Exfiltrating Data from Air-Gapped Computers Using Screen Brightness

Exfiltrating Data from Air-Gapped Computers Using Screen Brightness

Feb 05, 2020
It may sound creepy and unreal, but hackers can also exfiltrate sensitive data from your computer by simply changing the brightness of the screen, new cybersecurity research shared with The Hacker News revealed. In recent years, several cybersecurity researchers demonstrated innovative ways to covertly exfiltrate data from a physically isolated air-gapped computer that can't connect wirelessly or physically with other computers or network devices. These clever ideas rely on exploiting little-noticed emissions of a computer's components, such as light, sound , heat , radio frequencies , or ultrasonic waves , and even using the current fluctuations in the power lines. For instance, potential attackers could sabotage supply chains to infect an air-gapped computer, but they can't always count on an insider to unknowingly carry a USB with the data back out of a targeted facility. When it comes to high-value targets, these unusual techniques, which may sound theoretica...

'iTunes Wi-Fi Sync' Feature Could Let Attackers Hijack Your iPhone, iPad Remotely

'iTunes Wi-Fi Sync' Feature Could Let Attackers Hijack Your iPhone, iPad Remotely

Apr 19, 2018
Be careful while plugging your iPhone into a friend's laptop for a quick charge or sharing selected files. Researchers at Symantec have issued a security warning for iPhone and iPad users about a new attack, which they named " TrustJacking ," that could allow someone you trust to remotely take persistent control of, and extract data from your Apple device. Apple provides an iTunes Wi-Fi sync feature in iOS that allows users to sync their iPhones to a computer wirelessly. To enable this feature, users have to grant one-time permission to a trusted computer (with iTunes) over a USB cable. Once enabled, the feature allows the computer owner to secretly spy on your iPhone over the Wi-Fi network without requiring any authentication, even when your phone is no longer physically connected to that computer. "Reading the text, the user is led to believe that this is only relevant while the device is physically connected to the computer, so assumes that disconnecti...
APT Hackers Infect Routers to Covertly Implant Slingshot Spying Malware

APT Hackers Infect Routers to Covertly Implant Slingshot Spying Malware

Mar 09, 2018
Security researchers at Kaspersky have identified a sophisticated APT hacking group that has been operating since at least 2012 without being noticed due to their complex and clever hacking techniques. The hacking group used a piece of advanced malware—dubbed Slingshot —to infect hundreds of thousands of victims in the Middle East and Africa by hacking into their routers. According to a 25-page report published [ PDF ] by Kaspersky Labs, the group exploited unknown vulnerabilities in routers from a Latvian network hardware provider Mikrotik as its first-stage infection vector in order to covertly plant its spyware into victims' computers. Although it is unclear how the group managed to compromise the routers at the first place, Kaspersky pointed towards WikiLeaks Vault 7 CIA Leaks , which revealed the ChimayRed exploit , now available on GitHub , to compromise Mikrotik routers. Once the router is compromised, the attackers replace one of its DDL (dynamic link libraries) ...
Here's How CIA Spies On Its Intelligence Liaison Partners Around the World

Here's How CIA Spies On Its Intelligence Liaison Partners Around the World

Aug 24, 2017
WikiLeaks has just published another Vault 7 leak, revealing how the CIA spies on their intelligence partners around the world, including FBI, DHS and the NSA, to covertly collect data from their systems. The CIA offers a biometric collection system—with predefined hardware, operating system, and software—to its intelligence liaison partners around the world that helps them voluntary share collected biometric data on their systems with each other. But since no agency share all of its collected biometric data with others, the Office of Technical Services (OTS) within CIA developed a tool to secretly exfiltrate data collections from their systems. Dubbed ExpressLane , the newly revealed CIA project details about the spying software that the CIA agents manually installs as part of a routine upgrade to the Biometric system. The leaked CIA documents reveal that the OTS officers, who maintain biometric collection systems installed at liaison services, visit their premises and se...
Beware! Subtitle Files Can Hack Your Computer While You're Enjoying Movies

Beware! Subtitle Files Can Hack Your Computer While You're Enjoying Movies

May 23, 2017
Do you watch movies with subtitles? Just last night, I wanted to watch a French movie, so I searched for English subtitles and downloaded it to my computer. Though that film was excellent, this morning a new research from Checkpoint scared me. I was unaware that a little subtitle file could hand over full control of my computer to hackers, while I was enjoying the movie. Yes, you heard that right. A team of researchers at Check Point has discovered vulnerabilities in four of the most popular media player applications, which can be exploited by hackers to hijack " any type of device via vulnerabilities; whether it is a PC, a smart TV, or a mobile device " with malicious codes inserted into the subtitle files. " We have now discovered malicious subtitles could be created and delivered to millions of devices automatically, bypassing security software and giving the attacker full control of the infected device and the data it holds, " he added. These ...
Iranian Ajax Security Team targets US Defense Industry

Iranian Ajax Security Team targets US Defense Industry

May 14, 2014
The Iranian hacking group, which calls itself the " Ajax Security Team ", was quite famous from last few years for websites defacement attacks , and then suddenly they went into dark since past few months. But that doesn't mean that the group was inactive, rather defacing the websites, the group was planning something bigger. The Group of hackers at Ajax Security Team last defaced a website in December 2013 and after that it transitioned to sophisticated malware-based espionage campaigns in order to target U.S. defense organizations and Iranian dissidents, according to the report released by FireEye researchers. " The transition from patriotic hacking to cyber espionage is not an uncommon phenomenon. It typically follows an increasing politicization within the hacking community, particularly around geopolitical events ," researchers Nart Villeneuve, Ned Moran, Thoufique Haq and Mike Scott wrote in the report. " This is followed by increasing links between the hacking ...
WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

Apr 01, 2020
Cybersecurity researchers today uncovered a sustained malicious campaign dating back to May 2018 that targets Windows machines running MS-SQL servers to deploy backdoors and other kinds of malware, including multi-functional remote access tools (RATs) and cryptominers. Named " Vollgar " after the Vollar cryptocurrency it mines and its offensive "vulgar" modus operandi, researchers at Guardicore Labs said the attack employs password brute-force to breach Microsoft SQL servers with weak credentials exposed to the Internet. Researchers claim the attackers managed to successfully infect nearly 2,000-3,000 database servers daily over the past few weeks, with potential victims belonging to healthcare, aviation, IT & telecommunications, and higher education sectors across China, India, the US, South Korea, and Turkey. Thankfully for those concerned, researchers have also released a script to let sysadmins detect if any of their Windows MS-SQL servers have been...
