Miners on the Rise

Over the last month alone, we have detected several large botnets designed to profit from concealed crypto mining. We have also observed growing numbers of attempts to install miners on servers owned by organizations. When these attempts are successful, the companies’ business processes suffer because data processing speeds fall substantially.

Satoshi Bomb

Let us discuss what defines the profitability of bitcoin mining, what principles for mining speed adaptation were initially embedded into it, and why these principles can lead to the failure of the cryptocurrency in the long run.

Jimmy Nukebot: from Neutrino with love

In one of our previous articles, we analyzed the NeutrinoPOS banker as an example of a constantly evolving malware family. A week after publication, this Neutrino modification delivered up a new malicious program classified by Kaspersky Lab as Trojan-Banker.Win32.Jimmy.

SambaCry is coming

Not long ago, news appeared online of a younger sibling for the sensational vulnerability EternalBlue. The story was about a new vulnerability for *nix-based systems – EternalRed (aka SambaCry). On May 30th our honeypots captured the first attack to make use of this particular vulnerability, but the payload in this exploit had nothing in common with the Trojan-Crypt that was EternalBlue and WannaCry.

Zcash, or the return of malicious miners

On 28 October, the cryptocurrency world saw the emergence of a new player, the Zcash (ZEC) cryptocurrency. Its developers have described it rather figuratively: “If Bitcoin is like HTTP for money, Zcash is HTTPS.” They continue by noting that “unlike Bitcoin, Zcash transactions can be shielded to hide the sender, the recipient and value of all transactions.”

Challenging CoinVault – it’s time to free those files

Some months ago we wrote a blog post about CoinVault. In that post we explained how we tore the malware apart in order to get to its original code and not the obfuscated one.

Blockchain Technology Abuse: Time to Think About Fixes

Kaspersky Lab and INTERPOL presented research on how blockchain-based cryptocurrencies could be abused through the pollution of public decentralized databases with arbitrary data.
