FOLLOWING a hacking incident which left a Rochester business without vital data computer gurus are warning people to be vigilant.
The business, who do not want to be identified, received a randsomeware email which encrypted their business files and wouldn’t release them until a dollar amount was exchanged.
Computer technician Damian McGuiness, who has been helping the business, said there were a few things to keep yourself and your business safe.
‘‘There is no guarantee to defend against randsomeware, but back ups are important,’’ he said.
‘‘They need to be not always connected to the core system, for example hard drives.
‘‘Make sure you disconnect and also have a secondary online backup, like dropbox or drivers.
‘‘It is the quickest way to recover from a hit.’’
Unfortunately there is no way to get everything back once the hackers have their hands on the data.
‘‘Engineers say the only way to get everything back is to pay the amount asked,’’ Mr McGuiness said.
‘‘It is a business model so they normally stick to what they say.
‘‘The rate of getting the info back once paid is very good but you are essential paying criminals.
‘‘You need to contact the police if it happens to you.
‘‘Hold onto your encrypted data because chances are months down the track an agency might find a way to fix it.
Mr McGuiness wanted to warn businesses as they are the ones being targeted.
‘‘At the moment it is only businesses but offsite backups are the key for every computer user,’’ he said.
