Hackers hacked the site of Johannesburg, the largest city in the Republic of South Africa and the provincial capital Gauteng, and demanded from the authorities a ransom in bitcoins.
The city administration announced a hack in itsofficial Twitter account. Authorities wrote that “an intrusion into the network was discovered that led to unauthorized access to information systems.”
Hacking affected several client systems, includingincluding reference services. Due to the intervention of hackers, some operations to provide public services to the public were suspended. Johannesburg city cybersecurity experts launched an investigation into the incident.
After the attack, cybercriminals calling themselvesShadow Kill Hackers demanded a ransom of 4 BTC, according to local eNCA. Otherwise, hackers threatened to upload all the compromised data to the Internet until October 28:
"If you pay on time, we will destroy all the data we have and send your IT specialist a full report on how we hacked your systems and reveal the weaknesses in the security system."
This is not the first time hackers have been hackinginformation systems of large cities, as often their level of security is far from ideal. Earlier this month, online operations in the Spanish city of Jerez de la Frontera were suspended as a result of an attack by hackers demanding a ransom in bitcoins for unlocking the city's computer systems.
In June, the authorities of the American city of Lake Citythe ransomware paid a ransom of 42 BTC, and a little earlier the administration of the Riviera Beach paid a ransom of 65 BTC to unknown hackers who managed to take control of the city's computer system.</p></p>
