Threats
Ransomware
Manchester United hackers 'demanding million-pound ransom'
Manchester United are still suffering the effects of a significant cyberattack that targeted the club earlier this week.
Following last weekend's 'sophisticated' attack, the club has revealed it is still suffering severe disruption to its internal systems, several of which had to be shut down following the incident.

Egregor Ransomware Attack Hijacks Printers to Spit Out Ransom Notes
The South American retail giant Cencosud was hit with ransomware last week? The retailer was infected by an Egregor ransomware attack which, in time honoured fashion, stole sensitive files that it found on the compromised network, and encrypted data on Cencosud’s drives to lock workers out of the company’s data.
A text file was left on infected Windows computers, telling the store that private data would be shared with the media if it was not prepared to begin negotiating with the hackers within three days.
That’s nothing unusual, but Egregor’s novel twist is that it can also tell businesses that their computer systems are well and truly breached by sending its ransom note to attached printers.
Sopra Steria: Adding up outages and ransomware clean-up, Ryuk attack will cost us up to €50m
Sopra Steria has said a previously announced Ryuk ransomware infection will not only cost it "between €40m and €50m" but will also deepen expected financial losses by several percentage points.
The admission comes weeks after the French-headquartered IT outsourcing firm's Active Directory infrastructure was compromised by malicious people who deployed the Ryuk ransomware, using what the company called "a previously unknown strain."

Phishing
GoDaddy scam shows how voice phishing can be more deceptive than email schemes
Companies can protect employees from phishing schemes through a combination of training, secure email gateways and filtering technologies. But what protects workers from phone-based voice phishing (vishing) scams, like the kind that recently targeted GoDaddy and a group of cryptocurrency platforms that use the Internet domain registrar service?
Experts indicate that there are few easy answers, but organizations intent on putting a stop to such activity may have to push for more secure forms of verification, escalation procedures for sensitive requests, and better security awareness of account support staffers and other lower-level employees.
Google Services Weaponized to Bypass Security in Phishing, BEC Campaigns
A spike in recent phishing and business email compromise (BEC) attacks can be traced back to criminals learning how to exploit Google Services, according to research from Armorblox.
Social distancing has driven entire businesses into the arms of the Google ecosystem looking for a reliable, simple way to digitize the traditional office. A report detailing how now-ubiquitous services like Google Forms, Google Docs and others are being used by malicious actors to give their spoofing attempts a false veneer of legitimacy, both to security filters and victims.
Malware
Malware creates scam online stores on top of hacked WordPress sites
A new cybercrime gang has been seen taking over vulnerable WordPress sites to install hidden e-commerce stores with the purpose of hijacking the original site's search engine ranking and reputation and promote online scams.
The attacks were discovered earlier this month targeting a WordPress honeypot which was set up and managed.
The attackers leveraged brute-force attacks to gain access to the site's admin account, after which they overwrote the WordPress site's main index file and appended malicious code.

Google Chrome users still vulnerable to multiple zero-day attacks
As business users and consumers have moved most of their workloads to the cloud, more and more of their work is being done in web browsers such as Google Chrome as opposed to in applications installed locally on their systems.
This means that the web browser is now an essential yet vulnerable entry point that if compromised, could give cybercriminals access to a user's entire digital life including their email, online banking, social networks and more. However, despite this risk, users are failing to update to the latest version of Google Chrome.
