Why High Tech Companies Struggle with SaaS Security

Why High Tech Companies Struggle with SaaS Security

May 15, 2023 SaaS Security
It's easy to think high-tech companies have a security advantage over other older, more mature industries. Most are unburdened by 40 years of legacy systems and software. They draw some of the world's youngest, brightest digital natives to their ranks, all of whom consider cybersecurity issues their entire lives. Perhaps it is due to their familiarity with technology that causes them to overlook SaaS security configurations. During the last Christmas holiday season, Slack had some private code stolen from its GitHub repository. According to Slack, the stolen code didn't impact production, and no customer data was taken. Still, the breach should serve as a warning sign to other tech companies. Stolen tokens allowed threat actors to access the GitHub instance and download the code. If this type of attack can happen to Slack on GitHub, it can happen to any high-tech company. Tech companies must take SaaS security seriously to prevent resources from leaking or being stolen. App Bre...
Researchers Uncover Powerful Backdoor and Custom Implant in Year-Long Cyber Campaign

Researchers Uncover Powerful Backdoor and Custom Implant in Year-Long Cyber Campaign

May 15, 2023 Cyber Threat / Malware
Government, aviation, education, and telecom sectors located in South and Southeast Asia have come under the radar of a new hacking group as part of a highly-targeted campaign that commenced in mid-2022 and continued into the first quarter of 2023. Symantec, by Broadcom Software, is tracking the activity under its insect-themed moniker  Lancefly , with the attacks making use of a "powerful" backdoor called Merdoor. Evidence gathered so far points to the custom implant being utilized as far back as 2018. The ultimate goal of the campaign, based on the tools and the victimology pattern, is assessed to be intelligence gathering. "The backdoor is used very selectively, appearing on just a handful of networks and a small number of machines over the years, with its use appearing to be highly targeted," Symantec  said  in an analysis shared with The Hacker News. "The attackers in this campaign also have access to an updated version of the ZXShell rootkit." ...
New 'MichaelKors' Ransomware-as-a-Service Targeting Linux and VMware ESXi Systems

New 'MichaelKors' Ransomware-as-a-Service Targeting Linux and VMware ESXi Systems

May 15, 2023 Linux / Hypervisor Jackpotting
A new ransomware-as-service (RaaS) operation called MichaelKors has become the latest file-encrypting malware to target Linux and  VMware ESXi systems  as of April 2023. The development points to cybercriminal actors increasingly setting their eyes on the ESXi, cybersecurity firm CrowdStrike said in a report shared with The Hacker News. "This trend is especially noteworthy given the fact that ESXi, by design, does not support third-party agents or AV software," the company said. "In fact, VMware goes as far as to claim it's not required. This, combined with the popularity of ESXi as a widespread and popular virtualization and management system, makes the hypervisor a highly attractive target for modern adversaries." The  targeting of VMware ESXi hypervisors  with ransomware to scale such campaigns is a technique known as  hypervisor jackpotting . Over the years, the approach has been adopted by several ransomware groups, including Royal. What's more...

CLR SqlShell Malware Targets MS SQL Servers for Crypto Mining and Ransomware

CLR SqlShell Malware Targets MS SQL Servers for Crypto Mining and Ransomware

May 15, 2023 Data Security / Cryptocurrency
Poorly managed Microsoft SQL (MS SQL) servers are the target of a new campaign that's designed to propagate a category of malware called  CLR SqlShell  that ultimately facilitates the deployment of cryptocurrency miners and ransomware. "Similar to web shell, which can be installed on web servers, SqlShell is a malware strain that supports various features after being installed on an MS SQL server, such as executing commands from threat actors and carrying out all sorts of malicious behavior," AhnLab Security Emergency response Center (ASEC)  said  in a report published last week. A stored procedure is a subroutine that contains a set of Structured Query Language (SQL) statements for use across multiple programs in a relational database management system (RDBMS). CLR (short for common language runtime) stored procedures – available in SQL Server 2005 and later – refer to  stored procedures  that are written in a .NET language such as C# or Visual Basic. ...
Former Ubiquiti Employee Gets 6 Years in Jail for $2 Million Crypto Extortion Case

Former Ubiquiti Employee Gets 6 Years in Jail for $2 Million Crypto Extortion Case

May 15, 2023 Cyber Crime / Network Security
A former employee of Ubiquiti has been  sentenced  to six years in jail after he pleaded guilty to posing as an anonymous hacker and a whistleblower in an attempt to extort almost $2 million worth of cryptocurrency while working at the company. Nickolas Sharp, 37, was arrested in December 2021 for using his insider access as a senior developer to steal confidential data and sending an anonymous email asking the network technology provider to pay 50 bitcoin (about $2 million at the time) in exchange for the siphoned information. Ubiquiti, however, didn't yield to the ransom attempt and instead looped in law enforcement, which eventually identified Sharp as the hacker after tracing a VPN connection to a Surfshark account purchased with his PayPal account. "Sharp repeatedly misused his administrative access to download gigabytes of confidential data from his employer," the U.S. Justice Department said, adding he "modified session file names to attempt to make it ap...

New Phishing-as-a-Service Platform Lets Cybercriminals Generate Convincing Phishing Pages

May 13, 2023
A new phishing-as-a-service (PhaaS or PaaS) platform named  Greatness  has been leveraged by cybercriminals to target business users of the Microsoft 365 cloud service since at least mid-2022, effectively lowering the bar to entry for phishing attacks. "Greatness, for now, is only focused on Microsoft 365 phishing pages, providing its affiliates with an attachment and link builder that creates highly convincing decoy and login pages," Cisco Talos researcher Tiago Pereira  said . "It contains features such as having the victim's email address pre-filled and displaying their appropriate company logo and background image, extracted from the target organization's real Microsoft 365 login page." Campaigns involving Greatness have mainly manufacturing, health care, and technology entities located in the U.S., the U.K., Australia, South Africa, and Canada, with a spike in activity detected in December 2022 and March 2023. Phishing kits like Greatness offer t...
XWorm Malware Exploits Follina Vulnerability in New Wave of Attacks

XWorm Malware Exploits Follina Vulnerability in New Wave of Attacks

May 12, 2023 Cyber Threat / Malware
Cybersecurity researchers have discovered an ongoing phishing campaign that makes use of a unique attack chain to deliver the  XWorm malware  on targeted systems. Securonix, which is tracking the activity cluster under the name  MEME#4CHAN , said some of the attacks have primarily targeted manufacturing firms and healthcare clinics located in Germany. "The attack campaign has been leveraging rather unusual meme-filled PowerShell code, followed by a heavily obfuscated XWorm payload to infect its victims," security researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov said in a new analysis shared with The Hacker News. The report builds on  recent findings  from Elastic Security Labs, which revealed the threat actor's reservation-themed lures to deceive victims into opening malicious documents capable of delivering XWorm and Agent Tesla payloads. The attacks begin with phishing attacks to distribute decoy Microsoft Word documents that, instead of using macr...
