Tech giant Apple on Monday rolled out updates to remediate a zero-day flaw in iOS and iPadOS that it said has been actively exploited in the wild. The weakness, given the identifier CVE-2022-42827 , has been described as an out-of-bounds write issue in the Kernel, which could be abused by a rogue application to execute arbitrary code with the highest privileges. Successful exploitation of out-of-bounds write flaws, which typically occur when a program attempts to write data to a memory location that's outside of the bounds of what it is allowed to access, can result in corruption of data, a crash, or execution of unauthorized code. The iPhone maker said it addressed the bug with improved bounds checking, while crediting an anonymous researcher for reporting the vulnerability. As is usually the case with actively exploited zero-day flaws, Apple refrained from sharing more specifics about the shortcoming other than acknowledging that it's "aware of a report that this i...

Virtual Chief Information Security Officer (vCISO) services (also known as 'Fractional CISO' or 'CISO-as-a-Service') are growing in popularity, especially as growing cyber threats, tightening regulatory demands and strict cyber insurance requirements are driving small to medium-sized enterprises demand for strategic cybersecurity and compliance guidance and management. But vCISO services are labor intensive, require highly skilled experts, and are difficult to scale. So, how exactly do successful vCISO providers overcome these obstacles? When you want advice on how to overcome challenges, scale and expand, who better to go to than the people who have been there, seen it, and done it with success? In a new eBook, titled ' Top virtual CISOs share: 7 tips on how vCISO service providers can maximize services, increase revenues, and improve margins " ( Download here ), vCISO platform provider Cynomi interviewed some of America's top vCISO service providers (MS...

SideWinder, a prolific nation-state actor mainly known for targeting Pakistan military entities, compromised the official website of the National Electric Power Regulatory Authority (NEPRA) to deliver a tailored malware called  WarHawk . "The newly discovered WarHawk backdoor contains various malicious modules that deliver Cobalt Strike, incorporating new TTPs such as  KernelCallBackTable injection  and Pakistan Standard Time zone check in order to ensure a victorious campaign," Zscaler ThreatLabz  said . The threat group, also called APT-C-17, Rattlesnake, and Razor Tiger, is  suspected  to be an Indian state-sponsored actor, although a report from Kaspersky earlier this May acknowledged previous indicators that led to the attribution have since disappeared, making it challenging it to link the threat cluster to a specific nation. More than 1,000 attacks are said to have been  launched by the group  since April 2020, an indication of SideWin...

U.S. cybersecurity and intelligence agencies have published a joint advisory warning of attacks perpetrated by a cybercrime gang known as the  Daixin Team  primarily targeting the healthcare sector in the country. "The Daixin Team is a ransomware and data extortion group that has targeted the HPH Sector with ransomware and data extortion operations since at least June 2022," the agencies  said . The alert was published Friday by the Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Health and Human Services (HHS). Over the past four months, the group has been linked to multiple ransomware incidents in the Healthcare and Public Health (HPH) sector, encrypting servers related to electronic health records, diagnostics, imaging, and intranet services. It's also said to have exfiltrated personal identifiable information (PII) and patient health information (PHI) as part of a double extortion scheme to se...

The breach of LA Unified School District (LAUSD) highlights the prevalence of password vulnerabilities, as criminal hackers continue to use breached credentials in increasingly frequent ransomware attacks on education. The Labor Day weekend breach of LAUSD brought significant  districtwide disruptions to access to email , computers, and applications. It's unclear what student or employee data the attackers exfiltrated. There is a significant trend in ransomware breaches in education, a highly vulnerable sector. The transitory nature of students leaves accounts and passwords vulnerable. The open environments schools create to foster student exploration and the relative naivete in the sector regarding cybersecurity invite attacks.  The breach at LAUSD and what happened afterward Four days post-breach, reports came that criminals had offered credentials for accounts inside the school district's network  for sale on the dark web  months before the attack. The stolen...
