Top Cyber Stories of the Last Week
Ransomware Gangs Made At Least $350 Million In 2020
Ransomware gangs made at least $350 million in ransom payments last year, in 2020, blockchain analysis. The figure was compiled by tracking transactions to blockchain addresses linked to ransomware attacks. Although Chainalysis possesses one of the most complete sets of data on cryptocurrency-related cybercrime, the company said its estimate was only a lower bound of the true total due.

Home Working Increases Cyber Security Fears
"We see tens of different hacking attacks every single week. It is never ending."A senior computer network manager says they are bombarded from all directions. "We see everything," he says. "Staff get emails sent to them pretending to be from the service desk, asking them to reset their log-in passwords. "We see workers being tricked into downloading viruses from hackers demanding ransoms, and we have even had employees sent WhatsApp messages pretending to be from the CEO, asking for money transfers.

3.2 Billion Emails And Passwords Exposed Online
A whopping 3.2 billion password-username pairs are up for grabs in an unnamed online hacking forum. But don't panic — the data is nothing new. It's a compilation of stolen credentials from dozens of old data breaches, some going back ten years. That doesn't mean you shouldn't be aware that your old passwords are floating out there. Yes, your passwords, and ours too. Pretty much anyone who's ever created more than three online accounts has had a password compromised by now.

Account Takeover Attacks Spiked In 2020
Occurring whenever a bad actor can steal login credentials and seize control of an online account, takeover attacks rose from 34% of fraud detected in 2019 to 54% by the end of December 2020. Other methods of fraud were blips on the radar compared to account takeovers: The next most popular method, at just 16% of detected fraud, was money laundering/mule transactions, followed by new account fraud (14%), and a mere 12% of instances used remote access or hacking tools to accomplish their goals.

30% Of “Solarwinds Hack” Victims Didn’t Actually Use Solarwinds
When security last week that it had been targeted by the same attacker that compromised SolarWinds' Orion software, it noted that the attack did not use SolarWinds itself. According to Malwarebytes, the attacker had used "another intrusion vector" to gain access to a limited subset of nearly a third of the organizations attacked had no direct connection to SolarWinds.
Data Leakage Attacks Saw Huge Rise In 2020
The number of data leakage incidents grew by an “unprecedented” rate in 2020, a new report from Imperva argues. Through online means alone, not counting leaks caused by lost hardware or word of mouth, Imperva researchers tracked a 93 percent rise. By the end of the year, Imperva had identified a total of 1.7 million leaks, with the the number growing even faster in the second half of the year. Between Q3 and Q4, there was a 47 percent increase.

Automated Tools Increasingly Used to Launch Cyber Attacks
Cyber-criminals are increasingly making use of automation and bots to launch attacks, according to a new analysis. revealed that over half (54%) of all cyber-attacks it blocked in November and December were web application attacks which involved the use of automated tools. The most prevalent form was fuzzing attacks, making up around one in five (19.5%). This uses automation to detect and exploit the points at which applications break. This was followed by injection attacks (12%), in which cyber-criminals make use of automation tools such as sqlmap to gain access to applications.

A Second SolarWinds Hack Deepens Third-Party Software Fears
It’s been more than two months since revelations that alleged Russia-backed hackers broke into the IT management firm SolarWinds and used that access to launch a massive software supply chain attack. It now appears that Russia was not alone; Reuters reports that suspected Chinese hackers independently exploited a different flaw in SolarWinds products last year at around the same time, apparently hitting the US Department of Agriculture's National Finance Center.

93% Of Workers Overshare Online, Causing Security Risks
Reveals just how much, and how often, people divulge about their lives online and how attackers take advantage of it. With insights from both professionals and hackers, the report explores how cybercriminals use an abundant and seemingly cheap resource — the personal information people share on social media and in out-of-office alerts — to craft social engineering attacks.

Is There A Widening Gulf Between You And Your Remote Workers? Yes – And It’s Security Shaped
It’s been almost a year since large parts of the workforce beat a hasty retreat from their offices, and began a mass experiment in working from home, often courtesy of Microsoft 365. And after 12 or so months, it’s safe to say that the case for productive remote working has been proved, and that many workers will continue to do so even when the all clear sounds. But is there a question as to whether remote working is as secure as the traditional, office bound, hard perimeter setup? Well, yes, and it’s fair to say the jury is still very much out.
