Hacker collects 272m email addresses and passwords, some from Gmail

Security firm announces it has persuaded fraudster to give up database of email addresses along with passwords users use to log in to websites

hacking gmail

The internet on Wednesday gave you another reminder that everyone has been hacked.

Hold Security, a Wisconsin-based security firm famous for obtaining hoards of stolen data from the hacking underworld, announced that it had persuaded a fraudster to give them a database of 272m unique email addresses along with the passwords consumers use to log in to websites. The escapade was detailed in a Reuters article.

It might sound bad, but it is also easily mitigated.

The passwords and email addresses, which include some from Gmail, Yahoo and Russia’s mail.ru service, aren’t necessarily the keys to millions of email accounts. Rather, they had been taken from various smaller, less secure websites where people use their email addresses along with a password to log in.

People who use a different password for both their email account and, say, Target.com, won’t be affected. But those who tend to use the same password for multiple sites as well as their email should change their email password.

“Some people use one key for everything in their house,” Hold Security founder Alex Holden says. “Some people have a huge set of keys that they use for each door individually.”

Holden said there is no way for consumers to check if their emails were included in his firm’s latest find. In 2014, when his firm tried to set up such a service after obtaining a billion hacked login credentials, his site crashed.

The hacker appears to have been largely targeting Russian users. Some 57m of the email addresses were for the country’s largest email provider mail.ru, which claims 100 million monthly users. Around 40m of the addresses were Yahoo Mail, 33m Hotmail and 24m for Google’s Gmail service.

In this case, the hacker had been bragging on internet chat forums that he had a treasure trove of login credentials that he was trying to sell. Holden, who is fluent in Russian, said he wouldn’t pay for the data but would give him “likes” on various social media posts in exchange.

The hacker, who apparently is quite young, agreed. “We kind of call him the collector,” Holden says in a heavy Russian accent. “Eventually, almost everyone gets breached.”

Ransomware-as-a-service is exploding: Be ready to pay

RaaS has outgrown smaller targets and now threatens governments, NGOs, and SMBs.

ransomware

It starts with a fast click on a link in a harmless-looking email. Then your PC slows to a crawl. A message suddenly pops up and takes over your screen. “Your files and hard drive have been locked by strong encryption. Pay us a fee in 12 hours, or we will delete everything.” Then a bright red clock begins counting down. No antivirus will save your machine. Pay the fee or lose everything.

You’re the latest victim of a ransomware attack. The scary thing is, you’re not alone. The ransomware market ballooned quickly, from a $400,000 US annual haul in 2012, to nearly $18 million in 2015. The average ransom—the sweet spot of affordability for individuals and SMBs—is about $300 dollars, often paid in cash vouchers or Bitcoin.

The ransomware market scaled up so quickly, claims a recent report by Imperva, due to the rise of ransomware-as-a-service, or RaaS. Here’s how it works:

  • Ransomware authors are marketing on-demand versions of code, using traditional malware distributors in a classic affiliate model.
  • The ransomware author collects the ransom and shares it with the distributor.
  • Malware is distributed through spam email messages, malicious advertisements, and BlackHat SEO sites.
  • According to the Imperva report, “in classical affiliate marketing, the larger cut goes to the possessor of the product. In RaaS … the ransomware author gets a small cut of the funds (5%-25%) while the rest goes to the distributor (affiliate).”
  • Using the deep web, TOR, and Bitcoin, the report says, “this model, based on TOR and Bitcoins, is designed to keep the identity of the author and the distributor hidden from law enforcement agencies.”

Phishing in particular, is a highly effective tactic for malware distribution.

The well-worded email appears to come from a legitimate email address and domain name, and raises very few irregularities. The email comes with a demand for money for an arbitrary service, along with a link that purports to be an “overdue invoice.”

Click that link and open the file (which looks like a Word document), and you’ll become the latest victim of ransomware — that is, malware that encrypts your files and locks you out of your computer until you pay a ransom.

Phishing attacks have also helped ransomware move into the enterprise. In 2015 the medical records system at Hollywood Presbyterian Medical Center was attacked. The hospital paid $17,000 in Bitcoin to unlock the sensitive records. In early 2016 the Lincolnshire County Council was snagged by a phishing scheme and held up for 500 dollars.

To prevent your business from attack, make sure the IT department and communication team are in sync, keep your company’s security systems updated, and remind employees to use caution when clicking on email links from unknown addresses.

If you’ve been hacked, the ransomware rescue kit provides a suite of tools designed to help clean particularly pugnacious malware.

Businesses that suffer ransomware attacks face a tough choice. Paying the fee could restore access to mission-critical data, but there’s no guarantee the extortionists will honor the deal. And of course, paying a ransom provides incentive to hackers and validates the attack.

5 free anti-malware tools; VR terms you should know

There’s plenty of free, effective anti-malware protection available. Just don’t let it push your browser around.

Although malware was once predicted to become extinct, it remains a constant threat. Thankfully, countless tools are available to help protect your PC against such security threats—including the popular (and free) anti-malware products on this list.

: AVG AntiVirus Free

AVG AntiVirus Free (Figure A) provides protection for your computer, your browser, and your mail client. Like many other free products, AVG AntiVirus Free tries to sell you a paid license, which includes an enhanced firewall, anti-spam protection, and a few other features.

Figure A

AVG-SJTechies

Although AVG AntiVirus Free seems to do a good job protecting systems against viruses, you have to be careful about the options you choose when installing and configuring this product. Otherwise, AVG will attempt to “hijack” your browser by installing AVG Web TuneUp, changing your search page, changing your new tab pages, and changing your home page.

2: Malwarebytes Anti-Malware Free

Malwarebytes Anti-Malware Free (Figure B) offers basic protection against malware. There are two main things I like about this app. First, unlike some of the other free anti-malware products, it doesn’t try to change your browser settings or install unwanted toolbars. Second, it has a clean and intuitive interface that doesn’t leave you guessing about what to do.

Figure B

The disadvantage to using Malwarebytes Anti-Malware Free is that unlike the premium version, it does not support real-time protection. You can scan your PC for malware at any time, but you won’t be alerted to infections in real time unless you upgrade to the paid version.

3: Avast Free Antivirus 2016

Avast Free Antivirus 2016 (Figure C) is probably the most comprehensive antivirus tool on this list. It offers 12 components, including Rescue Disk, Browser Cleaner, Web Shield, and File Shield. The installer lets you choose which components to install.

Figure C

Avast-SJTechies

During the hour or so that I used Avast Free Antivirus, it did not attempt to take over my browser or engage in any other obnoxious behavior. The software does, however, prominently display a warning message during the installation process telling you in no uncertain terms that Avast Free Antivirus 2016 collects personal information. At least it gives you a way to opt out of this data collection.

4: Panda Free Antivirus

Panda Free Antivirus (Figure D) is another free anti-malware solution that requires a bit of caution during the installation process—otherwise, Panda will install a browser toolbar and change your home page and your default search provider.

Figure D

PandaAntivirus-SJTechies

The free version of Panda Antivirus offers real-time protection against malware, but it does try to get you to upgrade to the paid version. That version, which Panda refers to as the Pro Edition, adds a firewall, Wi-Fi protection, and VIP support.

5: YAC

YAC (Figure E) stands for Yet Another Cleaner and—you guessed it—it’s yet another free tool for blocking threats and removing malware from an infected system. It offers a simple, easy-to-follow interface, and it doesn’t try to hijack your browser (which is a personal pet peeve, in case you hadn’t noticed). In fact, the software gives you a way to lock your browser settings so that your preferred home page, default browser, and default search engine can’t be changed without your consent.

Figure E

YAC-SJTechies

In addition to its basic anti-malware capabilities, YAC includes some nice extras, such as a tool for speeding up your computer, an uninstaller, and an ad blocker. The primary disadvantage to using YAC is that you have to upgrade to the paid version if you want to receive real-time protection. Otherwise, you’ll have to initiate anti-malware scans manually.
