Ransom ware is a variety of malware that, once it infects its host-machine, at least says it’s encrypted the data on or locked its victim’s machine in some other way. The malware then informs the infected user that he or she must pay a ransom in order to unlock their files. Of course, there is never any guarantee whatsoever that paying the ransom will unlock anything. In this case the Cryptolocker really carries out the threat, The virus encrypts files stored on local hard drives and mounted network drives using public-key cryptography, and then displays a message saying that the files will be decrypted by a 2048-bit RSA key pair if a fee is paid through an anonymous payment service by a specified deadline, beyond which decryption is no longer possible. There is no way to decrypt the key.
US-CERT issued an advisory this week warning businesses and consumers of the risks presented by CryptoLocker, which has been on the radar of security experts since late October. US-CERT said infections are on the rise and urge victims not to pay the ransom, instead report it to the FBI’s Internet Crime Complaint Center.
How the virus works – What does it steal from you? Who does it Target?
CryptoLocker installs itself to the Documents and Settings folder on your system and then proceeds to search for specific file types like Microsoft Word Docs or Adobe PDFs. It applies an asymmetric encryption which requires both a public and private key to unlock. The public key is stored in the virus itself and is used to encrypt the files. The private key is hosted on the hacker’s server.
We have noticed a high infection rate here in Baltimore County as well as the surrounding metro Baltimore area. This is serious business for these thugs and for the first time this type of attack is being considered organized crime.
How do I get it?
- As an email sent to company addresses pretending to be from customer support from FedEx, UPS, DHL, etc. The virus is attached to the email, usually labeled as a tracking number.
- In PDF documents that are attached to emails.
- Via hacked websites that can exploit computer vulnerabilities to install the infection.
- Through Trojans that pretend to be programs you need to download in order to watch videos online.
Some versions of CryptoLocker are reportedly capable of affecting not only local files but also files stored in Removable Media such as USB sticks, external hard drives, network file shares and some cloud storage services that are able to sync local folders with online storage. The US-CERT notification also warns that the malware can jump from machine to machine within a network and advises that infected users remove affected machines from their networks immediately.
Can Baltimore PC Repair remove the virus?
The techs and engineers here at Perry Hall PC Repair have had success with removing the virus but at this point it is impossible to retrieve the encrypted files so honestly the best practice is to wipe the hard drive and start over.
IMPORTANT SAFETY INFORMATION
- Beware of attachments – Always look at your attachments. If you get an email with an attachment from any sender you don’t personally know don’t open it. If you get an attachment from people you do know, but it isn’t something they would normally send, don’t open it. For all other attachments, try confirming that the file attached is in fact legitimate by asking the sender.
- Backup your data – Be sure to always backup your data on a regular basis. If you backup files on a daily or even weekly basis and are infected, you can easily wipe your hard drives and start again without losing much in the way of data.
- Know what to do if infected – If you are infected the first thing you should do is disconnect from the network to limit the chance of the virus spreading to other systems. If you have backed up your system and data, you can probably revert your system. If not, your best plan of attack would be to contact us to see if we can help, as we may be able to get around the encryption or even delete it
Home users should also backup to protect against drive failure, theft, and viruses, Data backups aren’t just for companies! There are many inexpensive backup solutions on the market today geared towards home and small business users depending on their needs. Investing in a backup solution can save you hundreds in repair costs and thousands in data recovery charges.
The first questions to ask are:
- How much data are you backing up?
- Is your computer stationary or mobile?
- How sensitive is your data?
Online Backup services
If you don’t have much data (less than five gigabytes) and your data isn’t sensitive an internet backup service might be right for you. Most services offer monthly or annual contracts ranging from $5/month to $50/yr. After joining they provide you with an application that lets you choose which folders to backup. Most services will monitor for file changes and automatically backup files as needed.
- Data is stored offsite protecting you against fire/acts of god
- No extra hardware required
- Good for specific folders (my documents, email, etc)
- Slow backups, performing a full backup can take upwards of a day.
- Services have surcharges depending on bandwidth usage.
- Doesn’t backup the entire hard drive.
Offline Backup Solutions
Unlike online backup services, offline backup solutions store data on an external hard drive or DVD media. These solutions make an image of your hard drive, meaning you can return the computer to exact state of the last backup, not just restore individual files, this is good if your drive fails or you’re infected with a virus. You can buy an external hard drive for under $200 and the software for between $50 and $99, some software will create a recovery partition so no external drive is necessary. Most programs will create a monthly full backup and daily incremental (what’s changed) backup, full backup’s take about an hour to complete and incremental backup’s take a few minutes. As the drive fills up it will delete the oldest full and incremental backup’s to make room for the new.
For stationary laptops and desktops its best to automatically backup to an external hard drive as it protects against drive failure and data loss. If your computer is mobile you can create a recovery partition on your hard drive for backups however it doesn’t protect against drive failure. If you don’t want to carry an external hard drive it’s best to manually run a backup to an external drive when you have a moment.

- Ideal for users with lots of data
- Allows for full system restores

A disaster recovery plan is critical for the health of every small business but, only 25% of the businesses I encounter have a plan in place. Personally, I Feel this is because business owners don’t have a clear idea on what needs to be done; not knowing where to begin, they put off building a disaster recovery plan. A good Plan starts with backing up Business Critical Data.
So Just What is Business Critical Data?
Business critical data includes information your business could not recover if it were lost. Any small business disaster recovery plan should focus on keeping this irreplaceable data safe. That data might include:
- Customer information
- Email correspondence
- Financial records and information
- Sales and shipping records
- Insurance, vendor and employee contact information
- LAN and WAN Network diagrams and IT vendor service level agreements
- Telephone service level agreements
- Drawings or Specification documents
- HR records
- Video or audio records
- Procedures and Policies
- Quality and product tracking records
- Inventory records
- Certificates and Licenses
- Security information
- Manuals, books and other products created for and by your business
- Offsite storage indexes which include what is stored off site, where it’s stored, and when it was update.
Now you have a idea of what Business Critical Data is you can begin putting together your Disaster Recovery Plan.

Heat – is one of the things that damage the most of a computer. Tower desktops are originate so that the fan creates a vortex that helps cooling the parts inside. For laptops and all-in-one computers the space is limited, so it’s harder to an effective airflow to cool down the parts.
