Ivanti, the company behind Pulse Secure VPN appliances, has published a security advisory for a high severity vulnerability that may allow an authenticated remote attacker to execute arbitrary code with elevated privileges. "Buffer Overflow in Windows File Resource Profiles in 9.X allows a remote authenticated user with privileges to browse SMB shares to execute arbitrary code as the root user," the company  said  in an alert published on May 14. "As of version 9.1R3, this permission is not enabled by default." The flaw, identified as CVE-2021-22908, has a CVSS score of 8.5 out of a maximum of 10 and impacts Pulse Connect Secure versions 9.0Rx and 9.1Rx. In a report detailing the vulnerability, the CERT Coordination Center said the issue stems from the gateway's ability to connect to Windows file shares through a number of CGI endpoints that could be leveraged to carry out the attack. "When specifying a long server name for some SMB operations, the ...

Adversaries could exploit newly discovered security weaknesses in Bluetooth Core and Mesh Profile Specifications to masquerade as legitimate devices and carry out man-in-the-middle (MitM) attacks. "Devices supporting the Bluetooth  Core  and  Mesh Specifications  are vulnerable to impersonation attacks and AuthValue disclosure that could allow an attacker to impersonate a legitimate device during pairing," the Carnegie Mellon CERT Coordination Center  said  in an advisory published Monday. The two Bluetooth specifications define the standard that allows for many-to-many communication over the short-range wireless technology to facilitate data transfer between devices in an ad-hoc network. The Bluetooth Impersonation AttackS, aka BIAS , enable a malicious actor to establish a secure connection with a victim, without having to know and authenticate the long-term key shared between the victims, thus effectively bypassing Bluetooth's authentication mechani...

Apple on Monday rolled out security updates for  iOS ,  macOS ,  tvOS ,  watchOS , and  Safari  web browser to fix multiple vulnerabilities, including an actively exploited zero-day flaw in macOS Big Sur and expand patches for two previously disclosed zero-day flaws.  Tracked as CVE-2021-30713, the zero-day concerns a permissions issue in Apple's Transparency, Consent, and Control ( TCC ) framework in macOS that maintains a database of each user's consents. The iPhone maker acknowledged that the issue may have been exploited in the wild but stopped short of sharing specifics. The company noted that it rectified the problem with improved validation. However, in a separate report, mobile device management company Jamf said the bypass flaw was being actively exploited by XCSSET, a malware that's been out in the wild since August 2020 and known to propagate via modified  Xcode IDE projects  hosted on GitHub repositories and plant malicious p...

State-sponsored hackers affiliated with North Korea have been behind a slew of attacks on cryptocurrency exchanges over the past three years, new evidence has revealed. Attributing the attack with "medium-high" likelihood to the Lazarus Group (aka APT38 or Hidden Cobra), researchers from Israeli cybersecurity firm ClearSky said the campaign, dubbed " CryptoCore ," targeted crypto exchanges in Israel, Japan, Europe, and the U.S., resulting in the theft of millions of dollars worth of virtual currencies. The  findings  are a consequence of piecing together artifacts from a series of isolated but similar reports detailed by  F-Secure , Japanese CERT  JPCERT/CC , and  NTT Security  over the past few months. Since emerging on the scene in 2009,  Hidden Cobra  actors have used their offensive cyber capabilities to carry out espionage and cyber cryptocurrency heists against businesses and critical infrastructure. The adversary's targeting aligns wi...

As businesses move to a remote workforce, hackers have increased their activity to capitalize on new security holes. Cybercriminals often use unsophisticated methods that continue to be extremely successful. These include phishing emails to harvest credentials and gain easy access to business-critical environments. Hackers are also using ransomware to hold your data hostage, demanding a ransom payment in exchange for a decryption key that unlocks your stolen data.  When dealing with a cyberattack, there are practical steps you want to follow. What do these steps include? Quickly contain and isolate critical systems Report the hack to your customers and business stakeholders Engage the help of law enforcement Enact your disaster recovery and business continuity plans Analyze the attack, and remediate Quickly contain and isolate critical systems This first step is necessary: quickly contain and isolate critical systems. There is a chance that if you discover ransomware ...
