GitHub Reacts to Growing Cryptocurrency Mining Attacks Using GitHub Actions

GitHub Reacts to Growing Cryptocurrency Mining Attacks Using GitHub Actions

As the market capitalization of cryptocurrency surged from $190 billion in January of 2020 to $2 trillion in April of 2021, it s become profitable for bad actors to make a full time job of attacking the free tiers of platform-as-a-service providers.
Chartier describes how an attacker can abuse GitHub Actions
cron feature to create new commits every hour with the aim to mine cryptocurrencies.
Because developers can run arbitrary code on our servers, they often violate our terms of service to run cryptocurrency miners as a build step for their websites.
According to Chartier, one strategy to reduce the chances of being detected that is becoming popular is using a headless browser for these attacks. ....

After cryptocurrency prices soared this week amid hype leading up to Coinbase’s direct listing, the market took a nosedive over the weekend. Bitcoin prices tanked by roughly 14% in 24 hours, from $61,530 to $52,829, the token’s biggest one-day drop since February, before rebounding slightly, according to the cryptoasset price-tracking site CoinMarketCap.

Prices of other popular cryptocurrencies plunged as well. Ether, which is second only to Bitcoin, saw its prices fall in 24 hours by about 17%, from $2,417 to $2,011. By Sunday evening, these tokens had somewhat recouped their losses, with Bitcoin and Ether down by roughly 9% and 8% respectively in the last 24 hours. During this so-called flash crash, cryptocurrency liquidations totaled roughly $10 billion, according to data from the crypto industry tracker Bybt. ....

"Data Access Control in Cloud Computing: Flexible and Receiver Extendab" by Jianchang Lai, Fuchun Guo et al.

Abstract
Broadcast encryption provides a promising technique of data access control for specified users in cloud computing. A data uploader can generate a ciphertext for a set of chosen users such that only the intended users are able to learn the data content. However, with the rapidly increasing of collaboration between users, it is desired to extend the receiver set to grant the decryption right for more users. The existing broadcast encryption systems cannot be capable for this scenario. In this paper, we first take this problem into consideration and give a solution. We take the merits of identity-based cryptosystem and propose a notion of EIBBE: a flexible data access control with receiver extendable for cloud computing based on broadcast encryption. It allows the authorized receiver to extend the receiver set S stated in the ciphertext by adding a new receiver set $S $ without re-encryption. Both the users in S and $S $ can obtain the data successfully. The maximum numb ....
