Side-channel attacks explained: everything you need to know

In this blog post, we take an in-depth look at the world of side-channel attacks.

We describe how side-channel attacks work and detail some of the most common attack methodologies. We also explore differential power analysis (DPA), an extremely powerful side-channel attack capable of obtaining and analyzing statistical measurements across multiple operations. In addition, we provide a walkthrough of a DPA attack and explain how different countermeasures with varying levels of effectiveness can be used to prevent side-channel attacks.

MACsec Explained: From A to Z

For end-to-end security of data, it needs to be secured when at rest (processed or stored in a device) and when in motion (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides the foundation upon which all data security is built. Similarly, for data in motion, security anchored in hardware at the foundational communication layer provides that basis of trust, and that’s where MACsec enters the picture.

World Cup Cryptocurrency Ring Bust in China

Every four years, the FIFA World Cup is a chance for people to come together and celebrate the beautiful game, and for some lucky enough to be born in a country with a successful soccer team, cheer on their nation’s team in a quest for glory. For some, however, the World Cup is also a way to make some money on the side, as evidenced by an illegal cryptocurrency gambling ring worth 10 billion yuan (US$1.5 billion) in bets that was recently busted by Chinese police.

Police in southern Guangdong province said in an online statement on the 12th of July, 2018 that they apprehended six major suspects of the ring, froze about five million yuan (around US$733,000) in their bank accounts, and seized around 10 million yuan worth of their cryptocurrencies.

The gambling platform ran in a part of the web that is not indexed by traditional search engines, and only accepted Bitcoin, Ethereum, and Litecoin. During the eight months of the gambling ring’s existence, the site attracted 330,000 registered users from numerous countries, and had over 8,000 agents who earned commissions for recruiting new members through a pyramid scheme, according to the police.

The police statement goes on to explain that, thanks to the lack of effective regulation on cryptocurrencies, the gambling syndicate exploited that loophole to make huge profits.

The cryptocurrency ring bust is but the latest development in the Chinese government’s efforts to securitize cryptocurrency. Last September, the government shut down all local crypto exchanges and banned Initial Coin Offerings (ICO), a form of crowdsourced fundraising involving cryptocurrencies, amid fears they could create financial instability. In late July, 2018, the Chinese central bank announced that the yuan-bitcoin trading pair has dropped to less than one percent of the world’s total bitcoin trading, according to Xinhua.

Recent Developments in China’s Crackdown on Gambling

Gambling in the World Cup is a major venture in China, but the government has been taking several steps to crack down on the practice. Aside from two officially sanctioned lotteries, gambling is largely illegal in China.

In a separate statement, Guangdong police have stated that they arrested a total of 540 suspects from over 20 gambling rings, and frozen 260 million yuan (around US$38 million) related to illegal gambling, in a special campaign to crack down on World Cup gambling. However, they have noted that the use of cryptocurrency “is most representative of the new-type of online football gambling so far.”

The Bottom Line

While busting gambling rings, especially with regards to the FIFA World Cup, is nothing new to the police in China, the use of cryptocurrencies worth hundreds of millions of dollars is another sign that while the lack of regulation has allowed cryptocurrencies to flourish, it has also allowed them to be used in an illicit, underhanded manner. While the Chinese government and police and continue to bust these rings, more preventative measures might stop cryptocurrencies from being used in criminal activities.
