Cybersecurity News of the Week, February 10, 2019
Microsoft recently revealed that vulnerabilities, referred to collectively as "ProxyLogon," in on-premises Microsoft Exchange servers were being exploited by threat actors, including HAFNIUM , since at least January The most severe of these vulnerabilities could allow a threat actor to execute code in the context of the server, and possibly view, modify, or delete data. Once exploitation occurs, the adversary could gain persistence to, and control over, the entire network. In addition to the nation-state hackers that first exploited several zero-day vulnerabilities in Microsoft Exchange, ransomware threat actors—such as DearCry , BlackKingdom , and Epsilon Red —and cryptocurrency miners—such as Lemon Duck and Monero —are also targeting vulnerable servers.
Exploitation of these vulnerabilities is now indiscriminate and widespread. Organizations using on-premises versions of Exchange are highly advised to prioritize patching and search their systems for signs of compromise. Patching an already compromised network will not mitigate an intrusion that occurred prior to patch deployment.

How blockchain-based apps and sites resist DDoS attacks
However, the lack of sufficient security in these newly connected devices creates meaningful risk to consumers and to the basic functionality of the Internet. As seen this past fall, the Mirai botnet used compromised IP cameras and video recorders to launch the DDoS attack that crippled Dyn, a DNS provider, and impaired Internet access to many popular websites for millions of users. While Mirai perpetrated one of the most impactful recent DDoS attacks, this will surely not be the last event. Such attacks were once the purview of sophisticated hackers. Ever-increasing broadband capacity, a boon to consumers and the economy, also enables increased volumetric attacks.
BLOG: Beyond the scam: geopolitical implications of the Twitter hack
Security researchers have dubbed this event Hafnium, named after the Chinese-based espionage group first seen attacking servers. Once compromised, multiple backdoors  are installed on systems that will likely lead to complete takeover of hacked systems. As of March 5 th , over 30, U. If you are running a Microsoft Exchange server  , hopefully you have addressed this issue; if not, you need to act now and install emergency patches  provided by Microsoft. Security researchers at UNITB have put together several resources that include links to patches, methods to test your server, and resources to restore a compromised server. Investigative reporter, Brian Krebs, has a detailed article on the issue at KrebsonSecurity. Major security events such as this are a reminder to evaluate your own security practices and prepare for the next big event. This incident demonstrates how fast cybercriminal groups will pounce on the opportunity to exploit vulnerable systems, so it is a good time to highlight security practices that can help defend against future threats. The Hafnium incident demonstrates the classic cat-and-mouse game between cybercriminals and software vendors.
Is the KYC Data Hack for Leading Cryptocurrency Exchanges Fake News?
Microsoft on Friday warned of active attacks exploiting unpatched Exchange Servers carried out by multiple threat actors, as the hacking campaign is believed to have infected tens of thousands of businesses, government entities in the U. The company said "it continues to see increased use of these vulnerabilities in attacks targeting unpatched systems by multiple malicious actors beyond HAFNIUM," signaling an escalation that the breaches are no longer "limited and targeted" as was previously deemed. According to independent cybersecurity journalist Brian Krebs , at least 30, entities across the U. Victims are also being reported from outside the U.

Microsoft Vulnerability Highlights Steps We All Need to Take
Financial data aggregation is the backend technology that powers many of the financial services apps we love to use and build today. Historically there have been two leaders of financial data aggregation: Plaid and Yodlee. Recent Open Banking laws are giving users more control of their data. Emerging asset classes like cryptocurrency are breaking into mainstream and becoming extremely important. APIs, once a rarity, are now becoming commonplace. What does this mean for teams and developers wanting to incorporate financial data into their apps?

The leaked FBI document details three cases in which the Panamanian 'instant' crypto exchange MorphToken was "likely" used by bad actors to launder illicit-origin Bitcoin by converting it into Monero; two of the darknet markets DNMs named include Apollon and Cryptonia. The FBI also analyzed commission fees from Bitcoin transactions conducted on Cryptonia between May and September , revealing that the assets were sent to addresses associated with MorphToken. Law enforcement assumes that darknet market actors are not chain-hopping into Monero with the intent of portfolio diversification. Per Bureau policy, the FBI declined to comment on this story.

VentureBeat Homepage. Join today's leading executives online at the Data Summit on March 9th. Register here. Sometimes, truth is stranger than fiction! We live in an age where DDoS attacks will only grow over time, while becoming more mature in the process. Considering a rising number of unsecured IoT devices are connected to one another, the potential for DDoS attacks to creep in and overpower an organization is very real.
Proofpoint researchers have identified an intriguing Advance Fee Fraud scheme sending low volume email campaigns and employing advanced social engineering tactics to swindle unsuspecting victims out of Bitcoin. This scheme spreads credentials to alleged private Bitcoin investment platforms and lures victims with the promise of withdrawing hundreds of thousands of dollars worth of cryptocurrency from an already established account on the platform s. While being very similar to traditional Advance Fee Fraud schemes, this set of campaigns is much more sophisticated from a technical standpoint, is fully automated, and requires substantial victim interaction.
