A Lab42 survey, which polled consumers across the United States, Germany, France, New Zealand, Australia and the United Kingdom, highlights the psychology around why consumers develop poor password habits despite understanding the obvious risk, and suggests that there is a level of cognitive dissonance around our online habits.
Pierre Kim said attackers could easily exploit the vulnerabilities and use the device as a spamming zombie or a man-in-the-middle tool. The mules usually are then asked to withdraw the funds in cash and wire the money to the scammers. Increasingly, however, the mules are being instructed to remit the stolen money via Bitcoin ATMs. Based on newly released findings from the Breach Level Index BLI , there were publicly disclosed data breaches in the first half of , which led to the successful theft or loss of million data records.
Cross-site scripting XSS is a common security issue web developers face today. The attack, which relies on vulnerabilities which allow the injection of malicious codes into trusted websites and applications, can lead to malvertising campaigns, watering hole attacks, and drive-by attacks which do not need victims, visiting a trusted site, to do anything more than open a page. CSP, support by all major browsers, can be used to restrict programming input and scripts and prevent them executing, even if attackers are able to inject malicious code into vulnerable web pages.
Now, there's word of a similar attack on a French Web host that peaked at a staggering 1. The first one reached 1. Then, last Friday, he reported more attacks that were in the same almost incomprehensible range. He said the distributed denial-of-service DDoS attacks were delivered through a collection of hacked Internet-connected cameras and digital video recorders.
With each one having the ability to bombard targets with 1 Mbps to 30 Mbps, he estimated the botnet had a capacity of 1. On Monday, Klaba reported that more than 6, new cameras had joined the botnet and said further that over the previous 48 hours the hosting service was subjected to dozens of attacks, some ranging from Gbps to Gbps. On Wednesday, he said more than 15, new devices had participated in attacks over the past 48 hours.
Experts had previously said that the rollout of smart wallet systems could raise such a threat. However, the police are unsure exactly how the attacks are being carried out and how common they are.
Lockscreen ransomware now using pseudorandom numbers New variants of Android. Lockscreen are using pseudorandom passcodes to prevent victims from unlocking devices without paying the ransom. Previous versions of these threats locked the screen and used a hardcoded passcode, but analysts were able to reverse engineer the code to provide victims with the passcode to unlock their devices.
Attackers have also combined a custom lockscreen with the device's lockscreen to create an additional hurdle for those infected. Similar to some other mobile threats we've observed, these Trojans are being created directly on mobile devices before being distributed. Symantec detects these threats as Android. The Virlock variant is yet another instance of cybercriminals deploying new techniques in order to make ransomware even more effective: Virlock has been active for almost two years now, and security researchers at Netskope have discovered how Virlock can employ a 'fan-out' effect, spreading itself through the use of cloud sync, cloud storage, and collaboration applications.
Do people know about them? Are they being targeted? Take a look at this global problem with the Kaspersky Index. The browser-trusted WoSign authority intentionally back-dated certificates it has issued over the past nine months to avoid an industry-mandated ban on the use of the SHA-1 hashing algorithm, Mozilla officials charged in a report published Monday.
SHAbased signatures were barred at the beginning of the year because of industry consensus they are unacceptably susceptible to cryptographic collision attacks that can create counterfeit credentials.
To satisfy customers who experienced difficulty retiring the old hashing function, WoSign continued to use it anyway and concealed the use by dating certificates prior to the first of this year, Mozilla officials said.
They also accused WoSign of improperly concealing its acquisition of Israeli certificate authority StartCom, which was used to issue at least one of the improperly issued certificates. The only thing being exploited here is the user. If a database containing plain-text passwords is compromised, user accounts are in immediate danger.
For this reason, as early as , the industry standardized on storing passwords using secure, one-way hashing mechanisms starting with Unix Crypt. Unfortunately, while this prevents the direct reading of passwords in case of a compromise, all hashing mechanisms necessarily allow attackers to brute force the hash offline, by going through lists of possible passwords, hashing them, and comparing the result.
In this context, secure hashing functions like SHA have a critical flaw for password hashing: Specialized GPU clusters allow for calculating hashes at a rate of billions per second. In this post, we want to share more details of our current password storage mechanism and our reasoning behind it. Our password storage scheme relies on three different layers of cryptographic protections, as the figure below illustrates.
For ease of elucidation, in the figure and below we omit any mention of binary encoding base Earlier this week, the open-source website content management system CMS released a security advisory detailing the latest security issues which have been both discovered and fixed. The first bug, considered the least dangerous of the three, is a problem which allows users without admin rights to set comment visibility on nodes they have rights to edit.
By default, these user accounts should not be able to made these changes. We recently noted the non-linear growth of ransomware variants and now a new type has emerged, dubbed MarsJoke. Proofpoint researchers originally spotted the MarsJoke ransomware in late August [1] by trawling through our repository of unknown malware. However, beginning on September 22, , we detected the first large-scale email campaign distributing MarsJoke.
This ongoing campaign appears to target primarily state and local government agencies and educational institutions in the United States. The targeting of state and local government agencies as well as the distribution methods are very similar to a CryptFile2 campaign we described in August [2].
The patch was the most severe of 14 released yesterday by OpenSSL. OCSP is an alternative in many cases to Certificate Revocation Lists where a client can use the protocol to ping a server requesting the status of a digital certificate. The study, published in the Journal of Cybersecurity, challenges the much higher cost estimates provided by the Ponemon Institute. This figure is on a par with the 0. Spam at levels not seen since Spam is back in a big way — levels that have not been seen since o in fact.
To help keep the full scope of the botnet hidden, Necurs will only send spam from a subset of its minions. An infected host might be used for two to three days, and then sometimes not again for two to three weeks. This greatly complicates the job of security personnel who respond to spam attacks, because while they may believe the offending host was subsequently found and cleaned up, the reality is that the miscreants behind Necurs are just biding their time, and suddenly the spam starts all over again.
The goal of this project is to identify the vulnerable systems and report them back to the network owners for remediation. Because email is the top entry point used by prevalent ransomware families. Over the first half of the year, we observed how cybercriminals leveraged file types like JavaScript, VBScript, and Office files with macros to evade traditional security solutions. Some of these file types can be used to code malware. In fact, as a security precaution, Microsoft turns off macros by default.
In this blog post, we examine various email file attachments and how ransomware affected the fluctuation in the use of these file types. The criminals are of course hoping that the unsuspecting recipients will plug the freebie USB drives into their computers. Though apparent language clarity and friendliness could lull the vigilance of software engineers and system administrators -- luring them into coding mistakes that may have serious security implications.
In this article, which primarily targets people who are new to Python, a handful of security-related quirks are looked at; experienced developers may well be aware of the peculiarities that follow. The flaw allows hackers to remotely extract the contents of a device's memory, which can lead to the exposure of sensitive information. This key exchange protocol is used for VPNs Virtual Private Networks and other features that are popular in enterprise environments. As a result, the cross-platform, malicious code-execution risk most recently visited users of browsers based on the Firefox Extended Release on September 3 and lasted until Tuesday, or a total of 17 days.
The same Firefox version was vulnerable for an even longer window last year, starting on July 4 and lasting until August The bug was scheduled to reappear for a few days in November and for five weeks in December and January. Both the Tor Browser and the production version of Firefox were vulnerable during similarly irregular windows of time.
While the windows were open, the browsers failed to enforce a security measure known as certificate pinning when automatically installing NoScript and certain other browser extensions. That meant an attacker who had a man-in-the-middle position and a forged certificate impersonating a Mozilla server could surreptitiously install malware on a user's machine.
While it can be challenging to hack a certificate authority or trick one into issuing the necessary certificate for addons. Such an attack, however, was only viable at certain periods when Mozilla-supplied "pins" expired. The tool, called Daily Validation Reports, will give banks and other clients the ability to review a daily summary of their messages. According to a press release issued by the Brussels-based cooperative, the tool is slated for release in December and will help customers verify message activity and tip them off to any unusual patterns.
High numbers of attacks are also emanating from Russia, Germany, the Netherlands, Ukraine and Vietnam. Poor security on many IoT devices makes them soft targets and often victims may not even know they have been infected.
Attackers are now highly aware of lax IoT security and many pre-program their malware with commonly used and default passwords. IoT attacks have long been predicted, with plenty of speculation about possible hijacking of home automation and home security devices. However, attacks to date have taken a different shape.
Attackers tend to be less interested in the victim and the majority wish to hijack a device to add it to a botnet, most of which are used to perform distributed denial of service DDoS attacks.
The reason behind the ever-growing number of attacks on these devices is simple: Naturally, the banking industry is reacting to these attacks by implementing a range of security measures, but the threat landscape is continually evolving.
The report will — we hope — help the industry to better prepare for a new generation of attack tools and techniques. The report comprises two papers in which we analyze all existing methods of authentication used in ATMs and those expected to be used in the near future, including: The distributed denial of service DDoS attack was aimed at the website of industry expert Brian Krebs.
At its peak, the attack aimed gigabits of data a second at the site. Text found in attack data packets suggested it was mounted to protest against Mr Krebs' work to uncover who was behind a prolific DDoS attack.
In a blogpost, Mr Krebs detailed the attack, which began late on Tuesday night and quickly ramped up to its peak attack rate. DDoS attacks are typically carried out to knock a site offline - but Mr Krebs' site stayed online thanks to work by security engineers, who said the amount of data used was nearly twice the size of the largest attack they had ever seen. The malware, according to researcher Caleb Fenton with security firm SentinelOne, evades detection simply by counting the number of documents — or the lack thereof — that reside on a PC and not executing if a certain number are not present.
Fenton, who discovered the malware after several failed attempts to trigger the sample into acting maliciously, said the typical lack of documents in a virtual machine and sandboxed test environment make it easy, in this case, for malware authors to fly under the radar.
While sources were unspecific about the extent of the incursion, since there is the likelihood of government investigations and legal action related to the breach, they noted that it is widespread and serious. Earlier this summer, Yahoo said it was investigating a data breach in which hackers claimed to have access to million user accounts and one was selling them online.
The scale of the liability could bring untold headaches to the new owners. Shareholders are likely to worry that it could lead to an adjustment in the price of the transaction.
