Volexity regularly prioritizes memory forensics when responding to incidents. This strategy improves investigative capabilities in many ways across Windows, Linux, and macOS. This blog post highlights some specific ways memory forensics played a key role in determining how two zero-day vulnerabilities were being chained together to achieve unauthenticated remote code execution in Ivanti Connect Secure VPN devices.
Apple said the vulnerability, which is being exploited in the wild, allows malicious code to run on an affected device.
While most end users are well-acquainted with the dangers of traditional phishing attacks, such as those delivered via email or other media, a large proportion are likely unaware that Microsoft Teams chats could be a phishing vector. Most Teams activity is intra-organizational, but Microsoft enables External Access by default, which allows members of one organization to add users outside the organization to their Teams chats. Perhaps predictably, this feature has provided malicious actors a new avenue by which to exploit untrained or unaware users.
If you ever troubleshooted anything on Windows or investigated a suspicious event, you know that Windows store various types of events in Windows Event Log. An application crashed and you want to know more about it? Launch the Event Viewer and check the Application log. A service behaving strangely? See the System log. A user account got unexpectedly blocked? The Security log may reveal who or what blocked it.
All these events are getting stored to various logs through the Windows Event Log service. Unsurprisingly, this service's description says: "Stopping this service may compromise security and reliability of the system."
The Windows Event Log service performs many tasks. Not only is it responsible for writing events coming from various source to persistent file-based logs (residing in %SystemRoot%\System32\Winevt\Logs), it also provides structured access to these stored events through applications like Event Viewer. Furthermore, this service also performs "event forwarding" if you want your events sent to a central log repository like Splunk or Sumo Logic, an intrusion detection system or a SIEM server.
Therefore, Windows Event Log service plays an important role in many organizations' intrusion detection and forensic capabilities. And by extension, their compliance check boxes.
UNC4990 uses USB devices for initial infection, and is likely motivated by financial gain.
A takedown request said the GitHub account was “hosting and distributing leaks of internal code which poses significant risk to BINANCE.”
In this blog, we detail our investigation of the Kasseika ransomware and the indicators we found suggesting that the actors behind it have acquired access to the source code of the notorious BlackMatter ransomware.
The Qualys Threat Research Unit (TRU) has recently unearthed four significant vulnerabilities in the GNU C Library, a cornerstone for countless applications in the Linux environment.
Before diving into the specific details of the vulnerabilities discovered by the Qualys Threat Research Unit in the GNU C Library, it’s crucial to understand these findings’ broader impact and importance. The GNU C Library, or glibc, is an essential component of virtually every Linux-based system, serving as the core interface between applications and the Linux kernel. The recent discovery of these vulnerabilities is not just a technical concern but a matter of widespread security implications.
German police have confiscated 50,000 bitcoin worth $2.17 billion in the country's 'most extensive' cryptocurrency seizure ever, it said in a statement on Tuesday.
"This is the most extensive seizure of bitcoins by law enforcement authorities in the Federal Republic of Germany to date," police in the city of Dresden said.
The investigation was supported by the Federal Criminal Police Office (BKA), the FBI and a Munich-based forensic IT expert company, it said.
Following a recent and highly disruptive cyberattack on telecom carrier Orange España the cybersecurity community needs to rethink its approach to safeguarding the digital identity of staff involved in network engineering and IT infrastructure management. Orange España is the second-largest mobile operator in Spain. In early January, an attacker going by the alias ‘Snow’ hijacked Orange España’s RIPE Network Coordination Centre (NCC) account. RIPE is Europe’s regional Internet registry. After this initial breach, Snow sabotaged the telecommunications firm’s border gateway protocol (BGP) and resource public key infrastructure (RPKI) configurations.
Hundreds of compromised credentials of customers of RIPE, APNIC, AFRINIC, and LACNIC available on the dark web, Resecurity warns.
The U.S. government in recent months launched an operation to fight a pervasive Chinese hacking operation that successfully compromised thousands of internet-connected devices, according to two Western security officials and one person familiar with the matter.
The Justice Department and Federal Bureau of Investigation sought and received legal authorization to remotely disable aspects of the Chinese hacking campaign, the sources told Reuters.
