ASSA ABLOY Helps Organizations To Adopt Mobile Access Control

Protect yourself from online attacks that threaten your identity, your files, your system, and your financial well-being.


The smartphone is changing access control and security management at every scale and level, from global corporations to small companies. Making the switch to mobile access control, however, can seem daunting. Questions may arise around cost, practicality and the potential need for new door hardware. Yet going mobile is actually a lot simpler and quicker than many think, as one new guide explains.

Data from the recent Wireless Access Control Report 2021 suggests almost two-thirds of organizations have already adopted mobile access control, or plan to do so within two years. Industry analysts Omdia estimate that downloads of mobile credentials grew by 220% between 2018 and 2019 alone.

Mobile access control

The main benefits of mobile access control, the report suggests, are convenience, cost and security. All three of these advantages apply for any scale of organization. The user convenience of replacing plastic key-cards with secure ‘mobile keys’ on a smartphone is obvious. Identical benefits have already brought a mobile-first ethos to banking, travel booking, food delivery and many more sectors.

The ability to get the job done efficiently from anywhere is becoming essential

From a business perspective, too, the option for facilities managers to use their own smart device to issue, amend or revoke an employee’s mobile key brings added flexibility. It frees security staff from the desk and its dedicated admin PC. As the work patterns become fluid — IBM estimates 1.87 billion people will be mobile workers by 2022 — the ability to get the job done efficiently from anywhere is becoming essential. Access management via smartphone offers this.

Reissuing mobile credential

Secondly, mobile credentials are simpler and quicker to administer than key-cards, which brings significant cost savings. Deploying mobile keys on employee smartphones removes any need to purchase plastic cards or pay for their printing. Any missing plastic credential needs replacing; canceling and reissuing a mobile credential is essentially costless. Mobile access control also enables a business to reduce its use of non-recyclable plastics.

Sophisticated Spearphishing Campaign Targets Government Organizations, IGOs, and NGOs


Summary

This Joint Cybersecurity Advisory uses the MITRE Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK®) framework, Version 9. See the ATT&CK for Enterprise for all referenced threat actor tactics and techniques.

The Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) are engaged in addressing a spearphishing campaign targeting government organizations, intergovernmental organizations (IGOs), and non-governmental organizations (NGOs). A sophisticated cyber threat actor leveraged a compromised end-user account from Constant Contact, a legitimate email marketing software company, to spoof a U.S.-based government organization and distribute links to malicious URLs.[1] Note: CISA and FBI acknowledge open-source reporting attributing the activity discussed in the report to APT29 (also known as Nobelium, The Dukes, and Cozy Bear).[2,3] However, CISA and FBI are investigating this activity and have not attributed it to any threat actor at this time. CISA and FBI will update this Joint Cybersecurity Advisory as new information becomes available.

This Joint Cybersecurity Advisory contains information on tactics, techniques, and procedures (TTPs) and malware associated with this campaign. For more information on the malware, refer to Malware Analysis Report MAR-10339794-1.v1: Cobalt Strike Beacon.

CISA and FBI urge governmental and international affairs organizations and individuals associated with such organizations to adopt a heightened state of awareness and implement the recommendations in the Mitigations section of this advisory.

For a downloadable list of indicators of compromise (IOCs), refer to AA21-148A.stix, and MAR-10339794-1.v1.stix.

Technical Details

Based on incident reports, malware collection, and trusted third-party reporting, CISA and FBI are engaged in addressing a sophisticated spearphishing campaign. A cyber threat actor leveraged a compromised end-user account from Constant Contact, a legitimate email marketing software company, to send phishing emails to more than 7,000 accounts across approximately 350 government organizations, IGOs, and NGOs. The threat actor sent spoofed emails that appeared to originate from a U.S. Government organization. The emails contained a legitimate Constant Contact link that redirected to a malicious URL [T1566.002, T1204.001], from which a malicious ISO file was dropped onto the victim’s machine.

The ISO file contained (1) a malicious Dynamic Link Library (DLL) named Documents.dll [T1055.001], which is a custom Cobalt Strike Beacon version 4 implant, (2) a malicious shortcut file that executes the Cobalt Strike Beacon loader [T1105], and (3) a benign decoy PDF titled “Foreign Threats to the 2020 US Federal Elections” with file name “ICA-declass.pdf” (see figure 1). Note: The decoy file appears to be a copy of the declassified Intelligence Community Assessment pursuant to Executive Order 13848 Section 1(a), which is available at https://www.intelligence.gov/index.php/ic-on-the-record-database/results/1046-foreign-threats-to-the-2020-us-federal-elections-intelligence-community-assessment.

Figure 1: Decoy PDF: ICA-declass.pdf

Cobalt Strike is a commercial penetration testing tool used to conduct red team operations.[4] It contains a number of tools that complement the cyber threat actor’s exploitation efforts, such as a keystroke logger, file injection capability, and network services scanners. The Cobalt Strike Beacon is the malicious implant that calls back to attacker-controlled infrastructure and checks for additional commands to execute on the compromised system [TA0011].

The configuration file for this Cobalt Strike Beacon implant contained communications protocols, an implant watermark, and the following hardcoded command and control (C2) domains:

  • dataplane.theyardservice[.]com/jquery-3.3.1.min.woff2
  • cdn.theyardservice[.]com/jquery-3.3.1.min.woff2
  • static.theyardservice[.]com/jquery-3.3.1.min.woff2
  • worldhomeoutlet[.]com/jquery-3.3.1.min.woff2

The configuration file was encoded via an XOR with the key 0x2e and a 16-bit byte swap.

For more information on the ISO file and Cobalt Strike Beacon implant, including IOCs, refer to Malware Analysis Report MAR-10339794-1.v1: Cobalt Strike Beacon.

Mitigations

CISA and FBI urge CI owners and operators to apply the following mitigations.

  • Implement multi-factor authentication (MFA) for every account. While privileged accounts and remote access systems are critical, it is also important to ensure full coverage across SaaS solutions. Enabling MFA for corporate communications platforms (as with all other accounts) provides vital defense against these types of attacks and, in many cases, can prevent them.
  • Keep all software up to date. The most effective cybersecurity programs quickly update all of their software as soon as patches are available. If your organization is unable to update all software shortly after a patch is released, prioritize implementing patches for CVEs that are already known to be exploited.
  • Implement endpoint and detection response (EDR) tools. EDR allows a high degree of visibility into the security status of endpoints and is can be an effective tool against threat actors.
    Note: Organizations using Microsoft Defender for Endpoint or Microsoft 365 Defense should refer to Microsoft: Use attack surface reduction rules to prevent malware infection for more information on hardening the enterprise attack surface.
  • Implement centralized log management for host monitoring. A centralized logging application allows technicians to look out for anomalous activity in the network environment, such as new applications running on hosts, out-of-place communication between devices, or unaccountable login failures on machines. It also aids in troubleshooting applications or equipment in the event of a fault. CISA and the FBI recommend that organizations:
    • Forward logs from local hosts to a centralized log management server—often referred to as a security information and event management (SIEM) tool.
    • Ensure logs are searchable. The ability to search, analyze, and visualize communications will help analysts diagnose issues and may lead to detection of anomalous activity.
    • Correlate logs from both network and host security devices. By reviewing logs from multiple sources, an organization can better triage an individual event and determine its impact to the organization as a whole.
    • Review both centralized and local log management policies to maximize efficiency and retain historical data. Organizations should retain critical logs for a minimum of 30 days.
  • Deploy signatures to detect and/or block inbound connection from Cobalt Strike servers and other post-exploitation tools.
  • Implement unauthorized execution prevention by disabling macro scripts from Microsoft Office files transmitted via email. Consider using Office Viewer software to open Microsoft Office files transmitted via email instead of full Microsoft Office suite applications.
  • Configure and maintain user and administrative accounts using a strong account management policy.
    • Use administrative accounts on dedicated administration workstations.
    • Limit access to and use of administrative accounts.
    • Use strong passwords. For more information on strong passwords, refer to CISA Tip: Choosing and Protecting Passwords and National Institute of Standards (NIST) SP 800-63: Digital Identity Guidelines: Authentication and Lifecycle Management.
    • Remove default accounts if unneeded. Change the password of default accounts that are needed.
    • Disable all unused accounts.
  • Implement a user training program and simulated attacks for spearphishing to discourage users from visiting malicious websites or opening malicious attachments and re-enforce the appropriate user responses to spearphishing emails.

People – and their identities – are now the single control point across users, devices, and networks. This makes Identity the foundation of a Zero Trust strategy, ensuring only the right people have access to the right resources at the right time. The ‘Zero Trust’ security emphasizes that enterprises should have a “trusted” internal network and an “untrusted” external network.

The increasing adoption of mobile and cloud coupled with the recent pandemic showcases that we can no longer have a network perimeter-centric view of security. Instead, we need to securely enable access for the various stakeholders; including employees, partners, contractors, etc., regardless of their location, device, or network.

There is no silver bullet in achieving a ‘Zero Trust’ security architecture. Still, identity and access management is the core technology that sets the stage for the ‘zero trust’ journey. The ‘people’ become the new perimeter in this journey, with identity-forming the critical component to establishing a secure environment.

Join us live for a 45-minute session to hear from Deputy, an Okta customer who will share their journey on how to extend the power of the cloud to simplify and secure the way your employees, customers, and partners connect to technology.

Key discussion points:

  • The impact a fragmented workforce is having on security principles
  • Zero trust strategy: Understanding that people are now the single control point

Global Email Security Market Forecast Report 2021-2025: New Malware Techniques Drive Market Growth as Organizations Accelerate Cloud Migration Due to the COVID-19 Pandemic – ResearchAndMarkets.com | Business


DUBLIN–(BUSINESS WIRE)–Apr 23, 2021–

This research service analyzes the global email security market.

Email remains the number one threat vector. It is the primary mode of corporate communication and the de facto standard for B2B and B2C communications. During the COVID-19 pandemic, email continues to be the chief channel for business communication, and this trend is driven by the surging trend of working from home.

Over the past few years, the complexity and the volume of threats have increased significantly. Email-based threats have become big business; specific verticals and individuals within organizations are targeted. Threat vectors continue to evolve, and the need for secure email has never been stronger. Attackers are more focused on people and less on systems. Business email compromise (BEC) fraud continues to affect organizations, both large and small. Consequently, traditional security solutions that are designed to protect systems and infrastructure are now inadequate.

Sophisticated and highly targeted email-borne attacks are on the rise, and many of these attacks use social engineering techniques. For businesses of all sizes, this is a serious problem as the legitimate communication channel they rely on extensively, email, is also the channel of choice to deliver malware and malwareless attacks. Advanced attacks combine email and cloud accounts. Cybercriminals are also leveraging pandemic-driven fears and uncertainties to launch their attacks.

The most significant trend in the market is the acceleration of the migration to the cloud. Customers are adopting cloud-based mailbox services and moving their email security to the cloud from on-premise appliances. The substantial adoption of Microsoft Office 365 has caused the biggest loss of email security posture for organizations.

As a result, organizations are looking for integrated solutions to increase operational efficiencies while gaining stronger and more comprehensive security. In such a competitive environment, email security vendors must be able to differentiate themselves.
