Microsoft Finds 'BadAlloc' Flaws Affecting Wide-Range of IoT and OT Devices

Microsoft Finds 'BadAlloc' Flaws Affecting Wide-Range of IoT and OT Devices

Apr 30, 2021
Microsoft researchers on Thursday disclosed two dozen vulnerabilities affecting a wide range of Internet of Things (IoT) and Operational Technology (OT) devices used in industrial, medical, and enterprise networks that could be abused by adversaries to execute arbitrary code and even cause critical systems to crash. "These remote code execution (RCE) vulnerabilities cover more than 25 CVEs and potentially affect a wide range of domains, from consumer and medical IoT to Industrial IoT, Operational Technology, and industrial control systems,"  said  Microsoft's 'Section 52' Azure Defender for IoT research group. The flaws have been collectively named " BadAlloc ," for they are rooted in standard  memory allocation functions  spanning widely used real-time operating systems (RTOS), embedded software development kits (SDKs), and C standard library (libc) implementations. A lack of proper input validations associated with these memory allocation functions ...
A New Slack channel for Cybersecurity Leaders Outside of the Fortune 2000

A New Slack channel for Cybersecurity Leaders Outside of the Fortune 2000

Apr 30, 2021
Perhaps due to the nature of the position, the InfoSec leadership roles tend to be solitary ones. CISOs, or their equivalent decision-makers in organizations without the role, have so many constant drains on their attention – keeping their knowledge fresh, building plans to secure their organizations further – that they often find themselves on an island. It's even more challenging for organizations outside the Fortune 2000 that are resource-constrained. Security leaders are expected to know everything and often don't have anyone inside their organization with whom to bounce ideas or even go to for advice. When a crisis arises, they must often go with their gut or guess at the best solution based on their own experiences. Security leaders could often use advice but don't have an outlet for it. Chris Roberts, Chief Security Strategist at Cynet Security, offers a new Slack-based community for InfoSec leaders ( register here ) as a solution. The new InfoSec Leaders Community will fea...
Passwordstate Warns of Ongoing Phishing Attacks Following Data Breach

Passwordstate Warns of Ongoing Phishing Attacks Following Data Breach

Apr 30, 2021
Click Studios, the Australian software firm which confirmed a  supply chain attack  affecting its Passwordstate password management application, has warned customers of an ongoing phishing attack by an unknown threat actor. "We have been advised a bad actor has commenced a phishing attack with a small number of customers having received emails requesting urgent action," the company  said  in an updated advisory released on Wednesday. "These emails are not sent by Click Studios." Last week, Click Studios said attackers had employed sophisticated techniques to compromise Passwordstate's update mechanism, using it to drop malware on user computers. Only customers who performed In-Place Upgrades between April 20, 8:33 PM UTC, and April 22, 0:30 AM UTC are said to be affected. While Passwordstate serves about 29,000 customers, the Adelaide-based firm maintained that the total number of impacted customers is very low. It's also urging users to refrain from po...

A New PHP Composer Bug Could Enable Widespread Supply-Chain Attacks

Apr 29, 2021
The maintainers of Composer, a package manager for PHP, have shipped an update to address a critical vulnerability that could have allowed an attacker to execute arbitrary commands and "backdoor every PHP package," resulting in a supply-chain attack. Tracked as CVE-2021-29472, the security issue was discovered and reported on April 22 by researchers from  SonarSource , following which a hotfix was deployed less than 12 hours later. "Fixed command injection vulnerability in HgDriver/HgDownloader and hardened other VCS drivers and downloaders," Composer  said  its  release notes  for versions 2.0.13 and 1.10.22 published on Wednesday. "To the best of our knowledge the vulnerability has not been exploited." Composer  is billed as a tool for dependency management in PHP, enabling easy installation of packages relevant to a project. It also allows users to install PHP applications that are available on  Packagist , a repository that aggregates all publ...

Chinese Hackers Attacking Military Organizations With New Backdoor

Chinese Hackers Attacking Military Organizations With New Backdoor

Apr 29, 2021
Bad actors with suspected ties to China have been behind a wide-ranging cyberespionage campaign targeting military organizations in Southeast Asia for nearly two years, according to new research. Attributing the attacks to a threat actor dubbed " Naikon APT ," cybersecurity firm Bitdefender laid out the ever-changing tactics, techniques, and procedures adopted by the group, including weaving new backdoors named "Nebulae" and "RainyDay" into their data-stealing missions. The malicious activity is said to have been conducted between June 2019 and March 2021. "In the beginning of the operation the threat actors used Aria-Body loader and Nebulae as the first stage of the attack," the researchers  said . "Starting with September 2020, the threat actors included the RainyDay backdoor in their toolkit. The purpose of this operation was cyberespionage and data theft." Naikon (aka Override Panda, Lotus Panda, or Hellsing) has a track recor...
Researchers Uncover Stealthy Linux Malware That Went Undetected for 3 Years

Researchers Uncover Stealthy Linux Malware That Went Undetected for 3 Years

Apr 29, 2021
A previously undocumented Linux malware with backdoor capabilities has managed to stay under the radar for about three years, allowing the threat actor behind the operation to harvest and exfiltrate sensitive information from infected systems. Dubbed " RotaJakiro " by researchers from Qihoo 360 NETLAB, the backdoor targets Linux X64 machines, and is so named after the fact that "the family uses rotate encryption and behaves differently for root/non-root accounts when executing." The findings come from an analysis of a  malware sample  it detected on March 25, although early versions appear to have been uploaded to VirusTotal as early as May 2018. A  total  of  four   samples  have been found to date on the database, all of which remain undetected by most anti-malware engines. As of writing, only seven security vendors flag the latest version of the malware as malicious. "At the functional level, RotaJakiro first determines whether the user is roo...
Cybercriminals Widely Abusing Excel 4.0 Macro to Distribute Malware

Cybercriminals Widely Abusing Excel 4.0 Macro to Distribute Malware

Apr 28, 2021
Threat actors are increasingly adopting  Excel 4.0 documents  as an initial stage vector to distribute malware such as  ZLoader  and Quakbot, according to new research. The findings come from an analysis of 160,000 Excel 4.0 documents between November 2020 and March 2021, out of which more than 90% were classified as malicious or suspicious. "The biggest risk for the targeted companies and individuals is the fact that security solutions still have a lot of problems with detecting malicious Excel 4.0 documents, making most of these slip by conventional signature based detections and analyst written YARA rules," researchers from ReversingLabs said in a report  published today . Excel 4.0 macros (XLM), the precursor to Visual Basic for Applications (VBA), is a legacy feature incorporated in Microsoft Excel for backward compatibility reasons. Microsoft warns in its  support document  that enabling all macros can cause "potentially dangerous code" to ...
