RDP Security Explained

securingtomorrow.mcafee.com/other-blogs/mcafee-labs/rdp-security-explained/ Recently, McAfee released a blog related to the wormable RDP vulnerability referred to as CVE-2019-0708 or Bluekeep. The blog highlights a particular vulnerability in RDP which was deemed critical by Microsoft due to the fact that it exploitable over a network connection without authentication. These attributes make it particularly wormable it can easily be coded to spread itself by reaching out to other accessible networked hosts, simila. When trying to run an efficient IT organization, having remote access to certain computer systems might be essential. Unfortunately, when not implemented correctly, the tools that make remote access possible also open your systems up to unwanted guests. In the last few years there have been far too many examples of where vulnerable RDP access gave way to a full-scale network compromise.

BlueStacks Flaw Lets Attackers Remotely Control Android Emulator

www.bleepingcomputer.com/news/security/bluestacks-flaw-lets-attackers-remotely-control-android-emulator/ Vulnerabilities in the BlueStacks Android emulator were fixed at the end of May that allowed attackers to perform remote code execution, information disclosure, and to steal backups of the VM and its data. In BlueStacks versions earlier than v4.90.0.1046, a DNS rebinding vulnerability existed that allowed attackers to gain access to the emulator’s IPC functions. These functions could then be used for a variety of different attacks ranging from remote code execution to information disclosure. This vulnerability was discovered and reported by security researcher Nick Cano in April and was fixed in BlueStacks, which was released on May 27th, 2019 along with an advisory.

Malspam Campaigns Hide Infostealers in ISO Image Files

www.bleepingcomputer.com/news/security/malspam-campaigns-hide-infostealers-in-iso-image-files/ Multiple malicious campaigns observed in April concealed LokiBot and Nanocore malware inside ISO image files small enough to fit into an email attachment. Both LokiBot and Nanocore incorporate data-stealing capabilities. They target web browsers, email clients, remote admin tools (SSH, VNC, and RDP), and clipboard data. They can also collect information about documents present on the system and monitor user keystrokes to extract more sensitive details. Security researchers discovered 10 variants of this type of campaign, with variations in the ISO images and messages delivered to potential victims. The endeavors appear to follow the “spray and pray” principle as they did not target specific individuals or businesses.. See also:


Microsoft OneDrive Has 60% Jump in Hosting of Malicious Files

www.bleepingcomputer.com/news/security/microsoft-onedrive-has-60-percent-jump-in-hosting-of-malicious-files/ A retrospective look at the phishing trends from the first quarter of 2019 shows a steep jump in the use of Microsoft’s OneDrive file sharing service to host malicious files. While cybercriminals have abused the service in the past to host their phishing attacks, researchers from FireEye noticed a dramatic increase lately, compared to the last quarter of 2018. OneDrive’s popularity rose from almost complete disregard to a share above 60%. This preference is topped only by Dropbox, which has also seen an increased number of detections, albeit the comparative gap between the last two quarters is much smaller, around 10%. A similar picture is available for Google Drive, where the quarter on quarter difference is less than 20%. For both Dropbox and Google Drive, the difference could be accounted for by a surge in activity at the beginning of this year.

The report, based on the analysis of 1.3 billion emails, further suggests that phishing attacks have risen by 17 percent over Q1 2019. In total, almost 30 percent of all detections impersonate well-known brands including Microsoft, OneDrive, Apple, Amazon, and PayPal.
