Universal Man in the Browser Attacks

Oct 03, 2012
Researchers have discovered a new type of Man-in-the-Browser (MItB) attack that is Website independent, and does not target specific Websites, but instead collects data submitted to all sites. Trusteer have discovered a new Man in the Browser (MitB) scam that can collects data submitted to all websites without the need for post-processing. According to Trusteer's CTO Amit Klein: " In comparison, uMitB does not target a specific web site. Instead, it collects data entered in the browser at all websites and uses "generic" real time logic on the form submissions to perform the equivalent of post-processing. This attack can target victims of new infections as well as machines that were previously infected by updating the existing malware with a new configuration. The data stolen by uMitB malware is stored in a portal where it is organized and sold ." In a YouTube video, the company demonstrated how the attack could happen. The video showed how a user could enter personal a

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

300% Increase in malnets Attack in the past six months

Oct 03, 2012
Blue Coat systems has undertaken detailed research into the use of 'malnets' by criminals to help support their various attacks in order to uncover the best ways to take down these systems. Botnet infections are commonly spread though compromised websites seeded with malicious scripts and promoted via black hat SEO tactics such as link farms. These malware networks, or malnets, pose a growing threat, The company said the number of malnets now stands at more than 1,500, an increase of 300% in the past six months, and it expects they will be, "responsible for two-thirds of all malicious cyberattacks in 2012." According to Blue Coat, the largest known malnet is Shnakule, which has used up to 5,005 malicious hosts or servers at any given time, depending on the capabilities needed at any given moment by its operators. Blue Coat believes that Shnakule is controlled by a single gang, and it's been used to serve up just about every type of known attack, including &quo

Millions of DSL modems hacked in Brazil, spread banking malware

Oct 02, 2012
More than 4.5 million DSL modems have been compromised as part of a sustained hacking campaign in Brazil, with the devices spreading malware and malicious web address redirects. According to the malware analyst at Kaspersky Lab in Brazil, Fabio Assolini. The vulnerability exploited by attackers allowed the use of a script to steal passwords and remotely access the configuration of modems. The attacks was described as " One firmware vulnerability, two malicious scripts, three hardware manufacturers, 35 malicious DNS servers, thousands of compromised ADSL modems, millions of victims. " According to Kaspersky, the Brazilian attackers sought to steal users' banking credentials by redirecting users to false versions of popular sites like Facebook or Google and prompting them to install malware. Some 40 DNS servers were set up outside Brazil too in order to serve forged requests for domain names belonging to Brazilian banks. Nakedsecurity writes,-- The first thing users ma

ARMY : USB Drive responsible for over 70 percent of Cyber Security Breaches

Sep 30, 2012
A ban on the use of pen drives has not been able to safeguard cyber security as it has now been labeled as a major threat in defence forces, the Army officials said. The use of pen drives as an easy-to-carry storage device has increased in the recent past and internal reports have confirmed that over 70 percent cyber security breaches in the armed forces are due to their unauthorised use " These pen drives, which are mostly manufactured in China, have emerged as a big threat to our cyber security systems ," they said. Generally it is found that officials use pen drive to store official data for use at their personal computers but from there, it is transmitted from their IP addresses to hackers from the 'malware' present in the pen drives. About a couple of years ago, a Major posted in Andaman and Nicobar Islands was apprehended as it was found that sensitive data was being transferred from his computer.  However, it later emerged that his system had been hacked and

It's a fact that as smartphones get more capable, the possibilities for their misuse also increase. They're already exploited by crooks to swipe personal information, but a new Android app created by the U.S. Navy is on another level entirely. It's a scary piece of malware called " PlaceRaider " that was developed by the US Naval Surface Warfare center and for now it is being viewed as just a proof of concept. According to the MIT Technology Review, researchers at Indiana University and the Naval Surface Warfare Center have developed a new form of malware designed to record and reconstruct a victim's environment. They has just worked out how to infect a mobile phone with a Trojan that can take photos without you knowing anything about it and send sensor data back to a server. The data are used to construct a 3D model which can be used not only to perform the reconnaissance necessary to break in, but also to steal confidential information such as bank details. O
New Android Exploit Could Force Factory Reset remotely

New Android Exploit Could Force Factory Reset remotely

Sep 25, 2012
Clicking one wrong link can cause malicious code to execute, which could do anything from infecting your computer with malware to, apparently, wiping your phone data completely. At the Ekoparty security conference, researcher Ravi Borganokar demonstrated at the Ekoparty security conference in Argentina last week, that how a single line of HTML code could be used to run a factory reset or even clear the SIM card on certain Samsung phones. Malicious hackers can hide a code in a web page that will trigger a full factory reset of Samsung's best-selling Galaxy S3 smartphone, deleting contacts, photographs, music, apps and other valuable data. The devastating flaw lies in Samsung's dialling software, triggered by the tel protocol in a URL. It isn't applicable to all the company's Android handsets, but those that are vulnerable can have their PIN changed or be wiped completely just by visiting a web page or snapping a bad QR code, or even bonking up against the wrong wireless N

Exploit Released for Internet Explorer zero-day attacks : CVE-2012-4969

Sep 19, 2012
Microsoft has confirmed reports that a zero-day vulnerability in its Internet Explorer browser is being actively attacked in the wild. Four active exploits of a zero-day vulnerability in the browser exists. Microsoft will push out an out-of-cycle Windows patch to temporarily fix the critical Internet Explorer flaw. Security researcher Eric Romang identified the exploit code on a server used by the "Nitro" hacking group, believed to have exploited the Java zero-day vulnerability reported last month.  Security firm Rapid7 advises that Internet users try a different Web browser. The malware may be linked to an ongoing attack on companies that has been dubbed "Nitro", and was first discovered in October by Symantec. The zero-day in IE 6-9 is a use-after-free memory corruption vulnerability , similar to a buffer overflow, that would enable an attacker to remotely execute code on a compromised machine. The original exploit payload dropped the PoisonIvy remote access Trojan (RAT)

Android 4.0.4 multiple Zero-Day Vulnerabilities

Sep 19, 2012
The Samsung Galaxy S3 can be hacked via NFC, allowing attackers to download all data from the Android smartphone, security researchers demonstrated during the Mobile Pwn2Own contest in Amsterdam. Using a pair of zero day vulnerabilities, a team of security researchers from U.K.-based MWR Labs hacked into a Samsung Galaxy S3 phone running Android 4.0.4 by beaming an exploit via NFC (Near Field Communications). NFC is a technology that allows data to be sent over very short distances. For mobile devices, the protocol allows digital wallet applications to transfer money to pay at the register. While the technology has been slow to take off, despite the adoption by Google for its Wallet payment application, a number of recent high-profile announcements have boosted its adoption. " Through NFC it was possible to upload a malicious file to the device, which allowed us to gain code execution on the device and subsequently get full control over the device using a second vulnerability

Sep 08, 2012
A new Ransomware Malware dubbed Gaeilge  locks up an infected computer and attempts to extort €100 from the user for an unlock code. The demand for cash reportedly appeared in poorly written Gaelic, and the software nastie was spotted on a computer in County Donegal, Ireland. Gaeilge tell computer users that attempts to access online pornography sent it into shut-down mode. But instead of giving in to the monetary request, the victim took the compromised machine to the repair store, The Register said . Ransomware  (also referred to in some cases as cryptoviruses, cryptotrojans or cryptoworms) comprises a class of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator of the malware in order for the restriction to be removed. Technician Brian McGarvey of Techie2u computer repairs told that it was the first time he'd come across a virus written in the Irish language during his 12 years of experience in the job. " It'

Sep 03, 2012
The Metropolitan Police have issued an urgent warning about a new ransom malware that is in circulation. Ransomware (also referred to in some cases as cryptoviruses, cryptotrojans or cryptoworms) comprises a class of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator of the malware in order for the restriction to be removed. " The "malware" infects personal computers after users have accessed certain websites. *(It should be noted that there are several similar designs currently in circulation) " Ransomware typically propagates like a typical computer worm, entering a system through, for example, a downloaded file or a vulnerability in a network service. The program will then run a payload which will begin to encrypt personal files on the hard drive. More sophisticated ransomware may hybrid-encrypt the victim's plaintext with a random symmetric key and a fixed public key. The malware author is th

Wiper, the Destructive Malware possibly connected to Stuxnet and Duqu

Sep 01, 2012
Kaspersky Lab publishes research resulting from the digital forensic analysis of the hard disk images obtained from the machines attacked by the Wiper - a destructive malware program attacking computer systems related to oil facilities in Western Asia. Security researchers from Kaspersky Lab have uncovered information suggesting a possible link between the mysterious malware that attacked Iranian oil ministry computers in April and the Stuxnet and Duqu cyber espionage threats. The malware wipes data from hard drives, placing high priority on those with a .pnf extension, which are the type of files Stuxnet and Duqu used, and has other behavioral similarities, according to Schouwenberg. It also deletes all traces of itself. As a result, researchers have not been able to get a sample, but they've reviewed mirror images left on hard drives. Kaspersky's researchers were not able to find the mysterious malware, which was given the name Wiper, because very little data from the aff
