McAfee Labs Threat Advisory Adware-SearchSuite June 22, 2018 McAfee Labs periodically publishes Threat Advisories to provide customers with a detailed analysis of prevalent malware. This Threat Advisory contains behavioral information, characteristics and symptoms that may be used to mitigate or discover this threat, and suggestions for mitigation in addition to the coverage provided by the DATs. To receive a notification when a Threat Advisory is published by McAfee Labs, select to receive “Malware and Threat Reports” at the following URL: https://www.mcafee.com/enterprise/en-us/sns/preferences/sns-form.html Summary Detailed information about the threat, its propagation, characteristics and mitigation are in the following sections: Infection and Propagation Vectors Mitigation Characteristics and Symptoms Restart Mechanism McAfee Foundstone Services The Threat Intelligence Library contains the date that the above signatures were most recently updated. Please review the above mentioned Threat Library for the most up to date coverage information. Infection and Propagation Vectors Adware-SearchSuite is a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them. Mitigation Mitigating the threat at multiple levels like file, registry and URL could be achieved at various layers of McAfee products. Browse the product guidelines available here (click Knowledge Center, and select Product Documentation from the Support Content list) to mitigate the threats based on the behavior described in the Characteristics and symptoms section. -

Securing Your Email in 13 Steps: the Email Security Checklist Handbook Securing Your Email in 13 Steps
HANDBOOK Securing Your Email in 13 Steps: The Email Security Checklist handbook Securing Your Email in 13 Steps overview You’ve hardened your servers, locked down your website and are ready to take on the internet. But all your hard work was in vain, because someone fell for a phishing email and wired money to a scammer, while another user inadvertently downloaded and installed malware from an email link that opened a backdoor into the network. Email is as important as the website when it comes to security. As a channel for social engineering, malware delivery and resource exploitation, a combination of best practices and user education should be enacted to reduce the risk of an email-related compromise. By following this 13 step checklist, you can make your email configuration resilient to the most common attacks and make sure it stays that way. 2 @UpGuard | UpGuard.com handbook Securing Your Email in 13 Steps 1. Enable SPF How do you know if an email is really from who it says it’s from? There are a couple of ways to answer this question, and Sender Policy Framework (SPF) is one. SPF works by publishing a DNS record of which servers are allowed to send email from a specific domain. 1. An SPF enabled email server receives an email from [email protected] 2. The email server looks up example.com and reads the SPF TXT record in DNS. 3. If the originating server of the email matches one of the allowed servers in the SPF record, the message is accepted. -
Cyber Risks to Public Safety: Ransomware, September 2020
CYBER RISK TO PUBLIC SAFETY: RANSOMWARE RANSOMWARE IMPACTS ON PUBLIC SAFETY If you are experiencing a ransomware attack, please go directly to page 3 for incident reporting resources Ransomware is a type of malicious software that encrypts information stored on hard drives or network drives and disrupts access to compromised devices or networks. Ransomware applications threaten to erase, lock, or otherwise damage compromised drives and data unless payment is provided. Ransomware programs often elicit a sense of urgency (e.g., a short deadline for payment) to encourage affected organizations to pay. Ransomware applications may threaten to escalate demands (e.g., increase payment) if payment is not provided quickly. Even when payments are provided, malicious actors may steal sensitive information, default on agreements to restore access, or conduct follow-up cyberattacks. While ransomware typically aims to extort money from organizations, malicious actors may also target public safety agencies or critical infrastructure with the goal of disrupting emergency response capabilities.1, 2 Figure 1. Recent Ransomware Attack Statistics Ransomware can have a significant impact on public safety operations, including services provided by fire, emergency medical services, law enforcement, emergency communication centers/public safety answering points, and other public safety partners. Disruptions to public safety operations directly and negatively impact the health and safety of the communities they serve. For example, delays dispatching fire and emergency medical services may lead to increased loss of life and property damage. Malicious actors may target public safety agencies specifically to exploit these negative outcomes, creating a strong sense of urgency to accommodate perpetrator demands. Public safety agencies are highly encouraged to plan and prepare for a ransomware event to mitigate service disruptions, conduct effective response operations, and ensure rapid recovery. -
