Syxsense Changes Game with Introduction of New Mobile Device Management Solution

Syxsense's MDM solution broadens the reach of IT managers to mobile devices running iOS, iPadOS, and Android.

Mobile Device Management Added to Syxsense

ALISO VIEJO, Calif., March 29, 2022 /PRNewswire/ –– Syxsense, a global leader in IT and security management solutions, announced today the availability of their solution for Mobile Device Management (MDM).

Available immediately, the MDM solution from Syxsense is the first solution on the market that broadens the reach of IT managers to now include mobile devices running iOS, iPadOS, and Android, in addition to previously supported Windows, Linux and Mac environments.

The ongoing trend of remote and hybrid work models has increased the criticality of bringing mobile devices under the umbrella of IT managed security, both company issued as well as BYOD (bring your own device.) MDM is now recognized by analyst firm Gartner as a key requirement of an effective Unified Endpoint Management (UEM) strategy, which has seen a surge in investment recently. Gartner writes “UEM investment has grown in response to the greater acceptance of remote working and the requirement to manage, patch and support Windows 10 and macOS PCs as well as mobile devices, regardless of location.”

Syxsense’ MDM offering includes all the tools necessary to apply effective management to mobile endpoints, including Device Enrollment, Inventory and Configuration Management, Application Deployment and Rollback, Data Containerization, and Remote Device Lock/Reset/Wipe, making it possible for IT to wipe sensitive data from lost or stolen devices.

“The Syxsense approach of unifying management of all IT devices into a single console that spans device management, device security and vulnerability remediation, has resonated with our customers, and is the catalyst for our recent explosive growth,” explains Ashley Leonard, founder and CEO of Syxsense. “This industry-first ability to now manage mobile devices within the same platform and methodology as other IT assets has been hugely popular with our early adopters.”

Syxsense Mobile Device Management is available as an add-on module to Syxsense Secure, which already includes management and security tools for servers, desktops, laptops, and virtual machines. It will also be included in an upcoming release of a bundled offering targeted at enterprise customers who wish to manage the broad scope of their IT devices from within a single console.

Other Included Features

Syxsense has also released updates to their existing offerings to now provide integration with Active Directory (AD) allowing IT managers to manage on-premise AD devices from the cloud. Syxsense discovers devices as they are added to OUs (organizational units) and automatically applies the appropriate policies.

This union of Syxsense Cortex™ and AD enables cradle to grave lifecycle management based on OU membership, rather than having to manually apply tasks to new devices and is a huge time saver to the IT team.

Newly updated Syxsense Manage is now also the first patch management product on the market that offers active Patch Tuesday scheduling for phased deployments. The recurring windows are set relative to the moving target of the second Tuesday, making it easy to deploy new content automatically. Missing a deployment of Microsoft’s recommended patches is a major factor in unprotected or under-protected environments and leaves the door open for attack.

Syxsense products support iOS, iPadOS, Android, Windows Servers, Windows Desktop, MacOS devices, and a variety of Linux distributions, now also including the enterprise-friendly Rocky Linux.

Information and pricing on these new Syxsense products is available on the Syxsense website. Qualified customers are also able to schedule a personalized demo of the existing products and the new MDM module, and receive a $100 gift card in return, by registering here.

WhisperGate and HermeticWiper: Critical Public Aware Vulnerabilities

By BlogNo Comments

WhisperGate and HermeticWiper: Critical Public Aware Vulnerabilities

WhisperGate, a new malware, is being used to target organizations in Ukraine and companies with connections to the country.

WhisperGate Malware Is Targeting Ukraine

The Microsoft Threat Intelligence Center (MSTIC) has disclosed that malware known as WhisperGate is being used to target organizations in Ukraine and companies with connections to the country. According to Microsoft, WhisperGate is intended to be destructive and designed to render targeted devices inoperable.

Additionally, several cybersecurity researchers disclosed that malware known as HermeticWiper was being used against organizations in Ukraine. According to SentinelLabs, the malware targets Windows devices only by manipulating the master boot record resulting in subsequent boot failure.

These attacks are not intended to be used to extract a ransom, but to cause the maximum IT outage possible in an organization, by turning all devices into expensive door stops.

The National Cyber Security Centre in the UK are not aware of any current specific threats to UK organizations in relation to events in and around Ukraine, but there has been a historical pattern of cyberattacks on Ukraine with international consequences.

Threat actors have deployed destructive malware, including both WhisperGate and HermeticWiper against organizations in Ukraine to destroy computer systems and render them inoperable.

A joint Cybersecurity Advisory (CSA) between the Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) provided information on WhisperGate and HermeticWiper malware as well as open-source indicators of compromise (IOCs) for organizations to detect and prevent the malware.

This data has been provided to help secure the maximum number of organizations around the world.

Identifying WhisperGate

The following payloads are used to both infect and launch the WhisperGate attack. These are files which have known file hashes.

Even if the file name has changed, Syxsense can still detect this threat and keep your endpoints secure. The infection comes in 2 parts, first a stage file is copied to the PC which then launched stage 2 which causes the end result.

Name File Category File Hash
WhisperGate stage1.exe a196c6b8ffcb97ffb276d04f354696e2391311db3841ae16c8c9f56f36a38e92
WhisperGate stage2.exe dcbbae5a1c61dbbbb7dcd6dc5dd1eb1169f5329958d38b58c3fd9384081c9b78

Identifying HermeticWiper

Any of the following payloads could be used to both infect and launch the HermeticWiper attack. These are files which have known file hashes, even if the file name has changed Syxsense can still detect this threat.

Similar to WhisperGate, these are files delivered initially as a Trojan, and from there it downloads and launches the sophisticated attack.

Linux Vulnerabilities of the Week: March 7, 2022

By NewsNo Comments

Linux Vulnerabilities of the Week: March 7, 2022

See this week's top Linux issues and keep your IT environment protected from the latest March 2022 Linux vulnerabilities.

1. Failure to properly escape SQL input in Cyrus SASL affecting Red Hat Enterprise Linux 6

Severity: Critical         CVSS Score: 9.1

This is a flaw in the SQL plugin shipped with Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28. A remote attacker can execute arbitrary SQL commands due to the failure to properly escape the SQL input. This issue can lead to the escalation of privileges.

The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Syxscore Risk Alert

This vulnerability has a critical risk although it requires high privileges to be exploited, this can be exposed over any network, with low complexity, and without user interaction. Besides, this flaw allows a lateral attack to be carried out.

  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: High
  • User Interaction: None
  • Scope (Jump Point): Changed

CVE Reference(s): CVE-2022-24407

2. Out-of-bounds heap read/write vulnerability in Samba

Severity: Important    CVSS Score: 8.8

Samba versions before 4.13.17, 4.14.12, and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. Due to a boundary error when processing EA metadata while opening files in smbd within the VFS Samba module, a remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.

The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Syxscore Risk Alert

This vulnerability has a major risk as this can be exposed over any network, with low complexity, low privileges, and without user interaction.

  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: Low
  • User Interaction: None
  • Scope (Jump Point): Unchanged

CVE Reference(s): CVE-2021-44142

3. Double-free of the virtual attribute context in persistent search in ds-base affecting Red Hat Enterprise Linux 8

Severity: Important    CVSS Score: 7.5

This is double-free in the way 389-ds-base handles virtual attributes context in persistent searches, which an attacker could use to send a series of search requests, forcing the server to behave unexpectedly, and crash.

The highest threat from this vulnerability is to system availability.

Syxscore Risk Alert

This vulnerability has a major risk as this can be exposed over any network, with low complexity, no privileges, and without user interaction.

  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: None
  • User Interaction: None
  • Scope (Jump Point): Unchanged

CVE Reference(s): CVE-2021-4091

4. Special character breaks path in XML parsing in PHP

Severity: Medium       CVSS Score: 5.3

This is a flaw in PHP. The main cause of this vulnerability is improper input validation while parsing an Extensible Markup Language(XML) entity. A special character could allow an attacker to traverse directories.

The highest threat from this vulnerability is to confidentiality and integrity.

Syxscore Risk Alert

This vulnerability has a moderate risk as this can be exposed over any network, with low complexity, no privileges, and without user interaction.

  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: None
  • User Interaction: None
  • Scope (Jump Point): Unchanged

CVE Reference(s): CVE-2021-21707

5. RPM’s signature vulnerability

Severity: Low  CVSS Score: 4.4

There is a flaw in RPM’s signature functionality. OpenPGP subkeys are associated with a primary key via a “binding signature. RPM does not check the binding signature of subkeys before importing them. If an attacker can add or socially engineer another party to add a malicious subkey to a legitimate public key, RPM could wrongly trust a malicious signature.

The highest threat from this vulnerability is to data integrity.

Syxscore Risk Alert

This vulnerability has a low risk as although this requires access to the same network as the device, complex attack and user interaction to be exploited, it can be exposed with low privileges.

  • Attack Vector: Local
  • Attack Complexity: High
  • Privileges Required: Low
  • User Interaction: Required
  • Scope (Jump Point): Unchanged

CVE Reference(s): CVE-2021-3521
