Backdoor Found in Popular Server Management Software used by Hundreds of Companies

Backdoor Found in Popular Server Management Software used by Hundreds of Companies

Aug 16, 2017
Cyber criminals are becoming more adept, innovative, and stealthy with each passing day. They are now adopting more clandestine techniques that come with limitless attack vectors and are harder to detect. Recently, cyber crooks managed to infiltrate the update mechanism for a popular server management software package and altered it to include an advanced backdoor, which lasts for at least 17 days until researchers discovered it. Dubbed ShadowPad , the secret backdoor gave attackers complete control over networks hidden behind legit cryptographically signed software sold by NetSarang —used by hundreds of banks, media firms, energy companies, and pharmaceutical firms, telecommunication providers, transportation and logistics and other industries—for 17 days starting last month. Important Note — If you are using any of the affected product (listed below), we highly recommend you stop using it until you update them. Hacker Injected Backdoor Through Software Update Mechani...

New Evidence Suggests SolarWinds' Codebase Was Hacked to Inject Backdoor

Dec 16, 2020
The investigation into how the attackers managed to compromise SolarWinds' internal network and poison the company's software updates is still underway, but we may be one step closer to understanding what appears to be a very meticulously planned and highly-sophisticated supply chain attack. A new report published by ReversingLabs today and shared in advance with The Hacker News has revealed that the operators behind the  espionage campaign  likely managed to compromise the software build and code signing infrastructure of SolarWinds Orion platform as early as October 2019 to deliver the malicious backdoor through its software release process. "The source code of the affected library was directly modified to include malicious backdoor code, which was compiled, signed, and delivered through the existing software patch release management system," ReversingLabs' Tomislav Pericin said. Cybersecurity firm FireEye earlier this week  detailed  how multiple SolarWin...

Do you own an Android smartphone? You could be one of those 700 Million users whose phone is secretly sending text messages to China every 72 hours. You heard that right. Over 700 Million Android smartphones contain a secret 'backdoor' that surreptitiously sends all your text messages, call log, contact list, location history, and app data to China every 72 hours. Security researchers from Kryptowire discovered the alleged backdoor hidden in the firmware of many budget Android smartphones sold in the United States, which covertly gathers data on phone owners and sends it to a Chinese server without users knowing. First reported on by the New York Times on Tuesday, the backdoored firmware software is developed by China-based company Shanghai AdUps Technology, which claims that its software runs updates for more than 700 Million devices worldwide.

Kaspersky: NSA Worker's Computer Was Already Infected With Malware

Nov 17, 2017
Refuting allegations that its anti-virus product helped Russian spies steal classified files from an NSA employee's laptop, Kaspersky Lab has released more findings that suggest the computer in question may have been infected with malware. Moscow-based cyber security firm Kaspersky Lab on Thursday published the results of its own internal investigation claiming the NSA worker who took classified documents home had a personal home computer overwhelmed with malware. According to the latest Kaspersky report, the telemetry data its antivirus collected from the NSA staffer's home computer contained large amounts of malware files which acted as a backdoor to the PC. The report also provided more details about the malicious backdoor that infected the NSA worker's computer when he installed a pirated version of Microsoft Office 2013 .ISO containing the Mokes backdoor, also known as Smoke Loader.

China-backed Hackers Hijack Software Updates to Implant "NSPX30" Spyware

China-backed Hackers Hijack Software Updates to Implant "NSPX30" Spyware

Jan 25, 2024 Malware / Cyber Threat
A previously undocumented China-aligned threat actor has been linked to a set of adversary-in-the-middle (AitM) attacks that hijack update requests from legitimate software to deliver a sophisticated implant named NSPX30. Slovak cybersecurity firm ESET is tracking the advanced persistent threat (APT) group under the name  Blackwood . It's said to be active since at least 2018. The NSPX30 implant has been observed deployed via the update mechanisms of known software such as Tencent QQ, WPS Office, and Sogou Pinyin, with the attacks targeting Chinese and Japanese manufacturing, trading, and engineering companies as well as individuals located in China, Japan, and the U.K. "NSPX30 is a multistage implant that includes several components such as a dropper, an installer, loaders, an orchestrator, and a backdoor," security researcher Facundo Muñoz  said . "Both of the latter two have their own sets of plugins." "The implant was designed around the attackers...
US Agencies and FireEye Were Hacked Using SolarWinds Software Backdoor

US Agencies and FireEye Were Hacked Using SolarWinds Software Backdoor

Dec 14, 2020
State-sponsored actors allegedly working for Russia have  targeted  the US Treasury, the Commerce Department's National Telecommunications and Information Administration (NTIA), and other government agencies to  monitor internal email traffic  as part of a widespread cyberespionage campaign. The Washington Post, citing unnamed sources, said the latest attacks were the work of APT29 or Cozy Bear, the same hacking group that's believed to have orchestrated a breach of US-based cybersecurity firm  FireEye  a few days ago leading to the theft of its Red Team penetration testing tools. The motive and the full scope of what intelligence was compromised remains unclear, but signs are that adversaries tampered with a software update released by Texas-based IT infrastructure provider SolarWinds earlier this year to infiltrate the systems of government agencies as well as FireEye and mount a highly-sophisticated  supply chain attack . "The compromise of Sol...

Would Encryption Backdoor Stop Paris-like Terror Attacks?

Nov 17, 2015
With 129 people killed in Paris terror attacks and dozens critically wounded, the law enforcement and intelligence officials are reviving their efforts to force companies to put some backdoors in encryption so that they can access your information. How did the Intelligence agencies fail to Intercept terrorist plans of these attacks? In the wake of the Paris terror attacks, Former CIA Director Michael Morell argued on TV that encrypted communication services may have aided the planning and plotting of the Paris attacks, blaming Edward Snowden and US companies for the attacks. Also Read:  NO, We Can't Blame Edward Snowden and Encryption for Terror Attacks With more Surveillance and Encryption backdoor, Is it possible that Friday's attacks could have been stopped before they began? Morell suggested that recalcitrant US companies should be forced to install government backdoors in their software and hand over encryption keys to the government, thinking that Encryption Backd...
Software Supply-Chain Attack Hits Vietnam Government Certification Authority

Software Supply-Chain Attack Hits Vietnam Government Certification Authority

Dec 17, 2020
Cybersecurity researchers today disclosed a new supply-chain attack targeting the Vietnam Government Certification Authority (VGCA) that compromised the agency's digital signature toolkit to install a backdoor on victim systems. Uncovered by Slovak internet security company ESET early this month, the "SignSight" attack involved modifying software installers hosted on the CA's  website  ("ca.gov.vn") to insert a spyware tool called  PhantomNet  or Smanager. According to ESET's telemetry, the breach happened from at least July 23 to August 16, 2020, with the  two installers  in question — "gca01-client-v2-x32-8.3.msi" and "gca01-client-v2-x64-8.3.msi" for 32-bit and 64-bit Windows systems — tampered to include the backdoor. "The compromise of a certification authority website is a good opportunity for APT groups, since visitors are likely to have a high level of trust in a state organization responsible for digital signatures...
PlushDaemon APT Targets South Korean VPN Provider in Supply Chain Attack

PlushDaemon APT Targets South Korean VPN Provider in Supply Chain Attack

Jan 22, 2025 Supply Chain Attack / Malware
A previously undocumented China-aligned advanced persistent threat (APT) group named PlushDaemon has been linked to a supply chain attack targeting a South Korean virtual private network (VPN) provider in 2023, according to new findings from ESET. "The attackers replaced the legitimate installer with one that also deployed the group's signature implant that we have named SlowStepper – a feature-rich backdoor with a toolkit of more than 30 components," ESET researcher Facundo Muñoz said in a technical report shared with The Hacker News. PlushDaemon is assessed to be a China-nexus group that has been operational since at least 2019, targeting individuals and entities in China, Taiwan, Hong Kong, South Korea, the United States, and New Zealand. Central to its operations is a bespoke backdoor called SlowStepper, which is described as a large toolkit consisting of around 30 modules, programmed in C++, Python, and Go. Another crucial aspect of its attacks is the hijackin...
N.K. Hackers Employ Matryoshka Doll-Style Cascading Supply Chain Attack on 3CX

N.K. Hackers Employ Matryoshka Doll-Style Cascading Supply Chain Attack on 3CX

Apr 21, 2023 Supply Chain Attack
The supply chain attack targeting 3CX was the result of a prior supply chain compromise associated with a different company, demonstrating a new level of sophistication with North Korean threat actors. Google-owned Mandiant, which is  tracking  the attack event under the moniker  UNC4736 ,  said  the incident marks the first time it has seen a "software supply chain attack lead to another software supply chain attack." The Matryoshka doll-style cascading attack against 3CX first came to light on March 29, 2023, when it  emerged  that Windows and macOS versions of its communication software were trojanized to deliver a C/C++-based data miner named ICONIC Stealer by means of a downloader, SUDDENICON, that used icon files hosted on GitHub to extract the server containing the stealer. "The malicious application next attempts to steal sensitive information from the victim user's web browser," the U.S. Cybersecurity and Infrastructure Security Agency (CI...
Android Spyware Disguised as Alpine Quest App Targets Russian Military Devices

Android Spyware Disguised as Alpine Quest App Targets Russian Military Devices

Apr 23, 2025 Spyware / Mobile Security
Cybersecurity researchers have revealed that Russian military personnel are the target of a new malicious campaign that distributes Android spyware under the guise of the Alpine Quest mapping software. "The attackers hide this trojan inside modified Alpine Quest mapping software and distribute it in various ways, including through one of the Russian Android app catalogs," Doctor Web said in an analysis. The trojan has been found embedded in older versions of the software and propagated as a freely available variant of Alpine Quest Pro , a paid offering that removes advertising and analytics features. The Russian cybersecurity vendor said it also observed the malware, dubbed Android.Spy.1292.origin, being distributed in the form of an APK file via a fake Telegram channel. While the threat actors initially provided a link for downloading the app in one of the Russian app catalogs through the Telegram channel, the trojanized version was later distributed directly as an A...
A Second Hacker Group May Have Also Breached SolarWinds, Microsoft Says

A Second Hacker Group May Have Also Breached SolarWinds, Microsoft Says

Dec 22, 2020
As the probe into the  SolarWinds supply chain attack  continues, new digital forensic evidence has brought to light that a separate threat actor may have been abusing the IT infrastructure provider's Orion software to drop a similar persistent backdoor on target systems. "The investigation of the whole SolarWinds compromise led to the discovery of an additional malware that also affects the SolarWinds Orion product but has been determined to be likely unrelated to this compromise and used by a different threat actor," Microsoft 365 research team  said  on Friday in a post detailing the Sunburst malware. What makes the newly revealed malware, dubbed "Supernova," different is that unlike the Sunburst DLL,  Supernova  ("app_web_logoimagehandler.ashx.b6031896.dll") is not signed with a legitimate SolarWinds digital certificate, signaling that the compromise may be unrelated to the previously disclosed supply chain attack. In a  standalone write-up , ...
