network was receiving requests for data from hundreds of thousands of computers every second. Springer said that means there are probably more than 1 million malware-infected computers being directed by the attackers — most likely without the knowledge of the computer owners. Technical investigations show that nearly 80 percent of the computers sending out requests for data as part of the DDoS attack are in China and nearly 20 percent are in Russia. But Springer said those findings do not indicate who is responsible for the attack. Attempts to make technical changes that counter the attack have temporarily alleviated the problem. But Springer said the attackers also have been changing their methods, allowing them to continue disrupting services intermittently. Springer said the DDoS attack has not damaged RFE/RL’s network equipment. But he says that “filling up the Internet pipeline with so many bogus requests has caused a traffic jam.” RFE/RL is a private, nonprofit organization funded by a grant from the U.S. Congress.

New Zealand Couriers struck down by DDoS attack

The New Zealand Couriers website was the victim of a ‘denial of service’ botnet attack late last week, believed to be from overseas. The ‘denial of service’ attack, which took place on Thursday November 7, was specifically aimed at preventing access to www.nzcouriers.co.nz and the online tools hosted on this page, and required intensive and malicious effort by an unknown group. Revealed through a customer email sent out by the company, NZ Couriers wrote: “We have sorted out the issues caused by this attack for the most part. “But there are some important pieces of information we wanted to make you aware of: • You may experience a longer wait time than usual when contacting our call centre, due to more people doing things over the phone that they would usually do through our website. We would encourage you in the first instance to try using our online tools as usual before calling through to book a courier, buy product, or track an item. • The issue was caused by a malicious attack, but no one who visits our website is at any sort of risk – this is not related to viruses or anything along those lines. • Traffic to www.nzcouriers.co.nz has been restricted to New Zealand and Australian based companies – so if you have a customer outside of this region, or if your company runs an offshore system then they may not be able to access this website. If this occurs, we do have a way to resolve this – simply contact us on 0800 800 841 and we’ll get the details from you required to sort this out. Admitting that there may be “some lingering issues over the next few days,” NZ Couriers claims these are likely to be sorted out within the next week. “New Zealand Couriers apologises for this interruption of service and we will continue to do everything in our power to deliver the same great service you have come to expect from us,” the company email concluded.

Pro Afrikaans Action Group (Praag) under DDoS attack

Afrikaans language activist group Praag intends to lay criminal charges against people responsible for attacking its website, the group said on Thursday. Pro Afrikaans Action Group (Praag) founder Dan Roodt said the website and servers had been under a “distributed denial of service” (DDOS) attack, causing disruptions since Tuesday. He believed the attack was aimed at bankrupting Praag and its service provider through the consumption of bandwidth and damage to network infrastructure. “We are going to lay charges with the SA Police Service under the Electronic Communications and Transactions (ECT) Act 25 of 2002 for the DDOS attack against us, but also against those anonymous individuals slandering us on Facebook, social media, and in relation to potential advertisers on our site,” said Roodt. On Sunday, Rapport reported that Google had decided to stop channelling advertising to Praag, and this threatened the future of the website. Roodt told the paper that Praag made thousands of rands from advertising on its website, and would not be able to function without advertisers. He said Google told him that Afrikaans was not a recognised advertising language and it could channel advertisements only to the English version of the Praag website. Roodt, however, alleged that a woman who opposed Praag was behind the problem. He claimed the woman had started a “malicious and fanatical” Facebook group called “Speak Out Against the Website Praag”. In a letter she reportedly posted on the social media network, she accused Praag of being racist and of spreading hate speech, and shared the letter with companies she claimed were helping it spread this message by advertising on the website. On Thursday, Roodt said he had the backing of supporters to take on the attackers. “We will not be using the distasteful and underhanded techniques of our opponents but will be defending ourselves in an open, transparent and legal manner,” he said.
