Title: New Bluetooth Flaws Let Attackers Impersonate Legitimate Devices

Date Published: May 24, 2021


Excerpt: “Our attacks work even when the victims are using Bluetooth’s strongest security modes, e.g., SSP and Secure Connections. Our attacks target the standardized Bluetooth authentication procedure, and are therefore effective against any standard compliant Bluetooth device,” the researchers said.The Android Open Source Project (AOSP), Cisco, Cradlepoint, Intel, Microchip Technology, and Red Hat are among the identified vendors with products impacted by these security flaws. AOSP, Cisco, and Microchip Technology said they are currently working to mitigate the issues.”

Title: Apple Fixes MacOS Vulnerability Exploited by XCSSET Malware

Date Published: May 25, 2021


Excerpt: “This threat primarily spreads via Xcode projects and maliciously modified applications created from the malware. It is not yet clear how the threat initially enters these systems. Presumably, these systems would be primarily used by developers. These Xcode projects have been modified such that upon building, these projects would run a malicious code. This eventually leads to the main XCSSET malware being dropped and run on the affected system. Infected users are also vulnerable to having their credentials, accounts, and other vital data stolen.”

Title: Iranian Hacking Group Agrius Pretends to Encrypt Files for a Ransom, Destroys Them Instead

Date Published: May 25, 2021


Excerpt: “The group uses a combination of its own custom toolsets and readily available offensive security software to deploy either a destructive wiper or a custom wiper-turned-ransomware variant.   However, unlike ransomware groups such as Maze and Conti, it doesn’t appear that Agrius is purely motivated by money — instead, the use of ransomware is a new addition and a bolt-on to attacks focused on cyberespionage and destruction.”

Title: USB Drop Attack

Date Published: May 25, 2021


Excerpt: “This attack is so successful because it takes advantage of humans’ inherent curiosity and/or ability to support others. When there is a device lying around with possibly “juicy” details on it, humans can’t help but grab it to see what’s inside. A successful intruder takes advantage of a victim’s natural interest to convince them to take a USB gadget. When a gadget is taken, the contents are almost always going to be checked by the perpetrator. Attackers will have tempting files or file names within the device to capitalize on the human traits that drew them to the device in the first place.”

Date Published: May 24, 2021

Microsoft just released Windows 10 21H1 last week, but it was not met with much fanfare as it is not a very exciting release. Windows 10 21H2, also known as the Sun Valley update, is poised to be a much more feature-rich version, with a new UI refresh, DNS-over-HTTPS support, a modern disk management tool, new settings, and more.”

Title: Long-Lasting Malware Bot Phorpiex Adapts and Has New Ways of Deployment

Date Published: May 24, 2021


Excerpt: “Since recently, when it has been found out that Phorpiex has the capacity to disable Microsoft Defender, Microsoft specialists looked more closely into the botnet and found out that it is “modifying registry keys to disable firewall and antivirus popups or functionality, overriding proxy and browser settings, setting the loader and executables to run at startup, and adding these executables to the authorized application lists.”

Date Published: May 24, 2021


Excerpt: “CNA reported being victimized by a “cybersecurity attack” on March 23 that caused a network disruption and affected certain systems, including corporate email. The attack led the company to disconnect its systems, including taking down its website. CNA later confirmed it had been victimized by ransomware. But CNA has not confirmed it paid a ransom.
