Large Majority of Netgear Router Models Are Vulnerable to Severe Security Flaw That Allow Remote Take-Overs by Hackers

A large majority, 79%. of Netgear router models are vulnerable to a severe security flaw that can let hackers take over devices remotely, two security researchers, Adam Nichols from cyber-security GRIMM and a security researcher going by the nickname of d4rkn3ss, working for Vietnamese internet service provider VNPT, discovered. The vulnerability impacts 758 different firmware versions that have been used on 79 Netgear routers across the years, with some firmware versions being first deployed on devices released as far back as 2007.

FBI Warns K12 Schools About Increase of Ransomware Attacks During Pandemic, Particularly Ransomware That Abuses RDP Connections

The US Federal Bureau of Investigation (FBI) sent out a security alert called a Private Industry Notification or PIN to K12 schools about the increase in ransomware attacks during the coronavirus (COVID-19) pandemic. The alert warned in particular about ransomware gangs that abuse RDP (remote desktop protocol) connections to break into school systems. The PIN said that “cyber actors are likely to increase targeting of K-12 schools during the COVID-19 pandemic because they represent an opportunistic target as more of these institutions transition to distance learning.” The Bureau said that 1,233 K12 schools were potentially targeted in 2019, with another 422 schools targeted in Q1 2020 alone.

Apple Announces Support for Encrypted DNS Communications in Upcoming Versions of iOS and macOS

Apple announced that the upcoming versions of its iOS and macOS operating systems would support the ability to handle encrypted DNS communications. Apple said that iOS 14 and macOS 11, set to be released this fall, will support both the DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) protocols. DoH and DoT allow a desktop, phone, or individual app to make DNS queries and receive DNS responses in an encrypted format thus preventing third-parties and malicious threat actors from tracking a user’s DNS queries and inferring the target’s web traffic destinations and patterns.

Apple Forced Certificate Authorities to Accept New Default Lifespan of 398 Days for TLS Certificates

A move by Apple in February to implement 398-day TLS certificate lifespans on its devices regardless of what certificate authorities in the industry-leading CA/B Forum thought of the issue has forced the certificate authority industry to accept a new default lifespan of 398 days for TLS certificates. Following Apple’s decision, Mozilla and Google have stated similar intentions to implement the same rule in their browsers. TLS lifespans started at eight years, and through the years, browser makers have chipped away at it, bringing it down to five, then to three, and then to two. Now, starting September 1, TLS lifespans started at eight years, and through the years, browser makers have chipped away at it, bringing it down to five, then to three, and then to two.

New Ransomware Strain Targeting macOS Users ‘EvilQuest’ Can Give Attacker Full Control Over Infected Host

A new ransomware strain targeting macOS users named OSX.EvilQuest differs from previous macOS ransomware threats because besides encrypting the victim’s files, it also installs a keylogger, a reverse shell, and steals cryptocurrency wallet-related files from infected hosts. With these capabilities, an attacker can maintain full control over an infected host. Some evidence indicates that EvilQuest has been distributed in the wild since the start of June 2020. Some researchers have found EvilQuest hidden inside pirated macOS software uploaded on torrent portals and online forums. Patrick Wardle of Objective-See, who has created several open-source macOS security tools, said that a tool he released in 2016, named RansomWhere, can detect and stop EvilQuest from running. Thomas Reed of Malwarebytes said that Malwarebytes for Mac was also updated to detect and stop this ransomware before it does any damage.

@campuscodi: Analysis of this new threat is now pouring in. There's an Objective-See blog post (https://objective-see.com/blog/blog_0x59.html) and Malwarebytes has published an analysis too (https://blog.malwarebytes.com/mac/2020/06/new-mac-ransomware-spreading-through-piracy/) SentinelOne is also working on one, as there's a lot of weird stuff inside this ransomware.
@campuscodi: The most interesting part about EvilQuest is that the ransomware tries (and fails) to modify files used by the Chrome updater and use them as a boot persistence mechanism.

New Attacks by Russian State-Sponsored Hacking Group Turla Uses Updated Version of ComRAT Malware Capable of Exfiltrating Antivirus Logs, Controlling Malware Using Arbitrary Gmail Inbox

New attacks carried out by Turla, one of Russia’s most advanced state-sponsored hacking groups, targeted a national parliament in the Caucasus and two Ministries of Foreign Affairs in Eastern Europe, researchers at ESET report. The attacks took place in January 2020 and represent the continuation of attacks by the group against diplomatic and military entities. The attacks stand out because they used updated versions of ComRAT malware, also known as Agent.BTZ, one of Turla’s oldest weapons.  This updated version of what is known as ComRAT v4 includes two new features, such as the ability to exfiltrate antivirus logs and the ability to control the malware using attachments sent to an arbitrary Gmail inbox. Despite the changes, the malware is still primarily used as a second-stage payload on already infected hosts.

Russian Hacking Group Turla Uses New Version of COMfun Malware That Relies on HTTP Status Codes to Target Diplomatic Groups Across Europe

Security researchers from Kaspersky have identified a new version of the COMpfun malware from the Russian hacking group Turla that controls infected hosts using a mechanism that relies on HTTP status codes. The attack has been deployed against diplomatic groups across Europe by the state-sponsored actor, which has a history of using innovative techniques. The COMpfun malware, which is a classic remote access trojan (RAT) that infects victims and then collects system data, logs keystrokes and takes screenshots of the user’s desktop. All collected data is exfiltrated to a remote C&C server. The new version used by Turla also adds the ability to monitor when USB removable devices are connected to an infected host, and then propagate itself to the new device as well as the new HTTP status code mechanism.
