Pensacola Residents Warned of Evolving CryptoLocker Ransomware Threat

From the sandy shores of Pensacola Beach to the historic downtown district, Pensacola computer users and businesses are urged to exercise extreme caution as a more aggressive version of the CryptoLocker ransomware virus continues to spread. First reported in September 2013, this malware encrypts critical files on infected computers, demanding a ransom for their release.

The CryptoLocker virus targets common file types such as pictures and documents, using a combination of AES and RSA encryption. Once files are encrypted, they become inaccessible to the user. The virus then displays a payment program, demanding $300 USD within 96 hours. Failure to pay within this timeframe reportedly results in the destruction of the encryption key, rendering the files unrecoverable. Experts note that cracking this encryption through brute force would take a supercomputer years to accomplish.

Contrary to some reports, the virus does not make a computer completely unusable. Its creators require the infected machine to remain functional for the ransom payment. While the virus itself can be removed, the only known method to recover encrypted files currently is to pay the ransom, though there is no guarantee of file restoration even then.

The most common method of infection is through email attachments disguised as legitimate correspondence from shipping companies like FedEx, DHL, and UPS. These emails often target company addresses and contain ZIP files. Inside the ZIP, a file may appear to be a PDF but is actually an executable (.exe) file, often with a hidden extension. Users can reveal these hidden extensions in Windows Explorer by adjusting folder options (Tools > Folder Options > View > uncheck “Hide extensions for known file types” for Windows XP, Vista, 7; or View tab > check “File name extensions” for Windows 8).

Pensacola Computers, a local computer repair and service provider since 2003, advises residents to never run any .EXE file from an email unless the sender and the specific file are verified. When in doubt, users should contact the sender directly before opening any attachment.

Another concern is that computers already infected with other malware, such as those part of a botnet, can automatically download CryptoLocker. Keeping antivirus and antimalware software up to date and performing regular scans is crucial. The virus poses a significant threat to businesses, including those along the vibrant Palafox Street corridor, as it can encrypt files on mapped network drives, potentially compromising shared and stored data on servers.

Without shadow copies enabled or off-site backups (not on mapped network drives), encrypted documents may be permanently lost. Pensacola Computers recommends online backup solutions like iDrive or Carbonite. While the virus is relatively easy to remove, doing so after encryption means users would need to manually reinstall it to pay the ransom. Bleepingcomputer.com offers detailed information and removal instructions, though these tools may become ineffective if the virus evolves further.
