Many companies already had a few employees equipped to work remotely, but with most office workers working from home during the pandemic, multiple new points of entry for hackers opened up, Cammilleri said.
Hackers could attempt to find holes in the system caused by human error when trying to shift to remote work, Cammilleri said. They could also attempt more sophisticated phishing scams — email campaigns that attempt to get the reader to reveal personal information or download malicious software.
“I send a phishing email, they click on it, and basically I compromised their system,” Cammilleri said. “Now I’m logged onto their computer, which has corporate access, and game over.”
For individuals, stolen credit cards, online accounts or Social Security numbers can be in jeopardy, but for corporations, ransomware might be the biggest threat.
Hackers using ransomware break into computers or servers and encrypt mass amounts of data. When the data is encrypted, it can’t be read unless the computer knows the encryption key, so hackers hold that key — and therefore the data — hostage until a certain sum of money is paid.
“Ransomware is one way to make a lot of money really quick and easily,” Cammilleri said.
Sprocket is contracted by Fortune 500 companies, private companies and some municipal governments, Cammilleri said. One of its contracts is with the Milwaukee law firm von Briesen & Roper.
