Hot on the heels of Yahoo announcing a data breach of 500 million user accounts in September, the company has announced that they have suffered another breach of one billion accounts. Yes, you read that correctly- one BILLION accounts.
As Yahoo previously disclosed in November, law enforcement provided the company with data files that a third party claimed was Yahoo user data. The company analyzed this data with the assistance of outside forensic experts and found that it appears to be Yahoo user data. Based on further analysis of this data by the forensic experts, Yahoo believes an unaut...
The attack campaign, dubbed Gooligan, has breached the security of over one million Google accounts and is still growing at a rate of 13,000 new infections each day.

In the past few weeks, fake apps have been popping up in the Apple App Store- right as the holiday shopping season goes into full swing. Most of these apps are masquerading as high-end, designer brands offering the luxury goods for a discount.
Luckily, Apple has already stepped in and removed hundreds of the fake apps that have been reported. While Apple has a very thorough app vetting process in order to prevent malicious and fraudulent apps, these particular apps are skating by because the developer is changing the content of the app after Apple has approved it.
How To Spot A Fake App:...
*Updated October 25th 2016 to include new information about the incident.
Starting in the early hours of Friday, October 21, 2016, a Distributed Denial of Service (DDoS) attack flooded one of the largest DNS server companies in the world, bringing half the Internet to a screeching halt.
It began when the east coast experienced difficulty accessing a slew of major, well-known websites and services. When trying to access these sites, users were greeted with slowness as well as an “unable to reach server” page, denying them access to the websites. It was later confirmed that the Mirai malwa...

Researchers at Symantec have recently discovered a malicious app that can steal photos and videos from the popular instant messaging and VoIP app Viber. The malicious app, Beaver Gang Counter, which was available on Google Play, positions itself as a score-keeping app for a card game. Instead of helping you keep score, it secretly searches for the directories that Viber uses to store images and video files, which it then sends to a remote server.
This type of data could reveal host of personally identifiable information (PII). It is said that a photo is worth a thousand words, and in this...
Although Dridex (W32.Cridex) and Locky (Trojan.Cryptolocker.AF) have been unusually quiet, a new type of ransomware may be taking their place on the online threat landscape. Bart, a new ransomware variant, introduced by the same cybercriminal group behind Dridex and Locky, was spotted late last week.
Are your Apple AirPorts suddenly flashing yellow? That’s because Apple has sent out a major update to your AirPort Express, AirPort Extreme, and AirPort Time Capsule base stations.
A sudden drop in cybercrime activity related to major threat families Locky, Dridex, and Angler have Symantec cybersecurity experts taking note, but still keeping a vigilant eye on the associated malware gangs. One reason for the decrease may be the arrest of 50 people in Russia thought to be involved in the group behind the Lurk banking fraud.
FLocker (short for "Frantic Locker") ransomware is now capable of locking up Android TV sets. This particular ransomware strain is not new, as it has been posing a threat to Android smartphones since May 2015. There are several thousand variants of this strain of malware, and one has now made its way onto smart televisions running Android OS.
While this variant of malware does not encrypt files on the infected device, it does lock the screen, preventing the user access to the TV. Additionally, this malware has the potential to steal data from the device.

A hacker group that calls itself OurMine claims that it has gained access to several of social media tech giant, Mark Zuckerberg’s social media accounts, as a result of the 2012 LinkedIn data breach. Zuckerberg is the latest example of what can happen when you create and reuse weak passwords. What is surprising is how weak his password was. According to the hackers, his password was “dadada.” However, his Facebook account remains intact and best practices have been employed to secure his compromised accounts.
Are you a victim too?
The LinkedIn data breach reportedly exposed 117 million...
Over 2,500 Twitter accounts have been taken over by scammers and are tweeting links to adult dating and sex personals websites. Once the accounts were compromised, the attackers essentially “rebranded” the account by changing profile photos, biographies, and name of the accounts to match the websites they were promoting.
Symantec has been investigating this issue, and they have found that there were a few high profile accounts that had followers from 20,000 upwards to hundreds of thousands that had been compromised.
How to Secure Your Twitter Account
It seems that these attackers are...
In 2012, LinkedIn suffered a data breach of six million user account names and passwords. Apparently, that breach is extremely larger than originally reported.
A Russian hacker going by the name of “Peace” has claimed responsibility for the 2012 hack. This hacker has now resurfaced, and instead of just the six million credentials, he is selling a whopping 117 million credentials on the Dark Web acquired from that same breach.
This hacker waited four years to release the data on the black market.
This just goes to show how important it is to use strong and unique passwords for each servic...

One of the most prevalent Android ransomware threats in the West has now expanded to Asia, choosing Japan as its first target. Android.Lockdroid was spotted on March 11th, and disguises itself as a system update. Once the ransomware detects that it’s installed on a device in a certain country, it displays the ransom message in that country’s language. This is the first type of “chameleon” ransomware we’ve spotted. Once the ransomware is installed and running on the device, it “phones home” to the cybercriminal’s server, and then uploads the device’s information to figure out the phone’s la...
There’s a perception that OS X is impenetrable, especially when compared to Windows. In recent times this assumption is being proven wrong.
The latest in a series of flaws discovered in OS X and iOS is a vulnerability in Apple’s security system. The shortcoming showed up in the System Integrity Protection (SIP), a security feature that Apple introduced with El Capitan last year. SIP was designed to prevent modifications to protected files and folders on Mac. The OS X bug has not only bypassed SIP but can also be used to make malware harder to remove from an infected system.
It’s tax season, so our finances are top of mind for many of us. Cybercriminals are thinking about our money, too. After all, most cybercrimes are committed for monetary gain.

Between March 4th and 5th, 2016, Apple customers were the targets of the first Mac-focused ransomware campaign seen in the wild. These users downloaded a compromised version of the installer for the Transmission BitTorrent client. The malicious Trojan, known as OSX.Keranger, like most ransomware, will encrypt a user’s files and demand a fee (in this case, one Bitcoin, or ~$400) to release the files.
With the IRS’s due date of April 18th looming overhead, fraudsters are rapidly trying to cash in on tax refunds. Over the past two weeks, we’ve seen an increase of BEC (business email compromise) fraudster scams involving requests for employee’s W2 taxpayer information. In this scam, the scammer pretends to be a member of upper management, and targets a more junior member of the organization. The phishing email requests that the target send employees’ W2 forms for inspection.

More than half of respondents globally (56 percent) say the prospect of the financial and banking information stored on their phone being hacked is upsetting. What is more striking is that nearly half either do not care about their information being hacked or they are...
It’s sad to say, but cybercriminals have learned how to use our emotions against us. When we read media reports about accidents or watch videos of natural disasters on the news, it’s normal to feel empathy for the victims of tragic current events, or even concern for our own safety. Unfortunately, that’s when scammers have learned that we are at our most vulnerable, and they have an array of tools to take advantage of that. Here are just a few of the standard Internet scams that fraudsters trick us into.

Malicious software that uses encryption to hold data for ransom has become wildly successful over the last few years. The purpose of this software is to extort money from the victims with promises of restoring encrypted data. Like other computer viruses, it usually finds its way onto a device by exploiting a security hole in vulnerable software or by tricking somebody into installing it. Ransomware, as it is known, now scores high profile victims like hospitals, public schools and police departments.
The nefarious ransomware business model has turned out to be a lucrative industry for cri...
