The U.S. government on Tuesday unsealed charges against a Chinese national for allegedly breaking into thousands of Sophos firewall devices globally in 2020. Guan Tianfeng (aka gbigmao and gxiaomao), who is said to have worked at Sichuan Silence Information Technology Company, Limited, has been charged with conspiracy to commit computer fraud and conspiracy to commit wire fraud. Guan has been accused of developing and testing a zero-day security vulnerability used to conduct the attacks against Sophos firewalls. "Guan Tianfeng is wanted for his alleged role in conspiring to access Sophos firewalls without authorization, cause damage to them, and retrieve and exfiltrate data from both the firewalls themselves and the computers behind these firewalls," the U.S. Federal Bureau of Investigation (FBI) said . "The exploit was used to infiltrate approximately 81,000 firewalls." The then-zero-day vulnerability in question is CVE-2020-12271 (CVSS score: 9.8), a severe S...

Now-patched security flaws impacting Progress Kemp LoadMaster and VMware vCenter Server have come under active exploitation in the wild, it has emerged. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added CVE-2024-1212 (CVSS score: 10.0), a maximum-severity security vulnerability in Progress Kemp LoadMaster to its Known Exploited Vulnerabilities ( KEV ) catalog. It was addressed by Progress Software back in February 2024 . "Progress Kemp LoadMaster contains an OS command injection vulnerability that allows an unauthenticated, remote attacker to access the system through the LoadMaster management interface, enabling arbitrary system command execution," the agency said. Rhino Security Labs, which discovered and reported the flaw, said successful exploitation enables command execution on LoadMaster should an attacker have access to the administrator web user interface, granting them full access to the load balancer. CISA's addition of ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

In an unusually specific campaign, users searching about the legality of Bengal Cats in Australia are being targeted with the GootLoader malware. "In this case, we found the GootLoader actors using search results for information about a particular cat and a particular geography being used to deliver the payload: 'Are Bengal Cats legal in Australia?,'" Sophos researchers Trang Tang, Hikaru Koike, Asha Castle, and Sean Gallagher said in a report published last week. GootLoader , as the name implies, is a malware loader that's typically distributed using search engine optimization (SEO) poisoning tactics for initial access. Specifically, the malware is deployed onto victim machines when searching for certain terms like legal documents and agreements on search engines like Google surface booby-trapped links pointing to compromised websites that host a ZIP archive containing a JavaScript payload. Once installed, it makes way for a second-stage malware, often an...

A trio of threat activity clusters linked to China has been observed compromising more government organizations in Southeast Asia as part of a renewed state-sponsored operation codenamed Crimson Palace , indicating an expansion in the scope of the espionage effort. Cybersecurity firm Sophos, which has been monitoring the cyber offensive, said it comprises three intrusion sets tracked as Cluster Alpha (STAC1248), Cluster Bravo (STAC1870), and Cluster Charlie (STAC1305). STAC is an abbreviation for "security threat activity cluster." "The attackers consistently used other compromised organizational and public service networks in that region to deliver malware and tools under the guise of a trusted access point," security researchers Mark Parsons, Morgan Demboski, and Sean Gallagher said in a technical report shared with The Hacker News. A noteworthy aspect of the attacks is that it entails the use of an unnamed organization's systems as a command-and-control ...

An advanced persistent threat (APT) actor known as  Dragon Breath  has been observed adding new layers of complexity to its attacks by adopting a novel  DLL side-loading  mechanism. "The attack is based on a classic side-loading attack, consisting of a clean application, a malicious loader, and an encrypted payload, with various modifications made to these components over time," Sophos researcher Gabor Szappanos  said . "The latest campaigns add a twist in which a first-stage clean application 'side'-loads a second clean application and auto-executes it. The second clean application side-loads the malicious loader DLL. After that, the malicious loader DLL executes the final payload." Operation Dragon Breath, also tracked under the names APT-Q-27 and Golden Eye, was  first   documented  by QiAnXin in 2020, detailing a watering hole campaign designed to trick users into downloading a trojanized Windows installer for Telegram. A  subsequen...

Security software company Sophos has released a patch update for its firewall product after it was discovered that attackers were exploiting a new critical zero-day vulnerability to attack its customers' network. The issue, tracked as  CVE-2022-3236  (CVSS score: 9.8), impacts Sophos Firewall v19.0 MR1 (19.0.1) and older and concerns a code injection vulnerability in the User Portal and Webadmin components that could result in remote code execution. The company  said  it "has observed this vulnerability being used to target a small set of specific organizations, primarily in the South Asia region," adding it directly notified these entities. As a workaround, Sophos is recommending that users take steps to ensure that the User Portal and Webadmin are not exposed to WAN. Alternatively, users can update to the latest supported version - v19.5 GA v19.0 MR2 (19.0.2) v19.0 GA, MR1, and MR1-1 v18.5 MR5 (18.5.5) v18.5 GA, MR1, MR1-1, MR2, MR3, and MR4 v18.0 MR3, ...

Cybersecurity firm Sophos on Monday warned that a recently patched critical security vulnerability in its firewall product is being actively exploited in real-world attacks. The flaw, tracked as  CVE-2022-1040 , is rated 9.8 out of 10 on the CVSS scoring system and impacts Sophos Firewall versions 18.5 MR3 (18.5.3) and older. It relates to an authentication bypass vulnerability in the User Portal and Webadmin interface that, if successfully weaponized, allows a remote attacker to execute arbitrary code. "Sophos has observed this vulnerability being used to target a small set of specific organizations primarily in the South Asia region," the company  noted  in a revised advisory published Monday. "We have informed each of these organizations directly." The flaw has been addressed in a hotfix that's automatically installed for customers who have the " Allow automatic installation of hotfixes " setting enabled. As a workaround, Sophos is recommending...

In a sign that threat actors continuously shift tactics and update their defensive measures, the operators of the SolarMarker information stealer and backdoor have been found leveraging stealthy Windows Registry tricks to establish long-term persistence on compromised systems. Cybersecurity firm Sophos, which spotted the new behavior, said that the remote access implants are still being detected on targeted networks despite the campaign witnessing a decline in November 2021. Boasting of information harvesting and backdoor capabilities, the .NET-based malware has been linked to at least three different attack waves in 2021. The first set,  reported in April , took advantage of search engine poisoning techniques to trick business professionals into visiting sketchy Google sites that installed SolarMarker on the victim's machines. Then in August, the malware was  observed  targeting healthcare and education sectors with the goal of gathering credentials and sensitive in...

Hackers are planning to increase data security attacks via applications on social networking websites this Christmas, according to an expert. Earlier this month, IT security firm Sophos traced the history of malware and viruses created over the Christmas period from 1987 until 2009. The blog post revealed that, although some were relatively harmless festive pranks, more cyberattacks over the holidays could have serious repercussions for computer users. Rik Ferguson, senior security analyst at Trend Micro, stated that hackers conduct such attacks annually. "Criminals absolutely do, every year without fail, conduct campaigns designed to take advantage of people's willingness to search for and click on links relating to Christmas activity, whether that's through phishing campaigns or sending social engineering emails masquerading as Christmas cards," he said. Mr. Ferguson added that apps on social networking sites had "come of age as an attack platform" and...
