REvil ransomware - what you need to know

REvil is an ambitious criminal ransomware-as-a-service (RAAS) enterprise that first came to prominence in April 2019, following the demise of another ransomware gang GandCrab. The REvil group is also known sometimes by other names such as Sodin and Sodinokibi. REvil has gained a reputation for attempting to extort far larger payments from its corporate victims than that typically seen in other attacks.

How to Future Proof Your System Against a Zero Day Exploit

Earlier this year, Kaspersky researchers discovered a zero day exploit hidden in Desktop Windows Manager. The exploit, designated as CVE-2021-28310, is known as an escalation of privilege (EoP) exploit, which allows attackers to gain access or a higher-level user permission to systems and platforms than an administrator would permit. Though patches have since been released, it’s not yet known how extensive the damage from this zero day exploit is yet.

Open Banking Opportunities to Retain and Delight Existing Customers

The banking landscape is changing. The days of walled garden banking where customers can’t see or access information from all their financial institutions in one place are coming to a close. For banks, and the entire financial services industry, open banking isn’t a threat but a customer service opportunity. Instead of putting barriers between customers and their financial information at other institutions, banks can offer value-added insights across accounts and institutions.

Genesis Market: A Hacker's Haven of Stolen Credentials

Netacea’s Threat Research team works diligently to keep a close eye on emerging bot threats, ensuring we stay one step ahead of cybercriminals and hackers. The team recently completed an exclusive investigation into the Genesis Market, an illegal online marketplace for stolen credentials. While many underground markets for stolen credentials operate from the anonymity of the dark web, Genesis Market is accessible from the open web.

Streamlining Vulnerability Management with Splunk Phantom

Vulnerabilities are weaknesses in the security infrastructure that bad actors can exploit to gain unauthorized access to a private network. It is nearly impossible for security analysts to patch 100% of the vulnerabilities identified on any given day, but a vulnerability management plan can ensure that the highest risk vulnerabilities (those that are most likely to cause a data breach), will be addressed immediately.

How to Plan a Threat Hunt: Using Log Analytics to Manage Data in Depth

Security analysts have long been challenged to keep up with growing volumes of increasingly sophisticated cyberattacks, but their struggles have recently grown more acute. Only 46% of security operations leaders are satisfied with their team’s ability to detect threats, and 82% of decision-makers report that their responses to threats are mostly or completely reactive — a shortcoming they’d like to overcome.

Detect unauthorized third parties in your AWS account

Detecting when an unauthorized third party is accessing your AWS account is critical to ensuring your account remains secure. For example, an attacker may have gained access to your environment and created a backdoor to maintain persistence within your environment. Another common (and more frequent) type of unauthorized access can happen when a developer sets up a third-party tool and grants it access to your account to monitor your infrastructure for operations or optimize your bill.

Bridging the Cybersecurity frontier: SaaS

Software as a service (SaaS) is one of the most important parts of the modern digital business. Unfortunately, when it comes to cybercrime, it can also be one of the weakest. The Cybersecurity newsletter, The Hacker News, have highlighted this in detail, noting interest from across the digital industry in addressing the holes created by misconfigured SaaS setups.

Critical Pulse Connect Secure SSL VPN Vulnerability Exploited

In yet another example of VPN appliance vulnerabilities being actively exploited by threat actors, 20 April 2021 saw the publication of a critical Pulse Connect Secure (PCS) SSL VPN appliance vulnerability, CVE-2021-22893, allowing an authentication bypass that leads to an unauthenticated threat actor gaining the ability to remotely execute arbitrary code on a PCS gateway.
