Every company needs help with cybersecurity. No CISO ever said, "I have everything I need and am fully confident that our organization is fully protected against breaches." This is especially true for small and mid-sized enterprises that don't have the luxury of enormous cybersecurity budgets and a deep bench of cybersecurity experts. To address this issue, especially for small and mid-sized enterprises, we've seen a sharp rise in Managed Detection and Response (MDR) services. MDR is essentially an outsourced cybersecurity expert service that monitors a company's environment and provides an improved ability to detect, investigate, and respond to threats. Think of it as augmenting your existing staff with a group of highly skilled cybersecurity experts. MDR Services Cynet recently published a new whitepaper that reviewed all of the services provided by their MDR team, which they refer to as "CyOps" [you can download the whitepaper here] . Interestin...

Cybersecurity researchers have taken the wraps off a new botnet hijacking Internet-connected smart devices in the wild to perform nefarious tasks, mostly DDoS attacks, and illicit cryptocurrency coin mining. Discovered by Qihoo 360's Netlab security team, the  HEH Botnet  — written in Go language and armed with a proprietary peer-to-peer (P2P) protocol, spreads via a brute-force attack of the Telnet service on ports 23/2323 and can execute arbitrary shell commands. The researchers said the HEH botnet samples discovered so far support a wide variety of CPU architectures, including x86(32/64), ARM(32/64), MIPS(MIPS32/MIPS-III), and PowerPC (PPC). The botnet, despite being in its early stages of development, comes with three functional modules: a propagation module, a local HTTP service module, and a P2P module. Initially downloaded and executed by a malicious Shell script named "wpqnbw.txt," the HEH sample then uses the Shell script to download rogue programs for all ...

Cybersecurity researchers have spotted a rare kind of potentially dangerous malware that targets a machine's booting process to drop persistent malware. The campaign involved the use of a compromised  UEFI  (or Unified Extensible Firmware Interface) containing a malicious implant, making it the  second known public case  where a UEFI rootkit has been used in the wild. According to  Kaspersky , the rogue UEFI firmware images were modified to incorporate several malicious modules, which were then used to drop malware on victim machines in a series of targeted cyberattacks directed against diplomats and members of an NGO from Africa, Asia, and Europe. Calling the malware framework " MosaicRegressor ," Kaspersky researchers Mark Lechtik, Igor Kuznetsov, and Yury Parshin said a telemetry analysis revealed several dozen victims between 2017 and 2019, all of whom had some ties to North Korea. UEFI is a firmware interface and a replacement for BIOS that improves s...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

As security professionals who have spent more than a few years in the industry, we know a good challenge when we see one. SaaS and cloud-based technologies are growing rapidly, offering organizations convenience and constant feature refreshes without the need to install and deploy software on-premises. However, even when referred to as 'a game-changer,' many organizations are still highly concerned by security breaches. Today, organizations have anywhere from 35-to literally hundreds of SaaS applications running. Slack, Office 365, Zoom, Zendesk, Salesforce, Hubspot, etc. These applications are at the core of modern enterprises, to the point where running a business without them would be nearly impossible, with the cost and time-saving benefits they provide enabling growth while conserving resources. SaaS applications are easy to use, scalable, and now, they even come with an impressive array of native security controls to secure sensitive corporate data. How to make the...

Cybersecurity researchers today disclosed details of security vulnerabilities found in popular antivirus solutions that could enable attackers to elevate their privileges, thereby helping malware sustain its foothold on the compromised systems. According to a report published by CyberArk researcher Eran Shimony today and shared with The Hacker News, the high privileges often associated with anti-malware products render them more vulnerable to exploitation via file manipulation attacks, resulting in a scenario where malware gains elevated permissions on the system. The bugs impact a wide range of antivirus solutions, including those from Kaspersky, McAfee, Symantec, Fortinet, Check Point, Trend Micro, Avira, and Microsoft Defender, each of which has been fixed by the respective vendor. Chief among the flaws is the ability to delete files from arbitrary locations, allowing the attacker to delete any file in the system, as well as a file corruption vulnerability that permits a bad ac...

Writing advanced malware for a threat actor requires different groups of people with diverse technical expertise to put them all together. But can the code leave enough clues to reveal the person behind it? To this effect, cybersecurity researchers on Friday detailed a new methodology to identify exploit authors that use their unique characteristics as a fingerprint to track down other exploits developed by them. By deploying this technique, the researchers were able to link 16 Windows local privilege escalation (LPE) exploits to two zero-day sellers "Volodya" (previously called "BuggiCorp") and "PlayBit" (or "luxor2008"). "Instead of focusing on an entire malware and hunting for new samples of the malware family or actor, we wanted to offer another perspective and decided to concentrate on these few functions that were written by an exploit developer," Check Point Research's Itay Cohen and Eyal Itkin noted. Fingerprinting an...

A hacking group known for its attacks in the Middle East, at least since 2017, has recently been found impersonating legitimate messaging apps such as Telegram and Threema to infect Android devices with a new, previously undocumented malware. "Compared to the versions documented in 2017, Android/SpyC23.A has extended spying functionality, including reading notifications from messaging apps, call recording and screen recording, and new stealth features, such as dismissing notifications from built-in Android security apps," cybersecurity firm ESET  said  in a Wednesday analysis. First detailed by Qihoo 360 in 2017 under the moniker  Two-tailed Scorpion (aka APT-C-23 or Desert Falcon), the mobile malware has been deemed "surveillanceware" for its abilities to spy on the devices of targeted individuals, exfiltrating call logs, contacts, location, messages, photos, and other sensitive documents in the process. In 2018, Symantec discovered a  newer variant  of t...

A Russian hacker who was found guilty of  hacking LinkedIn ,  Dropbox , and Formspring over eight years ago has finally been  sentenced  to 88 months in United States prison, that's more than seven years by a federal court in San Francisco this week. Yevgeniy Aleksandrovich Nikulin , 32, of Moscow hacked into servers belonging to three American social media firms, including LinkedIn, Dropbox, and now-defunct social-networking firm Formspring, and stole data on over 200 million users. Between March and July 2012, Nikulin hacked into the computers of LinkedIn,  Dropbox, and Formspring , and installed malware on them, which allowed him to remotely download user databases of over  117 Million LinkedIn  users and more than  68 Million Dropbox  users. According to the prosecutor, Nikulin also worked with unnamed co-conspirators of a Russian-speaking cybercriminal forum to sell customer data he stole as a result of his hacks. Besides hacking in...
