U.S. and Bulgarian authorities this week took control of the dark web site used by the NetWalker ransomware cybercrime group to publish data stolen from its victims. "We are striking back against the growing threat of ransomware by not only bringing criminal charges against the responsible actors, but also disrupting criminal online infrastructure and, wherever possible, recovering ransom payments extorted from victims,"  said  Acting Assistant Attorney General Nicholas L. McQuaid of the Justice Department's Criminal Division. "Ransomware victims should know that coming forward to law enforcement as soon as possible after an attack can lead to significant results like those achieved in today's multi-faceted operation." In connection with the takedown, a Canadian national named Sebastien Vachon-Desjardins from the city of Gatineau was charged in the U.S. state of Florida for extorting $27.6 million in cryptocurrency from ransom payments. Separately, the...

Law enforcement agencies from as many as eight countries dismantled the infrastructure of Emotet , a notorious email-based Windows malware behind several botnet-driven spam campaigns and ransomware attacks over the past decade. The coordinated takedown of the botnet on Tuesday — dubbed " Operation Ladybird " — is the result of a joint effort between authorities in the Netherlands, Germany, the U.S., the U.K., France, Lithuania, Canada, and Ukraine to take control of servers used to run and maintain the malware network. "The Emotet infrastructure essentially acted as a primary door opener for computer systems on a global scale," Europol  said . "What made Emotet so dangerous is that the malware was offered for hire to other cybercriminals to install other types of malware, such as banking Trojans or ransomware, onto a victim's computer." More Than a Malware  Since its first identification in 2014,  Emotet  has evolved from its initial roots as a cr...

Cybersecurity researcher Paul Litvak today disclosed an unpatched vulnerability in Microsoft Azure Functions that could be used by an attacker to escalate privileges and escape the Docker container used for hosting them. The findings come as part of Intezer Lab 's investigations into the Azure compute infrastructure. Following disclosure to Microsoft, the Windows maker is said to have "determined that the vulnerability has no security impact on Function users, since the host itself is still protected by another defense boundary against the elevated position we reached in the container host." Azure Functions , analogous to Amazon AWS Lambda, is a serverless solution that allows users to run event-triggered code without having to provision or manage infrastructure explicitly while simultaneously making it possible to scale and allocate compute and resources based on demand. By incorporating Docker into the mix, it makes it possible for developers to easily deploy and ...

Newly discovered security vulnerabilities in ADT's Blue (formerly LifeShield) home security cameras could have been exploited to hijack both audio and video streams. The  vulnerabilities  (tracked as CVE-2020-8101) were identified in the video doorbell camera by Bitdefender researchers in February 2020 before they were eventually addressed on August 17, 2020. LifeShield was acquired by Florida-based ADT Inc. in 2019, with Lifeshield's DIY home security solutions rebranded as Blue as of January 2020. The company's products had a 33.6% market share in the U.S. last year. The security issues in the doorbell camera allow an attacker to Obtain the administrator password of the camera by simply knowing its MAC address, which is used to identify a device uniquely Inject commands locally to gain root access, and Access audio and video feeds using an unprotected  RTSP  (Real-Time Streaming Protocol) server The doorbell is designed to periodically send heartbeat mes...

A newly devised variant of the  NAT Slipstreaming attack  can be leveraged to compromise and expose any device in an internal network, according to the latest research. Detailed by enterprise IoT security firm Armis, the  new attack  (CVE-2020-16043 and CVE-2021-23961) builds on the previously disclosed technique to bypass routers and firewalls and reach any unmanaged device within the internal network from the Internet. First  disclosed  by security researcher Samy Kamkar in late October 2020, the JavaScript-based attack relied on luring a user into visiting a malicious website to circumvent browser-based port restrictions and allow the attacker to remotely access TCP/UDP services on the victim's device, even those that were protected by a firewall or NAT. Although partial mitigations were released on November 11 to thwart the attack in  Chrome 87 ,  Firefox 84 , and  Safari  by preventing connections on port 5060 or 5061, Armis re...

With so much of the world transitioning to working, shopping, studying, and streaming online during the coronavirus pandemic, cybercriminals now have access to a larger base of potential victims than ever before. "Zoombomb"  became the new photobomb—hackers would gain access to a private meeting or online class hosted on Zoom and shout  profanities and racial slurs  or flash  pornographic images . Nation-state hacker groups mounted attacks against organizations involved in the coronavirus pandemic response, including the World Health Organization and Centers for Disease Control and Prevention, some in an attempt to politicize the pandemic. Even garden-variety cyber attacks like email phishing, social engineering, and refund theft took on a darker flavor in response to the widespread economic precarity brought on by the pandemic.  "Hackers were mostly trying to take advantage of people's fear by offering medical equipment like thermometers and masks for cheap...

Creating workflows around verifying password resets can be challenging for organizations, especially since many have shifted work due to the COVID-19 global pandemic. With the numbers of cyberattacks against businesses exploding and compromised credentials often being the culprit, companies have to bolster security around resetting passwords on user accounts. How can organizations bolster the security of password resets for remote workers? One security workflow might involve having manager approval before IT helpdesk technicians can change a remote worker's password. In this way, the user's manager is involved in the process. Additionally, some organizations might opt to allow managers themselves the ability to change end-user passwords. How can this be configured in Active Directory? Also, is there a more seamless solution for requiring manager approval for password resets? Why password reset security is critical This past year has undoubtedly created many IT helpdesk st...
