In 2020, the pandemic tremendously impacted public-sector organisations all over the world. As every public-facing service organisation was forced to start pivoting to digital alternatives from the traditional “in-person & paper” model, a new set of challenges were created.
The digital transformation taking...
Threat detection and response is a core component of modern security programs, driving investment in tools to improve visibility, efficacy,
and efficiency. As organizations commit to and extend EDR, NDR, or other security analytics solutions in support of broad threat detection
and response programs, new...
Advanced attackers can evade detection by stealing credentials and masquerading as legitimate users. In response, security teams today must deploy multiple – often siloed – detection and response tools.
The problem is that each tool only provides a narrow view of one data source, forcing analysts to manually...
Security teams face a dizzying array of threats, from ransomware and
cyberespionage to fileless attacks and damaging data breaches. However,
the biggest headache for many security analysts is not the endless number
of risks that dominate news headlines, but rather the repetitive tasks they
must perform every day...
Protecting your endpoints requires a much more holistic approach than simply blocking known
malware. Adversaries today create countless variants of malware and use obfuscation techniques
to evade signature detection.
They can turn your own resources against you, converting legitimate
endpoint applications into...
Criminals continue to target on-premises Microsoft Exchange servers that have not yet been updated with four critical patches, including for a ProxyLogon flaw, which is now being targeted by Black Kingdom ransomware. One expert describes the attack code as being "rudimentary and amateurish" but still a threat.
There has been a spike in web shells being detected as ransomware gangs and other attackers increasingly target vulnerable on-premises Microsoft Exchange servers following publication of proof-of-concept attack code for ProxyLogon, which is one of four zero-day flaws patched by Microsoft in early March.
This edition of the ISMG Security Report features an analysis of the Microsoft Exchange on-premises server hacks – from who might have leaked the vulnerability exploits to how ransomware gangs are taking advantage of the flaws. Also featured: Tackling the cybercrime business model; assessing "zero trust."
As the Biden administration makes final preparations to respond to the attacks against SolarWinds, it's been confronted by a second major cyberthreat: the hacking of Microsoft Exchange servers throughout the U.S. The response to this incident, however, will likely be much different.
A report by analyst firm Research in Action reveals the importance of adopting a continuous application performance management (CAPM) solution that continuously identifies performance and availability issues to provide proactive detection and diagnosis. The firm’s report, 2019 Vendor Selection Matrix for Continuous...
It has been an open question as to how a half-dozen hacking groups began exploiting Exchange servers in an automated fashion in the days leading up to Microsoft's patches. But there are strong signs that the exploit code leaked, and the question now is: Who leaked it?
The latest edition of the ISMG Security Report features cybercrime deterrence lessons learned from the disruption of the Emotet botnet operation. Also featured: An update on attacks tied to Microsoft Exchange flaw exploits; a discussion of the need to update business continuity plans.
Computer security researchers have acquired an enormous list of compromised email servers from the perpetrators of the mass Microsoft Exchange compromises. But a big question looms: How bad is this situation going to get?
Just days after Microsoft disclosed four serious flaws in Microsoft Exchange email servers, attackers are going on a wide hunt for vulnerable machines, some security experts say. The flaws could be exploited for creating backdoors for email accounts or installing ransomware and cryptominers.
Microsoft issued emergency software patches on Tuesday for four zero-day vulnerabilities in its Exchange email server. The alarming vulnerabilities could allow a remote attacker into Exchange and possibly enable further lateral movement.
