Unknown Copycat Using Armada Collective Name for DDoS-for-Bitcoin Extortions

After the success of DDoSing outfits like DD4BC and Armada Collective, an unknown copycat that's using the Armada Collective name but asking for astronomical payments has appeared.

A report from Recorded Future, a real-time threat intelligence protection company, shows that DDoS-for-Bitcoin extortion schemes are here to stay, with more and more attacks being launched solely for this reason.
DD4BC have launched a new type of extortion scheme

This trend can be tracked down to an Akamai report released over the summer that documented the actions of a hacking group known as DD4BC (DDoS 4 Bitcoin). This group launched DDoS attacks on companies around the world, requesting small payments in Bitcoin for each target.

The group's scheme was a simple one. They would send threatening emails to business owners, saying they would launch powerful DDoS attacks if a ransom was not paid in due time to a specific Bitcoin wallet. To prove their point, a small 15-minute DDoS was launched to showcase their capabilities.

DD4BC's scheme proved to be extremely lucrative and allowed them to rack up Bitcoin over the past year in over 140 DDoS attacks.

The group was active since late 2014 and suddenly stopped its activity after the Akamai report was released, probably to avoid getting caught by law enforcement authorities alerted to their scheme.
Enter Armada Collective

Soon after, the first DD4BC copycat arose, in the form of the Armada Collective hackers, carrying out DDoS attacks on small businesses in Switzerland.

They then expanded to email providers, and their name became known around the world in the famous ProtonMail incident. The incident is very well documented in one of our previous stories, but we'll give you a small summary.

Basically, Armada Collective followed the DD4BC regular tactics, sending an email and launching a small 10-15 Gbps DDoS attack on ProtonMail.

Bitcoin startup BitX rings in funding from Venturra Capital

Singapore-based bitcoin startup BitX has raised a round of funding from Venturra Capital, it announced today.

BitX previously raised US$4 million for its series A round in July. That round was led by South African media conglomerate Naspers and joined by investors like the Digital Currency Group, a bitcoin-focused investor founded by cryptocurrency stalwart Barry Silbert.

The amount is undisclosed at the moment. “It’s a substantial amount and what we believe to be the first substantial investment from a Southeast Asian VC into a bitcoin company,” Marcus Swanepoel, CEO and co-founder of BitX, tells Tech in Asia. He does share that Naspers is still the startup’s largest institutional investor.

The funding will allow BitX to speed up a number of activities it started with its series A funding. These include recruitment, product development, and entering new markets. “We’ve seen some really strong growth over the past three months so having additional cash to help drive these initiatives and ultimately result in an even better customer experience is very useful,” Marcus says. He confirms that the funding is 100 percent available to the company.

Venturra, a US$150 million fund for businesses in Indonesia and Southeast Asia, debuted a few months ago and has since announced a number of investments like Indonesian beauty ecommerce site Sociolla and Malaysian services startup Kaodim. Marcus says the VC is an important partner for BitX for its plans, especially when it comes to building ecosystems. “This is where their relationships and access to companies that can help us enable these ecosystems is key,” he says. Additionally, the VC has valuable expertise in helping BitX localize its services for Indonesia, a market it entered in early 2015.

“BitX has an exceptional team that combines deep technical expertise and commercial acumen. They have proven they can build innovative products and strong traction in a rapidly emerging industry,” Stefan Jung, co-founder and managing partner at Venturra Capital, says in a statement.

Cyber Extortion, DDoS-For-Bitcoin Campaigns Rise '

Now that the model is proven, more cyber-extortionists are entering the scene, stealing their predecessors' ideas and even their names.

Whether it be via DDoS, doxing threats, or ransomware, attackers extorting victims for cash via electronic means is growing, and Bitcoin may be partly to blame for the increase, according to researchers at Recorded Future.

"Bitcoin attracted more miscreants to the space," says Tyler Bradshaw, solutions engineer for Recorded Future. Because it's a relatively new, the unregulated currency allows extortionists to accept payments anonymously.

While ransomware operators are generally indiscriminate about targets, go after individuals, and request small ransoms of 1 to 2 BTC (currently approximately $349 to $698), DDoS extortionists take the opposite approach.

Last year, the threat group DD4BC (short for "DDoS for Bitcoin") first emerged. DD4BC's modus operandi was to threaten a company with a major distributed denial of service -- on the magnitude of 400-500 Gbps -- prove it could compromise the network by carrying out a low-level warning attack of roughly 10-20 Gbps, and demand a payment to prevent a large-scale DDoS. According to Recorded Future, DD4BC has attacked over 140 companies in this way.

According to a report by researchers at Akamai’s Prolexic Security Engineering and Research Team (PLXsert) released in September, the group first targeted online gaming and online currency exchanges -- which would be reluctant to request help from law enforcement. They then shifted attention to financial services companies, tweaking the attack to include a threat of publicly embarrasing the company by revealing, via social media, the company had been DDoSed.

DD4BC's ransom demands ranged from 10 BTC to as much as 200 BTC (currently $3,940 to $78,788), often starting low and increasing the price the longer the victim failed to pay up.

DD4BC did not actually seem to be capable of carrying out the 400-500 Gbps-scale attack they threatened. The worst Akamai detected was 56 Gbps. Yet, the threats and warning attacks were enough to convince targets to pay the ransom.

As Akamai PLXsert wrote in its September report:
