bitcoin hacking | Breaking Cybersecurity News | The Hacker News

Though once synonymous with underground networks and black hat hackers, bitcoin and other cryptocurrencies have gone mainstream over the past two years. In 2017, we saw the skyrocket of bitcoin to an all-time high of close to $20,000 followed by a significant decline the following year. But beyond the ups and downs in the market for the world's largest cryptocurrency is a much more sinister story revolving around cyber-attacks of the economy's newest asset class. In 2018, it estimated that as much as $1.7 billion worth of cryptocurrencies were swindled away from investors (likely more) through a variety of means. Whether accomplished through hacking, phishing, or other forms of scamming, it's clear that the crypto industry is facing a serious dilemma with security. For a technological movement based on decentralization and the advantages it offers for security, the number of breaches occurring is startling. Cryptocurrencies offer users a way to send money with

Researchers have been warning for years about critical issues with the Signaling System 7 (SS7) that could allow hackers to listen in private phone calls and read text messages on a potentially vast scale, despite the most advanced encryption used by cellular networks. Despite fixes being available for years, the global cellular networks have consistently been ignoring this serious issue, saying that the exploitation of the SS7 weaknesses requires significant technical and financial investment, so is a very low risk for people. However, earlier this year we saw a real-world attacks, hackers utilised this designing flaw in SS7 to drain victims' bank accounts by intercepting two-factor authentication code (one-time passcode, or OTP) sent by banks to their customers and redirecting it to themselves. If that incident wasn't enough for the global telecoms networks to consider fixing the flaws, white hat hackers from Positive Technologies now demonstrated how cybercriminals

Shadow apps, a segment of Shadow IT, are SaaS applications purchased without the knowledge of the security team. While these applications may be legitimate, they operate within the blind spots of the corporate security team and expose the company to attackers.  Shadow apps may include instances of software that the company is already using. For example, a dev team may onboard their own instance of GitHub to keep their work separate from other developers. They might justify the purchase by noting that GitHub is an approved application, as it is already in use by other teams. However, since the new instance is used outside of the security team's view, it lacks governance. It may store sensitive corporate data and not have essential protections like MFA enabled, SSO enforced, or it could suffer from weak access controls. These misconfigurations can easily lead to risks like stolen source code and other issues. Types of Shadow Apps  Shadow apps can be categorized based on their interac
