Apple Delays Plans to Scan Devices for Child Abuse Images After Privacy Backlash

Apple Delays Plans to Scan Devices for Child Abuse Images After Privacy Backlash

Sep 04, 2021
Apple is temporarily hitting the pause button on its  controversial plans  to screen users' devices for child sexual abuse material (CSAM) after receiving sustained blowback over worries that the tool could be weaponized for mass surveillance and erode the privacy of users. "Based on feedback from customers, advocacy groups, researchers, and others, we have decided to take additional time over the coming months to collect input and make improvements before releasing these critically important child safety features," the iPhone maker  said  in a statement on its website. The announcement, however, doesn't make it clear as to the kind of inputs it would be gathering, the nature of changes it aims to devise, or how it intends to implement the system in a way that mitigates the privacy and security concerns that could arise once it's deployed. The changes were originally slated to go live with iOS 15 and macOS Monterey later this year, starting with the U.S. In ...
Microsoft Says Chinese Hackers Were Behind SolarWinds Serv-U SSH 0-Day Attack

Microsoft Says Chinese Hackers Were Behind SolarWinds Serv-U SSH 0-Day Attack

Sep 04, 2021
Microsoft has shared technical details about a now-fixed, actively exploited critical security vulnerability affecting SolarWinds Serv-U managed file transfer service that it has attributed with "high confidence" to a threat actor operating out of China. In mid-July, the Texas-based company  remedied  a remote code execution flaw ( CVE-2021-35211 ) that was rooted in Serv-U's implementation of the Secure Shell (SSH) protocol, which could be abused by attackers to run arbitrary code on the infected system, including the ability to install malicious programs and view, change, or delete sensitive data. "The Serv-U SSH server is subject to a pre-auth remote code execution vulnerability that can be easily and reliably exploited in the default configuration," Microsoft Offensive Research and Security Engineering team said in a  detailed write-up  describing the exploit. "An attacker can exploit this vulnerability by connecting to the open SSH port and sendin...

U.S. Cyber Command Warns of Ongoing Attacks Exploiting Atlassian Confluence Flaw

Sep 04, 2021
The U.S. Cyber Command on Friday warned of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments that could be abused by unauthenticated attackers to take control of a vulnerable system. "Mass exploitation of Atlassian Confluence  CVE-2021-26084  is ongoing and expected to accelerate," the Cyber National Mission Force (CNMF)  said  in a tweet. The warning was also echoed by the U.S. Cybersecurity and Infrastructure Security Agency ( CISA ) and  Atlassian itself  in a series of independent advisories. Bad Packets  noted  on Twitter it "detected mass scanning and exploit activity from hosts in Brazil, China, Hong Kong, Nepal, Romania, Russia and the U.S. targeting Atlassian Confluence servers vulnerable to remote code execution." Atlassian Confluence is a widely popular web-based documentation service that allows teams to create, collaborate, and organiz...
This New Malware Family Using CLFS Log Files to Avoid Detection

This New Malware Family Using CLFS Log Files to Avoid Detection

Sep 03, 2021
Cybersecurity researchers have disclosed details about a new malware family that relies on the Common Log File System ( CLFS ) to hide a second-stage payload in registry transaction files in an attempt to evade detection mechanisms. FireEye's Mandiant Advanced Practices team, which made the discovery, dubbed the malware PRIVATELOG , and its installer, STASHLOG . Specifics about the identities of the threat actor or their motives remain unclear. Although the malware is yet to be detected in real-world attacks aimed at customer environments or be spotted launching any second-stage payloads, Mandiant suspects that PRIVATELOG could still be in development, the work of a researcher, or deployed as part of a highly targeted activity. CLFS is a general-purpose logging subsystem in Windows that's accessible to both kernel-mode as well as user-mode applications such as database systems, OLTP systems, messaging clients, and network event management systems for building and sharing h...
FIN7 Hackers Using Windows 11 Themed Documents to Drop Javascript Backdoor

FIN7 Hackers Using Windows 11 Themed Documents to Drop Javascript Backdoor

Sep 03, 2021
A recent wave of spear-phishing campaigns leveraged weaponized Windows 11 Alpha-themed Word documents with Visual Basic macros to drop malicious payloads, including a JavaScript implant, against a point-of-sale (PoS) service provider located in the U.S. The attacks, which are believed to have taken place between late June to late July 2021, have been attributed with "moderate confidence" to a financially motivated threat actor dubbed FIN7, according to researchers from cybersecurity firm Anomali. "The specified targeting of the Clearmind domain fits well with FIN7's preferred modus operandi," Anomali Threat Research  said  in a technical analysis published on September 2. "The group's goal appears to have been to deliver a variation of a JavaScript backdoor used by FIN7 since at least 2018." An Eastern European group active since at least mid-2015, FIN7 has a checkered history of targeting restaurant, gambling, and hospitality industries in th...

Cisco Issues Patch for Critical Enterprise NFVIS Flaw — PoC Exploit Available

Sep 03, 2021
Cisco has patched a critical security vulnerability impacting its Enterprise Network Function Virtualization Infrastructure Software (NFVIS) that could be exploited by an attacker to take control of an affected system. Tracked as  CVE-2021-34746 , the weakness has been rated 9.8 out of a maximum of 10 on the Common Vulnerability Scoring System (CVSS) and could allow a remote attacker to circumvent authentication and log in to a vulnerable device as an administrator. The network equipment maker said it's aware of a publicly available proof-of-concept (PoC) exploit code targeting the vulnerability, but added it's not detected any successful weaponization attempts in the wild. CVE-2021-34746 issue is caused due to an incomplete validation of user-supplied input that's passed to an authentication script during the sign-in process, enabling an attacker to inject parameters into an authentication request. "A successful exploit could allow the attacker to bypass authenti...
What is AS-REP Roasting attack, really?

What is AS-REP Roasting attack, really?

Sep 02, 2021
Microsoft's Active Directory is  said to be used by 95%  of Fortune 500. As a result, it is a prime target for attackers as they look to gain access to credentials in the organization, as compromised credentials provide one of the easiest ways for hackers to access your data. A key authentication technology that underpins Microsoft Active Directory is Kerberos. Unfortunately, hackers use many different attacks against Active Directory's implementation of the Kerberos authentication protocol. One of those is AS-REP Roasting. So what is AS-REP Roasting, and how can businesses protect themselves? What is Active Directory Kerberos? Kerberos was originally developed by the Massachusetts Institute of Technology (MIT) and centered around using tickets to establish trust. Microsoft's implementation of Kerberos found in Active Directory is based on Kerberos Network Authentication Service (V5) as defined in  RFC 4120 . However, Microsoft has added to and enhanced Kerberos with ...

WhatsApp Photo Filter Bug Could Have Exposed Your Data to Remote Attackers

Sep 02, 2021
A now-patched high-severity security vulnerability in WhatApp's image filter feature could have been abused to send a malicious image over the messaging app to read sensitive information from the app's memory. Tracked as  CVE-2020-1910  (CVSS score: 7.8), the flaw concerns an out-of-bounds read/write and stems from applying specific image filters to a rogue image and sending the altered image to an unwitting recipient, thereby enabling an attacker to access valuable data stored the app's memory. "A missing bounds check in WhatsApp for Android prior to v2.21.1.13 and WhatsApp Business for Android prior to v2.21.1.13 could have allowed out-of-bounds read and write if a user applied specific image filters to a specially-crafted image and sent the resulting image," WhatsApp  noted  in its advisory published in February 2021. Cybersecurity firm Check Point Research, which disclosed the issue to the Facebook-owned platform on November 10, 2020, said it was able to...
Is Traffic Mirroring for NDR Worth the Trouble? We Argue It Isn't

Is Traffic Mirroring for NDR Worth the Trouble? We Argue It Isn't

Sep 02, 2021
Network Detection & Response (NDR) is an emerging technology developed to close the blind security spots left by conventional security solutions, which hackers exploited to gain a foothold in target networks. Nowadays, enterprises are using a plethora of security solutions to protect their network from cyber threats. The most prominent ones are Firewalls, IPS/IDS, SIEM, EDR, and XDR (which combines the functionality of EDR and SIEM). However, all these solutions suffer from security gaps that prevent them from stopping advanced cyber-attacks efficiently.  NDR was developed based on Intrusion Detection System (IDS). An IDS solution is installed on the network perimeter and monitors the network traffic for suspicious activities. IDS systems suffer from many downsides that make them inefficient in stopping modern cyber-attacks: IDS use signature-based detection techniques to discover abnormal activities, making them unable to spot unknown attacks. In addition, IDS systems tri...
Chinese Authorities Arrest Hackers Behind Mozi IoT Botnet Attacks

Chinese Authorities Arrest Hackers Behind Mozi IoT Botnet Attacks

Sep 02, 2021
The operators of the Mozi IoT botnet have been taken into custody by Chinese law enforcement authorities, nearly two years after the malware emerged on the threat landscape in September 2019. News of the arrest, which originally  happened  in June, was  disclosed  by researchers from Netlab, the network research division of Chinese internet security company Qihoo 360, earlier this Monday, detailing its involvement in the operation. "Mozi uses a P2P [peer-to-peer] network structure, and one of the 'advantages' of a P2P network is that it is robust, so even if some of the nodes go down, the whole network will carry on, and the remaining nodes will still infect other vulnerable devices, that is why we can still see Mozi spreading," said Netlab, which spotted the botnet for the first time in late 2019. The development also comes less than two weeks after Microsoft Security Threat Intelligence Center  revealed  the botnet's new capabilities that enable it t...
