Someone Hacked 50,000 Printers to Promote PewDiePie YouTube Channel

Someone Hacked 50,000 Printers to Promote PewDiePie YouTube Channel
December 01, 2018Mohit Kumar
This may sound crazy, but it's true! The war for "most-subscribed Youtube channel" crown between T-Series and PewDiePie just took an interesting turn after a hacker yesterday hijacked more than 50,000 internet-connected printers worldwide to print out flyers asking everyone to subscribe to PewDiePie YouTube channel. PewDiePie, whose real name is Felix Kjellberg, is a famous YouTuber from Sweden known for his game commentary and pranks and has had the most subscribers on YouTube since 2013. However, the channel owned by Bollywood record label T-Series has been catching up in recent months, and now both are hovering around 72.5 million YouTube subscribers. From this fear that PewDiePie won't remain the number one most-subscribed YouTuber in the world, an anonymous hacker (probably his die-hard fan) with the Twitter username " TheHackerGiraffe " came up with a hackish idea. TheHackerGiraffe scanned the Internet to find the list of vulnerable printers

Hackers can compromise your network just by sending a Fax

Hackers can compromise your network just by sending a Fax
August 14, 2018Swati Khandelwal
What maximum a remote attacker can do just by having your Fax machine number? Believe it or not, but your fax number is literally enough for a hacker to gain complete control over the printer and possibly infiltrate the rest of the network connected to it. Check Point researchers have revealed details of two critical remote code execution (RCE) vulnerabilities they discovered in the communication protocols used in tens of millions of fax machines globally. You might be thinking who uses Fax these days! Well, Fax is not a thing of the past. With more than 300 million fax numbers and 45 million fax machines in use globally, Fax is still popular among several business organizations, regulators, lawyers, bankers, and real estate firms. Since most fax machines are today integrated into all-in-one printers, connected to a WiFi network and PSTN phone line, a remote attacker can simply send a specially-crafted image file via fax to exploit the reported vulnerabilities and seize co

Remotely Exploitable Flaw Found In HP Enterprise Printers—Patch Now

Remotely Exploitable Flaw Found In HP Enterprise Printers—Patch Now
November 23, 2017Mohit Kumar
Security researchers have discovered a potentially dangerous vulnerability in the firmware of various Hewlett Packard (HP) enterprise printer models that could be abused by attackers to run arbitrary code on affected printer models remotely. The vulnerability (CVE-2017-2750), rated as high in severity with 8.1 CVSS scale, is due to insufficiently validating parts of Dynamic Link Libraries (DLL) that allows for the potential execution of arbitrary code remotely on affected 54 printer models. The security flaw affects 54 printer models ranging from HP LaserJet Enterprise, LaserJet Managed, PageWide Enterprise and OfficeJet Enterprise printers. This remote code execution (RCE) vulnerability was discovered by researchers at FoxGlove Security when they were analyzing the security of HP's MFP-586 printer (currently sold for $2,000) and HP LaserJet Enterprise M553 printers (sold for $500). According to a technical write-up posted by FoxGlove on Monday, researchers were able to

FBI Arrests NSA Contractor for Leaking Secrets – Here's How they Caught Her

FBI Arrests NSA Contractor for Leaking Secrets – Here's How they Caught Her
June 06, 2017Mohit Kumar
The FBI arrested a 25-year-old NSA contractor on Saturday (3rd June) for leaking classified information to an online news outlet which published its report yesterday (5th June) — meaning the arrest was made two days before the actual disclosure went online. Reality Leigh Winner , who held a top-secret security clearance and worked as a government contractor in Georgia with Pluribus International, was arrested from her home in Augusta on charges involving the leak of top-secret NSA files to 'The Intercept,' an online publication that has been publishing NSA documents leaked by Edward Snowden since 2014. The Intercept published a report on Monday, 5th June, based upon a classified document it received anonymously, which claims in August 2016, Russia's military intelligence agency "executed a cyber attack on at least one U.S. voting software supplier and sent spear-phishing emails to more than 100 local election officials days before [the] election."

Imagine you are sitting in your office and working on something confidential. Once you are done, you send a command to print that document. But, What if...  ...the whole confidential document send to a hacker attacking from the air? Sounds pity but may be your Boss fires you immediately if that confidential data is leaked or misused. This is no more an imagination now, as a group of researchers has done exactly the same. Researchers from Singapore have devised a unique set up consisting of a Drone that carries a smartphone running two custom apps that are capable of intercepting wireless printer transmissions, even from outside an office building. In short, hackers can gain access to your corporate network by using a smartphone-equipped drone to hack your printer. The project was developed by the researchers at iTrust , a research center at the Singapore University of Technology and Design. They developed two applications: Cybersecurity Patrol – To d

This Antenna Can Remotely Steal Data From Devices using Sound Waves

This Antenna Can Remotely Steal Data From Devices using Sound Waves
August 06, 2015Swati Khandelwal
Remember the previously demonstrated technique to Hack into air-gapped computers using Heat waves? What if the same was possible to hack computers to steal data using Sound waves ? Imagine, If a remote hacker could steal classified information from a targeted computer without having to physically and Internet access to it. A team of security researchers has demonstrated exactly the same by developing a new hacking technique called Funtenna that uses sound and radio waves to siphon data from computers even without Internet access. According to a lead researcher Ang Cui of Red Balloon Security, the Funtenna radio signal hack has the potential to turn Internet-connected devices (printer, washing machine and air conditioner) – popularly known as the Internet of Things – into bugs that can transmit data out of a network using sound waves that can not be heard by a human ear. How Funtenna Works? The attacker only needs to install malware on a target's devic

Do you own an HP printer? If so, it may be vulnerable to Hackers. Multiple HP LaserJet Pro Printers are printer vulnerable to hackers according to a new advisory posted by the vendor, dubbed as  CVE-2013-4807  (SSRT101181). Researcher ' Micha Sajdak ' of Securitum.pl have found a security hole HP LaserJet printers that allows a remote hacker to extract the admin password in plain text, among other information like WiFi settings including the WPS PIN . The main issue is with some of the networked HP LaserJet printers, having hidden URLs hardcoded in the firmware, which can be accessed without authentication. The vulnerability could be exploited remotely to gain unauthorized access to data. For example : https://IP_ADDRESS/dev/save_restore.xml Where the password seems to be encrypted, but the value contains a hex representation of the admin password in plain text, i.e. 0x746573746f7765 = testowe. Also, If a printer is WiFi enabled, then the WiFi info c

He said the vulnerability could also be used for a denial-of-service attack. " As long as the printer is not connected to the Internet, this vulnerability should not cause much trouble for the end user ,". Marked as CVE-2012-5215 ( VU#782451 , SSRT101078), vulnerability affected 12 printer models including HP LaserJet Pro P1102w, P1102w, P1606dn, M1212nf MFP, M1213nf MFP, M1214nfh MFP, M1216nfh Multifunction Printer, M1217n

Samsung printer having secret admin account Backdoor

Samsung printer having secret admin account Backdoor
November 28, 2012Mohit Kumar
US CERT warn about Some Samsung printers, including models the Korean company made for Dell, have a backdoor administrator account coded into their firmware. This hard coded admin account in firmware could enable attackers to change their configuration, read their network information or stored credentials and access sensitive information passed to them by users. Screenshot Even if SNMP is disabled, this " backdoor administrator account " is still active and could be used by an attacker to access the printer. SNMP is an Internet protocol commonly used to monitor and read statistics from network-attached devices. US-CERT did not provide a list with the exact printer models affected by the issue, but said that, according to Samsung, models released after Oct. 31, 2012, are not vulnerable. As for the Dell model, Samsung builds Dell printers such as the B1160w modeled after Samsung's ML-2165W compact all-in-one printer. It's unclear what other Dell b
