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.
Ahead of presenting a long-term review of national security strategy in Parliament on Tuesday, U.K. Prime Minister Boris Johnson issued a statement calling for a boost to the country’s capacity to conduct cyberattacks on foreign adversaries.
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?
Russian hackers apparently weren't the only ones targeting SolarWinds customers. An attack last year by the Spiral hacking group, believed to be based in China, against one organization used malware that targeted a vulnerability in SolarWinds' Orion software, according to the Secureworks Counter Threat Unit.
Nearly four years after the WannaCry ransomware hit the world, targeting the EternalBlue vulnerability in Microsoft SMB version 1, security firms say the malware continues to be a top threat detected in the wild by endpoint security products. Why won't WannaCry just die?
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.
This edition of the ISMG Security Report features an analysis of key takeaways from the breaches tied to flaws in the Accellion File Transfer appliance. Also featured: Equifax CISO Jamil Farshchi on transforming supply chain security, plus an analysis of how "work from anywhere" is affecting cybersecurity.
Researchers with Microsoft and FireEye are disclosing additional malware used by the hacking group that targeted SolarWinds last December. These second-stage malware variants appear to have been deployed after organizations downloaded the "Sunburst" backdoor hidden in a software update.
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.
