Coinvault, the court case

Today, after almost 3 years of waiting, it was finally the day of the trial. In the Netherlands, where the whole case took place, the hearings are open to the public. Meaning anyone who is interested can visit. And it was quite busy.

Bitcoin Blackmail by Snail Mail Preys on Those with Guilty Conscience

KrebsOnSecurity heard from a reader whose friend recently received a remarkably customized extortion letter via snail mail that threatened to tell the recipient’s wife about his supposed extramarital affairs unless he paid $3,600 in bitcoin. The friend said he had nothing to hide and suspects this is part of a random but well-crafted campaign to prey on men who may have a guilty conscience.

Skyrocketing Bitcoin Fees Hit Carders in Wallet

Critics of unregulated virtual currencies like Bitcoin have long argued that the core utility of these payment systems lies in facilitating illicit commerce, such as buying drugs or stolen credit cards and identities. But recent spikes in the price of Bitcoin — and the fees associated with moving funds into and out of it — have conspired to make Bitcoin a less useful and desirable payment method for many crooks engaged in these activities.

Mirai IoT Botnet Co-Authors Plead Guilty

The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).

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.

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.”

IoT Devices as Proxies for Cybercrime

Multiple stories published here over the past few weeks have examined the disruptive power of hacked “Internet of Things” (IoT) devices such as routers, IP cameras and digital video recorders. This post looks at how crooks are using hacked IoT devices as proxies to hide their true location online as they engage in a variety of other types of cybercriminal activity — from frequenting underground forums to credit card and tax refund fraud.

TeamXRat: Brazilian cybercrime meets ransomware

We discovered a new variant of a Brazilian-made ransomware, that is being used to infect local companies and hospitals, directly affecting innocent people, encrypting their files and asking to pay the ransom.

Israeli Online Attack Service ‘vDOS’ Earned $600,000 in Two Years

vDOS — a so-called “booter” service that has earned in excess of $600,000 over the past two years helping customers coordinate more than 150,000 so-called distributed denial-of-service (DDoS) attacks designed to knock Web sites offline — has been massively hacked, spilling secrets about tens of thousands of paying customers and their targets.

The vDOS database, obtained by KrebsOnSecurity.com at the end of July 2016, points to two young men in Israel as the principle owners and masterminds of the attack service, with support services coming from several young hackers in the United States.
