Microsoft Customer Guidance for WannaCrypt attacks

Posted on May 15, 2017


Microsoft solution available to protect additional products

Today many of our customers around the world and the critical systems they depend on were victims of malicious “WannaCrypt” software. Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful. Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers. This blog spells out the steps every individual and business should take to stay protected. Additionally, we are taking the highly unusual step of providing a security update for all customers to protect Windows platforms that are in custom support only, including Windows XP, Windows 8, and Windows Server 2003. Customers running Windows 10 were not targeted by the attack today.

Details are below.

  • In March, we released a security update which addresses the vulnerability that these attacks are exploiting. Those who have Windows Update enabled are protected against attacks on this vulnerability. For those organizations who have not yet applied the security update, we suggest you immediately deploy Microsoft Security Bulletin MS17-010.
  • For customers using Windows Defender, we released an update earlier today which detects this threat as Ransom:Win32/WannaCrypt. As an additional “defense-in-depth” measure, keep up-to-date anti-malware software installed on your machines. Customers running anti-malware software from any number of security companies can confirm with their provider, that they are protected.
  • This attack type may evolve over time, so any additional defense-in-depth strategies will provide additional protections. (For example, to further protect against SMBv1 attacks, customers should consider blocking legacy protocols on their networks).

We also know that some of our customers are running versions of Windows that no longer receive mainstream support. That means those customers will not have received the above mentioned Security Update released in March. Given the potential impact to customers and their businesses, we made the decision to make the Security Update for platforms in custom support only, Windows XP, Windows 8, and Windows Server 2003, broadly available for download (see links below).

Customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March. If customers have automatic updates enabled or have installed the update, they are protected. For other customers, we encourage them to install the update as soon as possible.

This decision was made based on an assessment of this situation, with the principle of protecting our customer ecosystem overall, firmly in mind.

Some of the observed attacks use common phishing tactics including malicious attachments. Customers should use vigilance when opening documents from untrusted or unknown sources. For Office 365 customers we are continually monitoring and updating to protect against these kinds of threats including Ransom:Win32/WannaCrypt. More information on the malware itself is available from the Microsoft Malware Protection Center on the Windows Security blog. For those new to the Microsoft Malware Protection Center, this is a technical discussion focused on providing the IT Security Professional with information to help further protect systems.

We are working with customers to provide additional assistance as this situation evolves, and will update this blog with details as appropriate.

Ransomware: Lessons learned

Don’t say that we didn’t warn you (see here, here and especially here). Here’s a tale about a synagogue in the NYC area, but it could happen to anyone.

In mid-November the rabbi’s secretary was going about her business on the shul computer. Whether she was duped to click on an infected popup advertisement or she visited an infected website the damage was done. What we do know is that this ransom note appeared on her screen:

ransomware-warning

Then the panic. The note was accurate, they were locked out of the shul’s only computer. What should the shul do?

  • They couldn’t get to their Quickbooks.
  • They couldn’t get to their member software.
  • They couldn’t get to the file with the Yahrzeits.
  • They couldn’t get to their record of Kol Nidre pledges

Some computer-savvy members tried various tools, but no luck. The problem was eventually brought to the synagogue board and a hearty debate followed. Would they just be paying a ransom and get nothing in return (See the FBI guidance here)?  Finally, the vote was to pay the ransom, 3 bitcoins (almost $2,400).  Fortunately, the thieves were relatively honest. The synagogue’s files were decrypted and they could recover their data. Many other victims pay, but their computers remain locked.

Lessons learned

People, there’s nothing new here. Check out JCRC-NY’s Cybersecurity Resources page and our cybersecurity blog posts. This episode is an expensive reminder that it’s crucial to practice good cyber-hygiene.

  1. Backup, backup, backup. There is no excuse. External thumb drives and hard drives are cheap. Buy one and take the time to configure the backup program so that it automatically, regularly keeps critical data safe. There are many free or low-cost cloud options. Backup to Google Drive, Dropbox or a cloud server provided by your anti-virus/backup program. The data in some shul membership management programs are automatically saved to the cloud which may even be monitored by full-time cybersecurity staff. Finally, more than one backup (e.g., one onsite, one offsite or in the cloud)  is better than one … one is better than none.
  2. Keep your anti-virus software up-to-date. The bad guys are smart and they’re getting smarter. Somehow, the bad guys got the rabbi’s secretary to click on the infected link. Our poor synagogue had anti-virus software, but it was a year out-of-date (duh, it turns itself off).  Most of the better anti-virus programs are updated constantly and will probably stop a ransomware attack before your data is seized. Buy a license that will protect all of your computers. (see bargain software rates for nonprofits at Techsoup).
  3. Have strong passwords and record them. Whoever set up the synagogue’s computer did follow “best practice” and didn’t give the users “Administrator” access (pardon the techy-talk). The trouble was that no one knew that password so the consultant who assisted the synagogue had to get permission from the board to reset the password before she could revive the computer.

  4. Beware of residual “bread crumbs”. Some ransomware leaves malware on a computer so that the bad guys can re-infect the computer. After all, you paid once, won’t you pay again? Once you have recovered the encrypted files, use multiple products to scan your computer: first your new, up-to-date anti-virus program, then a some others (the trial or basic versions are available free online) such as Malwarebytes, CCleaner, SUPERAntispyware, to name a few. There is no perfect solution. Each may find something that the others missed.
  5. Cybersecurity is a board responsibility. The incident was an expensive lesson. When no one on staff has computer skills, the board has a fiduciary responsibility to make sure that the staff know the basics of cyber-hygiene: the software is being updated, the backups are made, the anti-virus programs are working.

Finally, kudos to JCRC-NY’s outside computer maven from Dragonfly Technologies, who dropped everything to travel to the shul and spent many hours into the night to get them back in business and up-to-date.

Phishing: Will you be a victim?

Phishing attacks — usually giving you a plausible reason to “change” your password — have increased. Once they have your account information many criminal avenues open up. Here’s some background and good advice from Stratfor.

It’s National Cyber Security Awareness Month

Cyber Security is Everyone’s Responsibility

Data breaches resulting in the compromise of personally identifiable information of thousands of Americans. Intrusions into financial, corporate, and government networks. Complex financial schemes committed by sophisticated cyber criminals against businesses and the public in general.

These are just a few examples of crimes perpetrated online over the past year or so, and part of the reason why Director James Comey, testifying before Congress last week, said that “the pervasiveness of the cyber threat is such that the FBI and other intelligence, military, homeland security, and law enforcement agencies across the government view cyber security and cyber attacks as a top priority.” The FBI, according to Comey, targets the most dangerous malicious cyber activity—high-level intrusions by state-sponsored hackers and global cyber syndicates, and the most prolific botnets. And in doing so, we work collaboratively with our domestic and international partners and the private sector.

But it’s important for individuals, businesses, and others to be involved in their own cyber security. And National Cyber Security Awareness Month—a Department of Homeland Security-administered campaign held every October—is perhaps the most appropriate time to reflect on the universe of cyber threats and on doing your part to secure your own devices, networks, and data.

What are some of the more prolific cyber threats we’re currently facing?

Ransomware is type of malware that infects computers and restricts users’ access to their files or threatens the permanent destruction of their information unless a ransom is paid. In addition to individual users, ransomware has infected entities such as schools, hospitals, and police departments. The actors behind these sophisticated schemes advise the users that if they pay the ransom, they will receive the private key needed to decrypt the files. Most recently, these cyber criminals—demonstrating some business savvy—give victims the option of decrypting one file for free to prove that they have the ability to restore the locked files.

Business e-mail compromise, or BEC, scams continue to impact many businesses across the U.S. and abroad. BEC is a type of payment fraud that involves the compromise of legitimate business e-mail accounts—often belonging to either the chief executive officer or the chief financial officer—for the purpose of conducting unauthorized wire transfers. After compromising a company’s e-mail account—usually through social engineering or malware—the criminals are then able to send wire transfer instructions using the victim’s e-mail or a spoofed e-mail account. BEC scams have been reported in all 50 states and in 100 countries and have caused estimated losses of more than $3 billion worldwide. More on BEC scams.

Intellectual property theft involves robbing individuals or companies of their ideas, inventions, and creative expressions—often stolen when computers and networks are accessed by unscrupulous competitors, hackers, and other criminals. Intellectual property can include everything from trade secrets and proprietary products and parts to movies, music, and software. And the enforcement of laws protecting intellectual property rights (IPR)—which are critical to protecting the U.S. economy, our national security, and the health and safety of the American public—is an FBI criminal priority. The Bureau’s IPR focus is the theft of trade secrets and infringements on products that can impact consumers’ health and safety, including counterfeit aircraft, automotive, and electronic parts.

“The FBI is doing everything we possibly can, at every level, to make it harder for cyber criminals to operate,” says Associate Executive Assistant Director David Johnson, “and I believe many of them are now starting to think twice before they put fingers to keyboard. But we also ask that the public do its part by taking precautions and implementing safeguards to protect their own data.”

Check back on our website during the month of October for information on protecting your data and devices and on FBI efforts to combat the most egregious cyber criminals.
