A Golang implementation of Cobalt Strike called Geacon is likely to garner the attention of threat actors looking to target Apple macOS systems. That's according to findings from SentinelOne, which observed an increase in the number of Geacon payloads appearing on VirusTotal in recent months. "While some of these are likely red-team operations, others bear the characteristics of genuine malicious attacks," security researchers Phil Stokes and Dinesh Devadoss  said  in a report. Cobalt Strike  is a well-known red teaming and adversary simulation tool developed by Fortra. Owing to its myriad capabilities, illegally cracked versions of the software have been abused by threat actors over the years. While post-exploitation activity associated with Cobalt Strike has primarily singled out Windows, such attacks against macOS are something of a rarity. In May 2022, software supply chain firm Sonatype  disclosed  details of a rogue Python package called " pymafka "...

Several security vulnerabilities have been disclosed in cloud management platforms associated with three industrial cellular router vendors that could expose operational technology (OT) networks to external attacks. The findings were presented by Israeli industrial cybersecurity firm OTORIO at the Black Hat Asia 2023 conference last week. "Industrial cellular routers and gateways are essential IIoT devices that provide connectivity for industrial applications, facilitating remote monitoring, control, and data exchange across various industries," OTORIO said. With gateways widely deployed in critical infrastructure sectors such as substations, water utilities, oil fields, and pipelines, weaknesses in these devices could have severe consequences, impacting availability and process safety. The 11 vulnerabilities discovered by the company allow "remote code execution and full control over hundreds of thousands of devices and OT networks - in some cases, even those not...

A new ransomware group known as  RA Group  has become the latest threat actor to leverage the leaked Babuk ransomware source code to spawn its own locker variant. The cybercriminal gang, which is said to have been operating since at least April 22, 2023, is rapidly expanding its operations, according to cybersecurity firm Cisco Talos. "To date, the group has compromised three organizations in the U.S. and one in South Korea across several business verticals, including manufacturing, wealth management, insurance providers and pharmaceuticals," security researcher Chetan Raghuprasad said in a report shared with The Hacker News. RA Group is no different from other ransomware gangs in that it launches double extortion attacks and runs a date leak site to apply additional pressure on victims into paying ransoms. The Windows-based binary employs  intermittent encryption  to speed up the process and evade detection, not to mention delete volume shadow copies and cont...

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...

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." ...
