Criminals demand Bitcoin not to take down sites of companies with DDoS attack

The criminals demanded 10 bitcoins not to attack their victims, but the price of digital currency rose so fast that they had to reduce the amounts of extortion.

There are evil people everywhere and unfortunately the Internet is infested with people looking for the opportunity to apply scams and commit crimes. According to the security company Radware, groups specialized in extortion are sending e-mails with threats of DDoS attacks to companies, the group of criminals asks their victims to send Bitcoin Era so that they do not proceed with the attack.

In a DDoS (Distributed Denial of Service) attack which translated means „Denial of Distribution of Service“, criminals overload a server in order to make it inaccessible to any user over the internet. In this case the main target of these criminals are companies and their respective pages.

The intention is to generate an access overload, preventing customers or people from accessing the site.

Radware has published a security alert stating that during the last week of last year and the first week of this year its customers have received several e-mails with extortion threats.

In the e-mails the criminals threaten the victims with DDoS attacks. The companies that have received the threats need to send between 5 and 10 bitcoins to get rid of the attack.

According to the internet security company, the increase in the price of Bitcoin may be one of the factors that are serving as an incentive for these criminal groups to practice these extortion crimes.

„Pay Bitcoin or your website will be taken down“.

A company that depends on a website to make sales can find itself in trouble if it suffers a DDoS attack. With the site offline, no legitimate customer will be able to access the page, and therefore, there will be no sales.

The attacked company loses anyway, since even protecting the site has high costs, as well as mitigating the attack can cost expensive.

Radware explained that Bitcoin’s high took these groups of criminals by surprise. According to the security company, the criminals demanded 10 Bitcoins in order not to attack their victims, but the price of digital currency rose so fast that they had to reduce the amounts of extortion.

The price of Bitcoin has tripled since August 2020.

According to Radware, companies that are threatened and do not pay the amount charged have their websites attacked for about nine hours with a load of 200 Gbps being sent to their servers, which ends up knocking down the websites of companies that are not protected, preventing customers from buying any product.

Radware recommends that companies do not pay any kind of ransom for criminals, this will only make them come back more and more often. In these cases companies are advised to seek services from companies that offer security solutions.

Co-founder sells another 28.6m XRP

Drama around Ripple’s XRP: Co-founder sells another 28.6m XRP – despite SEC charges

Ripple Labs co-founder Jed McCaleb has sold over 28.6 million XRP tokens this week – despite ongoing charges against the company. The sale totals about $8.58 million at the time of writing.

The U.S. Securities and Exchange Commission (SEC) has filed charges against the company as well as co-founder Christian Larsen and current CEO Bradley Garlinghouse.

In a statement from the SEC, the charges relate to Ripple raising Bitcoin Cycle funds totalling more than $1.3 billion through an unregistered, ongoing offering of digital securities.

Jed is back

After a 25-day hiatus, McCaleb is back to selling XRP – according to crypto data researcher Leonidas Hadjiloizou. According to the researcher, this was now the second time McCaleb has taken a break from selling his XRP holdings.

The first time McCaleb had taken a break from selling Ripple’s XRP (To Buy Ripple Guide) was when he allowed a charity to sell its donations. He did not sell during that time.

Hadjiloizou explained that the reason for the 25-day pause in McCaleb’s sale of Ripples XRP was likely due to the SEC’s allegations and advice from legal counsel.

Ripple’s XRP has seen a dramatic drop in price in recent weeks following the SEC charges. After a strong rally in late 2020, Ripples XRP has since fallen fifty percent in price. It is now trading at $0.30 (down from $0.60 in mid-December).

Will the SEC complaint lead to dumping?

Several major exchanges have already announced that they will stop XRP trading on their platforms. This is likely an attempt to avoid a backlash from the SEC.

While 2021 was not a good start for Ripple, Polkadot has now overtaken Ripple in terms of market capitalisation. Polkadot now holds fourth place as the project’s price rises to new all-time highs.

Ripple may be in the spotlight for all the wrong reasons. However, CEO Bradley Garlinghouse took to Twitter to celebrate the appointment of new SEC chief Gary Gensler. Gensler has been described as pro-Bitcoin as well as a proponent of blockchain adoption.

Ripple CEO still has hope

Commenting on the appointment, Garlinghouse said:

„We are ready to work with SEC leadership and the broader Biden administration to find a path forward for blockchain and crypto innovation in the US.“

McCaleb has been steadily selling XRP in the past. The former CTO dumped over $400 million worth of XRP in 2020 alone.

McCaleb received about 4.7 billion XRP tokens during his time at and after leaving Ripple. It doesn’t look like he intends to stop selling while he still owns Ripple’s XRP (To buy Ripple with Paypal guide).

Bitcoin-Privatsphären-Wallet Wasabi eine Attacke?

Wie die Bitcoin-Privatsphären-Wallet Wasabi einer Attacke auf Tor widerstand

Ein Bug, der bestimmte Tor-Seiten lahmgelegt hat, hat einem Privacy Wallet, das sich auf dessen Dienste verlässt, nicht viel Probleme bereitet. Hier ist wie.

  • Ein Angriff oder Fehler auf Tor hat einige Seiten zum Absturz gebracht.
  • Betroffen waren Seiten, die v3-Tor-Adressen verwendeten.
  • Doch die Krypto-Brieftasche Wasabi konnte sich durchsetzen.

Alle modernen Onion-Adressen des anonymen Browser-Netzwerks Tor sind gestern offline gegangen, nachdem ein Bug das System lahmgelegt hat. Die Anzeichen deuten auf einen DDoS-Angriff hin, und die Unterbrechung verursachte laut Crypto Comeback bei einigen Nutzern der Bitcoin-Privatsphären-Wallet Wasabi Verbindungsprobleme.

„Es scheint, dass jemand seine eigene Tor-Implementierung gemacht hat, die Verzeichnisinformationen auf eine sehr unhöfliche Art und Weise abruft“…ein benutzerdefiniertes DDoS-Tool?“, sagte Roger Dingledine, ein Tor-Reporter, gestern. Dann wurde durch die Überlastung des Systems ein Fehler entdeckt, der das Netzwerk offline hielt.

Die Schwarzmarktplätze White House Market und Asean Market, das Nachrichtenbrett 8chan und Julian Assanges WikiLeaks gehörten zu den Dutzenden beliebter Seiten, die durch den Bug offline genommen wurden.

Aufgrund eines Implementierungsfehlers waren die v3-Zwiebel-Dienste heute früh instabil.
Ein Bugfix ist auf dem Weg.

Alles andere in Tor funktioniert einwandfrei, auch wenn der Konsens ein paar Stunden alt ist, und die v3-Zwiebel-Dienste sollten das auch tun.👇

– The Tor Project (@torproject) January 10, 2021

Wasabi, das seinen Datenverkehr durch Tor leitet, sagte heute in einem Blogpost, dass einige seiner Nutzer dadurch Verbindungsprobleme hatten. Alles in allem konnte Wasabi den Angriff jedoch automatisch abwehren, obwohl es moderne v3-Adressen verwendet, die andere Seiten offline brachten.

„Die meisten unserer Benutzer haben keine Unterbrechungen bemerkt, da Wasabi sich automatisch erholen konnte. Es gab ein paar Benutzer, die zeitweise Probleme mit der Tor-Verbindung hatten. Aber in den meisten dieser Fälle löste ein Neustart des Tor-Clients das Problem“, schrieb das Unternehmen.

Wasabi Wallet tunnelt den Datenverkehr durch Tor, um Transaktionen zu verschlüsseln. Es verbindet Benutzer mit zufälligen Bitcoin p2p Knoten und benutzt Tor, um Transaktionen zu verschleiern, so dass es fast unmöglich ist, herauszufinden, wie Gelder über die Blockchains fließen.

Wasabi wurde durch den Bug nicht ausgebremst, weil es ein Fallback-System hat, das sich über Tor mit dem regulären Internet verbindet. „Dies ermöglicht es dem Benutzer, weiter zu arbeiten, auch in ungewöhnlichen/offline-Zwiebel-Backend-Bedingungen“, sagte es.

Mehr auf dem Weg

Denial-of-Service-Angriffe sind auf dem Vormarsch. Laut einem Bericht des Cybersecurity-Unternehmens Kaspersky vom August 2020 haben sich die DDoS-Angriffe im zweiten Quartal 2020 im Vergleich zum gleichen Zeitraum 2019 verdreifacht.

Kim Crawley, Cybersecurity-Experte und Autor von The Pentester Blueprint, sagte gegenüber Decrypt, dass Tor-Seiten verwundbar sind, weil sie „nicht in der Lage sind, Dienste wie Cloudflare zu nutzen, um DDOS-Angriffe abzuschwächen.“

Marathon og DMG oppretter første nordamerikanske Coop Mining Pool

KORT

  • Marathon Patent Group og DMG Blockchain Solutions grunnlegger det første gruvebassenget i Nord-Amerika.
  • De tar sikte på å øke fortjenesten, diversifisere hashing-geografi og forbedre gjennomsiktigheten.
  • Marathon bestilte nylig 70 000 Antminers.

Partnerne tar sikte på å samle ressursene sine for å ytterligere diversifisere Bitcoin-hashing og øke gjennomsiktigheten blant gruvearbeidere.

Marathon Patent Group, Inc. (NASDAQ: MARA) og DMG Blockchain Solutions (TSX-V: DMGI) kunngjorde 5. januar sin intensjon om å lage et nordamerikansk gruvebasseng.

Økt fortjeneste og mer

Marathon og DMG, gjennom deres amerikanske datterselskap Blockseer, signerte en ikke-bindende avtale om å opprette en ideell organisasjon.

NGO, kalt Digital Currency Miners of North America (DCMNA), vil fokusere på bransjespørsmål. Disse inkluderer samle ressurser, dele overskudd, lobbyvirksomhet og øke gjennomsiktighet på flere nivåer.

Kombinere Hashrate

DCMNA vil kombinere hashingskapasiteten som medlemmene har gjort tilgjengelig. Belønninger vil bli gitt i forhold til hashing de gjør tilgjengelig for bassenget.

Marathon har allerede tilbudt seg å forplikte hele hashratet, omtrent 10,36 eksahash per sekund, i bassenget. Dette utgjør over 7% av den totale BTC-nettverksrenten.

Blockseer vil bidra med pooling-plattformen. Selskapet kunngjorde 29. oktober 2020 at det drev bassengprogramvare i privat beta. Eksterne revisorer vil angivelig bekrefte resultatene av pooling på Blockseer-plattformen.

AFL / CFT, DCMNA Style

Pooling-plattformen introdusert av Blockseer hevder at den også vil øke gjennomsiktigheten. Pooling-teknologien vil fjerne transaksjoner som Walletscore vurderer som risikofylte.

Som et resultat, er det mindre sannsynlig at blokkene som utvinnes ved bassenget, kommer til å bryte med den amerikanske myndighetens Office of Foreign Assets Control (OFAC). OFAC vil trolig være rettet mot transaksjoner knyttet til hvitvasking av penger og internasjonal finansiering av terrorisme.

Innsatsen bør også gjøre det lettere for DCMNA å lobbyere lovgivere og regulatorer. Marathon-styreleder Merrick Okamoto hevder at den forbedrede styringen bak DCMNAs samkjøring vil gjøre en forskjell.

Han hevder at til nå dominerte gruvebassenger i Asia, og åpenhet led.

„Vi har blitt frustrert over mangelen på åpenhet og reviderte data.“

Gruvedrift i Amerika

DCMNA kan finne nye medlemmer som venter på det. Dette er fordi gruvedrift blomstrer generelt i Nord-Amerika. For eksempel rapporterte BeInCrypto at selskaper prøver å diversifisere seg fra gruvedrift i Kina på grunn av mangel på åpenhet.

Dessuten gjør billige strømpriser i noen deler av Amerika, deprimerte lokale økonomier og høye bitcoin-priser gruvedrift i USA ser mer attraktivt ut.

Økningen i bitcoin-aktivitet allerede før prisene begynte å treffe nye høyder, økte også ordrer for nye miner. Marathon i seg selv øker gruvekapasiteten.

I slutten av desember bestilte Marathon totalt 70 000 Bitmain S-19 Antminer ASIC-er. Dette er den største enkeltordren i Bitmains historie til dags dato. Bestillingen er verdt over 170 millioner dollar.
