Another WordPress Vulnerability Discovered, Millions of Websites at Risk

A security researcher from Web security firm Sucuri recently discovered a cross-site scripting (XSS) vulnerability present in every default installation of WordPress, a popular content management system (CMS) used by millions of websites around the world. The vulnerability, which is part of the default WordPress Twenty Fifteen theme, is a DOM-based (Document Object Model) flaw. DOM is responsible for the rendering of images, text, links, and headers within a Web browser. The vulnerability is the result of an insecure file within the 'Genericons' package that allows the DOM environment of the victim's browser to be modified by hackers.

New Malware Destroys Hard Drive to Avoid Detection

Security researchers recently discovered a new strain of malware that uses unique – and somewhat extraordinary – measures to avoid detection and analysis. Known as Rombertik, this malware strain is unique even among other forms of self-destructing malware due to its unusual evasion techniques. Once Rombertik detects any analysis tool on the infected machine, it immediately attempts to delete the PCs Master Boot Record (MBR) and all home directories. This puts the machine in a constant reboot loop – essentially making the computer unusable. This complex piece of malware collects data about everything a user does online in an attempt to obtain login credentials and other sensitive information.

Russian Government behind Long-Term Cyberespionage Campaign?

In a report issued by security firm FireEye last October, a group of hackers known as APT28 has been secretly targeting government organizations around the world in an attempt to gather as yet unknown information in a campaign with its roots in Russia. Specifically, FireEye was able to determine that APT28 has an apparent government sponsor located in Moscow. Unlike many of the China-based threats that have made recent headlines, the hackers of APT28 do not appear to be seeking financial gain from the intellectual property stolen during a breach.

Yet Another POS Malware Strain Discovered

Last week, this blog reported on a dangerous strain of malware, known as PoSeidon that is targeting the POS systems of small retailers including bars and restaurants. A recent report issued by security firm Trustwave indicates that yet another malware variant specifically targeting POS systems has been spotted in the wild. This malware, known as Punkey, appears to have evolved from the recently discovered “NewPOSthings” family of malware first discovered by researchers from Arbor Networks. While the discovery of Punkey is the topic of this article, it’s worth pointing out that TrendMicro recently detailed the discovery of multiple malware strains based on the NewPOSthings source code.

POS Providers Targeted by PoSeidon Malware

Researchers recently discovered a new strain of malware, known as PoSeidon, designed to steal credit and debit card information from compromised POS devices. PoSeidon has already been implicated in numerous breaches targeting numerous businesses including restaurants, bars, and hotels. Unlike previous POS-targeted attacks that focused on larger companies like Target and Home Depot, cybercriminals have decided to start focusing on smaller retailers. Targeting these smaller POS users has made it especially difficult for financial institutions to track credit card fraud and represents nothing more than the latest iteration in a constantly evolving cat-and-mouse game between cybercriminals and financial institutions around the world.

ISIS Targeting WordPress-powered Websites

The FBI recently released a warning to all WordPress users detailing a plot by terrorist organization ISIS to exploit vulnerable sites to display pro-ISIS messages. According to the FBI report, ISIS and its many sympathizers around the world are targeting WordPress sites – especially those operated by commercial entities, news organizations, religious institutions, and all levels of government (both foreign and domestic). So far, it appears that the individuals behind these attacks are not professional hackers. In other words, these are unskilled computer users that are leveraging known WordPress plugin flaws in readily-available hacking tools.

FREAK Encryption Flaw a Remnant from the 1990s, Affects All Browsers

High level security researchers recently discovered a vulnerability in all supported versions of Microsoft Windows that affects the security afforded by industry-standard encryption protocols. This flaw, which has been dubbed “FREAK” (Factoring RSA Export Keys), was originally thought to only affect Apple’s Safari and Google’s Android browsers, but has now been found to affect all versions of Microsoft Windows as well. Specifically, Secure Sockets Layer (SSL) and its successor, Transport Layer Security (TLS), are the encryption protocols within Windows that are vulnerable to FREAK.

Improved Vawtrak Trojan Spotted in the Wild

Last year this blog reported on a dangerous banking Trojan known as Vawtrak. Originally discovered by researchers at Trend Micro, Vawtrak works by targeting a feature of Windows known as Software Restriction Policies (SRP). Essentially, SRP prevents infected systems from running programs specified by the creators of malware. In the case of Vawtrak, blocked programs include over 53 antivirus and security programs including products from Trend Micro, AVG, ESET, Symantec, Intel, and Microsoft. The idea is simple: by disarming local security features found on most PCs, Vawtrak is able to perform its primary task – stealing online banking credentials – without so much as a peep from the operating system.

Superfish May Be Just the Tip of the Iceberg for Adware Privacy Concerns

Last week this blog reported a story about Lenovo, one of the world’s largest manufacturers of PCs and tablets, and how the company has been installing adware on its products at the factory. This adware, dubbed Superfish, is designed to intercept encrypted Web connections relying on SSL technology. Unfortunately, a flaw in the program design allows hackers to intercept these transmissions in the form of a man-in-the-middle attack – potentially putting the secure personal information of millions of PC users at risk. Discovery of Superfish has already landed Lenovo in hot water.

Hackers Steal Over $300 Million from Banks in Elaborate Heist

According to Russian cybersecurity company Kaspersky Labs, the banking industry has just been catapulted into “a new era in cybercrime.” This statement comes after Kaspersky concluded an 18 month long investigation into a sophisticated cyberattack that has been targeting financial institutions worldwide since 2013. Although the actual amount of money stolen via this complex attack varies between $300 million and $1 billion depending on the source, what is clear is that the group responsible for this attack represents one of the most complex cyberattacks ever discovered. Kaspersky was first invited to investigate the matter after a Ukrainian ATM began spitting out cash at random without anyone inserting a card or touching any buttons on the machine.

Lenovo Shipping PCs with Adware Pre-Installed

Lenovo has become one of the most popular PC manufacturers in recent years due mostly to competitive pricing and an assortment of products catering to every customer need. Unfortunately, security experts have recently uncovered that Lenovo is also shipping these popular computers with invasive marketing software that borders on malware. This malware could easily open up doors for cybercriminals and hackers – let alone the fact that Lenovo doesn’t seem to have a problem spying on its very own customers to make a few extra bucks. This software, known as Superfish Malware, is designed to analyze users’ Internet habits and inject third-party advertising in popular web browsers including Google Chrome and Internet Explorer with the PC user’s permission. Superfish Malware has been on all new consumer-grade Lenovo laptops sold prior to January 2015. The malware is immediately activated when the machine is turned on for first-use and Lenovo customers are using the malware without knowing the dangers inherent to malware like Superfish.
